Output lever 54 is fixedly installed；Second drive rod 43 is arranged in the second operating shaft 41, suitable for doing together with the second operating shaft 41
Step rotation；Second upper lever 44 and the second lower lever 45 are socketed in the second operating shaft 41, are suitable for and the second operating shaft 41
It relatively rotates；Second gag lever post fixes setting, is suitable for limitation the second upper lever 44 rotation；Second upper lever 44
It is upper that lever and the second lower block for cooperating with the second lower lever 45 on second for cooperating with the second drive rod 43 are set
Bar；Described 46 one end of second connecting rod connects output lever 54, the lower lever 45 of 46 other end of the second connecting rod connection second.Second
Operating mechanism successively passes through the lower lever 45 of the second drive rod 43, the second upper lever 44, second, second connecting rod 46 and output lever
54, it drives output shaft 2 to rotate counterclockwise, output shaft 2 is made to be moved to ground connection separating brake station from contact of earth station, output shaft 2 exists
When rotating clockwise, the second pawl cannot limit the rotation of the second cam 42.
On-load switch of the invention when first operating shaft 31 rotates clockwise, can drive defeated through 36 mechanism of first connecting rod
Shaft 2 goes to ground connection separating brake station by contact of earth station, after output shaft 2 reaches ground connection separating brake station, 51 appliance for releasing single of locking bar
Enter, realizes the locking to output shaft 2；At this point, the first pawl of the first release lever 37 cannot limit the rotation of the first cam 32；The
When one operating shaft 31 rotates counterclockwise, the first pawl of the first release lever 37 withstands the first cam 32, and the first cam 32 drives
The rotation of first release lever 37, will first be detached from, then output shaft 2 does normal rotation, by being grounded between locking bar 51 and output shaft 2
Separating brake station goes to contact of earth station.
When second operating shaft 41 rotates counterclockwise, output shaft 2 can be driven by energization combined floodgate work through 46 mechanism of second connecting rod
Position goes to energization separating brake station, and after output shaft 2 reaches energization separating brake station, locking bar 51 is sprung into automatically, realizes to output shaft 2
Locking；At this point, the second pawl of the second release lever 47 cannot limit the rotation of the second cam 42；Second rotation clockwise of operating shaft 41
When turning, the second pawl of the second release lever 47 withstands the second cam 42, and the second cam 42 drives the rotation of the second release lever 47,
It will be first detached between locking bar 51 and output shaft 2, then output shaft 2 does normal rotation, goes to energization by energization separating brake station and closes
Lock station.
On-load switch of the invention can make the rotation of output shaft 2 to separating brake station (power-off opening station and ground connection separating brake work
Position) when, locking bar 51 can be inserted in the fore shaft of output shaft 2, and then limits output shaft 2 and rotate, and make its exact residence in separating brake work
Position, the stability of increasing productivity switching mechanism work.
