摘要
提出了一种适用于交流50/60 Hz、额定电压AC 400 V,具有三重保护的自动转换开关电器驱动系统。其具备位置反馈冗余设计、驱动回路自动断开、软件超时判断三重保护,杜绝了电动机烧毁和开关机构损坏等故障,提高了自动转换开关电器的可靠性。
This paper presented an automatic transfer switching equipment drive control system with ternary protective mode. This system is suitable for AC 50/60 Hz, rated voltage AC 400 V power supply system. The motor drive system has redundant design of position feedback, drive circuit automatically disconnect and software timeout judgement. It can eliminate the motor burned and switch mechanism damage, so improve the reliability of the automatic transfer switch.
