Zusammenfassung:The present invention relates to an uninterruptible distribution construction method for low-voltage lines, comprising: a first step of installing a branch device and a detection device at a predetermined location to perform uninterrupted power distribution construction on low-voltage lines; a second step of connecting a lead wire between a transformer of a mobile transformer train and a branch device connected to the transformer, and connecting a low-voltage cable between the branch device and an inspection circuit breaker; a third step of performing the inspection and then turning on a breaker of the inspection circuit breaker when the lead wire connection and the low-voltage cable connection are completed; a fourth step of separating an electric pole-side transformer and low-voltage wires and carrying out a main work of uninterruptible distribution construction for low-voltage lines, including transformer replacement and wire replacement, when the breaker of the inspection circuit breaker is turned on; and a fifth step of reconnecting the electric pole-side transformer and the low-voltage wires and opening the breaker of the inspection circuit breaker when the main work is completed. Accordingly, the present invention allows uninterrupted power distribution construction for low-voltage lines to be performed more efficiently and safely. 본 발명은 저압선로 무정전 배전공사 공법에 관한 것으로, 저압선로 무정전 배전공사를 실시하기 위하여, 분기장치 및 검상차단장치를 미리 지정된 위치에 설치하는 제1 단계; 이동용변압기차의 변압기와 이 변압기에 접속하는 분기장치 간에 리드선을 연결하고, 상기 분기장치와 검상차단장치 간에 저압 케이블을 연결하는 제2 단계; 상기 리드선 연결 및 저압 케이블의 연결이 완료되면, 검상 실시 후 검상차단장치의 차단기를 투입하는 제3 단계; 상기 검상차단장치의 차단기가 투입되면, 전주측 변압기와 저압전선을 분리하고, 변압기 교체 및 전선 교체를 포함한 저압선로 무정전 배전공사의 본작업을 실시하는 제4 단계; 및 상기 본작업이 완료되면, 상기 전주측 변압기와 저압전선을 다시 연결하고, 상기 검상차단장치의 차단기를 개방하는 제5 단계;를 포함한다.
