Introduction to the Functions of Fluorescent Fiber Optic Online Temperature Measurement System Manufacturers

Fluorescent fiber optic online temperature measurement system

1. Implement contact fluorescent fiber optic temperature measurement at 9 points on the upper and lower contacts of the incoming cabinet and the outlet cable joints, and achieve contact fluorescent fiber optic temperature measurement at 6 points on the upper and lower contacts of the busbar cabinet and the outlet cabinet;

2. Temperature measurement range -40~200C: Temperature measurement accuracy: 1C, resolution: 0.1C: Control error: 0.5C

3. The fluorescence fiber optic temperature measurement system consists of a fluorescence fiber optic temperature transmitter, a temperature measurement device, a fluorescence fiber optic sensor, a display screen, a backend host, and monitoring and early warning system software. The fluorescence fiber optic temperature sensor adopts a special ceramic packaging with strong seismic and compressive resistance. The temperature measurement fiber is immune to electromagnetic interference, and has high voltage insulation, flame resistance, and explosion-proof properties.

4. The temperature measurement device has a local display screen, installed on the instrument panel of the switchgear, using a touch measurement method, and the optical fiber adopts a fluorescent optical fiber temperature sensor provided by FJINNO manufacturer; The bending radius of the optical fiber shall not exceed 25mm; The probe diameter shall not exceed 2.5mm.

5. Optional functions include 4-20mA analog output, relay output, RS-485 communication, 61850 communication interface, which can communicate with other monitoring systems;

6. The installation is simple, feasible, and cannot damage the original switchgear structure (such as drilling holes on the busbar, disassembling switchgear components, etc.), and cannot affect the performance of the original switchgear (such as dynamic thermal stability, temperature rise performance, insulation safety distance, insulation climbing distance, etc.). There is no problem of angle alignment when installing inside the cabinet. There are multiple simple and reliable installation methods for measuring temperature in different parts of switchgear with different structures.

7. All fiber optic installations comply with electrical installation specifications, and the fiber optic has sufficient insulation strength. After installing fiber optic components, the insulation level of the switchgear meets the regulatory requirements.

8. Monitoring data can be uploaded to other systems through the network to achieve remote monitoring function.

9. The warning software can display the temperature status of each switchgear contact in real time.

10. The warning software can provide an alarm for temperature exceeding the limit and provide a specific location.

11. Early warning software can save real-time temperature data, form historical records and temperature measurement curves for querying, and also generate fault reports.

12. Alarm function

On site alarm: The device on site alarms for abnormal temperature rise of the equipment or abnormal operation of the device itself.

Remote alarm: It can be triggered remotely through the monitoring system.

Alarm temperature limit: The alarm temperature limit can be flexibly configured in the software system.
