Abstract
The utility model discloses a main shaft of grounding isolation switch and grounding shaft linkage mechanism of high-voltage zone in power distribution system. The mechanism is provided with a connecting lever (3) and a connecting lever (5) respectively on non-operated side of a switch spindle (2) and a switch grounding shaft (6), the connecting lever (3) and connecting lever (5) are connected each other in the middle by a linking rod(4), an operating mechanism (7) and a connecting lever (1) is hinged by a pin with hole. When operating mechanism(7) regulates the connecting lever (1), the switch spindle (2) and the connecting lever (3) are driven for circular movement, and further the connecting lever (5) is rotated through the linking rod (4). Thus, when isolating switch spindle (2) is switched on or off, the grounding axis (6) is also switched on or off. The device is in simple and compact structure, and has absolutely prevent multifunction of the isolation switch and the grounding switch.
Description
Technical field
The utility model belongs to electrical technology field, particularly a kind of main shaft of high pressure belt earthing isolator and grounding shaft link gear.
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 that grounded part is connected, and makes whole distribution system ground connection when isolating switch is isolated distribution system, thus the absolute safety that guarantees maintenance or workmen.The isolating switch of existing band ground connection, its main shaft 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 making of design uses an operating mechanism operation simultaneously, can prevent that the switch mistake from closing or the main shaft and the grounding shaft link gear of the high pressure belt earthing isolator that mistake is divided.
The utility model is achieved in that the interlock connecting lever is housed respectively on the main shaft of switch main body and grounding shaft, with pin with split pin hole connecting rod and two interlock connecting levers is linked together.Switch spindle also is provided with the actuating connecting lever, and during operating mechanism operation axis actuating connecting lever, main shaft drives the interlock connecting lever, drives the action of grounding shaft interlock connecting lever by connecting rod, and when switch spindle was divided fully or is incorporated into, grounding shaft just closed or divides and put in place.
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, when being operating mechanism disconnecting switch operation main shaft separating brake or combined floodgate, the isolating switch grounding shaft is closed a floodgate or separating brake, simple in structure, compact, prevented that definitely the mistake of switch from dividing mistake to close.
Description of drawings
Fig. 1 is the structural representation of existing band earthing isolator main shaft and grounding shaft operating mechanism;
Fig. 2 is the main shaft of the utility model band earthing isolator and the structural representation of an embodiment of grounding shaft link gear.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
Among the figure: 1, operation connecting lever 2, switch spindle 3, interlock connecting lever 4, connecting rod 5, interlock connecting lever 6, switch ground connection rotating shaft 7, operating mechanism
In the embodiment shown in Figure 2, operation connecting lever 1 is arranged on the fore side of switch spindle 2, and interlock connecting lever 3 and interlock connecting lever 5 are contained in the not operation side of switch spindle 2 and switch ground connection rotating shaft 6 respectively, connects by connecting rod 4 in the middle of the two interlock connecting levers.Operating mechanism 7 and operation connecting lever 1 usefulness pin with split pin hole are hinged.When operating mechanism 7 actuatings operations connecting lever 1, the interlock connecting lever 3 that operation connecting lever 1 drives switch spindle 2 and is contained in switch spindle 2 not operation sides moves in a circle.Interlock connecting lever 3 rotates by the interlock connecting lever 5 that connecting rod 4 drives grounding shaft 6 not operation sides.When isolating switch main shaft 2 separating brakes or combined floodgate put in place, grounding shaft 6 motions are closed a floodgate or separating brake puts in place.
Claims (1)
- A kind of main shaft of high pressure belt earthing isolator and grounding shaft link gear, comprise operation connecting lever (1), switch spindle (2), switch ground connection rotating shaft (6) and operating mechanism (7), it is characterized in that: the not operation side in switch spindle (2) and switch ground connection rotating shaft (6) is respectively arranged with interlock connecting lever (3) and interlock connecting lever (5), interlock connecting lever (3) is connected by connecting rod (4) with interlock connecting lever (5) is middle, and operating mechanism (7) and operation connecting lever (1) are hinged by pin with split pin hole.
