Abstract
The utility model relates to a hand operated energy storing structure of a spring operating mechanism, composed of a handle, a crank arm, a connecting plate, a driving ratchet, a holding ratchet, a ratchet wheel, a cam wheel, an energy storing shaft, a supporting plate, an energy storing spring, an output shaft, a rocker arm, a semi-shaft, etc. The utility model changes a cantilever state energy storing shaft in the prior art into a double-support structure and additionally provides the supporting plate. Most of supporting force provided by the supporting plate can counteract radial pulling force created by the energy storing spring to the energy storing shaft in energy storing processes. The mechanical strength of the shaft is raised, and thus, the energy storing amount of the spring is increased. Therefore, the maximum open-break force can reach 20 KA current. In addition. The operating mechanism can keep relative stability, and the working reliability is raised.
Description
The utility model relates to the manual energy storing structure that the operating mechanism of outdoor vacuum circuit breaker is used for closing a floodgate in the high voltage electric appliance.
