전력구내 지중케이블 강제냉각에서의 적정냉각구간에 관한 연구
A Study on the Optimum Cooling Span of the Underground Power Transmission Cable Equipped by a Forced Cooling System
- 발행 : 1990.02.01
초록
The forced cooling system has been widely applied to passing more electric current in the underground power transmission cable technology. In this paper, the optimum cooling span of the in-trough-indirect water cooling method within an electric tunnel was investigated. A parametric study was performed for the cable currents, the coolant flow rates, and the coolant inlet temperatures. As a result, the temperature of the inlet air has been found as the most important parameter in determination of the optimum cooling span.
