发电机引出线回路及分支回路封闭母线设计

减少接地故障避免相间短路离相封闭母线因有外壳保护可消除外界潮气灰尘以及外物引起的接地故障母线采用分相封闭也杜绝相间短路的发生。消除钢结构发热离相封闭母线采用外壳屏蔽可从根本上解决钢结构感应发热的问题。减少相间短路电动力由于外壳上涡流和环流的双重屏蔽作用使相间导体所受的短路电动力大为降低。封闭母线由工厂成套生产质量有保证运行维护工作量小施工安装简便而且不需设置网栏简化了对土建的要求。

Design on enclosed bus of circuit and branch circuit of generator lead - out wire

Owing to outer shell protect, isolated - phase enclosed bus can eliminate outside dust and moisture, and grounding fault caused by foreign object, bus using phase separation eloesd type can preclude interphase short circuit. Isolated - phase enclosed bus u- sing clad shielding can fundamentally solve the problem of induction heating for steel structure. Because of double shielding of eddy and circulation current in shell, short - circuit electromotive force is reduced greatly. Enclosed bus is complete produced by factory, quality assured, small amount of maintenance, simple installment construction, simplified civil engineering requirements without net pen.
