A property limit point is provided internally where the first power line of the KEPCO facility and the second power line of the customer facility are connected, and includes a safety connection part mounted at a height where ground work is possible along the longitudinal direction of the pole, The above safety connection part A body part formed in a box shape having an internal connection space, A door part hinged to one side of the above-mentioned body part and coupled to an opening and closing structure, A locking part provided on one side of the door part and controlling the opening and closing of the door part, and A mounting part provided on one side within the above-mentioned body part for mounting a wire fuse provided on the connection line of the property limit point where the first wire line of the KEPCO facility and the second wire line of the customer facility are connected. Includes, The height at which the above-mentioned safety connection part is installed is set to a range of 1.8m to 2.2m from the ground, allowing for work to be performed, in order to prevent safety accidents and unauthorized manipulation by making it difficult for the general public to approach with bare hands, and at the same time, to prevent falls by enabling workers to safely perform wire fuse replacement and inspection work from the ground using auxiliary equipment such as a two-step ladder without the need for separate manual climbing of utility poles. A low-voltage safety connection device comprising a first wire line of the above-mentioned KEPCO facility, which includes an insulating pipe made of high-strength plastic material that surrounds the outside of an insulating wire and protects the insulating wire, wherein one end of the insulating pipe is connected to a connecting base made of rubber material at the upper side of the body part and inserted into the body part, and the portion where the connecting base is located at the upper side of the body part is a sealing part that is silicone waterproofed.
2. In Paragraph 1, A low-voltage safety connection device in which the interior of the above-mentioned body part is coated with an insulating material.
3. In Paragraph 1, A low-voltage safety connection device in which the portion on the other side of the body part that contacts at least the outer surface of the utility pole is formed in a round shape with a preset curvature.

Description

Low Voltage Safety Contact Device The present invention relates to a low-voltage safety connection device. When power distribution operation room staff handle low-voltage faults, such as replacing wire fuses, manual climbing is unavoidable in locations where vehicle access is difficult. Manual climbing is currently implemented on a limited basis, such as in cases where vehicle access is difficult, and statistics from recent years show that fatal accidents caused by falls account for a high proportion of all casualties. There is a persistent concern regarding safety accidents caused by slipping during manual climbing in adverse weather conditions, such as rain or snow, and the basic principle is to perform work using vehicles whenever possible. Although manual climbing is inevitably carried out on-site with the permission of the site manager, there is a need for technological development to enable safer manual climbing. FIG. 1 is a schematic diagram illustrating a low-voltage safety connection device according to an embodiment of the present invention. FIG. 2 is a schematic diagram illustrating the state in which a low-voltage safety connection device according to an embodiment of the present invention is installed on a utility pole. FIG. 3 is a schematic diagram illustrating the state of operation in which a low-voltage safety connection device according to an embodiment of the present invention is installed on a utility pole. The technical terms used herein are for the reference of specific embodiments only and are not intended to limit the invention. The singular forms used herein include plural forms unless phrases clearly indicate otherwise. The meaning of "comprising" as used in the specification specifies a particular characteristic, area, integer, step, action, element, and/or component, and does not exclude the presence or addition of other particular characteristic, area, integer, step, action, element, component, and/or group. Unless otherwise defined, all terms used herein, including technical and scientific terms, have the same meaning as generally understood by those skilled in the art to which this invention pertains. Terms defined in commonly used dictionaries are further interpreted to have meanings consistent with relevant technical literature and the present disclosure, and are not interpreted in an ideal or highly formal sense unless otherwise defined. For example, the term "applied" described below is interpreted to include both the state in which it is appropriately used and the state prior to appropriate use. Hereinafter, embodiments of the present invention will be described in detail with reference to the attached drawings so that those skilled in the art can easily implement the present invention. However, the present invention may be embodied in various different forms and is not limited to the embodiments described herein. FIG. 1 is a schematic diagram illustrating a low-voltage safety connection device according to an embodiment of the present invention, FIG. 2 is a schematic diagram illustrating a state in which a low-voltage safety connection device according to an embodiment of the present invention is installed on a utility pole, and FIG. 3 is a schematic diagram illustrating a state in which a low-voltage safety connection device according to an embodiment of the present invention is installed on a utility pole. Referring to FIGS. 1 to 3, the low-voltage safety connection device according to an embodiment of the present invention includes a safety connection part (100) which is mounted at a height where ground work is possible along the longitudinal direction of a utility pole (P) and has a property limit point (30) inside which a first power line (10) of a power company facility and a second power line (20) of a customer facility are connected.
