Diverse location is in, to realize that mechanical interlocking is relatively difficult, dead electricity or electric can not be protected in electric interlock using electric interlock
Interlocking effectively is accomplished to prevent maloperation in the case of breaking down, and if being to have enough keys using the not enough place of padlock interlocking
Spoon, then can entirely open the lock of all switch cubicles, so as to leave a variety of hidden danger of maloperation, it is impossible to which good protection switch is set
It is standby, or even have influence on higher level's current supply circuit.
Existing electric interlock effectively can not be accomplished to prevent maloperation in the case of dead electricity or failure;Padlock is interlocked
Then because the key of every lock is excessive, it is impossible to which fully achieving prevents the possibility of maloperation.
In view of this, nowadays in the urgent need to designing a kind of new interlocking gear, to overcome existing interlocking gear presence
Drawbacks described above.
Utility model content
Technical problem to be solved in the utility model is:A kind of High-voltage Incoming Cabinet, the interlocking of mother cabinet key mechanical are provided
Device, can effectively prevent the manually or electrically maloperation of High-voltage Incoming Cabinet and mother cabinet.
In order to solve the above technical problems, the utility model is adopted the following technical scheme that:
A kind of High-voltage Incoming Cabinet, mother cabinet key mechanical interlock, the mechanical interlocks include:Procedure lock, key
Spoon, procedure lock fixed plate, microswitch, programed interlocking plate;
Described program lock includes connecting rod, and connecting rod action is Direct Action Type;The key coordinates with procedure lock, and key is rotary
Action, the movement of connecting rod is locked by rotating control program;
Described program interlock plate is installed on the connecting rod of procedure lock, insertion operation axle when being moved during action to side, with reality
Existing interlock;
Described program locking fixed board plays support program lock and auxiliary switch, is installed on by the operating shaft on switching mechanism
Side;The microswitch plays instruction program lock operating position or electric interlock, is that 3 contacts one are opened one and closed;
When the on-load switch or disconnecting switch of high-tension switch cabinet or mother cabinet are in open position, the cam of microswitch
Being stressed makes normally opened closure, and normally opened contact is connected into mechanism controls loop;When switch is in mechanical interlocking in Interlock Status,
Microswitch is triggered, release mechanism control loop reaches electric interlock purpose;When switch is in mechanical interlocking state, switching on and shutting down
The electronic loop of structure will not close a floodgate because of maloperation.
The beneficial effects of the utility model are:The utility model proposes High-voltage Incoming Cabinet, mother cabinet key mechanical connection
Locking device, it is possible to achieve the mechanical interlocking between one group of switch cubicle mesohigh incoming line cabinet and mother cabinet, effectively can prevent height to be pressed into
The manually or electrically maloperation of line cabinet and mother cabinet;The auxiliary stroke provided with position instruction is switched in the present apparatus simultaneously, Ke Yiyong
In indicating loop or control loop, make the electric function of switch cubicle more reliable.

Embodiment
Describe preferred embodiment of the present utility model in detail below in conjunction with the accompanying drawings.
Embodiment one
Fig. 1, Fig. 2 are referred to, the utility model discloses a kind of High-voltage Incoming Cabinet, mother cabinet key mechanical interlock,
The mechanical interlocks includes:Procedure lock 1, key 2, procedure lock fixed plate 3, microswitch 4, programed interlocking plate 5.
Described program lock 1 includes connecting rod, and connecting rod action is Direct Action Type, and actuating length can be 14mm.The key 2 and journey
Sequence lock 1 coordinates, and key 2 (being private key) is rotary action, and the movement of 1 connecting rod is locked by rotating control program, enters the inverse time
Procedure lock connecting rod is moved forward during pin, and initial position is returned when clockwise.
Described program interlock plate 5 is installed on the connecting rod of procedure lock 1, insertion operation axle when being moved during action to side, with
Realize interlock.Procedure lock fixed plate 3 plays support program lock and auxiliary switch, is installed on the operating shaft on switching mechanism
Side, particular location can make the appropriate adjustments according to product type.Described 4 instruction program lock operating positions or electric of microswitch
Interlocking is acted on, and is that 3 contacts one are opened one and closed.
Referring to Fig. 3, mechanical interlocking principle:The on-load switch or disconnecting switch of high-tension switch cabinet or mother cabinet are in separating brake
During position, the key 2 on mechanical interlocks is rotated counterclockwise, makes the connecting rod in procedure lock 1 promote programed interlocking plate 5 to move to the left
Make, be inserted into the groove in the operating shaft of on-load switch or disconnecting switch Nei or before operating shaft, realize interlock, extract procedure lock
Key 2, completes operation;
Referring to Fig. 4, mechanical release principle:Key 2 is inserted into procedure lock 1, turn clockwise key 2, makes in procedure lock 1
Connecting rod pull programed interlocking plate 5 to act to the right, programed interlocking plate 5 is exited in the operating shaft of on-load switch or disconnecting switch
In groove or before operating shaft, unlocking function is realized, now because of procedure lock structure function, key 2 cannot extract procedure lock 1.
Electric interlock principle:It is micro- when the on-load switch or disconnecting switch of high-tension switch cabinet or mother cabinet are in open position
The cam of dynamic switch 4 is stressed and makes normally opened closure, normally opened contact is connected into mechanism controls loop, it is mechanical that rotation key 2 makes
When lock is in Interlock Status, microswitch is triggered, so that release mechanism control loop, reaches electric interlock purpose:Switch is in
During mechanical interlocking state, the electronic loop of switching mechanism will not also close a floodgate because of maloperation;
When mechanical interlocking is unlocked, the connecting rod in procedure lock 1 pulls programed interlocking plate 5 to act to the right, and programed interlocking plate 5 makes
The normally opened contact of microswitch 4 triggers closure signal, and now the electronic loop of switching mechanism can implement electric operating.
In summary, the utility model proposes High-voltage Incoming Cabinet, mother cabinet key mechanical interlock, it is possible to achieve one
Mechanical interlocking between group switch cubicle mesohigh incoming line cabinet and mother cabinet, can effectively prevent the manual of High-voltage Incoming Cabinet and mother cabinet
Or electronic maloperation;The auxiliary stroke provided with position instruction is switched in the present apparatus simultaneously, be can serve to indicate that loop or is controlled back
Road, makes the electric function of switch cubicle more reliable.
