An actuation system of a vacuum bottle for an electrical connection device, the vacuum bottle including one movable electrode and one fixed electrode, the movable electrode being movable longitudinally between a closed position in which the two electrodes are in contact with each other and an open position in which the two electrodes are separated. The actuation system includes an adjusting nut linked to the movable electrode and capable of rotation for adjusting its position in relation to the movable electrode, a driving device acting on the adjusting nut for driving the movable electrode towards the open position, and a locking device for locking the position of the adjusting nut in relation to the movable electrode.

The present disclosure provides a gas-insulated vacuum load break switch, including a high-voltage conductive loop having three phases independent from each other and of the same design, a control operating mechanism, a support box and a transmission apparatus. Each phase of the high-voltage conductive loop includes a load break switch unit with a vacuum interrupter, an isolating switch unit with an isolator, a plastic housing supporting the load break switch unit and the isolating switch unit, and an earthing switch unit; the control operating mechanism includes an operating mechanism for controlling the load break switch unit, an operating rod for controlling the isolating switch unit, and an operating mechanism for controlling the earthing switch unit.

A fast earthing switch for a GIS, including a movable contact rod, having an end; a cylinder, fixed to the contact rod and forming a gas chamber around at least part of the contact rod, the gas chamber including an outlet around the contact rod so that gas can flow along the contact rod and its end when it moves from a closed to an open position; and means for actuating the contact rod between a closed and an open position.

The 3-way disconnector and an earth switch for a gas insulated switchgear includes: a movable portion including a disconnector movable portion and an earth switch movable portion; a disconnector mover and an earth switch mover installed in the disconnector movable portion and the earth switch movable portion so as to be linearly movable; a driving lever rotatably installed between the disconnector mover and the earth switch mover; and a first lever and a second lever rotated by receiving a rotational force of the driving lever, and configured to move the disconnector mover and the earth switch mover, respectively, wherein a driver is protruded at one side of the driving lever, and a driving pin is provided at an end of the driver, and wherein the driving pin is configured to selectively move one of the first and second levers.

An electrical switch includes a pivotally supported blade, a toggle mechanism, and an operating mechanism. The operating mechanism is drivable in a first direction to pivot the blade about a first axis and toward a closed blade position. When pivoting toward the closed blade position, the toggle mechanism inhibits the blade from pivoting about a second axis. Upon reaching the closed blade position, continued motion of the operating mechanism in the first direction causes the toggle mechanism to pivot the blade about the second axis toward a closed contact position. In the closed contact position, the blade contacts at least one blade contact to electrically connect the blade and a first electrical terminal.

A device having one or more switching mechanisms configured to disconnect a power supply from a load; and one or more disconnector and earthing switches, each disconnector and earthing switch associated with a respective switching mechanism. Each disconnector and earthing switch comprising a telescopic disconnector blade, wherein the disconnector blade is configured to pivot around a first end between three different positions. The three positions comprise: a first position in which the disconnector and earthing switch is closed and the power supply is connected to the load through the disconnector blade; a second, isolation, position in which the disconnector and earthing switch is open and the power supply is disconnected from the load; and a third position in which the power supply is disconnected from the load and a second end of the disconnector blade is electrically connected to an earthing contact.

A current switch including a main contact including an electrically conductive knife, and an electrically insulating element, fitted in a mobile manner on a first portion of electric line in order to alternatively follow an opening movement and a closing movement; a shunt branch including a first part electrically connected to a second portion of the line, including a vacuum interrupter configured to be actuated alternatively between an open state and a closed state, a second part fitted in a mobile manner on the first part and configured to actuate the vacuum interrupter. During the opening movement, the electrically conductive knife acts upon the second part in order to actuate the vacuum interrupter, and during the closing movement, the electrically insulating element acts upon the second part without actuating the vacuum interrupter.

A power distribution switchgear including a housing to which a switch is mounted, housing has an opening, the first and second electric contact connected to a first and second conductors. A rotating operating shaft of inserted into the opening, and an actuator having a first end coupled to the shaft and a second end coupled to the second contact. The actuator and shaft made of an electrically insulating material. The shaft supported in the housing by the actuator member. The interface is located at a distance D from the longitudinal axis Y of the shaft that is longer than a distance d between axis Y and a circumferential edge that delimits the opening.

An electrical assembly has an isolator function, a circuit breaker function and at least one ground electrode function. The at least one ground electrode function, the isolator function and the circuit breaker function are integrated in one and the same module. A locking unit is integrated in the module. The locking unit subjects the isolator function, the circuit breaker function and the at least one ground electrode function to mutual interlocking.
