摘　　要：在检测电容型验电器电压时,待检测验电器所处环境的电场分布存在差异,检测结果精准度较低,为此提出基于传感信号响应的电容型验电器电压智能检测方法。利用SL-AV81-5N端子输入型单相交流电压声频传感器采集电容型验电器的状态信号,结合频段信号不同状态下SL-AV81-5N信号的响应模式特点,对待检测验电器输出频段信号表现出较弱和较强时的电压参数进行差异化计算。测试结果中,验电器电压的检测精准度始终稳定在0.95以上。When detecting the voltage of a capacitive electroscope,the difference in the electric field distribution of the environment in which the tested appliance is located results in low accuracy of the detection results.Therefore,an intelligent voltage detection method for capacitive electroscope based on sensing signal response is proposed.Using the SL-AV81-5N terminal input single-phase AC voltage audio frequency sensor to collect the status signal of the capacitive electroscope,combined with the response mode characteristics of the SL-AV81-5N signal under different states of the frequency band signal,the voltage parameters when the output frequency band signal of the electroscope shows weak and strong are differentiated and calculated.In the test results,the detection accuracy of the electroscope voltage is always stable at 0.95 or above.
