Title:
旋回永久磁石を有する電磁アシストアーク消滅
Document Type and Number:
Japanese Patent JP6290333
Kind Code:
B2
Abstract:
A circuit interrupter 100 configured to aid in rapidly extinguishing an electrical arc regardless of the polarity of current through a circuit interrupter, and during low current conditions. Various implementations of the circuit interrupter incorporate an electromagnet 705 and a pivoting permanent magnet 192, 705. These structures produce additive magnetic fields that create a force on an arc 190 between the contacts 120, 140, urging it toward an arc arresting structure 191 regardless of the electrical polarity of the circuit interrupter or the magnitude of the current through the circuit interrupter.
