- A Study on Particle Trap
In GIS(Gas Insulated Switchgear) and GIL(Gas Insulated Transmission Line), SF_6 gas is used as an insulating medium. If the metallic particles enter GIS or GIL, the particles are electrified and lifted in SF_6 gas space by the electric field and moreover move randomly and attach the surface of an insulator. In the worst case, the flashover will happen on the surface of the insulator. So many types of the particle trap which trap the harmful particles have been mounted in GIS and GIL. We designed two types of the particle trap and calculated the electric field in it and conducted the optimum shape and size.
