What is the structure of a wired mine electric locomotives? Let me introduce you.

The wire-type mine electric locomotives has a simple structure, low cost, and easy maintenance. The mine electric locomotives has a large transportation capacity, high speed, high power efficiency, low transportation cost, and is widely used. Weaknesses: Rectification and wiring equipment are needed, which is not naive; the wiring has a certain impact on the size of the roadway and the tranquility of pedestrians; sparks are easily generated between the pantograph and the wiring, and it is not allowed to be used in mines with severe gas.

The investment was relatively large when it was initially established, but from a long-term perspective, the total cost of accommodating a wired mine electric locomotives is much lower than that of a battery mine electric locomotives. Therefore, if the conditions of the mine permit, the main transportation of the mine should accept wire-type mine electric locomotives.

The positive pole of the DC power supply is adjacent to the lead wire through the power supply cable. The contact of the era becomes the power supply point. The negative pole of the direct current power supply is connected to the track through the return cable. The responding contact is called the return point. In the event, the upper part of the electric locomotive running along the track obtains electrical energy by the pantograph contacting and squeezing line, and the lower part uses the wheels to contact the track to form a loop to make the traction electric idea work, so that the electric locomotive will pull the mine car. It can be seen that the running track of the wire-type electric locomotive is also the conductor of the current loop.
