摘要： A plurality of upstanding cooling ducts in a condenser are closed at their upper ends and only a lower header which is disposed at the lower ends of the cooling ducts communicates a tank with the cooling ducts. In another embodiment, a check valve and a gas pump are disposed in an upper conduit connecting the tank to a common upper header communicating the cooling ducts with each other at their upper ends so as to discharge the noncondensable gas from the condenser to the tank. Further, a sensing device may be disposed to sense the interface between the noncondensable gas and the vapor refrigerant in the cooling ducts, and a controller may be disposed to compare the interface level sensed by the sensing device with a reference interface level set in the controller to control the gas pump such that the actual interface level is in conformity with the reference interface level.

摘要： An evaporation-cooled gas insulated electrical apparatus comprising, in a housing, an electrical device generating heat when in operation, a condensable refrigerant convertible between liquid and vapor phases, and a noncondensable, electrically insulating gas. The condensable refrigerant and the noncondensable gas are selected so that the ratio V.sub.g /V.sub.1 of the gas phase volume V.sub.g and the liquid phase volume V.sub.1 is between 1 and 10, and so that the specific weight of the noncondensable gas is smaller than the specific weight of the vapor of the condensable refrigerant during operation, and so that the noncondensable gas and the condensable refrigerant vapor are separated due to the difference in their specific weights. The noncondensable gas is a mixture of two noncondensable gases, one of the mixed gases having a very small solubility into the condensable refrigerant compared to that of the other mixed gas, and the condensable refrigerant is a fluorocarbon liquid having a boiling point between 80.degree. C. and 160.degree. C. and a mean molecular weight of between 180 and 700.
摘要翻译：一种蒸发冷却的气体绝缘电气设备，包括在壳体中，在运行时产生热量的电气装置，在液相和气相之间可转换的可冷凝制冷剂和不可冷凝的电绝缘气体。选择可冷凝制冷剂和不可冷凝气体，使得气相体积Vg与液相体积V1的比Vg / V1为1〜10，使不凝气体的比重小于比重的可冷凝制冷剂的蒸汽，并且使得不可冷凝气体和可冷凝制冷剂蒸气由于其比重的差异而分离。不可冷凝气体是两种不可冷凝气体的混合物，其中一种混合气体与其它混合气体相比，对可冷凝制冷剂的溶解度非常小，而可冷凝制冷剂是沸点在80℃之间的氟碳液体和160℃，平均分子量在180和700之间。
