Switch cabinet having compressed-gas-filled chambers

摘要

In the case of a switch cabinet of a high-voltage switching installation, at least two chambers (1, 4, 5) are provided which are hermetically sealed from the external atmosphere, are filled with compressed gas and are separated from one another, and between which a defined connecting channel (18, 9) is provided, and at least one of which is closed by a removable cover (7). In order in this case to prevent any bypass flow of insulating gas from the chambers (1) and (4) when necessary, a controllable valve (8) is inserted into the connecting channel (9, 18), which valve (8) can be switched, in particular, manually. <IMAGE>
