Problems solved by technology

[0003] Most of the traditional transformer bushings are fixed and compressed outside the box cover with bolts. This installation method has two disadvantages: first, the processing procedure is complicated, and the metal presser bolts reduce the effective insulation distance, resulting in Second, the external bolts will wear the protective anti-rust paint during the installation process. After being exposed to the sun and rain, it will inevitably cause rust spots to corrode the oil tank, which will cause great hidden dangers to safety and affect the life of the transformer.

Abstract

The invention discloses an internal pulling type insulating sleeve for an outdoor transformer, which comprises a porcelain sleeve body and an internal pulling fixing assembly, wherein the porcelain sleeve body comprises an umbrella skirt part, a base and a tail part extending into the transformer from top to bottom, the internal pullingfixing assembly is detachably connected to the tail part, after the tail part is inserted into the transformer, the porcelain sleeve body can be clamped and fixed on a shell of a transformer through the internal pullingfixing assembly, an external sealing ring is clamped between the base and the outer wall of the shell of the transformer after the porcelain sleeve body is clamped and fixed, and an embedded ring is embedded in the tail of the porcelain sleeve body and is connected with a sleeve through a thread, the porcelain sleeve base and the abutting ring are tightly attached to the outer side wall and the inner side wall of a transformer box cover respectively, and then the porcelain sleeve body is fixed. The internal pulling type insulating sleeve for the outdoor transformer has the effect that the sleeve only needs to be fixed through a metal piece inside the transformer, so that the metal piece is prevented from being exposed in the air to be corroded.

Description

technical field [0001] The invention relates to the technical field of power equipment, in particular to an inner-pull insulating bushing for an outdoor transformer. 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. Due to different voltage levels, insulating bushings are available in the form of pure porcelain bushings, oil-filled bushings and capacitor bushings. [0003] Most of the traditional transformer bushings are fixed and compressed outside the box cover with bolts. This installation method has two disadvantages: first, the processing procedure is complicated, and the metal presser bolts reduce the effective insulation distance, resulting in Second, the external...
