GN19 isolates the three -phase power system for AC 50Hz and voltage 12kV, which is used for division and co -circuit without load without load.
Environmental conditions
1. Surrounding air temperature: upper limit+40 ° C, lower limit -30 ° C.
2. Altitude: ≤1000m.
3. Relative humidity: The average daily average is not greater than 95%, and the average monthly average is not more than 90%.
4. No frequent vibration.
5. There is no place for fire, explosion hazard and chemical corrosion.
The main structure
The conductive section is mainly composed of a tactile knife and a static contact. The static head is installed on the pillar insulator at both ends. Each phase of the tactile knife is composed of two slot -type pictures. Moreover, the mechanical strength of the touch knife is improved, and the dynamic stability of the switch is improved. One end of the touch knife is installed on the static tentacles through the axis sales (bolt). Touch knife contact pressure is maintained by contacting spring at both ends. Equipment assembly: It consists of the spindle and limit board of the chain. The limit board is mainly used to ensure that the conductive knife "divide" and "combined" is obtained.
