高压真空接触器三相同期度测试仪的设计

Design of three phase voltage measurement instrument for high voltage vacuum contactor

设计的测试仪能测出高压真空接触器三相同期度,保障了接触器合、分闸同期调整到位,可避免因真空管触头粘连或缺相带来的事故。

the design of the test instrument can measure the high voltage vacuum contactor three phase of the same period of time, which ensure the contactor, brake synchronism adjustment in place, can avoid the accident caused by vacuum tube contact adhesion or lack of phase.
