      1. 上海人民電氣有限公司介紹漏電斷路器的原理作用

        1、漏電斷路器的原理是當(dāng)短路時,大電流(一般10至12倍)產(chǎn)生的磁場克服反力彈簧,脫扣器拉動操作機構(gòu)動作,開關(guān)瞬時跳閘。當(dāng)過載時,電流變大,發(fā)熱量加劇,雙金屬片變形到一定程度推動機構(gòu)動作(電流越大,動作時間越短)。

        2、作用是切斷和接通負(fù)荷電路,以及切斷故障電路,防止事故擴大,保證安全運行。而高壓斷路器要開斷1500V,電流為1500-2000A的電弧,這些電弧可拉長至2m仍然繼續(xù)燃燒不熄滅。故滅弧是高壓斷路器必須解決的問題。
