With the improvement of economy and the rising of power demand, the power grid is rapidly developed, the number of transformer substations is increased day by day, the scale of power facilities is continuously enlarged, and the maintenance, comprehensive transformation and reconstruction and extension work of equipment in the transformer substations are more and more. With more and more foreign work projects in power enterprises in recent years, the use of foreign labor is increasing. Due to the particularity of the external wrapping engineering, the complexity of the transformer substation, variable operating environment, uneven personnel quality and construction progress, and the influence of various factors, some external workers have low safety awareness and insufficient control on regulations and systems, and the situations of untight closing, incomplete safety compromise and incomplete field safety supervision and management exist. Furthermore, some external workers are under brute force to freely override, move or remove safety measures deployed by the operators, and operate under the condition of losing supervision, and the operators cannot always supervise on the working site, so that the safety management difficulty is high. Therefore, how to improve the safety level of a transformer substation working site, prevent and eliminate accidents and ensure the safe production of the transformer substation is a very serious problem.

In order to effectively control risks and facilitate daily work of operation and maintenance personnel, safety measure deployment workload is reduced, and a hierarchical management mode is adopted for risk management of secondary equipment of a transformer substation. The hierarchical management is because the secondary devices are generally installed in the cabinet, and if the cabinet is not opened to the outside, the secondary devices in the cabinet are all in a safe state. When the screen cabinet door is opened, and the internal secondary equipment has potential safety hazards in an individual state, the secondary equipment such as a terminal, an overhaul line, a secondary pressing plate and an air switch need to be managed respectively. Therefore, the mode of overall management of the screen cabinet is called group-level management, the mode of respectively managing the secondary equipment when the screen cabinet is opened is called individual management, and the individual management of the secondary equipment is required to improve the field safety level only when the screen cabinet door is in an opened state during maintenance, so that the electric power screen cabinet lock integrating the sign and the lock can effectively solve the problems.
