Abstract
The utility model relates to power equipment, in particular to an equalizing ring which comprises a ring body and a connecting link for connecting the ring body and flanges. The utility model is characterized in that the connecting link is a tube or a bar. The connecting link is changed to the tube or the bar in the utility model, the strength of the connecting link is increased, and the problem of shake of the equalizing ring is effectively solved; thereby, the problems of crackles at the connecting place of an insulator and the equalizing ring, and the unstable connection caused by the shake of the equalizing ring are solved. The utility model has the characteristic of high practicability.
Description
Technical field
The utility model relates to power equipment, particularly grading ring.
Background technology
The insulator of supergrid all is furnished with this annex of grading ring mostly, improves the Electric Field Distribution of insulator, avoids bloom, the deterioration of insulator, plays the effect of protection insulator.But because the support of grading ring is thiner, grading ring is easy to generate chatter during use, long-term chatter causes insulator and grading ring junction crackle to occur, thereby cause the fracture of grading ring connecting rod, it is not firm that the while chatter causes the grading ring connecting rod to be connected with lead, can't play the effect of the Electric Field Distribution of improving insulator effectively, in case cause unplanned power failure, its harm is not only economic loss, and social influence is important and far-reaching especially.
Summary of the invention
The purpose of this utility model is to overcome the defective that prior art exists, and a kind of grading ring that can effectively avoid chatter is provided.
For achieving the above object, the technical solution of the utility model is: a kind of grading ring, comprise ring body and the connecting rod that ring body is linked to each other with flange, and it is characterized in that connecting rod is tubing or bar.
The cross section of aforementioned tubes or bar is round.
The cross section of aforementioned tubes or bar is square.
The utility model is changed into tubing or bar with connecting rod, increased the intensity of connecting rod, can effectively solve the chatter problem of grading ring, with regard to having solved, have practical characteristics like this because the chatter of grading ring causes insulator and grading ring junction crackle to occur and is connected not firm problem.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Accompanying drawing 2 is the vertical view of the utility model accompanying drawing 1.
Embodiment
As shown in Figure 1, 2, between the flange 3 and ring body 1 of grading ring, adopt tubulose or club-shaped material, as aluminum pipe or aluminium bar, its cross section can be adopted circular or square.
Claims (3)
1, a kind of grading ring comprises ring body and the connecting rod that ring body is linked to each other with flange, it is characterized in that connecting rod (2) is tubing or bar.
2, grading ring according to claim 1, the cross section that it is characterized in that aforementioned tubes or bar is round.
3, grading ring according to claim 1, the cross section that it is characterized in that aforementioned tubes or bar is square.
