The invention discloses a bracelet and a lock for preventing misoperation of power distribution operation. The bracelet and the lock for preventing the misoperation of the power distribution operationis composed of a background management end, the bracelet and an intelligent lock. The bracelet comprises a body, a wrist strap and an intelligent key; the intelligent lock comprises a lock control module, an unlocking module and a key jack; no power supply is arranged inside the intelligent lock, a serial number of the intelligent lock is arranged in the lock control module, when the intelligentkey is inserted into the intelligent lock, the contact electrode of the intelligent key is in contact with the contact electrode of the key jack, so that a first ring of the key jack becomes a power supply end, a four ring becomes a grounding end, so that the power supply of the intelligent lock is realized; and the intelligent lock is in contact with the intelligent key through a second ring anda third ring of the key jack, and therefore communication between the intelligent lock and the bracelet is realized. The invention aims to provide the bracelet and the lock for preventing the misoperation of the power distribution operation, so that standard operation behaviors of the power distribution operation personnel can be assisted, the electrification interval can be prevented from mistaking, and risks can be reduced.
