自耦变压器启动控制及其保护的PLC改造在煤矿除尘中的应用

Autotransformer Start Control and Protection Reformed by PLC in Used of Coal Mine Dedusting

通过分析传统自耦变压器启动回路及其控制保护系统存在的问题,结合实际利用PLC进行改造,并对控制系统进行重新设计,并成功应用于某煤矿公司除尘控制系统中,达到了设计效果。

The question of the traditional autotransformer start circuit and control protection system is analyzed. The control system is redesigned by the use of the PLC in practice. It is used in the dedusting control system in some coal mine Co. successfully. It achieved the designing results.
