Introduction of Electrical Parts:

Mining trucks are typically equipped with electrically driven engines. Under high demand conditions, such as traveling on an uphill slope, power can be supplied through a trolley line. The mining transport truck draws power from the sliding wire through the pantograph. However, under certain traveling conditions, such as inside the mining pit, around the crusher, and on the horizontal plane, the mining transport truck operates independently of the sliding line. The power is then supplied by a generator powered by a diesel engine. Diesel engines require delivery and storage of fuel supplies and regular maintenance. In addition, the exhaust gases from diesel engines contribute to air pollution.

Traction power supply system refers to the power supply mode of electric energy required for the transportation of traction vehicles. The traction power supply system refers to the whole power supply system that the railway introduces 220 (110) KV power supply from the local area, depressurizes it to 27.5 KV through the traction substation, and sends it to the electric locomotive.

Advantages and disadvantages of traction power supply

Advantages of traction power supply

The advantages of electric traction in electrified railway transportation are mainly reflected in the following aspects:
  1. Electric traction can save energy and comprehensively utilize energy
  2. Electric traction can improve the traction weight of the train and the running speed of the train
  3. High braking power of electric traction and high safety during operation
  4. Low cost of electrified railway transportation
  5. Electric traction is easy to realize automation. The use of advanced science and technology is conducive to improving working conditions and environmental protection

Disadvantages of traction power supply

The disadvantages of electric traction in electrified railway transportation are mainly reflected in the following aspects:
  1. The capital construction investment is large.
  2. There are some unfavorable factors for the power system.
    Because the traction power supply is a single-phase load, it will produce large negative sequence current and negative sequence voltage in the power system, and the power factor of electric locomotive is low, and the higher harmonic content will cause adverse effects on the power system.
  3. It will cause certain electromagnetic interference to the communication lines near the railway.
  4. The catenary needs to be powered off for maintenance, and a certain skylight time is required in the train diagram, during which the train will stop running.
