Abstract
The invention discloses a carbon fiber voltage transformer and belongs to the technical field of transformers. The carbon fiber voltage transformer comprises a terminal block, a grading shield, an insulating sheath, a fixing flange, a primary winding, a second winding, a shielding case, a secondary terminal box and an iron core. The outside of a primary lead shielding tube is provided with a capacitive type main insulator wrapped by organic composite plastic tapes; the internal space of an outer case is filled with insulating grease serving as insulating medium; the first lead shielding tube is a rigid tube; the turn ratio between the primary winding and the secondary winding is 10:9.
Description
technical field
The present invention relates to carbon fiber voltage transformer, belong to instrument transformer technical field.
Background technology
At present, market mainly contains the carbon fiber voltage transformer of three kinds of structures, one is oil-immersed electromagnetic formula carbon fiber voltage transformer, and the main insulation medium of this carbon fiber voltage transformer is oil and paper, and Main Insulation Structure of Electric can be Cascade, also can be capacitor type; The second is sulfur hexafluoride gas-insulating electromagnetic type carbon fiber voltage transformer, and main insulation medium is sulfur hexafluoride gas, and Main Insulation Structure of Electric can be by grading shield uniform electric field, also can be that capacitor type coordinates grading shield uniform electric field; The third is immersion capacitive type carbon fiber voltage transformer, and main insulation medium is oil and film, and Main Insulation Structure of Electric is capacitance-voltage-distributing type.
There is following shortcoming in above carbon fiber voltage transformer:
1. oil-immersed electromagnetic formula carbon fiber voltage transformer and immersion capacitive type carbon fiber voltage transformer are because main insulation medium all employ oil, cause product office to be amplified, and dielectric loss is large, easily cause the seepage of oil, contaminated environment simultaneously.
2. sulfur hexafluoride gas-insulating electromagnetic type carbon fiber voltage transformer manufacturing cost is higher, and insulation property are unreliable, and the leakage of sulfur hexafluoride gas can cause environmental pollution.
Summary of the invention
The present invention is directed to the proposition of above problem, and develop carbon fiber voltage transformer.
The object of this invention is to provide reliable, the free of contamination dry type carbon fiber voltage transformer for 35kV and above of a kind of insulation property.
The object of the present invention is achieved like this, is fixed on by iron core on shell body, and one time winding, secondary winding are wound on iron core column, and one time winding overcoat has cylindrical metal radome; Secondary winding lead-in wire is drawn by secondary terminal box, and one time cymbals group is connected with binding post by the shielded-plate tube that once goes between; We pack capacitor type main insulation at the organic combined insulated plastic tape of shielded-plate tube external application that once goes between; The flange of fixed capacity type main insulation is connected with shell body, within the outer shell clearance spaces be full of insulation ointment make dielectric; Pack in the capacitor type main insulation on shielded-plate tube that once goes between outer with insulating sleeve; The shielded-plate tube that once goes between can be rigid pipe.Binding post, grading shield, insulating sleeve, mounting flange, winding, secondary winding, radome, secondary terminal box, an iron core are made up of carbon fiber
The present invention has following advantage:
1. product is dry type carbon fiber voltage transformer, and insulation property are reliable, without oil, without gas, avoids seepage, contaminated environment, substantially non-maintaining;
2. cost of goods manufactured is lower, is easy to promote.
Accompanying drawing explanation
Fig. 1 is the generalized section of a kind of structure of the present invention.
Embodiment
Winding 9, a secondary winding 10 are wound on the stem of unshakable in one's determination 13, one time winding 9 overcoat has cylindrical metal radome 11; Unshakable in one's determination 13 are fixed on shell body 7, and the lead-in wire of secondary winding 10 is drawn by secondary terminal box 12, and one time winding 9 is connected with binding post 1 by the shielded-plate tube 3 that once goes between; Grading shield 2 is fixed on and once goes between on shielded-plate tube 3, and once going between, the organic combined insulated plastic tape of shielded-plate tube 3 external application packs capacitor type main insulation 4; The flange 6 of fixed capacity type main insulation 4 is connected with shell body 7, is full of insulation ointment 8 makes dielectric in the inside clearance spaces of shell body 7; Pack in the capacitor type main insulation 4 on shielded-plate tube 3 that once goes between outer with insulating sleeve 5; The shielded-plate tube 3 that once goes between can be rigid pipe.One time winding (9) is 10 to 9 with the turn ratio of secondary winding (10).
The above; be only the present invention's preferably embodiment; but protection scope of the present invention is not limited thereto; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to according to technical scheme of the present invention and inventive concept thereof and replace or change, all should be encompassed within protection scope of the present invention.
