Description

Electric shock accident prevention system with transformer and distribution line}

The present invention relates to an electric shock prevention system for electric poles equipped with transformers and distribution lines in the field of power distribution technology. More specifically, a ring bearing is installed on an electric pole and a rotating housing with an insulating glove inside is fastened to the ring bearing to rotate. By doing so, the worker arranges the rotating housing according to the working position and wears insulating gloves before working to prevent electric shock due to electric leakage. By detecting electric leakage when it occurs and sending a detection signal to the outside, it prevents electric shock accidents from occurring again. It is about an electric shock prevention system on electric poles equipped with transformers and distribution lines that prevents and allows prompt maintenance.

In general, overhead distribution lines are made by fixing complete steel at a relatively high position at the top of utility poles installed at regular intervals on the roadside, and supporting the overhead distribution lines to which relatively high voltage is supplied in an insulated state through insulators installed on the complete iron, and supporting them at high locations. It is common to fix a low-voltage complete iron to the lower part of the complete iron installed, and to support the low-voltage overhead distribution line in an insulated state through an insulator installed on the low-voltage complete iron.

High-voltage electricity is distributed at high voltage through the overhead distribution line by installing a pole-mounted transformer between the pole-iron pole and the low-voltage pole-iron at a relatively high position, connecting the high voltage to the input terminal of the pole-mounted transformer, and connecting the low-voltage overhead distribution line to the output terminal of the pole-mounted transformer. It is stepped down into low-voltage electricity by a pole-mounted transformer and distributed through low-voltage overhead distribution lines.

In these conventional overhead distribution lines, electric leakage occurs mainly due to defects and failures of pole-mounted transformers, and accidents resulting in electric shock to workers often occur.

However, in the past, there was no device to prevent electric shock on overhead distribution lines or electric poles, so there was a problem that electric shock accidents frequently occurred to workers, and when an electric shock accident occurred, it took a lot of time to recognize it and call an ambulance. The problem of delayed emergency measures always exists.

The above-described invention refers to the background art of the technical field to which the present invention pertains, and does not mean prior art.
