弹簧机构分闸锁扣系统对高压断路器分闸时间影响研究

Gaoya dianqi
高压断路器是电力系统中重要的保护和控制设备。高压断路器可以采用弹簧机构来执行分闸动作，断路器分闸时间是指处于合闸位置的断路器，从弹簧机构分闸脱扣器带电时刻到所有各极弧触头分离时刻的时间间隔。弹簧机构分闸脱扣器动作时间在断路器分闸时间中占比50%左右，通过改变弹簧机构分闸锁扣器动作时间是调整断路器分闸时间关键因素。为有效调整断路器分闸时间，文中根据断路器分闸动作的原理，以高压断路器用弹簧机构分闸锁扣系统为研究对象，采用机械动力学仿真计算分析方法，分析分闸锁扣系统对断路器分闸时间的影响 ...

基于耦合负压的改进型多端口中压直流断路器拓扑研究

Gaoya dianqi
柔性直流配电网的可靠性建立在成熟的中压直流断路器基础之上，然而直流断路器高昂的造价限制了其在配电网中的应用。为了降低直流断路器在配电网中的投资成本，结合耦合负压换流方式，设计了一种改进型多端口混合式直流断路器。首先，对现有直流断路器的拓扑结构进行了分析；然后，提出了改进型多端口混合式直流断路器的拓扑结构，对分断故障时的动作时序进行了设计；最后，基于Pscad/Emtdc搭建了四端环网型柔性直流配电网，仿真分析了改进型多端口混合式直流断路器切除双极短路故障时的暂态特性，得到了内部电压、电流的分布情况 ...
