因为启动是接点的颤动,因之电机直接启动时电流量挺大,因而易导致接触器主断路器的熔焊。经剖析主断路器颤动缘故有二种,一要因为吸合回路中二级管D,和电阻器R松动,故在触碰吸合时因为阻尼振动的危害,导致该回路时通时断;二是因为接触器启动时与终止时,电磁线圈两边会造成相当于高的操作过压易热击穿D2,续流二极管D2热击穿后开路,使接触器不可以保持而释放出来,其常闭触点1JC又再次闭合,操作者并不是在极短的時间内将启动按键QA释放出来,相对见电机未启动而反复按起动按键,因此导致反复吸合,反复释放出来而造成颤动,因而,在启动比较易造成接触器旁边两相主断路器熔焊,使电机处在两相电启动情况,即便热继电器动作,不因主断路器熔焊没法断掉主回路,故直到电机凭阻绝缘层损坏,热击穿电源电路后,控制开关才跳开。

改进方法:在自制无声运行控制板时,交流接触器厂家要不断完善加工工艺。避免虚焊、连接头松动是彻底能够保证的,续流二极管D2,即便采用击穿电压较高的,但因为元器件品质不同,启动一瞬间的操作过压又较高,会造成热击穿毁坏而开路,导致两相熔焊安全事故。再加现阶段电机维护大多数仍采用热继电器。漏电保护开关虽知过压保护作用,但通常只有用以路线过压保护而不可以与电机负载特点相辅,故熔焊时不可以合理地维护电机,因此,交流接触器无声运行时,非常是操作经常或容积较大的场所,必需特别注意所述的维护状况。
