MUMBAI, India, Sept. 14 -- Intellectual Property India has published a patent application (202511020635 A) filed by Schneider Electric India Private Limited on March 07, 2025, for Apparatus For Monitoring Fuse Status In Vacuum Contactor Unit.
Inventors include Shirsat, Srushti Sunil; Dash, Sudhansu Sekhar; and Sahoo, Gyana Ranjan.
The application for the patent was published on September 11, 2026, under issue no. 37/2026.
Abstract: The present invention relates to an advanced vacuum contactor unit for air insulated switchgear, featuring a novel fuse blown mechanism integrated with a proximity capacitive sensor. This system enhances fault detection and operational reliability by providing real-time monitoring and immediate response to fault conditions. The non-metallic operating flap, displaced upon fuse blowing, is detected by the sensor, which generates a signal processed by an operating limit switch and a control system. This setup triggers safety measures, such as alarms and safety interlocks, preventing system restart until resolution. The invention supports integration with smart control systems, enabling remote monitoring and predictive maintenance. Key advantages include non-contact sensing, reduced wear and tear, and cost efficiency. The system aligns with Industry 4.0 initiatives, enhancing safety, reliability, and efficiency in power transmission systems. This innovative approach reduces downtime and operational costs, offering a comprehensive solution for modern electrical infrastructure.
