标准摘要
[中文适用范围]： IEC 62271 的这一部分适用于电压为 72.5 kV 及以上的系统上以 50 Hz 和 60 Hz 频率运行的高压交流断路断路器。该标准确定了 IEC 60694、IEC 62271-100 和 IEC 62271-102 标准的哪些要求适用。它还给出了针对这些设备的附加要求。该标准涵盖了一种断路器，当处于分闸位置时，该断路器同时满足断路器和隔离开关的要求。由于不同功能的需求之间存在相互作用，因此有必要考虑需求的标准化。该标准详细说明了隔离断路器的要求，并确定了这些要求与分立式断路器和隔离开关的单独要求的不同之处。注：隔离断路器的设计实例参见附录 A。 [外文原描述]： This part of IEC 62271 applies to high-voltage alternating current disconnecting circuit-breakers for operation at frequencies of 50 Hz and 60 Hz on systems having voltages of 72,5 kV and above. This standard identifies which requirements of IEC 60694, IEC 62271-100 and IEC 62271-102 standards are applicable. It also gives the additional requirements specific to these devices. This standard covers a circuit-breaker which, when in the open position, satisfies the requirements of both a circuit-breaker and a disconnector.
