30kVA x3 300kV Cascaded Oil-Immersed Test Transformer

Product features:

First, it adopts a 3-level cascaded series connection structure, which can realize the output of 300kV ultra-high voltage while ensuring the compactness of the equipment, avoiding the problem of oversized volume of single high-voltage transformers. Second, each single unit adopts natural oil cooling, which reduces the energy consumption and maintenance cost of the equipment. Third, it is equipped with a synchronous control system, which can ensure that the output voltage of each cascaded unit is consistent, ensuring the accuracy and stability of the test data. In addition, it has a comprehensive safety protection system, including overvoltage protection, overcurrent protection and interlock protection between cascaded units, which effectively ensures the safety of the testing process. It can be disassembled into three independent units, which is convenient for transportation and installation in complex scenarios.
