Abstract

The present invention relates to a method for testing UPS performance, and especially to a method for dynamically testing UPS. The dynamic testing method of UPS comprises the steps of: abruptly load adding or abruptly load reducing testing step and characteristic switching step, in the step, the phase voltage and frequency in empty load and mesomeric state require to be measured in the abruptly loading adding or abruptly load reducing testing step; abruptly adding the load from 0% to 100% or abruptly reducing the load from 100% to 0% and measuring the output transient voltage of UPS; and determining whether the UPS is qualified. The characteristic switching step uses a storage oscilloscope and a pressure regulator which can simulates the variation of alternating current for testing whether a breaking point exists in power supplying when the alternating current is switched to the inverter in 100% of load. The adopted technical settling plan totally settles the problems of more complication and hard operation in the prior UPS dynamic measuring method thereby increasing the testing efficiency remarkably.

Description

The UPS dynamic testing method
Technical field
The present invention relates to the method for testing of UPS performance, particularly the UPS dynamic testing method.
Background technology
Dynamic test generally is when load changing (generally selecting load by 0%-100% with by 100%-0%), and the variation of test UPS output voltage waveforms is with dynamic perfromance and the energy back path of check UPS.But the UPS dynamic testing method is complicated at present, is unfavorable for operation.
Summary of the invention
The objective of the invention is to solve above-mentioned UPS dynamic testing method complicated, be unfavorable for the shortcoming of operating providing a kind of UPS dynamic testing method simple and easy to operate.
Realize that the object of the invention technical scheme is: a kind of UPS dynamic testing method, comprise impact or anticlimax load testing step and switching characteristic testing procedure, wherein,
Described impact or anticlimax load testing step are:
A, phase voltage and frequency when measuring zero load, stable state with power disturbance analyzer;
B, shock load by 0% to 100% or the anticlimax load by 100% to 0%, measure UPS output transient voltage;
C, judgement: if UPS output transient voltage is between-8%-+10%, and return to stable state in 20ms, then this index of this UPS is qualified; If when UPS output transient voltage exceeded this scope, then this kind UPS was defective;
Described switching characteristic testing procedure is: test with the pressure regulator that storage oscilloscope and energy analog alternating current change, transfer test will carry out under 100% load, when particularly being transformed on the inverter by alternating current, the inverter that is equivalent to UPS loads suddenly, output waveform has in 1~2 cycle ± 10% variation, power supply has or not breakpoint during test conversion, and breakpoint is no more than 20ms.
Further, on line type UPS does not have breakpoint in the described switching characteristic testing procedure, but its waveforms amplitude has transient change, disappears in the semiperiod.
Owing to adopted above-mentioned technical solution, solved fully present UPS dynamic testing method complicated, be unfavorable for the problem of operating having improved test ground efficient significantly.
Embodiment
Below the present invention is described in further detail.
The UPS dynamic testing method comprises impact or anticlimax load testing and two steps of switching characteristic test.
Impact or anticlimax load testing step:
Phase voltage and frequency when measuring zero load, stable state with " power disturbance analyzer " earlier, then shock load by 0% to 100% or the anticlimax load by 100% to 0%, if UPS output transient voltage is between-8%-+10% (can decide according to this index of concrete type), and return to stable state in 20ms, then this index of this UPS is qualified; If when UPS output transient voltage exceeds this scope, will produce bigger surge current, all be totally unfavorable still to load to UPS itself, then this kind UPS just should not select for use.
The switching characteristic testing procedure:
Conversion characteristic when this mainly tests and is transformed into Alternating Current Power Supply or is transformed into inverter power supply by Alternating Current Power Supply by sine wave pulse width modulated (SPWM) inverter power supply.The pressure regulator that need have storage oscilloscope and energy analog alternating current to change during test.
Transfer test will carry out under 100% load, and when particularly being transformed on the SPWM inverter by alternating current, the inverter that is equivalent to UPS loads suddenly, and output waveform may have in 1~2 cycle ± 10% variation.Be exactly the power-off time of load switching time.This test is that power supply has or not breakpoint when detecting conversion, and if any breakpoint, and breakpoint will cause dropout above 20ms.On line type UPS does not generally have breakpoint, but its waveforms amplitude has transient change, requires to disappear in the semiperiod.In addition, because UPS at Alternating Current Power Supply just often, the inverter frequency of operation is to follow the tracks of ac frequency, in case Alternating Current Power Supply interrupts, inverter frequency is controlled by the local oscillator of control circuit fully, and this changes suddenly is randomness, it is relevant with the state that alternating current interrupts preceding momentary status and local oscillator, the transient changing of this frequency control may cause output frequency to change and reach 30%, and a lot of loads can't adapt to this variation.
Above embodiment is only for the usefulness that the present invention is described, but not limitation of the present invention, person skilled in the relevant technique, under the situation that does not break away from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
