摘要： An electrode for a vacuum circuit breaker provided with a connecting portion made of a material having the same resistivity as the arc running face portions across the corresponding arc guiding channel at the outer circumferential end thereof, wherein when the outer diameter of the connecting portion is D.sub.1 and the inner diameter of the connecting portion is D.sub.2, the width of the connecting portion is designed so that the ratio D.sub.2 /D.sub.1 is in a range of more than 0.9 and less than 1.0. An arc generated between the electrodes is magnetically driven over the arc running face portions via the connecting portion so that the current interrupting capacity of the electrode is increased and the size and weight of the electrode are reduced.

摘要： A low cost and highly reliable vacuum circuit interrupter and a method of manufacturing the same improve production efficiency and vacuum tight sealing property of the vacuum circuit interrupter. In the vacuum circuit interrupter, within a sealed vacuum vessel 100 a pair of separable conductors in center axial direction of the sealed vacuum vessel composed of a stationary conductor 3 and a movable conductor 5 are disposed. The sealed vacuum vessel 100 is sealed in vacuum tightness in such a manner that an upper end portion 1A of a hollow cylindrical insulation body 1 is sealed with a flexible member 6 generally called a bellows and a metal end plate 7 by joining a movable conductor side 6A of the bellows 6 to the movable conductor 5 so as to permit separation of the movable conductor 5 from the stationary conductor 3 while maintaining the vacuum sealed condition in the vacuum sealed vessel 100, and by joining one end of the metal end plate 7 with the upper end portion 1A of the hollow cylindrical insulation body 1 and the other end thereof with a metal end plate side 6B of the bellows 6. A lower end portion 1B of the hollow cylindrical insulation body 1 is sealed with the stationary conductor 3 by itself.

摘要： There is disclosed a vacuum insulation switch provided with a movable electrode, a stationary electrode and an earthing electrode, which are insulated from each other, in a vacuum container made of a conductive material which is earthed, and a switchgear using the same. Since the vacuum insulation, which is excellent in the insulation ability, is utilized, the switch is drastically miniaturized and the number of constituent parts are reduced, whereby the manufacturing cost of the switch and the switchgear can be decreased.
