Analysis of Electromagnetic Interference from Pantograph Arcing with Different Trolley Locomotive Speed in Coal Mine Tunnel

摘要：

Electromagnetic interference is very serious in the coal mine tunnel and exhibits quite different characteristics from the ground.This document gives the focus on the pantograph arcing radiation interference generated by the contact line and the trolley locomotive in the coal mine tunnel.Through the theoretical analysis and experiments in Pingdingshan Coal Mine Group,it is said that the more slowly the trolley locomotive’s speed the higher the arcing radiation interference.The maximum radiation interference of pantograph arcing is not more than -30dBmv.The results also show significantly that the wireless communication frequency used in the coal mine is better more than 1900MHz.
