Specific embodiment
Fig. 1 is the flow chart of the first embodiment of the method for excessive heating protection of the uninterrupted power source of the present invention.As illustrated, In step S1, first the main path switch device of at least one circuitry phase of uninterrupted power source and its corresponding bypass switching device are set Put on same radiator (hereafter by this radiator referred to as " intended heat device ").In this step, when this uninterrupted power source When being single-phase uninterrupted power source, the main path switch device of this single-phase uninterrupted power source and bypass switching device can be arranged on same On one intended heat device.When this uninterrupted power source is three-phase uninterrupted power supply, can appointing this three-phase uninterrupted power supply Anticipate the main path switch device of a circuitry phase and bypass switching device is arranged on same intended heat device it is also possible to by this three-phase The main path switch device of arbitrarily biphase or three-phase circuit of uninterrupted power source and bypass switching device are separately positioned on two or three On individual intended heat device.
In step s 2, a temperature detection device is arranged on described intended heat device to detect intended heat device temperature Degree.As it was previously stated, when this uninterrupted power source is single-phase uninterrupted power source, can be by the main path switch of this single-phase uninterrupted power source Device and bypass switching device are arranged on same intended heat device, and a described target of temperature detection device setting is dissipated To detect intended heat device temperature on hot device.Preferably, described temperature detection device can be arranged on and be located on intended heat device Position between described main path switch device and described bypass switching device.When this uninterrupted power source is three-phase uninterrupted power supply When, the main path switch device of any one circuitry phase of this three-phase uninterrupted power supply and bypass switching device can be arranged on same It is also possible to by the main path switch device of the arbitrarily biphase of this three-phase uninterrupted power supply or three-phase circuit and side on individual intended heat device Way switch device is separately positioned on two or three intended heat devices, then respectively by one, two or three temperature inspections Survey device and be arranged on described main path switch device and the described bypass switching device positioned at each circuitry phase on described intended heat device Between position.
In step s3, judge described uninterrupted power source mode of operation, and determine in this operating mode described at least One circuitry phase corresponding overtemperature protection point.In the art, uninterrupted power source is usually operated at inverter mode and bypass mode.When When uninterrupted power source is operated in inverter mode, select the overtemperature protection point of described main path switch device mutually electric as described at least one The corresponding overtemperature protection in road point.When uninterrupted power source is operated in bypass mode, select the overtemperature protection of described bypass switching device Point is as the corresponding overtemperature protection point of described at least one circuitry phase.In the art, uninterrupted power source is likely to be operated in inversion Pattern, bypass mode or economical operation (ECO) pattern.Therefore, when uninterrupted power source is operated in inverter mode, can will be described The overtemperature protection point of main path switch device is as this circuitry phase corresponding overtemperature protection point;And work as uninterrupted power source and be operated in bypass During pattern or during ECO pattern, using the overtemperature protection point of described bypass switching device as the corresponding overtemperature protection of this circuitry phase Point.In the specific embodiments of this area, uninterrupted power source is also possible to be operated in inverter mode, bypass mode, economical operation (ECO) pattern or from aging mode.Now, when uninterrupted power source is operated in inverter mode, can be by described main path switch device The overtemperature protection point of part is as the corresponding overtemperature protection point of this circuitry phase;And when uninterrupted power source is operated in bypass mode or During ECO pattern, using the overtemperature protection point of described bypass switching device as this circuitry phase corresponding overtemperature protection point;When uninterrupted Power work when from aging mode, using the described corresponding overtemperature protection from aging mode overtemperature protection point as this circuitry phase Point.
Those skilled in the art know, the overtemperature protection point of this main path switch device, the overtemperature protection of bypass switching device Put and can be measured by those skilled in the art according to practical situation from aging mode overtemperature protection point.Generally, from always Change the temperature highest of mode overheat protective point, the overtemperature protection point of bypass switching device takes second place, the overheated guarantor of main path switch device Shield point is minimum.
