Description
Technical field
The utility model relates to a kind of high-tension line wiring system, relates in particular to a kind of supertension line system.
Background technology
The gold utensil that China's 500kV supertension line adopted in the past is to continue to use the national gold utensil Uniting of making typical gold utensil series and finishing in 1986 in conjunction with group in 1979 three basically.These result of designs send the power transformation construction to make valuable contribution to guaranteeing gold utensil part quality, quickening 500kV.Yet, to compare with developed countries, no matter these gold utensils are from product material, structure, mechanical performance, or all there is larger gap in the aspect such as electric property.Along with the continuation of China reform and opening-up deeply and the further developing of power industry, the requirement of optimal design is more and more urgent.For this reason, we need to improve gold utensil strength of materials grade, simplify to connect, and improve the gold utensil reliability, and it is long to shorten string, reduces the tower head size.
Hardware is first parts that the gold utensil insulator string connects with cross arm of tower, namely is transitioned into dynamic interface property gold utensil from static state, stressed complexity, and not only itself is easily frayed, also will cause the damage of adjacent gold utensil.The hanging point structure of China's 500 kilovolt is still continued to use the hanging point form of 220 kilovolt at present, and namely tangent tower adopts the U-shaped link plate, and strain tower adopts the hanging wire veneer.Because the load of 500 kilovolt is large more than 4 times than 220 kilovolt, tower is generally higher, in running, because the External Force Acting such as icing, strong wind, ice-shedding and issuable wire noon are moving, the hanging wire node bears very high mechanical load, and the size and Orientation of these mechanical loads is often to change, when insulator string hanging wire node does not have between enough hinged performances or hinge axes and the shaft tower load-bearing component distance larger, on the node element or at vertical load gold utensil element, produce very large moment of flexure.This moment of flexure may cause shaft tower member or vertically load gold utensil damage.China's 500 kilovolts of large rooms line once causes the wearing and tearing of U-loop and ball-eye because of the hanging point dysplasia, ruptures and goes offline accident.The Soviet Union's 500 kilovolt are also once because of strain insulator-string hanging point unreasonable structure, when conductor galloping hanging point be connected gold utensil and destroy, cause nearly 100 kilometers wires to land, accident also appears in the hanging point of tangent tower.In the heavy ice line design, once tried out hinge type strain insulator hardware, this gold utensil both direction rotates not block flexibly and does not grind, and shortcoming is that weight is large, cost is high, processed complex.
Simultaneously because there is difference of height, and traditional thread gripping-board need to be bent to multiple inclination angle, need to and adjust the length that plate be regulated string by parallel link plate during hanging wire, specification requirement is high, installs also inconveniently, brings certain difficulty to the installer.
The utility model content
The technical problems to be solved in the utility model is: when hanging in order to solve traditional strain insulator string, cause need to be with the crooked multiple inclination angle of thread gripping-board because of difference of height, need to and adjust plate and regulate the sub-length specification requirement height of string by parallel link plate during hanging wire, inconvenient problem is installed, and the utility model provides a kind of supertension line system to solve the problems referred to above.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of supertension line system, comprise single hanging point duplex strain insulator string, described single hanging point duplex strain insulator string comprises hardware, the first U-loop, towing plate, the second U-loop, the first duplex plate that connects successively and is suspended on a pair of duplex strain insulator string at the first duplex plate two ends;
Described duplex strain insulator string comprises suspension insulator and the bigeminy board that is connected by socket-clevis eye with an end of suspension insulator, described bigeminy board comprises second duplex plate, be connected to all pressing shading ring and being connected to the first sub-section of string and the sub-section of the second string at the second duplex plate two ends of the second duplex plate middle part, the sub-section of described the first string comprises the first adjustment plate and the first strain clamp that connects successively by link, the sub-section of described the second string comprises the extending pull rod that connects successively by link, the right angle link plate, second adjusts plate and the second strain clamp, and the middle part of the second duplex plate in this duplex strain insulator string connects by bracing frame.
In order to reduce the link deformed damaged, described link is the oval ball bulb hanging ring.
More flexible in order to rotate, described hardware is the pivoting hardware.
The beneficial effects of the utility model are, the utility model supertension line system cooperates by pivoting hardware and U-loop, about can realizing, left-right rotation, do not need for adapting to the different discrepancy in elevation traditional thread gripping-board to be bent to multiple inclination angle convenient processing.After single hanging point hangs, do not need to answer the corner size and with the parallel link plate of different length with adjust the length that plate is adjusted two strings, this serial type hanging wire conveniently.
