Title:
ARC PATH FORMATION UNIT AND DIRECT CURRENT RELAY INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2021/112343
Kind Code:
A1
Abstract:
An arc path formation unit and a direct current relay are disclosed. The arc path formation unit according to an embodiment of the present invention comprises a plurality of magnet parts. Each magnet part is arranged adjacent to a plurality of fixed contacts. Opposing surfaces of the plurality of magnet parts located adjacent to one fixed contact and facing each other, the opposing surfaces facing each other, and opposing surfaces of the magnet parts located adjacent to another fixed contact, the opposing surfaces facing each other, are configured to have the same polarity. Accordingly, electromagnetic forces formed in the fixed contacts are formed in a direction away from each other and away from a central portion. Accordingly, damage to each configuration of the arc path formation unit and the direct current relay caused by a generated arc can be minimized.