In step s 4, institute is controlled based on the described corresponding overtemperature protection point of at least one circuitry phase and described radiator temperature State the working condition of uninterrupted power source.Here, maintaining the current operating state of uninterrupted power source to refer to, keep uninterrupted power source Mode of operation, output current, output voltage are all constant.
First it is usually operated at as a example inverter mode and bypass mode by uninterrupted power source below.For example, work as radiator temperature Less than or equal to this at least one circuitry phase overtemperature protection point when it was demonstrated that now uninterrupted power source working properly, now only need Maintain the working condition of this uninterrupted power source.But if radiator temperature is higher than the overtemperature protection of at least one circuitry phase It was demonstrated that the work of uninterrupted power source occurs extremely during point.Now need the working condition of uninterrupted power source is adjusted.Example As when the radiator temperature that uninterrupted power source is only operated in inverter mode and temperature detection device records is higher than this main path switch device Then it is assumed that uninterrupted power source work there occurs exception during the overtemperature protection point of part, now main path switch device will be closed, and will not Uninterruptible power is switched to bypass mode.Now because the mode of operation of this circuitry phase has occurred that change, therefore now need Using the overtemperature protection point of other main path switch device as this circuitry phase overtemperature protection point.Due to generally, by-pass switch The overtemperature protection point of device is higher than the overtemperature protection point of main path switch device.Therefore after carrying out this switching, generally, Radiator temperature is less than the overtemperature protection point of bypass switching device, and now uninterrupted power source can be in bypass normal work. But if uninterrupted power source is operated in bypass mode, and the radiator temperature now detecting also to be above this circuitry phase currently right During the overtemperature protection point answered, illustrate that uninterrupted power source work is still abnormal, now need to be to continue with according to user setup determination Work under abnormal conditions or in order to protect uninterrupted power source, thus closing bypass switching device.
Main path switch device and its corresponding bypass switching device setting due at least one circuitry phase of uninterrupted power source On same radiator, so when described uninterrupted power source work, bypass mode, ECO pattern and during from aging mode, all may be used So that by this radiator, as temperature detecting point, the temperature of this radiator and different overtemperature protections point are compared can (no Uninterruptible power be operated in inverter mode, bypass mode, ECO pattern, from the different pattern such as aging mode when, there are different mistakes Thermal protection point, in the present embodiment, described overtemperature protection point is a temperature value).
Below then by uninterrupted power source be operated in inverter mode, bypass mode, ECO pattern and from aging mode as a example. For example, when radiator temperature is less than or equal to the overtemperature protection point of this at least one circuitry phase it was demonstrated that now uninterrupted power source Working properly, now only need to maintain the working condition of this uninterrupted power source.But if radiator temperature is higher than at least It was demonstrated that the work of uninterrupted power source occurs extremely during the overtemperature protection point of one circuitry phase.Now need the work to uninterrupted power source It is adjusted as state.For example, when uninterrupted power source is only operated in the radiator temperature that inverter mode and temperature detection device record Degree is higher than during the overtemperature protection point of this main path switch device then it is assumed that uninterrupted power source work there occurs exception, now will close Main path switch device, and uninterrupted power source is switched to bypass mode.Now because the mode of operation of this circuitry phase has occurred and that Change, therefore now need using the overtemperature protection point of other main path switch device as this circuitry phase overtemperature protection point.Due to Generally, the overtemperature protection point of bypass switching device is higher than the overtemperature protection point of main path switch device.Therefore carrying out this After switching, generally, radiator temperature is less than the overtemperature protection point of bypass switching device, now uninterrupted power source Can be in bypass normal work.But if uninterrupted power source is operated in bypass mode or ECO pattern, and dissipating of now detecting Hot device temperature be also above this circuitry phase currently corresponding overtemperature protection point when, illustrate that uninterrupted power source work is still abnormal, this When need to be determined according to user setup and be to continue with working in abnormal cases or in order to protect uninterrupted power source, thus closing side Way switch device.Again for example, when uninterrupted power source is operated in from aging mode, and the radiator temperature now detecting also is above This circuitry phase currently corresponding overtemperature protection point when (from aging mode overtemperature protection point), now need also exist for being set according to user Put determination to be to continue with working in abnormal cases or in order to protect uninterrupted power source, thus closing bypass switching device.Due to From aging mode, main road and bypass all can work, and therefore generally higher from the temperature of aging mode overtemperature protection point, it is concrete Numerical value voluntarily can be arranged by user.
