In accordance with the guidance of "Transportation and Supply Equipment Letter No. 325" and "Transportation and Supply Equipment Letter No. 240" issued by the Transportation Bureau of China Railway Corporation, GB 50057 "Design code for protection of Structures against lightning" and GB 50343 "Technical code for protection of building electronic information system against ligtning", Anhui Jinli Electric Tech. Co., Ltd has fully combined the two basic principles of lightning protection zoning and lightning protection classification, and launched the "distributed" lightning protection system and the "centralized" lightning protection system. It can effectively suppress strong lightning from invading the secondary system of the traction substation and prevent the secondary system equipment of the traction substation from being damaged by strong lightning intrusion.  The products including surge protection devices, isolation transformer cabinet, comprehensive intelligent lightning protection screen of Anhui Jinli Electric Tech. Co., Ltd. can meet the relevant technical requirements and standards and provide effective lightning protection measures.

To further enhance the expertise and efficiency of our production team, we recently held our first Production Skills Competition. The competition focused on key processes in manufacturing low-voltage surge protection device, covering soldering, assembly, testing, and more. It showcased our employees’ exceptional craftsmanship and unwavering commitment to high-quality products. Ⅰ:A variety of exciting events Varistor Assembly Long and short electrode assembly Remote static and static electrode assembly Products short electrode welding Board manual plug-in Ⅱ:Cross-departmental collaboration, create success This event not only inspired innovation and teamwork among our staff but also strengthened our leadership in the SPD industry. We believe it is these meticulous details that ensure our products are safe and reliable for our customers. As a leading provider of surge protector solutions, we remain dedicated to addressing customer needs through continuous innovation and stringent quality control. Looking ahead, we will keep advancing skills and technologies to deliver even greater value to our customers.

Ⅰ：Energy storage terms Stored energy：The process of storing energy through a medium or device and releasing it when needed. Through flexible charge and discharge control, it realizes the matching of production capacity and energy consumption in time and space. From the perspective of power system, energy storage can be divided into power generation side/power supply side, power grid side, and user side energy storage, of which power supply side and power grid side energy storage is also known as pre-table energy storage or large storage Pre-sheet energy storage：Energy storage that is directly connected to the power grid and has independent power and electricity meters; Otherwise, it is post-table energy storage, and user-side energy storage is also called post-table energy storage. User-side energy storage is divided into industrial and commercial energy storage and home energy storage. Domestic user-side energy storage mainly refers to the energy storage system applied in the majority of industrial and commercial customers, energy storage equipment can be simply understood as a large charging treasure. Charge when the electricity price is low, discharge when the electricity price is high for enterprise production, and earn the difference between peak and valley electricity prices, thereby reducing the cost of electricity for enterprises. Peak regulation：Transfer excess electricity from low-power areas to low-power areas. Because electricity cannot be stored on a large scale, it is generally necessary to use as much electricity as is generated. When the power generation of a region is constant, and the power here is not used up, it is necessary to transfer the excess power to the power shortage area through dispatch, or is the common pumped storage Frequency modulation：For example, the rated frequency stipulated in China is 50Hz, but the electrical appliances in production and life are complex and diverse, and the start-up of the machine will affect the power grid frequency, which requires frequency modulation to improve the power quality. PCS(Power Conversion System)：Realize the power conversion between the grid and the battery, and monitor and manage the exchange process. It can control the charging and discharging process of the battery, carry out AC/DC transformation, and directly supply AC load in the case of no power grid. PCS is composed of DC/AC bidirectional converter, control unit, etc BMS(Battery Management System)：It is mainly used for battery pack monitoring, calculation, communication and protection. It mainly consists of battery management chip, analog front end, embedded microprocessor, and embedded software EMS(Energy Management System)：It can realize real-time monitoring and intelligent management of all equipment in the system. Realize data collection, storage, processing, upload, operation control, operation strategy formulation, and so on, and carry out overall information-based monitoring and management Ⅱ：Lightning protectio...
