[0002] When repairing electrical equipment, it is necessary to disconnect the power to the equipment and ensure effective isolation before carrying out the repair work. While ensuring the isolation of the primary equipment, it is also necessary to disconnect the air switches of the power supply, protection, control, measurement and signal circuits. To prevent the risk of electric shock to personnel from accidentally closing the disconnected air switches, a "Do Not Close, People Working" sign should be hung on the disconnected air switches.

[0003] For large systems, the power supply, protection, control, measurement, and signal circuits are complex. Air circuit breakers are mostly installed side by side and densely, requiring each one to be hung with a sign with a lanyard. Some air circuit breakers are installed with only the operating handle exposed to avoid the risk of electric shock. Since there are no dedicated hanging points, the signs are easy to fall off or obstruct the switch name, affecting the effectiveness of maintenance safety measures and the aesthetics of the maintenance site. Preventing accidental closing of the switch is done solely by hanging warning signs, which poses a high risk of accidental closing. Utility Model Content
