Recently, against the backdrop that China's power equipment aging and technical backwardness have become increasingly prominent, making it urgent to carry out upgrading and renovation to ensure the stable and efficient operation of the power system, Tenrony Electric successfully completed an old equipment upgrading and renovation project for PowerChina, effectively solving the operational pain points of its 20KV substation. This project not only helps to ensure the safe and stable operation of the substation, but also is in line with the national sustainable development strategy of energy conservation and emission reduction, and can further enhance the intelligent level of the power system. With professional customized solutions and full-process thoughtful services, the company has won high praise from the client, further deepening the strategic cooperation with State Grid fully demonstrates its formidable strength and industry-leading benchmark status in the R&D, production and service of electrical equipment.
Focusing on the core goals of "quality improvement, efficiency enhancement and safety reliability", this 20kV substation old equipment upgrading and renovation project adopted an integrated solution featuring large-scale prefabricated cabins. Compared with the traditional renovation mode, this solution greatly shortens the on-site construction period, reduces the impact of On-site operations minimize impacts on the surrounding environment and normal operations, and effectively implement the efficient, energy-saving and green power construction concept. The project is equipped with a complete set of core electrical equipment, covering high voltage switchgear, DC screen, distribution transformer and other key facilities. All equipment is manufactured in strict accordance with national and industry standards, accurately meeting the core needs of PowerChina's old equipment upgrading, as well as ensuring the stable and safe operation of the substation upon completion of renovation.
To ensure the efficient implementation and successful delivery of the project, Tenrony Electric leveraged its whole-industry-chain integration advantages to provide one-stop full-life-cycle services, encompassing precise scheme design, customized equipment manufacturing, professional logistics and transportation, on-site standardized installation, accurate commissioning, and post-renovation operation maintenance. Operation and Maintenance (O&M). In the design stage, the team conducted in-depth on-site surveys and investigations, optimized the scheme in light of actual operating conditions, balancing practical applicability and long-term developmental needs; In the production stage, the company strictly implemented the quality control system, controlling every link of equipment production to ensure that the equipment performance meets the standards and the quality is excellent. Specifically, in the cutting process, the staff carry out operations in accordance with the cutting list, and after the first inspection, self-inspection and mark transplantation, they submit to the full-time inspector for verification before proceeding to the next process; in the assembly and welding process, the cold working section takes anti-deformation measures during assembly and spot welding, and after welding, the deformed parts are corrected to meet the standard before passing the inspection; in the final assembly and debugging stage, the full-time inspector measures the motor temperature, noise and operation status, and works with the technical department to deal with any abnormal conditions to ensure normal operation of the equipment.; in the installation stage, a professional on-site technical team A construction team was set up to efficiently promote the construction progress and minimize the interference to the normal on-site operation; in the after-sales stage, a comprehensive service mechanism was established to quickly respond to various needs, fully ensuring the smooth delivery of the project and its long-term stable operation in the future. Just like the comprehensive automation transformation of the 220kV old substation of Huizhou Power Supply Bureau, this practice successfully solved the core problems such as low operation efficiency caused by low automation level and prominent safety hazards due to aging equipment of the old substation. For example, some old substations like those of State Grid Shenyang Power Supply Company had problems such as manual operation of knife switches and frequent failures of transformer core ammeters. After transformation, not only the operation efficiency is improved, but also the safety is enhanced, reducing maintenance costs and bringing better economic benefits for the power supply enterprise.
The successful This cooperation with PowerChina is not only another benchmark practice achievement of Tenrony Electric in the field of old power equipment upgrading, following the example of similar projects like the power equipment renovation and renewal project for old residential communities in Jinan's main urban area, but also further deepens the strategic cooperation friendship with State Grid, laying a solid foundation for the two parties to expand broader and deeper cooperation space in the future. Going forward, Tenrony Electric will continue to focus on the R&D, production and services of electrical equipment, advance core technologies, optimize the service system, continuously improve core competitiveness, and inject strong momentum into the high-quality development of the power industry with better products and more professional services.
