Embodiment

[0034] combine figure 1 with figure 2 , a combined transformer low-voltage bushing in this embodiment includes a conductive rod 1, a porcelain sleeve 3, a first sealing ring 2, a second sealing ring 4, a base 6 and a first nut 8, and one end of the conductive rod 1 is integrally formed with The round table 102 and the terminal, the terminal is located above the round table 102, without welding marks, avoiding local overheating due to poor welding, affecting the conduction of the conductive rod 1; the shape of the terminal is flat, and the terminal is provided with a wire The hole 101 can be easily connected with the wire, and the contact is good. The bottom of the round platform 102 is sequentially set with the first sealing ring 2, the porcelain sleeve 3, the second sealing ring 4 and the base 6. The radial dimension of the round platform 102 is larger than the radial dimension of the first sealing ring 2, preventing the first sealing ring 2 from Long-term direct exposure...

Abstract

The invention discloses a combined low-voltage bushing of a transformer, and belongs to the field of transformer bushings. The combined low-voltage busing of the transformer comprises a conductive rod, a porcelain bushing, a first sealing ring, a second sealing ring, a base and a first nut. A circular truncated cone and a connector lug are integrally formed at one end of the conductive rod. The connector lug is positioned above the circular truncated cone, and the first sealing ring, the porcelain bushing, the second sealing ring and the base are sequentially sleeved below the circular truncated cone. The other end of the conductive rod is provided with an external thread. The first nut is matched with the external thread to compress the base. Production cost of the low-voltage busing of the transformer is reduced, assembly technique is simplified, studs are not required to be welded on a transformer tank wall, incapability of mounting due to inaccurate welding positions is avoided, and good sealing effect is achieved.

Description

technical field [0001] The invention relates to a transformer bushing, in particular to a combined transformer low-voltage bushing. Background technique [0002] With the rapid development of my country's electric power industry, the use of transformers has increased sharply, and the requirements for transformers are higher. During the working process of the transformer, the transformer bushing is one of the key components that affect the performance of the transformer's power transmission and transformation. At present, during the installation and operation of the transformer, almost all the transformer bushings are fixed on the box cover of the transformer by the clamp-to-clamp installation method, and there is no overall installation. Not only need to manufacture or purchase a special clamp angle, The manufacturing cost of the transformer is increased, and the fixing of the transformer bushing is not firm enough, and the installation and replacement of clips are not very...
