Oil-immersed transformer

Abstract

The invention discloses an oil-immersed transformer, which comprises a tank body and a damping base, wherein a tank cover is arranged at the upper part of the tank body and is provided with a high-voltage binding post and a low-voltage binding post; the low-voltage binding post comprises a connector lug, a conducting rod and a porcelain cover; the porcelain cover sleeves the lower part of the conducting rod and the connector lug sleeves the upper part; an oil tank is arranged in the tank body; a high-voltage coil and a low-voltage coil are arranged in the oil tank; a stirring device is arranged at one of two sides of the inner wall of the oil tank through one fixed part; an oil-level display is arranged on the outer wall of the tank body; the damping base is arranged at the bottom of the tank body and comprises three damping strips which are enclosed into a triangle; the damping strips are C-shaped; and a damping spring is arranged between an upper panel and a lower panel. The oil-immersed transformer is simple in structure, reliable in installation, firm in connection and high in voltage resistance strength, raw materials are saved and vibration when the transformer works can be effectively reduced, so that noise is reduced, the cycling speed of oil in the oil tank can be effectively improved and the heat dissipation performance of equipment is improved.

Description

[0001] This application is the application number: 2014104787340, the application date: September 18, 2014, and the title of the invention: a divisional application for an oil-immersed transformer. technical field [0002] The invention relates to a transformer, in particular to an oil-immersed transformer. Background technique [0003] The oil-immersed transformer will continue to increase the oil temperature during the working process. The oil temperature generally passes through the circulation between the tank wall and the inside of the tank to reduce the oil temperature. However, the oil circulation process between the inner wall and the inside of the tank is slow, and the convection strength of the oil is low. , which is not conducive to reducing the oil temperature of the oil-immersed transformer, and it is easy to cause the oil temperature inside the oil-immersed transformer to rise continuously under high-intensity work, which has potential safety hazards; the transf...

[0003] The oil-immersed transformer will continue to increase the oil temperature during the working process. The oil temperature generally passes through the circulation between the tank wall and the inside of the tank to reduce the oil temperature. However, the oil circulation process between the inner wall and the inside of the tank is slow, and the convection strength of the oil is low. , which is not conducive to reducing the oil temperature of the oil-immersed transformer, and it is easy to cause the oil temperature inside the oil-immersed transformer to rise continuously under high-intensity work, which has potential safety hazards; the transformer will generate noise pollution due to its own vibration during the working process, which will affect the surrounding environment. People's work and rest; the traditional high-voltage coil wire has low withstand voltage strength, narrow application temperature range, low tensile strength of the insulating layer, which is not conducive to wrapping, and the thickness of the insulating layer is large. When winding the coil, the central wire consumables are increased and the production is increased Cost; the length of the exposed part of the compression nut and the conductive rod of the traditional low-voltage terminal is large, the length of the conductive rod is long, and the fastening bolt is arranged on the side of the conductive rod, which increases the amount of materials and high cost.
