- Circuit breaker switching device with circuit breaker, method for operating a switching device
- the invention relates to power disconnect switches for high voltage networks, a switching device with a circuit breaker, method for operating a switching device and a use of a circuit breaker.
- Circuit breakers combine the function of a circuit breaker with that of a circuit breaker.
- Power circuit-breakers make it possible, for example, to connect or disconnect line sections or equipment of a high-voltage network under load or power.
- Isolating switch can be switched on operating currents or short-circuit currents and turn off ⁇ and establish a standardized separation in terms of a separation switch.
- Known power circuit breakers have an automatic mechanical interlock that locks the circuit breaker in the off state to ensure the separation function. Once such a circuit interrupter, changes from an on-state in which it connects conduit sections or resources with each other in a negotiated scarf ⁇ ended state in which it disconnects the line sections or equipment, of the power circuit breaker is locked in the ⁇ ser off position and locked.
- the automatic mechanical interlock has the disadvantage that a short interruption or quick activation, eg in the event of a fault, is not possible.
- Disconnector is not guaranteed. So far, the circuit breaker and locking system are separately controlled and fed back as two devices. The circuit breaker can be switched off and is reported back as switched off ⁇ . Subsequently, the circuit breaker ⁇ ter can be locked and is reported as locked. In this combination, a separation point is assumed safe.
- a disadvantage here is that the circuit breaker must be controlled and reported back on two ways.

- the circuit breaker can therefore be used for earthing purposes.
- unavoidable inductive and / or capacitive earth currents / voltages can be switched via the power disconnect switch, in particular during operation.
- Conventional earthing switches do not have this or only be ⁇ borders suitable.
- the locking device may represent a function lock for the switching element of the circuit breaker. As long as the locking device locks the switching element in a stored scarf ⁇ ended state or in the off state, the switching element can not by external means, such as
- the switching element of the circuit breaker as far as it is locked in the on or off state by the locking device can be released only by a release of the lock by the locking device for switching operations.
- the power disconnect switch has a detector which is set up to detect a switching position of the locking device and to emit end-stop-safe feedback. With the aid of the detector, it is therefore possible to provide feedback regarding the actual switching position of the locking device to a user
- the detector may be configured to detect a closed position of the locking device, in which the locking device blocks the switching element.

