基于频谱分析的船载供电线路防雷保护装置设计
资料介绍
针对常规装置对船载供电线路绝缘保护效果不理想、防电冲击力大、抗干扰能力弱等问题,提出并设计了一种基于频谱分析的防雷保护装置。对前级防护电路进行分等级优化,同时采用二级防电管对电路结构进行简化,并在装置退耦元件的两端设置最大通过电流值;通过确定装置的防护范围,对其防雷水平进行计算,再设置合理的装置间隔,实现船载供电线路的防雷保护。仿真实验结果表明,基于频谱分析的防雷保护装置能够有效降低线路的防电冲击力,增强线路的抗干扰能力,达到理想的防雷、防电、绝缘保护效果,具备极高的鲁棒性。
Aiming at the problems of poor insulation protection effect of conventional devices on ship-borne power supply lines, large anti-electric shock force and weak anti-interference ability, a lightning protection device based on spectrum analysis is proposed and designed. At the same time, the structure of the circuit is simplified by using two-stage anticurrent tube, and the maximum current value is set at both ends of the decoupling element of the device. By determining the protection range of the device, the lightning protection level is calculated, and then the reasonable device interval is set to realize the lightning protection of the ship-borne power supply line. The simulation results show that the lightning protection device based on spectrum analysis can effectively reduce the electric shock of the line, enhance the anti-interference ability of the line, achieve the ideal lightning protection, anti-electricity, insulation protection effect, and have very high robustness.
