By means of cutting, no traction power supply is generated within the whole 30km, and all vehicles along the railway line stop running due to the requirement of railway signal blocking, so that normal running of the railway line is seriously influenced.
(2) A longer recovery time is required. After the shearing, the original contact line, the carrier cable and the connection points with the cantilever, the positioner and the like are required to be dismantled from the shearing anchor section for power supply restoration, if the strut at the shearing position is damaged, the strut is required to be taken out, and the contact net is erected again. The fastest mode is to adopt the overhead line operation car, because of the vehicle parking along the line, need will influence the vehicle traction of entering such as contact net overhead line operation car through the rescue locomotive earlier and get into and dodge the line, adopt pole setting operation car, overhead line car etc. to resume the contact net this moment, still need detect high the leading after resuming, can lead to the car in the rear of meeting the requirements, and this process is consuming time for a long time, leads to the loading inefficiency.
