The electromechanical generator of pulsed current which operational principle is based on the magnetic flux compression is the specific kind of electrical machine whose design and development needs a modern scientific approach. The high efficiency of generator application is possible at condition that the big swing of internal inductance variation of machine is provided in its design at the rotation of rotor. Mainly it can be reached owing to reduction of minimal inductance of machine in the

... se of the magnetic flux compression. The electromagnetic shielding of the flux leakage in the slots of electromechanical pulsed generator with a compression of magnetic field is under consideration in this paper. Two design solutions of shields have been tested in the static experimental model of generator active zone part. The first variant of screen consists of two copper plates with insulation cover which are installed along the inner walls of slot. The second variant of screen consists of two copper plates of the same width as slot has. One of this plates is situated at the bottom of slot and other plate is situated at the neck of slot, and such a pair of plates has a connection between their edges by the copper crosspieces out of the space of slot. The new design of winding keeper is proposed for the increase of the total inductance swing. The group of slots which belong to the each pole division of winding are placed in the conducting block which in turn is places in the wide slot of magnetic core. This solution allows to reduce a magnetoconductivity for the flux directed across the slots. The principle of magnetic shielding operation has been demonstrated with application of numerical simulation of pulsed magnetic field passage across the screen, software COMSOL v. 3.5 has been used for this purpose. Some results of shielding simulation are reported, and problems of development and simulation of the screens for the flux leakage compensation have been discussed.
