This lock forces the operation personnel to carry out exact operation to electrical equipment according to established safe operation procedure to avoid the emergence of maloperation accident, fully satisfy "five prevent" requirement: (1) and the circuit breaker is prevented from being opened and closed by mistake. The circuit breaker is prevented from being wrongly opened and closed, and the operated equipment can be operated only if the operation instruction corresponds to the operating equipment; (2) prevent the isolating switch from being switched on and off under load. Namely, the isolating switch can not be operated when the breaker, the load switch and the contactor are in a closing state; (3) the grounding wire (grounding switch) is prevented from being hung (closed) in a charged state, namely the grounding wire (grounding switch) is prevented from being hung or closed only in the brake-off state of the circuit breaker (isolating switch); (4) preventing power transmission with ground. Namely, the power transmission with the ground wire is prevented, and the circuit breaker (isolating switch) with the ground wire (grounding switch) is prevented from being closed; (5) prevent the mistake and go into electrified interval, prevent promptly that the mistake from going into electrified interval, only when the compartment is uncharged, could open the door and get into the compartment.
The five-prevention lock has two types of padlock and fixed lockset, and is used for limiting or not limiting the action states of a switch, a handle and a knife switch of electrical equipment.
The inventor finds that the conventional five-prevention lock management method has the following problems:
(1) in the prior art, the character numbering processing is not carried out on the open equipment operation box of the transformer substation and a corresponding padlock, and a user easily makes mistakes when the lock is recovered according to the number after the use is finished, namely, the wrong position of the padlock is easily caused to cause wrong intervals;
(2) the method comprises the following steps that online identification cannot be carried out on operators, and the situation that the operators are not appointed by the current task to operate after unlocking exists;
(3) after the operation sequence is downloaded to the five-prevention key, an off-line mode is adopted in each unlocking operation step in the operation, when an abnormal condition is met and processed in the operation process, the operation enters a management blind area, an operation log cannot be formed, and due to the fact that a data encryption means is not adopted, operation record data are possibly refreshed and tampered, so that comprehensive and accurate operation records are difficult to obtain in the management, and the operation record data cannot be used as key evidences during accident tracing;
(4) the five-prevention mechanical padlock usually adopts a button type mechanical transmission mode to unlock, the unlocking time can be generally recorded in a five-prevention key, but the locking time cannot form a time record, and the problem that the closing of an operation box cabinet door is forgotten cannot be traced. The keys of the mechanical padlock key and the electric lock are sometimes independently configured, and the padlock key and the electric five-prevention key need to be carried during operation, so that the operation management burden is increased.

As shown in fig. 1, 2, 3 and 4, the lock is an electric lock, an active or passive cabinet lock, an active or passive padlock, and each lock has a controller, an encryption chip, a memory and a data interface adapted to an electronic key.
The padlock of this embodiment is encrypted and calculated into a lock verification code according to the execution timestamp, the operator ID, the task number after unlocking or locking, and is stored as the lock block, but does not store the specific execution timestamp, the operator ID, the subtask ID, because the computing power and the memory capacity of the passive lock are limited. For example, the data of the execution timestamp, the operator ID and the task number are 1kb, one lock verification code can be 128b, and the lock verification code of each passive padlock or passive lock is calculated independently, which can be data of the number of selected previous bits after calculation by a specific formula.

The electronic key and the host are physically connected in a plug and socket mode or are in data transmission through an NFC antenna, and due to the fact that development of a wireless signal is not allowed in a transformer substation to access a safety I area, the host is located in the safety I area, and therefore the electronic key is not suitable for setting a wireless transmission mode with the same length as Bluetooth wifi.
As shown in fig. 6, the electric lock is used for generating an excitation signal to the triode after verification after the plug of the electronic key is inserted into the interface, the output interface supplies power to the relay of the control cubicle, and the output interface is powered off after the key is pulled out.
The host is connected with the server through a network cable; the host acquires the state of each electrical device; the server is responsible for collecting various data of a plurality of substations.
The transformer substation camera is responsible for collecting video information in the transformer substation, and not every electrical element ID can have video information, and electrical element and camera are not the one-to-one correspondence, and it is possible that one electrical element has five cameras to see, also can all not see.
For each switching operation step, the operation starting time is the unlocking time, and the operation ending time is the door locking time. For the abnormal handling behavior in the switching operation process, the switching locking time record is used for calibrating the operation behavior track of each interval, so that the accident handling and management tracing are facilitated. When obvious defects such as software program errors and the like occur in the five-prevention system, the computer key has a remote authorization unlocking function, and mechanical and short-circuit unconditional unlocking keys are cancelled.
