Description
Technical field
The present invention relates to a kind of utensil of earthing switch more particularly to a kind of operating mechanisms of earthing switch.
Background technology
The conjunction of earthing switch at present, such as middle pressure earthing switch divides the principle of operation mainstream to be：The spring mistake assembled with spring
Dead point mode realizes that i.e. centering pressure grounding switch main shaft progress energy storage is further continued for rotating small when spring is located at dead point state
Angle, energy-stored spring will release energy, press the moving contact of earthing switch to assemble quick rotation in drive, earthing switch is pressed in realization
Combined floodgate or separating brake.In concrete structure：Middle pressure earthing switch operating mechanism, including the assembly of mounting base, moving contact and spring assembly, should
Mounting base is equipped with the main shaft that can be rotated, and spring assembly includes spring, and moving contact assembly includes moving contact.Pacify at the main shaft
There are one the slide block for carrying recessing groove, the slide blocks to be fixedly connected with main shaft for dress；The moving contact is rotatably connected with main shaft；The bullet
Spring one end is rotatably connected by pin with moving contact, and the other end is rotatably connected by pin with mounting base.As the spindle turns, it drives and dials
Motion block rotates together, and by the connecting pin of spring and moving contact to spring energy-storage；When spring reaches dead-centre position, main shaft is again
Minute angle is rotated, spring will release energy, and band moving contact quick rotation presses the combined floodgate or separating brake of earthing switch in realization.
When spring quick rotation, because the connecting pin of spring and moving contact can be moved in the recessing groove in slide block, it can't drive and stir
Block moves, therefore main shaft will not be moved and then, to protect the safety of operating personnel.
The middle pressure earthing switch operating mechanism of concrete structure is because being equipped with the slide block with recessing groove, therefore there are as follows
It is insufficient：Increase parts, improve cost, complicated, assembly is inconvenient.
