• Lightning protection transformation of traditional industries before the rainy season
    May 12, 2023 Lightning protection transformation of traditional industries before the rainy season
    Meiyu refers to the continuous cloudy and rainy weather phenomenon that occurs from early June to mid-July in the Gregorian calendar every year. At this time, due to the long-term rainy and sometimes sunny and high-humidity weather, the utensils in the home are prone to mold, which is also called mildew rain among the people. In GB/T 21431-2015 "Technical Specifications for Testing Lightning Protection Devices of Buildings", the requirements for regular testing are as follows: The inspection interval of lightning protection buildings with explosion and fire hazard environments is 6 months, and the inspection interval of other buildings is 12 months. Therefore, before the rainy season comes every year, the high and low voltage electrical equipment in the factory area must be inspected and transformed for lightning protection. From April 20th to 23rd, 2023, the Anhui Jinli lightning protection technical service team came to Yichang City, Hubei Province to inspect the components in the high and low voltage cabinets of Xingfa Group Hubei Xingrui Silicon Material Co., Ltd. and Huaxin Cement (Zigui) Co., Ltd. Use for understanding and exploration. After communication and investigation, it was found that during the construction of the high and low voltage power distribution room more than ten years ago, high and low voltage lightning protection products had been installed in accordance with the requirements of the then national standard GB50057-2000, and all of them were the ones in the product diagram of Anhui Jinli. Surge protector JLSP-100 and current transformer secondary side overvoltage protector JLC-6, some products are still working normally. Based on the reason of the product's service life, the original generation of current transformer secondary side overvoltage JLC-6 was replaced by the second generation product JLCII-6. The performance of the new product has been significantly improved, and it can effectively prevent the secondary open circuit of the current transformer or the primary winding. Accidents caused by abnormal current flow. In accordance with GB50057-2010 "Building Design Code", the T2 surge protector in the incoming cabinet is upgraded to a T1 surge protector. According to GB51348-2019 "Electrical Design Standards for Civil Buildings", the lightning protection combination of MCB+SPD is upgraded to SCB+S, which solves the problems of high current impact misoperation and small power frequency current refusal, making the lightning protection effect better and allowing Customers are protected from lightning. Finally, we communicated with customers about Anhui Jinli's intelligent lightning protection system: lightning early warning monitoring technology, SPD intelligent monitoring technology, and grounding resistance monitoring technology, transforming passive lightning protection to active defense, transforming decentralized lightning protection and full intelligent protection, and building a three- dimensional It is hoped that the...

  • Introducing our outstanding Panoramic Lightning Protection Solution
    March 05, 2023 Introducing our outstanding Panoramic Lightning Protection Solution
    Energy storage is widely used at the source, grid, and load ends of power systems, and is an important guarantee for wind and solar consumption. However, the volatility, intermittency, and randomness of photovoltaics pose challenges to the stability of the power system, and the urgency of energy storage construction has become increasingly prominent. The Ulan Buhe Desert in Dengkou County, Bayannaoer City, Inner Mongolia Autonomous Region is one of the eight major deserts in China. The kilowatt photovoltaic sand control project is simultaneously equipped with 45,000 kilowatts of energy storage. The 45,000-kilowatt energy storage projects of SPIC Golden Sunshine Storage Power Station and Xuheng Photovoltaic Storage Power Station are divided into 12 sub-units. The energy storage system is divided into water-cooled energy storage and air-cooled energy storage according to different cooling methods. Water-cooled energy storage is designed with a higher IP level for water cooling, and the outdoor energy storage system is formed in the form of an outdoor cabinet; due to the air-cooled cooling method and lower IP level design, the outdoor energy storage system is formed in the form of a container for air-cooled energy storage. This project adopts The ones are water-cooled. Whether it is an outdoor cabinet outdoor energy storage system or a container outdoor energy storage system, it will be affected by lightning weather outdoors, which will cause damage or malfunction of electrical and electronic systems. Therefore, it is necessary to design a suitable lightning protection spd scheme for outdoors to protect the safety of electrical and electronic systems, so as to ensure the safe and stable operation of the system in the lightning strike environment. In order to ensure its safe and reliable operation, lightning arresters or surge protectors are installed on the high-voltage side of the box-type transformer, the low-voltage side of the box-type transformer, the measurement and control of the box-type transformer, and the energy storage battery compartment for lightning protection. Anhui Jinli is based on the enterprise development concept of "adhering to originality", is committed to the safety of electricity use in electrical systems, focuses on lightning protection technology in electrical systems, and develops special surge protector series in the fields of wind, wind, storage and charging, etc., for new energy and The lightning protection of the energy storage system provides professional solutions to ensure its safe and stable operation.
