Abstract: An electrically insulating conducting system which includes a cylindrical outer electrode inside of which is disposed another electrode. These electrodes may be energized. An electrically conducting tubular barrier member is disposed around the inner electrode but inside of the outer electrode. An electrically conducting particle trap is disposed close to the barrier. The outer electrode is utilized to enclose sulfur hexafluoride insulating fluid which acts as an insulating means for the electrical system. Some particles which may float in the sulfur hexafluoride gas become trapped between the electrically conducting barrier and the proximate electrically conducting particle trap because the electrically conducting particle trap distorts the electric field which exists between the hollow outer electrode and the innermost electrode when a potential difference exists therebetween. Consequently, any particle which somehow enters the region associated with the barrier and the particle trap has a high probability of becoming trapped in that region.

Abstract: This invention relates to compressed-gas-insulated systems. An adherent or sticky coating is provided on selected surface areas inside compressed-gas-insulated systems to trap, or to captivate conducting and non-conducting particles, which if allowed to remain free can promote breakdown metallic parts or electrodes maintained at different potentials, or tracking and flashover along insulating surfaces. Preferably, a coating is provided which is initially hard or solid with adequate mechanical strength so that the system components can be easily handled by workmen during manufacturing and assembly without difficulty, and not at this stage capture unwanted particles. At a later time, following assembly operations, the surface layer of said coating is rendered adherent, or tacky to trap or to captivate conducting and non-conducting particles. During this stage mechanical means such as vibrations and/or gas flow and/or electric fields may be used to transport unwanted particles to the tacky or captivating areas. Following such captivation, the adherent, or sticky coating may be rendered hard again to trap the unwanted particles permanently. Alternatively, if desired, the coating may be rendered tacky, or captivating again during the life of the equipment to trap unwanted particles generated within or introduced into the system, thus performing a repair or reconditioning of the system. Another alternative is to maintain the coating sticky or tacky during the operating life of the electrical equipment and rendering the surface hard only during repair or maintenance operations when the system is opened and thus subject to handling and thereby large amounts of unwanted particles.

Abstract: A circuit interrupter including a dielectric particle trapping structure interposed between two conductors of a generally concentric arrangement which forms part of the circuit interrupter and to which a high voltage may be applied. The particle trap is particularly adapted for use with a fluid insulating system, more specifically a gaseous insulating medium such as sulfur hexafluoride. The particle trap may be disposed in the vicinity of a critical section of a high voltage conductor, where the presence of extraneous particles of dielectric or metallic material, which are suspended within the fluid may trigger high voltage breakdown if not removed. The particle trap may also be disposed proximate to an inner electrode barrier. Since the particle trap may be a dielectric material which has either corrugations or holes in it, zero or near zero electric fields are created near the holes or depressions. The particle trap allows gravity or the attraction between oppositely charged bodies to actuate charged particles to move into the zero electric field regions and onto the low voltage conductor in the circuit interrupter where the particles discharge any charge thereon. Subsequently, the electric fields in these regions are too low to allow migration of particles to the oppositely charged high voltage electrode.
