Abstract

The present invention provides a prefabricated high-voltage fully insulated tubular bus intermediate joint conductive shielding pipe device, which includes a main pipe, a mounting hole is provided at the center of the main pipe, a shielding pipe is provided at the mounting hole, and a shielding pipe is provided at the center of the shielding pipe. Through hole, the main tube is used in conjunction with the shielding tube, the structure is simple, the design is reasonable, the clamping effect is better, time-saving, labor-saving, easy to clamp, the effect of force is better, it is not easy to break, prolong its service life, and is safe High performance, strong protection level, while the thickness of the main tube is 6-8mm, the thickness of the shielding tube is 3-4mm, the height h2 of the shielding tube is one-third of the height of the main tube h1, without affecting the overall strength Under the circumstances, the overall production cost is effectively reduced, the aesthetics is good, the production is convenient, and it can better meet the needs of producers.

Description

technical field [0001] The invention relates to the technical field of tubular busbars, in particular to a prefabricated high-voltage fully insulated tubular busbar intermediate joint conductive shielding tube device. Background technique [0002] Tubular busbar is one of the key equipment materials in the power transmission and transformation system, and plays a vital role in the safe and reliable operation of the power transmission and transformation system and power equipment. The conductive shielding tube device of the high-voltage fully insulated tubular bus intermediate joint is an indispensable part of the tubular bus joint. However, the existing conductive shielding pipe device for the intermediate joint of high-voltage fully insulated tubular busbar is a cylindrical structure, which is not conducive to clamping, low tightness, low protection level, and potential safety hazards. At the same time, the production cost is high and the production steps are cumbersome. c...
