DEVICE INTERFACE insulates contact network and NEUTRAL LINKS FOR RAILWAYS high-speed lines, electrified on alternating current

摘要

Apparatus insulating conjugation catenary and neutral inserts for high-speed lines railways electrified with alternating current comprises a catenary left and right of the substation feeding from different phases of traction transformer, phases A and B which are attached to the trolley line, a phase C is attached to rails to prevent short-circuiting between the phases A and B is equipped with two insulating gap, between which turns the catenary portion which is not attached to any of the phases and of tlichayuscheesya fact that in the proposed device, as an executive authority protection from the occurrence of destructive arc applied stepwise variable resistances, consisting of two parts, one of which - "contact" is an extension of the trolley wire and replaces it with a suitable and extending portion from isolated gaps, and the other - a set of damping resistance with trains that are connected to the contact part, referred to the resistance placed on insulated cable supporting pole Trailing second part representing the number dialed in the series circuit and isolated conductive parts, which are connected to loops resistors performing the function of gradually reducing the current to a value not capable of causing the destruction of the live parts.
