- the partial decoupling of the movement of the first moving contact and the second moving contact in the main current path ensures that the required isolation distance between moving contacts and fixed contacts is always maintained, while at the same time ensuring a more compact structure. It is preferred that the first moving contact is firmly connected to the rotation axis or the first control means and thus always moves synchronously with the rotation axis or the first control means.
- the second control means together with the first control means, causes the third control means to move the arc-extinguishing contact in different directions of rotation about the axis of rotation through the first control means and the second control means to different positions of the first moving contact.
- first control means with a first control profile and the second control means with a second control profile control the position and movement of the third control means via a third control profile arranged on the third control means.
- the interlocking of the control profiles enables a complex sequence of movements of the first moving contact and the second moving contact without unnecessarily increasing the complexity of the drive.

- control electrodes are arranged in such a way that a dielectric strength is applied to the respective control electrodes Contacts is increased.
- control electrodes are formed from a conductive material and are coated with an insulating layer. This increases the dielectric strength of the commutation distance and also ensures that no pre-ignition arc ignites on one of the control electrodes when it is switched on.
- first moving contact is designed as a first moving contact widened at an end pointing away from the axis of rotation in such a way that the widened first moving contact both the main current path fixed contact and the Ne at a transition between the first main current path fixed contact and secondary current path fixed contact Benstrompfadfest Quiltitch touched at the same time, so electrically contacted.
- the widened first moving contact has one or more slots, in particular longitudinal slots, at least at the end facing away from the axis of rotation, so that the first moving contact when entering or leaving the first main current path fixed contact and / or the second Main current path fixed contact and / or secondary current path fixed contact is less stiff and prevents or reduces bouncing of the first moving contact when it hits the first main current path fixed contact.
- Switchgear especially medium or high-voltage switchgear, with a three-position switch according to one of the above versions.

- the required isolating distance is created using a knife system, the moving contacts in the main current path in the gas space.
- the opening of the vacuum tube that is, the opening of the arc extinguishing contacts of the arc extinguishing device, and thus switching off the current is initiated.
- the first movement contact moves on one of the auxiliary current path fixed contact associated with the arc extinguishing movement contact of the vacuum tube, a sliding contact, such as the first main current path fixed contact, the second main current path fixed contact and the earth fixed contact.
- the vacuum tube is only loaded with electricity for the short time it is switched off.
- the switch-on strength and continuous current carrying capacity is guaranteed via the main current path, which, as previously known, is designed for the busbar and cable outlet connection via a moving knife system, the moving contacts, and two fixed contacts, the first main current path fixed contact and the second main current path fixed contact.
- the vacuum tube opening is kinematically controlled by a first control means and a second control means, for example a Cam, and a third control means, for example a lever or means provided with a lever accordingly to the rotary position of the switch blade system, the moving contacts controlled.
- a first control means and a second control means for example a Cam
- a third control means for example a lever or means provided with a lever accordingly to the rotary position of the switch blade system, the moving contacts controlled.
- the moving bolt of the vacuum tube which is connected to the arc extinguishing contact that carries out the lifting movement, preferably consists of a one-piece rod with a puncture or a taper or constriction into which the lever engages at the interface to the lever. This saves additional components and results in a cost-effective and reliable mechanical connection.
- the moving bolt is electrically connected to the fixed auxiliary current path contact via a flexible current band.
- power cords are screwed onto the vacuum tube bolts.
- the auxiliary current path is subject to lower requirements with regard to electrical conductivity.
- connection of the current band to the vacuum tube such as clipping or clipping via a clamp effect, similar to shaft securing elements, a plug connection, or a push-button connection of a 9V battery or an ESD spiral cable.
- the current band in the area of the A stab in the moving bolt of the vacuum interrupter is designed as a spring-loaded, pretensioned clamp, and makes contact with the planar surfaces of the bolt with a defined biasing force.
- the lever is located within the clip geometry. The lever force acts when it is actuated always over the current band on the bolt of the vacuum tube. During actuation, this increases the pressing force of the live parts on one another and thus improves the electrical contact.
- This connection described has the advantage of a quick, simple but also error-free assembly. It decouples the current band from the rotational alignment of the vacuum tube around its own axis and therefore does not require any additional measures to prevent the
- the second control center e.g. B. a flap, provided as an extension of the first control means, the cam, which only comes into effect when egg ner activation, and the cam is extended.
- this flap is swiveled away from the kinematic function by the lever.
- the earth position can be achieved by switching to the "OFF" position. This results in a switch with the known three switching positions on /
- the flow of current from the main current path to the secondary current path should take place without interruption.
- Control electrodes arranged in contacts increase the dielectric strength of the contacts to one another.
