Abstract

The present invention provides an immobilized and encapsulated post terminal and a breaker provided with the immobilized and encapsulated post terminal. The breaker comprises the immobilized and encapsulated post terminal and an operating mechanism. The immobilized and encapsulated post terminal comprises a first contact and a second contact. The second contact is provided with a movable-end conductive rod. The operating mechanism is directly in transmission connection with the movable-end conductive rod. The first contact is in the form of a floating contact arranged by an elastic piece. According to the technical scheme of the invention, the operating mechanism is directly in transmission connection with the movable-end conductive rod. In this way, no insulated pull bar is adopted, and the weight of moving parts is reduced. The breaking-closing speed is improved. The first contact is in the form of the floating contact. Therefore, after the closing process, the second contact can push the first contact to move continuously. The elastic piece keeps a certain engagement pressure between the two contacts after being compressed, so that the closing performance is ensured to be good. The condition that the closing performance is affected due to the absence of an over-travel spring after the direct removal of the insulated pull bar can be avoided. Meanwhile, the elastic piece supplies an initial kinetic energy for the breaking of the second contact, so that the breaking speed is improved.

Description

technical field [0001] The invention relates to a solid-sealed pole and a circuit breaker using the solid-sealed pole. Background technique [0002] The embedded pole is to embed the conductive parts related to the vacuum interrupter and the circuit breaker into an easily curable solid insulating material such as epoxy resin to form a pole, so that the entire circuit breaker pole becomes an integral part. A general solid-sealed pole includes an upper outlet terminal, a vacuum interrupter, a lower outlet terminal and an epoxy resin insulator. The vacuum interrupter is provided with a static contact and a moving contact along the upper and lower directions, that is, the first contact and the second contact. Contact, wherein the moving contact is connected to the insulating rod through the moving conductive rod, and the other end of the insulating rod is connected to the operating mechanism. Contact and separation, so as to realize the opening and closing of the circuit breake...
