Ovcharov S. Operational conditions of activity asynchronous motors of line contribution links in conditions of agriculture

The object is processes of the consumption of resource of isolation and electromechanical transformation of energy in asynchronous motors at influencing operational effects in conditions of an agroindustrial complex; the aim is improvement of operational parameters of asynchronous electric motors of line contribution links in conditions of agriculture by the objective continuous control both diagnosing of operational conditions of activity and protection of electric motors on the basis of generalized model of processes of the consumption of resource of isolation and electromechanical transformation of energy under influencing of operational effects and facilitation of stand-by modes at the expense of association of dead centers of a winding of statorsor; the methods are symbolical method of the analysis of electric networks, method symmetrical component, method of the pie charts; a method of the analysis of linear electric networks; a method of correlation analysis; the novelty is designed a new mathematical model of processes of the consumption of resource of isolation and electromechanical transformation of energy in an asynchronous motor at association of dead centers of a winding in case of loss of a phase or impairment of a contact in a switchgear; the outcomes are designed the design solutions of devices of the continuous control of operational conditions of activity and protection of asynchronous motors of line contribution links; is inserted in agroindustrial complex and formation; the field is maintenance of electric equipment.
