Abstract
The present invention relates to a kind of dynamic/static contacts to plug position-limit mechanism, including static contact and moving contact, is connected with lever with the static contact inside front；The lever can be freely rotated around it with static contact tie point；The insertion of moving contact is so that lever is forced to rotate, and after moving contact is connect in place with static contact, lever returns back to its lower end and falls within moving contact rear.The present invention can prevent maloperation from extracting moving contact.
Description
Technical field
The present invention relates to high-voltage circuitbreaker dynamic/static contact interconnection techniques, specifically disclose a kind of dynamic/static contact plug position restrainer
Structure.
Background technique
High voltage isolator is device for switching important in power plant and substation's electrical system, need to be matched with high-voltage circuitbreaker
Set uses.
The connection of circuit is realized in breaker with the plug cooperation of dynamic/static contact；And it in practical applications can be because of behaviour
Workmanship's maloperation, moving contact is extracted, i.e. power-off suddenly, can generate arclight, there are security risks.
Summary of the invention
It is an object of the invention to: a kind of structure is simple to solve the above problem, sound touching easy for operation
Head plug position-limit mechanism.
The technical solution adopted by the present invention is that such:
A kind of dynamic/static contact plug position-limit mechanism, including static contact and moving contact, connect with the static contact inside front
It is provided with lever；The lever can be freely rotated around it with static contact tie point；The insertion of moving contact so that lever is forced to rotate,
After moving contact is connect in place with static contact, lever returns back to its lower end and falls within moving contact rear.
Further, connecting plate is extended downward in the static contact inside front；It connect and sets with the connecting plate
It is equipped with pin shaft；The lever is socketed on pin shaft, can be rotated around pin shaft.
Further, limited block is set in the connecting plate, for limiting the rotational angle of lever.
In conclusion due to the adoption of the above technical scheme, the beneficial effects of the present invention are:
The configuration of the present invention is simple guarantees that the moving contact under working condition can not be out of static contact by the ingehious design of lever
It extracts, prevents maloperation from bringing security risk.
Detailed description of the invention
Fig. 1 is schematic structural view of the invention；
Fig. 2 is that the present invention is not plugged into bit architecture figure；
Fig. 3 is that the present invention is plugged into bit architecture figure.
Specific embodiment
Invention is further described in detail with reference to the accompanying drawings and examples.
As shown in Figure 1-3, a kind of dynamic/static contact plugs position-limit mechanism, including static contact 1 and moving contact 2, with the stationary contact
First 1 inside front is connected with lever 3；Specifically, the static contact 1 extends downward with connecting plate 11；With the company
Fishplate bar 11 is connected with pin shaft 12；The lever 3 is socketed on pin shaft 12, can be planar free around pin shaft 12 in Fig. 1 institute
Rotation.
One end of the lever 3 is connect with static contact 1, and the other end is free end；
The insertion of moving contact 2 is so that lever 3 is forced opposite static contact 1 and is inwardly rotated up, when moving contact 2 and static contact 1
After connection in place, the rotation of lever 3 is not limited by moving contact 2 at this time, is returned back to its lower end by self weight and is fallen within moving contact 2
It rear and is not contacted with moving contact 2.
Limited block 13 is set on the connecting plate 11, the rotational angle of lever 3 is limited, guarantees that 3 lower end of lever is rigid
2 rear of moving contact is fallen within well, and the gap between lower end and moving contact 2 can not as low as move moving contact 2 substantially.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
