The lock forced operation personnel can correctly operate the electrical equipment according to the established safe operation program, thereby avoiding the occurrence of misoperation accidents and fully meeting the five-prevention requirement: (1) prevent the wrong opening and closing of the circuit breaker. The circuit breaker is prevented from being separated and combined by mistake, and the operated equipment can be operated only if the operation instruction corresponds to the operated equipment; (2) preventing the on-load disconnecting switch from being closed. The on-load separating and closing isolating switch is prevented, and the isolating switch cannot be operated in the switching-on state of the circuit breaker, the load switch and the contactor; (3) The grounding wire (grounding switch) is prevented from being hung (closed) by electricity, namely, the grounding wire (grounding switch) is prevented from being hung or the grounding switch is closed only when the breaker (isolating switch) is in a disconnecting state; (4) preventing power transmission with ground wire. Namely, the power transmission with the ground wire is prevented, and the circuit breaker (isolating switch) with the ground wire (grounding switch) is prevented; (5) The compartment can be opened only when the compartment is not electrified.
The five-prevention lock is provided with a padlock and a fixed lockset, and has the function of limiting or not limiting the action states of a switch, a handle and a knife switch of electrical equipment.

(2) The operators cannot be identified on line, and the operators are assigned to operate after unlocking by non-current tasks;
(3) After the operation sequence is downloaded into the five-prevention key, an off-line mode is adopted in each unlocking operation step in the operation, when abnormal conditions are encountered and processed in the operation process, a management blind area is entered, an operation log cannot be formed, and because a data encryption means is not adopted, operation record data is possibly refreshed and tampered, so that in the management, comprehensive and accurate operation records are difficult to obtain, and the operation log cannot be used as key evidence in accident tracing;
(4) The five-prevention mechanical padlock is usually unlocked in a button type mechanical transmission mode, the unlocking time can be recorded in a five-prevention key, but the locking time cannot form a time record, and the problem that the operator is forgotten to close the cabinet door cannot be traced. The mechanical padlock key and the electric lock key can be configured independently sometimes, and the padlock key and the electric five-prevention key are carried during operation, so that the operation management burden is increased.
