过电压保护器是安装在PT柜内，用来保护电气设备免受过电压的影响，可以提高设备的安全可靠性，现在市面上已经有较为完善的过电压型式试验报告了，那么这个报告都需要测试过电压保护器的哪些方面呢？
Overvoltage protector is installed in PT cabinet to protect electrical equipment from the influence of overvoltage, which can improve the safety and reliability of equipment. Now there are more perfect over-voltage type test reports on the market, so what aspects of overvoltage protector need to be tested in this report?
首先要进行的是复合外套外观检查，查看外观有无损坏，
The first thing to do is to check the appearance of the composite coat to see if it is damaged.
接下来进行的就是爬电比距检查、直流参考电压试验、0.75U1ma下泄漏电流试验、工频参考电压试验、持续电流试验、局部放电试验、残压试验、常持续时间电流冲击耐受试验、避雷器外套绝缘耐受试验、封闭实验。
Next, creepage ratio test, DC reference voltage test, leakage current test under 0.75U1ma, power frequency reference voltage test, continuous current test, partial discharge test, residual voltage test, constant duration current shock resistance test, arrester jacket insulation resistance test and closure test are carried out.
最后进行的是机械负荷试验以及工频电压耐受时间特性试验了。
Finally, mechanical load test and power frequency voltage withstand time characteristic test are carried out.
过电压保护器在进行检验的时候就是这些项目了，一只合格的过电压保护器会完美的经受住上面的各种检测与试验。
Overvoltage protectors are these items when they are tested, and a qualified overvoltage protector will perfectly withstand all kinds of tests and tests above.
