GAS INSULATED ELECTRICAL APPARATUS AND METHOD FOR MONITORING THE LOAD OF AN ABSORBER IN A GAS-INSULATED ELECTRICAL APPARATUS

摘要

A gas-insulated electrical apparatus (1), in particular a switchgear, includes: a gas chamber (2) filled with an insulation gas and an absorber (10) for absorbing impurities present in the insulation gas. The absorber (10) is positioned in the gas chamber (2). The gas-insulated electrical apparatus (1) further includes a monitoring device (20) for non-invasive monitoring of a load of the absorber (10).;A method for monitoring a load of an absorber (10) for absorbing impurities present in an insulation gas of a gas-insulated electrical apparatus (1), wherein the absorber (10) is positioned in a gas chamber (2) of the gas-insulated electrical apparatus (1), the method includes: non-invasively measuring a physical property of the absorber (10) or of a compartment (3) of the gas chamber, in which the absorber (10) is positioned. The physical property allows conclusions on the load of the absorber (10).
