However, the traditional mechanical cabinet door lock has its shortcomings:
1. The mechanical cabinet door lock’s ability to prevent technical opening is very poor. Regardless of the structure of the mechanical cabinet door lock, it can be opened by other means, and the key can be copied and there is a great security risk.
2. At present, in substations, the cabinet locks and keys provided by the same equipment manufacturer are generally the same. This type of key can be used with all cabinet locks provided by this manufacturer, which invisibly lays hidden dangers for misoperation by operators.
