Abstract: In order to standardize the management of the OHE gauge and ensure its safety, the meaning of OHE gauge, security risks and recent OHE intrusion accidents were analyzed according to the problems of power supply safety and railway transportation order threatened seriously by OHE intrusion accident. The shortcomings in the understanding and the problems existing in management were pointed out, and corresponding suggestions were given. The results show that the problems of OHE gauge are the majority of OHE accidents and the invasion of foreign objects is the main cause. The OHE gauge is not defined in various regulations and standards. There are some limitations in understanding the mast gauge as OHE gauge, while bringing the factors related to the gauge, such as the mast gauge, the height of contact wire, the stagger, the insulation gap and so on, into the scope of OHE gauge is beneficial to the unified management.

Key words: overhead contact line equipment(OHE), gauge, safety risk, matter, invasion
