Abstract
The utility model discloses a kind of double bundle conductor composite insulator tension string, it comprises connection tower U-shaped link (1), extends ring (2), U-shaped link (3), yoke plate (4), be divided into two again, often join connect by ring-ring 2 pairs of inner arc U-loops (5), ball-eye (6), bulb socket arrangement composite insulator (7), socket-clevis eye (8) composition, then be combined into 1 string by yoke plate (9), be then followed successively by 2 pairs of inner arc U-loops (5) that ring-ring connects, adjustment plate (10), U-shaped link (11) and reinforced strain clamp (12).The utility model is by changing the connected mode between gold utensil, enable strain insulator-string ± 10 ~ 20 ° ground axial rotation, thus avoid bulb socket arrangement composite insulator to occur axially to be turned round in circuit hurricane situation, destroy the mechanical strength of plug and its end metal fitting.Composite insulator keeps bulb, socket arrangement, therefore, and still can charged for replacement composite insulator.
Description
Technical field:
The utility model relates to a kind of 110 ~ 220kV overhead transmission line double bundle conductor composite insulator tension string, belongs to the design of electric power system overhead transmission line, operation, maintenance field.
Background technology:
So far, the composite insulator tension string standard material of State Grid Corporation of China's competitive bidding is conventional type, and the syndeton of insulator string cannot make composite insulator axial rotation; At present, usually take the way of the strength grade improving composite insulator, successively change 100kN or 120kN into by 70kN changes 160kN into the specified mechanical load of such as standard material composite insulator.
Tsing-Hua University within 2002, carried out composite insulator ± research of 10 ° of tension-torsion dynamic loading experiments, think that inner inlaying type composite insulator can meet service requirement under various dynamic loads.(#1 ~ #15 is compression joint type to one group of 500kV Anti-tension composite insulator that Shandong Research Inst. of Electric Power carries out for 2005, #16 ~ #27 is inner inlaying type) ± 10 ° of tension-torsion pull and torsion test data show: test product mechanical damage after stretch-twisting combination test that end connects for compression joint type has reduction in various degree (on average reducing by 5%), and inner inlaying type test product mechanical failure load after stretch-twisting combination test raises (on average improving 6%) on the contrary.This is because the mechanical load of compression joint type test product is a process declined gradually, and inner inlaying type test product is carved the pulling force born block both sides and redistributed after stretch-twisting combination test, and mechanical failure load comparatively initial value wants high.Because inner inlaying type manufacture craft is not bery ripe, so far, mostly select crimp connection type composite insulator.And minimizing even avoids composite insulator axis to be the key realizing life-cycle theory by turning round.
Utility model content:
The purpose of this utility model is to overcome the deficiency of above-mentioned prior art and provides one to impel wire icing even, reduces conductor galloping amplitude; Reduce mechanical load even brittle failure phenomenon, reach life cycle management, double bundle conductor composite insulator tension string safe and reliable to operation.
The purpose of this utility model can be reached by following measure: a kind of anti-dance type double bundle conductor composite insulator tension string, it is characterized in that it comprises connection tower inner arc U-loop, connection tower inner arc U-loop connects prolongation ring, extend ring and connect U-shaped link, U-shaped link connects yoke plate, the two ends of yoke plate connect the inner arc U-loop that 2 pairs of ring-rings connect respectively, often pay the inner arc U-loop that ring-ring connects and all connect a ball-eye, often pay ball-eye and all connect a socket arrangement composite insulator, often prop up socket arrangement composite insulator and all connect a socket-clevis eye, socket-clevis eye is connected to the two ends of yoke plate, the two ends of yoke plate connect the inner arc U-loop that 2 pairs of ring-rings connect respectively, often pay the inner arc U-loop that ring-ring connects and all connect an adjustment plate, often pay adjustment plate and all connect a U-shaped link, often pay U-shaped link and all connect a reinforced strain clamp.
In order to realize the purpose of this utility model further, the described two ends of often propping up socket arrangement composite insulator are equipped with bird-proof cover type grading ring.
The utility model can produce following good effect compared with the prior art: the utility model one designs at live end two inner arc U-loops that 2 pairs of ring-rings connect, decrease the torsional rigidity of double bundle conductor, impel wire icing even, reduce conductor galloping amplitude; Two is two inner arc U-loops that the earth terminal end of composite insulator is connected with 2 pairs of ring-rings and connects, and can solve composite electric insulator core bar and be turned round, reduces mechanical load even brittle failure phenomenon, reach life cycle management design concept; ; Three is that composite insulator keeps bulb, socket arrangement, therefore, and still can charged for replacement composite insulator.The utility model is by changing the connected mode between gold utensil, enable strain insulator-string ± 10 ~ 20 ° ground axial rotation, thus avoid bulb socket arrangement composite insulator to occur axially to be turned round in circuit hurricane situation, destroy the mechanical strength of plug and its end metal fitting.Composite insulator keeps bulb, socket arrangement, therefore, and still can charged for replacement composite insulator.
