35 Tons low-voltage rail power supply industrial trailer indoor
As the name suggests, the low-voltage trailer is a kind of equipment that uses the low-voltage track power supply mode to provide power to the electric flat car motor and drive the wheels through the electrical control system. It is now widely used.
KPD series low-voltage trailer is a 36V single-phase (three-phase) low-voltage rail powered electric flat car, which is powered by rail. The ground step-down transformer control cabinet will reduce the single-phase (three-phase) AC 380V to single-phase (three-phase) 36V, feed it to the flat car through the track, and then boost it to single-phase (three-phase) AC 380V through the on-board step-up transformer. Supply power to single-phase capacitor motor for flat car.

Since the track power supply low-voltage trailer does not use cables, it is safe and reliable, not afraid of scalding and smashing, does not hinder cross transportation, and is easy to realize remote control and automation, which greatly facilitates the transportation layout in the plant area. However, the track construction requirements are high, and the track insulation must be ensured. When the running distance exceeds a certain distance, the track shall be added with copper bar compensation wire. When the operation distance is long, the number of step-down transformers must be increased.
The low-voltage trailer with high-precision automatic fixed-point parking includes the electric flat car and the controller. The surface of the electric flat car is bolted with an induction sensor, the limiting rod is pressed on the surface of the limiting seat, and the limiting seat is bolted on the surface of the electric flat car. When the low-voltage trailer is running, it is measured by a radar rangefinder. When the induction sensor senses the signal of the induction belt, it is transmitted to the controller in the electric flat car, Make the air cylinder shrink downward and make the brake disc squeeze on the surface of the driving rod, the limiting driving rod rotates, and then the electric flat car stops. At the same time, the stepping motor drives the threaded rod to rotate, so that the limiting rod is close to the surface of the limiting seat and finally squeezed on the inner wall of the limiting groove in the limiting seat, further limiting the movement of the electric flat car, realizing automatic high-precision fixed-point parking, which is suitable for promotion.
