500kV交流输变电工程启动调试中断路器分合分试验的分析

在500kV交流输变电工程的建设完成后,需要对其进行启动调试,同时测试的次数要不少于3次的单分单和冲击合闸试验.但是在进行完这项试验后,为了安全考虑要在空载线路上进行分和分试验.本文主要根据实际经验分析出了在某些情况下,进行分和分试验存在一定的风险性,同时结合理论知识提出降低或去除这种风险的方法.

Start debugging in 500 kv ac power transmission and transformation project circuit breaker points and test analysis

after completion of the construction of 500 kv ac power transmission and transformation project, it is necessary to start the debugging and testing at the same time the number of times or less than 3 times of single points and impact closing test. But after finish the experiment was carried out, for the sake of safety to points and test on the racing circuit. In this paper, based on the analysis of practical experience in some cases, there are some points and experiment of the risks, combined with theoretical knowledge at the same time put forward the method to reduce or eliminate the risk.
