摘　　要：高压电力电缆作为电网中电力运输的载体,其性能良好对保证电网安全稳定运行具有重要意义。为验证出厂电缆产品其绝缘系统负荷能力,对成品电缆系统及其附件进行高负荷工况模拟,进行相应的电气等类型试验。本文主要对其中局部放电、热循环电压、介质损耗角正切、雷电冲击及工频交流耐压试验原理、方法进行介绍。High voltage power cable is the carrier of electric power transportation in the power grid,its good performance is of great significance to ensure the safe and stable operation of the power grid.High voltage power cable is the carrier of electric power transportation in the power grid,its good performance is of great significance to ensure the safe and stable operation of the power grid.In order to verify the load capacity of the insulation system of the outgoing cable products,the finished cable system and its accessories are simulated under high load conditions,and the corresponding electrical and other types of tests are carried out.This paper mainly introduces the principle and method of partial discharge,thermal cycle voltage,dielectric loss Angle tangent,lightning impulse and power frequency AC voltage withstand test.
