某电磁继电器失效分析及改进

Failure Analysis and Improvement of Electromagnetic Relay

针对某继电器在使用过程中出现的线圈开路现象,分析了线圈开路的原因是由于引出线与漆包线之间虚焊。针对这一现象,提出了相应的耐振设计方法,并且正确的安装也可以预防继电器早期失效。

Aiming at the coil-open-circuited of electromagnetic relay, the main reasons for the failure of the electromagnetic relay is the the dry joint between lead-out wire and enamel wire. The shockproof design method is put forward on this phenomenon. And then the proper installation can prevent the early failure of electromagnetic relay.
