The present invention relates to a grid divert ring safety device for power distribution, and more specifically, to protect the home and industry by wrapping and protecting the live branch ring and the branch sleeve provided in the lower portion of the branch sleeve installed to branch the main power line power supply. Stable power supply can be achieved from the main power line, and the live branch ring can be exposed only to the lower part to prevent safety accidents, and hinged fasteners can be installed on the left and right sides for easier inspection as needed. It relates to a live branch loop safety device for column transformer.

일반적으로, 가정이나 산업체 등에 단상 또는 3상 전력을 공급하기 위해서는 배전선로의 주전력선에서 주상변압기의 분기선을 분기한다. 이 경우 대부분 분기슬리브를 이용하게 되어 있는데, 이와 같은 분기슬리브는 활선분기고리를 이용하여 분기선을 주전력선에서 분기시키도록 되어 있다.In general, in order to supply single-phase or three-phase electric power to homes or industries, the branch line of the column transformer is branched from the main power line of the distribution line. In this case, most of the branch sleeves are used. Such branch sleeves use a live branch ring to branch the branch lines from the main power line.

전주 상부의 주전력선에 결합된 분기슬리브에는 활선분기고리가 결합 설치되고, 상기 활선분기고리와 컷아웃스위치에는 각각 1차리드선이 연결되며, 상기 컷아 웃스위치와 주상변압기에는 각각 2차리드선이 연결되어, 상기 주상변압기로부터 전력이 공급된다.The branch sleeve coupled to the main power line of the electric pole is coupled with a live branch ring, and the live branch ring and the cutout switch are respectively connected with a primary lead wire, and the cut out switch and the column transformer are connected with a secondary lead wire, respectively. Then, electric power is supplied from the columnar transformer.

상기와 같이 전주의 주전력선에는 분기슬리브가 반드시 설치되는바, 상기 분기슬리브는 전력의 공급뿐만 아니라 건축물의 신, 증축 또는 철거 등으로 인하여 주상변압기를 제거하여 전력의 공급을 차단한 상태에서도 고압의 전원이 흐르는 상태로 있게 된다.As described above, a branch sleeve is necessarily installed in the main power line of Jeonju. The branch sleeve is not only supplied with power but also removed from the column transformer due to the expansion, extension, or demolition of the building. The power will flow.

그러나, 이러한 종래의 분기슬리브에 설치된 활선분기고리는 상기 분기슬리브의 외부로 노출되어 있기 때문에 이물질 적층으로 인한 오작동 및 각종 안전사고를 유발하는 문제점이 있었다.However, since the live branch ring installed in the conventional branch sleeve is exposed to the outside of the branch sleeve, there is a problem of causing malfunctions and various safety accidents due to foreign matter stacking.
