The major insulation structure comprises a low voltage coil, a high voltage coil, an internal layer insulating paper cylinder, an external layer insulating paper cylinder and an iron core; the low voltage coil is wound at the outside of the internal layer insulating paper cylinder, the high voltage coil is wound at the outside of the external layer insulating paper cylinder, a set of small insulating paper cylinders are arranged between the internal layer insulating paper cylinder and the external layer insulating paper cylinder, and uniformly arranged in a space formed by the internal layer insulating paper cylinder and the external layer insulating paper cylinder. The internal layer insulating paper cylinder and the external layer insulating paper cylinder are supported by a set of small insulating paper cylinders to form a whole body. The major insulation structure of the high-frequency and high-voltage dedusting transformer has high electrical performance, both the capacitance and the dielectric loss meet requirements of the dedusting transformer, the heat dissipation conditions of the high-frequency and high-voltage dedusting transformer are improved, and the high voltage coil and the low voltage coil are reliably supported. The major insulation structure of the high-frequency and high-voltage dedusting transformer is in particular applicable to a dedusting transformer with 60kV voltage class and 7-8kHz working frequency.
Description
Technical field
The present invention relates to a kind of transformer, specifically a kind of high-frequency high-voltage dust removing transformer.
Background technology
Transformer is mainly by low-voltage coil, high-tension coil and unshakable in one's determination the composition, and the coil that is wound with on iron core once with secondary is used as low-voltage coil and high-tension coil.Based on the high magnetic conductivity of iron material, most magnetic flux is confined in the iron core, and therefore, two groups of coils can obtain the magnetic coupling of suitable high level by this.
Two insulating cylinder structures that the main insulation of the power transformer of the general 60kV electric pressure of existing dust removing transformer is made up of interior insulating cylinder and external insulation tube adopt corrugated board to support as insulation between interior insulating cylinder and external insulation tube.60kV electric pressure operating frequency is after the dust removing transformer of 7～8kHz adopts above-mentioned Main Insulation Structure of Electric, and its electric capacity and dielectric loss all can not satisfy the requirement of dust removing transformer.
Summary of the invention
In order to overcome the shortcoming of existing dust removing transformer Main Insulation Structure of Electric, the purpose of this invention is to provide a kind of high-frequency high-voltage dust removing transformer, the electric property of this high-frequency high-voltage dust removing transformer is greatly improved, and electric capacity and dielectric loss have all satisfied the requirement of dust removing transformer; And the radiating condition of this high-frequency high-voltage dust removing transformer improves, and the high and low pressure coil obtains more reliable support.
The objective of the invention is to be achieved through the following technical solutions:
A kind of high-frequency high-voltage dust removing transformer, comprise low-voltage coil, high-tension coil, primary insulation paper web, outer layer insulation paper web and iron core, low-voltage coil is wound on the primary insulation paper web outside, high-tension coil is wound on the outer layer insulation paper web outside, it is characterized in that: be provided with one group of little insulating paper cylinder between primary insulation paper web and outer layer insulation paper web.
Among the present invention, one group of little insulating paper cylinder is evenly arranged in the space of primary insulation paper web and outer layer insulation paper web formation.Primary insulation paper web and outer layer insulation paper web are supported by one group little insulating paper cylinder, and constitute an integral body.Primary insulation paper web, outer layer insulation paper web and one group of little insulating paper cylinder are made by the elasticity cardboard.
The present invention adopts one group of little insulating paper cylinder to replace original corrugated board structure, and the electric property of product is greatly improved, and electric capacity and dielectric loss have all satisfied requirement; And in the improved while of radiating condition, the high and low pressure coil obtains more reliable support.
The present invention makes double-deck main insulation tube by the elasticity cardboard, between the double hyer insulation tube, support integral body of formation with little insulating cylinder, after adopting one group little insulating paper cylinder to replace the Main Insulation Structure of Electric of corrugated board, compared with prior art, electric property of the present invention is greatly improved, and electric capacity and dielectric loss have all satisfied the requirement of dust removing transformer; And adopt insulating paper cylinder to replace corrugated board, and make radiating condition of the present invention get improvement, the high and low pressure coil obtains more reliable support.
The present invention is applicable to that 60kV electric pressure, operating frequency are in the dust removing transformer of 7～8kHz.
