monitored equipment to complete the sampling of the transformer oil. AND the
gas-oil separation part realizes the separation of the gases dissolved in oil
from the transformer oil.
4.2 Gas detection part
Gas detection part is used for the detection of the mixed gas components after
gas-oil separation.
4.3 Data collection and control part
It is used to complete the signal collection and data processing, AND to realize
the automatic control of the analysis process.
4.4 Communication part
The communication part is used to realize the communication between other
equipment and this device, AND it shall use the standard communication
interface and protocol which comply with the monitoring data and control
command transmission requirements.
4.5 Auxiliary part
The auxiliary part refers to other relevant parts which are used to ensure that
the device is working properly, such as temperature control, gas cylinders,
piping and so on.
