The substation WAPI network has been established to achieve full signal coverage within the station. The wireless intelligent grounding wire management system has been deployed, securely connected to the wireless network, enabling real-time collection of grounding stake status. This transforms the original microcomputer-based anti-misoperation system's "virtual remote signal" for grounding stakes into a "real remote signal," preventing unnecessary operations during grounding wire installation and removal, and eliminating errors such as incorrect attachment or missed removal of grounding wires. An intelligent grounding wire cabinet is deployed to ensure the proper storage of grounding wires and manage their usage based on ticket issuance.
Ground wire coding for ticketing
Unique electronic coding is assigned to ground wires and grounding stakes. During the simulation and pre-enactment on the anti-misoperation master device, the coding is directly entered into the ticket, enabling the designated ground wire to be connected to the specified grounding stake.
Real-time information collection
Internet of Things (IoT) communication technology is utilized to achieve real-time collection of the status and location information throughout the entire process of ground wire usage, installation, removal, and return.
Forced interlock management
The ground wires at the substation are managed through a forced interlock system, ensuring that ground wires of different voltage levels are stored as designated and authorized for use based on tickets, preventing arbitrary placement and removal.
Efficient inventory maintenance
The intelligent grounding wire cabinet's interlock mechanism automatically performs wireless charging for smart grounding wire modules, eliminating the need for manual battery replacement, and reducing maintenance efforts.
Establish a WAPI network in the substation to achieve full signal coverage in the area, and deploy a wireless intelligent grounding wire management system. This ensures safe access to the wireless network and enables real-time data collection of grounding pile status, transforming the original “virtual remote signal” of the grounding pile in the microcomputer anti-misoperation system into a “real remote signal.” This avoids unnecessary travel during grounding wire installation and removal and eliminates the risk of misplacing or failing to remove grounding wires. An intelligent grounding wire cabinet is deployed to ensure the proper storage of grounding wires and manage their usage based on ticket issuance.
Currently, many accidents in transmission and distribution lines are caused by grounding wire issues. While negligence during operation is one factor, the more significant reason is the lack of effective management of grounding wires in transmission and distribution lines. This solution utilizes intelligent monitoring devices installed on grounding wires to enable real-time data collection and uploading of grounding wire connection status and location. Through cloud services and a mobile app, it enables remote monitoring and management of grounding wire storage and usage information. An intelligent grounding wire cabinet is deployed to ensure the proper storage of grounding wires and manage their usage based on ticket issuance.
Substations, power plants, and industrial enterprises store a wide range of safety tools, including insulated gloves, insulated shoes, safety helmets, voltage detectors, and temporary grounding wires. Due to the large number, safety tools are placed in disorder. As a result, a lot of time needs to be spent counting them during inspections. The management practices are outdated . The UT-7710 series intelligent safety tool management system assigns electronic identification to safety tools, enabling online detection and intelligent lifecycle management. The safety tool management device can be used independently or used with other systems to achieve advanced management of safety tool .
The UT-050 series intelligent unlocking key management machine uses electronic sealing technology and mobile internet technology to standardize the authorization of all unlocking keys and automatically store usage records. These technical measures ensure the proper management and use of unlocking tools (keys). It accurately records details such as the applicant, approver, reason for unlocking, key retrieval, and return, and enables key monitoring, remote control, and directional unlocking, eliminating human errors, standardizing the management of unlocking tools (keys), and ensuring the safety of on-site personnel as well as the O&M safety of power grid equipment.
