The invention relates to an underground transformer high-voltage cable connection and high-voltage fuse protection integrated sealing base. The integrated sealing base consists of a high-voltage cableconnection insulation base and a high-voltage fuse protection sealing base, wherein the high-voltage cable connection insulation base consists of a sealing cover, a pressure cover, an insulation baseand a metal insert, the high-voltage fuse protection sealing base consists of an insulation chamber with one open end and a metal insert, the high-voltage cable connection insulation base is fixed through a bolt and extends to the insulation chamber of the high-voltage fuse protection sealing base at the open end, the high-voltage fuse protection sealing base is fixed on a fuel tank cover througha cover bolt, the bottom is connected with a coil in a casing, the high-voltage cable connection base is fixed on a seat surface by a bolt arranged on the high-voltage fuse protection sealing base and is connected with a fuse body in the high-voltage fuse protection sealing base through the metal insert on one side thereof and a fuse body screw, a high-voltage cable is fixed with fixing screws inthe insulation chamber through cable through holes at two sides to achieve ring or terminal connection, and all the points are fully sealed through a two-way sealing ring and a sealing cover. The integrated sealing base is advantaged in that safe operation guarantee of underground transformers in the harsh environment in the prior art is greatly improved, moreover, IP68protection requirements satisfying GB / T10544 requirements are further satisfied.
Description
[0001] Technical field: [0002] The invention relates to the field of electricity, in particular to an underground transformer, in particular to a sealed base integrated with high-voltage cable connection and high-voltage fuse protection for an underground transformer. [0003] Background technique: [0004] In the prior art, the underground transformer is equipped with high-voltage cable connection mode and fuse protection. Regardless of whether it is European or American, the components are installed separately. It is beneficial to the miniaturization of underground transformers and the protection of faulty nodes is cumbersome. [0005] Invention content: [0006] The object of the present invention is to provide an integrated sealing base for high-voltage cable connection and high-voltage fuse protection for underground transformers. The technical problem of the integrated operation of connection and high-voltage fuse protection is simple, economical, applicable, reliable...
