Static Potential Measurement on the Shield of Vacuum Interrupters
摘要
对中间封装式和瓷柱支撑式两种主屏蔽罩安装方式的真空灭弧室中主屏蔽罩电位进行了静态工频测试
找出了为什么中封式真空灭弧室装入整机后并不比瓷柱式真空灭弧室耐压特性优越的原因
指出在真空断路器设计中
尤其在高电压等级下
真空灭弧室的均压问题应与整机总体设计同时考虑。
Abstract
This Paper measures the static potential in vapour shields of two fixing methods-middle fixed type and ceramic supporters fixed type.It finds out the reasons Thy the middle fixed type is not better than the ceramic fixed one in voltage characteristic when it is fixed into the switchge-ar
It points out that it is.necessary to co.mbine the design of vacuum interrupter with switchgear
