Description
Technical field
The present invention relates to used for transmission line insulator hardware string, particularly triple strain insulator string for ultra-high voltage transmission line.
Background technology
For the extra high voltage line engineering, the raising of electric pressure, the increasing of connection spacing, increasing of lead division number proposed challenge to gold utensil structural design and reasonable Arrangement.The triple strain string of existing six division electricity transmission lines adopts all presses shading ring, has the problem that other gold utensil string is installed that influence, its two, what have the triple strain string now respectively joins the stressed defectives such as inhomogeneous, that layout is not compact that exist.
Summary of the invention
The purpose of this invention is to provide stressed even, the equally distributed triple strain insulator string for ultra-high voltage transmission line of assurance six-multiple conductor between a kind of more reasonable structure, connection.
The object of the present invention is achieved like this: a kind of triple strain insulator string for ultra-high voltage transmission line, comprise hanging point gold utensil, insulator, strain insulator ply-yarn drill, insulator is three, articulate ball-eye on each insulator one end, the ball-eye other end is hinged on to be adjusted on the plate, has a curved round eye on the fanning strip face of adjustment plate; Described hanging point gold utensil cover hangs on the U-shaped link, and U-shaped link openend is hinged on the eyelet adjusting plate; Two two become three yoke plates and are fixedly connected, the other end of three insulators is hinged on connecting firmly on the body of two two change three yoke plates through socket-clevis eye respectively, two become the tetrad plate is connected with two two bodies that are connected that become three yoke plates through two link plates, yoke plate is fixed on two through the right angle link plate and becomes on the tetrad plate, the yoke plate upper edge is same to be evenly distributed in as by fixing six eyelets of six-multiple conductor of gold utensil string, is connected with identical gold utensil string on each eyelet; Described strain insulator ply-yarn drill is hinged on another through the U-shaped link and adjusts on the plate, have a curved round eye on the fanning strip face of another adjustment plate, the second right angle link plate is hinged on another eyelet adjusting plate, and the first right angle link plate is connected between the eyelet of the second right angle link plate and yoke plate; All pressing plate is fixed on connecting firmly on the body of two two change three yoke plates, and two shading rings are fixed on two and become on the tetrad plates.
Compared with prior art, the present invention has following characteristics and advantage:
1, for grading ring, shading ring, because after electric pressure improves, main ring pipe enlarged diameter, all pressures shading ring that six division electricity transmission lines relatively in the past---engineering is used, this insulator string is with grading ring and separately design of shading ring, opposition is finished its electric function separately, has guaranteed that effectively insulator string voltage distributes to the requirement of the anti-height of grading ring.For ease of installing, also grading ring is designed to split typely, shading ring is designed to wheel shape, can be stable be installed on the yoke plate.
2, owing to be used for extra high voltage line, the insulator yoke plate increases, and the connection spacing strengthens, in insulator string, become three yoke plates with interface hanging hole number by adopting two, become two by three, and guarantee respectively to join stressed evenly, connect reliable, above three hanging holes link to each other with insulator string by socket-clevis eye.Below two hanging holes become the tetrad plates by parallel link plate and two and link to each other, to finish the function of insulator string three changes two.Consider this two change three yoke plates residing position in insulator string, installing hole at its position of centre of gravity design grading ring, make the serial type compact in design, become the connection formula of three yoke plates with respect to other three insulator strings two, two yoke plates combined about this yoke plate adopted, yoke plate is the veneer form, and reserves the installing hole of grading ring at position of centre of gravity.
3, employing two becomes the tetrad plates, yoke plate becomes to make up yoke plate with supporting framework, finishes six divisions by the combination yoke plate again with yoke plate and connects up, and upper and lower two-layer gold utensil string installs bracing frame additional at combination yoke plate place.Because the increase of insulator series connection spacing by this Combination Design, has been finished the transition that insulator string connects to bundle conductor, its version can guarantee effectively that six roots of sensation bundle conductor is evenly distributed on each summit of regular hexagon.Because this yoke plate is made separate assembling, effectively dissolving the weight of finishing the increase of structure size and bringing increases.Because two become tetrad plate residing position in string, are reserved with the installing hole of shading ring in its both sides.Relative other extra high voltage line, shading ring is designed to the loop configuration perpendicular to circuit, and second shading ring is installed on the special lead spacer, and the vibration that the installation centering is all inconvenient, simultaneously long-term also can increase the fatigue of lead.This insulator string shading ring is installed on this yoke plate as load spare along circuit, can not apply any additional force to lead, also is convenient to construction simultaneously, installs.
