Title: Optical current transformer
Inventor: WAKANABE KOUICHI
IPC: G02B6/00
Filed: 1995-12-05
Abstract: PROBLEM TO BE SOLVED: To avoid the occurrence of stress in an optical fiber caused by a temperature change and large vibration even in the environment, wherein the temperature change and the vibration are large, and to make it possible to perform highly accurate current measurement by containing the optical fiber in the opening part of an insulating spacer. SOLUTION: An optical fiber 4 is arranged between an insulating material 3a of an insulating spacer 3 and a metal ring 3b covering the material 3a and fixed with a metal plate 8. Therefore, the optical fiber 4 is not exposed to high-pressure SF6 gas filled in a tank 1 of a gas insulating switch device (GIS). Thus, the effect of the drastic temperature change generated at the time of the current conduction of a conductor is hard to receive. Therefore, the stress generated in the optical fiber 4 can be suppressed. Furthermore, since the vibration of the optical fiber 4 itself by external shocks and vibrations is suppressed, the highly accurate current measurement can be performed.
