高压隔离开关的常见故障及处理

高压隔离开关是电力系统中使用量最大、应用范围最广的高压电器设备。但是,高压隔离开关长期处于合闸状态而较少进行操作,又是不太受制造和使用部门重视的电器设备。制造厂往往将高压隔离开关作为与断路器配套的一种附加产品进行生产,其性能和质量很难予以保证;运行部门也忽略了对高压隔离开关的管理,尤其是检修管理,普遍存在长期失修的现象,尤其是母线隔离开关基本不检修。

Common Failures and Treatment Measures of High-voltage Isolation Switch

The high-voltage isolation switch is the high-voltage electrical equipment with largest use and widest range of application in the power system.However,the high-voltage isolation switch is the electrical equipment which is in long-term closed state and less to operate,is not paid attention to by the departments of the manufacture and user.Factories regard high-voltage isolation switch as a kind of add-on product which is matched with breaker to produce,and its performance and quality is difficult to be guaranteed;running departments also ignore the management of high-voltage isolation switch,especially maintenance management,and it exists in the phenomenon of long-term disrepair,especially the busbar disconnectors is not overhauled basically.
