摘要
电动机全压启动电压下降是电器启动和设计中必须注意的环节,关系到电网、电机寿命及电动机机械设备的安全平稳运行.文章分析了电动机启动压降的产生原因、计算及危害,提出了优化高压同步电动机的启动、电网与用户设备间加设缓冲设备及根据工况安装动态电压补偿器等应对措施,能在一定程度上保护电网和和电动机,延长电动机寿命,保障系统安全平稳运行.
Abstract
Motor full voltage starting voltage drop is a link that must be paid attention to in electrical appliance starting and design,which is related to the power grid,motor life and the safe and stable operation of motor mechanical equipment.This paper analyzes the cause,calculation and harm of the motor's starting voltage drop,and puts forward countermeasures such as optimizing the starting of the high voltage synchronous motor,adding buffer equipment between the power grid and the user equipment,and installing dynamic voltage compensator according to the working conditions,which can protect the power grid and the motor mechanical equipment to a certain extent,extend the life of the motor,and ensure the safe and stable operation of the system.
