Embodiment Construction

[0020] refer to figure 1 figure 2 , image 3 , is a spring operating mechanism for a high-voltage switch, mainly including a frame 1 and a spring frame 2 fixed below the frame 1 . Both the frame 1 and the spring frame 2 are integral cast aluminum frames. The frame 1 has two parallel vertical plates 5, vertically running through the two vertical plates 5, there are mutually parallel energy storage shafts 8, output shafts 11, closing semi-shafts 17, opening semi-shafts 18, and first pawl shafts. 14. A plurality of shafts such as the second detent shaft 19 . The spring frame is provided with an energy storage spring 3 and an opening spring 4, both of which are compression springs. The outer end of the energy storage shaft is movably connected to the energy storage spring 3 through the first crank 6 , and the outer end of the output shaft is movably connected to the energy storage spring 4 through the second crank 7 .

[0021] Between the two vertical plates 5, a closing cam...

Abstract

The invention relates to the field of the operation mechanism of a power switch, which discloses a spring operation mechanism used for a high-voltage switch. The power transmission of an energy storage shaft and an output shaft is realized by utilizing the matching of a switching-on cam and a power arm, a switching-on half shaft and an energy storage retention detent are utilized to execute a switching-on command, a switching-off half shaft, a switching-on retention detent and a retention arm are utilized to execute a switching-off command, the retention, the switching off and the restoration of the switching-on retention detent are skillfully realized, the retention arm, a restoration arm and the power arm are also integrated into a transmission crankarm, and the restoration arm and a restoration wheel are matched to realize the restoration of the energy storage retention detent. The functions of energy storage, switching on and switching off of the invention are simple and convenient to realize, the used components are fewer, and the manufacturing cost is low.
