摘　　要：本文介绍用三个小电流晶闸管和一个继电器把普通接触器变换成无弧接触器。电路简单,造价低。因无电弧,故触点寿命长,可试用于易爆场合。This article introduces how to convert an ordinary contactor to a non-arc contactor by using three small current SCRs and a relay. The circuit is sample and its price is low. This contactor has no arc, so its contact is long life, and it can be tried to use in easy-bomb form.

关 键 词：无弧接触器 接触器 触点
