Abstract
국내의 한국전력망 또는 민간 산업공장에서는 노후선로 교체 또는 부하 증가에 의한 송전용량 증대를 위한 가공전선 교체 작업으로 인하여 매년 수백 톤의 폐가공전선이 발생되고 있는 실정이다. 최근 경제적인 측면과 환경적인 측면, 효율성에 관한 측면에서 전선의 재활용 기술이 폭넓게 연구되고 있다. 본 연구에서는 폐전선의 재활용 기술에 대한 특허와 논문을 분석하였다. 분석범위는 1975년 ~ 2011년까지의 미국, 유럽연합, 일본, 한국의 등록/공개된 특허와 SCI 논문으로 제한하였다. 특허와 논문은 키워드를 사용하여 수집하였고, 기술의 정의에 의해 필터링 하였다. 특허와 논문의 동향은 연도, 국가, 기업, 기술에 따라 분석하여 나타내 보았다. There are generated the hundreds of tons of waste electric wire per year due to replace for increase transmission capacity and/or replacement of old electric wire by Korea's national power grid and/or private industrial factories. Recently, the wire recycling technologies studied extensively in terms of effieiency by of economic aspects and environment aspects. In this paper, the patents and papers for the recycling technologies of spent electric wire were collected and analyzed. The range of search was limited in the open patents of USA (US), European Union (EP), Japan (JP), Korea (KR) and SCI journals from 1975 to 2011. Patents and journals were collected using key-words searching and filtered by filtering criteria. The trends of the patents and journals were analyzed by the years, countries, companies, and technologies.
