Three-phase oil-immersed power transformer

Abstract

The invention relates to a three-phase oil-immersed power transformer, which comprises a box body, sleeving devices and a placing device, a plurality of round holes are symmetrically distributed at the upper end of the box body front and back and are uniformly formed from left to right, the sleeving devices are mounted in the round holes, and the placing device is mounted at the lower end of the box body. The three-phase oil-immersed power transformer can solve the problems that when an existing three-phase oil-immersed power transformer is installed and used, corresponding adjustment cannot be carried out according to the length of a high-voltage wire outlet end and the length of a low-voltage wire outlet end, so that the wire outlet ends with different lengths cannot be protected, corresponding adjustment cannot be carried out according to the angles of the wire outlet ends, connection of the wire outlet ends is prone to being affected, the use flexibility of the transformer is reduced, the use occasions of the transformer are reduced, meanwhile, the transformer cannot be installed on a slope surface, a step position and an uneven surface position, the applicability of the transformer is reduced, horizontal adjustment cannot be conducted after installation, and the use of the transformer is affected.

Description

technical field [0001] The invention relates to the technical field of transformer use, in particular to a three-phase oil-immersed power transformer. Background technique [0002] The three-phase oil-immersed power transformer adopts a fully oil-filled sealed corrugated oil tank shell, which adapts to the expansion of oil with its own elasticity and is a permanently sealed oil tank. The core part of the three-phase oil-immersed power transformer is composed of closed iron core and Composed of windings set on iron core columns; three-phase oil-immersed power transformers also include oil tanks, oil conservator, bushings, respirators, explosion-proof pipes, radiators, tap changers, gas relays, thermometers and oil purifiers, Three-phase oil-immersed power transformers need to be installed and constructed, and adjusted and connected. [0003] At present, the existing three-phase oil-immersed power transformers usually have the following deficiencies when they are installed an...

AI Technical Summary

Problems solved by technology

[0005] The present invention can solve the problem that the existing three-phase oil-immersed power transformer cannot be adjusted according to the length of the high-voltage outlet and the low-voltage outlet when it is installed and used, so that the outlets of different lengths cannot be protected, and it cannot be adjusted according to the length of the outlet. The corresponding adjustment of the angle of the terminal will easily affect the connection of the outlet terminal, thereby reducing the flexibility of the transformer and reducing the use of the transformer. At the same time, it cannot be installed on slopes, steps and uneven surfaces, thereby reducing The applicability of the transformer, and, after installation, the level cannot be adjusted, which will affect the use of the transformer and other problems
