Due to the greenhouse effect and the El Ni ñ o phenomenon, high summer temperatures are prevalent. Excessive temperature not only leads to a decrease in power generation, but also seriously affects the operation and service life of photovoltaic modules, causing a decrease in the insulation performance of motor coil enameled wires of photovoltaic modules, cables, inverters and other electrical equipment, softening or even melting of cable insulation, resulting in circuit short circuits, causing fires in photovoltaic power stations, endangering personal and property safety. The impact of high temperature on electronic devices such as inverters is manifested as:   1) Photovoltaic power plants have electronic equipment such as inverters, which contain a large number of electronic components, integrated circuits, and high-power switching transistors. The working temperature range of civilian grade electronic components is -35 ℃~70 ℃, and the working temperature of most photovoltaic inverters is -30~60 ℃. Beyond this operating temperature range, both electronic circuits and integrated circuits will enter an unstable state. This state can cause circuit equipment to shut down in mild cases, and in severe cases, it can lead to circuit logic confusion and equipment damage.    2) There will be a large number of electrolytic capacitors in the photovoltaic inverter. In order to stabilize the voltage at the photovoltaic input terminal and prevent interference, there will also be a varying number of large capacity electrolytic capacitors. These capacitors are very afraid of high temperatures, which will gradually evaporate the electrolyte inside the capacitor, leading to a decrease in capacitor capacity and even scrapping.   3)The high-power thyristors in photovoltaic inverters are highly sensitive to high temperatures. Excessive temperatures can affect the correct operation and service life of high-power thyristors, and cause them to burn out.   Anhui Jinli PCB type surge protection deviceis widely used on the AC and DC sides of inverters, and the product fully complies with GB/T 18802.31 Low-voltage surge protective devices-Surge protective devices for specific application including d.c.-Part 31: Requirements and tests for SPDs in photovoltaic applications. Andour PCB type SPDs havepassed TUV certification andhave undergone 1000 hours of aging testing in a dual 85 ° C (temperature 85 ° C and humidity 85% environment) environment, and all aspects of performance testing are normal to ensure the safe operation of photovoltaic inverters on site.

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...
