摘要
文章对低压备自投功能的原理进行介绍,并对工厂实际中低压配电系统的备自投回路以及其进线开关和联络开关的控制回路进行详细分析,深刻理解其备自投的动作原理和各种联锁条件,解决实际调试过程中遇到的问题的同时,对调试过程进行总结,为今后更好完成同类工作积累经验。
The principle of low-voltage backup automatic switch function was introduced.The backup automatic switch circuit of the actual medium low voltage distribution system of the factory,the control circuit of its incoming line switch,and contact switch were analyzed.A deep understanding of the operation principle and various interlocking conditions of the standby automatic switching were introduced.While solving the problems encountered in the actual debugging process,the debugging process was summarized to accumulate experience for better completing similar work in the future.
