Abstract
The invention relates to an extra-high voltage overhead power transmission line insulator chain type structure, and particularly relates to a three-to-two connection fitting and an insulator chain using the connection fitting. The three-to-two connection fitting comprises an upper plate and a lower plate which are vertically hinged. The upper plate is provided with connection holes which are arranged in a spacing way in a left-and-right direction and used for being connected with triple insulators respectively. The lower plate is provided with installing holes which are arranged at the left and right sides of the hinged part respectively and used for installing suspension clamps in a hinged way. The three force bearing points of the upper plate are converted into two force bearing points of the two sides of the lower part so that the structure is simple, center height is reduced and onsite installation is facilitated. Force bearing balance of the left and right sides can be automatically adjusted by the suspension clamps installed on the lower plate so that installation of conductive wires is facilitated, imbalance caused by tower position height difference and conductive wire ice coating can also be automatically adjusted and thus the strain type is ensured to be steady and safe.

Accompanying drawing explanation
Fig. 1 is that the present invention three becomes in the specific embodiment of two connection gold utensils and connects structural representation gold utensil being installed suspension clamp;
Fig. 2 is the left view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.
Of the present invention three become the specific embodiment that two connect gold utensil, as shown in Figure 1 to Figure 2, three become two connection gold utensils comprises upper plate 1 setting up and down and lower plate 2, it is hinged that the first bolt 3 is passed through on the bottom of upper plate 1 and the top of lower plate 2, upper plate 1 is single plate structure, lower plate 2 is double plate structure, and lower plate 2 comprises two points of plates that time interval be arranged in parallel, and hinged place upper plate 1 is between two points of plates.On upper plate 1, left and right is evenly equipped with three connecting holes 11 for being connected with three insulators respectively, and left and right sides lower plate 2 being positioned at the first bolt 3 is respectively equipped with the installing hole for hinged installation suspension clamp 5, is coated with the second bolt 4 in installing hole.Upper plate 1 is symmetrical set square structure, and the connecting hole 11 and the first bolt 3 that are positioned at centre are positioned in symmetrical center line, and the connecting hole 11 of both sides is positioned at two summits place of set square.The top of upper plate 1 is provided with two flanges be positioned at above connecting hole 11, and two flanges lay respectively in three connecting holes between adjacent two connecting holes in the lateral direction, and each flange is provided with two apertures 12 for installing insulating grading ring.The bottom of lower plate 2 has the protuberance be positioned at below installing hole.
