Abstract: A high voltage relay resistant to instantaneous high-current impact is disclosed, and includes an electromagnet system, a control system, a contact system, and a base support. In the present solution, an electromagnetic force generated by the contact system is used to resolve a problem of contact separation caused by an electric repulsion force generated by an instantaneous high-current.

Abstract: The disclosure relates to a flexible automatic clamping device and method for backside laser penetration welding of a T-shaped structure. The flexible automatic clamping device includes a clamping system, a ranging system and a control system. The ranging system outputs a position instruction to the control system, the control system outputs a movement instruction to the clamping system, so as to adjust the clamping system to an optimal position, then a stringer pressing plate fastens a stringer by means of a Y-shaped connecting rod, and a skin pressing plate fastens skin by means of a skin connecting rod. Based on the flexible automatic clamping device, the method includes prewelding clamping, backside laser penetration welding and postwelding shape retention. The disclosure implements accurate positioning, automatic clamping, backside laser penetration welding and postwelding shape retention of a T-shaped skin-stringer structure.
