The invention provides a five-prevention lock, a five-prevention lock system and a control method thereof. The five-prevention lock comprises a lock body with a lock ring, two-dimensional codes on thesurface of the lock body, an electromagnetic mechanism arranged in the lock body, a communication module in the lock body and used for receiving unlocking or locking commands, a control module arranged in the lock body, and an external connection power interface. The two-dimensional codes include information used for identifying the five-prevention lock and equipment where the lock is located, amagnetic buckle of the electromagnetic mechanism is controlled by electromagnetic force to be matched with the lock ring to achieve locking or unlocking of the five-prevention lock, when the communication module receives the unlocking or locking command, the electromagnetic mechanism is controlled to be powered on and excited to generate electromagnetic force, and the lock buckle and the lock ringare released, and the external connection power interface is used for connection in of the external connection power supply to supply power to the communication module, the control module and the electromagnetic mechanism, the five-prevention lock is identified through the two-dimensional codes, reliable unlocking of the five-prevention lock can be ensured, equipment operation step correctness isensured, safety of power system one-time equipment and remote unlocking can be ensured, and production efficiency is improved.
Description
technical field [0001] The invention relates to the technical field of power system automation, in particular to a five-proof lock, a five-proof lock system and a control method thereof. Background technique [0002] The five-proof lock is a lock for high-voltage switchgear, and the five-proofs specifically include: 1. Preventing the switch from being accidentally pulled and closed; 2. Preventing the isolation switch from being pulled and closed under load; Hang the ground wire; 5. Prevent the switch with the ground wire (ground knife switch) from closing. [0003] When the operator operates the five-proof lock, he needs to operate the electrical equipment correctly in accordance with the established safety operation procedures to avoid misoperation accidents. The existing operation method is that the operator physically connects each five-proof lock with a dedicated terminal on site, and the dedicated terminal reads the information of the five-proof lock to determine wheth...
