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。

Abstract

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.
