Manufacturer of transformer fiber optic temperature measurement system

There are many manufacturers of transformer fiber optic temperature measurement systems, including IF-G4, SR-G3, SR-C, and IF-G transformer temperature controllers, fluorescent fiber optic temperature sensors, and FJINNO transformer winding hot spot temperature online monitoring system.

A significant feature of the rapid development of the national economy is the sustained and rapid growth of the power grid load. In contrast, the construction of the power grid is relatively lagging, resulting in a high load rate of power transformers. The increase in transformer load will lead to an increase in winding temperature, which in turn affects the insulation level of the transformer and ultimately shortens its lifespan. In order to solve the above problems and increase the load rate of the transformer as much as possible, it is necessary to adjust the load in real time according to the changes in the hot spot temperature of the transformer to have higher overload capacity. While avoiding transformer failures due to overload, it is also necessary to leave some space for scheduling to control the load within a safe and reliable range. In response to the traditional hot spot thermal circuit model, a mathematical model was established based on the characteristics of transformer oil temperature, taking into account factors such as environmental meteorological conditions, cooling methods, and load rates that affect transformer temperature. The winding temperature and hot spot temperature of the transformer were accurately calculated. Based on this, a power transformer hot spot temperature online monitoring and early warning system was designed to improve the safety and operational efficiency of the transformer to meet the needs of economic development.

The theory and calculation method of transformer hot spot temperature were analyzed, and the necessity of monitoring hot spot temperature research was analyzed. Fluorescent fiber optic temperature sensors were used to measure the internal temperature of transformers; Secondly, a thermal circuit model based on average oil temperature was constructed on the basis of the traditional model, and its applicability was analyzed. The effectiveness of the model was demonstrated by comparing it with the national standard calculation method and the measured temperature rise of transformers; Then, based on the hot spot temperature model established in this article, a set of online monitoring and early warning system for hot spot temperature of power transformers was designed; Finally, the online monitoring and early warning system for hot spot temperature was tested to verify its effectiveness and practicality.

As an indispensable energy source in today's world, the demand for electricity resources has steadily and rapidly increased in the process of national economic transformation and development. The development and construction of China's power grid has also entered the strategic engineering implementation stage of "West East Power Transmission, North South Power Supply Protection, and National Networking". However, China has a vast territory and uneven regional development. In some areas, the construction speed of the power grid is still relatively lagging behind, and the electricity load continues to grow rapidly, resulting in a widening gap between the actual power supply capacity of the system and the electricity demand of users. Therefore, the system often operates at high load rates, which poses an unstable threat to the operation of the power system. In order to improve the problem of high load rate, various provincial power grid companies have also proposed various improvement technologies, including increasing operating temperature, short-term dynamic capacity increase, and new heat-resistant lines.

Through the application of these technologies, the transmission capacity of the transmission line has been increased. At the same time, various equipment in the substation (circuit breakers, isolating switches, current transformers, etc.) have also undergone technical renovations, increasing the rated capacity to enable mutual coordination with the capacity of the transmission line. Although various technological renovations and overall equipment replacement have been carried out to achieve the goal of capacity expansion, there are still issues with the difficulty of substation equipment to withstand sustained high load operating conditions, leading to early retirement before the design period. This not only affects the reliability of power supply due to power outages caused by system equipment renovation, but also leads to a decrease in asset utilization efficiency.

Transformer winding temperature monitoring uses FJINNO fiber optic temperature measurement device, with 3 channels and 6 channels of multi-channel fluorescent fiber optic. The price is reasonable. Please feel free to contact our manufacturer
