Service device and method for using a multi-component insulating gas during maintenance of electrical switchgear systems

A service device for a multi-component insulating gas for use during maintenance of electrical switchgear systems with a system space, comprising

• a compressor with a downstream condenser,
• a storage container,
• wherein the service device is connected to the system space, and
• wherein the compressor compresses the insulating gas during removal thereof from the system space,
• wherein all components of the insulating gas remain in the compressor in a gaseous state, and
• a controller being configured to control the condenser such that a condensation of the insulating gas occurs first in the storage container, and
• a storage heating device is provided for the storage container, and
• the storage heating device is configured to heat the insulating gas to a temperature above the critical temperature of all components of the insulating gas during filling of the system space,
• a pipeline extending between the storage container and the system space;
• 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.
