Product Presentation
The primary applications of the intelligent drop-out fuse include mining and oil fields, rural grid upgrades, agricultural irrigation, new energy vehicle charging stations, railway and highway systems, telecommunication base stations, and other 12/24kV terminal distribution substations.
It integrates intelligent current monitoring, switching status indication, temperature detection, short-circuit alarm functions, and wireless data transmission capabilities.
Product Feature
-
Advanced Intelligence
The system integrates multiple sensors to continuously monitor key parameters such as contact temperature, current, and switch position from primary equipment. All data is transmitted in real-time to the master station, enabling remote status monitoring without on-site inspections. This significantly reduces routine maintenance workload. The system also automatically alerts operators upon detecting any abnormal data for prompt troubleshooting.
-
Security Assurance
High-voltage switching operations can be performed remotely, eliminating the need for climbing or working at height. This ensures operators maintain a safe distance from high-voltage equipment, guaranteeing personal safety.
-
Superior reliability
It is immune to operator skill level and prevents misuse, while also meeting all-weather operational requirements unaffected by wind, rain, fog, or darkness.
