XGN15-12 Medium-Voltage Ring Main Unit
The XGN15-12 RMU is an air-insulated, metal-enclosed switchgear assembly designed for power distribution automation. It is compact yet expandable and utilizes SF6 load-break switches, vacuum circuit breakers, or vacuum load-break switches as the main switching elements.
Product Overview
The XGN15-12 RMU is an air-insulated, metal-enclosed switchgear assembly designed for power distribution automation. It is compact yet expandable and utilizes SF6 load-break switches, vacuum circuit breakers, or vacuum load-break switches as the main switching elements.
This series employs standardized components—such as circuit breakers (or vacuum load-break switches), earthing switches, fuse assemblies, instrument transformers, and secondary metering instruments—which can be combined to meet various design specifications. A low-voltage compartment can be added if required. The unit features a reliable mechanical interlocking system that meets the "Five-Prevention" safety requirements.
Performance Features
① Flexible Switch Configuration: The main switch can be selected from SF6 load-break switches, vacuum circuit breakers, or vacuum load-break switches to suit different power application scenarios.
② Compact and Expandable Structure: The unit features an air-insulated design with a compact footprint and supports modular expansion to accommodate power distribution system upgrades.
③ Standardized Component Combination: Uses standardized components that can be configured in various ways to achieve diverse design solutions, offering high flexibility.
④ Reliable Safety Interlocking: Equipped with a reliable mechanical interlocking system that meets "Five-Prevention" requirements (preventing incorrect opening/closing of circuit breakers; preventing opening/closing of disconnectors under load; preventing earthing wire connection while live; preventing closing with earthing wire attached; and preventing accidental entry into live compartments), ensuring operational safety.
