Mining locomotive thyristor speed control device came out

An explosion-proof energy-saving thyristor speed regulating device that can be used in mine battery locomotives has been successfully developed and put on the market in Hebei Hengshui Taichang Mine Electronic Equipment Factory.

At present, most of China's mining battery locomotive speed control devices use resistor speed controllers. In the process of use, due to high energy consumption, poor safety and explosion performance, etc., it has brought many problems to the use of enterprises. It is understood that this thyristor speed control device is composed of a thyristor chopper, a controller and a flameproof box. It has the characteristics of simple circuit, energy saving and explosion proof, and its voltage adjustment range is 10% to 90% battery voltage. The surrounding medium temperature is -20 ~ 40 ° C, the ambient pressure is 80 ~ 110Kpa, with good adaptability and adjustable range.

According to the introduction of enterprise technicians, the product has two major features: First, through the use of thyristor speed control technology, the locomotive starts smoothly, the speed is even, the overload capacity is strong, compared with the resistance speed control device, saving energy 20 %, also prolongs the service life of the battery; Secondly, the explosion-proof box is used, which greatly improves the safety factor of the device, and is not only suitable for mines with prominent biogas, but also for places containing other explosive gases. The device has passed the national mining product testing and technical certification.
