标准范围

IEC TR 63139:2018（E）与TC 34标准中的绝缘协调有关，并对工作电压的数学相加、电路之间的绝缘、保护性超低电压（PELV）的使用以及低压电源和控制线导体之间的绝缘进行了解释，以涵盖与LED光源和可控产品使用相关的新技术。它描述了如果发生第一故障，如何安排电源电压和工作电压的添加以评估系统中的电绝缘要求（例如爬电距离和间隙）。

IEC TR 63139:2018(E) is related to the insulation coordination in TC 34 standards and provides explanations on mathematical addition of working voltages, insulation between circuits, use of protective extra low voltage (PELV) and insulation between LV supply and control line conductors in order to cover new technologies associated with the use of LED light sources and controllable products.
It describes in which way the addition of supply voltages and working voltages can be arranged for an assessment of the electrical insulation requirements (e.g. creepage distances and clearances) in a system if a first failure occurs.
