1 10kV配电网环网供电简要分析
10kV配电网环网供电是现代一种先进的供电方式,在其供电过程中,采用电压-延时方式进行供电控制、在实际的供电运行过程中,断路器装置供电应用十分关键,当前整个环网处于供电阶段,断路器属于闭合状态。而在线路出现停电状态之后,整个断路装置会做保护状态,打开断路保护装置,实现对整个环网的保护。而实际的10kV配电网环网供电供电过程中,故障区域容易出现二次跳闸现象,实现了对电力故障的有效解决。另外,在正常供电状态下,断路装置能够實现对电源的保护。当一侧电源处于失压状态时,该断路器 即对故障确认进行延时,故障侧相应线路对故障确定并完成闭锁的实际时间即为延时时间具体整定值。
