高压软起动在压缩机负载上的应用

高压大功率电机在起动时对负载和电网都有比较大的影响。晶闸管串联式高压软起动器以其优越的起动性能和其他一些优点两被广泛使用。本文通过高压软起动器在现场大功率压缩机负载上的应用，分析其工作原理，介绍了起动功能，对晶闸管串联方式的高压软起动做了比较全面的介绍。

The Application of High-voltage Soft Starter in Compressor Load

When high voltage high power motor is starting,it has great influence to load and power net.Thyristor series type high voltage soft starter is used widely because of its ascendant capability.This paper analysed its work principle,introduced start-up function, and introduced thyristor series type high voltage soft starter by the application of high- voltage soft starter in the field compressor load.
