多绕组变压器副边公共接地母线的设计选型

Design Selection for Common Main Grounding Line in Secondary Side of Multi-winding Transformer

多绕组变压器广泛应用于大型起重机、隧道掘进机等大型机械设备上。介绍了变压器副边公共接地母线的设计选型依据,提供了一种多绕组变压器副边公共接地母线的设计选型方法,能够有效指导多绕组变压器的副边公共接地母线设计。

The multi-winding transformer is widely used in large mechanical equipment such as large crane and tun-neling machine. Design selection basis of common main grounding line in secondary side of multi-winding transformer is in-troduced, and a selection method is proposed for effective guides to the design of this common main grounding line .
