Electrification Test Device and Method for Two-Phase Flow

Phase change cooling system is a key component of high power electronic equipment, and its insulation performance plays a very important role in the stable operation of power system. Aiming at the problem of two-phase flow charging in the phase change cooling system, a device for generating and detecting two-phase flow charging is designed in this paper, and a test method for two-phase flow and single-phase flow charging is proposed. First of all, it can generate two-phase flow, control the two-phase flow in a certain boiling state to measure the flush current, simulate the actual condition of phase change media in high-power power electronic equipment. Secondly, it can measure the charging of single-phase liquid flow at the same time and compare the charging degree of the same phase change medium in the two-phase state and the monomeric state. Finally, the specific operation process of charging the two-phase flow and single-phase flow is given.
