Description
Technical field
The utility model is related to high-voltage switch gear transmission facility technical field, and particularly a kind of 252kV sulfur hexafluoride gas is exhausted
Isolation, Grunding switch gear device in edge metal enclosed switchgear.
Background technology
With the development of high-voltage switch gear technology, the primary and secondary system architecture reliability of equipment and stability requirement are got over
Come higher.GIS miniaturizations are not exclusively simply reduced the size, and more energetically meaning is the structure that requirement reasonably simplifies element
With GIS integral arrangements, GIS is set to obtain higher operational reliability.In the development of compact apparatus, we, which also exist, much may be used
Optimization part.
The content of the invention
The purpose of this utility model is to provide that a spatial volume is small, and more compact structure is reliable and stable, is easily installed maintenance
The isolation of maintenance, Grunding switch gear device.
The utility model be achieved in that it include tank body, quiet side touch base, dynamic side conductor, gear, rack, moving contact,
Static arc contact, spring, splined shaft, insulating bar, splined shaft, moving arcing contact and interstage sleeve, it is characterized in that：Quiet side touch base and dynamic side conductor
It is arranged in tank body, moving contact and moving arcing contact are arranged on dynamic side conductor, static arc contact is arranged on quiet side touch base, constitutes three
Mutually it is total to case mechanical linkage structure.
Splined shaft drives the splined shaft in three-phase conductor to move by insulating bar, and the splined shaft in three-phase conductor drives three-phase
Gear in conductor is axially rotated, and gear moves side conductor by rack drives and does straight reciprocating motion, and three-phase isolation switch is common
With an operating mechanism.
The utility model shares a moving contact and an operating mechanism, with mechanical latching function, is avoided from structure
The possibility that disconnecting switch is also turned on earthed switch, avoids the risk of maloperation completely.Have compared with prior art
Compact overall structure, it is desirable to which mechanism operating work is small, transmission link is simple and direct reliable, effectively saves space, facilitates the factory of equipment
The work such as interior installation and debugging, transport and site installation test and repair and maintenance；Three-phase moving contact is connected by insulating bar and gear
Connect, realize mechanical linkage, more effectively ensure three-phase synchronism during breaking-closing operating；With small volume, compact conformation, it is easy to peace
Debug the high advantage of examination-transport-repair and maintenance, reliability.
Brief description of the drawings
The utility model is described further below in conjunction with accompanying drawing；
Fig. 1 is isolation, the structural representation of Grunding switch gear device.
Fig. 2 is sectional views of the Fig. 1 along A-A.
Embodiment
As shown in Figure 1-2, the isolation, Grunding switch gear device include tank body 1, quiet side touch base 2, dynamic side conductor 3, gear 4, tooth
Bar 5, moving contact 6, static arc contact 7, spring 8, splined shaft 9, insulating bar 10, splined shaft 11, moving arcing contact 12 and interstage sleeve 13, it is special
Levying is：Quiet side touch base 2 and dynamic side conductor 3 are arranged in tank body 1, and moving contact 6 and moving arcing contact 12 are arranged on dynamic side conductor 3,
Static arc contact 7 is arranged on quiet side touch base 2, constitutes three-phase combined type mechanical linkage structure, and three-phase isolation switch shares an actuating
Mechanism.During work, operating mechanism drives splined shaft 9, the splined shaft 11 in three-phase conductor is driven by insulating bar 10, so as to drive
Gear 4 in three-phase conductor is axially rotated, and is driven dynamic side conductor 3 to do straight reciprocating motion by rack 5, is completed disconnecting switch
Divide-shut brake action；During sub-switching operation, dynamic side conductor 5 and moving arcing contact 12 are moved together, when moving to certain position, move arc
Contact 12 is held tightly by static arc contact 7, stop motion, and now moves the continuation of side conductor 5 action, and spring 8 starts compressed energy-storage, is continued
Moved to separating brake direction, moving arcing contact 12 is driven by interstage sleeve 13, depart from the holding of static arc contact 7, the release energy storage of spring 8 drives
Moving arcing contact 12 is quickly moved, so as to realize that contact quick acting switching-off is operated.
