Definitions
- the present invention relates to a cast resin transformer with at least one primary winding, at least one Secondary winding and at least one with cast connection element, that via a connecting wire to the primary winding or the secondary winding is electrically connected and to that, e.g. by means of screw connection, one transformer-external connecting line can be connected, wherein the connecting element has a hole for receiving the connecting wire has and the lead wire inserted into the bore is (DE-PS 29 04 746 corresponding to EP 0 014 418 A1).
- a magnetic coil unit is known the one cast in a casting compound together with the winding Connection elements mechanically firm and electrical Conductively connected to the winding via conductor bars are that these conductor bars are deformed in the manner of a Knurling.
- the connecting wires are also over Solder points connected to the conductor bars.
- Similar transformers are also used, for example, by Trafo-Union GmbH under the name GEAFOL cast resin transformers manufactured and distributed.
- the object of the present invention is a simple, reliable and inexpensive connection between to produce the connecting wire and the connecting element.
- the deformation is designed as a bulge.
- the bulge can be caused by upsetting what accommodates the simple manufacturability.
- the hole can as a blind hole or alternatively as a through hole be trained.
- the connecting element can advantageously be a threaded bore to hold a screw to connect the Have connection line with the bore radially or axially is arranged for tapping. This allows the cast resin transformer conveniently connected to the network become.
- the threaded hole and / or the hole can be advantageous be arranged eccentrically so that a lateral connection is possible.
- the connecting element preferably consists of Brass, whereby the connecting wire is preferably made of copper. This ensures good contact.
- the transformer 1 shows a three-phase transformer, the three primary windings 1 and three secondary windings 2, which each in pairs concentrically on the three columns 3 of the Transformer core 4 are arranged.
- the primary windings 1 are connected to the connecting elements 6 via the connecting wires 5 connected.
- the secondary windings 2 are over the connecting wires 7 connected to the connecting elements 8.
- a primary three-phase network with the phases R, S and T or a secondary three-phase network can be connected with phases U, V and W.
- the entire transformer including transformer core 4, windings 1, 2, connection elements 6, 8 and connecting wires 5, 7 in resin 11th poured. So from the outside there are only the connecting elements 6, 8 accessible.
- the windings can alternatively also each form encapsulated units that are based on a common, not potted core are arranged.
- connection elements 6, 8 are as hexagon cast nuts educated.
- the connection elements 6, 8 have each have a threaded bore 12, into which one in FIG. 2 Screw not shown is screwed. Means Such a screw connection becomes the transformer external Connection lines 9, 10 connected to the transformer.
- the connection elements 6, 8 also each have a bore 13, which in the cast state Connection elements 6, 8 is directed inwards and the Receiving the connecting wires 5, 7 is used.
- FIG. 2 it points into the bore 13 inserted connecting wire 5 in the area of the connecting element 6 a bulge 14 on.
- the bulge 14 can e.g. by Upset. Due to the bulge 14 is the Lead 5 mechanically fixed and electrically conductive with the connecting element 6 connected.
- the connection is both gas and liquid tight. It can absorb tensile forces and acts as a protection against twisting.
- the bulge 14 can, depending on the configuration of the bore 13 be designed differently. If the bore 13 is a simple one Is bore, bulge 14 is at the entrance to the bore 13 arranged. If the hole is half open or one Has bulge, the bulge 14 can alternatively or additionally in the half-open area of the bore 13 or be arranged in the puncture area of the bore 13.
- the bore 13 is axially to Threaded bore 12 arranged, both the threaded bore 12 as well as the bore 13 outside the line of symmetry Pouring nut 6, that is to say eccentrically. Thereby the pouring nut 6 can be kept compact.
- the bore 13 is in the present Case designed as a blind hole.
- the bore 13 could also be designed as a through hole.
- connection wire 7 shows a further embodiment of the connection between Connection wire 7 and connection element 8.
- the essential The difference from the first embodiment is that the Bore 13 not axially but radially to the threaded bore 12 is arranged. In this embodiment, too Bore 13 formed as a through hole. You could but, as shown in FIG. 2, also as a blind hole be trained.
- the invention described above is particularly advantageous when the connecting element 6, 8 consists of brass and the connecting wire 5, 7 made of copper. Especially with this one Combination is required for soldering flux, which can only be removed with great effort leaves. Other working methods such as welding or squeezing are against it for other technical reasons not possible.
