Abstract
The utility model discloses a linking mechanism of axle of the disconnected switch with grounding and grounding axle in the power distribution system. The system is on the switch shaft (2) and switch grounding shaft (11), equipped with lever (3) and lever (9) respectively. A intermediate shaft(10) is clung to the frame of the switch in the shape of the Chinese character Hui , and the curved plate(7) and the operational lever(4) are together equipped on the intermediate shaft(10). Fastening bolt (5) and washer (6) limit the axis direction of the operational lever (4) and the curved plate (7) within the intermediate shaft (10). The operational mechanism (8) and operational lever (4) are hinged together with the pin with hole. Lever (3) and lever (9) are connected with curved plate (7) with two slotted pins. This linking mechanism makes axle and grounding axle use the same operational mechanism at the same time, which can prevent the false switch on/off to avoid accidents with the simple and compact structure.
Description
Technical field
The utility model belongs to electrical technology field, relates to a kind of isolating switch main shaft and grounding shaft link gear with ground connection.
Background technology
The isolating switch of high pressure belt ground connection is the device that isolation under the non-loaded state of circuit, connection, conversion electrified body and electric device are got in touch in the electrical power distribution system, its grounded part is when isolating switch is isolated distribution system, grounded part is connected, make whole distribution system ground connection, thereby absolute guarantee to safeguard or staff's safety during construction.The isolating switch of the present band ground connection of using always, the main shaft of isolating switch and grounding shaft are normally operated respectively with two cover operating mechanisms.Divide for preventing that isolating switch and earthed switch mistake from closing by mistake, isolating switch main shaft and grounding shaft need add mechanical interlocking or electrical interlock, and structure is very complicated, and effect is not very good yet.
The utility model content
The purpose of this utility model is that a kind of main shaft and grounding shaft of can making of design uses an operating mechanism operation simultaneously, closes band earthing isolator main shaft and the grounding shaft link gear that mistake is divided to prevent the switch mistake.
The utility model is achieved in that on the main shaft of switch main body and the grounding shaft connecting lever is housed respectively, and the type tank bracket that returns of switch main body tightens an intrinsic jack shaft, and curve ruler cooperates with a tongue and groove of operating on the connecting lever by own tongue and groove.Fastening bolt and packing ring are spacing on jack shaft with curve ruler and operation connecting lever, and the connecting lever in two rotating shafts is hinged by pin with split pin hole and curve ruler, operating mechanism by pin with split pin hole with to operate connecting lever hinged.When the actuating operating mechanism, drive the motion of operation connecting lever, the actuating connecting lever drives the curve ruler motion by tongue and groove, and the curve frid drives isolating switch main shaft connecting lever branch by own curved groove by pin with split pin hole or closes, and grounding shaft connecting lever pin with split pin hole is slided in the curve frid.When switch spindle was divided fully or is incorporated into, grounding shaft place curve frid just moved and puts in place, places restrictions on ground connection connecting lever pin with split pin hole, and the ground connection connecting lever begins to rotate, thereby drove grounding shaft separating brake or combined floodgate.
Band earthing isolator main shaft that the utility model provides and grounding shaft link gear, make main shaft and grounding shaft use an operating mechanism operation simultaneously, after being operating mechanism disconnecting switch operation main shaft separating brake or combined floodgate, continue the same operating mechanism of operation, the isolating switch grounding shaft is closed a floodgate or separating brake.The mistake that can definitely prevent switch divides mistake to close, and avoids accident to take place, and is simple in structure, compact.
Description of drawings
Fig. 1 is the structural representation of prior art band earthing isolator operating mechanism;
Fig. 2 is the structural representation of a utility model band earthing isolator main shaft and an embodiment of grounding shaft link gear.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, return type framework 2, main shaft 3, connecting lever 4, operation connecting lever 5, bolt 6, packing ring 7, curve frid 8, mechanism 9, connecting lever 10, jack shaft 11, ground connection rotating shaft
In the embodiment shown in Figure 2, connecting lever 3, connecting lever 9 are contained in respectively in switch spindle 2 and the switch ground connection rotating shaft 11, and switch returns type framework 1 and tightens intrinsic jack shaft 10, and curve frid 7 and 4 cooperations of operation connecting lever are installed on the jack shaft 10.Fastening bolt 5 and packing ring 6 with actuating connecting lever 4 and curve frid 7 axial limitings on jack shaft 10.Operating mechanism 8 and actuating connecting lever 4 usefulness pin with split pin holes are hinged.Connecting lever 3 and connecting lever 9 are connected with curve frid 7 by two pins with groove.When operating mechanism 8 actuatings operation connecting lever 4, actuating connecting lever 4 drives curve frid 7, curve frid 7 is moved in a circle around jack shaft 10, drive switch spindle connecting lever 3 rotating switch connecting levers 3 and drive main shaft 2 rotations, switch grounding shaft connecting lever 9 slides in curve frid 7 simultaneously, does not drive grounding shaft 11 and rotates.When 2 motions of isolating switch main shaft put in place, 3 beginnings of isolating switch main shaft connecting lever were slided in curve frid 7, drove switch grounding shaft connecting lever 9 and moved in a circle, thereby drive grounding shaft 11 motion separating brake or combined floodgates.This band earthing isolator main shaft and grounding shaft link gear, make main shaft 2 and ground connection rotating shaft 11 use an operating mechanism operation simultaneously, after being operating mechanism disconnecting switch operation main shaft 2 separating brakes or combined floodgate, continue the same operating mechanism of operation, isolating switch ground connection rotating shaft 11 is closed a floodgate or separating brakes.The mistake that can definitely prevent switch divides mistake to close, and avoids accident to take place, and is simple in structure, compact.
