FIELD: electrics. ^ SUBSTANCE: switchboard includes a number of sequential threshold commutation elements (dischargers P1?P10) forming straight current duct, with outputs featuring weak capacitance connection to reverse current duct 1 of switchboard, and two splitter circuits out of passive capacitance elements. Each main passive capacitance element (C1?C5) of first splitter circuit is connected parallel to neighbour commutation elements starting from first P1 and second P2 elements. Each main passive capacitance element (C6?C9) of second splitter circuit is connected parallel to two neighbour commutation elements starting from second P2 and third P3 elements. Each of two additional passive capacitance elements C10, C11 of second splitter circuit is connected parallel to one commutation element (P1, P10). Short launch impulse is put to clamp 8. ^ EFFECT: possible increase of commuted voltage and switchboard application in high voltage devices with nanosecond process synchronisation against launch impulses, reduce power loss and switchboard closing time. ^ 2 cl, 2 dwg |
