Novel horizontal dry-type power transformer

Abstract

The invention relates to a novel horizontal dry-type power transformer, comprising a horizontal iron core and a shell, wherein the horizontal iron core is externally provided with a low-voltage coil,a main insulating air channel between a high-voltage coil and the low-voltage coil, and the high-voltage coil; one side of the horizontal iron core is provided with a high-voltage lead, a high-voltagelead screw, a high-voltage lead insulator, a low-voltage side insulator, a low-voltage side zero line row and a low-voltage side outgoing line row; the other side of the horizontal iron core is provided with a fan for cooling the device body and a guide baffle; and the upper and lower end surfaces of the horizontal iron core are provided with horizontal iron core clamps. According to the horizontal dry-type transformer disclosed by the invention, the device body is horizontally installed, occupies a small space, and can be conveniently installed in a mobile power supply station, and moreover,the horizontal dry-type transformer is particularly suitable for being used as a transformer of a mobile power supply due to the characteristics of no flammability and explosion, a special ventilation and heat dissipation structure of the horizontal dry-type transformer is beneficial to the dissipation of heat generated during the operation of the transformer, and the efficiency of forced heat dissipation can greatly enhance the overload resistance of the transformer.

Description

technical field [0001] The invention relates to the technical field of power transformers, in particular to a novel horizontal dry-type power transformer. Background technique [0002] Dry-type transformers, due to the characteristics of their insulating materials, such as encapsulated transformers are casted with epoxy resin in a vacuum state; non-encapsulated transformers are made of H-class insulating materials such as DuPont paper, which are vacuum-impregnated and formed, and have short-circuit resistance Strong, good heat dissipation performance, no oil leakage, no pollution to the environment, no explosion and combustion, so it is widely used in some places with special requirements. With the rapid development of economic construction, there will be more and more construction projects that need to provide mobile power supply, and mobile power supply equipment is limited by volume and installation methods, which cannot well meet the requirements of mobile power supply o...
