Abstract
A power supply system (1001) according to the present disclosure supplies power to a relay apparatus (2) on a branching submarine cable branched from a trunk submarine cable by a branching apparatus (1). The power supply system (1001) according to the present disclosure supplies power to the relay apparatus (2) by a branching power supply path (BE) connected to a trunk power supply path (TE) provided in a trunk submarine cable. When power is supplied to the relay apparatus (2), the branching power supply path (BE) causes a current flowing from one side of the trunk submarine cable to flow to the relay apparatus (2), and then causes the current to turns back so that the current flows to the other side of the trunk submarine cable.
Claims7
A power supply system comprising:
- two systems of trunk submarine cables,
- two branching apparatuses, and
- at least one relay apparatus, wherein:
- the power supply system is configured to supply power to the at least one relay apparatus on a branching submarine cable, the branching submarine cable is branched from one trunk submarine cable of the two systems of trunk submarine cables by one branching apparatus of the two branching apparatuses,
- power is supplied to the at least one relay apparatus by a branching power supply path connected only to a trunk power supply path provided in the one trunk submarine cable, and
- when power is supplied to the at least one relay apparatus, the branching power supply path enables a current flowing from one side of the trunk power supply path to flow to the at least one relay apparatus, and then enables the current to turn back so that the current flows to the other side of the trunk power supply path.
A power supply method comprising:
- supplying power to at least one relay apparatus on a branching submarine cable, the branching submarine cable is branched from one trunk submarine cable of two systems of trunk submarine cables by one branching apparatus of two branching apparatuses, the two systems of trunk submarine cables and the two branching apparatuses are included in a power supply system, wherein:
- power is supplied to the at least one relay apparatus by a branching power supply path connected to only to a trunk power supply path provided in the one trunk submarine cable, and
- when power is supplied to the at least one relay apparatus, the branching power supply path enables a current flowing from one side of the trunk power supply path to flow to the at least one relay apparatus, and then enables the current to turn back so that the current flows to the other side of the trunk power supply path.
