Abstract:
An arc path forming unit and a direct current relay are disclosed. An arc path forming unit according to an embodiment of the present disclosure comprises: a magnet frame extending in a longitudinal direction; and a plurality of main magnet units disposed in the width direction of the magnet frame. The surfaces, which face each other, of the main magnet units have the same polarity. Therefore, magnetic fields that repel each other are generated in a space between the respective main magnet units. An electromagnetic force in the direction oriented toward the outside of the arc path forming unit is formed by means of the magnetic fields. Thus, a generated arc can move in the direction of the electromagnetic force so as to be stably extinguished. As a result, various members positioned in the center of the direct current relay are prevented from being damaged by the arc.
