Amidst the rapid development of energy transformation and smart grids, lightning disasters pose an increasingly severe threat to power systems. To effectively address this challenge, Jinli Electric has launched an integrated lightning protection solution for power generation, grid loading, and storage. This comprehensive, systematic protection system provides an impenetrable safety barrier for energy systems. Comprehensive lightning protection, every link cannot be omitted The integrated power-grid-load-storage system is like a sophisticated "energy ecosystem," with power supply, grid, load, and energy storage all closely linked. Problems in any one of these links could trigger a chain reaction. 1.Power supply :Jinli Electricprovides a full set of high-quality and reliable lightning protection solutions for photovoltaic and wind power systems, which can effectively protect all components of wind power and photovoltaic systems from lightning. 2. Power grids: The transmission lines crisscross mountains and rivers, making them a prime target for lightning strikes. Line arresters and monitoring devices act as gatekeepers, constantly protecting against lightning overvoltages and ensuring unimpeded power transmission. 3. Load: Industrial equipment and precision instruments, for example, can be affected by small fluctuations caused by induced lightning, potentially disrupting normal operation. Installing a suitable surge protection devices like putting lightning protection armor on the equipment. For rail transit systems, SPDs are the core of lightning protection. Isolation transformer cabinets and power supply lightning protection cabinets also perform their respective functions, working together to build a lightning defense line. 4. Energy storage: Battery packs and converters are more sensitive to lightning. In energy storage systems, battery surge protection directly impacts system safety and lifespan. Intelligent lightning protection boxes specifically designed for energy storage utilize high-end lightning protection units with high current flow and low residual voltage. These units monitor their operating status and lightning data. Installed within prefabricated battery compartments, these boxes effectively protect against lightning overvoltages. Core of the solution: Four-dimensional integration, precise prevention and control This solution innovatively integrates the lightning protection requirements of four major links: power supply, grid, load, and energy storage. It is a full life cycle management system covering design, selection, implementation, and monitoring: 1.Lightning protection design: Based on regional lightning activity patterns and system characteristics, we tailor differentiated protection solutions to reduce lightning strike risks at the source; 2.Equipment selection: Strictly select lightning protection devices (such as SPDs and lightning arresters) that meet international standards to ensure the reliability of key equipm...

On the sunny day of May 6, Anhui Jinli Electric held a wonderful team-building activity with the theme of "Hot early summer, fun sports" at "My Gardener" in Feixi. This activity perfectly integrated fun sports with corporate culture, allowing employees to enjoy the joy of sports and also showing the unique corporate charm of Jinli Electric. Trolleybus: Keeping the same frequency and reaching the destination During the activity, the team members walked side by side with balloons on their heads. Only by keeping in step and cooperating throughout the process can mistakes be avoided. This is just like Jinli Electric's mission - in the face of complex technical challenges, only by resonating in the whole process of R&D, production, and after-sales can the promise of "protecting users from lightning intrusion" take root. Team Pyramid: Every goal is a "star" held together The 14 balls need to be placed on the top of the tower by the team pulling the ropes, just like every order and every goal ofJinli Electric, which requires the cooperation of marketing, technology, R&D, business, product and other departments. "Every ball on the top of the tower is the cornerstone of our vision of 'creating the world's best lightning protection brand'." Fun competition: Sports activate vitality, health is fighting power The "shouting in unison" of land dragon boat racing, the "quick eyes and quick hands" of Tetris, the "juggling race" with stars centering on the moon... Every event of the fun sports meeting allows employees to release stress through running and collaboration. With vitality as the sail, set sail towards "the best in the world" The setting sun draped a golden coat over "My Gardener", and this team building full of laughter and insights came to an end. But Jinli people's adherence to "safety" and "health" continues - just as the slogan shouted by everyone at the end of the event: "Hot early summer, enjoy sports; Jinli lightning protection, we are the best!" In the future, Jinli Electric will continue to use "original technology" as its paddle and "healthy team" as its sail to forge ahead on the journey of "creating the world's best lightning protection brand". Because we firmly believe that when every Jinli person becomes a guardian of safety and a practitioner of health, those "pyramid tips" that are jointly lifted up will eventually illuminate the sea of stars in the field of lightning protection.

Photovoltaic DC 2000V technology refers to the technology of transmitting and applying the DC power generated by photovoltaic modules at a voltage level of 2000V in photovoltaic power generation systems. Its working principle is based on the basic principle of photovoltaic power generation, that is, using the photovoltaic effect. When sunlight shines on photovoltaic modules, photons interact with electrons in semiconductor materials, allowing electrons to obtain enough energy to generate electrons and holes that move in a directional manner under the action of the electric field to form DC power. In the photovoltaic DC 2000V system, through special circuit design and component selection, the low-voltage DC power output by photovoltaic modules is boosted and transmitted in the form of 2000V high-voltage DC power. In photovoltaic systems, the improvement of voltage levels is an important direction of technological development. From the early lower voltage levels, it has gradually developed to the 1500V system that is now widely used. At present, photovoltaic DC 2000V technology is gradually emerging. Compared with the traditional 1000V and 1500V systems, photovoltaic DC 2000V has significant advantages. In theory, higher voltage can effectively reduce the current, thereby reducing the resistance loss during the transmission process and improving the overall efficiency of the system. From the perspective of voltage level, 2000V is significantly higher than 1500V and 1000V. In terms of power transmission, according to the power formula P = UI (where P is power, U is voltage, and I is current), under the same power transmission requirements, the higher the voltage, the smaller the current. According to Joule's law Q = I²Rt (where Q is heat, i.e., lost energy, I is current, R is resistance, and t is time), the reduction in current will greatly reduce the resistance loss in the line. Under the same line resistance and transmission time, the line loss of the 2000V system can be significantly reduced compared to the 1500V system. This can bring considerable economic benefits to large-scale photovoltaic power stations. In addition, the 2000V system also has certain advantages in equipment cost and floor space. Due to the reduction in current, thinner cables can be used, reducing the cost and weight of the cables, while also reducing the space required for cable laying and the difficulty of construction. At present, technologies such as artificial intelligence, digital twins, and cloud computing are constantly innovating, digital technology is deeply integrated with new energy system technology, and application scenarios are constantly enriched, achieving cost reduction and efficiency improvement throughout the photovoltaic life cycle. 2000Vplug-in SPDs used in combiner boxes,PCB type SPDs in inverters, line lightning arresters, and supporting monitoring terminals have emerged. Following the development trend of the industry,Anhui Jinli has m...
