  • 국내공항의 경우 전기설비의 중요도에 비해 이에 대한 설계기준이나 표준지침이 제대로 갖추어지지 않아 오늘날 공항의 건설, 공항시설의 확충, 증설시에 체계적이고 표준화된 수 배전설비를 갖추기 어려운 실정이다. 따라서, 본 논문에서는 국내공항을 Code화에 의한 4등급으로 분류하고 수 배전설비에 대한 정의 및 적용범위를 설정한 후 기존 공항의 수 배전설비에 대한 문제점을 분석하고 공항 수 배전설비 제어시스템 기준과 공항 등급별 3단계 방안을 제시하여 공항등급별 표준 단선 결선도를 작성한 다음 단선 결선도에 따른 공항 수 배전설비 시설기준을 제시한다.

  • The occurrence of a corona is that electrical discharge due to the heterogeneity that occurs when an electrical field is concentrated in an electrode due to a cusp formed on said electrode. Wire treatment at the end of a 154[kV] dead end clamp for end users accelerates the occurrence of corona, which in turn leads to power loss and noise. In this study, the characteristics of the corona which occurs between porcelain insulators and support clamps of overhead lines used in 154[kV] power receiving facilities for end users were investigated. The corona, which cannot be identified by one common method, was measured utilizing a UV image camera. A risk assessment for fire damage and its status was suggested. The stress distribution of the electrical field by length of bare wire was suggested by means of the finite element method(FEMLAB). As a result, it was found to affect a porcelain insulators. These results can be utilized for the enhancement of clamp installation and safety in power facilities.
