国产车辆在出厂时普遍未装设电源总开关(俗称总闸),通常由电源保险丝替代,但其功能有别。部分单位或个人从实用角度出发,一般在车辆电源蓄电池附近增设一电源总闸。现就增设该装置的利弊谈些体会。 一、其利——开启、闭合方便实用 1.当车辆的电路发生短路、断路或搭铁时,电源总保险丝失效而引起的电线冒烟、着火,可及时断开总闸,避免引发更大的故障及事故。 2.当起动继电器失灵,发生起动机电枢“飞车”,可立即关闭总闸,避免烧坏起动机总成。笔者就曾遇此情 Domestic vehicles are generally not installed in the factory when the power switch (commonly known as the main gate), usually replaced by the power fuse, but its function is different. Some units or individuals from a practical point of view, usually in the vehicle power storage battery near the addition of a power gate. Now talk about the pros and cons of adding the device to talk about some experience. First, the Lee - open, closed and convenient and practical 1. When the vehicle’s circuit short circuit, open circuit or the ground, the power fuse failure caused by the wire smoking, fire, the total gate can be promptly opened to avoid causing more Faults and accidents. 2. When the starter relay fails, the starter armature “speed” occurs, you can immediately turn off the total brake, to avoid burning the starter assembly. I have encountered this situation
