Abstract
The utility model discloses a bilaterally symmetrical windage yaw resistant insulator set. The bilaterally symmetrical windage yaw resistant insulator set comprises a windage yaw resistant insulator set unit and a fixed plate; the windage yaw resistant insulator set unit comprises an upper insulator string, a left diagonal insulator string, a right diagonal insulator string and a lower diagonal insulator string; an upper portion of the fixed plate is regular-triangle-shaped, a lower portion of the fixed plate is rectangle-shaped, and the regular triangle and the rectangle are of an integrated structure; lower ends of the upper insulator string, the left diagonal insulator string and the right diagonal insulator string are respectively hinged to three vertexes of the regular triangle at the upper portion of the fixed plate through hinged shafts; and an upper end of the lower insulator string is hinged to a lower end of the rectangle at the lower portion of the fixed plate through a hinged shaft. When the bilaterally symmetrical windage yaw resistant insulator set is used, an upper end of the upper insulator string is installed on an iron tower, and the lower insulator string is fixedly connected with the upper insulator string through the fixed plate; and then installation positions of the left diagonal insulator string and the right diagonal insulator string are adjusted according to actual space of the iron tower. Due to the fact that the upper insulator string, the left diagonal insulator string and the right diagonal insulator string are all fixed on the iron tower, influence of windage yaw on a power transmission and transformation line by wind can be prevented in double aspects.
Description
Technical field:
The utility model relates to a kind of insulation subgroup, particularly relates to a kind of symmetrical wind-deviation insulation subgroup, belongs to the jockey of high voltage power transmission and transforming circuit.
Background technology:
The windage yaw ground connection of transmission line is one of problem affecting line security operation always, insulator windage yaw ground connection refers to that suspension insulator departs from upright position and causes certain phase line-to-ground to the skew of steel tower tower body under strong wind condition, this type of accident occurs a lot of in recent years at 110kV Above Transmission Lines, have a strong impact on and threaten the safe operation of network system.In existing power circuit, traditional wind-deviation mode is that weight is installed in insulator lower end, and fix external cable by common wire clamp is installed, improving insulator string windage yaw although this with weight has certain effect, can not really control the windage yaw of insulator; Adopt in addition common wire clamp to fix external cable, even wave through frequent vibration, external cable is is easily worn and torn by wire clamp.
Utility model content:
Technical problem to be solved in the utility model is: a kind of simple in structure, reasonable in design, the symmetrical wind-deviation insulation subgroup that can guarantee safe operation of power system is provided.
The technical scheme that the utility model is taked for technical solution problem is:
A kind of symmetrical wind-deviation insulation subgroup, comprise wind-deviation insulation subgroup and fixed head, described wind-deviation insulation subgroup comprises insulator string, left oblique pull insulator string, right oblique pull insulator string and lower insulator string, and described upper insulator string, left oblique pull insulator string, right oblique pull insulator string and lower insulator string are hinged on fixed head by jointed shaft respectively.
Described fixed head top is equilateral triangle shape, bottom rectangular in shape, and described equilateral triangle and rectangle are integral type structure.
The lower end of described upper insulator string, left oblique pull insulator string and right oblique pull insulator string is hinged on three summits of fixed head top equilateral triangle by jointed shaft respectively; The rectangular lower end in the upper end of described lower insulator string and fixed head bottom is hinged by jointed shaft.
When use, the upper end of upper insulator string of the present utility model is arranged on steel tower, lower insulator string is fixed together by fixed head and upper insulator string; Then adjust the installation site of left oblique pull insulator string and right oblique pull insulator string according to the real space of steel tower.After installing, because upper insulator string, left oblique pull insulator string and right oblique pull insulator string are all fixed on steel tower, thereby from having prevented on both side the windage yaw shadow of wind to power transmission and transformation line.
Due to all hinged by jointed shaft between of the present utility model and insulator string and fixed head, can adjust according to the real space of steel tower the installation site of insulator string, there is good wind-deviation effect.
Because fixed head of the present utility model top is equilateral triangle shape, bottom rectangular in shape, is zhou duicheng tuxing again, makes like this insulation subgroup of the present utility model form symmetrical trend, has also played to a certain extent the effect of wind-deviation
The utility model is simple in structure, reasonable in design, can play good wind-deviation effect, guarantees the safe operation of electric power system, has very strong practical value.
Accompanying drawing explanation:
Fig. 1 is structural representation of the present utility model.
Embodiment:
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to Fig. 1, a kind of symmetrical wind-deviation insulation subgroup, comprises wind-deviation insulation subgroup and fixed head 5, and wind-deviation insulation subgroup comprises insulator string 1, left oblique pull insulator string 2, right oblique pull insulator string 3 and lower insulator string 4; Described fixed head 5 tops are equilateral triangle shape, bottom rectangular in shape, and equilateral triangle and rectangle are integral type structure; The lower end of described upper insulator string 1, left oblique pull insulator string 2 and right oblique pull insulator string 3 is hinged on three summits of fixed head 5 top equilateral triangles by jointed shaft respectively, and the upper end of lower insulator string 4 and fixed head 5 rectangular lower ends, bottom are hinged by jointed shaft.
When use, the upper end of upper insulator string 1 of the present utility model is arranged on steel tower, lower insulator string 4 is fixed together by fixed head 5 and upper insulator string 1; Then adjust the installation site of left oblique pull insulator string 2 and right oblique pull insulator string 3 according to the real space of steel tower.After installing, because upper insulator string 1, left oblique pull insulator string 2 and right oblique pull insulator string 3 are all fixed on steel tower, thereby from having prevented on both side the windage yaw shadow of wind to power transmission and transformation line.
The above; it is only preferred embodiment of the present utility model; not the utility model is done to any pro forma restriction; any simple modification, equivalent variations and modification that every foundation technical spirit of the present utility model is done above embodiment, within all still belonging to the protection range of technical solutions of the utility model.
