What Is A Line-Type Electric Narrow Gauge Locomotive?

What is a line-type electric locomotive? What about wire-type narrow gauge locomotive? Today electric locomotive manufacturers-come to explain to you what is a wire-type narrow gauge locomotive.

The wire-mounted electric locomotive mobilizes the wheels to rotate through the transmission installation, thereby pulling the train to travel. The current flowing from the electric idea flows back to the substation through the track. The wire-type narrow gauge locomotive is that the current transmitted to the wire by the traction converter enters the circuit of the electric locomotive through the receiver and the narrow gauge locomotive, and then returns to the converter through the track. There are two kinds of DC voltages for underground power grids in my country: 250V and 550V, and 550V and 750V in the open air.

Wired narrow gauge locomotive has simple structure, low cost, convenient maintenance, large locomotive transportation ability, high speed, high power efficiency, low transportation cost, and the most widely used. Weaknesses: rectification and wiring equipment is required, not naive; wiring has a certain impact on the size of roadways and pedestrian quietness; sparks are easily generated between pantographs and wiring and are not allowed to be used in serious gas mines; initial establishment The investment is relatively large, but from a long-term perspective, the total cost of accepting a wired electric locomotive is much lower than that of a battery electric locomotive. Therefore, if the conditions of the mine allow, the main transportation of the mine should adopt the wire-type electric locomotive.

The positive pole of the DC power supply is connected to the squeezed wire conductor through the power supply cable. The contact of the era becomes the power supply point, and the negative pole is connected to the track through the return cable. The response point 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 the squeeze line, and the lower part uses the wheels to contact the track to form a circuit to make the electric traction thought, so that the electric locomotive hauls the mine car. It can be seen that the running track of the wire-type electric locomotive is at the same time the conductor of the current loop.

In order to eliminate the voltage drop of the traction grid, it is common to use wire or copper to connect at the joints of the rails to eliminate the resistance at the joints. The working history of the wire-type locomotive After the high-voltage alternating current is reduced and rectified by the traction converter, the positive electrode is connected to the squeeze line, and the negative electrode is connected to the rail. The pantograph on the locomotive is in contact with the squeeze line to introduce current into the car, and then enter the traction electric idea through the automatic air switch, controller, and resistance box to drive the electric idea to run.
