Abstract

The invention provides a fully-fabricated direct-current high-voltage insulation tubular busbar joint, and relates to the technical field of insulation tubular busbars. The fully-fabricated direct-current high-voltage insulation tubular busbar joint comprises a connecting base, wherein the right end of the connecting base is fixedly connected with the left end of a connecting terminal; the right end of the inner wall of the connecting base is fixedly connected with a threaded rod; the surface of the threaded rod is connected with a threaded pipe in a sleeving manner; the interior of the connecting base is connected with a fixed plate in the sleeving manner; a through hole is formed in the left side of the fixed plate; a cross rod is arranged inside the through hole in an inserted manner; and the right end of the cross rod is fixedly connected with the left end of the threaded pipe. According to the fully-fabricated direct-current high-voltage insulation tubular busbar joint, through the arrangement of the threaded rod, the threaded pipe, the fixed plate, the through hole and the cross rod, when the cross rod is stressed to rotate, the cross rod drives the threaded pipe to rotate, and the inner wall of the threaded pipe moves rightwards slowly along the threaded rod, so that the cross rod and the threaded rod are fixed together to play a connection role, the operation is simple,and the joint is convenient to dismount and mount.

Description

technical field [0001] The invention relates to the technical field of insulating tubular bus bars, in particular to a fully prefabricated DC high-voltage insulating tubular bus joint. Background technique [0002] Tubular insulated busbar is a transmission device that efficiently transmits high-voltage current. With the rapid and steady growth of the national economy, social power consumption has risen linearly, which has continuously increased the capacity of the main transformer of the substation. The rated voltage of the low-voltage outlet side of the main transformer The current also increases, and more and more tubular insulated busbars are used in the power sector. Compared with traditional rectangular busbars, tubular insulated busbars have good skin effect, large carrying capacity per unit section, good heat dissipation conditions, and allowable stress Large, large span, high mechanical strength, strong electrical insulation performance, high stability of the main i...
