Abstract

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 it is important to set properly and to calculate the short-circuit voltage in its design to ensure the manufacturing cost of the transformer and safe operation of the transformer. In this paper, we analyzed and compared the calculation methods of leakage reactance traditionally used in transformer design and propose an approach using ANSYS Maxwell to calculate the leakage reactance more accurately. It can investigate an electromagnetic phenomenon happening in the transformer intuitionally and can perform the simulation for the practice operating process and the short-circuit test process directly using the ANSYS Maxwell program. In the post-processing, when ANSYS Maxwell has completed a solution because it can apply the various mathematical functions and some of these functions can operate along an entire curve, for example, dev, min, max, integ, avg, rms, and so on, it is afforded every facility for the analysis of the engineering calculations. The accuracy of the proposed method is verified by comparing the proposed method with conventional leakage reactance calculation methods and analyzing the error of the experimental results.
