UNINTERRUPTIBLE POWER DISTRIBUTION WORK METHOD FOR LOW VOLTAGE LINE

The present invention relates to an uninterruptible power distribution work for a low voltage line. To this end, the uninterruptible power distribution work for a low voltage line comprises: a first step that a branching device and a phase inspection blocking device are installed at a designated location; a second step that a lead line is connected between a transformer of a movable transformer vehicle and the branching device connected to the transformer, and a low voltage cable is connected between the branching device and the phase inspection blocking device; a third step that, when the connection of the lead line and the low voltage cable is complete, phase inspection is performed before a breaker of the phase inspection blocking device is introduced; a fourth step that, when the breaker of the phase inspection blocking device is introduced, the transformer and a low voltage electric line close to an electric pole are separated, before a main work in the uninterruptible power distribution work for a low voltage line is performed, including replacement of the transformer and the electric line; and a fifth step that, when the main work is complete, the transformer and the low voltage electric line close to the electric pole are connected again, before the breaker of the phase inspection blocking device is released. 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.
