A gil device and particulate trap

Abstract

The invention relates to a GIL device and a particle trap. It includes a cylinder, and a particle catcher is arranged in the cylinder. The surface of the particle catcher on the side close to the central conductor in the cylinder is an insulating surface when in use. In the axial direction of the cylinder, the cylinder has at least one The side and the inner wall are conductive wall sections of the conductive wall, and there is a space between the particle trap and the inner wall of the cylinder to form a shielding area for collecting particles. In the GIL pipeline of the present invention, the part adjacent to the particle catcher on the inner wall of the cylinder is the conductive section of the wall, so that the metal particles jump along the axial and radial directions of the cylinder under the action of the electric field force, and when the particles move to the conductive section of the wall The received electric field force is larger, and the particles move faster. The surface on one side of the particle catcher is an insulating surface, and the metal particles in contact with the particle catcher will not be charged again, so that the metal particles can be captured by the particle catcher.

Description

technical field [0001] The invention relates to a GIL device and a particle trap. Background technique [0002] With the rapid development of my country's economy, the demand for electric power is increasing. Due to the limitation of terrain environment conditions or safety requirements, gas insulated transmission lines (GIL) are used more and more. The GIL includes a metal cylinder filled with an insulating gas inside, a conductor that conducts electricity and flows inside the cylinder, and an insulator that insulates and supports the conductor. [0003] Metal particles will inevitably be produced during the production, transportation and operation of GIL. Due to the action of gravity, these metal particles will be distributed in the bottom of the cylinder. When the equipment is powered on, these metal particles will overcome gravity under the action of electric field force And move along a certain trajectory, if these particles are not captured, the particles will cause a...
