Abstract

The invention relates to a high voltage transformer for TV receiver, a primary winding P is wound by single strand wire layers P1 and P2 where one layer is placed flatly on another layer, besides a lining 5 made of medium is arranged between each two layers, single strand wires are adopted in place of traditional multi-strand wires, so that the cost of the primary winding is reduced by 7 times and can meet the requirements of coupling, copper loss and skin loss. The high voltage transformer is in particular applied in the TV receiver with row frequency enhanced to 32KHz.

Description

technical field

[0001] The invention relates to a high-voltage transformer, in particular to a high-voltage transformer in which single-strand wires can be used instead of multi-strand wires for the primary winding of a television receiver. Background technique

[0002] The invention relates to a high-voltage transformer of a television receiver. In transformers of this type, it is well known to use strands of wire to wind the primary winding. In order to keep the so-called skin loss low enough, the primary winding must use multi-strand wire, which is especially necessary for the relatively high 32kHz horizontal frequency. However, primary windings made with stranded wire are seven times more expensive than single-stranded wire and have disadvantages in winding operations, soldering, and fixing to transformer terminals. Contents of the invention

[0003] The purpose of the present invention is to design a high-voltage transformer for television receivers, so that the pri...
