A novel particle trap in compressed air insulated transmission line

Some tiny metallic particles generated due to the manufacturing process as well as the mechanical operation in the compressed gas-insulated transmission line, which may induce breakdown should be cleared from the volume of the apparatus not only at the very beginning of the manufacturing period but also during the operation cycle. In the operation period the metal particles are trapped in the electromagnetic trap so it cannot give rise to the breakdown in the compressed air insulated transmission lines. In this paper several forms of particle trap that are used for clearing and deactivating particles, are briefly described and a new form of particle trap that draw the advantages of the current methods to deactivate the particles contaminating is proposed, furthermore the structure dimension of the particle trap is also calculated.
