Safe-use monitoring device for power fuse

The invention discloses a safe-use monitoring device for a power fuse. The safe-use monitoring device comprises a resistor and a capacitor, wherein the input terminal live wire of the fuse is connected in series with the capacitor and the resistor through a head-end diode and a head-end display lamp; the other end of the resistor is connected with a neutral wire; the output terminal live wire of the fuse is connected in series with the capacitor and the resistor through a tail-end diode and a tail-end display lamp; and the head-end display lamp and the tail-end display are both LEDs. The safe-use monitoring device can visually display whether the fuse is fused or not; and when follow-up equipment is powered off, a maintenance personnel can promptly judge whether the fuse is fused or the follow-up equipment goes wrong, so that the maintenance personnel can immediately take effective maintenance measures and the working efficiency is improved accordingly.
