Description
Technical field
What the present invention relates to is a kind of operator and ground cutter mechanical locking device of isolating switch, belongs to the electric equipment technical field.
Background technology
At present the operator of GN10 type isolating switch-ground cutter does not have locking device each other, therefore, is easy to produce misoperation in normal course of operation, i.e. the cutter operator of when closing a floodgate, closing again, perhaps operate when closing a floodgate, close again cutter.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, and provide a kind of simple in structure, easy for installation, can improve the locking reliability, with operator and the ground cutter mechanical locking device of the generator bus isolating switch that prevents from moving misoperation.
The objective of the invention is to finish by following technical solution, it is included in operator rotating shaft and ground swivel axle on the isolating switch, be connected with respectively a poke rod and a locking cover on described operator rotating shaft and the ground swivel axle, the poke rod in the rotating shaft of wherein operating is connected in operator draw key in the locking cover that links to each other on the swivel axle insertedly by one group of linkage; And the poke rod on the described ground swivel axle also is connected in a ground cutter draw key that can insert in the locking cover that links to each other in the operator rotating shaft by one group of linkage.
Described one group of linkage mainly by a drive link that links to each other with pin with poke rod with the leading section kinematic link that draw key, rearward end be connected a swing arm of ining succession mutually and forms, the centre of described swing arm is fixed with pin, and two ends are connection for transmission bar and kinematic link respectively.
The present invention can realize easily operating and ground swivel axle between mutual locking, reach isolated switch main, the locking effect between the cutter, have simple in structurely, easy for installation, can improve the characteristics such as locking reliability.
Description of drawings
Fig. 1 is the Facad structure schematic diagram of isolating switch mechanical locking device of the present invention.
Fig. 2 is the side structure schematic diagram of isolating switch mechanical locking device of the present invention.
Embodiment
The present invention will be described in detail below in conjunction with accompanying drawing: shown in Fig. 1,2, the operator of generator bus isolating switch of the present invention and ground cutter mechanical locking device, it is included in operator rotating shaft 1 and ground swivel axle 2 on the isolating switch, be connected with respectively a poke rod 3 and a locking cover 4 on described operator rotating shaft 1 and the ground swivel axle 2, the poke rod 3 in the rotating shaft 1 of wherein operating is connected in operator draw key 5 in the locking cover 4 that links to each other on the swivel axle 2 insertedly by one group of linkage; And the poke rod 3 on the described ground swivel axle 2 also is connected in a ground cutter draw key 5 that can insert in the locking cover 4 that links to each other in the operator rotating shaft 1 by one group of linkage; Be that described operator is identical with the structure of ground cutter.
Described one group of linkage mainly by a drive link 7 that links to each other with poke rod 3 usefulness pins 6 with the leading section kinematic link 9 that draw key 5, rearward end be connected a swing arm 8 of ining succession mutually and forms, fixing with pin 10 in the middle of the described swing arm 8, two ends are connection for transmission bar 7 and kinematic link 9 respectively.
Because the master of isolating switch, cutter driven by operator rotating shaft 1 and ground swivel axle 2 respectively in the breaking-closing operating process, namely rotate 90 when spending (operator of isolating switch is example) when rotating shaft of operation, then the isolating switch operator realize from the gate-dividing state to the "on" position or the plug-in strip operator from the "on" position to the gate-dividing state.Realize the operator of isolating switch and the mutual locking between the ground cutter, the rotation locking of then controlling between these two operating axis is just passable.
Isolated switch main of the present invention, between the cutter main thought of locking be: when operator and ground cutter during simultaneously at separating brake, then operating rotating shaft and ground swivel axle all can be at the free operant state; Local cutter is when closing a floodgate, and the rotating shaft of then operating is blocked, and can not be operated; Equally, when operating at closing position, then the swivel axle is blocked, and can not be operated.Reach this purpose and just can realize mutual locking between isolating switch operator and the ground cutter, can exempt to move misoperation.
Embodiment:
Among Fig. 1,2, C, D are rotating shaft, be enclosed within the plug-in strip master, on the swivel axle and fixing.The structure of rotating shaft is double-deck sleeve, can freely rotate between two axle sleeves, is to adopt the stainless steel roller bearing to be connected to be integral.The rotating shaft of internal axle sleeve and plug-in strip is fixed, and rotates with the plug-in strip rotating shaft, and outer relatively internal layer is fixed.
Shown in the figure: pin 6 is to be fixed on the internal layer axle sleeve, rotates with rotating shaft, the top 90 that represents among range of movement such as the figure
0
The motion conditions of drive link 7 and kinematic link 9 transmission rotating shafts, its length can change;
The expression of E place: whole locking device divides two lobes independently to process, and adopts the stainless steel connecting rod of three Φ 20 to link into an integrated entity after the processing.Its objective is as being fit to the locked with shaft of different spacing.
Isolated switch main, cutter locking overall process explanation:
Such as rotating shaft (master of isolating switch, cutter during all at separating brake) when Fig. 2 state, rotating shaft C, D can freely rotate, when rotating shaft C is rotated toward the rotation of combined floodgate direction, pin 6 is turned left, pulling drive link 7 makes kinematic link 9 motion of turning right, and kinematic link 9 promotes draw keys 5 lock ingots and inserts locking to the right and overlap in 4, at this moment rotating shaft D is lockable, and can not be operated.In like manner, when C axle during at sub-gate position, D axially closes a floodgate direction when rotating, and also can reliably pin the C axle.
