What are the advantages of the mining electric locomotive with compound energy?

Mining electric locomotives are generally divided into wire electric locomotives and battery electric locomotives. Then battery electric locomotives are divided into ordinary lead-acid battery electric locomotives, maintenance-free battery electric locomotives and lithium battery electric locomotives according to the different batteries used. But in general, it is still divided into two types according to the energy supply method: wire type and battery. Both types of electric locomotives have their own advantages and disadvantages.

There is no conflict between the two energy supply methods, so some people try to load them on the same electric locomotive, that is, the compound energy electric locomotive. But it has an obvious problem. It is enough to use one energy supply method for an electric locomotive, and the two sets of functional systems appear to be redundant. Does it have any eye-catching advantages?

The advantage of the hybrid energy electric locomotive is that it is both a trolley electric locomotive and a battery electric locomotive. As an explosion-proof battery electric locomotive, it can directly enter the working environment with the risk of gas and coal dust explosion. At the same time, if the new route has not yet erected an overhead line, it can also be put into work immediately as long as there is a track. As a wire-type electric locomotive, it has large traction and strong climbing ability, and does not need to set up a special charging room. And because of the combination of the two energy supply modes, it can charge the storage battery when it is used as a trolley electric locomotive.

To sum up, the advantage of the hybrid energy electric locomotive lies in its adaptability to the working environment.
