Recently, the first phase of the Shanghai Rail Transit Line 18 from Hangtou to Yuqiao section was completed, and the No. 18004 train was officially launched to complete the first "hot sliding" experiment of the train. DURING THIS PERIOD, EATON, A GLOBAL POWER MANAGEMENT COMPANY, SUCCESSFULLY DELIVERED THE POWER XPERT DX® LOW-VOLTAGE SWITCHGEAR SUPPLYED.
In Eaton's view, the Shanghai Metro project has always been known for its high standards and strict requirements for technology and products, and only technologies and products that have reached the advanced level can be applied to the construction of the project. Eaton's innovative, forward-thinking technology and value proposition, as well as its precise grasp of Shanghai Metro's needs and professional and meticulous service, are the solid foundation for this partnership.
Eaton is powering Shanghai Rail Transit Line 18
Shanghai Rail Transit Line 18, as an important supplement to transfer, is regarded as the main artery of Shanghai's north-south rail transit, using fully autonomous driving technology, including automatic train operation, automatic door opening and closing, automatic turnback, automatic warehousing, self-diagnosis and maintenance, etc., with the blessing of multiple detection systems and a higher safety factor. As a critical infrastructure, safe and stable power distribution equipment and good power quality can provide strong power for trains that shuttle between underground and aboveground spaces day and night.
On this subway line full of science and technology and difficult construction technology, Eaton's POWER XPERT DX® low-voltage switchgear will be used in 37 stations of Shanghai Rail Transit Line 18 due to its durability, stability, operation safety and environmental impact, mainly responsible for the transmission, distribution, power conversion of subway electromechanical equipment, as well as the centralized control and distribution of electric energy, escorting the long-term continuous and stable operation of the station power system. At present, the delivery of 8 stations of the first phase of the project from Hangtou Station to Yuqiao Station has been completed, and the installation and commissioning have been assisted.
POWER XPERT DX® is a low-voltage switchgear equipment launched by Eaton that meets IEC/GB standards, with a current range of up to 6300A, mainly composed of bus area, cable connection area and equipment area, which can be matched with Eaton's full range of high-quality low-voltage components. Its standard fully insulated distribution busbar design is maintenance-free while ensuring safety; The cabinet adopts a modular design, compact structure, and takes up less space, which is very easy to upgrade, expand and follow-up maintenance. In addition, the POWER XPERT DX® low-voltage switchgear has unique safety features, including an arc fault protection system and an autonomous mechanical interlocking function, to ensure the safety of operators and reduce the potential risk of personal safety hazards and equipment damage. Combining safe and reliable operation, ease of operation and maintenance, compact and effective configuration options, combined with Eaton's expertise in low-voltage applications, make POWER XPERT DX® the heart of power distribution applications, further ensuring safe train operation, improving operational efficiency and reducing system operation and maintenance costs.
Race against the deadline and overcome difficulties to catch up with the schedule
As the global epidemic becomes more and more serious, China has bucked the trend and blazed a bright path. In the application of the first phase of Shanghai Rail Transit Line 18, from delivery to equipment installation, many front-line staff of Eaton Power Equipment Co., Ltd. (Changzhou Factory) are not afraid of difficulties to fight on the front line of the project, go against the grain, and strive to provide high-quality products and professional services for the early opening of the station, which once again demonstrates the strength and responsibility of power because of us.
Eaton Power Equipment Co., Ltd. (Changzhou Factory) is a wholly-owned subsidiary of Eaton in United States, covering an area of 30,000 square meters, is the core manufacturing base of Eaton's medium and low voltage complete equipment in the Asia-Pacific region, committed to providing high-quality products, sustainable solutions and customized services at home and abroad, widely used in electric power, metallurgy, chemical, petroleum, mining, real estate and other industries, to help customers manage power more safely, efficiently and reliably.
Faced with challenges such as tight deadlines and heavy tasks, Eaton organized a dedicated service team to respond to the delivery sequence that was temporarily adjusted due to the progress of the project, usually working overtime within two or three days to complete the factory and inspection of more than 20 low-voltage switchgear at one site. At the same time, in the later product installation process, the engineer tracks and guides the whole process and cooperates to solve various problems in the installation process to ensure the on-site construction progress. In particular, in the early stage of power transmission, Eaton arranged a 21-person service commando team with full-time safety officers to complete the installation and wiring of 800 fire alarm devices in five days, helping customers to have power transmission conditions at the scheduled time, which was highly praised.
The unity of knowledge and action, the persistence of professionalism and innovation
Shanghai Rail Transit Line 18 runs an unattended fully autonomous train, and Eaton undertook the debugging of the PLC system, sending the operating status data and power parameter data of each distribution circuit to the central control room, and executing the encoded control instructions sent by the central control room to achieve long-term, safe and stable operation goals. To this end, Eaton urgently set up a key project working group to quickly respond to customer needs, provide professional solutions and customized services, and successfully complete on-site commissioning and power transmission work.
Eaton's expertise and strength in supporting Shanghai Rail Transit Line 18 to build a fully automated rail transit project is another successful practice in the rail transit industry. With the in-depth application of new technologies such as "cloud computing, big data, and Internet of Things" in the field of rail transit, informatization, digitalization, and intelligence have become an inevitable trend in the development of rail transit. With advanced concepts, technologies and deep experience in the rail transit industry, Eaton will continue to innovate digital capabilities, accelerate the integration of products and IoT technologies, and provide more innovative products and solutions for the intelligent upgrade of urban subways to help smart transportation.
