基于耦合负压原理的10 kV直流负荷开关设计

open access: yesGaoya dianqi
为满足柔性直流配电系统负荷电流频繁投切对开关操作寿命的高要求,解决直接采用直流断路器方案成本高、体积大的难题,文中研究了一种基于耦合负压原理的直流负荷开关方案。首先对其拓扑和工作原理进行了介绍,然后设计了基于双动结构和电磁斥力机构的主支路快速机械开关、基于耦合负压装置的换流单元和采用反串联拓扑的电力电子开关阀单元,最后,根据苏州某换流站工程需求,研制出10 kV耦合负压型直流负荷开关样机并进行试验验证。结果表明:所研制的10 kV直流负荷开关可在3 ms内开断额定电流和最大开断电流,且能连续动作 ...
