Abstract

The invention discloses a power insulator with a protective structure at the edge, which comprises a ceramic insulator, wherein a protective component is arranged at the outer end of the ceramic insulator, a slot is arranged in the center of the ceramic insulator, a plurality of groups of ceramic insulators are arranged, an upper resin rod and a lower resin rod are respectively inserted into the slots at the two ends of the plurality of groups of ceramic insulators, a middle resin rod is inserted into the slot between the upper resin rod and the lower resin rod, fixing seats are fixedly arranged at the separated ends of the upper resin rod and the lower resin rod, and a fastening component is arranged at one side of each fixing seat. According to the invention, as the flashover phenomenon of discharge breakdown occurs between adjacent ceramic insulators, the protective component can effectively protect the edges of the ceramic insulators, damage caused by overlarge stress at the edges is avoided, and the sunk sealing groove is matched with the upper jacket to form a transitional umbrella skirt-shaped cambered surface with the umbrella-shaped surface of the ceramic insulators, so that water drops cannot be gathered on the surface, the electric conductivity can be reduced by rapid running, and the safety is improved.
