遮蔽電極に関する。[Detailed Description of the Invention] [Industrial Application Field] This invention consists of forming a conductive tube with a circular cross section into a closed ring, wrapping it with paper, and allowing the air inside the tube to reach the insulating oil of the transformer. The present invention relates to a shielding electrode of a tap changer for an on-load tap change transformer, which has a structure that prevents contamination.

難点は重さが重いことにある。
Shielding electrodes of this type are usually designed as shielding rings made of steel tubes. This can be done, for example, by welding pressed split shells together to form a shielding ring. In that case, the weld seam must then be leveled to provide a smooth surface. It is also necessary that the weld seam be hermetically sealed so that exchange of air and oil in the shielding ring does not occur within the shielding ring. In addition to the manufacturing process, which is itself expensive, a further leakage test is therefore added. However, this method is even more expensive if the shielding ring deviates from a circle and has, for example, an oval or figure-eight shape, as in the case of shielding rings for potential control in on-load tap changers. It takes. This type of shielding ring must be assembled from individual arcuate pieces and straight tubing.
Another disadvantage of shielding rings made from steel or tubing is their heavy weight.

The effects obtained by this invention are particularly as follows. The above-mentioned shielding electrode can be manufactured easily, for example by using a corrugated tube 5, which is well known in the art of ventilation systems and air conditioners. This shielding electrode has
It has sufficient dimensional stability even if it is very light in weight. There is no exchange of air and oil. Also,
It is extremely easy to manufacture shapes other than circular, and this flexible metal tube 5 can be cut to a desired length.
It is also easy to match the desired contour. It is bent into a circular tube shape and connected by spring plates inserted into both ends of the tube body 5. An aluminum foil tape 6 is wrapped around the joint. A support/connection member 4 is used in the area that will be in the shadow of the electric field. Next, the multi-component plastic foam, which is inserted through a suitable opening in the tube 5, is foamed, hardened and then tempered in a mold to obtain good shape stability. Finally, wrap paper around this shield electrode in the usual way. Also, before integrating the ends,
The tube can also be filled with a filler, integrated, and then foamed.
