The grounding switch enables free interchange between electric and manual operation, and the grounding switch can be operated in a remote manner. The grounding switch is safe, reliable, and convenient in operation.
Description
Technical field
The utility model relates to a kind of earthed switch.
Background technology
Need to use earthed switch in multiple electric power system, manufacture the network artificial earthing while overhauling as high-voltage electrical equipment, to guarantee the maintainer, exempt from Danger Electric shock risk.Existing earthed switch mostly is manual type, by underframe, ground connection blade, earthed crank arm, V-type rotating shaft, post insulator and contact, formed, post insulator is contained on underframe, contact is contained on insulator, by ground connection blade, earthed crank arm and V-type rotating shaft, is fixed together the earthing erection that forms on underframe.Rotarily drive earthing assembling by manual operation V-type axle, be grounded blade and contact deciliter.Be that the manual operation ground switch rotating shaft is grounded switch and divides, closes action.Can not meet the desired Long-distance Control of intelligent power network, electric operating.
The utility model content
The purpose of this utility model is a kind of electric ground switch that is applicable to have Long-distance Control, operation of design.
The technical solution of the utility model is: a kind of electric ground switch, comprise underframe, ground connection blade, earthed crank arm, V-type rotating shaft, contact and post insulator, it is characterized in that, motor, deceleration device and secondary terminals are installed in the underframe installing hole, at V-type rotating shaft upper sleeve through, travelling gear is arranged, and mesh with the deceleration device internal gear, pin shaft hole is arranged on travelling gear, at V-type rotating shaft upper sleeve through, the electromagnetic clutch of synchronizeing with the V-type rotating shaft is arranged, be fixed with the location aided rebroadcast switch on underframe, secondary terminals is connected with controller.
Position transducer provides signal to controller, and secondary terminals provides wiring position to motor, location aided rebroadcast switch and controller.
When needs during away from the electrified body remote operation, start controller to the motor instruction, motor passes to the travelling gear in the V-type rotating shaft by deceleration device, electromagnetic clutch is charged simultaneously, electromagnetic core extend in the pin shaft hole of V-type rotating shaft upper transfer gear, stir iron core by travelling gear and make electromagnetic clutch and V-type rotating shaft synchronous rotary, earthing assembling rotation, be grounded blade and Contact Breaking/Making Operations.When electromagnetic clutch is not charged, electromagnetic core does not extend in the pin shaft hole of V-type rotating shaft upper transfer gear, and electromagnetic clutch and travelling gear are broken away from fully, realizes manual type adjustment and operation.
The electric ground switch structure that the utility model provides, increased motor drive mechanism on manual type earthed switch basis, electronic, manual operation is freely exchanged, but the remote operation earthed switch meets earthed switch security reliability, operation alternative and versatility requirement.Compact conformation is reasonable, makes simple, easy for installation, applied widely.
The accompanying drawing explanation
Fig. 1 is the structural representation of existing manual type earthed switch;
The structural representation that Fig. 2 is the utility model electric ground switch embodiment.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
In figure: 1, secondary terminals 2, underframe 3, motor 4, deceleration device 5, travelling gear
6, V-type rotating shaft 7, location aided rebroadcast switch 8, earthed crank arm 9, ground connection blade 10, electromagnetic clutch 11, contact 12, post insulator 13, controller
As shown in Figure 2, the utility model electric ground switch comprises underframe 2, ground connection blade 9, earthed crank arm 8, V-type rotating shaft 6, contact 11, post insulator 12, post insulator 12 is contained on underframe 2, contact 11 is contained on insulator 12, by ground connection blade 9, earthed crank arm 8, V-type rotating shaft 6 is fixed together the earthing erection that forms on underframe 2, it is characterized in that, in underframe 2 installing holes, motor 3 is installed, deceleration device 4 and secondary terminals 1, at V-type rotating shaft 6 upper sleeve throughs, travelling gear 5 is arranged, and mesh with deceleration device 4 internal gears, on travelling gear 5, pin shaft hole is arranged, at V-type rotating shaft 6 upper sleeve throughs, electromagnetic clutch 10 is arranged, with V-type rotating shaft 6, synchronize, be fixed with location aided rebroadcast switch 7 on bottom frame of grounding switch 2, secondary terminals 1 is connected with controller 13.
Location aided rebroadcast switch 7 is for providing signal to controller 13, and secondary terminals 1 provides wiring position to motor 3, location aided rebroadcast switch 7 and controller 13.
When the needs remote operation, start controller 13 to motor 3 instructions, motor 3 passes to the travelling gear 5 in V-type rotating shaft 6 by deceleration device 4, electromagnetic clutch 10 is charged simultaneously, electromagnetic core extend in the pin shaft hole of travelling gear 5, stir iron core by travelling gear 5 and make electromagnetic clutch 10 drive V-type rotating shaft 6 rotations, drive the earthing assembling, be grounded blade 9 and contact 11 deciliters; When electromagnetic clutch 10 is not charged, electromagnetic core does not extend in the pin shaft hole of travelling gear 5, and electromagnetic clutch 10 and travelling gear 5 are broken away from fully, realizes manual type adjustment and operation, meets earthed switch security reliability, operation alternative and versatility.
