The point-type optical fiber temperature measurement method is mainly applied to the online temperature monitoring and temperature alarm system under high pressure and ultra high pressure environment, and the temperature measurement range includes but is not limited to: high voltage transformer cabinet, switch cabinet, underground cable, high voltage aerial cable online Temperature detection and overheat alarm system; temperature detection and overheat alarm system for various pipe networks in power plants, overall temperature detection and overheat alarm system for large and medium transformers; ambient temperature detection and fire alarm system for substation; temperature detection and fault of generator set Diagnostic and overheating alarm systems; fire prevention and temperature alarms in coal mines and tunnels.
The optical fiber temperature transmitter can be powered by DC24V or AC220V, and the number of channels for temperature measurement can reach up to 16. It can provide standard RS485 communication interface or 4-20mA analog current output, and can transmit temperature information far to the background. Specially for the electric switchgear real-time on-line temperature detection development, the installation nimbly, the channel configuration nimbly may provide up to 4 dry contact point output according to the user's demand, may connect the skyray standard liquid crystal display instrument.
