Description
technical field [0001] The invention relates to a live warning device for a switch cabinet, which belongs to the field of warning devices. Background technique [0002] An identification plate is hung on the existing switchgear, or a safety fence is placed around the switchgear, so as to prevent equipment maintenance personnel from touching live equipment and causing safety accidents. Due to the large number of switch cabinets in the power supply bureau and the heavy maintenance tasks of equipment maintenance personnel, even experienced equipment maintenance personnel cannot figure out the location of each live device, which means that when the identification plate falls from the switch cabinet, or the safety After the fence is moved artificially, equipment maintenance personnel are likely to have safety accidents during the routine maintenance of the switchgear. Contents of the invention [0003] The problem to be solved by the present invention is to provide a live warn...
