摘　　要：随着能源需求量的逐年扩大和采煤机械自动化程度的提高,现场对供电的可靠性和设备的容量提出了更高的要求。针对目前馈电开关和组合开关的不足,设计了便于集中控制的多回路组合馈电开关,节省了空间和供电线路,减少了重复接线,因此减少了事故隐患,解决了井下因为某一支路发生故障而导致整个供电回路出现停电现象。With the increase of energy demand and the improvement of the automation of coal mining machinery, the field has put forward higher requirements for the reliability of power supply and the capacity of equipment. In view of the deficiency of current feed switches and combined switches, a multiple circuit combined feed switch for centralized control was designed. The utility model saved space and power supply lines, reduced repeated wiring, reduced accident hidden trouble, and solved the problem of power failure in the whole power supply circuit due to a fault of a branch.
