摘要： PROBLEM TO BE SOLVED: To provide a vacuum circuit breaker having both breaking performance and a low surge property.
SOLUTION: A substance comprising Cr, either of Cu and Ag and a carbide and forming a structure where Cr with its circumference surrounded by the carbide is dispersed in a matrix formed of a carbide and containing either of Cu and Ag as a main constituent is used for an electric contact. Sufficient breaking performance can be provided by containing Cr and either of Cu and Ag; a chopping current can be reduced by a sublimation phenomenon of the carbide in current cutoff; arc drive is facilitated; and excellent breaking performance can be exerted. In addition, the carbide is present by surrounding the circumference of Cr, whereby current-carrying performance of the matrix containing either of Cu and Ag as a main constituent can be secured and a low surge property improving action can be exerted.

摘要： PROBLEM TO BE SOLVED: To implement operating characteristics of a vacuum breaker without detaching a front cover.
SOLUTION: A hole 11 is opened at the upper part of an operator housing case 10 and a photosensor 13 is screwed (or magnetic locked) to the case 10 corresponding to the hole 11. The photosensor 13 measures movement position of the upper part 12 of an upper drive rod 9. The photosensor 13 irradiates an optical pulse toward the upper part 12 and detects stroke of the upper part 12 by an angle (or position) of reflecting light from the upper part 12. Since the photosensor 13 repeats continuously irradiation of the optical pulse in a short cycle, the change in stroke (operating speed) from the upper limit position 12a to the lower limit position 12b, or in reverse way can be measured. When the measured operating speed is deviated 20%-40% or more from an initial speed at delivery, the vacuum breaker is judged to be a lifetime.
