Detailed Description
The following detailed description of the preferred embodiments of the present invention will be provided in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, and the scope of the present invention can be more clearly and clearly defined.
Referring to fig. 1-4, a load switch operating mechanism of a ring main unit without reverse energy storage comprises a closing spring 3 and a main spring 9 arranged in the mechanism, an upper spring hanging plate 2 and a lower spring hanging plate 4 for installing the closing spring 3 are also arranged in the mechanism, the upper spring hanging plate 2 is fixed on a first F-JG-shaft 1, the lower spring hanging plate 4 is welded on a crank shaft 5, the crank shaft 5 is connected on a second F-JG-shaft 6, a gear shaft 7 is arranged beside the second F-JG-shaft 6, a switching cam 10 and a cam 11 are connected on the second F-JG-shaft 6, the switching cam 10 and the cam 11 are connected with a gear shaft 7, the gear shaft 7 is connected with the main spring 9, a closing operating shaft 8 is connected on the main spring 9, and a switching-off button 12 is also arranged on the mechanism, the closing spring 3 can be matched with the opening and closing cam 10 and the cam 11 to act through the crank arm shaft 5 and the F-JG-shaft II 6.
The utility model discloses a theory of operation: when the operating handle is inserted into the closing operation shaft 8, the main spring 9 acts, then the gear shaft 7 drives the opening and closing cam 10 and the cam 11 to move, the opening and closing cam 10 and the cam 11 drive the second F-JG-shaft 6 to move, the second F-JG-shaft 6 drives the crank arm shaft 5 to move, and finally the crank arm shaft 5 drives the closing spring 3 to act. Therefore, the energy is stored when the switch-on is simultaneously driven, and the energy is stored at the moment when the switch-on is not finished; after the closing is finished, the opening button 12 is pressed down, and the mechanism opens the brake instantly.
In conclusion, the hard interlocking is adopted in the utility model, so that the interlocking is convenient and reliable; after the pressure spring mechanism is adopted for switching on, reverse energy storage is not needed, so that tripping is simple in emergency, and the device has the advantages of convenience in installation and replacement and simplicity in maintenance.
The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment, but all equivalent modifications or changes made by those skilled in the art according to the present invention should be included in the protection scope of the claims.
