Abstract
Switchgear equipment (a cubicle) that houses various transformers are installed in a substation room that converts 22.9 KV extra-high voltage to low voltage 380/220V. As electrical safety personnel have to inspect the switchgear equipment on daily, monthly, quarterly, and annual basis, electric shock accidents frequently occur due to exposure to high voltage and high current. To remind workers to work safe, the present invention provides an electrical safety alarm apparatus that, before opening a door, not only displays various safety phrases but also reminds the electrical safety personnel of a voice event to thus prevent electrical disasters in advance, and that is installed (attached) to the front/rear side of a switchgear panel to strongly remind operators to pay attention to safety during inspection and maintenance of extra-high and low voltage boards, power MCC boards, distribution boards, plant control boards, and the like to thus prevent electrical disasters in advance.
