QC83—80N型可逆磁力起动器(以下简称80N开关)由于结构和线路的特殊性、给加装JDB系列电机综合保护器造成了一定的困准。至今全局在用的一千多台该类开关均未装置电机综保、极不适应安全生产的原则。为此我们组织力量对80N开关加装电机综保工作进行了探讨,现将情况加以介绍,以供参考。一、可行性探讨 80N开关为防止两接触器同时吸合,开关内设有机械和电器闭锁。因此具有接线和
QC83-80N reversible magnetic starter (hereinafter referred to as the 80N switch) due to the particularity of the structure and the line, to install JDB series motor integrated protector caused some difficulties. Up to now, more than one thousand such switches in use in the world have not been fitted with motorized comprehensive insurance and are extremely unmanaged to the principle of safety in production. To this end, we organize forces on the 80N switch installed motor protection work were discussed, the situation is introduced for reference. First, the feasibility of 80N switch to prevent the two contacts simultaneously pull the switch with mechanical and electrical locking. So with wiring and
