摘要
开关压力闭锁回路对开关的操作有重要影响,当开关本体内SF_6压力低于正常值时,压力闭锁回路将闭锁对开关进行的操作,文章以电网中使用较多的西门子、ABB等开关为例,分析了它们的压力闭锁回路在获取电源时存在的问题,并针对这些问题提出了相应的解决方法。
The blocking circuit of switch pressure has important influence for switching operation, when the SF6 pressure in switch body is below normal pressure,blocking circuit will block the switching operation. The paper analyzed the existent problems for getting power source of pressure blocking circuit taken as example of the switches from Siemens and ABB,and put forward the corresponding solution method according to these problems.
