GROUP STRUCTURE GROUND support of contact network

摘要

The invention relates to power supply devices disposed along the railway bed for vehicles with electric traction, namely, to the contact wire lines and support means for them. The purpose of the invention - increase the efficiency of the DC current operation Feeder Protection traction substations using a group of pole grounding contact network. The invention consists in that on a wire group earthing diode units are arranged at the ends of each cable section, the diode blocks on the border sections includes opposite one another and connected to one earthing descent, which is connected to the choke transformer-rail network. Thus the use of the proposed device allows to increase the efficiency of the current Feeder Protection traction substations, to increase the length of the group grounding cable supports of contact network, that is, increase the number of merged one rope supports that, in turn, due to the decrease in the number of diode grounding will reduce operating costs for their service.
