AI Technical Summary
The existing SF6 gas-filled switchgear disconnector, after a significant increase in the isolation distance, requires excessive operating force and is prone to jamming, making it difficult to achieve smooth closing or opening operations.
The position of the isolating moving contact is controlled by a pull rod push-pull mechanism. The pull rod rack meshes with the rotating shaft gear, driving the drive shaft to rotate and realize the insertion of the isolating moving contact in the isolating sleeve, ensuring stable and smooth operation.
This achieves appropriate closing or opening force for the disconnecting switch, avoids jamming, makes operation more intuitive, and improves the stability and reliability of the transmission mechanism.

Abstract
Claims
1. An isolation transmission mechanism for an environmentally friendly gas cabinet, comprising a housing, characterized in that: A sealing shaft is rotatably connected to the bottom of the housing. A telescopic mechanism for isolating the moving contact is connected to the sealing shaft. One end of the telescopic mechanism is connected to the isolating moving contact. An isolation sleeve is connected to the inner wall of the housing through a sleeve. The telescopic mechanism is used to extend the isolating moving contact into the isolation sleeve. A shaft gear is connected to the lower end of the sealing shaft. A pull rod rack is meshed on the side of the shaft gear. A pull rod is connected to one end of the pull rod rack. One end of the pull rod is located below the housing, and the other end is located outside the housing. The other end of the pull rod is used to connect to the operating mechanism.
2. The isolation transmission mechanism of the environmentally friendly gas cabinet according to claim 1, characterized in that: The direction of movement of the pull rod is consistent with the length direction of the box.
3. The isolation drive mechanism for an environmental gas cabinet of claim 1, wherein: The telescopic mechanism includes a first drive shaft and a second drive shaft distributed vertically. The second drive shaft is connected to a sealed rotating shaft. The first drive shaft and the second drive shaft are connected by a spline and rotate synchronously. A gear is connected to the upper end of the first drive shaft, and a gear is also connected to the upper end of the second drive shaft. An isolation moving contact is inserted into the isolation sleeve. An internal rack of the moving contact is formed on the surface of the isolation moving contact, and the internal rack of the moving contact meshes with the gear.
4. The isolation drive mechanism for an environmental gas cabinet of claim 3, wherein: The isolation sleeve includes an insertion connection part and a contraction part. The contraction part extends into the sleeve, and the diameter of the contraction part is smaller than the diameter of the insertion connection part.
5. The isolation drive mechanism for an environmental gas cabinet of claim 4, wherein: The plug-in connection, the retractable part, and the isolating moving contact are all concentrically distributed.
