Embodiment
Describe concrete structure of the present invention in detail according to Fig. 1～3.The small modular operating mechanism that this three stations isolation earthing switch is used comprises installing rack 1 for fixing isolating switch pole, utilize parts such as the rotating shaft of the bearing pedestal 2 that is fixed on the installing rack 1 and support 10 assemblings and mechanism body.Its shaft is the hollow shaft 3 that inner chamber is provided with straight plate torsion spring 4.Periphery is that an end of hexagonal hollow shaft 3 and straight plate torsion spring 4 utilizes same axle sleeve 5 to be assembled on the bearing pedestal 2.Week was hexagon in the cross section of axle sleeve 5 adopted, and periphery is circular sleeve, can together rotate with the sliding bearing in hollow shaft 3 and the bearing pedestal 2.
Mechanism body comprises clamping plate type framework 6, be assembled in the ratchet 9 in the framework 6, a plurality of ratchets that are meshed with ratchet 9 peripheries are as separating brake ratchet 11, splice grafting ground ratchet 12, branch ground connection ratchet 13 and combined floodgate ratchet 14, cam 8, operating axis 7 parts such as grade that drive cam shaft is rotated.Mechanism body is fixed on the support 10 of installing rack 1 other end.The other end of hollow shaft 3 and ratchet 9 coaxial fixedlying connected rotate together.The axle center of the cam 8 that operating axis 7 drives and the axle center of ratchet 9 are positioned on the same axis.Operating axis 7 driving cams 8 rotate, can drive on the diverse location ratchet 11～14 respectively with the clutch of ratchet 9, ratchet 9 and hollow shaft 3 rotated simultaneously or stop simultaneously.The other end of straight plate torsion spring 4 is fixedlyed connected with camshaft, and rotates the storage of finishing energy with cam 8, also can finish the release of energy with the rotation of ratchet 9 and hollow shaft 3.When the axle of operating axis 7 driving cams 8 rotates, and ratchet 9 is withstood when no longer rotating by one in the ratchet 11～14, and then 4 this moments of straight plate torsion spring are by energy storage.When the boss of cam 8 peripheries of rotating backed down in the ratchet 11～14 one, straight plate torsion spring 4 just released energy, thereby driving pawl 9 and hollow shaft 3 rotate, and when ratchet 9 is withstood by next ratchet, stop operating.
During separating brake, use the counterclockwise actuating operating axis 7 of operating grip, operating axis 7 driving cams 8 and straight plate torsion spring 4 rotate, because an end of straight plate torsion spring 4 and hollow shaft 3 is fixed on the axle sleeve 5, the other end of hollow shaft 3 and ratchet 9 are fixing, the stop of separating brake ratchet 11 can not be rotated ratchet 9 and hollow shaft 3, so straight plate torsion spring 4 is by energy storage.When cam 8 backed down separating brake ratchet 11, ratchet 9 lost stop, and the spring energy stored is released, and the energy drives ratchet 9 of abrupt release and hollow shaft 3 rotate, and realize the quick acting switching-off of operating mechanism.When splice grafting ground ratchet 12 withstood ratchet 9, hollow shaft 3 stopped operating.Realize that by spring 15 separating brake ratchet 11 resets, realize the isolated operation of three station isolation earthing switch this moment.
During splice grafting ground, use the counterclockwise actuating operating axis 7 of operating grip, operating axis 7 driving cams 8 and straight plate torsion spring 4 rotate, because the stop of splice grafting ground ratchet 12, ratchet 9 and hollow shaft 3 can not rotate, so straight plate torsion spring 4 is by energy storage.When cam 8 backed down splice grafting ground ratchet 12, ratchet 9 lost stop, and the spring energy stored is released, and the energy of abrupt release promotes ratchet 9 and hollow shaft 3 rotates.When combined floodgate ratchet 14 withstands ratchet 9, hollow shaft 3 stops operating.Realize that by spring 15 splice grafting ground ratchet 12 resets, realize the ground connection operation of three station isolation earthing switch this moment.
When dividing ground connection, use the clockwise actuating operating axis 7 of operating grip, operating axis 7 driving cams 8 and straight plate torsion spring 4 rotate, because the stop of combined floodgate ratchet 14, ratchet 9 and hollow shaft 3 can not rotate, so straight plate torsion spring 4 is by energy storage.When cam 8 backed down combined floodgate ratchet 14, ratchet 9 lost stop, and the spring energy stored is released, and the energy of abrupt release promotes ratchet 9 and hollow shaft 3 rotates, and realizes the quick ground connection of operating mechanism.When a minute ground connection ratchet 13 withstands ratchet 9, hollow shaft 3 stops operating.Realize that by spring 15 combined floodgate ratchet 14 resets, realize the branch ground connection operation of three station isolation earthing switch this moment.
During combined floodgate, use the clockwise actuating operating axis 7 of operating grip, operating axis 7 driving cams 8 and straight plate torsion spring 4 rotate, owing to divide the stop of ground connection ratchet 13, ratchet 9 and hollow shaft 3 can not rotate, so straight plate torsion spring 4 is by energy storage.When cam 8 backed down branch ground connection ratchet 13, ratchet 9 lost stop, and the spring energy stored is released, and the energy of abrupt release promotes ratchet 9 and hollow shaft 3 rotates, and realizes the quick ground connection of operating mechanism.When separating brake ratchet 11 withstands ratchet 9, hollow shaft 3 stops operating.Realize dividing ground connection ratchet 13 to reset by spring 15, realize the closing operation of three station isolation earthing switch this moment.
