Background
The high-voltage switch (or high-voltage breaker) can cut off or close the no-load current and the load current in the high-voltage circuit, and cuts off the overload current and the short-circuit current through the action of the relay protection device when the system fails, and has quite perfect arc extinguishing structure and enough breaking capacity, and the contact base is an important part of the high-voltage switch.
The connection stability of the currently used contact seat and the contact is poor, short circuit is easy to generate, the safety is poor, and certain danger exists. In a GIS compensator or cable connection, for example, the contacts and the contact blocks form a contact system and are enclosed in a housing filled with an insulating gas. The contacts may be part of or connected to the conductors and connected by contact sockets. The high-voltage switch can be subjected to the action of electric force in the operation process to generate axial and radial displacement, and the contact is easy to generate axial and radial displacement. If the displacement is too large, the contact pressure between the contact and the contact finger on the contact seat is reduced, so that the contact resistance is increased, and the local temperature rise is increased, and even the normal operation of the high-voltage switch is affected.
