Power supply facility

1 . A power supply facility comprising:

at least one feeder cable disposed along a moving path of a movable body and configured to contactlessly supply electric power to the movable body; and

a heat sensitive unit disposed along the moving path together with the at least one feeder cable, and

wherein:

the at least one feeder cable comprises:

a conductor bundle bundling up a plurality of conductor lines through which an alternating-current flows; and

an insulating coating covering the conductor bundle,

the heat sensitive unit comprises:

a first heat sensitive wire contained inside the insulating coating of the at least one feeder cable and extending along an extending direction of the at least one feeder cable together with the conductor bundle; and

a second heat sensitive wire disposed at a position next to the at least one feeder cable and extending along the extending direction of the at least one feeder cable together with the at least one feeder cable, and

the power supply facility further comprises:

a first detector configured to detect abnormal heat generation from the first heat sensitive wire;

a second detector configured to detect abnormal heat generation from the second heat sensitive wire; and

a controller configured to control an alternating-current power source for supplying electric power to the at least one feeder cable, and

wherein in response to either of the first detector and the second detector detecting abnormal heat generation, the controller outputs a warning, and in response to the first detector and the second detector both detecting abnormal heat generation, the controller stops power supply from the alternating-current power source to the at least one feeder cable.

2 . The power supply facility according to claim 1 , wherein:

the first heat sensitive wire is disposed in a central part of the at least one feeder cable, the central part being surrounded by the conductor bundle, and

the second heat sensitive wire is disposed in contact with the insulating coating of the at least one feeder cable.

3 . The power supply facility according to claim 1 , further comprising:

a support member disposed along the moving path and supporting the at least one feeder cable and the second heat sensitive wire, wherein the support member comprises:

a first holder holding the at least one feeder cable; and

a second holder holding the second heat sensitive wire, and

wherein disposing the at least one feeder cable in the first holder with the second heat sensitive wire in the second holder prevents the second heat sensitive wire from falling from the second holder.

4 . The power supply facility according to claim 3 , wherein:

the first holder has a recessed groove shape within which the at least one feeder cable is fitted, and

the second holder has a recessed groove shape in which the second heat sensitive wire is contained, such that the second holder is opened on an inner surface of the first holder.

5 . The power supply facility according to claim 1 , wherein:

in response to either of the first detector and the second detector detecting abnormal heat generation, the controller does not stop the supply of power from the power supply to the at least on feeder cable.

6 . The power supply facility according to claim 1 , wherein:

the movable body comprises a power reception device configured to receive driving electric power from the at least one feeder cable,

a pair of the feeder cables each disposed on each side of the power reception device in a path width direction along a horizontal surface and perpendicular to a direction along the moving path, and

a pair of the second heat sensitive wires are disposed outwardly in the path width direction from the pair of feeder cables.

7 . A power supply facility comprising:

at least one feeder cable disposed along a moving path of a movable body and configured to contactlessly supply electric power to the movable body; and

a heat sensitive unit disposed along the moving path together with the at least one feeder cable, and

wherein:

the at least one feeder cable comprises:

a conductor bundle bundling up a plurality of conductor lines through which an alternating-current flows; and

an insulating coating covering the conductor bundle,

the heat sensitive unit comprises:

a first heat sensitive wire contained inside the insulating coating of the at least one feeder cable and extending along an extending direction of the at least one feeder cable together with the conductor bundle; and

a second heat sensitive wire disposed at a position next to the at least one feeder cable and extending along the extending direction of the at least one feeder cable together with the at least one feeder cable,

the at least one feeder cable comprises a plurality of feeder cables electrically connected to each other via a terminal block,

at least one of the first heat sensitive wire and the second heat sensitive wire is a target heat sensitive wire including a terminal block corresponding part disposed in contact with the terminal block, and the terminal block corresponding part is detachably connected, via a connector, to a part of the target heat sensitive wire which part is along the insulating coating of the at least one feeder cable.
