800kV罐式断路器液压机构渗油的分析及对策

结合一起800 kV罐式断路器液压机构渗油缺陷,认真分析机构组装工艺,并对机构零部件进行了检查测试,发现连接套设计公差偏大、现场安装方法不当是引发缺陷的根本原因。通过重新设计加工连接套、改进现场安装方法,彻底消除了机构存在的安全隐患,为后续800 kV罐式断路器安全运行奠定了基础。

Analysis and Countermeasures to Oil Leakage Fault of 800 kV Pot Breakers Hydraulic Mechanism

Combined with the 800 kV pot breaker hydraulic mechanism oil seepage fault,the earnest analysis hydraulic mechanism assembles a craft,carried on a check test to hydraulic mechanism spare parts,discover conjunction parts tolerance bigger and installing method inaccuracy is the root reason that cause failures.Pass to re-design the conjunction parts and improvement to install a method,complete elimination the security risk exists for follow-up to 800 kV pot breaker went into operation basis.
