Description
Technical field
The utility model relates to a kind of incorrect operation preventing interlocking apparatus for permanent magnetic vacuum breaker.
Background technology
The electric misoperation of high-voltage switch gear, easily causes power equipment damage, system blackout, the accident such as casualties even.But the interlocking device of existing handcart-type permanent magnetic vacuum breaker realizes by electrical equipment control mode, if electric elements damage or line fault easily causes accident, when circuit breaker cart is in test/isolation, service position, and circuit breaker is when "on" position, circuit breaker cart can not shake into, shake out operation; When circuit breaker is in gate-dividing state, and circuit breaker cart is in non-test/isolation, service position, and during any position in the middle of, circuit breaker can not carry out closing by hand, electric switch-on operation.The interlock of existing permanent magnetic vacuum breaker, shakes into the process of shaking out at chassis vehicle, if electrical equipment interlocking damages, circuit breaker can also close a floodgate.
Utility model content
The technical problems to be solved in the utility model is the defect that overcomes prior art, and a kind of incorrect operation preventing interlocking apparatus for permanent magnetic vacuum breaker is provided.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of incorrect operation preventing interlocking apparatus for permanent magnetic vacuum breaker of the utility model, comprises chassis vehicle interlock plate, interlocking bent plate, connecting plate, the sincere son of interlocking, drive rod, divide-shut brake bearing pin; Described chassis vehicle interlock plate one end is connected with the rotating shaft on chassis vehicle, and the other end is connected with described interlocking bent plate; The sincere son of described interlocking is fixed on mounting panel by pin, can rotate around pin; Described connecting plate all adopts rotatable pin to be connected with described interlocking bent plate with the sincere son of described interlocking.
When circuit breaker is in test or service position, and circuit breaker is when closing a floodgate, and divide-shut brake bearing pin and permanent magnet mechanism drive rod move downward, and interlocking bent plate and the sincere son of interlocking are depressed, and interlock plate can not rotate, and chassis vehicle is lockable, and chassis vehicle can not shake into shaking out.When circuit breaker is in gate-dividing state, chassis vehicle is shaking in the process of shaking out, and chassis vehicle spring is upspring, interlock plate rotates, interlocking bent plate and the sincere sub-jack-up of interlocking, if now closed a floodgate, divide-shut brake bearing pin and permanent magnet mechanism drive rod can not move downward, and are withstood, and can not close a floodgate.Thereby realize the interlock of circuit breaker operation mechanism and chassis vehicle.
The beneficial effect that the utility model reaches is:
1. simple in structure, utilize simple linkage, part processing is simple, and each part connects with bearing pin, easy installation and removal;
2. utility model can realize the chiasma interference of two places, only has a place to interfere compare, make performance more reliable with other interlocking devices, reduces misoperation probability;
3. on the basis of electrical equipment interlocking, increase mechanical interlocking, make the interlock of operating mechanism and chassis vehicle have many-sided assurance;
4. driving channel is not subject to the restriction of locking part locus and installation site, thereby avoids affecting other drive disk assembly motion.
Accompanying drawing explanation
Accompanying drawing is used to provide further understanding of the present utility model, and forms a part for specification, is used from explanation the utility model with embodiment mono-of the present utility model, does not form restriction of the present utility model.In the accompanying drawings:
Fig. 1 is circuit breaker structural representation of the present utility model can divide-shut brake time;
Fig. 2 is the right TV structure schematic diagram of Fig. 1;
Fig. 3 is circuit breaker structural representation of the present utility model can not close a floodgate time;
Fig. 4 is the right TV structure schematic diagram of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for description and interpretation the utility model, and be not used in restriction the utility model.
As shown in Figures 1 to 4, a kind of interlocking device of permanent magnetic vacuum breaker, this mechanism is mainly by chassis vehicle interlock plate 1, interlocking bent plate 2, connecting plate 3, interlock sincere sub 4, drive rod 5, divide-shut brake bearing pin 6; Chassis vehicle interlock plate 3 one end are connected with the rotating shaft on chassis vehicle, and the other end is connected with interlocking bent plate 2; Interlock sincere sub 4 by pin mounting plate, can rotate around pin; Connecting plate 3 all adopts rotatable pin to be connected with interlocking bent plate 2 with interlocking sincere sub 4; When circuit breaker is in test or service position, and circuit breaker is when closing a floodgate, and divide-shut brake bearing pin 6 and permanent magnet mechanism drive rod 5 move downward, interlocking bent plate 2 and interlocking sincere sub 4 are depressed, interlock plate 1 can not rotate, and chassis vehicle is lockable, and chassis vehicle can not shake into shaking out.When circuit breaker is in gate-dividing state, chassis vehicle is shaking in the process of shaking out, and chassis vehicle spring is upspring, interlock plate 1 rotates, interlocking bent plate 2 and sincere sub 4 jack-up of interlocking, if now closed a floodgate, divide-shut brake bearing pin 6 and permanent magnet mechanism drive rod 5 can not move downward, and are withstood, and can not close a floodgate.Thereby realize the interlock of circuit breaker operation mechanism and chassis vehicle.
Finally it should be noted that: the foregoing is only preferred embodiment of the present utility model, be not limited to the utility model, although the utility model is had been described in detail with reference to previous embodiment, for a person skilled in the art, its technical scheme that still can record aforementioned each embodiment is modified, or part technical characterictic is wherein equal to replacement.All within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
