额定电压1000V以上交流电力系统用并联电容器.第1部分:总则

[中文适用范围]： IEC 60871-1 的该部分适用于电容器单元和电容器组，特别是用于额定电压高于 1 000 V 的交流电力系统的功率因数校正，频率范围为 15 Hz 至 60 Hz。该部分也适用于用于电源滤波器电路的电容器。对于滤波器电容器，额外的定义、要求和测试见附录 B。对于内部熔断器保护的电容器以及内部熔断器的要求见 IEC 60871-4。对于需要外部熔断器保护的电容器及相关要求见附录 C。本标准不适用于自愈式金属化介质类型的电容器。本部分排除以下电容器：频率在 40 Hz 至 24 000 Hz 之间运行的感应加热厂用电容器（IEC 60110-1）；电力系统的串联电容器（见 IEC 60143 系列）；电机应用等的电容器（见 IEC 60252 系列）；耦合电容器和电容分压器（IEC 60358）；额定电压低至 1 000 V（含 1 000 V）的交流电力系统的并联电容器（见 IEC 60831 和 IEC 60931 系列）；用于荧光灯和放电灯的小型交流电容器（IEC 61048 和 IEC 61049）；用于电力电子电路的电容器（IEC 61071）；用于微波炉的电容器（IEC 61270-1）；用于抑制无线电干扰的电容器；用于交流电压叠加在直流电压上的电容器。附件如绝缘子、开关、仪器变压器、外部熔断器等，应符合相关 IEC 标准。本部分的目标如下：a) 制定关于单元和组的性能、额定值以及单元测试的统一规则；b) 制定具体的安全规则；c) 提供安装和操作的指南。 [外文原描述]： IEC 60871-1:2014 is applicable to both capacitor units and capacitor banks intended to be used, particularly, for power-factor correction of a.c. power systems having a rated voltage above 1 000 V and frequencies of 15 Hz to 60 Hz. This part of IEC 60871 also applies to capacitors intended for use in power filter circuits. The object of this part of IEC 60871 is as follows: - to formulate uniform rules regarding the performance and rating of units and banks, and the testing of units; to formulate specific safety rules; - to provide a guide for installation and operation. This fourth edition cancels and replaces the third edition published in 2005. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: - the overvoltage cycling test has been moved to this standard from the IEC 60871-2; - the ranges of the standardized values of the highest voltage for equipment have been modified; - for installations installed on altitudes above 1 000 m a correction factor to all insulation requirements has been introduced; - new standard insulation tables have been defined.
