摘要： A system for adjusting a length of an insulating rod of a high voltage circuit breaker includes a clutch and a fitting. The clutch includes a thread with a given thread pitch, and the fitting includes a thread with a given thread pitch formed in coordination with the thread of the clutch. The fitting is adjustably coupled with the clutch by means of the threads and the fitting is configured to be fixedly coupled with the insulating rod such that with respect to an assembled state of the system with insulating rod and with respect to a longitudinal axis the length of the insulating rod is adjustable due to rotation of the clutch relative to the fitting.

摘要： A tank type vacuum circuit breaker uses a columnar or cylindrical insulation rod at a connection portion between an operating mechanism unit and a vacuum valve. The insulation rod is connected to the operating mechanism unit and the vacuum valve by rod-shaped pins. To prevent the insulation rod itself from falling, connection is made by shifting phases of the pins 90 degrees, respectively, each pin being connected to the operating mechanism unit and the vacuum valve. Accordingly, the falling of the insulation rod, the use of an insulation support tube and an insulation support for ensuring mechanical strength, are avoided. Further fastening of those supports by bolts or the like is not needed. Increases in the number of components, the size of the shape of assembly members around the insulation rod, and weight due to such increases, are prevented.

摘要： A piston rod includes a large-diameter portion that is formed on the side of a movable contact, and a small-diameter portion that is formed on the side of an insulating operation rod relative to the large-diameter portion, and that is formed with an outer diameter smaller than the inner diameter of an inner peripheral surface of an insulating cylindrical member. The insulating cylindrical member includes a cylindrical portion that is interposed between the outer peripheral surface of the small-diameter portion and the inner peripheral surface of the insulating operation rod, a bottom portion that is arranged opposed to the distal end of the small-diameter portion, and a through hole through which a coupling pin is inserted through the piston rod and the insulating operation rod.

摘要： An electrical switch includes a tubular housing that includes an interface positioned intermediate the conductor receiving end and the operating end. An operating rod extends through the housing. A fixed contact is electrically coupled to the operating end. A moveable contact is electrically coupled to the interface and the operating rod, wherein the moveable contact is moveable between a first position contacting the fixed contact and a second position separated from the fixed contact. A diaphragm is positioned in the tubular housing between the interface and the operating end and includes a first tubular portion and a second tubular portion. Movement of the operating rod from the first position to the second position causes the second tubular portion to move relative to the first tubular portion, thus deforming the shoulder portion.

摘要： The drive rod for high-voltage switchgear that is insulated with a dielectric gas comprises a segment made of an electrically-insulating material and two metal endpieces fixed to respective ends of the segment, as well as a thermal shield that is made of an electrically-insulating material, that is disposed between the endpieces, and that surrounds the insulating segment while being spaced apart therefrom to define an annular gap serving to be filled with the dielectric gas. In this way, the insulating segment of the rod is protected against thermal attack from electric arcs.
