摘要
The present invention relates to a control method of a cutoff switch of a Korean high-speed railway, and in particular, any one of an overcurrent detection signal, a cooling failure signal, and a fire occurrence detection signal of a peripheral pressure of a vehicle is applied, and when the vacuum circuit breaker is turned off, the SCU of the power vehicle is Transmitting a 25KV disconnect switch disconnect control command to the VCU of the power vehicle as a network signal; The VCU of the power vehicle receiving the 25KV disconnect switch cutoff control command through the network configures the second process to output the cutoff coil control signal of the 25KV cutoff switch for a predetermined time so that the cutoff switch operates. In case of over-current of electric wire, breakdown of surrounding pressure or fire, it is possible to control the shutoff switch of power car to cut-off position quickly, and it can prevent the electric and electric equipment inside Korean high-speed railway from being damaged by over-current. The present invention relates to a control method of a cutoff switch of a Korean high speed railway.;Korean high speed rail, power car, peripheral pressure, power car, SCU, VCU,
