Abstract
The utility model discloses a shield cover for connecting cable terminal and link fitting, including the shield cover body of circle cover column structure, the material of shield cover body is semiconduction silicon rubber, and shield cover body internal diameter is less than the insulator external diameter at cable terminal and the external diameter of link fitting. The shielding cover in the utility model adopts semi-conductive silicon rubber material, which not only has elasticity, but also has good sealing performance and heat resistance; can improve electrical performance and adjust electric field distribution without local concentration of field intensity.
Description
Technical Field
The utility model relates to an electric power field especially relates to a shield cover for connecting cable termination and link fitting.
Background
The reliability of the high voltage cable accessory can be judged from the aspects of electrical performance, sealing moisture resistance, mechanical performance, process performance and the like. Nowadays, an insulating tape, a semi-conductive tape, a waterproof tape, a fireproof tape, and the like are used as a wrapping tape in the installation of a cable terminal. However, a plurality of problems exist during wrapping, firstly, the requirement on the wrapping process is high in the installation process, and different tapes have different wrapping process requirements; when a sealing strip needs to be wrapped between the insulated end part of the cable and the wiring hardware fitting, in order to ensure the sealing effect, the insulated end part is usually cut into a cone so as to ensure that the wrapped sealing strip can be well adhered with the insulation, and the time required for pinning into the cone is longer; in addition, because the wrapping tape is arranged inside the cable, once the installation problem occurs, the wrapping tape is difficult to find in time, so that potential safety hazards are easily caused by using the wrapping tape.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a shield cover for connecting cable termination and link fitting.
In order to realize the purpose of the utility model, the technical proposal of the utility model is that: the utility model provides a shield cover for connecting cable terminal and link fitting, includes the shield cover body of circle cover column structure, and the material of shield cover body is semi-conductive silicon rubber, and the shield cover body internal diameter is less than the insulator external diameter at cable terminal and link fitting's external diameter. The semiconductive silicon rubber has elasticity and can eliminate static electricity.
Furthermore, a circle of annular notch is formed in the inner ring of the end part of the shielding case body at one end of the cable terminal. The annular notch of a circle accords with the requirement of electric field intensity evenly distributed, relies on the geometric curve to improve electric field distortion, and electric stress control unit stable performance.
The utility model has the advantages that:
1. the shielding cover in the utility model adopts semi-conductive silicon rubber material, which not only has elasticity, but also has good sealing performance and heat resistance; can improve electrical performance and adjust electric field distribution without local concentration of field intensity.
2. The utility model discloses in can get rid of and cut this process of "pencil stub" in the cable termination installation procedure, improve the installation effectiveness.
3. The utility model provides a shield cover can replace semi-conductive area, insulating tape, waterproof tape and fire prevention area etc. completely, has saved the time around the package strip, has reduced the installation degree of difficulty and has avoided the potential safety hazard problem that appears in the package strip.
