Description

一种熔断器式隔离开关
本实用新型涉及一种隔离开关，特别是一种熔断器式隔离开关。
目前在城市电网中，配电变压器低压侧的隔离开关往往是采用单极闸刀加一熔丝座，但是单极闸刀在拉断时要产生大的电弧，容易造成相间短路，损伤人员设备。
本实用新型的目的是提供一种安全可靠、结构简单的熔断器式隔离开关。
本实用新型的技术方案是设计一种熔断器式隔离开关，包括箱体、箱体门、进线桩、出线桩，其特征是：进线桩上接有一动触头，动触头上有消弧罩，出线桩上接一下端刀片，下端刀片由一栅式熔丝连接上端刀片，刀片与箱体门铰接。
本实用新型的优点是安全可靠、操作简单。
下面结合附图及实施例对本实用新型作详细说明，
图1为本实用新型的结构示意图；
图2为本实用新型的A-A剖示图；
图中包括箱体1、箱体门9、进线桩2、出线桩3，其特征是：进线桩2上接有一动触头4，动触头4上有消弧罩5，出线桩3上接一下端刀片6，下端刀片6由一栅式熔丝7连接上端刀片8，刀片与箱体门9铰接。使用时按照下进上出及换栅式熔丝7不带电的原则，进线桩2由导线连至箱体1上端的动触头4，为防止拉合刀片的电弧，动触头4外有一消弧罩5，由于刀片与箱体门9铰接，当箱体门9合上时推动上端刀片8与动触头4接触，发出的电弧有消弧罩5分隔消弧，拉下箱体门9时，带动上端刀片8与动触头4脱离拉断电流，箱体门9拉开时刀片不带电，方便更换栅式熔丝7。
