标准摘要
[中文适用范围]： 本报告旨在指导估算稳态条件下承载电流的电气设备零部件的温度和温升允许值。本报告适用于电力连接和与其相邻的材料。该报告关注的是通过连接的电流的热效应，因此其应用没有电压限制。本报告仅在适当的产品标准中引用时才适用。标准中使用本报告内容的程度和方式由各个技术委员会负责。本报告中提及的“允许”值均指相关产品标准允许的值。本报告旨在提供： - 关于电触点结构及其欧姆电阻计算的一般数据； - 触点的基本老化机制； ——触点和连接端子温升的计算； ——各种部件的最大“允许”温度和温升，特别是触点、连接端子和与其连接的导体； - 产品委员会规定允许温度和温升时应遵循的一般程序。 [外文原描述]： 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.
