CONTACT ARC-SUPPRESSING DEVICE Russian patent published in 2004 - IPC

FIELD: electrical engineering.

SUBSTANCE: device has arc-suppressing chamber, current-carrying buses whose longitudinal symmetry axes lie in one plane, bridge contact system whose movable contacts are arranged in the ports of the crosspiece along the longitudinal axes of symmetry of the current-carrying buses.. At least one permanent magnet is mounted directly on the crosspiece under the bridge of the movable contacts providing the total vector of magnetizing of the permanent magnet to be oriented perpendicular to the axis of symmetry of current-carrying buses and the bridge of movable contacts.

EFFECT: enhanced reliability and simplified design.
