Background
The statements in this section merely provide background information related to the present disclosure and may not necessarily constitute prior art.
The five-prevention lock is a lock for high-voltage switchgear, such as a 10kv high-voltage switchgear. 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.
