电子电气产品的插头放电测试

研究插头放电的测试方法,比较了不同标准判定的差异,一般考察特定时间的电压或电压下降到特定值所需的时间。通过对相关测试结果的分析,发现由于很难在电压峰值切断电压,故理论值大于实测值。为减小探头阻抗对测试值的影响,所用探头电阻需尽量大,电容需尽量小。

Analysis of the plug discharge test of the electrical and electronic products

The plug discharge test method is studied here. And the differences of the judge in different standards is compared. There are two methods：investigating the voltage at a specific time or investigating the time needed when the voltage drop to a specific value. Through the analysis of the relevant test results, it is founded that the theoretical values are greater than the measured values because of the difficulty in the cutting off the voltage at the peak voltage. To reduce the influence of probe impedance values to the test, the probe resistance should be greater and the capacitance should be smaller as far as possible.
