This invention relates to the field of insulation technology for DC gas-insulated
metal-enclosed
switchgear, and discloses a self-dispersing charge basin insulator and a self-dispersing method, comprising a central insert, an insulating component, a
metal flange ring, and several permanent
magnet vibration damping cover assemblies; the central insert is embedded within the insulating component; the
metal flange ring surrounds the outer periphery of the insulating component; several annular grooves are formed circumferentially on the metal
flange ring; the several permanent
magnet vibration damping cover assemblies are correspondingly embedded in the several annular grooves; the permanent
magnet vibration damping cover assemblies are used to form a
magnetic field parallel to the surface of the insulating component, so as to deflect the charges moving towards the surface of the insulating component through the
Lorentz force, thereby reducing charge accumulation. This invention solves the problem that traditional passive protection cannot dynamically suppress charge accumulation, while having a high degree of overall structural integration, without increasing the size of the equipment, and can be adapted to the use scenarios of compactly arranged power stations and converter stations.
