- the arc is ignited exclusively in the closed chamber of the second interrupter unit and thus shielded from the outside ⁇ .
- a circuit breaker between the first interrupter unit and the second interrupter unit is arranged. Particularly in the case that the rated short circuit current for the first switch unit is greater than the rated short circuit current for the second interrupter unit, has the second switch ⁇ unit may be separated from the turned-on first switch unit. This electrical separation ensures the circuit breaker.
- a serial arrangement of the two sub-cup units can be used.
- the second switch unit according to the present, arranged ⁇ invention to the voltage applied to the switching device voltage potential side, in particular the high-voltage potential side by ⁇ .
- parallel to and / or serially to the second interrupter unit at least one further Un ⁇ terbrecherü arranged for the derivation of overvoltages.
- the third switch unit a surge arrester, egg ⁇ ne radio link, open or encapsulated or other chip nungsbegrenzer.
- the rated voltage of the second interrupter unit can be less than the rated ⁇ the first switching chamber are chosen voltage.
- the second interrupter unit is integrated in a fixed contact of an air-insulated earthing switch as the first interrupter unit.
- a first part of the housing located on a movable main contact
- Disconnector contact to the second part of the separation scarf ⁇ age ago By utilizing the movement of the movable main contact of the earthing switch as the first breaker ⁇ unit mechanical / electrical coupling by means of a nes first part of the circuit breaker is possible.
- a correspondingly designed "finger" engages in the receiving device, and provides a result of the movement of the breast box of the movable main ⁇ contact a connection on power or turned off forth.
- the receiving device performs a rotational movement. Short before reaching the end position for the switched state, the movable main ⁇ leads contact a stroke movement in the fixed main contact.
- DIE ser movement of the movable main contact is used to interrupt the existing electrical connection between the two parts of the circuit breaker again in the on state.
- the second interrupter unit In the end position of the movable main contact in the switched state, the second interrupter unit is therefore again electrically connected to the H by the opened disconnecting switch Main current isolated.
- the second interrupter unit is switched. With progressive movement of the movable main contact and removal from the fixed main contact, the connection between the fixed and the movable main contact is separated arc-free.
- the first part of the circuit breaker is dimensioned so that with a sufficient separation distance between the main contacts, the receiving device then opens the second interrupter unit, eg a vacuum interrupter chamber, due to the rotational movement. A resulting arc remains in the chamber of the second interrupter unit.
- the circuit breaker can also be opened without current. This sequence of movements is ensured by the coordinated geometry and design of the movable main contact, the length and arrangement of the first part of the separator ⁇ switch, and the design of the recording device.
- the second interrupter unit paral lel ⁇ or in series with the first switch unit verbun ⁇ .
- the current strengths of the two interrupter units must each be designed with respect to the maximum currents.
- the current stability of the second interrupter unit may be smaller than the first interrupter unit.
- a method for switching ei ⁇ nes air-insulated earthing switch is also provided, wherein the air-insulated earthing switch is connected to a to luftiso ⁇ profiled earthing switch arranged in parallel with the second interrupter unit, wherein said second interrupter unit when connecting the electrical line in front of the air-insulated earthing switch is closed and when Disconnect the electrical line first the air-insulated earthing switch and only then the second interrupter unit is separated from the e- lectric line.
- the Trennstel- Ie When using a separation point as the connection between the air-insulated earthing switch and the second interrupter unit, the Trennstel- Ie, then the second interrupter unit, then the air-insulated earthing switch is closed at the power-on and the separation point is reopened when hergestell ⁇ ter line connection.
- the opened separation point When switching off the opened separation point is first ge ⁇ closed, then opened the air-insulated earthing switch, then opened the second interrupter unit under any occurring generation of an arc and opened the separation point again after the complete separation of the electrical line.
