Abstract
The utility model is related to a kind of dynamic/static contacts to plug position-limit mechanism, and including static contact and moving contact, lever is connected with the static contact inside front；The lever can be freely rotated around itself and static contact tie point；The insertion of moving contact causes lever to be 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 utility model can prevent maloperation from extracting moving contact.
Description
Technical field
The utility model is related to high-voltage circuitbreaker dynamic/static contact interconnection techniques, specifically disclose a kind of dynamic/static contact plug limiting
Mechanism.
Background technology
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.
In breaker the connection of circuit is realized with the plug cooperation of dynamic/static contact；It and 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.
Utility model content
The goal of the invention of the utility model is：For solve problem above provide it is a kind of simple in structure, it is easy for operation
Dynamic/static contact plug position-limit mechanism.
The technical solution adopted in the utility model is such：
A kind of dynamic/static contact plugs position-limit mechanism, including static contact and moving contact, is connect with the static contact inside front
It is provided with lever；The lever can be freely rotated around itself and static contact tie point；The insertion of moving contact causes lever to be 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 axis pin；The lever is socketed on axis pin, can be rotated around axis pin.
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 utility model are：
The utility model is simple in structure, ensures that the moving contact under working condition can not be from stationary contact by the ingehious design of lever
It is extracted in head, prevents maloperation from bringing security risk.
Description of the drawings
FIG. 1 is a schematic structural view of the utility model；
Fig. 2 is not plugged into bit architecture figure for the utility model；
Fig. 3 is plugged into bit architecture figure for the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and examples.
As shown in Figs. 1-3, a kind of dynamic/static contact plug 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 axis pin 12；The lever 3 is socketed on axis pin 12, can be planar free around axis pin 12 in Fig. 1 institutes
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 causes lever 3 to be forced opposite static contact 1 and be inwardly rotated up, when moving contact 2 and static contact 1
After connection in place, the rotation of lever 3 at this time is not limited by moving contact 2, and returning back to its lower end by dead weight falls within moving contact 2
It rear and is not contacted with moving contact 2.
Limited block 13 on the connecting plate 11 is set, the rotational angle of lever 3 is limited, ensures that 3 lower end of lever is firm
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 above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