Implement the method for excessive heating protection of the uninterrupted power source of the present invention, bypass can be detected using a temperature detection device Switching device and the temperature of main path switch device, thus the bypass switching device to uninterrupted power source and main path switch device are carried out Overtemperature protection, therefore its overtemperature protection design is simple, cost is relatively low.
Fig. 2 is the flow chart of the second embodiment of the method for excessive heating protection of the uninterrupted power source of the present invention.As shown in Fig. 2 In step sl, first by the main path switch device of at least one circuitry phase of uninterrupted power source and its corresponding bypass switching device It is arranged on same radiator.In step s 2, a temperature detection device is arranged on described radiator and is dissipated with detecting Hot device temperature.Preferably, described temperature detection device is arranged on described radiator and is located at described main path switch device and it is right Position between the described bypass switching device answered.Those skilled in the art know, for single-phase and three-phase uninterrupted power supply, dissipate The setting of hot device and temperature detection device is referred to previous embodiment execution, and here is just not repeated.
In step s3, whether the mode of operation judging described uninterrupted power source first is inverter mode.Art technology Personnel are familiar with the decision method of the mode of operation of multiple each circuitry phases to uninterrupted power source.For example can be by detection output electricity Stream, voltage are judging etc..Here, those skilled in the art can adopt any of mode of operation decision method.When sentencing When determining uninterrupted power source and being operated in inverter mode, execution step S4, using the overtemperature protection point of described main path switch device as institute State at least one circuitry phase corresponding overtemperature protection point.When judging that uninterrupted power source is not operated in inverter mode, now give tacit consent to Uninterrupted power source is operated in bypass mode, therefore execution step S5, using the overtemperature protection point of described bypass switching device as institute State at least one circuitry phase corresponding overtemperature protection point.
In step s 6, judge whether described radiator temperature is higher than the corresponding overtemperature protection of described at least one circuitry phase Point.If now radiator temperature is less than or equal to the overtemperature protection point of this circuitry phase, the working properly of uninterrupted power source is described, Now need execution step S7, maintain the current operating state of uninterrupted power source.Here, maintaining the work at present shape of uninterrupted power source State refers to, keeps the mode of operation of uninterrupted power source, output current, output voltage are all constant.If now radiator temperature is high In the overtemperature protection point of this circuitry phase, illustrating that uninterrupted power source work there occurs needs execution step S8 extremely, judges now described Whether at least one circuitry phase corresponding overtemperature protection point is the overtemperature protection point of described bypass switching device.If it is, explanation is not Uninterruptible power is operated in bypass mode, and occurs abnormal, now needs execution step S9, closes described bypass based on user setup Switching device makes uninterrupted power source power-off, or maintains uninterrupted power source to continue work in abnormal cases based on user setup Make.If it is not, explanation uninterrupted power source is operated in inverter mode, and occur abnormal, now need execution step S10, by institute The mode of operation stating uninterrupted power source is switched to bypass mode and the overtemperature protection point of described bypass switching device is arranged to institute State at least one circuitry phase corresponding overtemperature protection point.Now uninterrupted power source is operated in bypass mode.In an embodiment, continue When uninterrupted power source is operated in bypass mode, whether radiator temperature is also higher than the overtemperature protection of bypass switching device for detection Point, therefore after execution of step S10, need to return execution step S6.Due under normal circumstances, the overheated guarantor of bypass switching device Shield point be slightly above main path switch device an overtemperature protection point, therefore uninterrupted power source from inverter mode be switched to bypass mode with Afterwards, generally can be with normal work.
