CENTRALIZED SUPERVISORY CONTROL SYSTEM

摘要

PURPOSE:To reduce the cable materials cost and the wiring cost by arranging each transmission terminal equipment and each distribution transformer closely and using a composite cable being the combination of an optical fiber signals wire and a high voltage power wire so as to connect the equipments. CONSTITUTION:In the titled centralized supervisory control system, the composite cable 12 comprising the optical fiber signal wire 10 and the high voltage power wire 11 is provided between plural sets of transmission terminal equipments 13 and distribution transformers 14 arranged closely, the signal of the equipment 13 is sent through the signal line 10 and the power to the transformer 14 is supplied through the power wire 11. The loop data transmission line between a central control unit 15 and each terminal equipment 13 is constituted by the said cable 12 and a loop reception/distribution path between a high voltage electric room 16 and each transformer 14 is constituted thereby. Each transformer is provided to supply a low voltage power to an installation equipment subject to supervisory control in the system.
