Abstract
The utility model relates to a sulfur hexafluoride current transformer with a spherical shell, and the sulfur hexafluoride current transformer comprises a shell, a base, a ceramic bush, a shield ring, a primary wiring board, a second coil shield drum and a rupture disk. The sulfur hexafluoride current transformer is characterized in that the shell is spherical, and a flange seat is arranged outside the bottom of the spherical shell and is hermetically connected with the upper end of the ceramic bush. The shell is in a shape of a sphere of a symmetric structure, thus the sulfur hexafluoride current transformer disclosed by the utility model has the advantages of easiness in manufacturing, small windward area, stability and firmness, safety and convenience in use and transport, uniform distribution of inner and outer electric fields, good seal performance and improved use performance, ensures the reliability of inner and outer insulation of a transformer, and is of a seal connection structure of the flange seat and the ceramic sleeve.
Description
Technical field
The utility model relates to a kind of electric power mutual-inductor, particularly a kind of spherical shell sulfur hexafluoride current mutual inductor.
Background technology
The housing top of existing sulfur hexafluoride current mutual inductor is that hemisphere, bottom are that cylindrical shape, bottom are slab construction, and product is top-heavy, and the security performance in using, transporting is relatively poor.Because shell structure is asymmetric, causes inside and outside non-uniform electric, influences its serviceability.
Summary of the invention
The purpose of the utility model is in order to overcome above-mentioned weak point, and a kind of use, transportation safety, convenience are provided, and improves the spherical shell sulfur hexafluoride current mutual inductor of its serviceability.
The purpose of the utility model is achieved in that the spherical shell sulfur hexafluoride current mutual inductor comprises housing, base, insulator, shading ring, primary connection plate, secondary coil shielding cylinder, rupture disk; It is characterized in that housing is spherical; There is flange seat outside, spherical shell bottom, and flange seat and insulator upper end are tightly connected.
The utility model is owing to adopt above architecture advances, and housing is the sphere of symmetrical structure, and is easy to manufacture; Wind area is little, and is steady firm, use, transportation safety, convenience; Inside and outside Electric Field Distribution is even, guarantees the reliability of the inside and outside insulation of instrument transformer, adopts flange seat and the insulator structure that is tightly connected; Good seal performance has improved its serviceability.
