一种换流阀晶闸管级性能测试仪辅助接线装置的设计
|
摘要
换流阀是高压直流输电系统的核心部件,而晶闸管是保证换流阀正常稳定运行的重要组成部分。为保证换流阀的基本电气性能,需要工作人员例行检查晶闸管级的电气性能。针对常规性能测试仪中存在的耗时长、效率低且具有安全隐患的问题,设计了一种基于换流阀晶闸管级性能测试仪的简易辅助接线装置。设计的装置不仅能够有效解决问题,而且提高了工作效率。
Converter valve is the core component of HVDC transmission system,and thyristor is an important part to ensure the normal and stable operation of converter valve. In order to ensure the basic electrical performance of converter valves,it is necessary for staffto routinely check the electrical performance of thyristor level. Aiming at the problems of timeconsuming,low efficiency and potential safety hazard in conventional performance tester,a simple auxiliary wiring device based on thyristor level performance tester of commutation valve is designed. The designed device cannot only solve the problem effectively,but also improve the working efficiency.
