Definitions
- the present invention relates to a contact unit for switching between
- Winding taps of a control winding of a tapped transformer are particularly preferred in electrical switching devices of
- Winding taps of the control winding of the tapped transformer is completed without load current.
- Dial column arranged arranged connecting lines have become known.
- DE 27 54 682 proposes that the contact bridge housing supported by the inner drive tube is fastened to the inner drive tube by means of an arcuate projection adapted to the tube diameter and arranged above and below the contact bridge, and that both these arcuate projections as well the contact bridge through its own in the outer
- the actual contact element is designed as a contact bridge in DE 27 54 682, which produces an electrically conductive connection between the current ring assigned to it on the one hand and the selector terminal contact on the other hand.
- the contact element is arranged in a fixedly connected to the drive tube contact bridge housing and thus difficult to access in case of maintenance, or interchangeable. In addition, the assembly of the entire contact assembly for the manufacturer is cumbersome and time consuming.
- Object of the present invention is to provide a contact unit for switching between winding taps a control winding of a tapped transformer, which is easy to install and can be replaced quickly and easily in case of maintenance.
- This task is performed by a contact unit for switching between
- Winding taps of a control winding of a tapped transformer solved according to claim 1.
- the subclaims relate to particularly preferred developments of the invention.
- the general inventive idea is to accommodate the contact element of the contact unit in a separate contact housing, so that the contact element and the contact housing form a separate assembly and that the contact housing
- Recess are fixable by means of a retaining element.
- the contact housing is designed as a container which is open on two opposite sides, namely a front side and a rear side, and has a flange-like shielding ring in the region of the front side, on the outer circumference of the contact housing.
- the contact housing for resilient mounting of the contact element on an upper side and / or underside each pen provide that penetrate the top and / or bottom of the contact housing and be arranged between the contact element and the spring springs compression springs.
- the spring holder has a groove with a groove bottom and a wedge-shaped ramp.
- the holding element may be U-shaped, have a headband and hollow leg formed.
- the headband can also be designed to positively engage in the latched state of the separate module and contact in the groove.
- the legs of the retaining element can each further be provided a compression spring, each with a bolt provided on a cover
- a slot may be provided, in which a pin fixed to the contact housing engages, the contact element may be formed as an existing of several individual contacts blade contact protruding in its longitudinal dimension on both sides out of the contact housing.
- the contact holder has at least one opening in which a receiving means, preferably a pultruded rod, can be received.
- the receiving means may also be formed from hard paper or hard tissue.
- Figure 1 a is a schematic representation of a contact unit
- Figure 1 b is a detail view of the contact unit
- Figure 2a is a detail view of a contact housing with contact element
- Figure 2b is a side sectional view of the contact housing with contact element
- Figure 3 is a further side sectional view of the contact holder with
- FIG. 1 a shows a schematic illustration of a contact unit according to the invention by way of example for a three-phase application in a selector or diverter for a tapped transformer.
- Such electrical high-voltage switching devices such as voters or diverters are known in the art for decades and are used for current and voltage-free switching between winding taps of a control winding of the tapped transformer.
- Each of the contact unit according to the invention shown in Figure 1 a in this case has a contact holder 1 which can be fastened to at least one pultruded rod, which serves as a receiving means 2 for the corresponding contact unit.
- two substantially parallel bars arranged as receiving means 2 are provided. It is also conceivable within the scope of the invention, in the number, the geometric cross section, the geometric positioning of the
- the Contact holder 1 may be formed as an injection molded part or as an SMC part and have a content of, for example, 50% glass fiber mixture.
- the contact holder 1 is an electrically non-conductive component.
- the contact holder 1 is preferably formed in one piece and provided for mechanical fixation, each with an opening 3 for each of the receiving means 2, in which the corresponding receiving means 2 is inserted and held firmly by means of fixing elements 4. Shown are two openings 3 in Figure 1, in which the two serving as receiving means 2 rods are inserted.
- fixing elements 4 for example, thermoplastic bolts with snap-in lugs can be used for single-time use.
- Recesses 5 arranged. However, it is also conceivable within the scope of the invention to provide the openings 3 to the left of the recesses 5 or alternatively between the openings 3. This is ultimately dependent on how the inventive
- Contact unit must be installed in a selector or diverter, or as a particularly space-saving wiring of the fixed contacts of the corresponding
- Plastic, manufactured contact housing 6 is formed as a substantially cuboidal container, which on two opposite sides, namely on a
- the contact housing 6 provides two spring holders 10. 1 and 10. 2 at an upper side 6.3 or lower side 6
- FIG. 3 shows in a further sectional side view of the contact holder 1 with inserted contact housing 6.
- the holding element 8 with the arranged in the hollow legs 18.1 and 18.2 compression springs 19.1 and 19.2 and the cover 20 with the bolts 21.1 and 21.2 of the recess 5 of Assigned contact holder 1 and mechanically fixed by means of the fixing bolts 22.1 and 22.2 in the recess 5.
- this assembly is inserted into the recess 5 of the contact holder 1, in which its associated components, namely the support member 8, the compression springs 19.1 and 19.2, the cover 20 and the fixing bolts 22.1 and 22.2, in the arrow direction.
- the retaining bracket 16 slides from the rear side 6.2 in the direction of the front side 6.1 on the upper or lower side 6.3 and 6.4 via the spring holder 10.1 and subsequently over the ramp 15 until the retaining bracket 16 latches in the groove 14.
