介绍了研制的一套用光电法在高电位端测量试品直流高压下泄漏电流的装置。该装置量程范围为8～800μA,双极性信号转换,电池供电,功耗仅100mW。转换信号在低压侧进行微机处理后显示或记录。与传统的测量方法相比,该装置具有使用方便、抗干扰能力强、测试准确、线路简单和体积小的优点。该装置稍加改进,即可进行其它高电位端的电压及小电流的检测。
A set of developed a set of photoelectric method in the high potential side of the test sample DC high voltage leakage current device. The device range of 8 ~ 800μA, bipolar signal conversion, battery-powered, power consumption is only 100mW. The conversion signal is displayed or recorded on the low pressure side after computer processing. Compared with the traditional measurement methods, the device has the advantages of convenient use, strong anti-interference ability, accurate test, simple circuit and small size. The device slightly improved, you can carry out the other high voltage side of the voltage and small current detection.
