一起罐式断路器内部放电的故障分析

Fault Analysis of Internal Discharge of Tank Circuit Breaker

针对一起罐式断路器内部放电故障,通过对故障罐式断路器现场解体、试验及返厂解体等各环节进行分析,找出设备内部产生放电故障的原因,并从产品设计、运输安装过程中存在的安全隐患对这一故障的影响进行研究,给出了具体的故障处理方案和产品改进措施,实际应用验证了改进方案的合理性与正确性。

Aiming at an internal discharge fault of tank circuit breaker, this paper analyzed each link of the fault tank circuit breaker onsite collapse, test and disintegration of returning to the factory, to fi nd out the reason of the discharge inside the equipment. From the corner of product design and manufacturing, transportation and installation process in security, this paper researched on the infl uence of the fault, presenting a detailed scheme of fault handling and product improvement. Practical application verifi es the correctness and rationality of the improved scheme.
