矿用隔爆型磁力起动器是煤矿井下用途最广、用量最大的电气设备之一。由于工作条件恶劣,操作相当频繁,制造质量与维护水平又各不相同,因此,出现的故障也相对较多。由于它用量大,所以它的故障不仅关系到被控制电动机的使用寿命,关系到煤炭生产效率,而且也关系到设备安全和人身安全,千万不能忽视。起动器质量好坏与设计 Mining flameproof magnetic starter is the most widely used coal mine, the largest amount of electrical equipment. Due to poor working conditions, the operation is quite frequent, the quality of manufacture and the level of maintenance are different, therefore, there are relatively many failures. Because of its large amount, so its failure is not only related to the life of the motor being controlled, relates to the coal production efficiency, but also relates to equipment safety and personal safety, must not be neglected. Starter quality is good or bad and design
