Title:
アーク経路形成部及びそれを含む直流リレー
Document Type and Number:
Japanese Patent JP7358630
Kind Code:
B2
Abstract:
Disclosed are an arc path forming unit and a direct current relay comprising same. The arc path forming unit according to an embodiment of the present invention comprises a single magnet unit disposed on one side of a magnet frame, and a plurality of magnet units disposed on another side opposite to the one side. The plurality of magnet units are sequentially arranged in the longitudinal direction. One side of a magnet unit positioned between at least two of the plurality of magnet units and facing the single magnet unit is magnetized with the same polarity as that of one side of the single magnet unit facing the magnet unit. As such, magnetic fields in the direction of exerting repulsive forces on each other are formed in the central portion of the direct current relay. Accordingly, since the arc does not move to the central portion, damage to components disposed in the central portion can be prevented.
