Abstract
Purpose. There are considered in the paper the four possible configurations of electromagnetic screens for compensation of the flux leakage of slots in the electromechanical pulse generator with a compression of magnetic flux. It is underlined the expediency of slot leakage inductance reduction as the method for increasing of coefficient of magnetic energy amplification in the process of flux compression. Methodology. Efficiency of each configuration of screens has been evaluated on the reduction of slot leakage inductance magnitude. To realize it the problem of pulsed field distribution in the teeth zone of generator has been solved by the finite elements method with application of professional version of software program QuickField v.6.1. Originality. There was manufactured the physical model of teeth zone in which the active conductor of slots was divided on 9 parallel sections along the height of slot. Results. With current supply from the source of alternating current at frequency 400 Hz that was measured a current distribution between the sections of active conductor both at the absence of electromagnetic screens and at their presence. Practical value. It is shown, that screening of slot leakage flux provides the more uniform distribution of current along the sections of active conductor with a corresponding reduction of slot leakage inductance..
