Description
Technical field
The utility model relates to a kind of sulphur hexafluoride (SF that is used for
6) the gas-insulated metal make and break closes the direct action type three-station of equipment, belongs to the technical field of High-Voltage Electrical Appliances.
Background technology
The existing SF that is used for
6Mostly the three-station of Cubicle Gas-Insulated Switchgear is to use guillotine type.Three-station need cut-off, close and close rated short circuit current, also just requires the responsiveness of three-station will reach certain value; When the guillotine type three-station is in the service position, must there be certain power of holding tightly to guarantee to conduct electricity reliability between blade and the contact.This just makes the operating mechanism more complicated of three-station, and operating physical force is big.
Summary of the invention
The utility model purpose is the defective at above-mentioned existence, proposes a kind of SF that is used for
6The direct action type three-station of Cubicle Gas-Insulated Switchgear.Solution of the present utility model is as follows: spring conduction fingertip is installed in fixed contact in pairs respectively, in the groove of middle contact and fixed contact correspondence, middle contact is installed on the leading-out terminal of circuit breaker by screw, fixed contact is fixed on the branch bus, and be fixed on the boss of insulating sleeve of circuit breaker, guider screw screws in the screwed hole of middle contact correspondence, moving contact inserts in the middle contact, guarantee in the gathering sill on the guider screw insertion moving contact, circuit breaker is fixed on the mounting panel, fixed contact, ground connection row, short circuit row, mounting panel is installed on the mounting panel one by one, leading screw inserts from the hole of fixed contact and screws in moving contact, and sealed coupler one end is connected with pin with leading screw and is fixed on the mounting panel.
The middle contact in the direct action type three-station and the fixed contact of service position are installed in respectively on the leading-out terminal and insulating sleeve of circuit breaker, the fixed contact of earthing position is installed on the mounting panel by bent plate, mounting spring conductive contact on middle contact and the fixed contact, moving contact is installed between the fixed contact of middle contact and earthing position, leading screw inserts and screws in the moving contact in the fixed contact hole of earthing position, and sealed coupler is connected with leading screw and is fixed on the mounting panel.
Advantage of the present utility model: the conduct of use circuit breaker is cut-off, the element of making current, and three-station only need be finished the work of electrical connection.And the action of moving contact drives by leading screw and moves along axis direction.The operating mechanism of three-station is fairly simple, and reliability improves greatly.
Description of drawings
Accompanying drawing is a structural representation of the present utility model.
Among the figure 1 is circuit breaker, the 2nd, branch bus, the 3rd, fixed contact, the 4th, spring conduction fingertip, the 5th, middle contact, the 6th, guider screw, the 7th, moving contact, the 8th, fixed contact, the 9th, ground connection row, the 10th, short circuit row, the 11st, leading screw, the 12nd, mounting panel, the 13rd, sealed coupler, the 14th, mounting panel.
Embodiment:
The contrast accompanying drawing is installed in respectively in the groove of fixed contact 3, middle contact 5 and fixed contact 8 correspondences in pairs with spring conduction fingertip 4.Then middle contact 5 is installed in the leading-out terminal of circuit breaker 1 by screw, fixed contact 3 is fixed on earlier on the branch bus 2, is fixed on the boss of insulating sleeve of circuit breaker 1 again.Guider screw 6 screws in the screwed hole of middle contact 5 correspondences.In the middle of inserting, moving contact 7 in the contact 5, guarantees the gathering sill that guider screw 6 inserts on the moving contact 7.The circuit breaker 1 that above element has been installed is screwed on mounting panel 14.Then fixed contact 8, ground connection row 9, short circuit row 10, mounting panel 12 are installed on the mounting panel 14 one by one.Leading screw 11 is inserted and screw-in moving contact 7 from the hole of fixed contact 8, and sealed coupler one end is connected with pin with leading screw and is fixed on the mounting panel 14.
Circuit breaker 1 is that three-station cut-offs, the element of making current.Branch bus 2 is the mounting panel of the fixed contact 3 of service position, is again the electrical connecting element that connects main bus bar.Fixed contact 3, spring conduction fingertip 4, middle contact 5, moving contact 7, fixed contact 8 all are the electrical connecting elements of galvanic circle, when moving contact 7 was connected fixed contact 3 with middle contact 5, circuit breaker 1 closed a floodgate, and the galvanic circle is in the service position, the galvanic circle is connected, the switchgear operate as normal; When moving contact 7 was connected fixed contact 8 with middle contact 5, circuit breaker 1 can only close a floodgate under the situation of cable side dead electricity, and the galvanic circle is in earthing position, at this moment can inspection switch equipment; When moving contact 7 inserted centre contact 5 fully, the galvanic circle was in the isolated location, and the galvanic circle disconnects.Guider screw 6 is used for preventing that moving contact 7 from rotating and lead in motion process.Three-station is three groups in use to be used simultaneously, and short circuit row 10 is used for connecting the fixed contact 8 of three groups of three-stations.Ground connection row 9 is used for fixed contact 8 is connected to the grounded circuit of switchgear.Mounting panel 12 is installing racks of fixed contact 8.Mounting panel 14 is reference for installation of three-station.Leading screw 11 is actuating elements of moving contact 7.Sealed coupler 13 is the conversion links between the actuating element leading screw 11 of the operating mechanism of three-station and three-station, is the operating mechanism of three-station and the seal between the three-station simultaneously.The output of the operating mechanism of three-station and 13 rotations of sealed coupler 13 connecting band movable sealing shaft couplings, sealed coupler 13 drives leading screw 11, and leading screw 11 drive moving contacts 7 move along axis direction and arrive service position or earthing position.Three-station can be reliably by operating current and short-circuit current when the service position, utilizing the insulating capacity of fracture that the needs maintenance or the circuit of segmentation and charged circuit are isolated mutually when the isolated location, is the safety in order to ensure the maintainer when earthing position.
