Description

An inverted oil-immersed current transformer body support structure

technical field

The utility model relates to a body supporting structure of an inverted oil-immersed current transformer, which belongs to the technical field of transformer manufacturing.

Background technique

At present, the inside of the inverted oil-immersed current transformer mainly relies on the cushioned stay between the oil conservator and the body to conduct the transformer oil between the oil conservator and the porcelain suite. The weight of the entire body is pressed on the stay, and in order to ensure The fluidity of the transformer oil is good, and the contact surface between the stay and the body is small, so the insulating paper and the capacitive screen inside the body are easily squeezed, deformed, and partial discharge may occur, affecting product performance.

Utility model content

The purpose of this utility model is to provide an inverted oil-immersed current transformer body support structure, so that the oil circuit gap space between the inner wall of the oil storage tank and the body is increased, and the insulation and capacitance screen in the triangular area of the body are no longer affected. Extrusion has a simple structure and solves the above-mentioned problems in the background technology.

The technical scheme of the utility model is:

An inverted oil-immersed current transformer body support structure, including a base, a support flange, a reinforcing rib, an aluminum tube, a shielding cover and bolts, one end of the aluminum tube is welded to the shielding cover, and the other end of the aluminum tube is welded to the support The flanges are welded together, and multiple reinforcing ribs are welded between the supporting flange and the aluminum tube; the main insulation is wrapped outside the aluminum tube and the shield to form the body; the supporting flange at the bottom of the body is fixed on the base with bolts.

First, weld one end of the aluminum tube to the shielding cover, weld the other end of the aluminum tube to the supporting flange, and weld multiple reinforcing ribs between the supporting flange and the aluminum tube; then, outside the aluminum tube and the shielding cover Wrap the main insulation to form the body; then fix the supporting flange at the bottom of the body to the base with bolts.

The positive effect of the utility model is that the oil passage space between the porcelain sleeve, the body and the oil storage tank is enlarged, the insulation of the body is no longer squeezed, the connection between the body and the base is simple and firm, and the product quality is improved.

Fig. 1 is the embodiment schematic diagram of the present utility model;

In the figure: base 1, supporting flange 2, reinforcing rib 3, aluminum tube 4, shielding cover 5, bolt 6, main insulation 7.

detailed description

Below in conjunction with accompanying drawing, the utility model is described further by embodiment.

An inverted oil-immersed current transformer body support structure, including a base 1, a support flange 2, a reinforcing rib 3, an aluminum tube 4, a shielding cover 5 and bolts 6, and one end of the aluminum tube 4 is welded to the shielding cover 5 , the other end of the aluminum tube 4 is welded together with the supporting flange 2, and a plurality of reinforcing ribs 3 are welded between the supporting flange 2 and the aluminum tube 4; the main insulation 7 is bound outside the aluminum tube 4 and the shielding cover 5 to form a body ; Fix the support flange at the bottom of the body on the base 1 with bolts.

First weld one end of the aluminum tube 4 to the shielding cover 5, weld the other end of the aluminum tube 4 to the support flange 2, and weld a plurality of ribs 3 between the support flange 2 and the aluminum tube 4; then, Wrap the main insulation 7 outside the aluminum tube 4 and the shielding cover 5 to form a device body; then fix the supporting flange at the bottom of the device body on the base 1 with bolts.
