Title:
DIRECT-CURRENT ARC SIMULATION METHOD AND APPARATUS, AND COMPUTER DEVICE AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/226113
Kind Code:
A1
Abstract:
The present application relates to a direct-current arc simulation method and apparatus, and a computer device and a storage medium. The method comprises: acquiring a magnetohydrodynamic model and a circuit model of a switch device; performing joint field-circuit coupling simulation on the magnetohydrodynamic model and the circuit model according to an initial arc current of the switch device, so as to update an arc current of the magnetohydrodynamic model of the switch device; and then acquiring the temperature and the air pressure in the magnetohydrodynamic model during the process of joint field-circuit coupling simulation. In the method, the change condition of a fluid motion state in an arc in a switch device is taken into consideration, such that the influence of an arc current of a direct current on a change in the air pressure and the temperature in the switch device during the switching-on and switching-off processes of the switch device can be determined.
