| 摘要 |
The invention relates to a service device for a multi-component insulating gas, in particular for use during maintenance of electrical switchgears with a system space, comprising – a compressor (3) with a downstream condenser (32), – a storage container (6), – wherein the service device is or can be connected to a system space (1), and – the compressor (3) compresses the insulating gas during the removal thereof from the system space (1), wherein all components of the insulating gas remain in the compressor (3) in a gaseous state, and the condenser (32) is controlled by a controller (8) such that a condensation of the insulating gas preferably occurs first in the storage container (6), and a storage heating device (61) is provided for the storage container (6), and during filling of the system space (1) the storage heating device (61) heats the insulating gas to a temperature above the critical temperature of all components of the insulating gas, wherein, in particular, a line heating device (90) is provided which at least partially heats the pipeline between the storage container (6) and the system space (1) and/or heats elements in the pipeline, such as, for example, filter housings or similar. |
