The present invention relates to a safety device for a live branch ring of a distribution-type column transformer, and more particularly, a charging part by covering the outer edge of the power line and the live branch ring with an insulating cover configured to surround the power wire and the live branch ring regardless of whether the power line is in use or not in operation. By not being exposed to the outside, safety accidents can be prevented in advance when working around power lines, and existing live branch rings that can be reused without being dismantled in the event of changes in power distribution facilities can be used to reduce installation costs as well as distribution work. This invention relates to a safety device for live branch ring of a distribution-type column transformer for faster and safer operation.

일반적으로 가정이나 산업체 등에 단상 또는 3상 전력을 공급하려면 전주에 설치된 전력선으로부터 분기슬리브를 이용하여 활선분기고리를 설치하고, 상기 활선분기고리로부터 1차리드선을 컷아웃스위치에 연결한 다음 컷아웃스위치로 부터 2차리드선을 주상변압기에 연결하여 주상변압기로부터 전력이 공급되도록 하여야 하는바, 상기와 같이 반드시 전주의 전력선에 활선분기고리가 설치되는데 이 활선분기고리는 전력의 공급시는 물론 건축물의 신,증축 또는 철거 등으로 인하여 주상변압기를 철거함으로써 전력의 공급을 끊은 상태에서도 고압의 전원이 가해진 상태로 상존되어 매우 위험한 문제점이 있었다. In general, in order to supply single-phase or three-phase electric power to homes or industries, a live branch ring is installed using a branch sleeve from a power line installed in a pole, and a primary lead wire from the live branch ring is connected to a cutout switch, and then a cutout switch. The secondary lead wire must be connected to the column transformer to supply power from the column transformer. As shown above, a live branch ring is installed on the power line of Jeonju. By demolition of the columnar transformer due to expansion or demolition, there was a very dangerous problem because the high voltage power was maintained even in the state in which the power supply was cut off.

즉, 분기슬리브커버로 덮힌 곳 외에는 활선분기고리가 그대로 외부에 노출되어 있어서 전력선 가까이에서 이삿짐 센터용 사다리차나 건설용 현장 펌프카 등의 접촉, 그리고 한전의 버켓 트럭의 접촉은 물론 그 밖에 바람에 날리는 연, 은박지, 녹음테이프, 나뭇가지, 나뭇잎과 까치 등 조류 등의 접촉사고로 안전사고 및 선로고장이 발생할 위험성이 항상 존재하게 되는 문제점 있었다.
In other words, the live branch ring is exposed to the outside except the branch sleeve cover, so that the contact of the moving center ladder truck, construction site pump car, etc., the contact of the bucket truck of KEPCO, as well as the wind blowing near the power line There was a problem that there is always a risk of safety accidents and track failures due to contact accidents such as birds, tinfoil, green tape, tree branches, leaves and magpies.
