Definitions

the invention relates to a high-voltage winding of an inductive voltage converter with at least two partial windings coaxially encompassing one another and an intermediate electrode located between the partial windings, which protrudes laterally from the high-voltage winding with edge regions present on both sides of a central region located within the high-voltage winding.
the intermediate electrode consists of a wrapped metal sheet, for example made of copper or a copper alloy.
the intermediate electrode serves as a winding body for the outer partial winding comprising the (inner) partial winding.
the invention has for its object to provide a high-voltage winding, which is characterized by a particularly stable and vibration-resistant winding structure.
the intermediate electrode in the case of a high-voltage winding of the type specified at the outset, consists of two metal, half-ring-shaped shell parts which have holes in the central region; the shell parts, with the release of two gaps, the one (inner) partial winding on the outside and are pressed against the one partial winding by the wound up further (outer) partial winding, and one of the two gaps is bridged by means of a contact element.
a major advantage of the high-voltage winding according to the invention is that due to the use of an intermediate electrode with holes in its central region, a stable and vibration-resistant winding structure is achieved, because the shell parts are, as it were, under the pressure of the wound outer part winding with their holes in the outer insulation of the inner part winding hook, so that the intermediate electrode with the outer part winding wound on it is neither laterally nor in the circumferential direction with respect to the inner part winding.
This interlocking of the intermediate electrode is made possible by the fact that it consists of two half-ring-shaped shell parts with a dimensioning such that it encompasses the inner partial winding while leaving two gaps free and can thus be pressed against the inner partial winding unhindered by the outer partial winding.
the contact element which bridges one of the gaps, ensures that the entire intermediate electrode is at the same boiling potential, a short-circuit turn being prevented in a known manner by means of the second, not bridged gap.
the invention is applicable not only to a high-voltage winding with two partial windings coaxially comprising one another, but also to high-voltage windings which consist of more than two partial windings;
the auxiliary electrode between the respectively adjacent partial windings is then to be designed in the manner described above, and its dimensioning to achieve the gaps and the use of a contact element must also be carried out in a corresponding manner.
the high-voltage winding according to the invention with at least two partial windings designed as layer windings is particularly advantageous if the shell parts in the central region have an annular, bead-like indentation with a width of Winding layers of the partial windings designed as rectangular windings have a corresponding width and if each partial winding has foils carrying thermoplastic lacquer between their winding layers, the width of which is greater than the width of the winding layers and is pinnated on their sides protruding from the winding layers, the protruding sides overlapping one another are folded over on the outside and the foils are bonded to the winding layers and to one another due to the effect of heat on the lacquer layer.
Such a high-voltage winding has the advantage that it is particularly stable and vibration-resistant, since it not only has a fixed winding structure with regard to each partial winding due to the use of thermoplastic lacquer-carrying foils and the effect of heat, but also due to the use of shell parts with a bead-like indentation in the Central area ensures a firm mounting of the intermediate electrode and thus the outer part winding applied to it on the inner part winding. Even high loads on the winding in the direction parallel to the axis therefore do not lead to destruction of the winding structure.
a layer winding with foils carrying thermoplastic lacquer, which are glued to the winding layers and to one another due to the action of heat on the lacquer layers, is known per se from DE-GM 81 27 B60.
the contact element can be designed in different ways. It is considered to be advantageous if the contact element contains a first contact strip lying on the inside of the shell parts, which is connected to the outer end of the inner partial winding, and has a second contact strip, lying on the outside of the shell parts, which is connected to the inner end of the outer partial winding and when the contact strips are connected to one another in the region of the bridged gap.
the contact element is one in which two initially separate contact strips are used, then these are advantageously connected to one another by welding in the region of the bridged gap.
the contact strips advantageously consist of a single contact strip which is guided through the gap; the first contact strip is bent in a meandering manner in the area of one shell part and the second contact strip is bent in a meandering shape in the area of the other shell part.
the contact strips are in the area of their connection have with the ends of the partial windings have transversely extending fastening tabs, each of which is fixed with one part by means of the foils in the edge region of the partial windings and can be folded over with the other around the foils.
a high-voltage winding 1 consists of an inner partial winding 2 and an outer partial winding 3; both partial windings 2 and 3 are designed as a layer winding, specifically as a rectangular winding.
