Mining flameproof and intrinsically safe low voltage AC soft starter


Main application

  The control unit  WTR-200 of QJR-800/1140(660)-2 Mining explosion-proof and intrinsically safe low voltage AC soft starter (hereinafter referred to as soft starter) is a product independently developed by our company.It adopts advanced microprocessor and power electronic control technology, realizes the soft start of AC motor, eliminates mechanical and electrical shock to the maximum extent, prolongs the service life of equipment, and is an ideal replacement product of hydraulic coupler and other motor starting equipment.It has the characteristics of advanced technology, safe and reliable work, easy maintenance, big starting torque and long service life, and its technical performance has reached the international advanced level.
  The soft starter is suitable for coal mines containing explosive gas (methane) and coal dust.In an AC 50Hz, voltage 1140V or 660V, neutral ungrounded power supply system, various forms of soft start (such as current clipping, voltage ramp and power torque ramp) are performed on three-phase squirrel-cage motors with currents up to 800A. The controller also has the perfect protection function and the fault display function, greatly reduces the time of troubleshooting.
