摘　　要：针对超速保护模块电源单元保险丝烧毁问题,实测出不同上电方式的启动冲击电流波形。从电压、电流等方面对保险丝烧毁机理进行分析,本文提出了一种超速保护模块过流导致保险丝烧毁分析方法,从瞬态能量和稳态电流两方面考虑,对不同贴片保险丝机理分析,与实测的冲击电流波形进行对比分析。此方法指导了电路设计中保险丝选型,提高产品的容错能力。This article addresses the issue of fuse burnout in the power unit of an overspeed protection module.It measures the start-up inrush current waveforms under different power-on methods.The mechanism of fuse burnout is analyzed from aspects such as voltage and current.The article proposes an analysis method for fuse burnout caused by overcurrent in the overspeed protection module,considering both transient energy and steady-state current.It analyzes the mechanisms of different surface-mount fuses and compares them with the measured inrush current waveforms.This method guides the selection of fuses in circuit design,improving the fault tolerance of the product.
