Fracture-preventing insulator

Abstract

The present invention belongs to the insulator technology field, and relates to a fracture-preventing insulator. The insulator comprises an upper steel plate, a lower steel plate, an insulator body, an umbrella skirt, insulation fiber ropes, a short fiber and a super hydrophobic layer. The insulator body is internally provided with a plurality of insulation fiber ropes, the upper steel plate and the lower steel plate, the upper steel plate is provided with an upper nut, the upper nut and the upper steel plate are integrated, the lower steel plate is provided with a lower nut, the lower nut and the lower steel plate are integrated, two ends of each insulation fiber rope are respectively bound at the upper steel plate and the lower steel plate, the insulator body is internally provided with at least three embedded strain gauges, and the height of each embedded strain gauge is the same. The fracture-preventing insulator monitors stresses of the insulator at different positions to determine whether the insulator generates cracks or not, and if the insulator generates cracks, the insulator is replaced in time.

Description

Technical field [0001] The invention belongs to the technical field of insulators and relates to an anti-fracture insulator. Background technique [0002] As an indispensable component in transmission lines, insulators are used in very large quantities. Insulators play an insulating role. In addition to their own insulation capabilities, insulators have very high requirements on the surface of insulators. If the surface of insulators is dusty or frozen, the insulation performance will be reduced. The distance between the surface of the umbrella skirt between the two ends of the insulator is called the creepage distance. The purpose of setting the umbrella skirt is to prevent the surface pollution of the insulator from affecting the insulation. Traditional porcelain insulators require manual cleaning of surface contaminants, which is troublesome to clean. Some technologies install ice-breaking devices and wind-driven cleaning devices on the porcelain insulators. Not to mention the...

Problems solved by technology

The composite insulator core is generally composed of epoxy resin and fiber, and in order to increase the anti-fouling ability, some composite insulators are coated with super-hydrophobic coating on the surface. Poor performance, poor resistance to lightning impact, insufficient wear resistance, with prolonged use, wind and sun, and may be pecked by birds, resulting in peeling of the surface and los
