PARTIAL DISCHARGE ONLINE MONITORING

To meet the evolving requirements of live‑line maintenance for GIS, transformers, switchgear, and cables, this approach leverages IoT and smart sensor technologies to enable continuous monitoring of power equipment under live conditions. By employing intelligent sensing techniques—such as transient earth voltage, ultrasonic, ultra‑high frequency, and temperature measurements—it achieves smart perception of the operational status of transformers, GIS, switchgear, and power cables. Furthermore, through advanced diagnostic algorithms and multi‑dimensional comparative analysis, it enables intelligent interpretation of monitoring data and automated condition assessment, ensuring real‑time awareness of operating conditions and timely identification of potential defects.

INTELLIGENT CONTROL DEVICE

The intelligent operating and display device for switchgear is a multifunctional, intelligent, integrated dynamic indicator designed to meet the current advancements in medium-voltage switchgear technology. It is primarily used in indoor switchgear of voltage ratings ranging from 0.1 to 40.5 kV. The product provides centralized indication of the primary circuit's simulated status, the position of the handcart, the positions of the isolating switches and earthing switches, the switch's on/off status, and the energy‑storage status of the operating mechanism. It also features high‑voltage live‑indication, energized‑lockout output, automatic heating and dehumidification, real-time digital display of temperature and humidity, heater‑fault monitoring, intelligent voice‑based error‑prevention prompts, infrared human‑presence sensing (standard), and an RS‑485 communication interface.
