标准范围

IEC 60252-1:20 10适用于用于连接到由频率高达并包括100Hz的单相系统供电的异步电动机的绕组的电动机电容器，以及用于连接到三相异步电动机的电容器，使得这些电动机可以由单相系统供电。本标准涵盖具有纸、塑料膜或两者组合电介质的浸渍或未浸渍电容器，金属化或带有金属箔电极，额定电压高达660 V（含660 V）。与上一版相比，此版本包括以下重大技术变更:-3.6中增加了“分段电容器”的定义；-第3条澄清了“操作类别”的定义，并参考统计数字加入了“可能寿命”的概念。9;-6.1中引入了以下措辞“高于额定电压运行将降低电容器的预期寿命”。-在第8条“标记”中增加了一些澄清，主要是针对小型电容器。

IEC 60252-1:2010 applies to motor capacitors intended for connection to windings of asynchronous motors supplied from a single-phase system having a frequency up to and including 100 Hz, and to capacitors to be connected to three-phase asynchronous motors so that these motors may be supplied from a single-phase system. This standard covers impregnated or unimpregnated capacitors having a dielectric of paper, plastic film, or a combination of both, either metallized or with metal-foil electrodes, with rated voltages up to and including 660 V. This edition includes the following significant technical changes with respect to the previous edition:
- the definition of "segmented capacitors" has been added in 3.6;
- the definition of "classes of operation" has been clarified, with the addition of the concept of "probable life" with reference to statistics, in 3.9;
- the following wording "Operation above the rated voltage will reduce the life expectancy of the capacitor" has been introduced in 6.1.
- some clarifications have been added to Clause 8, Marking, mainly for small capacitors.
