Title (EN) UNINTERRUPTIBLE BYPASS METHOD FOR AN UNDERGROUND POWER LINE USING AN EXTENSION ELBOW HAVING A SPLIT CONNECTION FUNCTION

Abstract: front page image
(EN)The present invention relates to an uninterruptible bypass method for an underground power line, which enables uninterruptible maintenance for replacing of devices such as transformers, switches or the like, and cables of the underground power line. More particularly, the extension elbow of the present invention has a split connection function which enables the uninterruptible bypass of the underground power line, while conventional elbow connectors are only connectible to the ends of underground cables interconnecting switches and transformers of the underground power line. When the uninterruptible replacement of switches, transformers, and cables of the underground power line is performed when the extension elbow of the present invention is installed in lieu of conventional elbows for the new construction of an underground power line, or when conventional elbow connectors are uninterruptibly replaced in conventional underground power lines by extension elbows using a sequential separation and connection method, the extension elbow of the present invention enables the uninterruptible installation of bypass cables for temporary power transmission, and thus enables remarkably safe and quick uninterruptible installation. Further, the uninterruptible bypass method for the underground power line using the extension elbow having a split connection function according to the present invention is a novel and remarkably safe and economically advantageous underground wiring technique which enables the installation and construction of an underground power line to be conducted uninterruptibly during the daytime, as compared to conventional systems in which the installation and construction of an underground power line is mostly performed in an interrupted manner during nighttime, which is dangerous and inefficient.
(FR)La présente invention concerne un procédé de bypass sans coupure pour une ligne d'alimentation souterraine, qui permet la maintenance sans coupure pour le remplacement de dispositifs tels que des transformateurs, commutateurs ou analogues, et des câbles de la ligne d'alimentation souterraine. Plus particulièrement, le coude de rallonge de la présente invention présente une fonction de raccordement séparé qui permet le bypass sans coupure de la ligne d'alimentation souterraine, alors que des raccords coudés classiques sont uniquement raccordables aux extrémités de câbles souterrains reliant entre eux des commutateurs et des transformateurs de la ligne d'alimentation souterraine. Lorsque le remplacement sans coupure de commutateurs, transformateurs et câbles de la ligne d'alimentation souterraine est mis en oeuvre quand le coude de rallonge de la présente invention est installé à la place de coudes classiques pour la nouvelle construction d'une ligne d'alimentation souterraine, ou quand des raccords coudés classiques sont remplacés sans coupure dans des lignes d'alimentation souterraines classiques par des coudes de rallonge à l'aide d'un procédé séquentiel de séparation et de raccordement, le coude de rallonge de la présente invention permet l'installation sans coupure de câbles de bypass pour la transmission temporaire d'énergie, et ainsi permet d'obtenir une installation sans coupure remarquablement sûre et rapide. En outre, le procédé de bypass sans coupure de la ligne d'alimentation souterraine utilisant le coude de rallonge présentant une fonction de raccordement séparé selon la présente invention constitue une technique de câblage souterrain nouvelle ainsi que remarquablement sûre et économiquement avantageuse qui permet l'installation et la construction d'une ligne d'alimentation souterraine sans coupure pendant la journée, comparé à des systèmes classiques dans lesquels l'installation et la construction d'une ligne d'alimentation souterraine est en général mise en oeuvre avec coupure pendant la nuit, ce qui est dangereux et inefficace.
(KO)본 발명은 지중배전선로의 변압기와 개폐기 등의 기기 및 케이블 교체를 비롯한 유지 보수를 무정전으로 시공하기 위한 지중배전선로의 무정전 바이패스 시공법에 관한 것으로, 더욱 상세하게는 지중배전선로용 개폐기와 변압기를 연결하기 위한 지중케이블의 단부에 접속만 가능한 기존의 엘보우 접속구 대신 지중배전선로의 무정전 바이패스 시공을 가능하게 하는 별도의 분기접속기능을 갖는 익스텐션 엘보우가 지중배전선로의 신규 건설시 적용 설치된 상태 또는 기존 지중선로의 경우 순차적인 분리 연결 방법에 의해 무정전 상태로 기존 엘보우 접속구를 익스텐션 엘보우로 교환 설치한 상태에서 지중배전선로용 변압기와 개폐기 및 케이블의 교체 시공 등 무정전 시공을 하는 경우 상기의 익스텐션 엘보우를 이용하여 임시 송전용 바이패스케이블을 무정전으로 설치하여 매우 안전하면서도 신속한 무정전 시공이 이루어질 수 있게 함은 물론 종전에 대부분의 지중배전선로에 대한 작업이 심야 할증을 적용하여 야간에 정전 작업으로 시공하여 위험하고 비능률적으로 이루어졌던 것을 무정전 상태에서 주간에 해당 공사에 대한 모든 작업이 이루어지게 하여 매우 안전하고 경제적인 특징의 지중배전 신기술로서 분기접속기능을 갖는 익스텐션 엘보우를 이용한 지중배전선로의 무정전 바이패스 시공법에 관한 것이다.
