Description

COS Holder Fixing Apparatus {FIXING APPARATUS OF COS HOLDER} The present invention relates to a COS holder mounting device, and more specifically, to a COS holder mounting device capable of preventing a power distribution COS holder from falling to the ground. A COS (Cut Out Switch) is attached to the responsibility demarcation point of an extra-high voltage overhead line and the primary side of a pole-mounted transformer to be used for the protection and switching of the transformer. When COS holders are left at the site after the supply point is turned off—such as during high-voltage customer disconnection, voluntary termination, or requests for disconnection during periodic inspections—there is a risk that the holders may fall to the ground due to typhoons or strong winds, causing safety accidents to nearby buildings and pedestrians. Therefore, there is a need to improve this situation. The background technology of the present invention is disclosed in Korean Registered Patent Publication No. 10-1499652 (Registered on March 2, 2015; Title of Invention: Integrated Installation Structure of Lightning Arrester and Cutout Switch for Protection of Pole-Mounted Transformer). FIG. 1 is a conceptual diagram schematically showing the state in which a COS according to one embodiment of the present invention is mounted on a COS holder. FIG. 2 is a conceptual diagram schematically showing a COS holder mounting device according to one embodiment of the present invention. FIG. 3 is a perspective view schematically showing a holder part and a connecting part in a COS holder mounting device according to one embodiment of the present invention. FIG. 4 is an assembled perspective view schematically showing a holder part and a connecting part in a COS holder mounting device according to one embodiment of the present invention. FIG. 5 is a schematic perspective view showing the connection to the connecting part in a state where the COS is removed from the holder part of a COS holder mounting device according to one embodiment of the present invention. FIG. 6 is a perspective view schematically showing a connecting part in a COS holder mounting device according to one embodiment of the present invention. An embodiment of a COS holder mounting device according to the present invention will be described below with reference to the attached drawings. In this process, the thickness of lines or the size of components shown in the drawings may be exaggerated for clarity and convenience of explanation. Furthermore, the terms described below are defined in consideration of their functions within the present invention, and these may vary depending on the intent or practice of the user or operator. Therefore, the definitions of these terms should be based on the content throughout this specification. FIG. 1 is a conceptual diagram schematically showing a state in which a COS is mounted on a COS holder according to an embodiment of the present invention, FIG. 2 is a conceptual diagram schematically showing a COS holder mounting device according to an embodiment of the present invention, FIG. 3 is a perspective view schematically showing a holder part and a connecting part in a COS holder mounting device according to an embodiment of the present invention, FIG. 4 is an assembled perspective view schematically showing a holder part and a connecting part in a COS holder mounting device according to an embodiment of the present invention, FIG. 5 is a perspective view schematically showing a connection to a connecting part in a state where a COS is removed from a holder part in a COS holder mounting device according to an embodiment of the present invention, and FIG. 6 is a perspective view schematically showing a connecting part in a COS holder mounting device according to an embodiment of the present invention. Referring to FIGS. 1 to 6, a COS holder mounting device according to one embodiment of the present invention may include a rack band portion (100), a holder portion (200), and a connecting portion (300). The rack band portion (100) may be installed to wrap around the outer surface of a utility pole (10). The utility pole (10) may be made of a column used as a support for an AC power distribution line. The utility pole (10) may be formed in a cylindrical shape. Depending on the material, the utility pole (10) may be made of wood, reinforced concrete, steel, etc. A high-voltage or low-voltage power distribution line may be attached to the upper side of the utility pole (10), and a cross member (20) that supports this power distribution line may be installed.
