As the carrier of electrical products, the cabinet in the mechanical structure provides installation, support, connection, protection, decoration and other functions for the protection and measurement and control equipment in the substation station, and is an indispensable part of the cabinet door as a cabinet door lock to protect the safety of equipment and personnel.
However, the traditional mechanical cabinet door lock has its drawbacks:1The ability of mechanical cabinet door locks to resist technical opening is very poor. No matter what kind of structure the mechanical cabinet door lock can be opened by other means, and the key can be copied will also have great safety risks. 2.At present, in the substation, the cabinet lock and key provided by the same equipment manufacturer are generally the same, and this key can cover all the cabinet locks provided by the manufacturer, which virtually lays a hidden danger for the operator to misoperate.
In view of the above defects, the new cabinet lock scheme developed and produced by the company changes the traditional mechanical key management to password and authority management in field applications: effectively enhances the security of substation protection and measurement and control equipment, realizes the effective management of the construction operation of operation and maintenance personnel, improves the demand for internal management of the power system, and ensures the reliable operation of the equipment in the station.
This intelligent passive electronic cabinet lock, the lock itself does not install a power supply, so as to avoid wiring operation, set the power supply on the key, and avoid frequent maintenance problems of the lock. So, how does the cabinet lock achieve safe unlocking?There are two ways to unlock a cabinet lock, one is to make an appointment to authorize unlocking, and the other is to use a mobile phone to authorize unlocking. Appointment authorization unlocking: Employees need to brush the number plate to receive the smart key, at this time the administrator will give the key a certain period of unlocking permission, employees can then open all the cabinet locks within the authority with the key, and the relevant data will be recorded after returning the key, so that it is well documented. Mobile phone authorization unlocking: Employees use the mobile app to initiate a lock opening application, and the administrator will authorize unlocking in the background, and after obtaining the unlocking permission, the passive electronic lock will be turned on to complete the entire unlocking process. The intelligent electronic passive cabinet lock, no matter what kind of way is used to unlock, needs to be authorized by the administrator, otherwise it cannot be unlocked, which is also the advantage of the intelligent cabinet lock. The intelligent passive cabinet lock adopts 16-digit 12-digit encoding, three-layer password and protocol protection, and cannot be cracked at presentIn the case of a lost key, the administrator can delete it in the background, and even if someone else picks up the key, it cannot be unlocked. And it has the effect of waterproof and dustproof, which is completely suitable for outdoor installation applications.
