ShanghaiCJM1 three position electric mechanism
Detailed introduction:

1、 Overview

Cjm1 type electric operating mechanism can be used in zf-126 series gas insulated metal enclosed switchgear (GIS) for breaking closing three position isolating / grounding switch in GIS switchgear. (that is, a three position mechanism can realize the opening closing functions of the disconnector in GIS the opening closing functions of the grounding switch in GIS. )

2、 Principle

The mechanism uses the screw nut structure, through the positive negative rotation function of the motor, the cam plate installed on the spindle rotates to drive the spindle to rotate, so as to realize the accurate opening closing of the isolation grounding switch. The mechanism has both manual electric operation functions.

3、 Usage environment

1. Ambient air temperature: lower limit - 25 ℃, upper limit + 40 ℃.

2. The altitude is more than 2000m.

3. Pollution level: grade III.

4. Enclosure protection grade: IP54.

5. The wind pressure shall exceed 700pa (equivalent to the wind speed of 34m / s).

6. No fire, explosion, serious pollution, corrosive gas severe vibration.
