CUTOFF SWITCH CONTROL METHOD OF KOREAN-TYPE HIGHWAY-RAILWAY

摘要

A cutoff switch controlling method of a Korean-type high-speed railway is provided to prevent electric/electronic devices in a motorized car from being damaged by over-current by operating a cutoff switch to cut off the over-current applied to the motor vehicle. A cutoff switch controlling method of a Korean-type high-speed railway includes the steps of: transmitting a cutoff switch control command of a predetermined voltage to a VCU(Vehicle Control Unit) of a motorized car by an SCU(Signal Control Unit) of a motorized car as a network signal when any one signal among an over-current detecting signal, a cooling disorder signal, and a fire detecting signal of a main transformer of the motorized car is applied and a vacuum circuit breaker is turned off; and allowing a cutoff switch to perform a cutoff operation by outputting a cutoff coil control signal for a predetermined time by the VCU of the motorized car which receives the cutoff switch control command through a network.
