注塑機在正常生產(chǎn)時(shí)，1年之中發(fā)生2次接觸器著(zhù)火，每次都用火器滅火，損失都上千元，接觸器都是品牌，型號1810都在額定電壓和電流下工作，并且都是從接觸器內部先引燃，接觸器線(xiàn)圈電壓是AC220V,線(xiàn)圈二端并接一個(gè)QS21150(火花消除器)，就是控制發(fā)熱圈溫度，平時(shí)巡查測接觸器溫度不高，今天就著(zhù)火，希望大家一起來(lái)分析原因，多謝。

看現場(chǎng)，起明火的是布線(xiàn)槽，建議采用阻燃型布線(xiàn)槽�；鹗菑南旅嬉鸬�，品牌的交流接觸器是不會(huì )起明火的，你可試一下，導線(xiàn)用高溫導線(xiàn)，定期檢查一下。
