我国自制的煤矿防爆绞车虽已鉴定并已小批量生产,但该绞车仍用绕线电机转子串接电阻的控制方式,并沿用地面绞车的传统控制系统。而且电阻的防爆和散热又不易解决,使成套电控设备价格昂贵。因此,研制新的防爆拖动控制系统是很必要的,而目前改善现有的控制系统,降低其成本尤有现实意义。 Although China’s self-made coal mine explosion-proof winch has been identified and has been small batch production, but the winch is still winding motor rotor winding resistor control, and follow the winch of the traditional ground control system. And the resistance of explosion-proof and heat dissipation is not easy to solve, so complete sets of electronic control equipment is expensive. Therefore, the development of new explosion-proof drag control system is necessary, but the current improvement of the existing control system to reduce its cost of particular relevance.
