Abstract

The invention relates to a connection method of a transformer outgoing line and a bus and a winding structure, and belongs to the technical field of transformer manufacturing equipment. According to the technical scheme, an outer side tube shaft (3) is arranged in a tube shaft housing (4); a metal tube shaft (1) is arranged in the outer side tube shaft (3); one end of the metal tube shaft (1) is fixed on the tube shaft housing (4); the metal tube shaft (1) and the outer side tube shaft (3) are concentrically arranged; volute spiral springs (2) are arranged at two ends of the metal tube shaft (1) and the outer side tube shaft (3) respectively; one end of each volute spiral spring (2) is fixed at the outer side of the metal tube shaft (1) and the other end of each volute spiral spring (2) is fixed to the inner wall of the outer side tube shaft (3); and a connection cable (5) penetrates inside from one end of the metal tube shaft (1) and is wound on the outer side tube shaft (3). The connection method has the beneficial effects that the damage to a sleeve due to pulling of the connection cable between the transformer outgoing line and the bus is completely eradicated; and normal operation of a transformer is ensured.

Description

technical field [0001] The invention relates to a connection method between a transformer outgoing line and a bus bar and a winding structure, and belongs to the technical field of transformer manufacturing equipment. Background technique [0002] The power transformer is one of the most complex and core electrical equipment in the power system. With the increase of voltage level and variable capacity, the vibration and earthquake of the transformer itself have become important factors affecting the normal operation of the transformer. A large number of researches on transformer vibration monitoring and control have been carried out at home and abroad. [0003] Due to the transformer's own vibration or earthquake, the connecting cable between the transformer outlet and the busbar will be pulled, resulting in damage to the transformer bushing and affecting the normal operation of the transformer. Therefore, improving the anti-seismic capability of transformers is an importan...
