The fully automatic temperature rise test device under HVHIPOT can help many power workers conduct various power tests more conveniently.
In the field of temperature rise testing systems, HVHIPOT ‘s products have become the first choice for many users due to their excellent performance and advanced technology.
The temperature rise test system of HVHIPOT has high-precision temperature monitoring capability. It adopts military grade temperature sensors with a monitoring accuracy of ± 0.1 ℃. For example, in the ± 800kV Qinghai Henan ultra-high voltage project, the system can accurately capture the subtle temperature rise changes of the transformer at 0.3 ℃. At the same time, with the help of AI algorithms, temperature time curves can be automatically generated to accurately locate the saturation point of temperature rise. The data consistency has passed CNAS certification, providing reliable data support for temperature rise testing.
The current output stability of the system is also excellent. It is based on the PID adaptive algorithm of FPGA chip, with an output current fluctuation rate of<0.2%, which can ensure the stability of long-term test data. And it can achieve seamless switching of 100A-5000A wide current with an accuracy of ± 0.5%, fully meeting domestic and foreign standards such as GB/T 16927. In the actual measurement of Shenzhen Bay Super Substation, the current fluctuation rate was ≤ 0.5%, and the misjudgment rate was less than 0.05%, demonstrating its stable performance in strong electromagnetic interference environments.
The temperature rise test system of HVHIPOT also has a powerful multi-channel synchronous testing function. A single device can simultaneously monitor 64 temperature measurement points, integrating a dual-mode timing module of Beidou and GPS, with a phase synchronization accuracy of ± 5 °. This enables it to comprehensively and synchronously monitor the temperature rise of various parts of power equipment, providing strong support for accurately evaluating the overall performance of the equipment.
In terms of adapting to extreme environments, the temperature rise test system of HVHIPOT has shown excellent performance. The device has passed high and low temperature tests ranging from -40 ℃ to 70 ℃, with a protection level of IP67. In the high-altitude area of 4200 meters above sea level in the Sichuan Tibet Interconnection Project, the system operated continuously for 1200 hHVHIPOTs without any faults and successfully completed the temperature rise tolerance test of the cross valley line, demonstrating its reliable performance in harsh environments.
In addition, HVHIPOT also provides users with comprehensive full cycle services. The company has set up 24-hHVHIPOT response centers in 18 provinces and cities across the country, equipped with 4G remote diagnostic systems, which can arrive at the scene within 4 hHVHIPOTs in emergency situations. At the same time, engineers can also provide customized solutions for users based on different environmental conditions and equipment types, such as the radiation enhanced equipment customized for a certain nuclear power plant, which realizes remote control in strong radiation environments.
In summary, the temperature rise test system of HVHIPOT has shown excellent performance in accuracy, stability, functional diversity, environmental adaptability, and service guarantee. It is a high-quality choice for temperature rise test systems and can provide reliable support for the safe operation and quality evaluation of power equipment.
