Abstract

The invention relates to a rotatable linkage double-moving-contact mechanism which can comprise an active contact component and a passive contact component rotatably mounted on a base and forming driving connection. Under action of an external force, the active contact component drives the passive contact component to rotate respectively along opposite directions to enable contacts of the active contact component and the passive contact component to contact with each other, and the active contact component and the passive contact component rotate at the same time along opposite directions under action of respective self-resetting members to separate their contacts. The rotatable linkage double-moving-contact mechanism is high in closing and opening speed and conducive to quick arc extinguishing, and voltage resistance is improved.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a rotary linkage double-action contact mechanism and a switch circuit breaker. Background technique [0002] In the existing moving and static contact contact system composed of rotatable moving contacts and static contacts, the engagement and disconnection of the moving contacts and the static contacts can only be realized by the rotation of the moving contacts. This kind of dynamic and static contact contact system mainly has the following problems: [0003] 1. Due to the limited opening distance and breaking speed of the existing dynamic and static contact contact system, its withstand voltage level and short-circuit breaking capacity cannot be further improved; [0004] 2. The existing dynamic and static contact contact system only has one moving contact to rotate, and the action time of breaking the circuit is too long, the arc extinguishing time is long, the damage to t...
