Detailed Description
The utility model relates to a semiconductor lightning and ice protection combined porcelain insulator which comprises an upper accessory 1, a column type porcelain insulator 4 and a steel cap 5.
The upper accessory 1 is the same as the existing structure, is provided with a wire clamp, is fixed at the top end of the column type porcelain insulator 4 and is used for connecting a circuit wire.
The steel cap 5 is also the same as the existing structure, is fixed in 4 bottoms of column type porcelain insulators for connect and fixed insulator and electric power fitting.
The column type porcelain insulator 4 is a porcelain insulator with a column body and an umbrella skirt integrated, wherein the umbrella skirt is in a form that large and small skirts are alternately arranged on the column body, and the large and small umbrella skirts arranged in a special shape enable the insulator to have high insulation, high pollution resistance, high strength and high durability, and the extremely high effect of the effective value of the wet flash voltage resistance in ice and snow and rainstorm weather is improved. By way of example, the column porcelain insulator 4 is 300mm in length, 130mm in small shed diameter, 180mm in large shed diameter and 50mm in shed spacing.
The upper accessory 1 and the steel cap 5 are fixed at two ends of the column-type porcelain insulator 4 by an adhesive 2.
At the top of the shed is a lightning protection ice shield 3, which is the largest umbrella (large needle shield) larger than all sheds. The lightning protection ice cover 3 has the following structure: the outer surface of the needle type large umbrella is coated with a metal oxide semiconductor glaze layer 3.1, the surface resistivity is 100-. The novel semiconductor glaze has good corrosion resistance and larger half-value temperature. The thickness of the metal oxide semiconductor glaze layer 3.1 is 1500-2000 μm.
The metal oxide semiconductor glaze layer 3.1 is a heat conductor glaze with special performance for high-voltage electromagnetism, and the surface resistivity of the glaze is between that of an insulator and a conductor. The glaze is prepared by adding 30-35% of conductive metal oxides of tin, nickel and chromium into common electric porcelain glaze, wherein the proportion of tin, nickel and chromium can be random. Conductivity is obtained when the conductor crystals form a polymeric network. The electrical resistance of the glaze varies as a function of the conductor content in a sigmoidal manner, with the difference in conductivity depending on the shape of the particles and their distribution in the glaze. The microstructure formed is different from that of ordinary glaze. Besides a large amount of glass phase and a small amount of bubbles, the semiconductor glaze also contains conductive crystals or solid solutions with various forms, and the conductive phases penetrate through the glass matrix to form an uninterrupted conductive network. Tin oxide, nickel, chromium glazes are currently considered to be the best semiconductive metal glazes.
