电缆是电力传输和分配系统中不可或缺的组成部分。在电力系统中,电缆的额定电压和短路温度限制是非常重要的参数。因此,IEC 61443:1999/AMD1:2008 标准规定了额定电压高于30 kV(Um=36 kV)的电缆的短路温度限制。
该标准的修订版是对原版的补充,旨在提高电缆的安全性和可靠性。修订版中,对电缆的短路温度限制进行了更加详细的规定,以确保电缆在短路情况下能够正常运行,并且不会对人员和设备造成危害。
IEC 61443:1999/AMD1:2008 标准规定了额定电压高于30 kV(Um=36 kV)的电缆的短路温度限制。在短路情况下,电缆的温度不应超过规定的限制值。这样可以确保电缆在短路情况下能够正常运行,并且不会对人员和设备造成危害。
此外,该标准还规定了电缆的额定电压和短路温度限制之间的关系。在设计和选择电缆时,必须考虑到这些参数,以确保电缆能够在正常运行和短路情况下都能够满足要求。
总之,IEC 61443:1999/AMD1:2008 标准是电缆设计和选择中非常重要的参考标准。它规定了额定电压高于30 kV(Um=36 kV)的电缆的短路温度限制,以确保电缆在短路情况下能够正常运行,并且不会对人员和设备造成危害。
