Smart Grounding Box

Using the grounding box as a gateway, and by integrating sensing technologies such as high-voltage cable operating temperature, grounding current, partial discharge, fault traveling waves, and mechanical vibration, it retains the original grounding functionality of traditional grounding boxes while also incorporating a range of online monitoring capabilities. For example, it can continuously monitor parameters like grounding loop current, induced voltage, operating current, partial discharge, cable surface temperature, and the environmental conditions within the cable trench, thereby helping to assess the operational status of the cable line. Each monitored parameter supports upper‑ and lower‑limit alarms. In addition, the system provides functions such as open‑box detection, vibration and tilt alarms, and alarm‑triggered photo capture.

Integrated Grounding Box

Building on the intelligent grounding box's capability to monitor sheath circulating currents, the system now also captures data on the high‑voltage cable core's load current, the three‑phase circulating currents and induced voltages in the grounding conductors, as well as partial discharge at cable joints, environmental conditions, and protection against external damage. Using advanced data‑modeling algorithms, it generates operational status reports, condition‑prediction reports, and anomaly‑analysis reports for the cables. The newly upgraded terminal adopts a modular, configurable design that enables automatic function matching and rapid deployment; it features electrical isolation between the high‑voltage and low‑voltage sections and organizes the equipment layout into three primary work zones: data monitoring, low‑voltage equipment, and high‑voltage equipment.

Smart Inspection System for New Energy Power Plants

The smart inspection system for new‑energy power stations is a novel inspection approach developed to meet the needs of unmanned and intelligent power‑station operations. This platform is suitable for unmanned operation at mountain‑top photovoltaic plants, floating‑roof photovoltaic plants, rooftop solar installations, wind farms, and other types of renewable‑energy generation facilities. Compared with traditional photovoltaic plants, unmanned PV stations offer numerous advantages: lower costs, as automated equipment can handle key maintenance tasks, significantly reducing labor and upkeep expenses; and higher efficiency, with automated cleaning and monitoring ensuring greater operational performance and stability.
