热变电阻软启动装置在风机启动中的应用

Application of Thermal Variable Resistance Soft Starting Unit during Fan Starting

针对大中型风机存在的启动问题,在对比分析几种启动方式的基础上,介绍了一种适用于不频繁启动的启动装置———热变电阻软启动装置及其工作原理和实践情况。

Against the problem existed during large fan starting, based on comparative analysing a few of starting modes, thermal variable resistance soft starting unit and its working principle and practice are introduced.
