In the power industry, test transformers are essential equipment for power equipment testing and preventive tests. With the development of China’s power industry, the voltage levels required for test transformers have become increasingly higher. However, traditional oil-immersed test transformers, in terms of volume, weight, and performance, are increasingly unable to meet the requirements of on-site work.
With the advancement of basic scientific research in our country and the application of new materials and new technologies, the new medium, sulfur hexafluoride gas, has been introduced into the application field of power equipment. Due to its excellent insulation and arc-extinguishing properties, as well as its non-flammability, it has been widely used as a new insulating medium, which has led to the emergence of gas-filled test transformers.
After years of efforts, an inflatable lightweight test transformer has been successfully developed. Compared with the traditional oil-immersed lightweight test transformers, this series of products weighs 20% to 60% less (depending on the voltage and capacity level), and is free from oil pollution. The voltage level of a single test transformer can reach 300KV. Due to the adoption of a new production process, the technical performance of the products has been significantly improved, and it is particularly suitable for use in fieldwork and situations requiring frequent movement.
The parameters of the inflatable test transformer are as follows:
> Voltage level: 10 – 600 KV
> Capacity range: 1 – 600 KVA
> No-load current: < 7%
> Impedance voltage: < 8%
Rated voltage-induced partial discharge: < 5PC
