【考案の詳細な説明】 この考案は、その表面を何段かに分けた絶縁物で覆うこ

に関するものである。
[Detailed description of the invention] This invention relates to the structure of an oil-submerged shield electrode whose dielectric strength is improved by covering its surface with an insulating material divided into several stages.

In a conventional oil-submerged shield electrode, as shown in FIGS. 1 to 3, the surface of an electrode conductor 1 is covered with a taping layer 2 made of crepe paper to maintain insulation.

However, this type of electrode must have a potential gradient on its surface that can withstand oil insulation, so as the voltage used increases and the potential gradient on the electrode surface increases, the shape of the electrode conductor 1 must be made larger. Therefore, the potential gradient must be lowered or the distance of insulation in oil must be made larger than necessary, which has the disadvantage of increasing the external size of the transformer itself.

This idea was developed to eliminate the above-mentioned drawbacks of the conventional method, and by alternately covering the electrode conductor surface with a taping layer made of crepe paper and a corrugated presspod layer, the dielectric strength was improved. The object of the present invention is to provide an oil-submerged shield electrode that can be improved and the external shape of the transformer itself can be made more compact.

In the oil-submerged shield electrode according to an embodiment of the invention configured as described above, the presspod layer 3 is placed between the taping layers 2 serving as an insulating barrier to maintain appropriate spacing, thereby making it possible to finely divide the oil gap. The taping layer 2, which becomes an insulating barrier depending on the magnitude of the potential gradient, can create a barrier and strengthen the dielectric strength more effectively.
By increasing or decreasing the number of layers, the insulation can be strengthened to suit each usage condition without changing the size of the electrode conductor 1.
