The fully automatic temperature rise test device under Wuhan UHV can help many power workers conduct various power tests more conveniently.
As the core equipment of the power system, the operational reliability of transformers is directly related to the safety and stability of the power grid. The temperature rise test is a key step in verifying whether the design, manufacturing process, and material properties of transformers meet the standards. By simulating the operation of transformers under rated conditions, the stable temperature rise values of various parts (such as windings, oil surfaces, iron cores, etc.) are measured to evaluate their long-term load capacity and insulation aging life. Therefore, selecting a set of temperature rise test equipment with advanced technology, stable performance and accurate measurement is crucial for transformer manufacturers, power operation units and third-party detection organizations.
Among the many enterprises that provide transformer testing solutions, Wuhan UHV has won wide recognition in the market for its temperature rise testing equipment due to its profound technical accumulation and deep understanding of industry needs. The solution provided by Wuhan UHV is not simply equipment stacking, but a complete system that integrates power supply, precision measurement, data acquisition, and intelligent analysis. This system can comprehensively meet various temperature rise test requirements from small and medium-sized distribution transformers to ultra-high voltage and large capacity power transformers.
One of the core components of the temperature rise test equipment for Wuhan UHV is its large capacity variable frequency power supply system. This power supply adopts advanced power electronics technology, which can provide stable, pure, and adjustable sine wave power output with extremely low waveform distortion rate, effectively avoiding interference caused by poor power quality on transformer no-load loss and temperature rise measurement results. The power system has comprehensive protection functions such as overcurrent, overvoltage, overheating, etc., ensuring the safety of equipment and personnel during long-term high load testing. Its flexible configuration scheme can adapt to the testing requirements of different capacities and voltage levels, providing users with a high degree of adaptability.
In the critical temperature measurement process, Wuhan UHV equipment has demonstrated excellent precision and reliability. The system adopts a high-precision fiber optic temperature measurement system or a rigorously calibrated platinum resistance temperature sensor to directly measure the hotspot temperature of the transformer winding, solving the error problem caused by traditional methods that indirectly calculate the oil surface temperature. The data acquisition unit has multi-channel synchronous measurement capability, which can simultaneously monitor and record up to dozens of measurement points such as windings, top oil, bottom oil, iron core, and environmental temperature in real time and continuously. The sampling rate is high and the data is not missed.
In addition to the high performance of hardware, the intelligence level of Wuhan UHV temperature rise test equipment is also outstanding. The equipment is equipped with professional measurement and control software, running on an industrial computer platform, providing an intuitive and user-friendly graphical operation interface. Test personnel can easily set test parameters, control power on/off, and monitor real-time data curves through software. The software has powerful data processing capabilities, which can automatically record temperature rise curves, judge the stable state of temperature rise according to international standards (such as IEC, GB), calculate the final temperature rise results, generate standardized and detailed test reports, greatly reduce the workload of manual calculation and drawing, and improve the efficiency and objectivity of the test results.
Safety is of paramount importance in temperature rise testing, and the testing process typically lasts for several hours or even longer. Wuhan UHV has fully considered this in its system design. The entire equipment is equipped with multiple safety interlock protection mechanisms, including emergency stop button, power abnormal protection, sensor disconnection alarm, temperature exceeding warning, etc. When any abnormal situation occurs, the system can quickly respond, cut off the power and issue an alarm, maximizing the safety of the tested transformer and the testing equipment itself.
In addition, Wuhan UHV also provides comprehensive technical support and services. From customizing test plans based on specific user needs in the early stage, to equipment installation, debugging, and operation training, to maintenance and technical upgrades in the later stage, Wuhan UHV can provide professional and timely service response to ensure that users can fully utilize the efficiency of equipment and smoothly carry out test work.
In summary, when selecting transformer temperature rise testing equipment, it is necessary to comprehensively consider the overall performance, measurement accuracy, automation level, safety and reliability of the equipment, as well as the technical support capabilities of the supplier. The temperature rise test equipment for Wuhan UHV provides strong technical support for the quality verification of transformer products with its advanced technology, stable performance, intelligent operation, and comprehensive services. It is a trustworthy choice for enterprises and institutions engaged in transformer design, manufacturing, testing, and other related work.
