摘要： A tank-type circuit breaker includes a cylindrical grounded tank in which an insulating gas is sealed, a vacuum valve insulated and supported in the grounded tank and including a movable-side contact and a fixed-side contact, a movable conductor electrically connected to the movable-side contact, a fixed conductor electrically connected to the fixed-side contact, a movable-side external conductor and a fixed-side external conductor disposed in a pair of bushings extending above the grounded tank, a movable-side frame electrically connecting the lower end of the movable-side external conductor to the movable conductor, and a fixed-side frame electrically connecting the lower end of the fixed-side external conductor to the fixed conductor. The fixed-side frame and the fixed-side external conductor are connected via at least two springs arranged in series along an extending direction of the fixed-side external conductor, so that the fixed-side frame is suspended and supported by the fixed-side external conductor.

摘要： An underarm gang operated vacuum break switch (underarm switch) has an electrically live portion under a mounting arm, which provides advantages over the standard vacuum break switch, which have the electrically live portion above the mounting arm. Because the non-electrified mounting arm is above the electrified portion, the underarm switch is safer for perching birds and other wildlife. The nature of the underarm switch also provides other benefits including a disconnect blade that when opened creates a visual gap to ensure electrical discontinuity along with a safety locking arm tied to deactivating the underarm switch. Adding to the safety measures is a visual indicator that shows an electrician when the switch is live and safe to open the disconnect blade. Other safety measures include a shock absorber assembly and inertia slowing mass protecting electrical contacts within the vacuum break switch from failing.

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.
