Abstract

The invention provides a sulfur hexafluoride automatic recycling device. The sulfur hexafluoride automatic recycling device is characterized by comprising a gas storage device, a filter system, a compression system, a pipeline system and an electric control system which are mounted on a supporting device; the filter system comprises a granule filter and a water filter; the compression system comprises a compressor and a recovery pump; the pipeline system comprises pipelines connecting the devices and control valves on the pipelines; and the electric control system comprises a sensor, an electric control member and an instrument display device. By adopting a lubricating oil-free and leakage-free non-metal spacer sleeve magnetic coupled power transmission compressor, the recovered gas does not contain oil, and regeneration of gas is quite simple and feasible, and the device is leakage-free and the influence on the environment is reduced to the lowest extent. Meanwhile, the sulfur hexafluoride automatic recycling device is simple and feasible to maintain, low in cost and faster to maintain.

Description

technical field [0001] The invention relates to the technical fields of SF6 application such as electric power, metallurgy and aerospace, and in particular to an automatic recovery and treatment device for sulfur hexafluoride. Background technique [0002] Sulfur hexafluoride gas is an excellent insulating and arc extinguishing gas, which is widely used in various electrical equipment. In order to ensure the normal operation of the equipment, the oil SF6 gas is usually sealed in the equipment and maintained at a certain pressure. SF6 gas itself is non-toxic, but its decomposition products are extremely harmful to the environment, mainly because its decomposition products contain acidic substances, especially HF and SO2, which are toxic and corrosive, which not only affect the service life of equipment, but also It will pollute the environment, endanger the safety of personnel and cause a waste of resources. When the equipment is working, there will be gas loss due to leaka...
