JLSP dc Photovoltaic surge protector for PV system
14/ September 2023
JLSP dc Photovoltaic surge protector for PV system
Photovoltaic systems are exposed to large open spaces, often in the wild or on top of buildings, and charged rain clouds that accumulate over such open spaces tend to release their charge in the form of lightning. When a surge current or voltage suddenly occurs in an electrical circuit or communication line due to external interference, the surge protector can conduct and shunt the current in a very short time, thereby preventing the surge from damaging other equipment in the circuit. The upstream raw material suppliers of the photovoltaic surge protector industry chain mainly provide various raw materials and components required for surge protectors; the manufacturing of midstream surge protectors is the core link of the surge protector industry chain; the downstream application fields are electrical The ultimate beneficiary of the surge protector industry chain. In terms of technology research and development capabilities, China has strong capabilities in the research and development of photovoltaic surge protectors. Many domestic companies have invested a lot of money in technology research and development and obtained many patents; in terms of product quality, China's photovoltaic surge protectors quality of surge protector products are improving year by year. China's photovoltaic surge protector industry has achieved certain results in technological development, which are mainly reflected in three aspects: technological innovation, intelligence, and standardization. Overall, the technological development level of China's photovoltaic surge protector industry is at a relatively high level. High level, expected to continue to maintain its leading position in the future. In the future, photovoltaic surge protector industry technology will develop in the direction of safety, integration, intelligence, energy conservation, and environmental protection. Jinli Electric has always maintained the spirit of industry self-discipline, constantly innovated, and introduced new technologies to comprehensively improve the quality of lightning protection products. Thereby adapting to the ever-evolving needs of the lightning protection market.

  • Jinli PCB type SPD in inverters
    18/ August 2023
    Jinli PCB type SPD in inverters
      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.
