Abstract

The invention relates to a power transmission line pipeline and a gas insulation line. The power transmission line pipeline comprises three sub-pipelines in insulation connection in order, wherein each sub-pipeline comprises a metal shell and a composite material shell coated on the outside of the metal shell, and two ends of the power transmission line pipeline are grounded; furthermore, the gasinsulation line comprises a plurality of connected pipeline units; each pipeline unit comprises an A-phase pipeline, a B-phase pipeline and a C-phase pipeline; three groups of crossly interconnected electric loops containing A-phase sub-pipelines, B-phase sub-pipelines and C-phase sub-pipelines are formed among three-phase pipelines. The technical effect is as follows: three metal shells in different phases are interconnected and form the electric loops together with the ground, the induced electromotive force produced by the whole electric loop can be basically and mutually counteracted, theinduction current produced in the electric loop can be greatly reduced, the heating phenomenon of the metal shell can be greatly reduced, the power transmission loss is reduced, the safety running ofthe equipment is improved, and the economy of the power transmission system is improved.

Description

technical field [0001] The invention relates to the technical field of power transmission lines, in particular to a power transmission line pipeline and a gas insulated line. Background technique [0002] According to the requirements of special climate and geographical environment or the development needs of urban underground power transmission, a gas insulated line is produced, which is a high-voltage, high-current power transmission equipment that uses insulating gas insulation and coaxial arrangement of the shell and the conductor. Gas insulated lines have the characteristics of no insulation aging, low loss, good safety protection, and small footprint, and have advantages in large-capacity and long-distance power transmission. Since the gas insulated circuit is a pipe-enclosed structure, direct burial, outdoor erection and tunnel installation can usually be used. Therefore, the installation is very flexible for different natural environments. Compared with cables and ...
