AI Technical Summary
In the existing epoxy resin impregnated paper dry oil-SF6 sleeve structure, the spring contact finger mechanism has high requirements for machining accuracy and surface treatment, which leads to increased cost, low assembly reliability, a large number of parts, and a complex assembly process.
A composite connection structure is adopted, which combines double-end welding of conductive rods with resin groove bonding. The spring contact finger mechanism is eliminated. The groove is filled with resin to achieve elastic buffering of the dielectric interface. Combined with modular screw positioning and pressure equalization ball structure, the electric field distribution is optimized.
It simplifies the manufacturing process of parts, reduces processing and production costs, improves sealing reliability and assembly efficiency, and ensures the insulation stability of equipment under high pressure.
