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

FIELD: electrical engineering. SUBSTANCE: invention can be used while testing high-voltage switches for actuating capacity. Increased authenticity of results and enhanced reliability of synthetic circuit are obtained thanks to insertion of capacitors 2, 8 and 9 and manufacture of commutator in accord with bridge circuit which opposite branches are reactors 5, 6 and capacitors 8, 9. One diagonal of it is connected in parallel to leads of actuating voltage source 7 and the other one is commutating element 4. With closure of contacts of tested switch 3 commutating element 4 is punctured automatically and tested switch 3 appears to be connected through reactors 5, 6 to source 1 of actuating current. It leads to diminished delay of switching on of source 1 of actuating current and approximation of testing conditions to real ones. Simplification is achieved by reduction of number of elements of circuit. EFFECT: increased authenticity of results and enhanced reliability of synthetic circuit. 1 dwg
