This product supports 2500A ultra high power. How to select the core distribution scenario for super large industrial bases?
The selection of core distribution scenarios for super large industrial bases depends on load capacity and production needs. Firstly, for auxiliary distribution in large industrial bases with a load capacity of less than 1600A, the 1600A version is chosen for higher cost-effectiveness and can meet the load requirements of auxiliary distribution; The second is the main power distribution and load capacity of large-scale industrial bases, with a capacity of 1600A~2000A (such as auxiliary workshops in large metallurgical plants and supporting power distribution in petrochemical plants). The 2000A version is selected, which can bear moderate extreme loads and adapt to the main power distribution needs; The third is the core power distribution of super large industrial bases, with a load capacity of 2000A~2500A (such as steelmaking workshops in super large metallurgical plants, core workshops in heavy machinery plants, and reactor clusters in large petrochemical plants). Choosing the 2500A version can bear extremely high loads, ensuring continuous and stable power supply for core production equipment and avoiding large-scale production interruptions caused by load overload. At the same time, multiple equipment collaborative linkage modules need to be matched to achieve load coordination and allocation.
What special equipment is required for the product to adapt to 30km~40km high-power long-distance power distribution?
30km~40km ultra high power long-distance distribution requires three types of special equipment: first, line loss monitoring equipment, using high-precision line loss monitoring modules to monitor the power loss during transmission in real time, optimize the transmission plan in a timely manner, and ensure that the loss is controlled within a reasonable range; Secondly, high-end supporting protection equipment should be equipped with fuses and lightning arresters that are compatible with a voltage level of 24KV. The rated current and short-time withstand current should be matched with a super high power of 2500A. It is recommended to use top-level intelligent protection equipment to achieve intelligent linkage and fault handling with the product; The third is communication and linkage equipment, equipped with high-end communication modules to ensure seamless linkage between the product and the distribution network IoT platform and remote distribution network terminal equipment, realizing remote control, data acquisition, and rapid fault location. At the same time, it can be matched with power quality optimization equipment to improve the power quality during long-distance transmission and avoid voltage and frequency fluctuations affecting the normal operation of electrical equipment.
What specific collaborative operations can be achieved with the addition of device collaboration and linkage functions in the product? How to ensure linkage stability?
The multi device collaborative linkage function can achieve three core collaborative operations: first, load collaborative allocation, which can be linked with other switch devices, transformers, and energy storage devices in the distribution network to automatically adjust the distribution plan according to load changes and achieve load balanced distribution; The second is collaborative fault handling. After discovering a fault, it can automatically link with surrounding power distribution equipment, quickly isolate the fault area, restore power supply to non fault areas, and shorten the fault handling time; The third is data collaborative sharing, which can collaborate with the distribution network IoT platform and intelligent measurement and control equipment to share operational data, achieve visualization and intelligent analysis of operation and maintenance data, and provide data support for distribution network optimization. To ensure the stability of the linkage, two points need to be done: first, strict debugging of the linkage module before leaving the factory, optimizing the communication protocol, and ensuring compatibility with various distribution equipment and platforms; Secondly, during daily operation and maintenance, the linkage module and communication lines should be calibrated and inspected every 12 months to ensure smooth communication and accurate linkage. At the same time, linkage parameters should be updated regularly to adapt to the upgrading needs of the distribution network.
How does this product meet the requirements of international top-level certification and standards for multinational mega energy projects?
To meet the requirements of international top-level certification and standards, four points need to be done: first, standard adaptation, confirming the top-level distribution standards of the target country/region in advance (such as EU EN 50062, American ANSI C37.12), manufacturers can comprehensively optimize product parameters and structural design according to the standards to ensure full compliance of the product; The second is certification application, which involves applying for top international certifications (such as EU CE certification, US UL certification, and Middle East SASO advanced certification) in advance. Manufacturers can provide complete testing reports, type test reports, and certification documents to ensure smooth product access; The third is customized adaptation. Based on the voltage, frequency, and environmental requirements of the target project, a dedicated adaptation version is customized, accompanied by multilingual (English, Arabic, German, etc.) operation manuals and maintenance manuals to ensure that local staff can operate and maintain normally; The fourth is technical support. Manufacturers can provide on-site guidance from international top technical teams to assist in project installation, debugging, and certification acceptance. At the same time, they can provide long-term global operation and maintenance support to ensure stable operation throughout the project lifecycle.
