Two-component glue was used to block gas leakage of SF6 insulated power apparatus.From the field experiment

gas leakage blocking with a pressure of 0.3～0.6 MPa was realized by using Nanon inorganic filler bonding agent.The blocking technique is very simple

and is applicable to the field operation.The blocking effect was investigated by the infrared-laser-image technique.Moreover

leakage status before and after blocked were measured based on the technology of infrared-laser imaging.Combined with halogen leak locator the long-term leakage after blocked was analyzed.It is shown that the technique and material proposed in this paper can realized well gas leakage blocking in power apparatus.
