摘要
针对目前通信枢纽低压配电系统所广为采用多系统供电结构、负载末端切换以及TN-S接地方式,论述工程设计中值得注意的配电系统接地方式及末端切换转换开关的选择问题。并提出了相应的处理方法。
According to the present communication hub of low voltage distribution system which is widely used by many systems, power supply structure, load switch and TN-at the end of grounding method, the paper discusses the S attention in engineering design of the power distribution system grounded way and end switch choice problem, and supposes the corresponding treatment method.
