KPD flat car
KPD low-voltage electric flat cars have three-phase and unidirectional power supply methods. Unidirectional flat cars are suitable for small tonnage vehicles below 50t. His advantage is that it saves a conductive rail and greatly saves investment costs.
The working principles are:
The working principle of the KPD three-phase low-voltage electric flat car is that the three-phase 380v power is passed to the track through a fixed step-down cabinet on the ground, and then sent to the step-up transformer on the car through the conductive device on the flat car. 380v drives the motor through the control system.
The working principle of the KPD one-way low-voltage electric flat car is to pass two-phase 380v power to the rail through a fixed step-down control cabinet to the rail, and then send it to the rectifier on the car through the conductive device on the flat car. Drive DC motor for DC 45v via control system.
Because the cable is not used, it is not only safe, but also not afraid of scalding and smashing. It has a long service life and does not hinder cross-transport. It is easy to realize remote control and automation. Properly increasing the number of pressure-reducing control cabinets can run for long distances without restrictions on distances. The operation is turning, but the capital investment of the track insulation is large, and the professional laying is continued.
Steel coil electric flat car is a kind of conveying equipment suitable for transporting a series of coiled profiles such as steel coil, aluminum coil, iron coil. ,
This type of electric flat car is also called rail flat car. This electric flat car is a special kind of flat car. A U-shaped device is installed above the flat car platform to prevent some coils such as steel coils and aluminum coils. The rolling of the profile guarantees 100% safety during transportation and gives users 100% peace of mind.
The drive of steel coil electric flat car and other electric flat car power supply methods are allowed, such as battery power, low voltage rail power, streamer and other power supply methods. At the same time, its motor drive uses an inverter to prevent instantaneous increase in speed due to excessive current during startup. Rolling of the roll profile. Also guarantees the service life of the motor
The steel coil electric flat car uses an AC motor to drive the operation of the flatbed. The 380V AC power supply provides electric power to the motor by sliding a safe slider to realize the operation of the steel coil electric flat car. This type of steel coil electric flat car is flexible in taking electricity and sliding, safe and reliable, and has a low failure rate. Generally there is no tonnage limit, the countertop can be made lower, but the running distance generally does not exceed 50 meters.
Abnormal noise occurs when the control circuit generally emits "hum" noise. Most of the contactors are faulty (such as poor contact of the contactors, voltage levels are not consistent, the magnetic core is stuck, etc.). The faulty contactor should be repaired. After replacement, the noise will be eliminated by itself after disposal. Electric flat car external force type cable reel (chain drive type) is composed of cable reel, permanent magnet coupler, (cable hysteresis), slip ring collector box, clutch drive sprocket, chain and mounting bracket. The walking wheel shaft in the transmission system of the mobile device is selected as the power output, and the power is transmitted to the permanent magnet coupler via the chain. After the permanent magnet coupler continuously slips, the drive reel synchronously winds the cable.
The location can be selected according to the specific use environment of each user. It can be installed in the middle of the track, it can also be installed on one side of the track, in the trench, or on the wall, or under the flatbed, or above the steel coil electric flatbed, or it can be flush with the flatbed platform. The principle of taking electricity is convenient, safe and reliable. For example, it will be installed in a trench, and a cover plate is installed on the trench (the cover plate is not a through plate, but a section by section). When the car is walking, the board is opened and closed automatically, which is both safe and beautiful.
