Description

Safety-type Underground Line Connection Device with Improved Convenience {Equipment for Underground Line} The present invention relates to a safety-type underground power distribution line connection device with improved convenience. Generally, electricity produced at power plants is distributed to each consumer through overhead distribution lines. Meanwhile, recently, underground power distribution using power conduits is being widely used rather than overhead power distribution for urban aesthetics and safety. As shown in Fig. 1, the underground power distribution method involves installing a tray (2) inside a power conduit (1) to arrange the underground power distribution line (3). However, in the past, when a leakage current occurred from the underground power line (3), it could not be immediately detected, so there was a risk of leakage accidents. In addition, conventionally, when placing an underground power line (3) in a tray (2), it was difficult to safely move the underground power line (3) to the tray (2) and conveniently place the underground power line (3) on the upper surface of the tray (2). FIG. 1 is a drawing for explaining the prior art, and FIG. 2 is a front view for illustrating the present invention, and FIG. 3 is a cross-sectional view along the line X-X' of FIG. 2, and FIG. 4 is a cross-sectional view along the Y-Y' line of FIG. 2, and FIG. 5 is a partially cutaway perspective view illustrating the wire traction part of the present invention, and FIG. 6 is a control configuration diagram of the present invention, and FIGS. 7 to 10 are diagrams illustrating the operation of the present invention. The present invention is described below so that a person skilled in the art can easily practice the present invention.
