隔爆型低压大容量电机接线盒的引线结构设计

Design on the Connection and Wiring in the Terminal Box Used for Large-size Flameproof Low-voltage Motor

通过对各种电机接线盒引线结构的分析对比,提出了一种新颖的电机引线结构:用一个接线螺栓压接两根引接线并且接线螺栓采用分开加工,解决了隔爆型低压大容量电机定子电流大及接线螺栓加工难的难题,为隔爆型低压大容量电机的开发奠定了基础。

By comparison of the structures of different terminal boxes, a newly structure for leading wiring for motor put forward： two leading fixture wires are clamping connected by one bolt. With this connection method, it is solved the problems of large current in stator for flameprooof low- voltage largesized motor and hardly to machine the wiring bolts.
