QJZ1-1200/1140(660)-6

矿用隔爆兼本质安全型组合式真空电磁起动器

Mine Explosion-proof and Intrinsically Safe Compound Vacuum Electromagnetic Actuator

适用范围及用途
起动器主要用于交流频率50Hz、额定电压1140V或660V供电线路中,对6台矿用隔爆型三相交流感应电动机或三台矿用隔爆型三相交流双绕组双速电动机的起动、停止、反转及双速切换进行控制；同时对电动机及其有关线路进行保护；并可在停止时进行换向。

Applications
The actuator is mainly used for control of starting, stopping, reversion and double-speed switch of 6 mine explosion-proof three-phase AC induction motors or three mine explosion-proof three-phase AC double-winding double-speed motors in the power supply circuit, with the AC frequency of 50Hz, rated voltage of 1140V or 660V. Besides, it’s suitable for protection of the electromotor and relevant circuit and reversion when it stops working.


主要特征
