Many people understand that low-voltage rail flat car has a strong load capacity, unrestricted use time and long service life, but they do not know that low-voltage rail flat car can also be divided into two-phase and three-phase.
Three-phase low-voltage rail electric flat car, is the communication AC 380V switch power according to the transformer down to communication AC 36V three-phase power, each connected to four rails (lift 1 conductive rail), rail transfer cart on the wheels and conductive rail slider will rail communication AC 36V switch power into the car home appliance box, through the step-up transformer will three-phase power Communication AC 36V pressure to three-phase power communication AC 380V, and then according to the communication AC automatic control system to manipulate the communication AC metallurgical industrial motor, so that the flat car start, termination, forward, backward, etc. Two-phase low-voltage rail electric flat car, is the communication AC 380V switch power according to the transformer down to communication AC 36V two-phase, each connected to the two rails, rail transfer cart on the wheels of the rail communication AC 36V switch power into the car home appliance box, through the rectifier control module will communicate AC 36V rectifier to DC power 36V, and then According to the DC automatic control system to manipulate the DC brushless motor, so that the transfer car start, termination, forward, backward, variable speed, etc.
The two electric flat car power supply system methods are different, three compared to two-phase more than laying a rail, three-phase power supply system switch power supply balance, the project investment is very large, carrying capacity. The two-phase investment is smaller and the carrying capacity is average.
