摘要
对直流输电接地电极的发热进行了分析,在计算过程中考虑了焦炭的隔热及老化对接地电极发热的影响,同时也考虑了端部效应。
The analysis is done on the problem of overheating of the earthing electrode of DC transmission line caused by heat-insulating and ageing of the coke around the electrode, and at the same time, the end effect of the electrode on overheating is considered.
