SYNTHETIC CIRCUIT TO TEST COMMUTATIONAL HIGH-VOLTAGE APPARATUSES Russian patent published in 1997 - IPC

FIELD: electrical engineering. SUBSTANCE: invention can be used to test high-voltage commutational apparatuses for actuating capacity. Synthetic circuit is supplemented with capacitor 8, shunting actuating current source 1, capacitors 5 and 6. Commutator is manufactured in the form of bridge circuit which opposite branches are reactors 3, 4 and capacitors 5, 6. First diagonal of bridge circuit connects second leads of actuating current and voltage sources 1 and 2, object of test-commutational apparatus 9 is connected in parallel to the latter. Commutating element 7 is second diagonal of bridge circuit, it is switched on automatically at moment of puncture of intercontact gap of commutational apparatus 9. Design of circuit diminishes delay of connection of actuating current source 1 which makes test more realistic. Simplification and enhanced reliability of circuit are achieved by reduction of number of elements of circuit. EFFECT: increased authenticity of results of test and enhanced reliability of synthetic circuit. 5 cl, 3 dwg
