摘要
文中提出导线经济电流密度的几种计算公式,结合计算实例,指出现行导线经济电流密度偏大,造应我国平均线损率过高,运行不经济等问题,并提出相应的建议,可供主管部门及设计工作者参考。
This paper has introduced several formulas to ealcul-ate economic current density of wire, and pointed out, with practical exa-mple, that present wire economic current density is on the large side andit makes average wire loss rate overhigh and operation in out of economy.At the end of this paper, some effect improvement methods was proposed.
