DC 급전케이블 지락사고 보호방안에 관한 연구
The study on the prevention of DC feeder line cable grounding fault
- 발행 : 2008.11.13
초록
This study provides review and improvement plans for the possible problems caused when the CV cable is used as a positive feeder line which supplies power from the DC HSCB (high-speed circuit breaker) to the catenariesin Seoul Metro which is using direct-current feeder method. In detail, this study contributes to stabilizing the power line by triggering a protective device by instantly detecting potential rise which happens when grounding fault occurs in non-grounding type CV cable shield.
