标准范围

IEC 62271-109:2008适用于交流电。串联电容器旁路开关设计用于室外安装，并在电压高于52 kV的系统上以50 Hz和60 Hz的频率运行。它仅适用于三相系统中使用的旁路开关。本标准也适用于旁路开关的操作装置及其辅助设备。第二版取消并取代了2006年出版的第一版，构成了技术修订。本标准应与IEC 62271-100和IEC 62271-1（2007）一起阅读，除非本标准中另有规定。与上一版相比的主要变化如下:-旁路测试任务已经分开。-审查了试验参数适用性的等效性。-重新计算并优化了插入测试工作期间的恢复电压波形。关于恢复电压计算的解释性说明见附录F。-撤销电气耐久性等级BP2。此类器械现已列入资料性附件E。-增加了附录D，其中给出了典型旁路开关额定值的示例。

IEC 62271-109:2008 is applicable to a.c. series capacitor by-pass switches designed for outdoor installation and for operation at frequencies of 50 Hz and 60 Hz on systems having voltages above 52 kV. It is only applicable to by-pass switches for use in three-phase systems. This standard is also applicable to the operating devices of by-pass switches and to their auxiliary equipment. This second edition cancels and replaces the first edition, published in 2006, and constitutes a technical revision. This standard is to be read in conjunction with IEC 62271-100 and IEC 62271-1 (2007), to which it refers and which is applicable, unless otherwise specified in this standard. The main changes with respect to the previous edition are listed below:
- By-passing test duty has been split.
- Equivalence regarding applicability of test parameters were reviewed.
- Recovery voltage waveshape during insertion test duty has been recalculated and optimized. An explanatory note on the calculation of the recovery voltage is given in Annex F.
- Withdrawal of the electrical endurance class BP2. Such devices are now covered in informative Annex E.
- Addition of Annex D which gives examples of typical by-pass switch ratings.
