The recently released "Opinions on Promoting the Construction of New Urban Infrastructure and Building Resilient Cities" emphasizes the importance of improving the resilience of urban facilities, management resilience and spatial resilience to promote the safe development of cities. Against this backdrop, the municipal industry is welcoming new development opportunities, but is also facing challenges such as cost and environmental pressures brought about by the increase in project scale, as well as harsh construction environments. Enterprises urgently need to rely on more reliable, efficient and green industrial automation equipment to continuously improve project quality and resilience while ensuring facility safety, thereby achieving energy conservation, cost reduction, and quality and efficiency improvements.
As an electric energy control device that drives and controls large equipment, medium-voltage inverters achieve energy saving and efficiency improvement by adjusting the motor speed. They are mainly used in water supply, drainage, heating and ventilation systems in municipal engineering. Aiming at the three major application scenarios of municipal heating, water supply and drainage, and waste-to-energy in cities, Schneider Electric's newly developed Altivar 1200C-S medium-voltage inverter can Significantly improve the automation level and reliability of municipal engineering systems. This not only helps enterprises achieve energy conservation and emission reduction and reduce equipment operation and maintenance costs, but also provides strong support for the high-quality construction of cities.
In the field of municipal heating, as the construction of long-distance heating projects accelerates, companies are paying more and more attention to overall cost control, service guarantees throughout the product life cycle, and factory delivery capabilities. Schneider Electric's ATV1200C-S medium voltage inverter uses a new generation of power electronic devices and innovative structural design, which can save 25% to 50% of the floor space of the whole machine, helping enterprises improve space utilization and avoid additional plant investment, thereby optimizing the total Cost of ownership. In addition, based on real user needs, Schneider Electric can provide full life cycle services from project demand research, solution planning, design deployment, installation and commissioning to spare parts, repairs, maintenance, training, transformation and replacement. It is worth mentioning that its service team has obtained ISO9001 certification, the average on-site service years of its engineers are more than 15 years, and their rich maintenance experience and nationwide after-sales service network can quickly respond to the service needs of enterprises in various places.
In the field of water supply and drainage, from centralized sewage treatment plants to pumping stations for large-scale water diversion projects, users have different requirements for the power, number, configuration, and heat dissipation methods of medium-voltage inverters. At the same time, the chlorine content in the air in the application environment of urban water plants is relatively high, which also puts higher requirements on the environmental adaptability of the equipment. ATV1200C-S medium voltage inverter provides customized voltage level products, covering capacities from 200kVA to 20000kVA. Combined with Schneider Electric's full life cycle services, it can meet the customized application needs of different companies in different scenarios. Especially in wastewater treatment, the ATV1200C-S medium voltage inverter achieves higher power savings by improving process reliability. At the same time, the ATV1200C-S medium voltage inverter adopts solid-sealed cast voltage detection devices, ceramic/epoxy packaged bypass contactors, and built-in environmental monitoring and automatic adjustment functions, which not only enhances its own insulation strength and environmental adaptability, but also Real-time monitoring of temperature and humidity data in the cabinet and equipment operating status, automatic start and stop of heaters, improved operating environment, reduced equipment failure rate, and ensured continuity and stability of water supply and drainage.
In the field of waste-to-energy, medium-voltage inverters are mostly used for various types of fan loads in power stations. It is necessary to adjust the speed of various types of fans according to changes in waste consumption in order to flexibly adjust the power of the unit and achieve energy saving and consumption reduction. Due to the continuous output of urban garbage, higher requirements are placed on the reliability of equipment. With reliable upgrades of all elements, the power unit of the ATV1200C-S medium voltage inverter adopts long-life metal film capacitors, which significantly reduces the risk of capacitor failure and extends the capacitor life to approximately 15 years. In particular, the power units of 80A and below adopt integrated IGBT module packaging technology. The "rectification + inverter" structure further improves the integration of components and the stability of circuit operation. Relying on the highly integrated PCBA design, the integration of devices and the operating stability of circuits are improved. In addition, the ATV1200C-S medium voltage inverter supports configuration of power unit bypass, system bypass, high and low voltage ride-through functions, dual-machine hot standby solutions, etc., which can effectively improve equipment availability and reduce unplanned downtime losses.
At present, with the support of Schneider Electric's ATV1200C-S medium-voltage inverter, a municipal heating project in Hebei has achieved automatic speed regulation of water pumps, effectively reducing energy consumption and saving costs. Since urban heating is mainly concentrated in the cold winter, the company used to need to adjust the speed of the motor according to the temperature changes during the day and night to adjust the water supply and water pressure and ensure that the pressure of the main pipes of the water pumps running in parallel is consistent. The use of the ATV1200C-S medium-voltage inverter to perform closed-loop speed control on the motor not only solves the problem of flexible adjustment of water supply, but also maintains a constant water pressure in the main pipe, significantly reducing equipment energy consumption and operating costs. At the same time, the soft start function of the ATV1200C-S medium voltage inverter further reduces the impact on the motor and water pump, effectively extending the service life of the equipment.
Looking forward to the construction of resilient cities in the future, Schneider Electric will continue to use innovation as a driving force to bring more high-end, intelligent, and green industrial automation products to enterprises, meet the diverse needs of municipal engineering in different scenarios, and help create a better and A livable modern city.
