摘　　要：工作电压是指设备在正常工作的条件下,所考虑的绝缘或元器件上所承受到的或能够承受到的最高电压。工作电压的测量结果影响到电气间隙、爬电距离和绝缘穿透距离、抗电强度等项目的试验限值及试验参数。本项目基于数字示波器DS07032A,对示波器探头类型、耦合方式、L-N极性反转、示波器扫描模式等影响因素进行比对分析,对工作电压的峰值电压和有效值电压进行测试,研究各因素对工作电压准确测量的影响。Working voltage refers to the highest voltage that the insulation or components under consideration bear or can bear under normal working conditions.The measurement results of working voltage affect the test limits and test parameters of electrical clearance,creepage distance,insulation penetration distance and electrical strength.Based on the digital oscilloscope ds07032a,this project compares and analyzes the influencing factors such as probe type,coupling mode,L-N polarity reversal and oscilloscope scanning mode,tests the peak voltage and RMS voltage of working voltage,and studies the influence of various factors on the accurate measurement of working voltage.
