摘要:
基于开关柜电压在电弧故障时电压变化率在零区时最大的规律,研制一种弧声信号的电弧预警保护系统.根据电弧发生燃弧现象之前会有比较明显的弧声信号的情况,用相应的声音传感器将电弧声音从复杂的背景噪声中提取出来,经过信号调理电路和计算机软件系统的运算,设定合适的幅值阈值,实现对故障电弧的报警.实验结果表明,设计的电弧预警保护系统效果良好.
Abstract:
An arcing early warning and protective system using arc sound signa is designed,based on zero zone’s largest rule of the change rate of switchboard voltage in arc fault.According to the fact that there exists arc sound more obviously before its burning,the arc sound was picked up from the complicated background noise using the corresponding sound sensors.Then,the appropriate amplitude threshold values were established by signal conditioning circuits and the calculation of computer software systems to realize the early warning of fault arc.Experimental results have proven the good effects of the designed arcing early warning and protective system.
