固态降补软启动装置在BPRT风机中的应用

Application of Step-down Solid Soft Starter in BPRT Fans

摘要：简要说明固态降补软启动装置的工作原理和技术方案，通过结合相关参数进行启动过程计算，并绘制出防真曲线。固态降补软启动装置成功应用于风机大电机启动系统中，具有启动电流小，现场调试简单的优点。

The working principle and technical proposal of step-down solid soft starter were explained briefly, then combined the relevant parameters, the starting process was calculated, and the simulation curve was drawn. When the step-down solid soft starter was used in a large motor starting system, it has many advantages such as small starting current and easy field debugging.
