Electrical property measuring apparatus

Abstract

The invention discloses an electrical property measuring apparatus. The cabinet of the electrical property measuring apparatus comprises a control module, a voltage and current waveform sampling module and an electronic starting switch. The electronic starting switch and the voltage and current waveform sampling module is synchronously controlled, so that the starting transient electrical property of all kinds of electronic equipment can be measured conveniently. The electrical property measuring apparatus can measure the input static electrical property, output static electrical property, transient electrical property, timing sequence electrical property, protection electrical property, pulse electrical property and the like of all kinds of electric equipment, and has the advantages of complete test functions, low cost and small size.

Description

【Technical field】 [0001] The invention relates to the field of electrical performance testing, in particular to an electrical performance measuring instrument for comprehensively measuring electrical parameters of electric appliances. 【Background technique】 [0002] Electrical appliances (such as power supplies, household appliances, electric tools, lighting appliances, etc.) are widely used in life. The electrical parameters of electrical appliances are one of the main indicators to characterize the performance of electrical appliances. On the one hand, some high-demand electrical appliances need to make more complex electrical performance measurements, such as LED drivers, and also need to measure startup characteristics, sequence time, protection characteristics, pulse signals, etc. At present, the general electrical parameter measuring instrument is limited to the measurement of basic electrical parameters such as voltage, current, power, etc., and cannot meet the requir...

AI Technical Summary

Problems solved by technology

At present, the general electrical parameter measuring instrument is limited to the measurement of basic electrical parameters such as voltage, current, power, etc., and cannot meet the requirements of comprehensive measurement. Another method is to assemble the instruments and equipment for testing various parameters together to measure multiple performances of electrical appliances. requirements, but its shortcomings are that it requires a lot of equipment, the operation is cumbersome, the cost is expensive, and it takes up a lot of space

And even if the instruments and equipment with multiple parameters are combined together, it is still very difficult to measure the start-up transient electrical performance of various electrical appliances such as inverter power supplies, LED drivers, lighting appliances, and home appliances.
