PGS-24 24kV Outdoor SF6 Circuit Breaker
Description
PGS-24 24kV Outdoor SF6 Circuit Breaker
General Introduction
LW(PGS)-24 series outdoor high voltage SF6 circuit breaker is a new outdoor high-voltage electrical sulfur hexafluoride gas as extinguishing and insulating medium. There are three types of operating mechanism:I type manual energy storage spring operating mechanism, II type motor energy storage spring operating mechanism
Working Conditions
Ambient temperature: -10℃~ +40℃(conveyance under -30°C is allowed)
Relative humidity: daily average relative humidity: ≤95%; monthly average relative humidity≤90%; daily average saturated vapor pressure ≤2.2KPa; monthly average value ≤1.8KPa
Altitude: ≤2000m
Earthquake intensity: ≤8 degree
The installation should be free from fire, explosion, severe vibration, chemical corrosion and serious pollution
