矿用隔爆型组合式局部通风机电磁起动器的机械闭锁

Mechanical Lockout of Electric-magnetic Starter for Mine Eaplosion-proof Combined Local Ventilator

在对矿用隔爆型组合式局部通风机电磁起动器的备用启动装置进行维修时,不仅要断开备用启动装置的电源,还应断开工作与备用2套启动装置间的通讯与电气联锁接线。介绍了可以满足这一要求的机械闭锁结构。

During maintance of the standby starte of the electric mechanical starter for mine explosionproof combined local ventilator, not only the power of the standby starter but aslo the electric interlock between the service and standby starter should be cut off. A mechanical lockout system which can meet the need is introduced.
