Abstract

The invention relates to a kind of copper belt H class insulation dry-type hollow self-cooled flat wave electric reactor that comprises loop, insulation pressed board, stick, it characterized in that the loop is single-cake type, the inner brace is set in the inner layer of loop, the lead which enwinds the inner brace is bare copper belt, H class insulation duct bar is set between every circle of loop, H class insulation cushion block is set between nearby cakes, the loop is clamped by up and down insulation pressed board, and the H class insulation brace bar is set outside the loop, said inner and outer insulation brace bar, insulation duct bar, insulation cushion block adopts H class insulation material. The advantages are following: the structure is simple and reasonable, the electric property is good, the mechanical robustness is high, and radiation property is good, the temperature rise of loop is low, the volume is small, weight is light, the noise is low.

Description

technical field [0001] The invention relates to a dry-type hollow self-cooling smoothing reactor, which is widely used in direct current main circuits. Background technique [0002] At present, the traditional dry-type air-core self-cooling smoothing reactor is wound with copper wire or aluminum wire, and the insulation grade is generally B grade. to the wind. Reactor coil heat dissipation is difficult, current density Δ = 1.6a / mm 2 Next, these old dry-type air-core self-cooling smoothing reactors use many materials, are heavy, bulky, and costly, so they cannot achieve the best effect in electrical operation. Contents of the invention [0003] The object of the present invention is to provide a H-level insulating dry-type air-core self-cooling smoothing reactor wound with copper tape, which overcomes the technical deficiencies of the traditional dry-type air-core self-cooling smoothing reactor, and has a high insulation l...
