Abstract
PURPOSE:To improve an efficiency of a cooling condensor by a method wherein a ratio between a thermal insulation gas and coolant under a low temperature and a high temperature is automatically vaired to a required value. CONSTITUTION:Mixture gas 10 having a relatively high volume of component insulative gas is discharged from the partition valve 19 during an initial starting time of operation of the electric equipment 9 and compressed, then the insulation gas is cooled by the cooling condensor 40, and the coolant is liquefied. Continuous operation of these cooling cycles causes the component of the insulation gas in the mixture gas 10 contained in the main body tank 1 to be gradually decreased as its temperature is raised, resulting in that the coolant component is replaced and increased in response to a volume corresponding to the desired volume of the insulation gas. And after the electric equipment 9 is terminated to perform its operation, and then the gas is cooled, the pressure in the main body tank 1 is decreased due to a condensation of the coolant 5, so that after the partition valve 19 is closed, the partition valve 21 is opened so as to feed the insulation gas, and the pressure in the main body tank 1 may be kept to a practical minimum valve.
