A switch including a housing, a first contact arrangement having a first commutation contact element and a first contact, a second contact arrangement having a second commutation contact element and a second contact, and also a nominal contact arrangement. The first commutation contact element and the second commutation contact element form a snap-action connection with one another in the closed position of the commutation contact element. When the switch is closed, a distance between the first contact and the second contact is smaller than a distance between the first commutation contact element and the second commutation contact element in the direction of the axis.

Switch and method for disconnecting a switch

A switching device includes a switching element movable from a first position into a second position, a drive unit producing a rotary movement, and a flexible shaft transmitting the rotary movement to the switching element. The shaft has rotatable input and output sections on input- and output-drive sides, respectively. During movement of the shaft, a first rotary angle is producible at the output section, which first rotary angle is less than a second rotary angle at the input section at the same time, such that a first rotary angle shift is produced. The input section is connected to a switching position detection element having a control means with a first region which corresponds to the first position of the switching element and is coupled to the detection element. An identical indication of the detection element can be achieved in case of different rotary angle shifts in the same electrical switching state.

Switching device with a switching element driven via a flexible shaft

A gas-insulated switchgear assembly having a first module and a second module, which each have a gas area, which is in the form of a pressure vessel, is filled with an insulating gas and has at least two phase conductors. The first module is connected to the second module such that the first gas area and the second gas area are hydraulically separated from one another by an insulating body, while the phase conductors in the first module are electrically connected to the phase conductors at the same electrical potential in the second module. The at least two phase conductors in the first module can be electrically connected to the at least two phase conductors at the same electrical potential in the second module, in each case via a detachable plug connection.

Plug-in primary power connections of two modules of a gas-insulated high-voltage switchgear assembly

An exemplary switch having a housing that includes one contact bolt per phase. Each contact bolt moving along a longitudinal axis. In a first position on the axis, the contact bolt connects two active parts to one another. In a second position on the axis, the contact bolt is connected to a fixed earthing contact piece. A drive motor actuates the contact bolts via a drive spindle. The lines of movement of each contact bolt all phases lie in a common plane, wherein each contact bolt is driven by one insulating spindle, which is aligned with the line of movement. The drive spindle lies in the plane of the lines of movement and runs perpendicular to the insulating spindles and is coupled to each insulating spindle via a respective deflecting gear mechanism. The deflecting gear mechanism for the drive of the contact bolts is accommodated in the earthing contact pieces.

Metal-encapsulated, gas-insulated, combined switch disconnector and earthing switch

Exemplary embodiments are directed to a metal-encapsulated, polyphase busbar switch disconnector and earthing switch, including a housing which, on each of opposite sides has three flanges that lie on a plane. Each flange being connected to one busbar and, on a third side, a flange is connected to a circuit breaker. The circuit breaker having conductor elements arranged in an interior of the housing. First conductor elements are connected to the busbars, and second conductor elements are connected to circuit breaker poles. The second conductor elements are aligned at right angles to the first conductor elements, which connect the busbars to one another, such that the first conductor elements are substantially U-shaped and are passed around the second conductor elements. A switch disconnector and earthing switch contact arrangement is provided between an inner housing wall and the first and second conductor elements.
