Failure indication device of sealing-tape machine protecting equipment

The utility model belongs to the technical field of electrical failure detecting equipment and discloses a failure indication device of sealing-tape machine protecting equipment. The failure indication device of the sealing-tape machine protecting equipment is used for failure monitoring of the sealing-tape machine protecting equipment. The failure indication device of the sealing-tape machine protecting equipment comprises a voltage sensor, an address encoder and a main machine, wherein the voltage sensor is connected to the two ends of the sealing-tape machine protecting equipment in parallel, the output end of the voltage sensor is connected with the input end of the address encoder, and the output end of the address encoder is connected with the main machine. According to the failure indication device of the sealing-tape machine protecting equipment, the voltage across the sealing-tape machine protecting equipment is monitored in real time to judge whether a failure exists, and then heavy work of one-by-one manual troubleshooting is avoided.
