脉冲功率电源连续发射水冷模拟负载
Water-cooling simulated resistance for continuously launching pulsed power supply
摘要
Abstract
For the demand of continuous energy absorption of pulsed power supply,the proposal about cycle pulse power water-cooling simulated resistance with 1. 9 MA current levels was carried out.Given full consideration to the similarities between the water-cooling resistance and the actual electromagnetic emission resistance,the resistance network composed of 4 ×8 array of steel pipes was designed,which is convenient for realizing discharging assessment with different power combination.For the problem that 1. 9 MA level current can cause too large electromagnetic force,the three-dimensional finite element model of resistance was constructed.Electromagnetic force calculation and structure analysis of resistance were implemented to ensure the stability of resistance.The analysis on resistance temperature rise with the cooling ways of natural,gale and deionized water using thermal network was implemented.The results show that the way of deionized water cooling reaches the best performance. The resistance temperature can reach initial state when pulsed power supply continuously discharges,and the maximum temperature can reach 62. 5 ℃,which can satisfy the requirement of continuous discharging.A prototype of resistance was manufactured,and was used for two times discharging with 1. 9 MA current.The experimental result demonstrates good agreement with the theoretical analysis.The resistance structure runs well,which verifies the correctness of theoretical analysis.关键词
