一起典型的GIS刀闸机构分闸位固死的故障处理及二次原理解析

Breaker Typical GIS with the Agency Break-brake Principle of Fault Handling and Secondary of the Fixed Die Parsing

刀闸机构是GIS操作的重要部件,不能电动分合的故障时有发生,而产生故障的原因也有很多方面,此次缺陷原因非机械故障、非电机控制回路和电机转动回路的故障,是由电制动回路故障引起。下文将结合我局某变电站一起GIS刀闸机构分闸位固死故障为例,从多个角度寻找原因,最后再采取有效措施从根本上解决了问题,并提出了相关经验总结。

Isolating switch is an important part of a GIS operations,and cannot be electric points of failure occurs frequently,and the causes of failure also have a lot of ways,the defect reason not mechanical failure,motor control circuit and turn the circuit fault,is caused by electric braking circuit fault. Below will inform a substation combine with GIS isolating switch break-brake solid die failure as an example,from various angles to find the reason,and then take effective measures to fundamentally solve the problem,and puts forward the relevant experience.
