I. Overview
The CJM1 electric operating mechanism can be used for ZF-126 series gas insulated metal enclosed switchgear (GIS), and is used for the opening and closing of the three position isolation/grounding switch in GIS switchgear. A three station mechanism can achieve the opening and closing functions of isolation switches in GIS, as well as the opening and closing functions of grounding switches in GIS

2、 Principle
This institution utilizes a screw nut structure to rotate the cam plate mounted on the spindle through the forward and reverse rotation functions of the motor, driving the rotation of the spindle and achieving accurate opening and closing of isolation and grounding switches. The institution has both manual and electric operation functions.

3、 Usage environment
1. Surrounding air temperature: lower limit -25 ℃, upper limit+40 ℃.
2. The altitude shall not exceed 2000m.
3. Pollution level: Level III.
4. Shell protection level: IP54.
5. The wind pressure shall not exceed 700Pa (equivalent to a wind speed of 34m/s).
6. No fire or explosion hazards, severe pollution, no corrosive gases, and no severe vibration situations.
