Transformer bushing and manufacturing method thereof

Abstract

The invention discloses a transformer bushing and a manufacturing method thereof. The transformer bushing comprises a base, a porcelain cap and a high-temperature-resistant pipe; threads are arranged on the outer side of the base, an insulating protective shell is arranged on the outer side of the threads, a sealing gasket is arranged above the insulating protective shell, and a first porcelain bushing is arranged above the sealing gasket. The invention has the beneficial effects that the structure is novel, operation is convenient and fast, heat insulation can be conducted on the interior of the bushing through the arrangement of the high-temperature-resistant pipe, firing cracks caused by too high temperature in the bushing are avoided, the use efficiency of the transformer bushing is improved, and the interior of the transformer bushing can be cooled through the arrangement of the cooling oil pipe; by arranging the insulating protective shell, moisture prevention can be carried out on the bottom of the transformer bushing, short-circuit burning loss caused by moisture between the transformer bushing and a transformer is avoided, and the use requirement of the transformer bushing is met.

Description

technical field [0001] The invention relates to the technical field of transformer bushings, in particular to a transformer bushing and a manufacturing method thereof. Background technique [0002] The transformer bushing is the main insulation device outside the transformer box. The lead-out wire of the transformer winding must pass through the insulating bushing to insulate between the lead-out wires and between the lead-out wire and the transformer shell, and at the same time play the role of fixing the lead-out wire. [0003] At present, most of the existing transformer bushings adopt a simple structure. Due to the long-term operation of the bushing, it is easy to cause the temperature in the bushing to be too high and cause burning. Secondly, due to the lack of sealing parts, it is easy to cause short-circuit burning between the transformer bushing and the transformer due to moisture, which cannot meet the needs of the transformer bushing.
