Abstract
The outdoor AC high-voltage disconnecting switch with self-locking that the present invention relates to a kind of, including the quiescent contacting knife and movable touch knife that are separately fixed on insulator, movable touch knife one end are hingedly fixed on insulator, and the other end is provided with the connected structure of identical quiescent contacting knife, it is characterised in that：The movable touch knife other end is also hinged with self-locking flipping block, self-locking flipping block lower end is connected to latch nook, the side of latch nook and quiescent contacting knife cooperates from lock nose, the side of latch nook is provided with tension spring, the state for making latch nook and keeping being in contact from lock nose, by the above-mentioned means, the present invention solves the technical problems such as open circuit caused by contact knife poor contact in the prior art and human error operate.
Description
Technical field
The present invention relates to high voltage electrical apparatus technical field, especially a kind of outdoor AC high-voltage disconnecting switch with self-locking.
Background technology
Electric system of the outdoor AC high-voltage disconnecting switch for the three-phase alternating current rated frequency 50Hz of rated voltage 10kV,
In zero load progress disjunction, close and the equipment such as the high voltage bus to being overhauled, breaker and live high voltage circuit into
Row electrical isolation is used, and in the prior art, outdoor AC high-voltage disconnecting switch relies solely on two panels copper bar deformation production when closing a floodgate
Raw clamping force makes quiescent contacting knife be combined together with movable touch knife, after long-time use, be easy to cause disconnecting link poor contact, causes line
Road failure, in addition the contact knife of this type be easy in the case that by external force, there is a situation where contact knife open circuits, cause unnecessary
Have a power failure.
Invention content
In view of the foregoing drawbacks, the invention mainly solves the technical problem of providing a kind of outdoor AC high-voltage with self-locking every
Pass is left, contact knife poor contact in the prior art is can effectively solve the problem that, is easy the technical problems such as open circuit.
In order to solve the above technical problems, one aspect of the present invention is：A kind of outdoor friendship with self-locking is provided
High voltage isolator is flowed, including the quiescent contacting knife and movable touch knife being separately fixed on insulator, movable touch knife one end is hingedly fixed in absolutely
On edge, the other end is provided with the connected structure of identical quiescent contacting knife, it is characterised in that：The movable touch knife other end is also hinged with certainly
Flipping block is locked, self-locking flipping block lower end is connected to latch nook, and the side of latch nook and quiescent contacting knife cooperates from lock nose, latch nook
Side be provided with tension spring, so that latch nook is kept the state that is in contact with from lock nose.
In solution technique, the top of self-locking flipping block, which is provided with, wins ring.
In solution technique, stopper is provided on movable touch knife, stopper is located at the side of latch nook movement.
The beneficial effects of the invention are as follows：Outdoor AC high-voltage disconnecting switch of this spline structure with self-locking have prevent operator
Member's accidentally touches caused breaking phenomena.
Description of the drawings
Fig. 1 is the structural schematic diagram of the embodiment of the present invention.
Fig. 2 is the partial enlargement structural representation of the embodiment of the present invention.
Fig. 3 is the embodiment of the present invention from lock nose structural schematic diagram.
The label of each component is as follows in attached drawing：1, movable touch knife 2, quiescent contacting knife 3, insulator 4, electric conductor 5, self-locking overturning
Block 6, latch nook 7, from lock nose 8, tension spring 9, win ring 10, stopper.
Specific implementation mode
Below in conjunction with the accompanying drawings to embodiment further instruction.
As shown in Figure 1, Figure 2, Figure 3 shows, in embodiment, the outdoor AC high-voltage disconnecting switch with self-locking, including be mutually linked
In conjunction with movable touch knife 1, quiescent contacting knife 2, the electric conductor 4 on the movable touch knife 1 and 3 top of insulator is hinged, and quiescent contacting knife 2 is located at other one
On the electric conductor 4 on 3 top of a insulator, 4 one end of the movable touch knife is provided with two panels copper bar, two panels copper bar there are with quiescent contacting knife 2
Matched gap, quiescent contacting knife 2 are the cuboid of protrusion, and self-locking flipping block 5 is arranged with 2 abutting end of static electric shock in the movable touch knife 1,
Self-locking flipping block 5 is hinged with movable touch knife 1, and 5 lower end of self-locking flipping block is connected to latch nook 6, latch nook 6 on quiescent contacting knife 2
It cooperates from lock nose 7, in order to keep 6 self-locking state of latch nook, 5 side of self-locking flipping block is distributed with tension spring 8, and the one of tension spring 8
End is fixed on self-locking flipping block 5, and the other end is fixed on movable touch knife 1, under the pulling force effect of spring 8,5 band of self-locking flipping block
Dynamic latch nook 6 is caught on to side rotation under lock nose 7, such state, and movable touch knife 1 is locked together with quiescent contacting knife 2, when needing to detach
When movable touch knife 1 and quiescent contacting knife 2, can pull self-locking flipping block 5 makes latch nook self-locking when in disengagement nose, at this time movable touch knife 1 just can with it is quiet
Contact knife 2 detaches.
In embodiment, personnel pull self-locking flipping block 5 and open latch nook 6, the top of self-locking flipping block 5 in order to facilitate the operation
It is provided with and wins ring 9, self-locking flipping block 5 can be pulled by winning ring 9 by force, can also drive movable touch knife 1 and quiescent contacting knife 2
Separation.
It in a further embodiment, can be in self-locking flipping block 5 in order to limit the flip angle range of self-locking flipping block 5
One or more stoppers 10 are set on flip-flop movement track, stopper 10 is located on movable touch knife 1, in embodiment, stopper 10
In the angle formed between latch nook 6 and self-locking flipping block 5, a stopper 10 can limit self-locking flipping block 5 simultaneously
Counterclockwise and clockwise overturning stroke.
In embodiment, porcelain piece insulator, rubber insulator or composite insulator can be selected in the insulator 3.
The above description is merely a specific embodiment, but scope of protection of the present invention is not limited thereto, any
The change or replacement expected without creative work, should be covered by the protection scope of the present invention.
