Abstract
The utility model discloses a saddle-shaped pressure equalizing ring, which comprises a ring body and a bracket, wherein the ring body is saddle shaped, the ring body is fixedly connected with the bracket, the bracket is fixed inside the lower portion of the ring body, the lower end of the bracket is fixed on a yoke plate of a V-shaped suspension string through bolts, and a portion, close to the ring body, of the V-shaped suspension string is vertical to the ring body. The saddle-shaped pressure equalizing ring of the utility model is suitable for the V-shaped suspension string, and the saddle-shaped pressure equalizing ring is connected with the yoke plate through the bolts, is convenient and practical, and good in service performance.
Description
Technical field
The utility model relates to power line construction equipment technical field, particularly a kind of saddle-shape grading ring.
Background technology
At present, in extra high voltage network, V-type suspension string is just more and more applied.Conventional V-type suspension string adopts double strap, and this structural shape cannot guarantee that every insulator string center line is vertical with ring body plane, often self bloom of grading ring ring body, support, and often there is the problem that insulator and grading ring ring body are collided.
Utility model content
The utility model technical issues that need to address are grading ring self blooms, and insulator and grading ring ring body are collided, insulator center line and ring body plane out of plumb.
For solving the problems of the technologies described above, the utility model provides a kind of saddle-shape grading ring, comprise ring body and support, described ring body is the shape of a saddle, described ring body is fixedly connected with support, and described support is fixed on the inner side, below of described ring body, and described support lower end is bolted on the yoke plate in V-type suspension string, and described V-type suspension string is vertical with described ring body near the part of described ring body.In transmission line, V-type suspension string adopts saddle-shape grading ring, can guarantee that every insulator string center line is vertical with ring body plane and can avoid insulator and grading ring ring body to collide, convenient and practical, serviceability is good, easy construction, clear and definite grading ring support and ring body bond pad locations, be positioned at inside ring body, within grading ring ring body shield ranges solder joint.
As optimal technical scheme of the present utility model, the endless tube diameter of described ring body is 90-110mm, is preferably 100mm.Strengthened ring body size, external diameter changes Φ 100 into by Φ 80.It is that ring is centered close in the middle of 2～3 insulators of described V-type suspension string that the cover of described ring body enters the degree of depth.The cover that has strengthened grading ring enters the degree of depth, covers the degree of depth and is centered close to and is changed into ring in the middle of 1～2 insulator and be centered close in the middle of 2～3 insulators by ring.The bending radius at the endless tube center of described ring body is 380-420mm, is preferably 400mm.Determine that endless tube center curvature radius is R400, R400 endless tube bending radius is conducive to grading ring body and is shaped, and has avoided the bending of endless tube wrinkling, thereby has prevented grading ring self bloom.
As further improvement of the utility model, described support is inwardly received from top to bottom, and the part that the lower end of described support is connected with described yoke plate is stretched out described ring body.Strengthen stent size, thereby grading ring support and ring body bonding area are increased, guarantee bonding strength, needn't strengthen weld strength by bending rack, avoid sweep bloom, sweep is Artificial Control, likely exceed ring body shield ranges, suitably inner supporting rack bending position strengthens bending radius simultaneously, avoids the bloom of support crooked position.
Saddle-shape grading ring of the present utility model, construction easily, is applicable to V-type suspension string, has good all pressures shield effectiveness, can guarantee transmission line safe and stable operation.

Embodiment
Describe optimal technical scheme of the present utility model in detail below in conjunction with accompanying drawing.
As shown in the figure, a kind of saddle-shape grading ring of the present utility model, comprise ring body 1 and support 2, described ring body 1 is the shape of a saddle, described ring body 1 is fixedly connected with support 2, and described support 2 is fixed on the inner side, below of described ring body 1, described support 2 lower ends are bolted on the yoke plate 4 in V-type suspension string 3, and described V-type suspension string 3 is vertical with described ring body 1 near the part of described ring body 1, the endless tube diameter of wherein said ring body is 100mm, it is that ring is centered close in the middle of 2～3 insulators of described V-type suspension string that the cover of described ring body enters the degree of depth, the bending radius at the endless tube center of described ring body is 400mm, described support 2 is inwardly received from top to bottom, and the part that the lower end of described support 2 is connected with described yoke plate 4 is stretched out described ring body 1.
In transmission line, V-type suspension string adopts saddle-shape grading ring, can guarantee that every insulator string center line is vertical with ring body plane and can avoid insulator and grading ring ring body to collide, convenient and practical, serviceability is good, easy construction, clear and definite grading ring support and ring body bond pad locations, be positioned at inside ring body, within grading ring ring body shield ranges solder joint.
Strengthened ring body size, external diameter changes Φ 100 into by Φ 80.The cover that has strengthened grading ring enters the degree of depth, covers the degree of depth and is centered close to and is changed into ring in the middle of 1～2 insulator and be centered close in the middle of 2～3 insulators by ring.Determine that endless tube center curvature radius is R400, R400 endless tube bending radius is conducive to grading ring body and is shaped, and has avoided the bending of endless tube wrinkling, thereby has prevented grading ring self bloom.
Strengthen stent size, thereby grading ring support and ring body bonding area are increased, guarantee bonding strength, needn't strengthen weld strength by bending rack, avoid sweep bloom, sweep is Artificial Control, likely exceed ring body shield ranges, suitably inner supporting rack bending position strengthens bending radius simultaneously, avoids the bloom of support crooked position.
Saddle-shape grading ring of the present utility model, ring body and support are by being welded and fixed.
Saddle-shape grading ring of the present utility model, is applicable to V-type suspension string, and construction easily, has good all pressures shield effectiveness, can guarantee transmission line safe and stable operation.
Saddle-shape grading ring of the present utility model, is applicable to V-type suspension string, and saddle-shape grading ring is connected with yoke plate by bolt, convenient and practical, and serviceability is good.
