Abstract

The invention discloses an underground transformer. The underground transformer comprises a transformer core, a transformer winding, a transformer box and a voltage display meter; the transformer winding comprises a first winding and a second winding; a first supporting apparatus is arranged on the first winding; a second supporting apparatus is arranged on the second winding; the transformer core is arranged between the first supporting apparatus and the second supporting apparatus; multiple output ends are arranged on the left side of the transformer box; multiple output binding posts are arranged on the left side of the output end; an air cylinder is arranged above the output binding posts; a connecting apparatus is arranged below the air cylinder; and an input connecting end is arranged on the left side of the transformer box. By virtue of the underground transformer provided by the invention, voltage adjustability and quite convenient operation are realized; and meanwhile, by virtue of the setting of damping devices and elastic supporting columns, the mechanical performance of the transformer is improved.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to an underground transformer. Background technique [0002] With the development of urban modernization, more and more attention is paid to urban planning and urban appearance. Ground-mounted power equipment not only occupies the surface area, is difficult to coordinate with the city appearance, but is also vulnerable to unintentional or malicious damage from the outside, thus affecting the reliability of power supply. . Therefore, power equipment that can operate below the ground is the trend of urban network transformation in the future, which is clearly reflected in the large number of underground power equipment used in many European and American countries. [0003] There are two types of structure for buried transformers. One is the European type, which uses epoxy resin as the insulating material. The product is characterized by easy installation, directly digging the p...
