摘要
IEC60943技术报告是由IEC32熔断器技术委员会编制,并于1998年发布的。技术报告旨在指导评估稳定状态下载流电器设备组件的温升容许值。技术报告提供了触头接触电阻的计算和基本老化机理;触头和接线端子的温度和温升计算;不同组件,特别是触头,接线端子和连接它们的导体的最大容许温度和温升;IEC各产品委员会确定最大容许温度和温升必须遵守的主要程序。
IEC60943 technical report was prepared by IEC technical committee 32:Fuses, and was issued in 1998.Technical report is intended for guidance in estimating the permissible values for temperature rise of component parts of electrical equipment carrying current under steady state conditions. Technical report supplies the calculation of contact resistance of electric contacts and the basic ageing mechanisms of contacts; the calculation of temperature and temperature rise of contacts and connection terminals; the maximum permissible temperature and temperature rise of various components, in particular the contacts, the connection terminals and the conductions connected to them ; the general procedure to be followed by IEC product committees for specifying the permissible temperature and temperature rise.
