Abstract
The utility model discloses an L-string suspension connecting plate used for a small-angle straight-line tower of a UHV transmission line. Six wire clip mounting holes for conducting wire connection are arranged on a plate body and are located on the same circumference and are evenly arranged; two L-shaped insulator string connection holes are arranged at the outer side of the circle where the six wire clip mounting holes are located, and the distances from the two connection holes to the center of the circle where the six wire clip mounting holes are located are equal. The L-string suspension connecting plate used for the small-angle straight-line tower of the UHV transmission line adopts an integral-type plate body, has simple structure and good stability, can effectively control the shape of the conducting wire split circle at a hanging point of the conducting wire, and solves the problem that the conducting wire collides with the connecting plate.
Description
Technical field
The utility model belongs to a kind of electric armour clamp, and the little corner tangent tower of particularly a kind of UHV transmission line is with the L string yoke plate that dangles.
Background technology
At present, the little corner pole of straight line band has been widely used in the domestic conventional 500kV power transmission sequence engineering, is making things convenient for line design and is reducing and to have played important effect aspect the project cost.With respect to the little corner pole of tape; there is following shortcoming in strained angled tower: the insulator consumption is big, wire jumper is installed complicated; and easily break down in wire jumper drainage plate joint; project installation expense and maintenance workload have been increased; the protection gold utensil is many; every Ji Ta need install weight, jumper wire spacing rod, and steel basis consumption is big, makes the body expense of circuit strengthen thereupon.On the other hand, strain tower is a weak link of line insulation, lightning protection, and many flashover faults take place frequently on strain tower, and the safe operation of returning circuit that increases of strain tower has brought certain hidden danger.Therefore, at the characteristics of China's extra high voltage line, design a kind of tangent tower with less corner and will have the important engineering practical significance, this will make China's ultra high voltage power transmission sequence, and will be more advanced technically, more reasonable economically.
L string is little corner tangent tower with dangle vitals in going here and there of L type with the yoke plate that dangles, and mainly bears the wind-force of weight, icing weight and the horizontal direction of vertical direction lead.Lead is connected with yoke plate by suspension clamp, guarantees its division number and spacing by yoke plate.What existing little corner tangent tower dangled that yoke plate in the string adopts with the L type is split type yoke plate, last lower linking plate adopts a string or two string gold utensils link to each other, when stringing finish lead stressed after, lead division change of shape, cause every root lead heading spacing inconsistent, sub-conductor is not in orbicular periphery, lead and the yoke plate phenomenon that collides occurred.
The utility model content
The purpose of this utility model provides the little corner tangent tower of a kind of UHV transmission line with the L string yoke plate that dangles, and is intended to lead division garden, effective pilot hanging point place shape, solves the problem that lead and yoke plate are collided.
The purpose of this utility model is achieved in that the little corner tangent tower of a kind of UHV transmission line with the L string yoke plate that dangles, has 6 wire clamp installing holes that connect as lead on the plate body, and these 6 wire clamp mounting hole site and evenly are provided with on same circumference; The outside that is positioned at 6 wire clamp installing hole place circles on the plate body has two L type insulator string connecting holes, and this two connecting hole equates with the distance in the center of circle of 6 wire clamp installing hole place circles.
Also have construction on the above-mentioned plate body and use the hole, this construction is positioned at the round outside, 6 wire clamp installing hole places with the hole, and equates with the distance of two connecting holes.
The medium position place of 6 wire clamp installing hole place circles also has lightening hole on the above-mentioned plate body.
When adopting L type insulator string, two strings are connected with two connecting holes of yoke plate respectively, and the extending line intersection point and the lead application point of two strings coincide, this will produce an additional moment, and make the yoke plate run-off the straight of L type insulator string, and for the balance yoke plate, must be with the hanging point integral translation of L type string on yoke plate, to offset the suffered unbalanced moments of yoke plate, guarantee not run-off the straight substantially under the average temperature of the whole year condition.In addition, wire clamp has certain inclination angle, has considered the collision problem of wire clamp when the design yoke plate emphatically.In addition, on yoke plate, also be provided with 6 wire clamp installing holes.
Compared with prior art, the technical scheme that provides of the utility model embodiment has the following advantages and characteristics:
The utility model provides the little corner tangent tower of a kind of UHV transmission line with the L string yoke plate that dangles, and yoke plate is an integral type, the pattern good stability, and the gold utensil part is few, and is simple in structure.Effectively pilot hanging point place lead division toroidal prevents the problem that lead and yoke plate are collided.
Description of drawings
Fig. 1 is this novel structural representation.
Embodiment
Describe in detail below in conjunction with accompanying drawing.
As shown in the figure, the utility model is the little corner tangent tower of a kind of UHV transmission line with the L string yoke plate that dangles, L type insulator string both sides are connected with two connecting holes 1,2 of yoke plate respectively, and the extending line intersection point and the lead application point of two strings coincide, to offset the suffered unbalanced moments of yoke plate; Have 6 wire clamp installing holes 3,4,5,6,7,8 on the plate body, six wire clamp mounting hole site are on same circumference, and evenly be provided with, to satisfy the spacing requirement of transmission line, the outside that is positioned at 6 wire clamp installing hole place circles on the plate body has two L type insulator string connecting holes 1,2, and this two connecting hole equates with the distance in the center of circle of 6 wire clamp installing hole place circles.
Also have construction on the plate body and use hole 9, this construction is positioned at the round outside, 6 wire clamp installing hole places with hole 9, and equates with the distance of two connecting holes 1,2.The medium position place of 6 wire clamp installing hole place circles also has lightening hole 10 on the plate body.
Fig. 1 illustrates an example of plate shape.Satisfying under the plate body tensile strength prerequisite, other position cutting of plate body is being removed or hollowed out, to reach weight loss effect.
