电枢和换向器是焊接发电机中两个非常重要的部件,它在工作中所起的作用是,在旋转状态下产生感应电动势,并且以直流电的形式输送到机体外部,为焊接电弧提供直流电能。由于电枢和换向器本身结构的原因,所以,当这两个部件出现短路、断路故障后,必须采用特殊的方法才能检查出故障发生的具体部位,然后再排除故障。下面就将这两个部件在出现故障时的检查方法介绍如下。 Armature and commutator are two very important parts of welding generator. They work in the role of generating induced electromotive force in the rotating state and delivering it to the outside of the body in the form of direct current, so as to provide the welding arc DC power. Due to the structure of the armature and the commutator itself, when these two components are short-circuited or open-circuited, a special method must be used to check the specific location of the fault and then eliminate the fault. The following will check these two components in the event of failure as follows.
