摘要
由于导体的运行载流量与导体绝缘层耐受温度成正比,而导体的耗能自损又与导体的温度相关,他们在配电系统不同的工作温度下会产生怎样的损耗,在本文中我们作出分析,以指导电力设计导线的选型。
Because carrying capacity of the conductor current is proportional to the temperature of the conductor insulating layer＇s tolerance, moreover , consuming energy of conductor to weaken itself is also related to the conductor＇s temperature, they will have different loss under the different operating temperature of distribution system of electrical power. There fore We should fully consider the conductor＇s temperature influence on its performance in the course of conductor design.
