| Zusammenfassung: | The invention discloses an air-leakage electrified under-pressure plugging method for gas-insulated switchgear. The air-leakage electrified under-pressure plugging method comprises the steps of determining a defect repairing region of a gas-insulated switchgear shell, performing uniform mixing on a base material and a curing agent according to specific proportions to form modified epoxy resin, and uniformly coating the equipment defect repairing region with the modified epoxy resin within curing time; sticking a rigid constraint apparatus on the shell by adopting the formed modified epoxy resin to enable an SF6 gas to be leaked from reserved holes in the rigid constraint apparatus; after the formed modified epoxy resin is fully cured, sealing the rigid constraint apparatus to complete temporary plugging of the SF6 gas; uniformly applying silicon-steel-containing modified epoxy resin on the rigid constraint apparatus to form an adhesive layer after the silicon-steel-containing modified epoxy resin is cured so |
