    摘要： It is possible to reduce a stress due to an impact and a vibration caused by an operation of opening or closing the vacuum circuit breaker without increasing a weight and a size of a vacuum circuit breaker, to thereby reduce a bend of a case of an operating mechanism part and to thereby improve a reliability to the operation of opening or closing the vacuum circuit breaker. A vacuum circuit breaker of the present invention is a vacuum circuit breaker that includes a vacuum valve, in which at least a fixed side electrode and a movable side electrode are stored and whose periphery is covered with a mold part, and an operating mechanism part which drives the movable side electrode, and is characterized in that the vacuum valve and the operating mechanism part are arranged on a straight line and characterized by including a fixing member which extends over and fixes the mold part of the vacuum valve and the operating mechanism part.

    摘要： This invention refers to a kind of embedded-pole high voltage electrical apparatus combination switchgear with a function of a five prevention interlock, which is custom-designed for technical issues of low degree of integration and modularization of like products. It consists of an EP bracket, an EP spring operating mechanism and disconnecting earthing switchgear. Three EPs in one row are set in the bracket. The spring operating mechanism and disconnecting earthing switchgear integrate by chamber an interlock unit and a mechanism interlock unit. The chamber interlock unit, the mechanism interlock unit and a chamber lock plate form an integrative unit. The chamber lock plate is opposite to the buckle of the opening half shaft of the spring operating mechanism and is equipped with chamber lock pin. The chamber interlock unit moves up and down to open or close the operating crank hole of the disconnecting earthing switchgear, and corresponds to the closing operation and limit closing driven by buckle of closing half shaft and the limit and opening of opening half shaft and cable chamber.
