EXPLOSIVE CURRENT BREAKER Russian patent published in 1998 - IPC

FIELD: electrical engineering. SUBSTANCE: invention refers to high-power commutation devices for A.C. and D.C. circuits. Current breaker includes tubular current carrying member filled with flow cooling dielectric and embraced with set of dielectric alternating rings with different inner diameter encompassed by insulation cylinder and explosive charge positioned on axis of current carrying member along its length. According to first version additional conductive member made in the form of round plate placed from butt of tubular member and insulated from cooling dielectric by dielectric sleeve in opposition to which cylindrical cavity with dielectric walls is formed on side of round plate is inserted in series with tubular current carrying member. In compliance with second version tubular current carrying member is filled with immobile dielectric and is manufactured in the form of two or more coaxial parts space between which is filled with flow cooling dielectric. EFFECT: enhanced operational reliability of explosive current breaker. 2 cl, 2 dwg
