sf6 Gas Mixture Maintenance Unit separating unit

Is it possible to separate SF6 by means of a SF 6 maintenance device? No it isnt possible. For this purpose special SF 6 /N 2 separating units are necessary. After the separating process the gas complies with the quality criteria for reuse stipulated in the IEC 60480 directive.

Feb 10, 2021The sf6 gas comprises both fixed and movable contacts enclosed in a gas system at a pressure of around 2.8 kg/cm 2. Whenever a fault arises, the movable contacts separate, and an arc strikes in between them.

For example, pure SF6 gas is used in gas insulated switchgears (GIS), gas insulated lines (GIL), and gas circuit breakers (GCB). One of practical solutions of controlling the emission rates of SF6 is to reuse by separation and recovery of SF6 of low concentration from the gases mixtures with nitrogen or air in the electric power industry.Author: S.E.

The method is characterized by firstly removing harmful decomposition products from the gas mixture of gas mixture sulfur, carbon tetrafluoride and nitrogen gas by a filter, secondly separating the nitrogen gas from sulfur hexafluoride and carbon tetrafluoride by a membrane separation unit, and thirdly controlling the temperature to be 100-180

Filling the gas compartments with SF6 The purified gas is returned into the gas compartment with overpressure or by means of a compressor to the desired operating pressure. The SF 6 stored in liquid form is converted into gaseous form via the evaporator installed in the maintenance device.

Sep 03, 2018The combination of the SF 6 gas and free electrons results in big, heavy ions with low rates of mobility, which effectively prevents electron avalanches and flashovers. While under the influence of electrical discharges SF 6 partially decomposes, separating into its atomic components.

Used SF6 gas containing an unacceptably high percentage of nitrogen and air can be prepared by DILO Separating plants to the desired quality. It can then be reused in gas compartments and consequently, costs for storage, disposal, transportation and the expense for new gas can be minimised. The purity degree of the prepared SF6 gas corresponds to the following standards: IEC 60480 – guideline for used SF6 gas
