Abstract

An object of the present invention is to provide a non-contact electricity feeding facility that feeds electricity to a rail guided vehicle in a non-contact manner, the facility enabling a temperature abnormality in a feeding cable to be reliably detected using a simple configuration. The present invention provides a non contact electricity feeding facility 7 that feeds electricity to a rail guided vehicle 5 in a non-contact manner, the facility including a thermostat 43 mounted at an end of the feeding cable 9 at a connection between a feeding cable 9 and a bus bar 12 for junction or termination which is required for feeding electricity, the thermostat 43 operating at least a predetermined temperature, and a temperature abnormality detecting circuit 44 that detects that the thermostat 43 has operated.

Claims

1. A non-contact electricity feeding facility that feeds electricity to a rail guided vehicle in a non-contact manner via a feeding cable laid along a traveling track, the facility being characterized by comprising a thermostat mounted at an end of the feeding cable at a connection between the feeding cable and a bus bar for junction or termination which is required for feeding electricity, the thermostat operating at least a predetermined temperature, and a temperature abnormality detecting circuit that detects that the thermostat has operated.

2. A non-contact electricity feeding facility according to claim 1, characterized in that the thermostat operating at least the predetermined temperature is also mounted on a bus bar side to which the feeding cable is connected.

3. A non-contact electricity feeding facility according to claim 1, characterized in that the thermostat used is or a type that performs power interrupting operation at least the predetermined temperature and a plurality of the thermostats are mounted by being connected together in series, and in that the facility has a temperature abnormality detecting circuit that detects that at least one of the thermostats has performed the power interrupting operation.

4. A non-contact electricity feeding facility according to claim 1, characterized in that the temperature abnormality detecting circuit comprises a circuit that holds information indicating that any of the thermostats has operated.
