Cable AC Withstand Voltage Test System Based on Oscillating Wave Principle

对振荡波交流耐压的原理和特点进行了分析,并利用PSPICE软件对所设计的主电路中的元件参数进行了仿真分析。在此基础上,对整个系统进行了搭建,并对保护电路和系统的试验结果进行了测试。电路的测试分析结果表明,所设计的电路不仅能够产生良好的试验波形,而且还有很好的过流保护和过压保护功能。

At first, the principle and characteristics of oscillating wave AC withstand voltage method are described in detail, and the parameters of components in the designed main circuit are simulated and analyzed by PSPICE software. Thereupon, the whole system is set up, and the experimental results of protective circuit and system are tested. The test results show that this designed circuit not only generates good oscillating wave, but also possesses good over current and overvoltage protection function.
