Thefully automatic temperature rise test deviceunder Wuhan UHV can help many power workers conduct various power tests more conveniently.
In the field of power transformer manufacturing, maintenance, and scientific research identification, temperature rise testing is a key project to verify the rationality of transformer design, process level, and long-term operational reliability. This experiment simulates the operation of a transformer under rated conditions and measures the stable temperature rise of key parts such as windings, iron cores, and top oil layers. The results directly affect the load capacity, insulation aging rate, and service life of the transformer. The complexity of the technical scheme and the comprehensiveness of the configuration of the transformertemperature rise test equipmentrelied upon for this experiment determine its value positioning in the market. As an important equipment supplier in this field, Wuhan UHV provides solutions covering the entire process from power excitation to data acquisition, and the value system of the equipment is constructed by multiple factors.
The transformertemperature rise test equipmentis not a single instrument, but an integrated system engineering. Its core value is first reflected in the capacity and quality of the experimental power supply. The test power supply needs to be able to provide the huge active and reactive power required under the rated working conditions of the transformer stably and for a long time. The power supply scheme provided by Wuhan UHV may involve large capacity variable frequency power supply system, synchronous generator set or special power compensation combination. Its technical core lies in how to efficiently, economically and reliably solve the power supply problem of large capacity transformers. Especially for ultra-high voltage and ultra-large capacity transformers, the progressiveness and stability of the power supply scheme are the primary part of the equipment value.
A high-precision and highly reliable measurement system is another core value of temperature rise testing equipment. The temperature rise test of transformers has a long duration, multiple measurement parameters, and requires accuracy, including winding resistance (usually indirectly calculated by direct current resistance method), oil temperature, ambient temperature, cooling medium flow rate, input voltage, current, power, etc. The measurement system of Wuhan UHV will integrate high-precision data acquisition devices, multi-channel temperature inspection instruments, standard transformers, and professional resistance measurement units. The system not only needs to ensure measurement accuracy in strong electromagnetic interference environments, but also needs to have long-term stability and automated data recording and processing capabilities. The technical content of this software and hardware configuration directly determines the credibility of the experimental data.
The automation level and humanized design of the experimental system are important manifestations of the value of modern temperature rise testing equipment. An advanced Wuhan UHV temperature rise test system is usually equipped with a computer centralized control platform. This platform can achieve automatic lifting and lowering of the test power supply, smooth adjustment of the load, real-time collection and monitoring of data from various measuring points, automatic drawing of temperature rise curves, and result judgment and report generation according to preset standards. This highly automated design greatly reduces the labor intensity of operators, reduces human errors, and improves experimental efficiency and safety. These intelligent and integrated functions endow the equipment with higher added value.
The safety protection design and structural technology of the equipment are also an indispensable part of its value. The temperature rise test involves high voltage, high current, and a long test cycle, which is crucial for the safety protection of the equipment itself and the tested transformer. Wuhan's ultra-high voltage equipment will be equipped with multiple overcurrent, overvoltage, and undervoltage protections in the electrical circuit, complete grounding and isolation measures, and emergency shutdown systems. Structurally, the equipment layout is reasonable, the wiring is convenient, the labeling is clear, and high-quality components and materials are used to ensure excellent performance and reliability even under harsh conditions of long-term and continuous operation. This investment in safety and durability is the fundamental guarantee for the long-term stable operation of the equipment.
Lastly, but most importantly, the value of technical support and services. The temperature rise test technology for transformers is complex and the system integration is high. The value provided by Wuhan UHV goes far beyond the equipment hardware itself, including preliminary test plan demonstration, mid-term on-site installation and commissioning, personnel training, as well as later maintenance and technical support. The ability to provide quick response and professional problem-solving services, helping users successfully complete every important experiment, is a key component of the overall value of the equipment. For users, its significance is equally important as the physical device.
In summary, evaluating the comprehensive value of transformertemperature rise testing equipmentrequires a comprehensive and in-depth technical and economic analysis. It is determined by multiple dimensions including test power supply capability, measurement system accuracy, automation control level, safety process standards, and full cycle technical services. When inspecting Wuhan UHV and other related equipment, users should focus on their own transformer's parameter range, compliance with test standards, demand for test efficiency, and total cost of long-term use, so as to select solutions with advanced technology, reliable performance, and perfect service, and ensure that this key test can provide accurate and authoritative data support for the safe operation of transformers.
