| titleOfInvention | The production method and casting mold of open-close type zero sequence transformer |
| abstract | The present invention relates to a kind of production method of open-close type zero sequence current mutual inductor, the production including two cut cores, coiling, the die-filling moulding by casting of body, the processing steps such as assembling of semi-circular body casting matrix.Die ontology be by hemizonid, be arranged in hemizonid two sides left and right template and top cover board assembling constitute, there is semi-annular cavity in mold, cover inner surface setting is provided with the strong magnets for adsorbing doroid iron core to be cast there are two groove in groove.Its main feature is that: the production method shortens the production cycle of product, improves the qualification rate that product is once gone into operation, reduces production cost.Mold uses modular construction, and manufacturing cost is low, and assembling and convenient disassembly are quick, reduces labor intensity, improves labor efficiency.Doroid iron core is lifted by the way of utilizing powerful magnet for adsorption, adsorption capacity is big, accurate positioning, it will not change after the positioning of doroid iron core, so that the insulator of transformer thickness of moulding by casting is identical, guarantees the insulation performance of product, also improve product qualification rate. |
