Abstract
A service device for a multi-component insulating gas for use during maintenance of electrical switchgear systems comprising a compressor with a downstream condenser, a storage container, the service device is connected to a system space, and the compressor compresses the insulating gas during removal from the system space, all components of the insulating gas remain in the compressor in a gaseous state, the condenser is controlled by a controller so a condensation of the insulating gas occurs first in the storage container, a storage heating device is provided for the storage container, during filling of the system space the storage heating device heats the insulating gas to a temperature above the critical temperature of the insulating gas, wherein, a line heating device is provided which at least partially heats the pipeline between the storage container and the system space and/or heats elements in the pipeline.
