Abstract
The utility model provides a novel separate equalizing ring for six linked strain insulator-strings with compact and flexible structure, convenient usage and installation and excellent performance, which consists of six section rings, namely upper and lower edge rings A, upper and lower edge rings B and upper and lower middle rings which are combined into a ring shape, insulation connecting pieces are arranged respectively on every section ring of the upper and lower edge rings A, the upper and lower edge rings B and the upper and lower middle rings, and the upper and lower edge rings A, the upper and lower edge rings B and the upper and lower middle rings all made of high-strength high quality aluminum alloy; the utility model with separate type has the advantages of reliable connection, compact and reliable structure and reduced weight of the ring, and provides convenience for production, construction and installation, and can meet the long-term use requirements of power transmission line.
Description
Technical field
The utility model relates to a kind of electric armour clamp, especially relates to a kind of overhead transmission line grading ring.
Background technology
The effect of grading ring is exactly the corona of controlling on the insulator, and corona is exactly when the voltage on lead and the gold utensil is very high, and its surperficial electric potential gradient has surpassed critical value, just produces visual corona.Because its surperficial air produces ionization under too high electric potential gradient, send blue radiance, sound is arranged simultaneously, corona discharge phenomenon that Here it is.The harm of corona mainly shows the consumption of the energy.
At present, general grading ring is the ring body of a closure, is installing, when changing, line need passed annular distance, install again, in some occasions that need install additional and change, circuit need be cut off, install grading ring after, again circuit is connected, cause workload big, also need other auxiliary gold utensils, cost also increases.
Summary of the invention
The purpose of this utility model provides the novel split type six strain insulator-string grading rings that a kind of compact conformation is flexible, use simple installation, superior performance.
The utility model adopts following technical scheme:
Split type six strain insulator-string grading rings of the present utility model, by side ring A up and down, up and down side ring B and up and down in ring totally six sections ring combinations surround ring-type, described side ring A up and down, up and down side ring B and up and down in be respectively arranged with link on every section ring of ring.
Up and down side ring A of the present utility model, up and down side ring B and up and down in ring all adopt aluminium alloy.
Compared with prior art, the utlity model has following advantage:
1, split type six strain insulator-strings of the utility model are mainly combined by side ring A, side ring B, middle ring and link with grading ring, and its structure adopts split type, connect reliably, and compact conformation is flexible.
2, split type six strain insulator-strings of the utility model are made up of six sections rings respectively with grading ring, alleviate the weight of ring, provide convenience for producing, constructing, and use simple installation, can satisfy the long-term instructions for use of transmission line.
3. the utility model adopts high strength fine aluminum alloy, has anti-corrosive properties, non-corrosive, and striking is satisfactory for result, and discharge time is short.

Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
As shown in Figure 1 and Figure 2, split type six strain insulator-string grading rings of the present utility model, by side ring A1 up and down, up and down side ring B2 and up and down in ring 3 totally six sections ring combinations surround ring-type, described side ring A1 up and down, up and down side ring B2 and up and down in be welded with link respectively on every section ring in the ring 3.
Up and down side ring A1, up and down side ring B2, up and down in ring 3 all adopt high strength fine aluminum alloy.
Be the schematic diagram of side ring of the present utility model and middle ring as shown in Figure 3, Figure 4, link mainly is made up of link and fastening bolt.
As Fig. 5, shown in Figure 6, this split type grading ring is used for six strain insulator-strings, its up and down side ring A1, up and down side ring B2 and up and down in 3 six sections rings of ring be installed in respectively on six strain insulator-strings, this structure adopts split type, easy for installation, connects reliable.
The utility model is for guaranteeing the fineness of contact-making surface, satisfy the anticorona requirement of circuit, each section surface at grading ring all passes through fine finishining, at first, on bending machine, before the bend pipe, aluminum tube surfaces is brushed one deck machine oil, when bending aluminum pipe, each curved camber is tried one's best littler, guarantees that bending the pipe that is not elliptical tube, and smooth surface does not have concavo-convex phenomenon; Secondly, the connecting portion of each section grading ring surface, insulated connecting piece carefully rubs with fine sandpaper, with charcoal repeatedly friction is carried out at these positions in case of necessity, makes the fineness on grading ring surface reach requirement.
These six strain insulator-strings adopt split type with grading ring.Guarantee the anticorona requirement of circuit, successfully use Zhoushan of national first high tower, span maximum and continent to network in the big overhead crossing engineering, this project mainly distributes across the sea.Crossover tower is the highest reaches 370m, the crossing span maximum reach 2756m, these two technical data be overhead crossing engineering.
