摘要
随着航空工业发展,出现了变频电源。过电流保护装置为适应变频电源要求,需在理论和试验上分析和研究变频对其的影响。研究结果表明,在一定范围内,变频对热、过电流保护装置和电子型过电流保护装置影响较小。
Along with the aviation industry development, the frequency conversion power was emerging. Over current protection device should adapted to the frequency conversion power, it was necessary to analyze and research on the influence of frequency conversion theoretically and experimentally. The research indicates that, in a certain scope, frequency conversion has little influence on the heat-type over current protection device and electronic-type over current protection device.
