摘要
本装置对工业生产企业因晃电而导致生产线上的低压三相异步电动机非正常停车的问题,提供一种抗晃电及综合保护方案,能实现低压线路电网波动后再次送电时重启电动机的功能。装置基于DS1302时钟芯片,与已有的抗晃电设备相比,具有整定精度高、可重复性好、动作时间准确等特点,且无需外部为装置提供大功率后备电源。
This paper provides a scheme of anti-interference electricity to solve the abnormal stop problem of low-voltage three-phase asynchronous motor caused by interference electricity in industrial enterprises, which can implement the function of rebooting motors stopped after low-voltage power network fluctuation.The divice is based on clock chip DS 1302,compared with the existing anti-interference electricity device, it has the features of high precision, repeatability, accurate operating time and no need for external devices to provide high-power back-up power supply.
