Background technology:
The gas-insulated metal switchgear is isolated by metal shell and extraneous air, and section is filled with the sulphur hexafluoride insulating gas of certain pressure within it.The effect of isolating switch is to support to cut-off no-load current.Isolating switch cut-off power resources in the action bars that connects the housing inside and outside, this action bars links to each other with the outside link gearing, link gearing is connected with powered device device output shaft.The output shaft output torque of operator is delivered to the action bars that connects the housing inside and outside to moment by link gearing like this, and the action bars action drives the isolating switch internal part and carries out the divide-shut brake action.Thereby reach the purpose of cut-offfing no-load current.
Link gearing such as Fig. 3 of the divide-shut brake action of present gas insulation metal seal combined electrical apparatus (being called for short GIS) isolating switch, shown in Figure 4, whole link gearing comprises the drive link 5 that is connected with operator 12 output shafts, drive link 5 is connected with first connecting rod 6 by pin, first connecting rod 6 opposite sides are connected with shift fork 9 one side fixing holes, shift fork 9 opposite side fixing holes connect a side of second connecting rod 10, the opposite side of second connecting rod 10 is connected to a side of third connecting rod 11, the opposite side of third connecting rod 11 is connected to the action bars that isolating switch 13 connects the housing inside and outside, such as Fig. 4.Shift fork 9 is fixed on the first fixed support 7, and the first fixed support 7 is fixed on the housing maintenance blind flange by the second fixed support 8, by shift fork 9 moment is delivered on the second connecting rod 10 from first connecting rod 6.
The link gearing of this kind structure need to be flexibly connected point by one group of drive link 5 and first connecting rod 6, second connecting rod 10 and third connecting rod 11 and four and finish, and transmitted power is low.Between first connecting rod 6 and second connecting rod 10, need add the first fixed support 7 and the second fixed support 8, moment screens phenomenon when driving torque, can occur, make in time opening and closing in place of isolating switch.
In addition, fixed support 8 is fixed on the maintenance blind flange, need to pull down this support during maintenance, because the shift in position of the second fixed support 8 and the first fixed support 7, cause also change of connecting rod position, must readjust deciliter position of isolating switch again after having overhauled, this brings difficulty to maintenance.
The utility model content:
The utility model provides a kind of link gearing of GIS isolating switch divide-shut brake action, and it is simple in structure, and the moment transmitted power is high, and easy access has solved problems of the prior art.
The utility model is to solve the problems of the technologies described above the technical scheme that adopts to be:
A kind of link gearing of GIS isolating switch divide-shut brake action, comprise operator, link gearing, action bars and isolating switch, the output shaft of link gearing one end attended operation device, the other end connects the action bars that is positioned at isolating switch housing inside and outside, it is characterized in that, described link gearing comprises the drive link that is connected with the operator output shaft, described drive link is connected with the A connecting rod by the first universal spindle nose, the opposite side of described A connecting rod connects the B connecting rod by the second universal spindle nose, the opposite side of described B connecting rod is connected on the action bars of isolating switch connection housing inside and outside, and B connecting rod middle part is provided with rotating fulcrum near a side of action bars.
Described drive link clockwise turns to "on" position, is rotated counterclockwise to be gate-dividing state.
The beneficial effects of the utility model are:
1, whole link gearing is only just finished by one group of drive link and two groups of connecting rods and two movable points of contact, and it is simple in structure, has improved the moment transmitted power.
2, whole link gearing does not relate to fixed support, moment screens phenomenon can not occur, and takes full advantage of the large characteristics of universal spindle nose transmitting torque.
3, maintenance does not relate to link gearing during isolating switch, need not to readjust the divide-shut brake position of isolating switch, to the site examining and repairing condition that facilitates.
