Embodiment
Now by reference to the accompanying drawings, the specific embodiment of the invention is described in detail in detail:
As shown in Figure 1 and Figure 2, a kind of Dual-power automatic switching sulfur hexafluoride loading switch, comprises operating mechanism 1, switch underframe 2, and operating mechanism 1 is connected in the front portion of switch underframe 2; The left and right sides of switch underframe 2 is respectively equipped with left-handed opening body and right Switch main body; Right Switch main body structure and left-handed opening body construction are symmetrical; Left-handed opening body comprises main shaft 3, grounding shaft 4, upper insulator cap 5, lower insulator 6, piston rod 7, conductive tube 8, isolation connecting lever 10, and upper insulator cap 5 is connected in the top of switch underframe 2, in upper insulator cap 5, is provided with upper contact head 51; Main shaft 3 is connected in the middle part of switch underframe 2, and main shaft 3 is rotatable with respect to switch underframe 2, simultaneously between left-handed opening body and right Switch main body; Main shaft 3 one end are connected with operating mechanism 1; Grounding shaft 4 is connected on switch underframe 2, and is positioned at the below of main shaft 3; Lower insulator 6 is connected in the bottom of switch underframe 2, and be positioned at insulator cap 5 under; Piston rod 7 is copper pipe, and it is connected on lower insulator 6 by busbar 9; Conductive tube 8 is sheathed on piston rod 7; Conductive tube 8 can move up and down with respect to switch underframe 2; Isolation connecting lever 10 one end are connected on main shaft 3, and one end is connected with the outer wall of conductive tube 8.
Main shaft 3 of the present invention and grounding shaft 4 are provided with sealing ring with the junction of switch underframe 2.
The back-to-back layout that adopts left-handed opening body of the present invention and right Switch main body is fixed on same switch underframe 2, upper insulator cap 5 is fixed on the upper end of switch underframe 2, lower insulator 6 is fixed on the lower end of switch underframe 2, on lower insulator 6, be fixed with respectively busbar 9, piston rod 7, piston rod 7 adopts copper pipe to make, conductive tube 8 is sheathed on outside piston rod 7, main shaft 3 is through in the middle of switch underframe 2, isolation connecting lever 10 one end are fixed on main shaft 3, the other end is connected with conductive tube 8, grounding shaft 4 is fixed on switch underframe 2, and is positioned at the below of main shaft 3; Main shaft 3, grounding shaft 4 are provided with sealing ring with the junction of switch underframe 2, and left-handed opening body and right Switch main body are sealed in a shell, and sulfur hexafluoride gas is filled in inside, and operating mechanism 1 is fixed on enclosure.
When the present invention closes a floodgate, principal axis A on operating mechanism 1 drives the main shaft 3 on right Switch main body clockwise, thereby drive the isolation connecting lever 10 on right Switch main body to clockwise rotate, separate thereby drive conductive tube 8 to move downward with the fingertip of the upper contact head 51 of 3 li of upper insulator caps, move thereby realize separating brake.Now left and right switch is in two points of states.If continue clockwise operating mechanism main shaft A, right switch spindle motionless (switch is in gate-dividing state).At this moment just drive main shaft 3 left sides on left-handed opening body, thereby drive the isolation connecting lever 10 on left-handed opening body to clockwise rotate, realize left-handed opening and close a floodgate.
More than move: 1) right switch separating brake; 2) left-handed opening closes a floodgate, and has completed one point, the conversion of combined floodgate.Otherwise, if the principal axis A on counterclockwise operating mechanism 1 just can complete: 1) left-handed opening separating brake; 2) right switch closes a floodgate, and has completed again one point, the conversion of combined floodgate.
Illustrate: the conversion that 1) divides, closes a floodgate is only by the principal axis A execution (uniqueness) on operating mechanism 1, does not have misoperation.2) action be all first to divide, after close.3) action can be continuous, can also separate.Namely left and right switch can be in two points of states.
