[0030] specific implementation plan
[0031] Because the temperature and electric field of the cable during operation are different at different insulations, and the parameters of the cable insulation such as DC conductance and complex dielectric constant change with temperature, electric field, frequency and other factors. Therefore, the equivalent resistance and capacitance of the cable insulation to the ground will be affected by the operating state. In order to analyze the cable leakage current response under different operating conditions, it is necessary to build a cable model under the action of electrothermal coupling.
[0032] The method for dynamic analysis of leakage current of mining XLPE cables involved in the present invention will be described in detail below in conjunction with the accompanying drawings and implementation cases.
