IEC 62271-101:2021主要适用于IEC 62271-100范围内的交流断路器。它提供了通过综合方法测试交流断路器的一般规则，用于在IEC 62271-100:2021的7.102至7.111中描述的测试职责范围内的制造和分断能力。 实践证明，综合试验是按照IEC 62271-100的要求对高压交流断路器进行试验的经济、技术上正确的方法，相当于直接试验。 所描述的方法和技术是通常使用的那些。本文件的目的是建立合成试验和正确评价结果的标准。这种标准将建立测试方法的有效性，而不会对测试电路的创新施加限制。本第三版取消并取代了2012年出版的第二版和修正案1:20 17。本版构成技术修订版。 与第二版相比，此版本包括以下重大技术变更: a)与IEC 62271-100:2021第三版保持一致； b)使用用于合成试验的最新方法和技术更新本文件。

IEC 62271-101:2021 mainly applies to AC circuit-breakers within the scope of IEC 62271-100. It provides the general rules for testing AC circuit-breakers, for making and breaking capacities over the range of test duties described in 7.102 to 7.111 of IEC 62271-100:2021, by synthetic methods.
It has been proven that synthetic testing is an economical and technically correct way to test high-voltage AC circuit-breakers according to the requirements of IEC 62271-100 and that it is equivalent to direct testing.
The methods and techniques described are those in general use. The purpose of this document is to establish criteria for synthetic testing and for the proper evaluation of results. Such criteria will establish the validity of the test method without imposing restraints on innovation of test circuitry.
This third edition cancels and replaces the second edition published in 2012 and Amendment 1:2017. This edition constitutes a technical revision.
This edition includes the following significant technical changes with respect to the second edition:
a) alignment with the third edition of IEC 62271-100:2021;
b) update this document with the last methods and techniques used for synthetic tests.
