SL-1E spring-operated mechanism
Main application
This spring mechanism is mainly used in the rated voltage 12kV environmental protection gas ring network cabinet vacuum circuit breaker cabinet or switchgear matched with it. It meets the requirements of GB1984 "AC High Voltage Circuit Breaker" and IEC62271.100 standard on the technical conditions of the actuator mechanism.
Working conditions
A. The upper limit of ambient air temperature is +70℃ and the lower limit is -40℃;
B.The altitude is not more than 2000m above sea level;
C. Relative humidity daily average not greater than 95%, monthly average not greater than 90%;
Saturated water vapor pressure daily average is not greater than 2.2X10-3Mpa, monthly average is not greater than 1.8X10-3 Mpa;
D. No fire, explosion, serious filth, corrosion and violent vibration of the place;
E. Special use of the environment should be consulted in advance to determine.
