Description

Technology Field

[0001] The present invention relates to a device for preventing safety accidents for workers during power distribution line work in the field of power distribution technology. More specifically, it relates to a device for preventing safety accidents for workers during power distribution line work that detects leakage current occurring in a cable of a power distribution line and notifies the leakage current condition, thereby preventing safety accidents from occurring during the process of installing and maintaining the cable, and provides a lift transport unit and a guide protection unit so that the worker can easily move up and down and perform work, and prevents falls during the lifting and moving process and the work process. Background Technology

[0003] Generally, electricity produced at power plants travels along the transmission lines to substations, where it is lowered to a lower voltage and supplied to general buildings and factories via distribution lines. Additionally, a portion of the extra-high voltage supplied to substations is reduced to a usable voltage through pole-mounted transformers and surface transformers attached to utility poles, and then supplied to homes, shops, and small factories.

[0004] The transformers on these utility poles are devices that convert AC power supplied to one winding into AC power of a different voltage to the other winding through electromagnetic induction, and consist of an iron core and insulating materials such as insulating oil that form a single common magnetic circuit with the windings constituting the electrical circuit.

[0005] Cables, which are distribution lines connected to a substation, are connected to the aforementioned utility poles to guide electricity, and the cables, which are distribution lines supported by the utility poles, are connected to multi-unit residential buildings to supply electricity.

[0006] However, conventional cables, which are distribution lines supplying electricity to multi-unit buildings, are fixed to the walls of the multi-unit buildings using brackets. Maintenance is performed when the sheath of the cable is damaged or a short circuit occurs. However, there is a problem in that safety accidents frequently occur because there is no separate means to detect or report short circuits during the installation and maintenance process of the cable. Additionally, there is a persistent problem in that falls frequently occur because workers perform installation and maintenance work while suspended from a separate ladder or rope.

[0007] The aforementioned invention refers to background technology in the technical field to which the present invention belongs, and does not refer to prior art. Prior art literature
