IEC/TR 62271-306:2012（E）适用于设计用于室内或室外安装的交流断路器，以及在电压高于1000 V的系统上以50 Hz和60 Hz的频率运行的交流断路器。本技术报告涉及指定和应用高压断路器、断路器开发工程师、，测试站的工程师，以及参与标准化的工程师。其目的是提供与标准中的事实和数字有关的背景信息，并为高性能材料的规范提供依据- 电压断路器。因此，其范围将涵盖IEC 62271-100和IEC 62271-1以及高压断路器相关标准和技术报告的解释、解释和应用。

IEC/TR 62271-306:2012(E) is applicable to a.c. circuit-breakers designed for indoor or outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 1 000 V. This technical report addresses utility, consultant and industrial engineers who specify and apply high-voltage circuit-breakers, circuit-breaker development engineers, engineers in testing stations, and engineers who participate in standardization. It is intended to provide background information concerning the facts and figures in the standards and provide a basis for specification for high-voltage circuit-breakers. Thus, its scope will cover the explanation, interpretation and application of IEC 62271-100 and IEC 62271-1 as well as related standards and technical reports with respect to high-voltage circuit-breakers.
