Description
Technical field
The utility model relates to the mechanical interlocks between a kind of high voltage isolator and the high voltage ground switch.
Background technology
High voltage isolator is to require when separating brake, the insulation distance of requirement up to specification is arranged between contact and obviously disconnect sign; When closing position, can carry the switchgear of the electric current under the exceptional condition in electric current under the normal loop condition and stipulated time.High voltage ground switch then is a kind of mechanical device that is used for loop ground connection, and it can carry the electric current under the exceptional condition in the stipulated time, does not then require loaded current during normal loop.Interlock is must depend on other positions or operating means when making switchgear operation.Requirement must be provided with mechanical interlocks between power high voltage switchgear isolating switch and the earthed switch.Be high voltage isolator when being in closing position, earthed switch can't close a floodgate, and is in gate-dividing state; When high voltage isolator was in gate-dividing state, earthed switch must be in "on" position.It mainly is in order to prevent the misoperation of earthed switch, the generation of prevention peril that this set requires.Present mechanical interlocks complex structure, transmission process is loaded down with trivial details, the cost height.
Summary of the invention
The utility model provides a kind of simple and reasonable for structure in order to overcome above-mentioned defective, and transmission is stable, simple and reliable mechanical interlocks.
The technical solution adopted in the utility model is: the mechanical interlocks between a kind of high voltage isolator and the high voltage ground switch, comprise connecting lever, win in succession, joint, connecting rod, bent plate, holder and fairlead, described connecting lever vertical fixing is connected on the main shaft of isolating switch, the connecting lever other end and connecting plate are articulated and connected, the other end and the joint of connecting plate are articulated and connected, the other end of joint and connecting rod are for being threaded, holder is fixedly connected on the base, fairlead is set on the holder, fairlead is passed at the middle part of described connecting rod, and its front end reaches that side of earthed switch; Be fixedly connected with bent plate on the bottom of moving contact conducting rod, earthed switch main shaft, bent plate is the perpendicular corners shape, and the front end of described connecting rod is against the bent plate outside.
The utility model is provided with connecting lever on the main shaft of isolating switch, connecting lever and connecting plate, connecting plate and joint are and are articulated and connected, joint is connected with connecting rod, connecting rod passes its front end of back in the fairlead and extend into that side of earthed switch, like this, the isolating switch main shaft to rotatablely move by connecting lever and connecting plate and joint drivening rod be rectilinear motion, simultaneously, in bottom at the moving contact conducting rod, be provided with the bent plate of perpendicular corners shape on the earthed switch main shaft, the front end of connecting rod is against the bent plate outside, thereby the isolating switch main shaft rotates drivening rod and moves, and connecting rod is because connecting plate, the spacing relation of holder and fairlead, can only folk prescription to moving linearly, thereby the position restricting relation between dependence connecting rod and the bent plate is realized the interlocking of isolating switch and earthed switch, make promptly no matter earthed switch is closing a floodgate still under gate-dividing state, the capital is subjected to the spacing of connecting rod, also just realized that by whole interlock earthed switch isolating switch under certain state can not move simultaneously, effectively prevent the misoperation of earthed switch, the generation of prevention peril.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model.
Embodiment
Now in conjunction with the accompanying drawings the utility model is further described, Fig. 1 is a kind of embodiment of the present utility model, comprise connecting lever 2, win in succession, joint 3, connecting rod 5, bent plate 8, holder 6 and fairlead 7, described connecting lever 2 vertical fixing are connected on the isolating switch main shaft 1, connecting lever 2 other ends and connecting plate 2 are articulated and connected, the other end of connecting plate 2 and joint 3 are articulated and connected, and the other end of joint 3 and connecting rod 5 are for being threaded.Holder 6 is fixedly connected on the base, and fairlead 7 is set on the holder 6, and fairlead 7 is passed at the middle part of described connecting rod 5, and its front end reaches earthed switch 10 those sides.Be fixedly connected with bent plate 8 on the bottom of moving contact conducting rod, earthed switch main shaft 9, bent plate 8 is the perpendicular corners shape, and one of them right-angle side is connected with conducting rod is vertical, and the front end of described connecting rod 5 is against the outside that bent plate 8 is the right-angle side of vertical shape.The utility model is set to joint 3 to be threaded with connecting rod 5, can regulate the length of connecting rod 5 as required, makes connecting rod 5 be close proximity to bent plate 8 outsides.
Be that 1 pair of operating state of the present utility model of embodiment is further described when now being "on" position with isolating switch 11, see Fig. 1: isolating switch 11 requires during for "on" position earthed switch 10 to be gate-dividing state.During isolating switch 11 "on" positions, the connecting lever 2 that is connected with isolating switch main shaft 1 is connected with connecting rod 5 by connecting plate 2, joint 3, connect and pass the bent plate 8 that fairlead 7 stretches to earthed switch 10 those sides, at this moment, earthed switch 10 is a gate-dividing state, and promptly conducting rod is horizontal, be vertical shape with that right-angle side of conducting rod bent plate 8 connected vertically, another right-angle side of bent plate 8 is horizontal, and stretches to earthed switch 10 those sides, promptly stretches to that side away from connecting rod 5.At this moment, the front end of described connecting rod 5 just abuts against the outside of the right-angle side that is connected with conducting rod, the outside that promptly is the right-angle side of vertical shape, also withstand on the right-angle side outside of this bent plate 8, conducting rod has been carried out spacing, prevent its action just because of connecting rod 5, thereby when having realized that isolating switch 11 is in closing position, earthed switch 10 can't close a floodgate, and effectively prevents the misoperation of earthed switch 10, the generation of prevention peril.
Fig. 2 is the utility model embodiment 2, and isolating switch 11 is a gate-dividing state among the embodiment 2.When needs close a floodgate earthed switch 10, earlier isolating switch 11 is carried out the separating brake action, isolating switch main shaft 1 rotation drive connecting lever 2 rotates up behind isolating switch 11 separating brakes, connecting lever 2 is by connecting plate 2, joint 3 pulling connecting rods 5 move backward, connecting rod 5 just leaves bent plate 8 certain distances, at this moment, the conducting rod of earthed switch 10 just can carry out feed motion, after the conducting rod of earthed switch 10 closes a floodgate, that right-angle side of the bent plate 8 that is connected with the conducting rod bottom is horizontal, another right-angle side of bent plate 8 is vertical shape, and this moment, connecting rod 5 just is close proximity to the outside of the right-angle side of the bent plate 8 that is vertical shape again, connecting rod 5 has just carried out spacing to conducting rod again like this, prevent its action, when isolating switch 11 was in gate-dividing state, earthed switch 10 must be in "on" position.Thereby realized the safety guarantee effect of interlock.
This shows, the utlity model has simple and reasonable for structure, stable, the easy characteristics such as reliable of transmission.
