An electrostatic precipitator is essential for thermal power plants, cement plants, chemical plants and mines. Its function is to clean the particulate dust contained in the smoke and gas that are discharged from the processes, thus improving the environmental pollution caused by them and improving the quality of air.
A high-voltage rectifier transformer, one of the most important parts of electrostatic precipitation equipment, is a kind of special transformer. The high-voltage rectifier transformer for electrostatic precipitation is a transformer operated under constantly varying load conditions, i.e., no-load, rated, and short-circuit conditions, and properly setting and accurately calculating the short-circuit voltage in its design is important to ensure efficient manufacturing cost and safe operation.
Yu Kwang Chol, a section head at the Faculty of Electrical Engineering, analyzed and compared the calculation methods of leakage reactance traditionally used in transformer design, and proposed an approach to calculate the leakage reactance more accurately using ANSYS Maxwell for two-winding transformers with different winding heights and a large number of windings.
He verified the accuracy of the proposed method by comparing it with conventional leakage reactance calculation methods and analyzing the error of the experimental results.
The result of the analysis shows that the ANSYS Maxwell program is a more precise and easy tool for calculating the leakage inductance and short-circuit voltage of transformers.
