Abstract

PURPOSE: To easily detect the detrioration of a vacuum valve type circuit breaker through a simple construction, by optically detecting the degree of contamination of the inside surface of the insulating glass cylinder of a vacuum vessel due to the deposition of metal particles.
CONSTITUTION: Flux of light emitted from a light source 11 permeates the insulating glass cylinder 5 of a vacuum valve circuit breaker and is reflected by a main shield 8. The reflected flux of light permeates the insulating cylinder 5 again and is received by a photosensitive element 12. The detection output of the element 12 is compared with a reference value to determine the degree of contamination of the inside surface of the insulating cylinder 5 due to the deposition of metal particles corresponding to the deterioration of the vacuum valve circuit breaker. The deterioration can thus be easily detected through a simple construction.
