Description

Use The device is used in coal mines containing explosive gas(methane) and coal dust. In the three-phase neutral power supply system with rated voltage ***0V, **0V or **0V, AC *0Hz, rated current **0A, it can control the start or stop of the three-phase asynchronous motor closely or remotely, and can change the phase sequence after the load motor stops. Features The main circuit adopts vacuum contactor, having long life and reliable performance. Using self-developed WTB*1 type microcomputer monitoring device, comprehensive functions, stable and reliable. Can be used by a single one or program-controlled combination. Having a RS**5 interface realizing the four distance functions: "remote regulating", "remote measurement", "remote signaling", "remote control", becoming an important part of digitized mines. Using simple control lines and the fast-open door structure, easier to maintain. Main Technical Parameters Model: QBZ****0N Rated voltage: ***0/**0/**0 Rated Current:**0A The Maximum Power of the control motor: **0V***0kw **0V**8kw
