Definitions
- the invention relates to a selector for an on-load tap-changer and an on-load tap changer having a diverter switch and a selector.
- No. 6,693,247 B1 describes an on-load tap-changer which functions according to the reactor switching principle.
- the on-load tap changer has a base plate and a cover plate, between which a motor, a transmission and the contact device are arranged.
- the fixed contacts are arranged in a circle on the base plate and are connected by different contact units, which are operated via the transmission.
- the contacting of the fixed contacts with the winding tappings takes place on the back of the base plate.
- the gearbox is essentially attached to the cover plate, which is made of steel.
- a formulation of the type "A is attached to B” corresponds to a formulation of the type "A is connected to B"
- a formulation of the type "A is connected to B” means "A is directly conducting with B electrically conductive connected "and” A is indirectly, so via C, electrically connected to B “, and has a formulation of the type” A is connected to B “meaning" A is directly electrically connected to B ".
- the invention proposes according to a first aspect, a selector for an on-load tap changer with a diverter switch, comprising
- an insulating plate having a first side and a second, opposite side;
- a first terminal connected to the first moving contact and connectable to a first branch or load branch of the diverter switch
- Each moving contact can be selectively connected to each of the fixed contacts.
- this selector allows both moving contacts to make a fixed contact simultaneously in the stationary state.
- the entire on-load tap-changer is at a defined potential and thus has a high surge voltage resistance.
- This voter is inexpensive due to fewer components and still safe. All parts of the selector are attached to only one insulating plate. This particularly space-saving design makes it possible to considerably reduce the size of the corresponding transformer, which is designed, for example, as a local network transformer. This fact reduces the overall cost of a system. Furthermore, this simple structure allows a particularly fast assembly of the voter.
- the fixed contacts are easily inserted into the insulating plate. The installation of the moving contacts is also easy to carry out, as they are easy to install from every side.
- Each fixed contact can be connected or connected to an associated winding tap of a control winding of a transformer or a controllable coil.
- the moving contacts and fixed contacts are designed such that each moving contact can be selectively connected to each of the fixed contacts.
- This selector can be formed as desired in any manner, for example, such that it has at least one or no additional insulating plate and / or at least one or no additional moving contact and / or at least one or no additional connection.
- Each fixed contact on the first side has a first contact area for the first moving contact and on the second side has a second contact area for the second moving contact.
- the contact areas of the fixed contacts correspond to the geometry of the moving contacts and thus ensure an electrically conductive connection, which is in particular form-fitting.
- the contact areas may be formed, for example, as simple straight or curved pins.
- the voter includes
- a first Geneva wheel rotatably mounted on the insulating plate about an axis and carrying the first moving contact
- a second Geneva wheel which is rotatably mounted about the axis on the insulating plate and carries the second moving contact
- the axis is perpendicular to the two sides of the insulating plate.
- each moving contact can be fastened by additional means, such as compression and / or tension springs, on the respective Geneva wheel in order to ensure a movable or floating bearing.
- additional means such as compression and / or tension springs, on the respective Geneva wheel in order to ensure a movable or floating bearing.

- the voter includes
- a common drive shaft which extends through the insulating plate and the driver and is rotatably mounted on the insulating plate;
- the first driver has a first cam and the second driver has a second cam; -
- Each cam engages in the respective Maltese wheel, so that with a complete rotation of a driver, the respective Geneva wheel rotates only a fraction of a complete rotation.
- the drivers can have additional cams as needed, so that when turning a driver through 360 ° the respective Maltese wheel is operated accordingly more often.
- the selector may have at least one or no additional drive shaft as needed.
- the first cam is offset from the second cam, so that an alternate operation of the Geneva wheels takes place.
- the drivers and thus arranged on these cams are offset at an angle to each other. The angle is so great that an offset actuation of the individual moving contacts takes place.
- connections are connected to the moving contacts directly or via a stranded wire;
- the terminals are connected to a contact shaft and / or a contact ring; and or
- Each moving contact is formed one or more parts;
- Each moving contact is movably mounted on the respective Maltese wheel; and or
- Each fixed contact is connected to a line or with a line in one piece as a curved conductor is formed.
- the fixed contact and the line can be connected by soldering, welding or another joining method.
- both parts can also consist of a wire which has two contact areas for the moving contacts by deforming at one end.
- the lines are attached to the insulating plate by means of a retaining ring and / or a mounting rail; and or
- the lines are clipped to the insulating plate, plugged, snapped or snapped; and or
- the cables are embedded or molded or injected or melted in or on the insulating plate.
- the embedding of the lines in the insulating plate can be done as desired in any manner, for example by injection molding or low pressure casting.
- the first Geneva wheel is rotatably mounted on a first bearing axis
- the second Geneva wheel is rotatably mounted on a second bearing axis
- the bearing axes and the insulating plate are integrally formed.
