Expansion joint with displacement real-time monitoring function and large displacement compensation

Abstract

The invention discloses an expansion joint with a displacement real-time monitoring function and large displacement compensation. The expansion joint comprises a corrugated pipe assembly, wherein an online monitoring assembly is assembled on the outer side of the corrugated pipe assembly; two proportional connecting rod assemblies are symmetrically assembled on the periphery of the corrugated pipeassembly; a plurality of screw rod assemblies are assembled on the periphery of the corrugated pipe assembly; and the screw rod assemblies are distributed in a circumferential mode. According to theexpansion joint, the requirements of large displacement compensation and high fatigue life can be met, meanwhile, the possibility of product instability is greatly reduced, meanwhile, the compensationdisplacement of two corrugated pipes can be uniformly distributed and implemented, screw threads can be effectively protected, the thread abrasion is reduced, and the real-time online monitoring of the displacement amount of a product, namely axial displacement, transverse displacement and angular displacement, can be effectively realized.

Description

technical field [0001] The invention relates to the technical field of expansion joints for power transmission and transformation, and specifically relates to an expansion joint with real-time displacement monitoring functions and large displacement compensation. Background technique [0002] High-voltage gas-insulated transmission lines are products between power equipment manufacturing and power cable industry. Compared with high-voltage overhead and cable lines, it has large transmission capacity, less heat and electric energy loss, good energy-saving effect, no electromagnetic interference, low radiation, good protection performance, less maintenance, extremely low failure rate, and ability to resist ice, snow, earthquakes and other disasters Strong, excellent fire resistance, high safety and reliability, long service life (up to half a century), transmission corridor and small footprint; the arrangement of shell expansion joints is particularly important in high-voltage...
