The use of paper records for tracking grounding wire usage is time-consuming and labor-intensive, and poor management often leads to the process becoming mere formality.
The inability to collect connection status leads to serious safety hazards such as incorrect removal, missed removal, incorrect attachment, and missed attachment, posing significant risks to both personnel and equipment safety.
Grounding wire connection points are untraceable, leading to potential hazards such as entering the wrong bay.
The retrieval and usage records of grounding wires lack digital methods, making it impossible to maintain electronic records, which creates challenges for performance evaluation and traceability.
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.
Ground wires retrieved based on tickets
The ground wires are locked using a locking device inside the intelligent ground wire cabinet. Only after the user unlocks the ground wire based on the operation task can the wire be retrieved, and the retrieval record is generated.
Ground wire status awareness
The ground wire detection device automatically detects the ground wire connection status and transmits the data back. Users can view the ground wire status in real time through the system software.
Real-time position tracking
The ground wire detection device automatically detects the ground wire connection status and transmits the data back. Users can view the ground wire status in real time through the system software.
Real-time position tracking
Once the grounding wire head is connected, the current location is obtained via GPS or BeiDou and transmitted in real-time through a wireless network. Users can view the grounding wire location in real-time through the app.
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.
Voltage detection interlocking is a simple and practical intelligent management and control solution proposed according to the requirements of distribution network operation management and control and the characteristics of distribution network equipment. By using high-voltage voltage detection devices with anti-misoperation interfaces in conjunction with grounding switch equipment, the system enforces mandatory voltage detection before operating grounding switch equipment, addressing misoperation issues such as "live grounding disconnector closing," "power-on with grounding," and "entering live dangerous areas" during distribution network equipment operations.
The distribution network operation safety management and control system focuses on risk prevention and control in operational safety, targeting the management and supervision of distribution network O&M and disconnector operations. The system adopts a cloud-based architecture and deployment, relying on the "cloud platform" to achieve real-time online dynamic perception, operation control, and digital mobile operations for the entire process of distribution network on-site work, addressing safety issues during field operations and improving the quality and efficiency of maintenance personnel management.
Based on real-time monitoring data, 3D visualization, and intelligent features supported by AI and IoT technologies, the system comprehensively senses and intelligently controls multi-dimensional information such as equipment, environment, and personnel in distribution substations and transformer areas. It identifies potential faults and abnormal situations, combining human, physical, and technical defenses. It enhances the safety and reliability of distribution substations and transformer areas, reduces manual inspection and maintenance costs, improves response speed, and provides foundational support for the intelligent management of distribution networks.
The distribution network lock control solution addresses the safety management and equipment monitoring needs of box-type substations, branch boxes, ring main units, switch rooms, and other equipment. Based on new IoT and cloud service technologies, it utilizes high-safety keyless locks and digital keys. By binding personnel identities, controlling lock/unlock permissions, and recording operational processes, it enhances the safety of lock operations and ensures traceability and operational safety during maintenance work.
The voltage detection anti-misoperation interlocking solution is developed based on the relevant technical specifications of power grid companies and designed to meet the operational needs of distribution network applications. It addresses key aspects of anti-misoperation interlocking in distribution networks, such as "preventing energization of grounding switches" and "preventing accidental entry into live hazardous areas." The solution provides a simple, practical, and intelligent management and control approach. By integrating a high-voltage voltage detector with anti-misoperation interfaces and grounding switch equipment, it enforces mandatory voltage detection before operations, preventing serious misoperations in the distribution network.
The industrial enterprise power distribution and O&M control system adopts intelligent power technologies such as digital IoT to provide comprehensive monitoring and management of the user-side power distribution equipment, personnel, and environment. It enables operational monitoring, energy efficiency management, intelligent O&M, sub-supply operation, and full lifecycle management of equipment assets. Additionally, it meets the requirements of government and power regulatory authorities for online energy consumption monitoring and demand-side management for energy users.
The distribution network operation safety management and control solution is centered on preventing safety risks during operations, focusing on the management and supervision of O&M tasks and disconnector operations. The system is designed and deployed using a cloud architecture. The cloud-based distribution network operation safety management and control system effectively identifies operational risks. Combined with anti-misoperation interlock devices and real-time graphical display of equipment status, it enables visual, tangible, and controllable management of the entire distribution network operation process, achieving intelligent, mobile, and digital control, thus improving the quality and efficiency of distribution network O&M management.