Fig. 3 is the flow chart of the 3rd embodiment of the method for excessive heating protection of the uninterrupted power source of the present invention.In the present embodiment In, uninterrupted power source can be operated in inverter mode, bypass mode, ECO pattern or from aging mode.
As shown in figure 3, in step sl, first by the main path switch device of at least one circuitry phase of uninterrupted power source and its Corresponding bypass switching device is arranged on same radiator.In step s 2, a temperature detection device is arranged on institute State on radiator to detect radiator temperature.Preferably, described temperature detection device is arranged on described radiator positioned at described Position between main path switch device and its corresponding described bypass switching device.Those skilled in the art know, for single-phase With three-phase uninterrupted power supply, the setting of radiator and temperature detection device is referred to previous embodiment execution, and here is just no longer Tire out and state.
In step s3, whether the mode of operation judging described uninterrupted power source first is inverter mode.Art technology Personnel are familiar with the decision method of the mode of operation of multiple each circuitry phases to uninterrupted power source.For example can be by detection output electricity Stream, voltage are judging etc..Here, those skilled in the art can adopt any of mode of operation decision method.When sentencing When determining uninterrupted power source and being operated in inverter mode, execution step S4, using the overtemperature protection point of described main path switch device as institute State at least one circuitry phase corresponding overtemperature protection point.When judging that uninterrupted power source is not operated in inverter mode, execution step S13, judges whether the mode of operation of described uninterrupted power source is bypass mode or ECO pattern, if it does, execution step S14, using the overtemperature protection point of described bypass switching device as the corresponding overtemperature protection point of described at least one circuitry phase.If no Execution step S15 if being, judges that the mode of operation of described uninterrupted power source is from aging mode and to arrange from aging mode mistake Thermal protection point is the corresponding overtemperature protection point of described at least one circuitry phase.
In step s 6, judge whether described radiator temperature is higher than the corresponding overtemperature protection of described at least one circuitry phase Point.If now radiator temperature is less than or equal to the overtemperature protection point of this circuitry phase, the working properly of uninterrupted power source is described, Now need execution step S7, maintain the current operating state of uninterrupted power source.If now radiator temperature is higher than this circuitry phase Overtemperature protection point, illustrate uninterrupted power source work there occurs abnormal need execution step S8, judge that now described at least one is mutually electric Whether the corresponding overtemperature protection in road point is from aging mode overtemperature protection point.If it is, explanation uninterrupted power source now works From aging mode, main road and bypass are all in work, and occur abnormal.Now, answer execution step S9, closed according to user setup Described bypass switching device and described main path switch device or the work at present maintaining described uninterrupted power source according to user setup State.If do not known, execution step S10, judge the corresponding overtemperature protection point of now described at least one circuitry phase whether as described The overtemperature protection point of bypass switching device.If it is, explanation uninterrupted power source is operated in bypass mode, and occur abnormal, now Need execution step S11, described bypass switching device is closed based on user setup and makes uninterrupted power source power-off, or be based on User setup maintains uninterrupted power source to work in abnormal cases.If it is not, explanation uninterrupted power source is operated in inversion Pattern, and occur abnormal, now need execution step S12, the mode of operation of described uninterrupted power source is switched to bypass mode And by the overtemperature protection point of described bypass switching device be arranged to described at least one circuitry phase corresponding overtemperature protection point.Now not Uninterruptible power is operated in bypass mode.In an embodiment, continue detection when uninterrupted power source is operated in bypass mode, radiating Whether device temperature is also higher than the overtemperature protection point of bypass switching device, therefore after execution of step S12, need to return execution step S6.Because under normal circumstances, the overtemperature protection point of bypass switching device is slightly above the overtemperature protection point of main path switch device, therefore After uninterrupted power source is switched to bypass mode from inverter mode, generally can be with normal work.
