产品介绍

在使用时继电器必须定期进行检査维护,检査时按下列项目进行:

4.2.1继电器线圈外加电压(流)不得超过规定数据;电压线圈不得超过线圈额定电压的105。/。;电流线圈不 得超过线圈额定电流。

4.2.2衔铁紧密地与铁芯接触,衔铁与铁芯接触面有尘埃或油垢附着时可用汽油清洗干净。

4.2.3磷铜片有机械磨损时必须更换。同时必须注意磷铜片是否紧密地贴在衔铁上,不得弹起。

4.2.4触头表面烧坏时,必须及时清理或调换新触头,清洗时不允许采用砂纸,可以用汽油清洗或用细锉 刀修理,在修理时银层应尽量少去一些,并不应改变触头的曲率半径。

4.2.5继电器触头的超行程、断幵距离,压力等如不符合表4数据时应调整达到。
