摘要
以CSB-21A为例,介绍110kV进线备用电源自动投切装置二次回路的接线原理,在此基础上讨论进线备自投的跳、合闸回路的设计和开关量接入位置等一些需要注意的问题和对策。
In this paper, the secondary circuits of the 110 kV input reserve power auto-switch device （LBTZ） were introduced in details by using CSB-21A as an instance. Some practical application problems, such as the design of the trip-reclosure circuits and the selection of the relays location, were pointed out. Finally, the corresponding solutions were proposed. These measures are useful for improving the reliability of power supplying.
