Encapsulated electrical device has gas monitor connected to flushing gas outlet that triggers alarm signal if hazardous components detected, throughflow monitor in flushing gas outlet

摘要

The device has a housing (6) for the device (1) through which a flushing gas (8) is passed at above atmospheric pressure using a flushing gas inlet and outlet, a gas monitor (13) connected to the outlet that triggers an alarm signal if hazardous components are detected in the gas and a throughflow monitor (15) in the outlet that produces a second alarm signal if the flushing gas throughput falls below a threshold value.
