Abstract

The invention discloses a movable type sulfur hexafluoride and carbon tetrafluoride mixed gas quick recovery device which comprises a mixed gas recovery system, a mixed gas separation system, a refrigerating unit, a sulfur hexafluoride special compressing and charging system, a carbon tetrafluoride special compressing and charging system and a vacuum-pumping system. The movable type sulfur hexafluoride and carbon tetrafluoride mixed gas quick recovery device realizes functions of the field quick recovery of a mixed insulating gas, the simple separation of a mixed gas, the storage of a separated gas, and the like. A CF4 (carbon tetrafluoride) special high-pressure compressor and an SF6 (sulfur hexafluoride) liquid filling machine which are applied in a process can greatly reduce the volumes of storage containers. Thus, the movable type sulfur hexafluoride and carbon tetrafluoride mixed gas quick recovery device solves problems that a recovery velocity of a gas is slow and the quantity of the storage containers is large when mixed insulating electrical equipment is inspected and repaired; the inspection and repair efficiency of the mixed insulating electrical equipment is improved; furthermore, the separate storage of the mixed insulating gas is also beneficial to the purification and regeneration work of the mixed insulating gas.

Description

technical field [0001] The invention belongs to the technical field of maintenance of high-voltage switchgear with mixed insulating gas in low-temperature regions, and in particular relates to a mobile rapid recovery device for mixed gas of sulfur hexafluoride and carbon tetrafluoride. Background technique [0002] Sulfur hexafluoride (SF 6 ) gas is a gas with very stable chemical properties. As an excellent insulating and arc-extinguishing medium, it is widely used in various electrical equipment. To guarantee SF 6 Normal operation of electrical equipment, SF sealed inside the equipment 6 Gas needs to maintain a certain pressure, and SF 6 The operating characteristics of gases are significantly affected by changes in ambient temperature. In northern my country and some plateau areas, extreme low temperatures below -40°C often occur in winter. Under low temperature conditions, SF 6 SF in electrical equipment 6 The gas density will gradually decrease, part of the SF 6 ...