- the conductive control electrodes are also coated with an insulating layer. This increases the dielectric strength of the commutation distance and also ensures that no pre-ignition arc ignites on one of the control electrodes when it is switched on.
- a widened first moving contact is suitable, for example a widened switch blade, which is geometrically able to briefly contact both contacts simultaneously.
- the fixed auxiliary current path contact only carries the rated current for a short time and is designed as a sliding or sliding contact, the pressure should be applied to reduce wear
- Switching knife on the bypass path fixed contact lowered. This can be done via a thinner design of the secondary flow path fixed contact compared to the first main current path fixed contact, the second main current path fixed contact and the fixed earth contact, or via a separate contact point with less pressure.
- the contact can also be made radially or from the outside on the moving contacts.
- the fixed bypass path contact can be made movable. This has the advantage that the switch blade is narrower and the fixed auxiliary current path contact is more compact. leads can be. Depending on the overall design of the switching device, this can lead to a smaller design.
- the fixed bypass path contact must be moved along with the switch blade during switch-off until the vacuum tube has switched off the current. The design must be such that the distance between the secondary contact including the switch blade and the busbar contact increases sufficiently quickly to be voltage-proof against the overvoltages that occur during a switch-off.
- This principle of the contact extension can be transferred to the cable outlet contact in the same way with a double-breaking isolator.
- the first moving contact e.g. the corresponding switch blade
- the first moving contact for mechanical decoupling of the two moving contact contact surfaces of the first moving contact, slotted long, that is, radially in relation to the circular movement of the switch blade.
- the first moving contact experiences a pre-alignment via the auxiliary current path fixed contact before it makes contact with the busbar.
- the widening of the first moving contact while driving over and leaving the auxiliary current path has no fixed contact due to the longitudinal slot
- the contact pressure force and the drive-up dynamics on the first main current path fixed contact behave autonomously in relation to the contact with the auxiliary current path fixed contact.
- the switching device must realize the three switching positions on / off / earth and provide a dynamic intermediate position for switching off the power. At the same time, it requires larger voltage distances compared to SF6-insulated switchgear.
- the moving contacts are designed to rotate centrally and with double interruption.
- the moving contacts contain a joint in order to enable a kink, and thus an optimal division of installation space, but also different movement sequences of the individual moving contacts.
- the first moving contact which goes through the commutation, is here directly connected to the axis of rotation, the main rotor.
- the second moving contact also referred to as a secondary switch blade, is intended to have a fixed path contact during a switch-off until after the current flow on the second main current has been switched off, e.g. the cable outlet contact, remain. Only then should the second moving contact be engaged and follow the movement of the axis of rotation, the main rotor.
- This control is implemented through the interaction of a control bolt and at least two cam tracks.
- One of the cam tracks is located on an immobile component, e.g. Support structure, e.g. a partition.
- the second cam track is located on the first control means, which is firmly connected to the main rotor.
- the two cam tracks each have an individual course, are arranged next to one another in parallel planes and at all times form a common overlap in which the control pin is located.
- the movement of one of the components causes the curves to move relative to one another. Due to the Relativbe movement, the common overlap is shifted at will according to the design of the cam tracks.
- the course of the cam tracks can be designed in such a way that the joint intersection of the cam tracks stops, makes its own movement, or moves exactly with the moving part.
- the control bolt always follows the common overlap and can be used to take along, move or stop another component yourself. This enables any coupling and decoupling of a component to the main rotor.
- the control bolt moves the second moving contact.
- a radially arranged elongated hole is introduced into the second moving contact around the control pin.
- the cam control is symmetrically mirrored or doubled around the center of the phase.
- the advantage of the switching kinematics described is in particular the use of an inexpensive vacuum load interrupter that is not switch-on-proof and is only designed for switching off.
- the tube has no or only low requirements in terms of switch-on strength, surge current conditions or even continuous current carrying capacity.
- the current flow in the secondary current path is limited only to the short period of time during which the current is canceled.
- the use of copper in the secondary trumpet can be reduced, which in turn brings cost advantages.
- the arrangement of the first control means, the flap, in the second control means, the main rotor, which varies the kinematics between switching on and off, enables a simple and compact design and a dielectrically interference-free un placement of a return spring on the electrical potential of the moving contacts.
- the breaking arc is only located in the tube. This minimizes the wear and tear on the isolator contacts, since there is no erosion on the contacts due to the arc when switching off.
- the joint between the moving contacts e.g. The switching knife assembly, in combination with the cam track control of the second moving contact, enables different movement states of moving contacts depending on the switching angle, despite only one drive movement. This enables previously contradicting movement states, thereby moving contacts
