Conveniently mounted transformer bushing

Abstract

The invention discloses a conveniently mounted transformer bushing. The conveniently mounted transformer bushing comprises a transformer bushing body, wherein an external bushing connector is arrangedat one end of the transformer bushing body; one end of the external bushing connector is fixed to one end of the transformer bushing body and embedded into the transformer bushing body; a connectingguide plate is arranged inside the transformer bushing body; one end of the connecting guide plate is connected to one end of the external bushing connector; insulated heat-dissipating porcelain cladsare arranged on the outer surface of the transformer bushing body; the insulated heat-dissipating porcelain clads and the transformer bushing body form an integral structure; heat-dissipating holes are formed in the surfaces of the insulated heat-dissipating porcelain clads; through the use of a bushing fixing pad plate and a pad plate limiting rod, the bushing fixing pad plate is placed on the surface of the bushing through the pad plate limiting rod, so that convenience in mounting the bushing fixing pad plate is improved, the time for mounting the bushing fixing pad plate is shortened, anda technical requirement for fixing the bushing is reduced; through the use of a bushing fixing screw cap, the bushing is fixed to a transformer through the bushing fixing pad plate and the bushing fixing screw cap.

Description

technical field [0001] The invention belongs to the technical field of transformer equipment, and in particular relates to a transformer bushing which is easy to install. 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. Pure porcelain bushings are mostly used in transformers of 10kV and below. It is a conductive copper rod inserted in the porcelain bushing, and the inside of the porcelain bushing is air-insulated. The oil-filled bushing is mostly used in 35kV transformers. It is filled with oil in the porcelain bushing, a...

Problems solved by technology

[0003] The purpose of the present invention is to provide a transformer bushing that is easy to install, so as to solve the problem that in the process of using the existing transformer bushing proposed in the above-mentioned background technology, the bushing is fixed on the transformer in a complicated installation method, which makes the installation of the transformer bushing difficult. With certain technical requirements, it takes a certain amount of time to install the transformer bushing. At the same time, the surface of the bushing is small. When the external temperature of the bushing is too high, the temperature cannot be dissipated in time. The increase in temperature increases the resistance of the conductive copper rod and makes the bushing The problem of tube temperature increase
