Description

10KV European stress cone

Technical Field

The utility model relates to the technical field of high-voltage transmission lines, in particular to a 10KV European stress cone.

Background

In the existing stage of 10KV stress cone necking design, when workers are installed, the stress cones are not tied tightly, when the stress cones are inserted into the front connectors, the stress cones can move and run on the cables, so that the installation is not standard, and in the later stage, semi-conductive parts of the stress cones are easy to discharge in the using process, so that the cables are broken down.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a 10KV European stress cone aiming at the defects of the prior art, so that accurate installation among all accessories is ensured, and the safety performance is improved.

In order to achieve the purpose, the utility model adopts the following technical scheme:

the utility model provides a 10KV European-style stress cone which comprises an upper stress cone part and a lower stress cone part, wherein one end of the upper stress cone part is butted with one end of the lower stress cone part;

and a stress frustum is arranged at one end of the upper part of the stress cone, which is separated from the lower part of the stress cone.

Furthermore, the stress frustum is annular, and the outer circumference of the stress frustum is connected with a stress frustum wall.

Further, the stress frustum and the stress frustum wall are integrally formed.

Furthermore, the middle part of the upper part of the stress cone is hollow, and the middle part of the lower part of the stress cone is hollow; the upper part of the stress cone and the lower part of the stress cone are coaxially butted.

Further, the diameter of the upper part of the stress cone is the same as the diameter of the lower part of the stress cone.

Furthermore, the pipe wall of the end, adjacent to the lower part of the stress cone, of the upper part of the stress cone is in an outer convex arc shape, and the pipe wall of the end, adjacent to the upper part of the stress cone, of the lower part of the stress cone is in an inner concave arc shape.

Further, the outer convex arc is butted with the inner concave arc.

The utility model has the beneficial effects that: this open step of european style stress cone relates to, and the workman is when the installation, and the spacing step of semi-conductive area is docked with the stress frustum of stress cone, and the spacing step of stress cone with the semi-conductive area withstands, and the position can not run to the stress cone, has guaranteed the accuracy of each accessory mounted position, has guaranteed the security performance of product.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and are not intended to limit the utility model.

Referring to fig. 1, a 10KV european style stress cone includes a stress cone upper portion 1 and a stress cone lower portion 2, wherein one end of the stress cone upper portion 1 is butted with one end of the stress cone lower portion 2;

and a stress frustum 3 is arranged at one end of the upper stress cone part 1, which is separated from the lower stress cone part 2.

Referring to fig. 3, the stress frustum 3 is a circular ring, and a stress frustum wall 301 is connected to an outer circumference of the stress frustum 3.

The stress cone 3 and the stress cone wall 301 are integrally formed.

When the cable is installed, the semi-conductive belt is firstly wound on a limit step at a corresponding position of the cable, the stress cone 3 serves as a stop step, when the stress cone is installed on the cable, the stress cone 3 of the stress cone is pushed to the step wound by the semi-conductive belt, the stress cone is propped against the step wound by the semi-conductive belt, and when the stress cone is inserted into the inner surface of the front connector, the stress cone cannot run, so that the accuracy of installation positions of various accessories is guaranteed, and the safe operation of products is guaranteed.

Referring to fig. 2 and fig. 1, the middle of the upper part 1 of the stress cone is hollow, and the middle of the lower part 2 of the stress cone is hollow; the stress cone upper part 1 and the stress cone lower part 2 are coaxially butted.

The diameter of the stress cone upper part 1 is the same as the diameter of the stress cone lower part 2.

Referring to fig. 1, a pipe wall at an end of the stress cone upper portion 1 adjacent to the stress cone lower portion 2 is an outward convex arc 101, and a pipe wall at an end of the stress cone lower portion 2 adjacent to the stress cone upper portion 1 is an inward concave arc 201.

The outer convex arc 101 is butted with the inner concave arc 201.

The convex arc 101 and the concave arc 201 are butted, so that an electric field can be uniform, and stress can be dispersed.

The above-mentioned embodiments only express the embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
