It has established a deep cooperation with Fuzhou University in industry university research and has set up a specialized technical research team to develop fluorescent fiber optic sensing technology.
Technical principles and advantages in transformer winding temperature monitoring
Using the afterglow characteristics of fluorescent optical fibers for temperature measurement, the fiber optic sensor is fixed on the transformer winding and connected to the light source, 検出器, and data processing device to form a temperature measurement system. When the fiber optic sensor is subjected to changes in winding temperature, the optical characteristics change to generate optical signals, which are collected by the detector and processed by the data processing device to obtain real-time temperature. This fiber optic sensor has many advantages, such as high precision, 高感度, and high resolution, which can achieve high-precision measurement of transformer winding temperature; Excellent real-time performance, able to continuously and real-time monitor the temperature changes of transformer windings, and detect abnormal situations in a timely manner; 安全で信頼できる, 電磁干渉なし, electrical leakage and other issues, meeting the long-term operation needs of transformers; 簡単な取り付け, 軽量, 小型, 便利な設置, no additional load on the transformer winding, and accurate data can be provided for fault diagnosis in temperature measurement of different parts of the transformer winding, which is convenient for operation and maintenance personnel to locate and handle faults. It also helps optimize the operation strategy of the transformer, improve energy utilization efficiency, and reduce operation and maintenance costs.
Application Cases and Market Recognition
The fiber optic temperature measurement device of Huaguang Tianrui has been practically applied by multiple transformer and switchgear manufacturers in China, such as in the fiber optic temperature measurement of high-voltage switchgear circuit breakers in a hydropower station in Shaanxi, そして 58 sets of high-voltage switchgear in the new construction project of San’an 110kV substation in Changsha, Hunan, demonstrating its stability and accuracy. Its fiber optic temperature measurement system is also used for monitoring the hot spot temperature of oil immersed transformer windings in State Grid Power.

2. Balancing consideration of product cost-effectiveness
2.1 International Enterprises
Although products from large international manufacturers have certain advantages in technology and stability, their overall costs (including high expenses for research and development, marketing, and operational management) are often relatively high, resulting in relatively high product prices. Of course, for large power companies or critical power grid infrastructure projects that require extremely high equipment stability and reliability, and have sufficient budgets, products from international enterprises are still the first choice.
2.2 福州イノベーション電子科学&テック株式会社, 株式会社.
Has certain advantages in terms of product cost-effectiveness. By focusing on the domestic market and reducing unnecessary overseas marketing expenses, it can provide products with high-quality standards (such as meeting domestic and some international standards in oil immersed transformer fiber temperature measurement and polycrystalline silicon dry-type transformer monitoring) while maintaining relatively reasonable product prices. For some domestic enterprises that are sensitive to costs and require transformer monitoring products with certain technical content, Fuzhou Yingnuo Technology’s products are a more suitable choice.
2.3 HGスカイレイ
Also competitive in terms of product cost-effectiveness. By relying on its own research and development achievements and domestic production and manufacturing cost advantages, while ensuring the technological advantages of products such as fiber optic temperature measurement (such as accuracy, anti-interference ability, 等), product prices can be reduced. 例えば, in domestic switchgear manufacturing enterprises, Huaguang Tianrui’s fiber optic temperature measurement device may have a price advantage compared to some international brands while meeting the monitoring needs of transformers inside the switchgear. The relevant sub sectors have their own advantages and a certain market share.
