Electrical apparatus for the generation, transmission, distribution and/or usage of electrical energy and method for recovering a substance from an insulation medium of such an apparatus

摘要

An electrical apparatus (10) for electrical energy handling comprises a housing (12) with at least one insulation space (16), in which an electrical component (14) is arranged and which contains an insulation medium (22) surrounding the electrical component (14). The insulation medium (22) comprises an organofluorine compound and at least one further gaseous component. Apparatus (10) further comprises a gas flow generating device (24) for flowing an initial gas mixture, containing the organofluorine compound and at least one further component of the insulation medium, out of the insulation space (16) through an outlet opening (26) arranged in the housing (12). A substance recovery device (30) downstream of outlet opening (26) comprises a separator (34) for separating the organofluorine compound from the at least one further component of the initial gas mixture, the separator (34) being a liquefaction device (36) for liquefying and/or solidification device for solidifying the organofluorine compound.
