Electric flat car, is a kind of electric rail transportation inside vehicle. Also calledJumbo, cross vehicle. It has the advantages of simple structure, convenient use,easy maintenance, has the advantages of large bearing capacity, less pollutionand so. Widely used in machine building and metallurgical plant, as the workshopinterior coordination crane to transport heavy cross purposes. KP series of electric flat car low height, mesa strengthening, modification easy, convenient repair.
KPJ series is the drum power supply electric flat car, with a cable reel AC 380Vpower supply. Cable reel for hysteresis coupling, ensure that the cable force uniform is not easy to bad. AC 380V to YZ flat car for metallurgical use motor to provide power, motor drive car operation. Car running cable reel with automaticcable rolled up or release by reel power supply, the effect of length, usually the maximum operating distance is less than 200m.
The KPD series is 36V single phase (three phase) of low voltage rail to rail power supply electric flat car, the sliding contact line power supply. Ground step-down transformer control cabinet will phase (three phase) of AC 380V buck to single phase (three phase) 36V, the rail sliding contact line is fed to the car, and then by car step-up transformer for single phase AC 380V (three). Providing power to a flat cars for single-phase capacitor motor (three phase motor with YZ for crane and metallurgical). Because there is no cable, so it is safe and reliable, not afraid of hot, not afraid to hit, not cloggy cross transportation, easy to realize remote control and automation, to plant layout with very convenient transportation. But the track construction requirements higher, should ensure that the rail insulation,more than a certain distance running track should be added to coppercompensation line. Running distance is longer must also increase the number ofstep-down transformer.
Because the KPD flat start passing through the track starting current is very large (up to 1000A), at the end of track have large voltage drop, resulting indifficult starting of single-phase capacitor motor, so the single-phase KPD flatmaximum tonnage of 50 tons, 50 tons of truck above three phase 36V low voltage rail power supply, YZ motor for heavy metallurgy.
Product KPDZ not only inherits advantages of KPD flat car and avoids the difficulties start prototype, short running distance disadvantage. KPDZ car to carrectifying device on track (single-phase or three-phase AC into DC rectifier) 36V36V, make flat car running drag DC traction motor, DC motor and AC motorcompared with less burning loss, large starting torque, strong overload capacityof the advantages. Even if because of track insulation aging, still can work reliably in undervoltage condition.
KPX battery is a battery electric car series, with battery power supply. The battery provides power for DC traction motor, DC motor drive car operation. DC motor and AC motor compared with less burning loss, large starting torque,strong overload capacity of the advantages. Distance running is not restricted. It has greater safety performance and flexibility than KPJ, KPD two series of flat car, running distance is not restricted, no insulation requirements on the track,so convenient construction and low cost.
All flat car can be added to a wireless remote control device for industry.
