How to design the technical scheme of 25 ton low voltage rail flat car?
25 ton low voltage rail flat car is very popular in the market. Although the track laying is slightly complicated, it is more safe and reliable in operation and operation without the influence of power supply cables and batteries. So, how should the low-voltage rail flat car technical plan be designed?
Due to the complicated conditions of track laying, in the technical plan, the design of 25 ton low voltage rail flat car should be divided into two aspects: the basic design of the track laying and the structural design of the flat car, the two should be perfectly integrated.
In terms of laying the track foundation, the requirements on the track are relatively high, and the insulation of the track must be guaranteed, which increases the installation cost of the track. When the voltage drop is large, the use of copper bars to connect the compensation line at a certain distance will also increase. The number of transformers.
According to the workshop environment and production requirements, the speed of the flat car will be controlled, and the running speed of the low-voltage rail flat car is conventionally controlled at 0 to 30 meters per minute. According to the actual needs, the speed adjustment of the low-pressure rail car is controlled by the speed control knob.
In the control system of low-voltage rail flat cars, special attention is needed, this is the brain center of the entire flat car operation.
1. The inverter of the low-voltage rail car can start and stop the protection of the motor without impact, and start and stop smoothly.
2. The on-board control box and handheld remote control of the low-voltage rail flat car can operate the electric flat car at the same time, including forward, backward, emergency stop and stop.
In terms of product advantages, the low-voltage rail flat car uses rail power supply, so it is safe and reliable, and it is not afraid of scalds, smashing, or interfering with cross transportation. It can run on bends, ring tracks, or even forks because there is no power supply cable. To avoid cable winding accidents, low-voltage rail flat cars are easier to control.
In terms of structural accessories for 25 ton low voltage rail flat car, the electrical control equipment consists of on board control cabinets, power supply devices, etc. The handles are equipped with emergency stop buttons, the car is equipped with sound and light alarms, and the electrical cabinet is equipped with a general power switch. Not only that, the complete set of low-voltage rail flat car electrical equipment also has power distribution protection, short circuit protection, over current protection, voltage loss protection, zero protection, emergency power off protection, safety signs, etc., ensuring the transmission performance and control of flat cars. The performance and protection performance enable the flat car to stop safely and reliably in an emergency.
