Disk-shaped suspension insulator special for tension resisting circuit

Abstract

The invention relates to a disk-shaped suspension insulator special for a tension resisting circuit. The disk-shaped suspension insulator comprises an umbrella disk and a columnar head, wherein at least one upper umbrella edge is arranged on the upper surface of the umbrella disk; a plurality of lower umbrella edges are arranged on the lower surface of the umbrella disk; and the upper umbrella edge and the lower umbrella edges form two serially-connected standard umbrella shapes. In the invention, the umbrella edges are arranged on the upper part and the lower part of the insulator umbrella disk; and the head has a columnar structure for tension resisting strings. Compared with a deep umbrella edge insulator, the disk-shaped suspension insulator has the advantages that: the upper and lower umbrella edges of the insulator are shallower for effectively reducing the height of the edges; the insulator can improve wind and rain self-cleaning performance, and the leakage current tends to the surface of the umbrella edge so as to prevent arc bridge connection and improve anti-pollution performance of the product; and the deep umbrella anti-pollution umbrella shape is changed into two serially-connected standard umbrella shapes, and the voltage is uniformly distributed on the upper and lower surfaces so that the creeping distance effectiveness is higher, the pollution flashover voltage is higher and the anti-pollution effect is improved.

Description

technical field [0001] The invention relates to the field of high-voltage insulators, in particular to a disc-shaped suspension insulator for strain-resistant lines. Background technique [0002] Insulators are special insulation controls that can play an important role in overhead transmission lines. In the early years, insulators were mostly used on utility poles. Slowly, many disk-shaped insulators were hung on one end of the high-voltage wire connection tower. It is to increase the creepage distance. It is usually made of glass or ceramics, and it is called an insulator. [0003] With the rapid development of the world economy, the power grids of various countries are increasingly developed. The demand for various components used in power grid wiring is also increasing, and insulators are one of them, which can ensure sufficient insulation of wires, cross arms, and towers. Therefore, the quality of the insulator is very important to the safe operation of the line. ...

AI Technical Summary

Problems solved by technology

[0004] like figure 1 As shown, the single-umbrella-shaped suspension insulators currently used on power lines include an umbrella plate 1 and a roughly columnar head 2 arranged in the center of the umbrella plate. The structure can be used not only for hanging strings, but also for tension strings. The insulators used for tension strings are suspended in a horizontal direction, and the product has good self-cleaning performance in wind and rain; but the umbrella edge 3 of this umbrella plate 1 is a deep umbrella edge, so the vertical The surface voltage is uneven, which is easy to cause arc bridging of leakage current, which affects the anti-pollution performance of the product and reduces the effectiveness of creepage distance and anti-pollution flashover voltage
