Reference numeral 1 denotes an automatic control unit (hereinafter referred to as an SCU) installed in the head drive, and the first input switch 2 and the second input for setting the input of the vacuum circuit breaker to the SCU 1. A switch 3 is connected, and a vacuum circuit breaker (VCB) 5 having a power interruption function in an emergency is connected.

Reference numeral 4 denotes an R-SCU (Rear-Supervisory Control Unit, hereinafter R-SCU) of the opposite power vehicle, that is, the rear power vehicle.

The vacuum circuit breaker input control method of the Korean-type high-speed railway of the present invention implemented by the hardware configuration configured as described above is as follows.

First, the first input condition of the VCB 5 is satisfied, that is, a pantograph rising condition, an emergency braking control signal non-approval condition of ATC (Automatic Train Control, ATC), ATS (Automatic Train Supervision, hereinafter ATS) VCB (5) is introduced into the SCU (1) of the head drive when the first input switch (2) is turned on while the emergency braking control signal non-approval condition and the interrupt control signal non-approval condition of the ATC and VCB are satisfied. When the switch-on signal is supplied, the SCU 1 determines whether the pantograph is raised in the leading power difference or the pantograph in the opposite power car.

As a result of the determination, if the pantograph is raised in the head power difference, the SCU 1 outputs a control signal for the closing operation of the VCB 5 that satisfies the first closing condition so that the first closing condition of the VCB 5 is established. Be sure to

If the pantograph is raised in the tail power difference as a result of the determination, the SCU 1 uses the network signal to input the VCB 5 that satisfies the first input condition to the R-SCU 4 of the tail power difference. After transmitting the command signal and receiving the command signal for the closing operation of the VCB 5, the R-SCU 4 outputs a control signal for the closing operation of the VCB 5 that satisfies the first injection condition to generate the VCB ( The first input condition of 5) is established.

On the other hand, when the second input switch 3 is turned on in the state where the first input condition of the VCB 5 is established, the SCU 1 is first in a state in which the second input condition of the VCB 5 is satisfied. Determine whether the pantograph of the power car is up or the pantograph of the rear power car on the opposite side is up.

The second input condition of the VCB 5 is a normal position condition of a safety switch, a motor block (hereinafter referred to as MB) and a power auxiliary block (hereinafter referred to as AUXB) of the main power difference are normal. Condition, MB and AUXB of tail power difference are normal condition, 25KV wire voltage detection condition, 25KV overcurrent detection condition, fire detection condition, ground fault detection condition, 670VDC disconnection condition.

If the pantograph of the opposite power vehicle other than the leading power vehicle is raised as a result of the determination, the SCU 1 of the VCB 5 that satisfies the second input condition to the R-SCU 4 of the rear power vehicle through the network signal is satisfied. The R-SCU 4, which transmits a command signal for the closing operation and receives the command signal for the closing operation of the VCB 5, outputs a control signal for the closing operation of the VCB 5. The second input condition is established.

On the other hand, when the ON signal of the second input switch 3 is applied in the master controller off state condition or when the re-insertion signal of the VCB 5 is applied by the ATC, the pantograph is applied in a vehicle to which the input switch signal of the VCB 5 is applied. When is raised, the input control signal of the VCB 5 is directly output for 3 seconds.

If the pantograph is raised on the opposite side of the vehicle to which the input switch signal is applied, a command signal for input operation of the VCB 5 is supplied to the R-SCU 4 via the network signal, and the VCB is supplied. Upon receiving the command signal for the closing operation of (5), the R-SCU 4 outputs a control signal for the closing operation of the VCB 5 for 3 seconds under the pantograph selection condition.
