Abstract

Provided is a buried dry-type energy-saving transformer. The buried dry-type energy-saving transformer comprises a box, a transformer core installed in the box, a cover plate fixed on the upper portion of the box and internally-conical connectors arranged on the cover plate; each internally-conical connector comprises an internally-conical casing pipe cured in the box through colloid heating, a high-voltage cable connector copper base installed at the bottom of the internally-conical casing pipe, fixing bolts fixed to the high-voltage cable connector copper base, a high-voltage cable connector connected with a corresponding high-voltage lead and a corresponding low-voltage lead and a low-voltage cable connector connected with a corresponding low-voltage lead. The buried dry-type energy-saving transformer has the advantages that the structure is simple, operation is convenient, and overhigh or overheat protection on the temperature is achieved; the transformer adopts an amorphous alloy iron core, and therefore the no-load loss of the transformer is effectively reduced; the box is treated through an acid and alkali process, and therefore the corrosion resistance of the transformer is improved; the transformer saves energy, is environmentally friendly, reduces the cost, can be used in middle-voltage distribution systems of large bridges, expressways, long-distance tunnels and the like and is wide in application range.

Description

【Technical field】 [0001] The invention relates to the technical field of transformers, in particular to an underground dry-type energy-saving transformer. 【Background technique】 [0002] Small-capacity buried transformers are widely used for power distribution in large bridges, expressways, and long-distance tunnels. At present, there are 3 medium-voltage cable connectors and 3 medium-voltage fuses installed on the box cover of the buried transformer available for design and selection. They are independent, occupy a lot of space, and have many openings in the box cover. The existing medium-voltage cable connectors also mostly use general-purpose cable plugs, and their protection grades are lower than IP68. In addition, the existing buried transformers also lack energy-saving technology for heat resistance and corrosion resistance. Therefore, it is necessary to further improve energy saving and environmental protection for buried transformers. 【Content of invention】 [0...
