2. Description of the Related Art In power generation and substations mainly for electric power, which handle a high voltage of several kilovolts or more or an ultra-high voltage of tens of thousands of volts or more, each device or cable is installed once a year or once a few years. It is necessary to perform regular inspections at a certain rate, and to disassemble and repair or replace when an accident occurs. Each of these devices and cables should be placed at a height above the ground or floor where humans will not accidentally raise their hands, for example, at least 250 cm.
It is located in the above high places. This type of power transmission / distribution equipment has multiple lines in case of power failure such as disconnection, short circuit, or lightning strike.
It is possible to distribute electricity. Therefore, a short inspection
In the repair work, instead of causing a power outage of the entire facility, a partial power outage is performed by using the spare circuit of the facility, and while transmitting power, inspection, repair, and replacement work of the equipment are sequentially performed. However, since such work is performed at a high place and a voltage of several kilos to tens of thousands of volts is charged in the adjacent equipment or cable, inspection and repair work can be said to be a very dangerous work environment.

The repair work mainly involves handling heavy objects in high places, but since there are high-voltage charging devices and live-line cables in the vicinity, it is difficult to use large cranes and trolleys that are used during new construction. The contents and tools used vary widely. In general, it is most efficient and accurate for this kind of various work to be performed by human beings in direct contact with the equipment by building scaffolding on site. However, it is still a dangerous work environment, and it is difficult to eliminate electric shock accidents to people and things even if you pay close attention.
