Abstract
The utility model relates to a wind deviation prevention insulator with a stayed insulator, which comprises an upper insulator, a lower insulator, an oblique insulator, a middle hardware and accessories, wherein the oblique insulator is closely fixed on the middle hardware, the integrated insulators form a steady triangle, and the upper insulator, the lower insulator and the oblique insulator are closely fixed on the middle hardware. Simultaneously, an angle between the upper insulator and the oblique insulator can change between 0 and 90 degrees, the oblique insulator can adjust the length thereof on the hardware which is arranged on the end portion of the oblique insulator, and the mounting is convenient. The wind deviation prevention insulator with the stayed insulator is designed aiming to the wind deviation discharge accidents which frequently produce on high voltage transmission lines, the integrated insulators just can produce tiny wind deviation in the situation of strong wind under the support of the triangle, thereby guaranteeing the safety of the transmission lines, and thoroughly putting an end to produce the wind deviation discharge accidents.
Description
Technical field:
The utility model relates to a kind of ultra-high-tension power transmission line and becomes insulator with windproof shift, is used to solve the windage yaw discharge accident that ultra-high-tension power transmission line takes place frequently.
Background technology:
The windage yaw discharge of transmission line is to influence one of problem of line security operation always.In recent years, 110kV～500kV transmission line windage yaw flashover fault frequently takes place, and windage yaw tripping operation tends to cause the unplanned stoppage in transit of circuit, and the unplanned outage rate that is caused by windage yaw is almost 100%.Compare with the tripping operation that thunderbolt waits other reasons to cause, the successful reclosing rate of windage yaw tripping operation is very low, in case the windage yaw tripping operation takes place, the probability that causes circuit to stop transport is just very big.The 6th just has the requirement of discharging at windage yaw specially in " 18 great anti-accident measures of electrical network of State Grid Corporation of China ".
Conventional needle to the major measure of anti-windage yaw is: can take to install additional the measure of weight generally speaking.But actual conditions are: it is relatively poor to adopt the installation weight to improve straight line pole insulator string windage yaw effect, can not satisfy windproof the persisting in of transmission line and ask.
And existing synthetic insulator is little owing to weight, and its windage yaw discharge is just more obvious.
Summary of the invention:
The utility model is exactly the deficiency that the technical problem that will solve overcomes above-mentioned technology exactly, provide a kind of ultra-high-tension power transmission line to become insulator with windproof shift, can iron tower, lead not done under the situation of transformation, directly at existing iron tower and circuit, solve the windage yaw discharge problem of transmission line, improve the safety operation level of circuit.
The utility model is to utilize the triangle stability principle, adopts oblique insulator that bunch of insulator is formed tiltedly and draws, and makes that under than the strong wind effect, bunch of insulator big skew can not take place, and reaches the effect of anti-windage yaw.
A kind of anti-windage yaw insulator that provides according to the utility model with oblique sliding insulator, comprise insulator, following insulator, oblique insulator, middle gold utensil and annex, it is characterized in that: on the gold utensil, on whole insulator, constitute firm triangle in the middle of described oblique insulator is fastened on.
Described insulator, following insulator and the oblique insulator gone up is fastened on the middle gold utensil.
Angle between described upward insulator and the oblique insulator is between 0～90 degree.
Described oblique insulator can be regulated its length at its gold utensil place, end.
A kind of anti-windage yaw insulator with oblique sliding insulator that provides according to the utility model has the following advantages:
1, because the tiltedly existence of insulator, gold utensil in the middle of cooperating makes that the side-play amount under the high wind effect of bunch of insulator is very little, the generation that can thoroughly stop the windage yaw discharge accident.
2, the bottom of going up the top of insulator and following insulator can be adopted and can be had the identical type of attachment of insulator now, makes iron tower and circuit it goes without doing that change can be used, and is quick and easy for installation, especially replacement process.
3, tiltedly the angle between insulator and the last insulator can carry out different designs according to actual conditions, and therefore, tiltedly the mounting points at insulator top can have the multiple choices scheme, and site operation is simple.
4, adopt the windproof shift of this structure to become insulator after, under the situation that satisfies the windage yaw requirement, still have the advantage of synthetic insulator itself, strong, in light weight as: the dirty ability of resistant, be convenient to installation, non-maintaining etc.
Description of drawings:
Be according to the utility model among the figure---a kind of anti-windage yaw insulator with oblique sliding insulator, a kind of embodiment that provides comprises insulator 1, following insulator 2, oblique insulator 3 and middle gold utensil 4; Wherein go up high-pressure side grading shield 11, top gold utensil 12 and bottom gold utensil 13 are arranged again on the insulator 1; Tiltedly on the insulator 3 high-pressure side grading shield 31, top gold utensil 32 and bottom gold utensil 33 are arranged similarly; Upside grading shield 21, bottom side grading shield 22, bottom gold utensil 23 and upside gold utensil 24 are arranged on the following insulator 2; On the middle gold utensil 4 middle grading shield 41 is arranged.
Embodiment:
A kind of embodiment of the present utility model as shown in drawings, a kind of anti-windage yaw insulator with oblique sliding insulator that the utility model provides comprises insulator 1, down insulator 2, tiltedly insulator 3 and middle gold utensil 4;
Wherein, the upside of gold utensil 4 in the middle of the bottom gold utensil 13 of last insulator 1 and oblique insulator 3 and 33 rigidity are fastened on, the downside of gold utensil 4 in the middle of upside gold utensil 24 rigidity of following insulator 2 are fastened on.At this moment, the top of bunch of insulator has just constituted a stable triangle, makes that the windage yaw under the high wind is effectively controlled.
Last insulator 1 and tiltedly insulator 3 top gold utensil 12 with 32 respectively on iron tower suitable location be connected, the bottom gold utensil 23 of following insulator 2 is connected with lead, the connected mode of these three positions can adopt and the identical connected mode of existing structure.
Tiltedly the two ends gold utensil 32 and 33 of insulator 3 can be respectively or all is designed to the gold utensil that length can be regulated, the requirement when satisfying actual installation.The top gold utensil 32 that more convenient, reliable method is oblique insulator 3 is designed to regulate the mode of length.
All grading shields 11,31,21,22,41 only just all need superhigh pressure voltage, when voltage is low, can all or part ofly cancel.
Above preferred embodiment only supplies the usefulness of explanation the utility model, and is not to restriction of the present utility model.Those of ordinary skill in the art under guiding, can also make various distortion and conversion, so all equivalent technical solutions all belongs to protection range of the present utility model in breaking away from spirit and scope of the present utility model.
