| description | The relevance of the discussed issue is caused by the need to improve the technology of winding impregnation to increase its quality and reliability. The main aim of the study: to justify the choice of magneto-dielectric impregnating compound and perspective of its use for alternative technology of winding impregnation in electrical and radio engineering products. The methods used in the study: the electro-thermal - to estimate heat conductivity and heat capacity; the electro-magnetic - to define the function of mixture magnetic conductivity from concentration of ferrite; the viscometers - to determine impregnating compound viscosity; capacitive - to control the saturation degree of interturn winding hole by impregnating compound; high-voltage - to investigate the electric strength of composition. The results. The authors found out that application of magneto-dielectric compound for impregnating the electrotechnical windings and radio technical coil products in the first place allows to eliminate all power-consuming, noisy electromechanical devices. Secondly, permits to provide the equal glazing of face parts. Thirdly, the using of magneto-dielectric compound allows to improve the saturation degree of interturn winding hole by impregnating compound. This is achieved through heating current supply to coil after the impregnation, magnetic force of which serves as a gate, whereby the impregnating composition stops to flow out of the cavities during their drying. The high thermal conductivity of the proposed mixture and high rates of impregnation can reduce overheating of the windings, which in several times increases their reliability and durability. It was shown, that the nickel-zinc soft magnetic particles can improve the conductivity of the impregnating mixture more than one and a half times. Thus, magneto-dielectric technological properties of the mixture (viscosity, dielectric strength, etc.) remain within acceptable limits. Higher thermal conductivity of the considered magneto-dielectric mixture, in comparison with the thermal conductivity of the compound KP-34, traditionally used for inkjet-drip impregnation of stator windings, as well as high rates of impregnation when using magneto-dielectric composition, make it possible to reduce overheating of the stator windings not less than 30 %. |
