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
What the present invention relates to is the high-tension insulator field, and what be specifically related to is the special-purpose cap and pin insulator of a kind of strain insulator circuit.
Background technology
Insulator is a kind of special insulation control, can play an important role in overhead transmission line.Insulator is used for electric pole more early, slowly develops in an end of high-tension bus-bar connection tower to have hung the insulator of a lot of plate-likes, and it is made by glass or pottery usually in order to increase creepage distance, just is insulator.
Along with developing rapidly of World Economics, the electrical network of various countries is flourishing day by day.The various component demands of using in the electrical network stringing also constantly increase, and insulator is exactly wherein a kind of, and it can guarantee that lead and cross-arm, shaft tower have enough insulation.Therefore, the quality of insulator is crucial to the safe operation of circuit.
As shown in Figure 1, the single umbrella plate shape suspension insulator that uses on the current power circuit comprises umbrella disk 1 and is arranged on umbrella disk central authorities, be roughly the head 2 of column, this insulator is umbrella disk 1 and has umbrella rib 3, this kind structure both can be used for the string that dangles, also can be used for strain insulator-string, strain insulator-string is a horizontal direction with the insulator hang, and the wind and rain self-cleaning of product is good; But the umbrella rib 3 of this umbrella disk 1 is dark umbrella rib, so upper and lower surface voltage is inhomogeneous respectively, makes Leakage Current produce the electric arc bridge joint easily, influences the anti-filthy performance of product, has reduced creep distance validity and resistant lightning and has pressed.
Summary of the invention
At the deficiency that exists on the prior art, the present invention seeks to be to provide a kind of upper and lower surface voltage that makes to be more evenly distributed, improve the special-purpose cap and pin insulator of strain insulator circuit of creep distance validity and pollution flashover voltage, prevent the electric arc bridge joint, strengthened anti-fouling effect.
To achieve these goals, the present invention realizes by the following technical solutions:
The special-purpose cap and pin insulator of strain insulator circuit, it comprises umbrella disk and column head, it is characterized in that be provided with one on the upper surface of described umbrella disk at least and go up the umbrella rib, its lower surface is provided with a plurality of subumbrella ribs, the described standard umbrella shape that goes up umbrella rib and two series connection of subumbrella rib formation, be provided with the umbrella rib up and down by umbrella disk, its upper and lower surface voltage is more evenly distributed, creep distance validity is higher, dirty umbrella voltage is higher, and anti-fouling effect strengthens.
According to the special-purpose cap and pin insulator of above-mentioned strain insulator circuit, wherein, umbrella disk umbrella rib up and down requires according to properties of product and decides.
According to the special-purpose cap and pin insulator of above-mentioned strain insulator circuit, wherein, described umbrella disk from inside to outside last umbrella rib and the rib height of subumbrella rib increase progressively gradually.
According to the special-purpose cap and pin insulator of above-mentioned strain insulator circuit, wherein, what the special-purpose cap and pin insulator of described strain insulator circuit adopted is glass, pottery or other insulating material.
The present invention is by all being provided with the umbrella rib up and down with the insulator umbrella disk, and head is a column structure, is used for strain insulator-string.This kind insulator is compared with dark umbrella rib insulator, and subumbrella rib is all more shallow on it, can reduce the height of rib effectively, not only can improve the wind and rain self-cleaning property, and Leakage Current trends towards preventing the electric arc bridge joint along the umbrella edge surface the anti-filthy performance of raising product.And dark umbrella resistant umbrella shape is changed into the standard umbrella shape of two series connection, and upper and lower surface voltage is more evenly distributed, creep distance validity is higher, and pollution flashover voltage is higher, has strengthened anti-fouling effect.
