Spring executing mechanism for domestic high voltage breaker

The utility model discloses a spring operating mechanism for an indoor high-voltage vacuum circuit breaker, which is used for closing and dividing a switch for the operation of an electric network in an electric power system. The left side of an energy storing shaft is hung and sheathed with an energy storing spring, the energy required by the mechanism is ensured, the fatigue strength of the spring and the size of space occupied by the spring are reduced. The operating mechanism for an indoor high-voltage vacuum circuit breaker has the advantages of compact structure, small size, low cost, convenient assemblage and perfect function, integrated solid sealed poles can be assembled, an insulating cylinder can be also arranged and packaged products in electric industries can be miniaturized.
