The anti-misoperation interlocking devices for distribution network equipment are not fully developed. While mechanical interlocks can prevent misoperations within the same unit, there are still blind spots in preventing misoperations, such as entering the wrong bay or operating equipment on the line side.
The distribution network has many operational scenarios and open environments. On-site operations mainly rely on manual management and daily safety training, lacking technical safety measures.
Many distribution network O&M tasks are carried out by external contractors with inadequate safety awareness, who rely on experience, which poses risks of habitual violations.
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.

Mandatory voltage detection
Mandatory voltage detection is added before operating devices such as grounding switches and network gates to prevent misoperation.
Standardized operations
The system links operation tickets with locks, unlocking keys, and other anti-error devices, standardizing the work process and enhancing operational safety.
High practicality
The system quickly proves effective, solving issues such as "closing grounding switches under live conditions" and "energizing with grounding" through mandatory voltage detection interlock mechanisms.
Easy installation
The high-voltage live display lockout device, equipped with anti-error interfaces, uses standard interfaces, allowing installation and replacement without the need for a power outage.
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.
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.
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.
