With the rapid development of the whole society, the computer is also constantly developing, but the numerical calculation of the whole process of the S20 oil-immersed transformer wave has results, only a reasonable selection of the calculation numerical model and method are required, and the accuracy of the calculated results can meet the standards of architectural engineering design. And within a certain range, the scientific and reasonable layout and planning of the S20 oil-immersed transformer and other parts can greatly facilitate the design of the S20 oil-immersed transformer, so as to ensure the stability of operation.

When using the numerical method to measure the winding resistance wave of the S20 oil-immersed transformer, we can generally divide the winding resistance of the S20 oil-immersed transformer into multiple modules, and each module is replaced by an equivalent power supply circuit, and the power supply circuit covers an inductance and longitudinal capacitance, a voltage capacitance to the ground or the capacitance between the winding resistance, and there are transformers between the inductors of each module. And collect the chain Internet as the equivalent power supply circuit of the S20 oil-immersed transformer, and the accuracy of the process obtained can fully meet the needs of the actual construction project.

The first step in the calculation of the whole process of the wave is to do a good job in the calculation of network parameters such as inductance, capacitance and resistor, but the accuracy of these parameters has a great impact on the results obtained from the calculation of the wave flow, but for the calculation of inductance, the better digital model is the physical model of the infinite length of the core column, but there are also many calculation methods.
