Abstract
The utility model discloses a current transformer with a ring-shaped metal sleeve, which comprises an insulating bracing column, wherein a current transformer is arranged on the upper end of the insulating bracing column and a metal sleeve which forms a ring-shaped galvanic circle is arranged inside the current transformer. The current transformer has rational structure and adopts the metal sleeve which forms the ring-shaped galvanic circle, the heat dissipation performance is good, the electric field distribution is good, and the local discharge is low.
Description
Technical field:
The utility model relates to a kind of current transformer.
Background technology:
Existing current transformer office amplifies, non-uniform electric, and thermal diffusivity is not good enough.
Summary of the invention:
It is a kind of rational in infrastructure that the purpose of this utility model is to provide, the current transformer of the tool endless metal cover of favorable working performance.
Technical solution of the present utility model is:
A kind of current transformer of tool endless metal cover comprises that insulation support column, insulation support column upper end are provided with current transformer, is characterized in that: the metallic sheath that forms annular galvanic circle is set in the current transformer inboard.
The edge support column is integrated form with the insulation support column.
Current transformer has earthing screen device, earthing screen device comprises the metal supporting plate of placing iron core, line bag, the metal supporting plate is connected with metal circular tube, and metal circular tube stretches into the lower end of insulation support column, and is connected with the ground connection secondary line at the lower end part of insulation support column.
The insulation support column adopts the large distance form, and the spacing between the adjacent full skirt is 40～50mm.
The present invention is rational in infrastructure, adopts the metallic sheath that forms annular galvanic circle, makes thermal diffusivity good, and Electric Field Distribution is good, and office lowers; Adopt and support and the integrated form of instrument transformer, rational in infrastructure, compactness, easy to use; Adopt unique earth shield structure, Electric Field Distribution is even, good working effect; Adopt the large distance form, do not tie condensation.
