High-pressure pin insulator with fixed wire fitting

Abstract

The invention relates to a high-pressure pin insulator with a fixed wire fitting. The high-pressure pin insulator comprises a porcelain insulator body and the fixed wire fitting. The fixed wire fitting is composed of two threaded zinc sleeves arranged on the upper portion of the porcelain insulator body, and a wire pressure plate is arranged on the threaded zinc sleeves and is locked through stainless steel bolts. A steel pin is arranged on the lower portion of the porcelain insulator body, one end of the steel pin is inserted into the porcelain insulator body, and the other end of the steel pin is arranged on a cross arm of a telegraph pole.

Description

technical field [0001] The invention relates to power distribution equipment, in particular to a high-voltage pin insulator with a fixed wire fitting. Background technique [0002] With the sustained and rapid development of the national economy, my country's electric power industry presents a trend of rapid development. Facing the huge market space for power demand and power supply construction, my country's power grid is faced with the arduous task of continuously increasing transmission capacity and safely and reliably transporting large-scale power from power plants to end users. The short-term and long-term grand goals of the national large power grid construction have brought rare development opportunities to the production of my country's ceramic insulator industry, and at the same time put forward higher requirements for the performance and quality of ceramic insulators. [0003] At present, the main fixing method of the high-voltage pin insulators used in 10KV over...

Problems solved by technology

[0003] At present, the main fixing method of the high-voltage pin insulators used in 10KV overhead distribution lines is the wire binding method. The wire binding method is not only complicated, but also has low installation efficiency. There are also some problems in the structure: aluminum stranded wire The binding material of the steel-cored aluminum stranded wire is the same as that of the wire. The wire is affected by weather conditions such as wind, ice, and low temperature all the year round, and strong vibrations often occur, causing the contact parts to wear and tear, and then the wire breakage occurs; the wire with insulation is used with a sheath The iron binding wire, the outer skin of the iron binding wire is aging and falling off under the wind and the sun, and it becomes loose, making the fixation unreliable. The exposed iron wire cuts the outer layer of the wire insulation and breaks the outer insulation, and further cuts the wire
