1, Product description
Based on fiber Bragg grating (FBG) technology, real-time monitoring of multiple physical quantities can be realized in electric power industry:
● Real-time temperature monitoring: high voltage distribution room contacts and cables, high voltage cable quasi-distributed monitoring and any high voltage, temperature monitoring of complex magnetic field complex field, the temperature range is (-40~1000) ℃.
● Real-time vibration monitoring: on-line vibration frequency monitoring of large equipment, generators and motors, the frequency is 20Hz~1kHz
● Real-time monitoring of vibration displacement: power system transformer, reactor, displacement monitoring of large generators (0~500) µm
● Real-time strain monitoring: strain monitoring of wind turbine blade ±1500με
2, product characteristics
● Ensure the voltage isolation of the power part, good linearity, high precision
● Anti-pressure, anti-impact, anti-vibration, anti-electromagnetic interference, very good transmission quality
● Multi-channel transmission with long distance
● Small size, light weight, easy to be installed, the amount maintenance is small in the latter stage
3, Site application and test diagram
● It can be used for vibration monitoring of transformer, generator sets, wind turbine generator sets and deformation monitoring of wind turbine blade, etc
