Definitions
- the invention relates to a high-voltage winding from disc coils for Transformers and chokes of high voltages, at least at High voltage input of the winding in some disks the conductors together are nested.
- the lightning voltage stress is reduced in the input area of the windings also with lightning voltage tests Full wave increases, so that additional insulation of the conductor does not necessarily lead to one Increase the lightning voltage resistance.
- the area of application is thus more like this Highly producible windings only with transformers and choke coils possible up to certain series voltages.
- GB-PS 1543996 is a high-voltage winding consisting of disc coils known with nested coiled discs at the high voltage input, at which the Continuously interconnected discs at least existing winding part a nested double pane is arranged upstream.
- the object of the invention is a conductor arrangement at the high voltage input of windings with axially wound disks that are continuous are linked together to find the lightning voltage stresses between the panes in tests with the lightning voltage wave cut off same size as for tests with solid shaft and at the same time the Lightning voltage wave are roughly the same size as in tests with full wave and at the same time reduces the level of lightning voltage stresses overall will.
- this is achieved by the high voltage input from the start of the spatial winding in the second disc of the first and thus the conductor-nested double disc lies and the wound Conductor in the second and third from the spatial winding start Disc the same sense of rotation and the wound conductor of this Disks immediately axially adjacent disks one and four have the opposite sense of rotation.
- the arrangement of at least one according to the invention conductor-nested double pane at the high voltage input of the Winding and the arrangement of the high voltage input in the second discs of the first double disc and the same sense of rotation the wound conductor in the second from the spatial winding start and third disc and the opposite direction of rotation of the wound Head of the axially immediately adjacent to these two disks Discs one and four of the winding is achieved at Lightning voltage tests of the winding with the shaft cut off Stresses between the input washers of the Winding in the same percentage size or smaller than for Tests with solid shaft and also the stresses between the input discs of the winding both in tests with full and also cut off lightning voltage wave can be significantly reduced.
- the Disc coil windings of large series voltages to reach a stepped longitudinal capacitance nested in different ways Discs at the winding entrance of approx. 1/3 of the total number of discs Winding can be reduced to a minimum of two discs, making the Labor cost for producing a winding is significantly reduced.
- the winding consists of at least two parallel, in the disks radially stacked conductors, so the longitudinal capacity in the if necessary, nested input disks of the winding a partial conductor nesting of the parallel connected conductors can be achieved.
- the high voltage input takes place in the second disc I-2 Turn 1 of the first double disk I.
- the passage in this double disk I happens in the manner shown up to the turn 40, whereupon the Transition into the first disc II-3 of the second double disc II takes place Seen from the start of the spatial winding into the third disc.
- the Pass in this double disc II follows the path shown up to Turn 80, from which the transition to turn 81 in the normal continuously wound double-disc coils III-V of the rest of the winding is shown.
