Zusammenfassung: | A method for calculating explosion impact excitation of an oil-immersed transformer based on actual gas comprises the following steps: step 1, calculating arc energy of arc discharge in the transformer according to the measured arc length, arc current and discharge time of arc discharge in the transformer; 2, calculating the temperature of the gas in the transformer oil after absorbing heat energy; 3, introducing a Van der Waals equation to describe the state of gas in the transformer oil, and calculating the internal pressure of the gas in the transformer oil according to the conversion relation between the molar volume and the molar mass of the gas, so as to obtain the internal and external pressure difference of the gas in the transformer oil; and 4, calculating the impact excitation generated by the explosion of the oil-immersed transformer in combination with the impact response function of the Gaussian filter. According to the method for calculating the explosion impact excitation of the oil-immersed tr |
