ARRANGEMENT FOR POWER SMOOTHING OF TRACTION DIRECT CURRENT ENGINES

The invention pertains to the area of electrical engineering and may be used for prevention the slipping of electric transport system. The suggested arrangement for power smoothing of traction engine (fig.1) has three armature windings (1,2 and 3), additional pole windings (4,5 and 6) and excitation windings (7,8,9) which are connected in parallel. First circuit consists of diodes (10,11,12) and second circuit - of diodes (13,14,15). The armature windings (1,2,3) are connected in series with additional pole windings (4,5,6) and excitation windings (7,8,9). Diodes (10,11,12) are connected between common terminals of additional pole windings (4,5,6) and excitation windings (7,8,9). Diodes (13,1,4,15) are connected between second terminals of windings (4,5,6) and common terminals of armature windings (1,2,3). Hence, two removed circuits are created with diodes conductive polarity and number of diodes is equal to number of traction engines. This invention relates to electric engineering and can be used in electric vehicle antislip devices. Its goal is to increase the power equalization between traction motors.The proposed power equalizer (Fig. 1) includes traction motors where diodes are series-connected between common points of each excitation winding and each commutating pole winding. In addition, the diodes are additionally series-connected between common points of the second end of each commutating pole winding and an armature winding. Two separated loops are formed with the diode polarities in the same conductivity direction and the number of connected diodes corresponds to the number of traction motors.
