Pin-type transparent insulator

Abstract

The invention discloses a pin-type transparent insulator which comprises a hold-down plate, a flat-topped umbrella skirt, a flat-topped umbrella skirt center cylinder, a connecting rod, a metal sleeve, and a bearing bolt, wherein the hold-down plate, the flat-topped umbrella skirt, the flat-topped umbrella skirt center cylinder, the connecting rod, the metal sleeve and the bearing bolt are connected in sequence. According to the transparent insulator, the large umbrella skirt and the flat-topped umbrella skirt center cylinder are made of polycarbonate, and the connecting rod is made of epoxy resin, so that the insulation effect is enhanced greatly, the transparency is good, and when there is a fracture or breakdown failure accident, timely repair can be conducted to ensure safe running of lines. The insulator has the advantages of reasonable structure, low weight, safe and reliable performance, easy manufacture, low cost, and easy installation and use, and has good economic and social benefits.

Description

technical field [0001] The invention belongs to the technical field of power transmission accessories, and relates to an insulator for a power line, specifically a pin-type transparent insulator. Background technique [0002] Pin-type insulators used in overhead distribution lines. Traditional pin-type porcelain insulators are composed of porcelain parts and iron feet extending into the porcelain parts. The iron feet are installed inside the porcelain parts and then glued with cement, which can directly withstand bending. Load, good bending performance. The main fixing method of the wires fixed by pin insulators is generally the binding wire winding method. The binding wire winding method is not only complicated in binding, but also has low installation efficiency. There are also some problems in the structure: aluminum stranded wire and steel core aluminum stranded wire The wire materials are the same, and the wires are affected by weather conditions such as wind, ice, and...

AI Technical Summary

Problems solved by technology

The main fixing method of the wires fixed by pin insulators is generally the binding wire winding method. The binding wire winding method is not only complicated in binding, but also has low installation efficiency. There are also some problems in the structure: aluminum stranded wire and steel core aluminum stranded wire The wire materials are the same, and the wires are 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 out, and then disconnection occurs; Aging and falling off under the wind and sun, loosening and unstable fixation, the exposed iron wire cuts the outer layer of the wire insulation and breaks the outer insulation, and further cuts the wire

The replacement of aluminum binding wires is invalid and cannot be reused. A large number of aluminum binding wires must be replaced every year. The workload is heavy and the labor intensity of the workers is high. When the porcelain insulator breaks, it is not easy to find, and the wires are not fixed firmly, which poses a safety hazard.
