Embodiment Construction

[0013] The present invention will be described in further detail below.

[0014] Under normal conditions, the test is carried out under no load, 50% rated load and 100% rated load. Specifically include the following steps:

[0015] Test waveform:

[0016] In the no-load and full-load states, observe whether the waveform is normal, and use a distortion measuring instrument to measure the distortion of the output voltage waveform. Under normal working conditions, connect a resistive load and use a distortion meter to measure the relative content of the total harmonics of the output voltage waveform, which should meet the requirements specified by the product, generally less than 5%.

[0017] Test frequency:

[0018] The frequency of the output voltage can be observed with an oscilloscope and measured with a "power disturbance analyzer". When the accuracy of the UPS output frequency is synchronized with the alternating current, it can reach ±0.2%.

[0019] Test output voltag...

Abstract

The present invention relates to a testing method of UPS performance, especially relates to a testing method of mesomeric state of UPS. The testing method of UPS mesomeric state is executed in normal state and states of empty load, 50% of rated load and 100% of rated load, and comprises the steps of waveform testing, frequency testing, output voltage testing and UPS efficiency testing. The adopted technical settling plan totally settles the problem of efficiency shortage when UPS is executed with mesomeric state testing currently and remarkably increases the testing efficiency of mesomeric state of UPS.

Description

technical field [0001] The invention relates to a test method for UPS performance, in particular to a UPS steady-state test method. Background technique [0002] In order to test the performance of the UPS, a steady state test is usually performed on the UPS. The steady-state test is to test the phase voltage, line voltage, no-load loss, power factor, efficiency, output voltage waveform, distortion and output voltage of the input and output terminals under no-load, 50% rated load and 100% rated load conditions frequency etc. However, there is no complete scheme and standard for the current method of steady-state testing of UPS, so the steady-state testing of UPS is inefficient. Contents of the invention [0003] The purpose of the present invention is to solve the above-mentioned problem of lack of efficiency in the steady-state test of UPS, and provide a very high-efficiency UPS steady-state test method. [0004] Achieving the technical solution of the object of the pr...
