Embodiment Construction

[0012] figure 1 The main conductor of the high voltage coil for capacitance control is shown, which consists of two twisted wires 1 and 2 . Each twisted wire has a plurality of rectangular partial conductors 5 formed in stacks 3 , 4 arranged two by two next to each other. During the production of the twisted wires 1 and 2 , the uppermost and the lowermost conductor 5 are switched from the adjacent stack 3 and 4 into the other stack 4 and 3 , wherein the conductors 5 are each preferably offset by half a step. Here, a constant overall height is achieved with an odd number of twisted wires.

[0013] Each twisted wire 1 and 2 has an insulating sheath 1a and 2a, which are preferably covered by paper.

[0014] The two twisted wires 1 and 2 forming the main conductor are wrapped by a shell 6 made of crepe paper. As the crepe paper, slightly creped and calendered insulating paper is used for strength reasons.

[0015] Arranged between the twisted wires 1 and 2 are a plurality of c...

Abstract

In a main conductor for a capacitively controlled high-voltage winding composed of pancake coils for transformers, in which the main conductor for the load current is realized as a twisted conductor,and in which a control conductor is provided which is spatially arranged inside the twisted conductor and is electrically separated from the twisted conductor, the main conductor consists of two twisted conductors ( 1, 2 ) that are electrically separated from each other. The control conductor consists of several flat copper conductors ( 7 ) covered by an insulating sheath ( 7 a), and the copper conductors ( 7 ) are fastened to one of the twisted conductors ( 1, 2 ).

Description

technical field [0001] The invention relates to a main conductor for a capacitance-controlled high-voltage coil and a method for producing the main conductor for a capacitance-controlled high-voltage coil. Background technique [0002] DE19926540C1 discloses a high-voltage coil in which the coil winding is produced from so-called twisted wire. Additional losses due to stray fields can be reduced by using twisted wires. Furthermore, the available winding space is better utilized due to the increased fill factor. [0003] In each case, the manufacture of coils wound into each other requires welding, which can only be achieved with difficulty or not at all with twisted wire. In order to avoid welding, therefore, in the case of twisted wires, a continuously wound double-coil circuit is required, wherein the capacitive control takes place via special control lines, the welding of which is easily and economically possible. [0004] In DE19926540C1, the control line is located s...
