Abstract
The utility model discloses an interlocking mechanism of the main switch and grounding shaft of the grounding isolating switch used in electricity power distribution system. The technical proposal of the utility model is that the main shaft(2) of the switch is provided with a fan type vacuum groove board(3); the grounding rotating shaft(6) of the switch is provided with an interlocking lever(5); a pin ram(4) is articulately connected between the fan type vacuum groove board(3) and the interlocking lever(5). The utility model makes the main shaft(2) of the switch and the grounding rotating shaft(6) of the switch only stay in state of opening both or one opening and the other closing, which is able to completely prevent the accidents which is caused by the mistake closing of the switch. The utility model has the advantage of simple and compact structure.
Description
Technical field
The utility model relates to a kind of power distribution isolating switch, and is relevant with grounding shaft interlocking device with the isolating switch main shaft of band ground connection especially.Belong to electrical technology field.
Background technology
The isolating switch of high pressure belt ground connection is the device of getting in touch of isolating, connect, change electrified body and electric device in the electrical power distribution system under the non-loaded state of circuit, wherein the grounded part with the isolating switch of ground connection is when isolating switch is isolated distribution system, grounded part is connected, make whole distribution system ground connection, thereby absolute guarantee to safeguard or workman's safety during construction.The isolating switch of present band ground connection, its main shaft and grounding shaft are normally operated respectively with two cover operating mechanisms.For prevent that isolating switch main shaft and earthed switch grounding shaft from closing by mistake, two operating mechanisms of actuating isolating switch main shaft and grounding shaft need add electric interlocking, and structure is very complicated, and accident happens occasionally, and effect is not very good.
The utility model content
The purpose of this utility model is that a kind of structure of design is more simply with the mechanism of the isolating switch main shaft and the grounding shaft reciprocal interlocking of ground connection.
The technical solution of the utility model is such, sets up a fan type hollow channel boards on switch spindle, sets up an interlocking connecting lever on the switch grounding shaft, a hinged connecting rod between fan type hollow channel boards and the interlocking connecting lever.
Band earthing isolator main shaft that the utility model provides and grounding shaft link gear, when switch spindle was in combined floodgate, band pin connecting rod one end was in fan type hollow channel boards end, and the switch grounding shaft is in separating brake position, akinesia; When switch spindle was rotated, band pin connecting rod one end was in the middle groove of fan type hollow channel boards, does the slippage action.Switch spindle is rotated when motion puts in place fully, switch spindle is in the separating brake position, fan type hollow channel boards is reserved one section space, actuating connecting lever on the actuating this moment grounding shaft carries out grounding shaft and closes a floodgate, the actuating connecting lever drives interlocking connecting lever rotation on the grounding shaft, the interlocking connecting lever drives pin connecting rod one end again and rotates, and the band pin connecting rod other end moves in the groove in the middle of the fan type hollow channel boards, to realize the feed motion of switch grounding shaft.The switch grounding shaft rotates when motion puts in place fully, and band pin connecting rod one end moves to fan type hollow channel boards end again, and switch spindle is in separating brake position, akinesia.
The band earthing isolator main shaft that the utility model provides and the mechanism of grounding shaft reciprocal interlocking can prevent definitely that switch from closing the accident that produces because of mistake and taking place, and be simple in structure, compact.
Description of drawings
Fig. 1 is existing band earthing isolator operating mechanism schematic diagram;
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, actuating connecting lever 2, switch spindle 3, fan type hollow channel boards 4, band pin connecting rod 5, interlocking connecting lever 6, switch ground connection rotating shaft 7, actuating connecting lever
As shown in Figure 2, actuating connecting lever 1 and fan type hollow channel boards 3 are housed respectively on switch spindle 2, actuating connecting lever 7 and interlocking connecting lever 5 are housed respectively in the switch ground connection rotating shaft 6, between fan type hollow channel boards 3 and interlocking connecting lever 5, be hinged with band pin connecting rod 4.
When switch spindle 2 was in combined floodgate, band pin connecting rod 4 one ends were in fan type hollow channel boards 3 ends, and switch grounding shaft 6 is in separating brake position, akinesia; When the actuating connecting lever 1 on the actuating switch spindle 2, when switch spindle 2 was rotated, band pin connecting rod 4 one ends were in the groove in the middle of the fan type hollow channel boards 3, do to draw to move and do.Switch spindle 2 is rotated when motion puts in place fully, switch spindle 2 is in the separating brake position, fan type hollow channel boards 3 is reserved one section space, actuating connecting lever 7 on the actuating this moment grounding shaft closes a floodgate, actuating connecting lever 7 drives interlocking connecting lever 5 rotations on the grounding shaft 6, interlocking connecting lever 5 drives pin connecting rod 4 one ends again and rotates, and moves in the groove of band pin connecting rod 4 other ends in the middle of fan type hollow channel boards 3, to realize the feed motion of switch grounding shaft 6.Switch grounding shaft 6 rotates when motion puts in place fully, and band pin connecting rod 4 one ends move to fan type hollow channel boards 3 ends again, and switch spindle 2 is in separating brake position, akinesia.Like this, switch spindle 2 and switch grounding shaft 6 can only be in time-division or the state that closed in one minute one, prevent misoperation.
