Description

Technical Field

[0001] The utility model belongs to the technical field of transformer bushings, and in particular relates to an installation and positioning mechanism for transformer bushings. Background Art

[0002] The transformer bushing is the main insulating device outside the transformer box. The lead wire of the transformer winding must pass through the insulating bushing to insulate the lead wires and the lead wires from the transformer casing. At the same time, it plays the role of fixing the lead wires. Due to different voltage levels, the insulating bushing has pure porcelain bushings, oil-filled bushings and capacitor bushings. Pure porcelain bushings are mostly used in 10kV and below transformers. It is a conductive copper rod inserted in the porcelain bushing, and the inside of the porcelain bushing is air-insulated. Oil-filled bushings are mostly used in 35kV transformers.
