Development of Mine Storage Battery Wired Compound Electric Locomotive

It is the most economical way to transport the electric locomotive in the mine tunnel transportation, but in many small section roadways, it can not be used near the loading station and the unloading station and where the safety regulations stipulate that the overhead line must not be suspended.

Therefore, in many mines, it has to be transported in sections, that is, from the working face to the coal storage bin, it is transported by battery electric locomotive, and then transported by overhead underground mining locomotive to the underground yard. Although this transportation process is more completely transported by battery electric locomotive It is more economical, but it needs to be equipped with a large number of electric locomotives and drivers need to set up double rails and lay coal bunkers with overhead lines, which results in extra time wasted due to shunting and loading at the coal bunkers.

A battery-powered multiple-supply electric locomotive is a device that can be powered by two power sources. When the underground mining locomotive is running in the lane with the line, it can be directly powered by the line. When it is running in the lane without the line, it is powered by the battery power supply device. It can work directly from horizontal alleys to open tunnels or work areas with biogas without wires, or directly from the production site to flat holes with high biogas, without replacing the locomotive. Therefore, production processes and transportation links can be simplified, and transportation efficiency can be improved. It also has the characteristics of wire-type electric locomotive with large traction, fast speed, good climbing performance, safe and flexible use. At present, the dual-power electric locomotive developed by Yutong | Electricity has filled the gap in China.

When the wiring network fails, the battery-wired multiple-type underground mining locomotive can use the on-board battery power supply device to continue operation. If the freight rate per ton-km of the wire-type electric locomotive is 100%, the double-energy electric locomotive is 110-120%. The battery electric locomotive is 150-180% .Because this locomotive directly uses the DC power from the line, it not only improves the traction performance of the locomotive, but also improves the power efficiency.Each locomotive can save 10,000W.h per year.
