LEAKAGE BLOCKING AND FEEDING METHOD OF INSULATION MEDIUM FOR TRANSFORMER AND PAD SWITCH

摘要

PURPOSE: A method for reinforcing an electric insulation box of a ground device at a live line state and a method for supplementing an insulation medium are provided to reduce damage due to power failure by supplementing the insulation medium at the live line state after reinforcing the electric insulation box. CONSTITUTION: The leakage of an insulation medium from an electric insulation box is tested(S10). The leakage part of the insulation medium of the electric insulation box is cleaned(S40). A pre-coating film is formed on the leakage part of the insulation medium of the electric insulation box(S50). An epoxy resin is firstly and secondly coated on the pre-coating film(S60,S70). The insulation medium is supplemented to the electric insulation box at a live line state by an insulation medium supplement device(S80). The amount of the insulation media and the electric insulation are finally checked(S90).
