摘要
电子电气产品的抗电强度试验是产品型式评价中的基本试验内容。理解抗电强度试验的目的和原理,了解材料绝缘、介电击穿的原理,能够让标准制定者和实施者加深对试验的认识,帮助试验人员正确实施抗电强度试验。合理设置试验仪的失效电流门限,可以减少对试验结果的误判,提高试验效率,保护试验仪器与受试设备。另外还介绍了一些抗电强度试验中的小技巧与注意事项。
The electric strength test of electrical and electronic products is a basic test item in the product type evaluation.Understanding the purpose and function of the electric strength test,understanding the principle of material insulation and dielectric breakdown,can help standard enactors and testers to deepen their understanding of the test,and help testers to correctly implement the electric strength test.Predictive setting of the testdevice’s breakdown current threshold can reduce misjudgment of test results,improve test efficiency,and protect test equipment and equipment under test.In addition,some tips and precautions in the electric strength test are also introduced.
