Summary of the invention
The purpose of this utility model is to provide a kind of suspension insulator that is applicable to the large discrepancy in elevation, to solve the problems of the technologies described above.
The purpose of this utility model reaches by following measure: the suspension insulator that is applicable to the large discrepancy in elevation, comprise insulator and hanging yoke plate, be mounted with suspension clamp on hanging yoke plate, it is characterized in that: the upper end of described insulator is connected with connection tower gold utensil, the lower end of insulator is connected with rotating asymmetric yoke plate, asymmetric yoke plate is provided with weight, and the two ends of asymmetric yoke plate are connected with hanging yoke plate.
In technique scheme; because the lower end of insulator is connected with rotating asymmetric yoke plate; thereby make suspension clamp both sides discontinuity equalization; the moment that described active force acts on asymmetric yoke plate is not of uniform size; yoke plate is rotated and then automatically to regulate both sides stressed, rotate by suspension clamp self simultaneously and finely tune, finally reach the both sides stress balance; reduced the inclination angle of wire and wire clamp outlet, guardwire is avoided damage.
In technique scheme, the weight on described asymmetric yoke plate is arranged off-centre.When weight adopts the mode of arranged off-centre, can pass through to regulate the weight of weight, thus degree of rotation and the slewing area of further regulating asymmetric yoke plate.
In technique scheme, be provided with the long parts of regulating of string between described asymmetric yoke plate and hanging yoke plate.The long adjusting of described string parts are DB type link plate.After arranging between asymmetric yoke plate and hanging yoke plate that string is long and regulating parts, the staff can be subjected to the force unbalance degree according to the suspension clamp both sides, regulates the long of both sides suspension clamp by going here and there the long parts of regulating, thereby makes suspension clamp both sides stress balance.
In technique scheme, described tower gold utensil comprises the trunnion hanging panel that is positioned at the top, and the lower end edge vertical direction of trunnion hanging panel is connected with the right angle link plate in turn, adjusts plate, U-shaped link and insulator.Described adjustment plate comprises that the DB type is adjusted plate and the PT type is adjusted plate, and the upper end that described DB type is adjusted plate is connected with the right angle link plate, and the lower end that the DB type is adjusted plate connects PT type adjustment plate, U-shaped link successively.The Main Function of trunnion hanging panel is to be connected with shaft tower; The DB type is adjusted plate by different hanging holes, has the long effect of small size adjusting string; The PT type is adjusted plate and is mainly played the effect of significantly regulating insulator string length, is the long critical piece of regulating of string; U-shaped link be mainly to be connected with insulator.
To sum up, suspension insulator described in the utility model adopts the two-wire folder, by with the counterweight arranged off-centre on asymmetric yoke plate, regulate the counterweight on asymmetric yoke plate, rotate suspension clamp and asymmetric yoke plate, the string of regulating insulator string is long, makes suspension insulator both sides maintenance stress balance, reduce the inclination angle of wire clamp outlet wire, avoid the wire damage.
The utility model is compared with the existing duplex two-wire folder suspension insulator that is arranged symmetrically with; can improve the stressing conditions of mountain area straight line pole wire, strain tower wire jumper use suspension insulator; the protection electric wire is avoided damage; improve the fail safe of transmission line weak link; reduce the line upkeep workload; promote the power supply reliability, have good economic benefit and social benefit.
