DEVICE stability control short-circuit and disable the automatic reclose the circuit breaker contact system AC

摘要

The invention relates to a system of alternating current electric power automation of railways, namely to devices feeder automation of contact network and search for a short circuit in the contact AC railways.; The purpose of utility model - simplification of the device with the realization of two functions: disable automatic reclosing (reclosure) switch with a steady short-circuit and find a contact network damage.; Summary of the utility model is that introduced by the relay once again the circuit breaker, and the prohibition of its operation and signaled a stable short circuit is carried out in the event that the induced voltage in the off contact network below the setpoint actuation voltage switch connected to the transformer control voltage induced voltage.
