The invention relates to a transformer outgoing line device. The transformer outgoing line device comprises a tank cover of a transformer oil tank, an outgoing line hole for outgoing of a high-tension lead cable is formed in the high-tension side of the tank cover, an ascending flanged base is further arranged on the high-tension side of the tank cover, the outgoing line hole is covered by the ascending flanged base, a base hole is formed in the side wall of the ascending flanged base, an inner cone socket installed on the base hole in the horizontal direction is arranged in the ascending flanged base, a socket electrode on the inner cone socket is electrically connected with the high-tension lead cable, an inner cone insulating choke plug which is installed matched with the inner cone socket is arranged on the outer side wall of the ascending flanged base, and an inner cone pluggable terminal is inserted in the inner cone insulating choke plug. The transformer outgoing line device is reasonable in design and compact in structure, meanwhile, the boundary dimension of a transformer is reduced, and installation and transportation are facilitated; the performance requirements for full sealing, full insulation, dirt prevention and the like are met.
Description
technical field [0001] The invention relates to a transformer lead-out device, which belongs to the field of transformer manufacturing. Background technique [0002] Power cables are cables used to transmit or distribute high-power electric energy in power systems. They have the characteristics of high working voltage, large transmission capacity, and can be laid in various occasions. [0003] With the vigorous development of my country's electric power industry and petrochemical industry, the use of cross-linked power cables is becoming more and more extensive, and new requirements are put forward for the connection and installation of power transmission and distribution transformers: such as requiring transformers to be fully sealed and fully insulated , space-saving, anti-pollution, etc.; while the anti-wet flashover and pollution flashover performance of ordinary porcelain bottle bushings is not ideal, and the electrical contacts are exposed, which cannot meet the require...
