Abstract
The utility model relating to an anti-tension organic composite insulator series aims at solving the problems that stress of the composite insulator is concentrated and flex resistance is inferior. The structure of the utility model is provided with at least two insulator cells which are connected through connecting hardware fittings. The whole organic composite insulator series can change force directions without destroying the structure of the whole organic composite insulator series. The hard connection between the original single organic composite insulator and a high-voltage line is changed, a soft connection between the organic composite insulator series and the high-voltage line is realized and flexural strength of the organic composite insulator is improved. Concentrated points of stress of the original whole insulator are dispersed on connecting points of each insulator cell. Mechanical strength of the organic composite insulator series is strengthened. The organic composite insulator series can be surely used safely in a long time and the high-voltage line can be operated safely and effectively.
Description
The utility model relates to a kind of insulator of distinguishing by features of shape, specifically a kind of strain resistant organic composite insulator string.
The employed organic composite insulator of high-tension line thoroughly does away with edge plug, organic combined insulated full skirt and is connected gold utensil by one and formed at present, be connected with the connection gold utensil at the two ends of insulation mandrel, several isometrical organic combined insulated full skirts of socket on the insulation mandrel.This organic composite insulator is between the single iron tower and high-voltage conducting wires that is hung vertically in high-tension overhead line, in addition, then is the lateral suspension organic composite insulator at the iron tower turning.Organic composite insulator is when vertical the use, and the suffered hot strength of an elongated insulation mandrel at its center is very high; And when laterally using, not only to bear horizontal pulling force, also to bear and comprise that lead gravity, wind-force etc. and insulation mandrel are the active force of 90 ° of directions.This just requires organic composite insulator not only stronger tensile strength will be arranged, and also will possess higher bending strength simultaneously.Because present organic composite insulator all is single uses, the bending strength of an elongated insulation mandrel is very low in the insulator, stress concentrates on insulation mandrel is connected gold utensil with the end joint portion fully, thereby the insulation mandrel at this position is ruptured, cause the accident of going offline.
The purpose of this utility model just provides a kind of strain resistant organic composite insulator string with high-flexural strength, to guarantee effective operation of high-tension line long-term safety.
The utility model is achieved in that strain resistant organic composite insulator string is to be combined by the connection that connects gold utensil by plural at least insulator unit.Design philosophy of the present utility model is: by designing a kind of short organic composite insulator, form the insulator unit.One of the connection gold utensil at these two ends, insulator unit is the spherical crown shape, and another has spherical inner tank mouths.Several insulator unit are connected in series successively by connecting gold utensil, can form the organic composite insulator string of Len req.Because the connection part of each insulator unit is cooperating of spherical crown and spherical inner tank mouths, make whole organic composite insulator string can change stressed direction, and can not destroy the structure of each insulator unit and even whole organic composite insulator string, so just having changed original single organic composite insulator is connected with the hard of high-tension line, realized being flexible coupling of organic composite insulator string and high-tension line, the bending strength of organic composite insulator is strengthened greatly.The big advantage of another of this organic composite insulator string is, the organic composite insulator string that several insulator unit join and constitute, insulation mandrel has wherein become by original one whole one many sections forms in each unit, can be crooked relatively between each section, thereby the stress concentration point of whole insulator had been distributed on the tie point of each insulator unit originally, strengthen the mechanical strength of organic composite insulator string thus, guaranteed the long-term safety use of organic composite insulator string and the safe and effective operation of high-tension line.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the structural representation of single insulator unit.
As shown in Figure 2, the structural similarity of the structure of the organic composite insulator unit in the utility model and traditional organic composite insulator, promptly be connected with connection gold utensil 1,5, by the silicon rubber integral molded plastic organic combined insulated full skirt 3,4 arranged on the insulation mandrel 2 at the two ends of insulation mandrel 2.Insulator unit connects bulb on the gold utensil 5 and snaps in another insulator unit and connect spherical inner tank mouths on gold utensil 1, can realize interconnecting of two insulator unit.Several insulator unit interconnect, and can form a kind of strain resistant organic composite insulator string (shown in Figure 1).
In Fig. 2, at least 4 organic combined insulated full skirts 3,4 are arranged on each the insulator unit in the insulator string, wherein the diameter of two ends full skirt 3 is greater than the diameter of middle full skirt 4.This structural design has strengthened the air line distance of 3 of two ends big full skirts, promptly increased arcing distance between the air of insulator string, thereby satisfied the electric property requirement of high-tension line better, guaranteed the safe operation of high-tension line organic composite insulator string creepage distance and air arc distance.
