Description

technical field [0001] The invention relates to a method and a device for optimizing the installation position of a DC GIL particle trap, and belongs to the technical field of GIL of high-voltage transmission lines in power systems. Background technique [0002] Gas-insulated metal-enclosed transmission line (gas-insulated metal-enclosed transmission line, GIL) has the advantages of large transmission capacity, small footprint, and low transmission loss. It is the first choice to replace cables and overhead lines in many occasions. However, during the production, assembly and operation of GIL, the generation of metal particles is unavoidable, such as: metal shavings remaining due to poor internal cleaning during the production process, debris generated by extrusion friction during transportation, contact during operation, etc. Mechanical friction caused by plug-in connectors, and metal particles generated by discharge ablation. In the DC GIL cavity, the charged metal partic...