- There may be a separate detector or a separate sensor for a closed position of the locking device and for an off position of the
- the invention relates to a power disconnect switch for high-voltage networks, with a switching ⁇ element, with a locking device and a detector, wherein the locking device is adapted to lock the switching element in an open position of the switching ⁇ elements or release and wherein the detector is adapted to detect a shift position of the locking device ⁇ and dispense a endlagenticiane scrubmel ⁇ dung.
- the detector can output a feedback about the actual switching state of the locking device. For example, it can be detected whether the locking device has actually locked the switching element in its off position to monitor a reliable disconnection function of the circuit breaker.
- the locking device may have a mechanical locking element.
- the mechanical Verriegelungsele ⁇ ment may be, for example, a movable bolt or bolt, which is adapted to lock a movement of the switching element of a switch-off in a closed position, or vice versa.
- the mechanical locking element acts against a movement of the Wennele ⁇ ment in particular form-fitting manner.
- the locking device may have a first locking element for locking the switching element in the on state and a second locking element for locking the switching element in the off state.
- the locking device may be configured to mechanically and / or electrically and / or software or control technology to lock the switching element.
- a locking element may be configured to
- Switching element mechanically and / or electrically lock.
- a first locking element for locking the switching element ⁇ in the on state may be adapted to lock the switching element mechanically and / or electrically.
- a second locking element for locking the switching element in the off state may be configured to mechanically and / or electrically lock the switching element.
- the detector may be configured to detect an end position of a mechanical locking element of the locking device and ERS one endlagenrelie give feedback ⁇ .
- a tactile, optical, electrical or magnetic detection of the end position of the mecha ⁇ African locking element There may be provided to detect an end position of a mechanical locking element ⁇ African one or more sensors. So redundancies can be created to achieve a reliable monitoring of the locking device.
- the detector may be configured to detect a first end position in which the locking element blocks the switching element. Alternatively or additionally, the detector can do so be set to detect a second end position in which the Verriege ⁇ ment element releases the switching element.
- the locking device can be controlled separately from the switching element.
- the isolating switch control device can separate control elements for ON and OFF switching of the switching element and ⁇ be provided for locking and releasing the switching element. In this way, four different switching states or functions of the Leis ⁇ tung separating switch can be switched.
- a switching device for high-voltage networks is specified, with a Leis ⁇ processing circuit breaker which is designed in a manner described above, having a first terminal, a second terminal and a grounding means, said grounding means between said first terminal and the
- Switching element of the circuit breaker is branched off.
- the locking device is set up to lock or release the switching element in a closed position of the switching element, a reliable and reliable switching through of a grounding device produced by the grounding device can take place via the switching element from the first connection to the second connection.
- the first terminal may be a field terminal to which at ⁇ game as a busbar, a switchgear and / or a power transformer box is connected.
- the second connection can be a mains connection to which an overhead line, a cable, a cable or a gas-insulated cable is connected.
- An external system may be connected to the second connection so that the voltage applied to the second connection can not be controlled or switched by control or operating devices associated with the switching device.
- a grounding switch assigned to the grounding device can be disconnected from the second terminal before a switching operation by the switching element. So can one
- Switching load of the earthing switch can be avoided under load.
- a wear of the grounding switch is avoided by a suitable switching sequence ⁇ sequence . This can be achieved, for example, that a load by the switching element being switched on before ⁇ is the earthing switch is turned off.
- the switching device may comprise an auxiliary switch, wherein the auxiliary switch is coupled to the grounding device, the switching element and the locking device and wherein the auxiliary switch is adapted depending on a switching position of the grounding device, a switching command to turn on the switching element and / or release the locking device, and wherein the auxiliary switch, the grounding device and the switching element are coupled in such a way that the switching element in front of the grounding device is extended. is switched on, in particular, that a switching time of the switching elements ⁇ is less than a switching time of the Erdungseinrich ⁇ processing. In this way it can be avoided that power or load is switched by a grounding switch of the grounding device, so that the earthing switch is exposed to little wear.
- the switching time is in the present case, the time required for a jeweili ⁇ ger switch for making, breaking or disconnecting an electrical connection between two terminals associated with the switch. Because the switching time of the switching element is shorter than the switching time of the grounding device or of a grounding switch of the grounding device, it can be avoided that the grounding device or the grounding switch is switched under load or power, so that in particular no short-circuit or leakage currents pass through the grounding device or the earthing switch are switched. This increases the life of the earthing device or the earthing switch.
- a grounding switch of the grounding device may have a free path. This means that the earthing switch to be opened, starting from a turned-on state, starting from an end position ⁇ initially maintains the electrical connection over a predetermined opening or travel range. From the end position in the on state causes an opening movement of the switch along the idle path therefore no separation of the electrical connection. Due to the free travel, therefore, a dead time or dead time interval is specified after the signal for opening the grounding switch, in which the grounding continues to exist. Preferably, the dead time or dead time is greater than the switching time of the switching element. This avoids the ⁇ that the earthing switch is switched under load, so that in particular no short-circuit or leakage through the earthing switch are switched. This increases the life ⁇ duration of the grounding switch.
- the invention relates to a method for operating a switching device, wherein the following method steps are run through:
- the circuit breaker can be incorporated in a protective earth.
- a method is specified, with the method steps:
- Switching element is turned off. It can be provided that a locking of the switching element takes place automatically in the closed position, provided that the grounding device is turned on when switching the switching element. Thus, a malfunction when switching through a ground can be avoided.

- grounding can be switched off as follows: In an initial state, the grounding device is turned on ⁇ and the switching element of the circuit breaker is mechanically locked in its closed position.
