Description

In the main patent 934 96o a winding for transformers., Choke coils and the like. High amperage proposed, consisting of individual disc coils with several parallel conductors with each coil only a fraction of a turn contains the parallel head and in which the head is stacked like a scale are arranged. The winding is turned upside down from reel to reel, so that the entire winding can be carried out without soldering points. There already in every spool every parallel conductor runs through the coil evenly from bottom to top every conductor exposed to the leakage flux in the same way, and also have this all parallel conductors are always the same length. This is how you get one well-twisted winding, the additional losses of which are a minimum. The parallel The conductors are all led to a collecting ring, from which the conductors are then fed lead to the powered circuit.

In order to expand the range of use of such a winding arrangement, is proposed according to the additional invention, the parallel conductors individually or in groups from the outside in series or partly in series and partly in parallel, where the total number of conductors in parallel is a single or multiple of the groups.

The collecting rings at the ends of the winding are made in so many Parts disassembled, as groups exist, in order to be able to connect the To get derivatives and a good close to the core.

To improve the cooling and insulation of the wires from one another channels are also arranged between the conductors, which also reduces the manufacturing process the transition from coil to coil is made much easier.

The coil arrangement according to the additional invention thereby secures with difficult demands, such as those in winding groups in; any series parallel connection occur without special precautions an even power distribution and cheap Cooling conditions so that good material utilization is achieved.

An exemplary embodiment according to the invention is shown schematically in the drawing shown.

The winding should, for example, have thirty turns with twelve parallel wires each, distributed over one hundred and twenty continuously wound disc coils. own. Coils 1, 2, 3 and 4 show the first, second, third and fourth coils of the winding. Each of the twelve parallel wires makes 1/4 turn per coil, so that after running through four coils a whole turn or after running through one hundred and twenty coils the prescribed thirty turns are achieved. Since every wire changes its position in the coil from inside to outside or outside to inside in the same way after every 1/4 turn, the radial twisting of the winding is good. A pairing circuit of all twelve wires or a group circuit, e.g. B. 2 X or 3 X or 4 X or 6 X or 12 X 30 turns is therefore easily possible. Has the voltage / winding z. B. 33.3 volts, the result is voltages of 1000, 2000, 3000, 4ooo, 6ooo or 12,000 volts. The subject matter of the invention thus allows one and the same coil to be used for a wide variety of voltages, depending on the circuit, so that the operational readiness of transformers with such windings is much greater than with an otherwise conventional design.

The series connection of the coils can be done by diversions outside the winding or within the same, as in coil 4 by the dashed line Line i is indicated, while the dashed line 2 the connection of the individual Indicates partial turns in the various coils. Even taps on somebody Point of the winding are possible in contrast to the known helical winding without that this disrupts the good current distribution. Between the strands or Wire groups can be arranged cooling channels, which in case of eventual Voltage difference at the same time contribute to the insulation. As a result of peculiarity The twist is characterized by a particularly high mechanical strength Strength. Their internal winding capacity, which is high in relation to the earth capacity makes them particularly sensitive to surge voltages.
