摘　　要：传统漆包线绕制变压器用作本质安全可靠隔离器件时,存在评定方法不足的问题,因此引出将平面变压器用作可靠隔离器件的思路,并针对平面变压器的特点,提出一种采用计算分析代替型式试验的新型评定方法,同时给出隔离间距的判定方法。理论分析表明,该种新型评定方法可用于判断平面变压器的可靠隔离性能。The insufficiencies in the evaluation methods for traditional enameled wire-wound transformers used as reliable isolation devices in intrinsic safety applications are discussed in this paper.The article introduces the concept of using planar transformers as reliable isolation devices and,in light of their unique characteristics,proposes a novel evaluation method that replaces type testing with computational analysis.Additionally,a method for determining isolation spacing is provided.Theoretical analysis indicates that this new evaluation method can be employed to assess the reliable isolation performance of planar transformers.
