  • High voltage relay device
    Patent number: 9875859
    Abstract: A high voltage relay device according to the present invention includes fixed contacts, a movable contact provided at one side of the fixed contacts and contactable with or separated from the fixed contacts, fixed-side arc electrodes coupled to the fixed contacts, and a movable-side arc electrode coupled to one side of the movable contact and contactable with or separated from the fixed-side arc electrodes when the movable contact is brought into contact with or separated from the fixed contacts, whereby a generation of arc from primary electrodes when current flows and is cut off can be prevented so as to enhance reliability of the primary electrodes, and also usage of specialized materials may result in reduction of material costs.
