Description
Technical field
It the utility model is related to generator optical fiber sensing structure.
Background technology
Turbine-generator units temperature is one of important indicator of turbine-generator units running situation, at present, more and more
Power station proposes higher requirement to generator-temperature detection monitoring, and temperature measurement technology is gradually surveyed from traditional element thermometric to optical fiber
Temperature is changed.Optical fiber sensing technology is accompanied by optical fiber and a kind of new sensing technology of Fibre Optical Communication Technology development,
Temperature detection is carried out directly as sensor with optical fiber.Optical fiber sensing structure at generator unit stator copper ring lead is base
In the novel temperature measurement form that optical fiber sensing technology is carried out, realize and the temperature of generator copper ring lead-out wire is monitored in real time.
The content of the invention
The purpose of this utility model is disclosed at a kind of generator unit stator copper ring lead-out wire simple in construction, dependable performance
Novel optical fiber temperature sensing arrangement.The technical solution of the utility model is：
By fibre optical sensor (1), silicon rubber self-adhesive tape (2), copper ring major insulation (3), coupler (4), external fiber (5) group
Into.Using silicon rubber self-adhesive tape (2) by fibre optical sensor (1) colligation close to main lead side copper bar on, after colligation is firm
Wrap copper ring major insulation (3), fibre optical sensor (1) carry lead through copper ring major insulation (3) extraction after, by coupler (4) with
External fiber (5) is connected, and unit optical fiber temperature measurement system terminal is led to through external fiber (5) --- fiber-optic signal adjuster (6), it is right
The temperature of stator copper ring lead-out wire carries out real time on-line monitoring.
Digital temperature sensor is mostly based on electricity transmission, larger by electromagnetic field effects, has a foregone conclusion for temperature survey
Sex-limited, fibre optic temperature sensor has communication rapid, low, clever to environmental factor requirement compared with conventional digital temperature sensor
The advantages that sensitivity is high, extensive use can be carried out in power industry, the temperature of real-time watch device, ensure that electric equipment operation is being pacified
It is region-wide, lifting system stability.
