矿用防爆变频开关的设计应用

Frequency conversion switch's application designed for mine prevent from exploding

矿用防爆变频开关将变频控制技术与传统的磁力起动器捆绑,既可以变频控制也可以旁路工频工作,具有良好的调速特性和节能效果,在煤矿井下有着广泛的应用前景。

Frequency conversion switch for mine prevent from exploding combined with the tradition magnetic force starter with frequency conversion control technique,can be work under the frequency conversion,also can be work under the 50HZ,be of good characteristic of adjusting speed and the effect of reducing the consumption of energy,having good prospect applying broadly in coal mine in the pit.
