Title:
ELECTROMAGNETICALLY ASSISTED ARC QUENCH WITH PIVOTING PERMANENT MAGNET
Document Type and Number:
Japanese Patent JP2017041445
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a circuit interrupter configured to aid in rapidly extinguishing an electrical arc during low current conditions regardless of the polarity of current through a circuit interrupter.SOLUTION: Various implementations of the circuit interrupter incorporate an electromagnet and a pivoting permanent magnet. These structures produce additive magnetic fields that create a force on an arc between the contacts, urging the arc toward an arc arresting structure regardless of the electrical polarity of the circuit interrupter or the magnitude of the current through the circuit interrupter.SELECTED DRAWING: Figure 1
