Title:
METHOD FOR TREATING SURFACE OF ARC EXTINGUISHING CHAMBER, AND ARC EXTINGUISHING DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/021374
Kind Code:
A1
Abstract:
The present application provides a method for treating the surface of an arc extinguishing chamber, and an arc extinguishing device. The method comprises: sleeving an annular shielding net on the outer side of an arc extinguishing chamber, the annular shielding net being equipotentially connected to a shielding cover arranged in the arc extinguishing chamber; cleaning and heating the arc extinguishing chamber sleeved with the annular shielding net, and then coating the surface with silicone rubber to obtain a rubber-coated arc extinguishing chamber; activating the silicone rubber on the surface of the rubber-coated arc extinguishing chamber to obtain an activated rubber-coated arc extinguishing chamber; and injecting epoxy resin into the activated rubber-coated arc extinguishing chamber, curing, and naturally cooling. According to the present application, on one hand, the electric field intensity of the silicone rubber surface on an inner side of the annular shielding net is led to the middle of an epoxy resin material by means of the annular shielding net, and the insulation strength of the arc extinguishing chamber is increased by means of shielding, and on the other hand, plasma activation treatment is carried out on the silicone rubber on the surface of the arc extinguishing chamber, and then epoxy resin casting is carried out, thereby solving the problem of creeping discharge of a 35 kV solid insulated arc extinguishing chamber.
