Abstract
The utility model discloses an interlocking mechanism of a disconnector and a grounding switch. The operation shaft (4) of the disconnector (1) is fixedly connected with a cam (3). The operation shaft (6) of the grounding switch (8) is fixedly connected with a concave wheel (7). A movable wheel (5) which can move up and down is arranged between the cam (3) and the concave wheel (7). The movable wheel (5) is arranged on a guide rod (2) fixed on a switch cabinet. The utility model has reliable interlocking and convenient operation, can not cause misoperation and can prevent safety accident effectively.
Description
Technical field
The utility model relates to a kind of isolating switch in the electrical power distribution system switchgear and the interlocking device of earthed switch.
Background technology
In 6kV and 10kV medium voltage electricity power transmission and transformation system switch cubicle, when disconnecting switch operation and earthed switch, main control artificially isolating switch and earthed switch deciliter, only under the isolating switch gate-dividing state, could overhaul by splice grafting ground switch under the normal condition.At present, isolating switch and earthed switch be interlocking not, if the operation earthed switch closes a floodgate under the isolating switch "on" position, misoperation will occur, can cause personal injury or other more serious accident.
The utility model content
The purpose of this utility model is exactly the interlocking device of a kind of isolating switch of design and earthed switch.
The technical solution of the utility model is: the interlocking device of a kind of isolating switch and earthed switch, on the operating axis of isolating switch, fix a cam, on the operating axis of earthed switch, fix recessed a wheel, be provided with between cam and recessed the wheel can be up and down activity wheel, movable wheel is installed on the guide post that is fixed on the switch cubicle.
The isolating switch that the utility model provides and the interlocking device of earthed switch install in the switch cubicle, by up and down isolating switch and the earthed switch operating sequence of realizing of activity wheel, realize isolating switch and earthed switch deciliter.Under the charged situation of switch cubicle, isolating switch is in "on" position, and the interlocking of earthed switch this moment by movable wheel is in gate-dividing state and can not closes a floodgate.Under inspection switch cabinet situation, the isolating switch separating brake, movable wheel is removed the earthed switch interlocking, and earthed switch can close a floodgate smoothly, can overhaul.After maintenance finished, this moment, isolating switch can not close a floodgate by the interlocking of activity wheel, have only divide the ground connection switch earlier after, interlocking is removed, isolating switch closes a floodgate, and realizes safe power supply.The interlock interlocking of this isolating switch and earthed switch is reliable, easy to operate, can not cause misoperation, can effectively prevent the generation of security incident.
Description of drawings
Fig. 1 is the left TV structure schematic diagram of the utility model isolating switch and the embodiment of earthed switch interlocking device;
Fig. 2 is in gate-dividing state for the utility model isolating switch and earthed switch interlocking device the foregoing description at isolating switch, the structural representation when earthed switch is in "on" position;
Fig. 3 is in "on" position for the utility model isolating switch and earthed switch interlocking device the foregoing description at isolating switch, the structural representation when earthed switch is in gate-dividing state.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
Among the figure: 1, isolating switch 2, guide post 3, cam 4, isolator operation axle 5, movable wheel 6, earthed switch operating axis 7, recessedly take turns 8, earthed switch
As shown in the figure, a cam 3 is fixed by the interlocking device of the utility model isolating switch and earthed switch on the operating axis 4 of isolating switch 1, on the operating axis 6 of earthed switch 8, fix one and recessedly take turns 7, cam 3 and recessed take turns 7 be provided with can be up and down activity wheel 5, movable wheel 5 is installed on the guide post 2 that is fixed on the switch cubicle.
Under normal maintenance situation, isolating switch 1 is in gate-dividing state, and earthed switch 8 is in "on" position, as shown in Figure 2, this moment, movable wheel 5 upwards slided into the concave surface place of cam 3, because movable wheel 5 is spacing, cause cam 3 not clockwise rotate, isolating switch 1 can not close a floodgate again.At this moment can safety inspection.After maintenance finishes, counterclockwise operational grounding switching manipulation axle 6, drive and recessedly take turns 7 and earthed switch 8, make the earthed switch separating brake, to sub-gate position postpone, movable wheel 5 is slipped to recessed the wheel in 7 the groove downwards, and as shown in Figure 3,5 pairs of cams of movable wheel this moment, 3 interlockings are removed, disconnecting switch operation operating axis 4 drive cams 3 and isolating switch 1 close a floodgate isolating switch 1 clockwise, this moment, earthed switch 8 was in the separating brake position, and movable wheel 5 is taken turns in 7 the groove, because cam 3 is spacing recessed, movable wheel 5 can not be moved up and down, can not allow earthed switch 8 close a floodgate by operational grounding switching manipulation axle 6, form interlocking reliably, can prevent misoperation.
The isolating switch that the utility model provides and the interlocking device of earthed switch are installed in the high-voltage switch gear cabinets such as 6kV, 10kV, when repair and maintenance, can not cause misoperation, and easy to operate, safe and reliable.
Claims (1)
1. the interlocking device of isolating switch and earthed switch, it is characterized in that: on the operating axis (4) of isolating switch (1), be fixed with a cam (3), on the operating axis (6) of earthed switch (8), be fixed with recessed a wheel (7), be provided with between cam (3) and recessed wheel the (7) can be up and down activity wheel (5), movable wheel (5) is installed on the guide post (2) that is fixed on the switch cubicle.
