礦用隔爆兼本質(zhì)安全型組合式真空電磁起動(dòng)器
Mine Explosion-proof and Intrinsically Safe Compound Vacuum Electromagnetic Actuator
適用范圍及用途
起動(dòng)器主要用于交流頻率50Hz、額定電壓1140V或660V供電線路中,對(duì)4臺(tái)礦用隔爆型三相交流感應(yīng)電動(dòng)機(jī)或兩臺(tái)礦用隔爆型三相交流雙
繞組雙速電動(dòng)機(jī)的起動(dòng)、停止、反轉(zhuǎn)及雙速切換進(jìn)行控制；同時(shí)對(duì)電動(dòng)機(jī)及其有關(guān)線路進(jìn)行保護(hù)；并可在停止時(shí)進(jìn)行換向。
Applications
The actuator is mainly used for control of starting, stopping, reversion and double-speed switch of 4 mine explosion-proof three-phase AC induction motors or two
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.
