Description

触点式熔断器
本实用新型涉及熔断器,尤其是一种触点式熔断器。
目前,大容量电器设备主要由两相熔断器进行保护,也就是其中任何一相烧损,控制线路就能切断电源,达到保护电气设备的目的。但是如果电气设备外接线路的熔断器烧损,动力设备仍然运行,所以易被烧坏。
本实用新型的目的在于提供一种触点式熔断器,将其置于动力设备的外接线路,当其烧损时也能切断电源达到保护电气设备的目的。
本实用新型的技术方案:两个接线柱触点上方各置有与其相接触的动触头,两个动触头间经连杆相互导通,连杆支撑有顶柱,顶柱下接有压簧,压簧下接有拉线。
本实用新型的优点:由于采用本实用新型使得更能有效地保护动力设备。
结合附图叙述本实用新型的实施例。
图1本实用新型的主视结构示意图;
图2本实用新型的侧视结构示意图;
图3本实用新型应用时的电路原理图。
当本实用新型即R1熔断器内熔丝过热烧损时,将拉线5烧断,由于压簧4的作用,顶柱3向上串动带动动触头1与接线柱2上的触点分离使由电线6、接线柱2、动触头1、连杆7构成的电路通路断开,从而使熔断器R2、R3回路断开,达到保护动力设备的目的。
