摘要： The invention specifies a compact and cost-effective diode-split high-voltage transformer for high voltages of, in particular, above 20 kV, in which the high-voltage winding (W2 - W5) lies in chambers (8) of a coil former (9) underneath the primary winding (W1), and which contains means by which the electric field between the coil former (9) and the core is reduced in order to avoid corona effects. These means are, for example, a conductive coating of the surface (15) of the inner cavity (11) of the coil former (9), which coating preferably comprises colloidal graphite. The conductive coating may also be realized by a metallized plastic film which is wound between the core and the coil former (9). As an alternative, the cavity (11) between the core and the coil former (9) may be filled with a material whose relative permittivity epsilon r is distinctly greater than that of air. The use of a larger number of diodes is also possible as the means for reducing the electric field. The high-voltage winding (W2 - W5) is essentially covered completely by the primary winding (W1), with the result that the interference radiation produced in the high-voltage winding is virtually completely screened. Applications arise in particular for television sets and computer monitors.
摘要翻译：本发明规定了用于特别是高于20kV的高电压的紧凑且具有成本效益的二极管分压高压变压器，其中高压绕组（W2-W5）位于线圈架的室（8）中（9）在初级绕组（W1）下面，并且其包含减少线圈架（9）和铁芯之间的电场的装置，以避免电晕效应。这些装置例如是线圈架（9）的内腔（11）的表面（15）的导电涂层，该涂层优选包括胶体石墨。导电涂层也可以通过卷绕在芯体和线圈架（9）之间的金属化塑料膜来实现。作为替代，芯和线圈架（9）之间的空腔（11）可以填充相对介电常数εr明显大于空气的材料。使用更大数量的二极管也可以作为减小电场的手段。高压绕组（W2-W5）基本上被初级绕组（W1）覆盖，结果是在高压绕组中产生的干涉辐射几乎完全被屏蔽。应用尤其适用于电视机和电脑显示器。

摘要： A high-frequency slit transformer which can be manufactured at a low cost by automating the coil winding method and performing the impregnation step performed for preventing the disconnection of coils not by using any vacuum device, but under an atmospheric pressure. In the high-frequency slit transformer, a winding section (106) of a bobbin has a plurality of slits (150), and supporting sections (129) of an upper core (300) and a lower core (200) are respectively fixed to fixing sections at both ends of the bobbin. In addition, projecting sections (131) of cores (300 and 200) are opposed to each other with a prescribed gap in between in a through hole (104) of the bobbin, and the other projecting sections (132a and 132b) of the cores (300 and 200) are connected and fixed to each other on the outside of the winding section (106) of the bobbin. Furthermore, primary and secondary coils which are wound around the winding section (106) are alternately housed in the slits (150) on both sides of the projecting sections (131) on the basis of the gap formed of the sections (131).
