Abstract

The invention discloses an internal shield ring of a shield sleeve used for a switch cabinet. The internal shield ring comprises an electric conduction nylon ring, the wall of the electric conduction nylon ring is covered with small holes, one end of a high-voltage lead is embedded into the wall of the electric conduction nylon ring, and the upper end and the lower end of the electric conduction nylon ring are in a circular arc shape with flat end faces. The internal shield ring is reasonable in structure; by the adoption of the electric conduction nylon ring, the internal shield ring is light in weight; because the upper end and the lower end of the electric conduction nylon ring are in the circular arc shape with the flat end faces, no partial discharge exists under standard test voltage, and working performance is guaranteed.

Description

The internal shield ring of switch cubicle shielded tube
Technical field
The present invention relates to a kind of internal shield ring of switch cubicle shielded tube.
Background technology
Existing switch cubicle shielded tube has inside and outside shielding ring, and internal shield ring generally adopts woven wire form, the upper and lower side indentation of woven wire, and the office of causing amplifies, and affects serviceability.
Summary of the invention
The object of the present invention is to provide a kind of rational in infrastructure, the internal shield ring of the switch cubicle shielded tube that serviceability is good.
Technical solution of the present invention is:
An internal shield ring for switch cubicle shielded tube, is characterized in that: comprise electroconductive nylon circle, and electroconductive nylon circle wall is covered with aperture, and one end of high-voltage connection is embedded in electroconductive nylon circle wall, and the upper and lower end of electroconductive nylon circle is smooth circular of end face.
The upper and lower end of electroconductive nylon circle is that end face is smooth, periphery protrudes from the circular of electroconductive nylon circle wall.
The muscle shape played the role of positioning is set at electroconductive nylon circle wall inner surface protruding.
The present invention is rational in infrastructure, adopts electroconductive nylon circle, light weight, and upper and lower end is smooth circular of end face, puts, ensure that service behaviour under code test voltage without office.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the invention will be further described.
Fig. 1 is the structural representation of one embodiment of the invention.
Embodiment
An internal shield ring for switch cubicle shielded tube, comprises electroconductive nylon circle 1, and electroconductive nylon circle wall is covered with aperture 2, and one end of high-voltage connection 3 is embedded in electroconductive nylon circle wall, and the upper and lower end of electroconductive nylon circle is end face 4,5 smooth circular.
The upper and lower end of electroconductive nylon circle is that end face is smooth, periphery protrudes from the circular of electroconductive nylon circle wall, makes service behaviour better, and has the positioning action be entrenched in union body.
The muscle shape projection 6 being entrenched in positioning action in union body has been set at electroconductive nylon circle wall inner surface.
