浅议隔离开关的应用及故障处理

Shallow Talk about the Application of Isolated Switch and Fault Handling

牵引变电所是铁路供电系统中实现电能转换的枢纽。高压隔离开关是牵引变电所中重要的高压开关电器,也是应用范围很广的一次设备。随着综合远动系统的广泛应用,有人值班变配电站逐渐向无人变配电站过渡,值班方式的改进必然带来了检修方式的改变,即逐渐由"定期修"向"状态修"的转变。然而,"状态修"的检修周期在逐渐延长,一旦使用中的高压隔离开关发生故障,将直接影响整个牵引供电系统和铁路行车的安全。从高压隔离开关的作用、运行中常见的故障及其产生原因、检修办法等方面进行了阐述,希望对现场相关设备的维护起到一定的指导意义。

Traction substation is the railway power supply system to achieve power conversion hub. The high-voltage switch is the important high-voltage switch in the traction substation, and is also a widely used equipment.. With the extensive application of integrated telecontrol system, one on duty substation gradually into an empty variable power distribution transition, improvement on duty will inevitably bring about the changes in maintenance mode, and gradually by the “regular” change to “state”. However, the maintenance cycle of the “status repair” gradually extended, once the high voltage isolated switch faults occur, it will directly affect the whole traction power supply system and railway traffic safety.. High-voltage isolating switches from the role, in the operation of the common fault and its causes and repair methods are described, want to have certain guiding significance to the field equipment maintenance.
