PROCEDE DE REMPLISSAGE D'UN APPAREILLAGE ELECTRIQUE A ISOLATION GAZEUSE

摘要

#CMT# #/CMT# The method involves producing fluoroketone in a gas form at predetermined pressure and temperature, and mixing the fluoroketone gas with carrier gas according to predefined proportions. A closed housing of a switchgear is filled with the fluoroketone gas and/or carrier gas in a definite manner such that partial pressure of the fluoroketone gas is maximum and equal to saturating steam pressure of the fluoroketone gas. #CMT#USE : #/CMT# Method for filling a closed housing of a switchgear for a transmission line at medium voltage i.e. volts in a range of 1000 to 52,000 volts in case of alternating current, and volts in the range of 1500 to 75000 volts in case of direct current voltage. #CMT#ADVANTAGE : #/CMT# The partial pressure of the fluoroketone gas is maximum and equal to saturating steam pressure of the fluoroketone gas, thus allowing filling of the closed housing of the switchgear in a simplified manner while avoiding surplus usage of the fluoroketone gas.
