Title:
NON-CONTACT ELECTRIC SUPPLY PLANT
Document Type and Number:
Japanese Patent JP2006168458
Kind Code:
A
Abstract:

To provide non-contact feeding equipment capable of identifying the place in abnormal temperatures and of detecting abnormal temperatures around feeding lines by optical fiber cable.

This equipment supplies electric power with no contact from ground equipment to a power receiving coil 1 in a guided vehicle through electromagnetic induction. The optical fiber cable 4 is laid along the feeding support 2 of the feeding lines 3 and a temperature measuring device 5 is equipped at one end of the optical fiber cable 4 capable of measuring the temperatures based on an intensity ratio between the anti-stokes side and the stokes side of Raman scattering light, measuring the intensity ratio on time series and detecting the temperature distribution along the optical fiber based on light speed and receipt time.
