Audited Supplier KGYDQ Inflatable Test Transformer Breakdown Voltage Tester Dielectric Strength Testing Transformer
Product Introduction
KGYDQ inflatable test transformer is a necessary test equipment for power equipment inspection and preventive test. With the development of China's power industry, the voltage level requirements of test transformers are getting higher and higher, while the traditional oil-immersed test transformers are more and more unable to meet the requirements of field work in terms of volume, weight or performance.
With the progress of basic scientific research in China, the application of new materials and new processes has pushed the new medium sulfur hexafluoride gas to the application field of electric power equipment. Sulfur hexafluoride gas has been widely used as a new insulating medium because of its excellent insulating properties, arc extinguishing properties and non-flammability.
After years of efforts, Wuhan Kekang Power has successfully researched the KGYDQ inflatable test transformer. Compared with the traditional oil-immersed light test transformer, this series of products reduces the weight by 20%-60% (depending on the voltage and capacity level), and there is no oil pollution. The voltage level of a single inflatable AC test transformer can reach 300KV. Due to the adoption of a new production process, the technical performance of the product has been greatly improved, especially suitable for field work and frequent movement of the working conditions.

Selection of test transformer:
The rated voltage of the high voltage side shall not be less than the maximum test voltage of the subject, and the rated current shall not be less than the maximum capacitance current of the subject.
The formula for calculating the capacitance current of the tested product and the required capacity of the test transformer is:
I = 2πf Cx U x 10-6
U I = 2π f Cx U 2 x 10-9
Where I - capacitance current of the subject, A; f - Power supply frequency, Hz;
Cx - subject capacitance, μF; U - test voltage RMS, V;
Se - Rated capacity required for test transformer, KVA
The capacitance Cx of the subject can be measured by the AC bridge. The commonly used electrical capacity of the subject is selected according to the following table