Each partial winding 2 or 3 is made as described in DE-GM 81 27 860 in detail.
a plastic film 5 with a thermoplastic lacquer layer which is pinnate at its edges, is used as the insulating material web between the winding layers 4 with the same width. These plastic films 5 are located between the individual winding layers 4.
the partial winding 2 is applied to a straight-cylindrical bobbin 7.
the inner partial winding 2 is surrounded by an intermediate electrode 9, which has an annular, bead-like indentation 11 in its central region 10, as a result of which the intermediate electrode 9 after the completion of the entire high-voltage winding (see below) is positively in the inner part of the winding 2.
each metal, half-ring-shaped shell part 12 or 13 of the auxiliary electrode 9 has holes 14 in its central region 10.
each intermediate electrode 9 is provided with edge regions 16 and 17, which are widened in a trumpet shape to avoid field concentrations.
the half-ring-shaped shell parts 12 and 13 of the intermediate electrode 9 are dimensioned such that after they have been applied to the inner partial winding 2 they form two gaps, of which a gap 1B can be seen in FIG.
the outer partial winding 3 is applied to the central region 10 of the intermediate electrode 9.
the outer partial winding is constructed in the same manner as has already been described in detail in connection with the explanation of the structure of the inner partial winding 2.
the latter is subjected to a heat treatment, the feathered edges of the plastic films 5 sticking to the outer turns of the winding layers 4 and to the respective adjacent edges of the plastic films 5 due to the thermoplastic change in the heat, whereby a solid structure of the layer winding is guaranteed even without a lateral delimiting part of the coil body even with larger loads on the layer winding.
the individual partial windings 2 and 3 bake firmly with each other, and there is at the same time an intimate connection of the central region 10 of the intermediate electrode 9 with the two partial windings 2 and 3 due to the bead-like indentation 11 and the holes 14, so that the high-voltage winding 1 is very stable and very vibration-resistant. This property arises, among other things, because the partial windings 2 and 3 contract more when exposed to heat in the central region than outside, so that protruding edges 19 and 20 are formed which hold the intermediate electrode 9.
the high-voltage winding 1 generally comprises a secondary winding 21, which in turn is arranged on an iron core 22, which can be a frame core.
the high-voltage winding 1 can be surrounded by a high-voltage electrode in a manner not shown.
FIGS. 3 and 4 serve to explain the contact element of the high-voltage winding according to the invention. They show a contact element 30 which has a first contact strip 31.
This first contact strip 31 is arranged inside the shell parts 12 and 13 of the intermediate electrode 9 and has one end 32 connected to the outer end 33 of the inner partial winding 2.
the contact strip 21 is bent at its other end 35 in a meandering shape.
the contact strip 31 is part of a contact strip 36, from which a second contact strip 37 is also formed.
the contact band 36 is therefore guided through the gap 18 between the shell parts 12 and 13 to the outside.
the second contact strip 37 is connected at its one end 38 to the inner end 39 of the outer partial winding, which is not shown, and is bent at its other end 40 in a meandering shape.
the area of the second contact strip 37 which is bent in a meandering shape lies outside the shell part 13. In this way it is achieved that - if there is heat action should result in a gap between the shell parts and the partial windings - in any case a contact between the contact strip 26 and the two shell parts 12 and 13 results, so that they are at the same potential.
the contact strip opens in the area that is bent in a meandering manner and thus ensures contact.
each contact strip 31 or 37 is in the region of its connection point 41. 42 with the ends 33 bzu. 39 of the partial windings 2 and 3 are provided with a transversely extending fastening tab 43 and 44, respectively.
This mounting tabs 43 bzu. 44 iron a turnable part 45 bzu. 46 so that a mechanical fixing of the entire contact element with the insulation of the partial windings or the plastic film is possible. This is done in that after completion of the inner partial winding 2, the lower part 47 of the fastening tab 43 in FIG. 4 is wrapped with plastic film after the connection point 41 has been produced, the entire remaining part of the contact element being folded sideways (to the right).
the entire remaining part of the contact element is then folded back, and the shell parts 12 and 13 are applied, the contact strip being guided outwards through the gap 18 in the manner shown in FIG. 3.
the part 46 of the fastening tab 44 is folded outward (to the left) and the plastic film of the winding insulation of the outer partial winding 3 is applied to the other part 48 of the fastening tab 44 so that the contact element in the area outside the shell parts 12 and 13 is mechanically fixed.
the part 46 is folded back, the connection is made to the inner end 39 of the outer part winding 3 and then the entire outer part winding 3 is produced in the manner already described.
a high-voltage winding 1 is then obtained, the shell parts 12 and 13 of which ensure firm mechanical cohesion of the partial windings 2 and 3, are at the same potential and prevent a short-circuit turn due to a gap which is not bridged.
