Products Name：
HNPWS Series SF6 Micro-Water Density Online Monitoring System
System Overview
The
SF6 gas micro-water density online monitoring device is mainly used
to monitor micro-water density and temperature and their change trends of SF6gas in the gas filling equipment. When any index relevant to SF6 gas
changes, the change curve is given; when any relevant index reaches the alarm
status, the system alarms or automatically starts the alarm device; when any
relevant index exceeds the standard to be in danger, the system alarms or
automatically starts the locking device to ensure the safe operation of the
equipment.
It
is widely used in the field of smart grid substation and urban utility tunnel
GIL bus monitoring.
