摘要
在分散式供电、中压双环网接线方式下,对继电保护和安全自动装置的设置进行分析,并说明电流速断、过电流和备自投装置的具体配合关系。
In the connection mode of distributed power supply and medium voltage double - looped network, the configuration of relay protection and safety automatic devices is analyzed, and the detailed cooperating relationship among current instantaneous break, over -current and spare power automatic switch device is also presented.
