Intelligent lightning protection system guards the "lifeline" of equipment safety

Intelligent lightning protection systems combine traditional lightning protection technology with the Internet of Things, big data, artificial intelligence, and remote monitoring, which can solvethe pain points of traditional lightning protection: passive protection, inefficient manual inspections, and difficulty in early warning of faults.And itsapplication scenarios cover areas with high lightning strike risk, high equipment value, and high security requirements. The limitations of traditional lightning protection are forcing more and more companies into a passive defense dilemma. The dilemma of traditional lightning protection is highlighted, and safety upgrade is imminent For a long time, enterprises have relied on a "passive protection + regular testing" model for lightning protection. Lightning protection equipment can only passively resist lightning strikes when they occur. Annual testing, like the blind men and the elephant, offers no real-time visibility into equipment operating status, nor does it capture fluctuations in critical data before and after a lightning strike. If lightning protection components fail (e.g., SPD aging or abnormal grounding resistance), enterprises are exposed to lightning risks without warning, potentially leading to significant losses such as production line downtime and data loss. Addressing the shortcomings of traditional lightning protection, theintelligent lightning protection system, with its innovative concept of "active defense, intelligent linkage, and full control," is revolutionizing industrial lightning protection. It achieves three key transformations: from passive to active protection, from decentralized protection to fully intelligent system protection, and from single-detection to an integrated "monitoring-analysis-warning-operation-and-maintenance" system, establishing a comprehensive lightning protection and operation and maintenance management network for enterprises. Trinity intelligent lightning protection builds a solid safety barrier The intelligent lightning protection system is based on a B/S architecture platform (including a WeChat applet for mobile phones), paired with a communication management machine and field equipment terminals, integrating IoT technology to create three core monitoring modules: Intelligent SPD online monitoring: Real-time tracking of key parameters of surge protection devices (SPDs), such as leakage current, number of operations, and temperature. Once performance degradation or failure occurs, the system immediately issues an alarm, avoiding the risk of "failure protection." Online monitoring of lightning warnings: Through technologies such as atmospheric electric field monitoring, the arrival time and intensity of lightning can be predicted in advance, and pre-treatment measures can be initiated by linking on-site equipment, thus buying valuable emergency preparation time for enterprises. Online monitoring of grounding resistance: 24-hour monitoring of the gro...

Jinli Electric's integrated lightning protection solution for power generation, grid, load and storage--building a new defense line for energy security
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...
