HXGN-12 AC Metal-Enclosed Ring Network Switchgear The HXGN-12 AC metal-enclosed ring network switchgear is a compact, highly reliable, and maintenance-free solution designed for medium-voltage power distribution systems. It is widely used in ring main units (RMUs) to ensure efficient power supply, protection, and control in urban grids, industrial plants, and commercial facilities. The switchgear operates at a rated voltage of 12 kV and is suitable for alternating current (AC) systems with a frequency of 50 Hz or 60 Hz. Design and Construction The HXGN-12 features a modular, metal-enclosed design that ensures robust mechanical strength and excellent protection against environmental factors. The enclosure is typically constructed from high-quality steel or stainless steel, providing resistance to corrosion and mechanical impact. The compact structure allows for space-saving installation, making it ideal for applications where footprint is a critical consideration. The switchgear incorporates vacuum circuit breakers or load break switches combined with high-voltage fuses, ensuring reliable interruption of fault currents and overload protection. The vacuum interrupter technology minimizes arcing, enhances operational safety, and extends the service life of the equipment. Key Features and Advantages 1. Safety and Reliability: The fully enclosed design prevents accidental contact with live parts, while the interlocks and grounding mechanisms ensure safe operation. The switchgear complies with international standards such as IEC 62271 and GB 3906. 2. Flexible Configuration: It supports various configurations, including two-way, four-way, or six-way feeder units, allowing customization based on network requirements. 3. Maintenance-Free Operation: The sealed design and vacuum interrupters eliminate the need for frequent maintenance, reducing operational costs. 4. Smart Integration: Modern versions may include intelligent monitoring and remote control capabilities, enabling real-time data collection, fault detection, and automated switching. 5.
