用于电子和电信设备的变压器和电感器 - 测量方法和测试程序

[中文适用范围]： 本文件描述了一系列用于确定用于电子和电信设备的变压器和电感的显著参数和性能特性的测试方法。这些测试方法主要针对可用于此类元件任何规格的所有类型的电子应用中使用的变压器和电感。尽管这些测试可能对用于公用事业、工业等电力分配应用的其他类型的变压器有用，但本文件中讨论的测试可以补充或补充测试，但不旨在取代变压器标准中的测试。其中一些测试旨在使产品符合特定应用的要求，而另一些则是用于制造和客户验收测试的测试实践。此处描述的方法包括电子变压器和电感行业中常用的参数：电强度、电阻、功率损耗、电感、阻抗、平衡、变比以及许多其他较少使用的参数。 [外文原描述]： IEC 61007:2020 describes a number of tests for use in determining the significant parameters and performance characteristics of transformers and inductors for use in electronics and telecommunication equipment. These test methods are designed primarily for transformers and inductors used in all types of electronics applications that can be involved in any specification for such components. Even though these tests can be useful to the other types of transformers used in power distribution applications in utilities, industry, and others, the tests discussed in this document can supplement or complement the tests but are not intended to replace the tests in standards for transformers. Some of the tests described are intended for qualifying a product for a specific application, while others are test practices used for manufacturing and customer acceptance testing. The test methods described here include those parameters most commonly used in the electronics transformer and inductor industry: electric strength, resistance, power loss, inductance, impedance, balance, transformation ratio and many others used less frequently. This edition includes the following significant technical changes with respect to the previous edition: a) scope: the application of the scope of IEC 61007 was extended; b) Clause 2: added new references and updated the references; c) Clause 3: new definitions were added in 3.3, and in 3.7 the voltage-time product was redefined; d) test procedures were updated; e) environmental test procedures: new references were added; f) Annexes A to G were added. The contents of the corrigendum of June 2021 have been included in this copy.
