Problems solved by technology
For the energy storage spring, it is very important to minimize the energy loss during the compression and release of the energy storage spring. In the existing energy storage compression technology, the energy loss of the energy storage spring is relatively large, and the utilization rate is not high. At the same time, in order to To meet sufficient spring compression stroke, the volume of the energy storage compression mechanism is large, which is not conducive to layout

The invention discloses a circuit breaker energy storage mechanism. The mechanism comprises two oppositely arranged side plates and a roller shaft installed between the two side plates, wherein two ends of the roller shaft are installed on the oppositely arranged side plates, the roller shaft can move back and forth under the action of a folding driving mechanism, and an energy storage assembly can achieve energy storage and energy release in the moving process of the roller shaft; the folding driving mechanism comprises a cantilever, one end of the cantilever sleeves the roller shaft, the other end of the cantilever is hinged to a compression frame, and the compression frame is mounted on the side plate through a rotating shaft and can rotate around the rotating shaft; the energy storageassembly comprises a movable spring seat in linkage with the roller shaft, one end of the energy storage spring set is connected with the movable spring seat, and the other end of the energy storage spring set is connected with the fixed spring seat. The mechanism is advantaged in that a folding driving mechanism is adopted for pulling the movable spring seat to compress the energy storage springset, the occupied space is small, arrangement is facilitated, and the size of the energy storage compression mechanism is effectively reduced; the movable spring seat compresses the energy storage spring set in a linear mode, and energy loss of the energy storage spring set is reduced.
Description
technical field [0001] The invention belongs to the field of circuit breakers, and in particular relates to an energy storage mechanism of a circuit breaker. Background technique [0002] A circuit breaker is a switching device that can close, carry and break current under normal circuit conditions and can close, carry and break current under abnormal circuit conditions within a specified time. A circuit breaker is generally composed of a contact system, an arc extinguishing system, an operating mechanism, a release and a housing, etc. The operating mechanism is used to complete the opening and closing operation of the circuit breaker and keep the circuit breaker in the closed position. [0003] At present, the operating mechanism of most circuit breakers is a mechanical operating mechanism, which uses an energy storage spring to store energy, and when the energy storage spring releases energy, it drives the closing connecting rod to rotate, thereby realizing the closing fun...
