Novel GIL pipeline bus internal particle adsorption device

Abstract

The invention discloses a novel GIL pipeline bus internal particle adsorption device comprising a GIL shell, a supporting base and a dedicated compression bolt. The supporting base is provided with the GIL shell, an insulating supporting member and a particle adsorber. The insulating supporting member and the particle adsorber are arranged in the GIL shell. The insulating supporting member penetrates through the particle adsorber. The insulating supporting member and the insulating base are connected in a threaded way. An enclosed equipotential area is formed by the back surface of the particle adsorber and the supporting base. The top part of the supporting base is provided with a gasket. The top part of the gasket is provided with a tubular conductive rod which is internally provided with a conductive rod fixing backing plate. The dedicated compression bolt penetrates through the conductive rod fixing backing plate, the tubular conductive rod and the gasket to enter into the insulating supporting member. According to the novel GIL pipeline bus internal particle adsorption device, insulation of equipment does not form a threat so that the safety of people can be protected and disasters can be reduced.

Description

technical field [0001] The invention relates to a particle adsorption device, in particular to a novel particle adsorption device inside a bus bar of a GIL pipeline, which belongs to the field of power transmission pipelines. Background technique [0002] With the rapid development of my country's economy, the demand for electricity is increasing. Large-scale hydropower stations and nuclear power stations have been or started to be constructed. Due to the constraints of terrain and environmental conditions or safety requirements, these stations will use more GIL. When the GIL transmission pipeline is used for a relatively long transmission distance, the thermal expansion and contraction effect will cause the deformation of the conductive rod in the axial direction, so that the conductive rod slides between the two compression gaskets of the insulating support, and the conductive rod rubs against the gasket. Fine metal particles will be produced at the time. If the particles ...
