When the 7-ton trolley locomotive is running, sometimes sparks can be seen between the overhead wire and the pantograph. what is this? How to deal with this phenomenon?

After first discovering this phenomenon, if there is gas in the working mine, please stop quickly to avoid accidents.

Secondly, the reason why there is an electric spark between the overhead line and the pantograph is that there is a high probability that the contact between the two is not good due to the levelness and other reasons. In this case, the generation of electric sparks may not only be dangerous, but also accelerate damage to pantographs, etc.
