Testing transformer is the essential test equipment for the power equipment test and preventive test. Requirements for the voltage grade of the testing transformers become increasingly higher with the development of the electric power industry of our country, and the traditional oil-immersed testing transformers are failing to meet the site work requirements, whether in the volume, weight or performance.
With the progresses of our country in the basic scientific research, the new medium SF6 gas has been pushed to the application filed of the power equipment by new material and new process application. SF6 is widely applied as a new insulating medium due to its excellent insulating property and arc quenching performance and noninflammability.
Apply to power equipment inspection and preventive test. RSYDQ series are essential equipment during electrical equipment tests and preventive tests. With the development of China's power industry, people required higher about the voltage class of testing transformer, and the traditional oil / dry type test transformer cannot meet the requirement in volume, weight, and functions.
