摘　　要：结合两起800 kV罐式断路器液压机构缺陷,通过介绍机构工作原理,重点分析了检修工艺执行情况,找出液压油中空气含量大是造成设备缺陷的根本原因,采用抽真空注油的办法消除了缺陷,并制定了严格执行检修工艺、优化机构设计、开展油液化验等防范措施。Taking two defects in the hydraulic mechanism of a 800 kV pot-type breaker for example, the working principle of the mechanism is introduced, and the implementation of the check and repair process is analyzed in detail. The defects are found to be caused by larger air content in hydraulic oil. As a result, vacuumizing and oil feeding are adopted to eliminate the defect. In addition, some countermeasures are put forward to prevent this kind of defects, such as strictly implementing the check and repair process,optimizing the design of the hydraulic mechanism, and testing oil, etc.
