SL-32 spring operating mechanism

Main application

This spring mechanism can be matched with 12 or 24kV outdoor ZW32 type vacuum column circuit breaker, and can also be matched with ring cabinet vacuum circuit breaker and other vacuum circuit breakers with comparable closing power, and its performance is in line with the requirements of GB1984 "AC High Voltage Circuit Breaker", and the requirements of technical conditions of actuator in the IEC62271.100 standard.

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.

Distinctive feature
