Manufacturers of fluorescent fiber optic temperature measurement technology applied to power electrical and microwave magnetic field temperature monitoring

Optical fiber temperature measurement technology can solve the problem of hot spot temperature measurement in power equipment. It has the characteristics of high voltage resistance, high insulation, and resistance to electromagnetic interference, and is widely used in the field of hot spot temperature measurement of electrical equipment in the power system in 2024.

The temperature measurement technology for electrical equipment mainly includes two types: fluorescent fiber optic temperature measurement technology and infrared temperature measurement technology. Among them, infrared temperature measurement technology can only measure the surface temperature of electrical equipment and cannot measure the hot spot temperature inside electrical equipment. The installation method of fluorescent fiber optic temperature measurement technology is consistent with the conventional electrical signal temperature sensor and can be directly embedded in electrical equipment, so it has strong convenience of use.

The fluorescence fiber optic temperature measurement system is divided into two parts: the bottom temperature measurement unit and the upper computer system. The bottom temperature measurement unit is composed of multiple fiber optic temperature measurement devices such as transformers, high-voltage switchgear, high-voltage busbars, and cable heads. The upper computer system is composed of the main control room, on-site monitoring devices, etc. The fiber optic temperature measurement device adopts RS485 interface communication mode, which is converted into fiber optic communication signals through photoelectric converters. It realizes remote communication with the upper computer system composed of remote control rooms, on-site monitoring devices, etc. to improve the reliability and anti-interference ability of the communication system.

The IF-G fluorescent fiber optic temperature sensor is also suitable for temperature measurement in microwaves, which is not affected by electromagnetic interference and does not affect the distribution of the microwave field. FJINNO fluorescent optical fiber can be used for direct contact measurement with samples and is widely used in microwave fields such as microwave hyperthermia, food processing, and microwave digestion.
