制御システム
Document Type and Number:
Japanese Patent JP7251886
Kind Code:
B2
Abstract:
To provide a control system which can more stably operate a DC current breaker.SOLUTION: The control system of an embodiment has: a power source device; a light emitting unit; an optical transmission line; a light receiving unit; a first power conversion section; a second power conversion section; and a control circuit. The light emitting unit emits light using power to be supplied by the power source device. A first end of the optical transmission path is connected to the light emitting unit, and a second end is connected to the light receiving unit. The light receiving unit outputs power using the light emitted by the light emitting unit and transmitted by the optical transmission line. The first power conversion section converts first voltage which is input voltage from the light receiving unit into second voltage. A second power output section converts the second voltage which is input voltage from the first power conversion section into third voltage. The control circuit operates using the second voltage to output a control signal to a DC current breaker.SELECTED DRAWING: Figure 1
