电力系统用串联电容器.第1部分:总则

[中文适用范围]： IEC 60143 的这一部分适用于与交流输电或配电线路或构成频率为 15 Hz 至 60 Hz 的交流电源系统一部分的电路串联使用的电容器单元和电容器组。该标准的主要重点是传输应用。串联电容器单元和组通常用于高压电力系统。本标准适用于整个电压范围。本标准不适用于自愈金属化介电型电容器。以下电容器，即使与电路串联，也不包括在本标准范围内： 用于感应发热设备的电容器 (IEC 60110-1)；用于电机应用等的电容器（IEC 60252（所有部分））；用于电力电子电路的电容器（IEC 61071）；放电灯电容器（IEC 61048 和 IEC 61049）。对于标准类型的附件，例如绝缘子、开关、互感器、外部熔断器等，请参阅相关的 IEC 标准。注 1：对于受内部熔断器保护的电容器的附加要求以及内部熔断器的要求，请参见 IEC 60143-3。另请参见附录 C。 注 2 对于由外部熔断器保护的电容器的附加要求以及外部熔断器的要求，请参见附录 A 和附录 C。 注 3 串联电容器附件（火花隙、 IEC 60143-2 已修订并于 2012 年完成。串联电容器内部熔断器的单独标准 IEC 60143-3已修订并于 2013 年完成。 注 4：有关无熔丝电容器组和无熔丝电容器组的一些信息见附录 C。制定有关性能、测试和评级的统一规则；制定具体的安全规则；作为安装和操作的指南。 [外文原描述]： IEC 60143-1:2015 applies both to capacitor units and capacitor banks intended to be used connected in series with an a.c. transmission or distribution line or circuit forming part of an a.c. power system having a frequency of 15 Hz to 60 Hz. The primary focus of this standard is on transmission application. The series capacitor units and banks are usually intended for high-voltage power systems. This standard is applicable to the complete voltage range. This standard does not apply to capacitors of the self-healing metallized dielectric type. The following capacitors, even if connected in series with a circuit, are excluded from this standard: - capacitors for inductive heat-generating plants (IEC 60110-1); - capacitors for motor applications and the like (IEC 60252 (all parts)); - capacitors to be used in power electronics circuits (IEC 61071); - capacitors for discharge lamps (IEC 61048 and IEC 61049). For standard types of accessories such as insulators, switches, instrument transformers, external fuses, etc. see the pertinent IEC standard. The object of this standard is: - to formulate uniform rules regarding performance, testing and rating; - to formulate specific safety rules; - to serve as a guide for installation and operation. This fifth edition cancels and replaces the fourth edition, published in 2004. This edition constitutes a technical revision. The main change with respect to the previous edition is that the endurance test has been replaced by an ageing test because voltage cycling is already performed in the cold duty test. The guide section has been expanded regarding long line correction and altitude correction. In addition the insulation tables and references to other standards have been updated. Keywords: a.c. transmission or distribution line, capacitor units and banks for high-voltage power systems The contents of the corrigendum of April 2017 have been included in this copy.
