Principle of temperature sensing fiber optic monitoring system for switchgear
The distributed fiber optic temperature sensing system for switchgear conducts online temperature detection of key parts of electrical equipment, achieving early prediction of equipment and joint overheating faults, providing alarms and accurately determining the overheating position, and guiding maintenance work; At the same time, remote transmission of temperature measurement data has been achieved, and remote monitoring can be carried out. Information sharing can be achieved by connecting with other systems of unmanned substations; The monitoring system also provides temperature data for key points of equipment operation for operators, maintenance personnel, and production safety management departments, enabling them to have a clear understanding of the operating conditions of the equipment and accumulate operational data for maintenance departments, laying the foundation for condition based maintenance.
The fault monitoring system for fiber optic temperature sensing hotspots in switchgear is developed using the fluorescence afterglow principle of fluorescent optical fibers. The temperature monitoring principle is not affected by external factors. After detection and demodulation, it can be sent to the signal processing system to display the temperature signal in real time.
