摘要

在高压直流输电系统中

换流阀是直流换流站的核心设备之一

它的工作性能直接关系到直流系统的安全稳定运行

对其进行定期试验能及时检验换流阀的健康状况。本文基于换流阀保护性触发原理和开展保护性触发试验的工作原理

阐述晶闸管保护性触发告警的处理原则

结合检修试验中遇到问题提出有关检修维护建议

对以后换流阀的检修、试验提供借鉴。

Abstract

In HVDC system

the converter valve is one of the core equipments of the DC converter station. Its performance is directly related to the safe and stable running of DC system. Regular tests can verify the health of the converter valve in time. In this paper

based on the theory of protective firing of the valve and the working principle of the protective firing test

the fault handling principle of a thyristor protective firing alarm is expounded. Finally

in combination with some problems encountered during the test

suggestions for maintenance are proposed

which can provide references for the maintenance and test of the valve.
