Advantages of Applying Fluorescent Fiber Optic Temperature Control Systems in Transformers

Accurate Measurement

The fluorescent fiber optic temperature control system utilizes the characteristics of fluorescent materials. When light of a specific wavelength irradiates the fluorescent material, the decay time of the emitted fluorescence has a precise corresponding relationship with temperature. โดยการวัดเวลาการสลายตัวของฟลูออเรสเซนต์, the temperature of various parts of the transformer can be accurately obtained, with an accuracy of ±1°C or higher, which is extremely critical for timely detection of potential overheating hazards in the transformer.

Anti-Electromagnetic Interference

Transformers operate in a strong electromagnetic environment, and traditional temperature measurement systems are susceptible to electromagnetic interference, นำไปสู่ข้อผิดพลาดในการวัด. The fluorescent fiber optic temperature control system uses optical signals as the transmission medium, and the optical fiber itself has good insulation and anti-electromagnetic interference capabilities, enabling it to work stably in complex electromagnetic environments and ensuring the accuracy and reliability of temperature data.

Excellent High-Voltage Insulation Performance

The quartz material used in fluorescent optical fibers has extremely high insulation performance, with a withstand voltage capacity exceeding 100kV. This allows the sensor to be directly installed on high-voltage windings, iron cores and other parts of the transformer, realizing close-range and direct temperature measurement of key parts without affecting the insulation performance of the transformer.

Long Service Life and Stability

The fluorescent materials and optical fibers in the system have good stability and durability, with a service life of 10-25 years under normal use conditions. อนึ่ง, its measurement performance is not affected by time, environment and other factors, and frequent calibration is not required, which greatly reduces maintenance costs and workload.

Market Price of Transformer Fluorescent Fiber Optic Temperature Control Systems

The price of transformer fluorescent fiber optic temperature control systems varies due to many factors, such as brand, การกำหนดค่าระบบ, number of measurement channels, and optical fiber length. Taking Fuzhou Yingnuo Electronic Technology Co., จํากัด. as an example, the price of its transformer fluorescent fiber optic temperature measurement system is 8,000 yuan per set, which includes optical fiber sensors, data acquisition equipment and supporting software. This price not only covers the cost of the equipment itself but also provides technical support and follow-up service guarantees, ensuring that customers can successfully install, debug and operate stably for a long time. It has high cost performance and is suitable for procurement by various levels of power enterprises and transformer manufacturers to improve the intelligence level of equipment.

Prices of systems from different brands and configurations may vary significantly. Some foreign high-end brands may have relatively higher prices due to high technological research and development costs and reliable product quality. While some domestic brands, while ensuring product performance, have relatively more affordable prices relying on cost advantages. When making a choice, users should comprehensively consider product performance, brand reputation and after-sales service according to their own budget and actual needs to make appropriate decisions.

Installation Process of Transformer Fluorescent Fiber Optic Temperature Control System

การเตรียมการก่อนการติดตั้ง

Determine the installation location: According to the structure and operation requirements of the transformer, determine the locations where temperature sensors need to be installed, such as winding hot spots, แกนเหล็ก, and bushing roots. มักจะ, the winding hot spot is generally located at 70%-80% of the winding height.

Prepare installation tools: Prepare necessary tools such as optical fiber laying tools, optical fiber fusion splicers, เครื่องปอกสายไฟ, screwdrivers, as well as safety equipment such as protective gloves and goggles.

ตรวจสอบความสมบูรณ์ของอุปกรณ์: Carefully check whether the fluorescent fiber optic temperature sensor, optical fiber thermometer, data transmission module and other equipment are complete and free from damage, ensuring that the equipment is in good condition before installation.

การติดตั้งเซ็นเซอร์

Optical fiber laying: Lay the optical fiber along the insulating cardboard of the transformer or other appropriate paths. Be careful to avoid excessive bending of the optical fiber (the bending radius is generally not less than 50mm) to prevent the optical fiber from being squeezed or worn by internal components of the transformer. For sensors that need to be installed inside the winding, carefully pass the optical fiber through the winding gap to ensure that the sensor is accurately installed at the predetermined position, and fix it with insulating tape or binding straps.

Sensor fixing: Firmly fix the fluorescent fiber optic temperature sensor at the measurement position. For sensors attached to the surface of the transformer, high-temperature glue or special fixtures can be used for fixing; for plug-in sensors, ensure that their insertion depth meets the requirements and 做好密封处理 to prevent oil or other impurities from entering.

Equipment Connection

Optical fiber connection: Use an optical fiber fusion splicer to splice the optical fiber of the sensor with the input optical fiber of the optical fiber thermometer to ensure good fusion quality and low connection loss. After fusion, use an Optical Time Domain Reflectometer (โอทีดีอาร์) to detect the optical fiber link to ensure there are no breakpoints and abnormal losses.

Electrical connection: Electrical connection between the optical fiber thermometer and the data transmission module, correctly connect the power cord, communication line, ฯลฯ. according to the equipment manual. Ensure that the wiring is firm to avoid poor contact due to looseness.

Communication settings: According to the requirements of the monitoring system, set the communication parameters of the data transmission module, such as baud rate, data format, โปรโตคอลการสื่อสาร (common ones include Modbus, RS-485, ฯลฯ), to ensure that the optical fiber temperature control system can communicate normally with the upper computer monitoring system.

System Debugging

Power-on inspection: After completing all equipment connections, power on the system, check the working status of the optical fiber thermometer, data transmission module and other equipment, and check whether there are abnormal indicator lights or alarm information.

การสอบเทียบอุณหภูมิ: Calibrate the fluorescent fiber optic temperature sensor using a standard thermometer, compare the temperature measured by the sensor with that measured by the standard thermometer, and if there is a deviation, perform calibration operations in accordance with the equipment manual to ensure the accuracy of the measured temperature.

Function test: Simulate the temperature change during the operation of the transformer, check whether the system can measure and display the temperature in a timely and accurate manner. When the temperature exceeds the preset alarm threshold, check whether the system can normally send out sound and light alarm signals and transmit the alarm information to the upper computer monitoring system. ในเวลาเดียวกัน, test whether the system’s functions such as data storage, การสืบค้นข้อมูลย้อนหลัง, and temperature curve drawing are normal.
