晶闸管交流电子开关的主电路由两个反并联晶闸管支路构成,每个支路分别由两只晶闸管并联组成, 共使用四只晶闸管( 联接方式如图2 所示) 。按照电气化工程设计的要求, 晶闸管交流电子开关安装于牵引变压器附近的移动房屋内, 结合应用工况该装置对控制系统有如下要求:
(1) 应具有高度的可靠性, 以适应电铁供电网长期处于运行状态的客观要求;
(2) 应具有完善的事故报警系统, 发生故障后应该指示出故障类型, 无故障运行时应指示出电力电容器的投切状态;
(3) 应具有完善的逻辑控制和自动保护功能;
(4) 应确保晶闸管在电压过零点触发;
(5) 应具有良好的电磁兼容性能, 能够适应牵引变电站现场复杂的电磁环境。
