Abstract:
The present invention discloses a sealed HVDC relay, comprising an insulating hood and a yoke plate which is extended upward to form a cylindrical fixing portion; the insulating hood has an overturned cup structure; a chamber for accommodating moving contacts and stationary contacts is formed by the yoke plate and the insulating hood together; a lower end of the insulating hood and the fixing portion of the yoke plate are fitted with each other by threads; and the portion fitted by threads between the lower end of the insulating hood and the fixing portion is sealed by adhesive pouring. In the present invention, with the insulating hood made of ceramics, the stiffness of the relay structure of the present invention is promised. The absence of a brazing process makes the relay of the present invention short in manufacturing period and low in cost. With regard to the present invention, the sealing performance of the relay is promised by adhesive pouring, and a service voltage of the relay can be increased. In this way, the voltage of the relay of the present invention can reach 1000 V, thus improving the application performance of the present invention.
