Abstract
The invention discloses an epoxy resin pouring type voltage transformer which belongs to the technical field of voltage transformers. The voltage transformer comprises a primary terminal (1), an equalizing ring (2), a shielding ring (3), a winding (4), an iron core (5), an epoxy resin shell (6), a secondary connecting terminal (7) and a mounting channel steel (8). The epoxy resin pouring type voltage transformer has the advantages of favorable insulating property, simple and feasible structure, strong part workability, convenience of assembly, lowered production cost, reliable service ability and the like.
Description
Technical field
The invention belongs to the voltage transformer technical field, belong to a kind of poured with epoxy resin formula voltage transformer in particular.
Background technology
At the voltage transformer of the above grade of China 66kV, the overwhelming majority is directly with out of doors and be installed in outdoor substation.Present most voltage transformer is porcelain insulating, oil immersed type structure, exists the hidden danger of blast.
Summary of the invention
The present invention has proposed a kind of poured with epoxy resin formula voltage transformer in order to overcome the above problems.
A kind of poured with epoxy resin formula voltage transformer of the present invention comprises primary connection post, grading ring, shading ring, winding, iron core, epoxy resin housing, secondary connection terminal, channel-section steel is installed; Wherein: described epoxy resin housing comprises a hydrostatic column and a base, and the hydrostatic column of described epoxy resin housing and base are the overall structures of being cast by epoxy resin; A pair of installation channel-section steel is arranged below the base of described epoxy resin housing; The inside of described epoxy resin housing hydrostatic column is equipped with primary connection post, grading ring, shading ring, winding, iron core; Described primary connection post is positioned at the top of epoxy resin housing hydrostatic column; The root of described primary connection post links to each other with grading ring; Described shading ring edge is enclosed within on the inner chamber of epoxy resin housing hydrostatic column; Described winding is installed in the shading ring inside of epoxy resin housing inner chamber.
This instrument transformer is totally-enclosed, single stage type, semi-insulating structure.Removing primary connection post root has grading ring, evenly the end electric field.Shading ring shields whole winding; The high-quality silicon steel sheet that adopts unshakable in one's determination, no-load current is little; Except that a secondary connection terminal, whole device body uses outdoor poured with epoxy resin; The secondary connection place has special-purpose secondary connection terminal; The installation channel-section steel is arranged at the instrument transformer bottom; For the pollution flashover and the wet flashover level that improve instrument transformer, the instrument transformer part surface has big or small full skirt.
Instrument transformer of the present invention has been stopped oily infrastructure product owing to the problem that may occur in the operation maintenance such as not strict oil seepage that causes of quality control and oil quality deterioration.The present invention is compared with prior art: have that insulation property are good, simple for structure, the parts processability is strong, easy to assembly, reduced advantages such as production cost, reliable working performance.
