What are the functions of the fiber optic fluorescence temperature measurement system software

Temperature measurement requirements for switchgear ring main unit

As important electrical equipment in power plants and substations, switchgear and ring main unit (RMU) have elbow joints, dynamic and static contacts, and busbar joints that are in high voltage and high current working conditions for a long time. Due to factors such as surface oxidation, corrosion, loose fastening bolts, and contact aging, the contact resistance increases at the junction of dynamic and static contacts, as well as at the connection of the busbar. This causes an increase in temperature at the contact or joint, and the degree of overheating will continue to intensify, which will affect the insulation performance and equipment life.

Introduction to the Characteristics of Fluorescent Fiber Temperature Measurement System

The fluorescent fiber optic temperature probe converts the temperature information of the monitoring area into optical signals and transmits them to the fiber optic temperature transmitter. The probe of the fiber optic sensor can be directly installed on the measured point, with accurate temperature measurement and rapid response; The tail fiber is made of soft and sturdy specially made optical fibers, which have the advantages of anti electromagnetic interference, anti bending, and high impact strength; The fiber optic sheath is made of polytetrafluoroethylene, which has characteristics such as high temperature resistance, aging resistance, corrosion resistance, high insulation, and non adhesion. It can adapt to harsh usage environments such as high voltage, high temperature, and strong electromagnetic.

The fluorescence fiber optic temperature measurement system can achieve online monitoring of hot spot temperature. The entire fiber optic is made of non-metallic materials, which can withstand high voltages above 100KV and is immune to electromagnetic interference. It is an inevitable requirement for intelligent substations.

Fluorescent fiber optic temperature measurement system function

1. The on-site temperature measurement device collects real-time temperature information of the switchgear contacts and cables. The use of Inno fluorescent fiber optic temperature sensors has extremely strong electromagnetic immunity, voltage resistance, and insulation performance. Sensitive temperature sensing, stable and reliable long-term operation. The temperature measurement accuracy can reach ± 1 ℃.

2. The system comes with sound and light alarms, dry contact output, and human-machine interface display of alarm information.

3. The backend monitoring software system displays real-time temperature information of each contact point in the current switchgear, real-time curves, and historical data storing temperature information of each contact point in the past month. Using various diagnostic methods to analyze the health status of equipment, including analysis of all equipment parameter out of limit alarms and other judgment methods, to timely monitor the operation status of high-voltage switchgear.

The fiber optic temperature measurement system can automatically and manually generate various periodic reports, which can be exported and printed. The exported reports can be edited and viewed through Excel software. At the same time, the system has real-time and historical temperature curve display functions, which can accurately reflect the real-time change monitoring curve and the temperature change curve of the monitored object at a certain point in a certain period of time.
