An arm structure of a pole to attach and detach a transformer is provided to improve operation efficiency by minimizing the input of various apparatus for replacing the transformer. An arm structure of a pole to attach and detach a transformer includes a lower fixing band(530), a supporting nail, four frames(300), a lower linker, a pair of fixing bodies(400,400'), an upper linker, a middle fixing band(520), a support(200), an arm brace(100,100'), and an upper fixing band(510,510'). The lower fixing band(530) is fixed to cover an outer circumference of an electric pole, and has a protruded coupling unit(220). The supporter fixes and covers an upper end of the coupling unit(220). The four frames(300) are arranged in parallel to the pole on the supporter, and respectively placed in four directions of the electric pole. The lower linker is arch-shaped, and is connected with an lower end of the frame(300) to fix the frame(300). The pair of fixing bodies(400,400') are arranged on the upper linker to face and cover the electric pole from the inside surrounded by the frames(300). The upper linker connects upper ends of the frames(300). The middle fixing band(520) is fixed to cover the outer circumference of the electric pole, is connected with the upper linker to fix the upper end of the frame(300) and the electric pole. The support(200) is connected with the middle fixing band(520) at an upper end of the coupling unit(220). The arm brace(100,100') is horizontally arranged by being engaged with the support(200). The upper fixing band(510,510') is fixed to cover the outer circumference of the electric pole, is connected with the arm brace(100,100'), and fixes the arm brace(100,100') and the electric pole. |
