摘要
本文结合沈阳至铁岭城际铁路工程设计,对中压供电系统的保护配置进行研究分析,并给出进出线开关、母联开关、整流机组馈线开关、配电变压器馈线开关等中压供电系统继电保护定值整定的计算方法,供其他类似工程参考。
With connection to the design of Shenyang-Tieling intercity railway project,the paper studies and analyzes the protection configuration of medium voltage power supply system,puts forward the calculation methods for setting values for relay protection of medium voltage power supply systems such as:incoming and outgoing line switches,bus bar switches,rectifier set feeder switches and feeder switches of distribution transformer,providing references for other similar projects in the future.
