高压电动机软启动装置的运用分析

Application Analysis of Soft Start Device of High Voltage Motor

在电力工程中,高压电动机占据着重要的地位,它结构简单,运行可靠,不需要投入过多维护资源,以上种种优点使得高压电动机在电力工程中得到了广泛的应用.但是,启动问题一直是高压电动机面临的重大阻碍,如果高压电动机发生启动问题,不仅电动机本身会遭受机械损伤,降低使用周期和寿命,对局部电网电压也会造成极大影响.文章以6kV高压电动机为例,介绍直接启动会对电动机造成的弊端,同时阐述软启动的方法,希望为电动机软启动方面的研究提供技术和理论上的支持.

In power engineering,high-voltage motor occupies an important position.Its structure is simple,operation is reliable,and it does not need to invest too much maintenance resources.All these advantages make high-voltage motor widely used in power engineering.However,the start-up problem has always been a major obstacle for high-voltage motors.If high-voltage motors start,not only the motor itself will suffer mechanical damage,reduce the service life and life,but also the local grid voltage will be greatly affected.This paper will take 6 kV high-voltage motor as an example,introduce the disadvantages of direct starting to motor,and describe the method of soft starting,hoping to provide technical and theoretical support for the research of motor soft starting.
