摘要

本文介绍了在用电公司厂区内发电设备的输出母线与电力公用侧母线之间互连的晶闸管开关。可控硅开关起着保护发电设备不受电压跌落和中断影响的作用。为了使整个装置紧凑，晶闸管开关只安装在两相中，消除了三相中的一相开关。采用无纹波的直流转换电压信号快速检测电压降。通过发电机组合试验验证了系统的性能。

High speed switchgear protecting power generating facilities against voltage dip and interruption

This paper describes thyristor switches interconnected between the output bus of power generating facilities and the bus on the power utility side located in the premises of the power-consuming company. The thyristor switches play the role of protecting power generating facilities against voltage dip and interruption. In order to make the overall unit compact, thyristor switches are installed in only two phases by eliminating a switch of one phase out of three. A DC-converted voltage signal without ripple is employed to detect voltage drop quickly. The performance of the system is confirmed checked by generator combination tests.<>
