Problems solved by technology

[0002] At present, during the maintenance of equipment outside the substation in the power system, the operating equipment adjacent to the equipment that needs to be overhauled is in a charged state. This type of live operating equipment is called a "dangerous point" in the safety production of the power system; Operators mistakenly enter the area, mistakenly log in or touch live equipment and cause personal and equipment accidents, in accordance with the provisions of Clause 7.5. figure 1 As shown, in the working area, at the dangerous point 1 and the dangerous point 2 facing away from the electrified area, the "stop, high voltage danger" signboard is hung to warn the maintenance workers not to enter the electrified area and approach the dangerous point; however, in actual In the process of work, due to factors such as lack of concentration, work fatigue, and carelessness, it is easy for maintenance operators to stray into live areas, approach dangerous points, and cause personal injury accidents by mistakenly boarding or touching live equipment, threatening the safety of maintenance workers. life safety

[0003] Although the "stop, high voltage danger" signboard clearly distinguishes the working area and the live area, this kind of signboard is not easy to attract attention in an environment with many equipment, miscellaneous personnel, and loud maintenance tools and appliances, and is often useless; therefore, for To more effectively warn that the live area is a dangerous point, a LED alarm device for the live area is particularly important
