摘要

受设备容量的限制以及传统试验方法的局限

实验室很难对具有较长时间常数的特高压断路器进行非对称电流开断试验。笔者分析了该试验的原理

提出了一种新的电流补偿的试验方法。通过计算分析

论证了试验方法的等价性。1 100 kV断路器非对称电流开断试验采用了该试验方法

并顺利完成了多台产品的试验。这种试验方法还进行了推广应用

成功地完成了发电机断路器的非对称电流开断试验。

Abstract

Due to the limitations of equipment capacity and traditional test method

it is difficult for laboratory to carry out the asymmetric current breaking test for UHV circuit breaker with long time constant.This paper analyzed the test principle

and proposed a new current compensation test method.The equivalence of the test method was proved by calculation and analysis.This test method was successfully used in asymmetric current breaking test of several 1 100 kV circuit breakers.Moreover

it also used in asymmetric current breaking test of GCB.
