FIELD: transport engineering; garage electrical equipment. ^ SUBSTANCE: proposed device contains capacitive energy accumulator made in form of two capacitors with double electric layer. With thyristor and current-limiting resistor placed in charging circuit, first switch with making contact and semiconductor with unidirectional conduction shunting series-connected thyristor and resistor at flow of energy accumulator discharge current. Device is furnished with electromagnetic contactor whose breaking contacts provide parallel connection of capacitors, and first making contact, their series connection by at least two-terminal connector for connecting capacitors to electric system of object with internal combustion engine and electric starting system. Winding of contactor is connected to connector through series- connected voltage stabilizing diode, above-indicated first switch with making contact and second two-circuit switch with making contacts. Second making contact of contactor shunts circuit consisting of first switch and voltage stabilizing diode. ^ EFFECT: improved safety and convenience in operation owing to provision of automatic change over of capacitors from parallel into series connection when object with rated voltage of 24 V is connected to electric system. ^ 6 cl, 1 dwg |
