摘要
An axial magnetic field vacuum interrupter (1) includes a field producing structure (31) associated with only one of two opposing electrode assemblies (11, 13). The field producing structure (31) is characterized in that when the instantaneous arc current is Im, measured in kiloamperes, and the electrode assemblies (11, 13) are in the open circuit position, the instantaneous component of B in the axial direction Ba, measured in milliteslas, imposed on the majority of each electrode contact surface (27, 29) is given by the analytical expression 5Im BakA/mT /= 3.2(Im - 9kA).
