In medium-voltage power distribution systems, the most commonly used ring network cabinets currently include SF6 gas insulated ring network cabinets, solid insulated ring network cabinets and environmentally friendly gas insulated ring network cabinets. However, due to the greenhouse gas emission problem of SF6 and the difficulty of recycling solid insulation materials, the application of SF6 gas insulated ring main unit and solid insulated ring main unit will be limited. With the global promotion of the concept of green and environmentally friendly development, fully insulated environmentally friendly gas ring main units that comply with the latest environmental protection concepts and requirements will usher in historical development opportunities!
IE-EcoAir-15.6/24kV 630A series environmentally friendly switches are a new generation of "fluorine-free and low solid waste" green environmentally friendly circuit breaker switches and environmentally friendly gas insulated ring main units developed to replace traditional SF6 gas insulation.
The environmentally friendly circuit breaker switch adopts an integrated high-strength longitudinal beam, and the vacuum arc extinguishing chamber is wrapped in the longitudinal beam structure. It has the advantages of reliable structure and simple debugging. It isolates the opening, closing and grounding operations of the knife switch by an integrated isolation spindle. Driven by the machine, there is no other arm transmission, the working position is more precise, and the operating force of the isolation mechanism is lighter. The main shaft of the circuit breaker is made of epoxy fiberglass trigger rod, which has high mechanical strength and strong insulation performance. Through the alloy bracket and transmission cam, the opening and closing actions of the vacuum arc extinguishing chamber are realized. The phases are reinforced with silicone umbrella skirts to increase the creepage distance. The environmentally friendly circuit breaker switch is not only suitable for ring main units with sealed air chamber structure, but also for normal pressure metal enclosed ring main units.
Using a solution of environmentally friendly gas insulation and vacuum breaking, the combination of advantages has high overall performance. The primary circuit is gas sealed, the high-pressure components are not affected by altitude, are completely maintenance-free, and have strong environmental adaptability. The cabinet size is small and the layout space requirement is low. Products can be used in power grids, large industries, rail transit, commercial buildings and other usage scenarios.
This product is mainly used in indoor and outdoor ring network switching equipment in 10-24kV medium voltage distribution network systems to receive and distribute electric energy. It is suitable for top expansion, side expansion, and common box (maximum three units) ring network cabinet solutions. The parts common rate of the upper and lower isolation solutions reaches more than 90%. The product has high stability and strong versatility, and fully meets the type test requirements.
Dry compressed air is used as the insulating gas, which has high ionization field strength and breakdown field strength. Direct atmospheric discharge causes zero air pollution. No toxic decomposition substances. Reusable thermoplastic construction avoids greenhouse gas emissions.
Features a highly compact switch cabinet design. The width of the typical 15.6kV solution is only about 400mm, requiring low layout space with reliable wall installation and an operating channel of just 1m in front.
Equipped with a long-life, maintenance-free vacuum arc extinguisher. High-voltage components are fully protected from external elements. Eliminates the need for SF6 gas monitoring systems or leak alarms on site.
Ready to integrate with various secondary equipment to realize online monitoring, remote control, and system protection, meeting the dynamic requirements of modern intelligent distribution networks.
Supports side and top expansion methodologies, making extensions flexible and convenient. Fully compliant with standardization policies and customized power grid configurations.
Designed with split-phase insulation to prevent phase-to-phase short circuits. The non-SF6 gas setup removes breaking failure risks due to gas leaks, incorporating a complete five-prevention interlocking mechanism.
IE-EcoAir-15.6/24kV 630A is designed to operate and serve under normal indoor conditions complying with IEC 62271-1 and GB3906 standards.
This product should be installed on the embedded channel steel on a concrete platform, and the platform base should be robust enough to support the total weight of the equipment.
Note: The foundation channel steel for secondary pouring must be level, and the unevenness per meter should not exceed 1mm. The switch cabinet is fixed on the foundation channel steel and the basic load of the welded switch cabinet is allowed to be 500-700kg/unit.
The height of the switch cabinet is 1650mm (without independent instrument room). If independent instruments are required, the overall switch height is 2000mm. The standard configuration cabinet depth is 850mm.
All components inside the 15.6kV/630A unit are maintenance-free during the declared product life. The isolation and grounding positions can be easily observed to ensure operator safety during cable construction.
The system loop is completely isolated from the atmosphere, and a special arc pressure relief channel is integrated into the air box to protect operators and machinery. Movable parts outside the air box have undergone extensive anti-corrosion treatments and are pre-lubricated. Under extreme environments (dust, sand, and dirt), standard inspections, maintenance, and occasionally part replacements may be recommended.
