KPC series electric flat car is a safe trolley wire-powered electric flat car. A trench is opened on the side of the track, a safety wire is installed in the trench, and a cover plate fixed on the ground with a hinge is laid on the ground. When the electric flat car is running, the cover plate is lifted by a floor flap device installed on the flat car, and a cable connected with the safety slip wire collector is arranged in the flap device. The electric flat car is put back to the ground through the rear cover plate from the collector. Can guarantee the smooth passage of trackless vehicles. Gutter flap sliding line electric flat car is not limited by the distance traveled.
The KPJ series is a reel-powered electric flat car that uses a cable reel to exchange 380V. The cable drum is hysteresis-coupled to ensure that the cable is not stressed even when it is stressed. The exchange 380V provides electric power to the YZ lifting metallurgical motor on the flat car, and the motor drags the flat car to run. When the flat car is running, the cable drum will automatically roll up or release the cable, which is affected by the power supply length of the spool. Generally, the maximum running distance is less than 200m.
The KPT series electric flat car is a cable-powered electric flat car. One end of the cable is connected to the ground power supply, which is led to the control box through cable pulleys and traction wire ropes, and then to the YZ motor on the flat car to provide power to drive the flat car. However, the running distance should not be too long, generally not more than 50m, too long to easily wind the cable.
The KPD series is a 36V single-phase (three-phase) low-voltage rail-powered electric flat car, which is powered by rail trolley wires. The ground step-down transformer control cabinet will step down the single-phase (three-phase) AC 380V to single-phase (three-phase) 36V, fed to the flat car via the rail trolley line, and then boosted by the on-board step-up transformer to a single collector phase ( Three-phase) AC 380V. Single-phase capacitor motors are used to supply electric power to flat cars (YZ hoisting metallurgical motors for three-phase motors). Because it does not use cables, it is safe and reliable, is not afraid of hot, is not afraid of flaws, does not prevent cross-transport, easy to achieve remote control and automation, to the factory area transport arrangements to a great convenience. However, the track construction requirements are relatively high, and the current collector must ensure the insulation of the track. When the track exceeds a certain distance, a copper compensation line should be added to the track. When the running distance is long, the number of step-down transformers must also be increased.
