Abstract:
The present invention discloses an opposite arc isolation device of a high voltage direct current relay, including a movable contact assembly and a fixed contact assembly, wherein the movable contact assembly includes a movable spring plate and a left movable contact and a right movable contact fixed at left and right ends of the movable spring plate; the fixed contact assembly includes a left fixed contact corresponding to the left movable contact and a right fixed contact corresponding to the right movable contact; an arc isolation member made of insulating material is provided between the left movable contact and the right fixed contact; the front-to-rear dimension L of the arc isolation member is greater than the front-to-rear width M of a joint surface of the movable contacts with the fixed contacts; and, the arc isolation member has a height H that enables the isolation of opposite arcs between the two sets of movable and fixed contacts.

Claim (Index 3):
The opposite arc isolation device of a high voltage direct current relay according to  claim 1 , wherein the arc isolation member is formed by extending downward an insulating plate or an insulating cavity; a groove is formed between the left movable contact and the right movable contact of the movable spring plate, and the groove runs through the movable spring plate in a front-rear direction; and, when the movable spring plate moves up to allow the left movable contact to come into contact with the left fixed contact and the right movable contact to come into contact with the right fixed contact, the lower end of the arc isolation member is located within the groove.
