标准摘要
[中文适用范围]： 本报告旨在为估算在稳态条件下载流电气设备部件的允许温度和温升值提供指导。本报告适用于电气功率连接及其邻近材料。本报告关注通过连接处的电流的热效应，因此其应用没有限制电压。本报告仅在引用适当的产品标准时才适用。本报告内容在标准中的使用范围和方式由各个技术委员会负责。当本报告规定“允许”值时，是指相关的产品标准所允许的值。本报告旨在提供：关于电气接触结构及其欧姆电阻计算的一般数据；接触的基本老化机制；接触和连接端子的温升计算；各种部件（特别是接触、连接端子及其连接的导体）的最大“允许”温度和温升值；产品委员会在指定允许温度和温升值时应遵循的一般程序。 [外文原描述]： IEC/TR 60943:1998+A1:2009 is intended for guidance in estimating the permissible values for temperature and temperature rise of component parts of electrical equipment carrying current under steady state conditions. The present report is intended to supply: - general data on the structure of electric contacts and the calculation of their ohmic resistance; - the basic ageing mechanisms of contacts; - the calculation of the temperature rise of contacts and connection terminals; - the maximum "permissible" temperature and temperature rise for various components, in particular the contacts, the connection terminals and the conductors connected to them; - the general procedure to be followed by product committees for specifying the permissible temperature and temperature rise. This consolidated version consists of the second edition (1998) and its amendment 1 (2009). Therefore, no need to order amendment in addition to this publication.
