Inverted oil-immersed current transformer body supporting structure and manufacturing method thereof

Abstract

The invention relates to an inverted oil-immersed current transformer body supporting structure and a manufacturing method thereof, belonging to the technical field of transformer manufacturing. The supporting structure comprises a base (1), a supporting flange (2), reinforcing ribs (3), an aluminum tube (4), a shield (5) and bolts (6), wherein one end of the aluminum tube (4) is welded together with the shield (5) and the other end of the aluminum tube (4) is welded together with the supporting flange (2); a plurality of reinforcing ribs (3) are welded between the supporting flange (2) and the aluminum tube (4); the aluminum tube (4) and the shield (5) are externally bound by a main insulator (7) to form a transformer body; and the supporting flange at the bottom of the transformer body is fixed on the base (1) by the bolts. The supporting structure and the manufacturing method have the positive effects that the oil passage space among a porcelain sleeve, the transformer body and an oil conservator is enlarged, so that the insulator of the transformer body is no longer extruded; and the transformer body and the base are connected simply and firmly, thus improving the product quality.

Description

technical field [0001] The invention relates to an inverted oil-immersed current transformer body support structure and a manufacturing method thereof, belonging to the technical field of transformer manufacturing. Background technique [0002] 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. Contents of the invention [0003] The purpose of the present invention is to provide an inverted oil-immersed current transformer body support structure and its ...
