The present invention relates to a pole transformer live branch loop safety device, and more particularly, restricts access by separating the live branch ring and the branch sleeve provided in the lower portion of the branch sleeve installed to branch the main power line with a simple structure. This makes it possible to achieve stable electricity supply from the main power line to homes and industries, to prevent safety accidents by exposing the live branch ring only to the lower part, and to provide a ring protection cover that encloses the live branch ring connected to the lower left and right sides. Accordingly, the present invention relates to a pole transformer live branch loop safety device that can be easily separated and inspected.

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.
