  • Anhui Jinli Electrical Lightning Protection Encyclopedia - Comprehensive Lightning Protection for Buildings
    March 11, 2024 Anhui Jinli Electrical Lightning Protection Encyclopedia - Comprehensive Lightning Protection for Buildings
    The lightning protection device installed on the building can only protect the building from being directly damaged by lightning. It is called external lightning protection; it cannot protect the electrical equipment in the building from being damaged by lightning overvoltage or surge voltage generated by lightning induction. , it is called internal lightning protection. Schematic diagram of comprehensive lightning protection for buildings Lightning overvoltage can be generated in two ways: when lightning occurs in the distance, the transient electromagnetic field generated by the lightning induces a transient surge voltage on the power supply line or signal line, which can be conducted along the line to the electrical equipment of the building. The insulation of electrical equipment is damaged; the other is that lightning or lightning strikes near the building directly strike the building. A strong transient electromagnetic field is generated around the lightning current entering the ground, which is directly induced on the power supply lines or signal lines of the electrical equipment in the building. Produce transient overvoltage and damage the insulation of electrical equipment. The energy of this surge is much greater than that of a surge induced and conducted on a wire by a distant lightning strike into a building. After the building is equipped with an external lightning protection device, the air-termination device on the roof plays a role in guiding lightning. Although the lightning protection device can safely discharge the lightning current into the ground, protecting the building. However, the strong transient electromagnetic field generated by the lightning current caused by direct lightning strikes increases the risk that the insulation of electrical equipment in the building will be damaged by the transient overvoltage induced in power lines and signal lines. This overvoltage can also cause hazards due to impedance coupling from grounding devices along distribution lines and into adjacent buildings. As a well-known lightning protection brand in China, Anhui Jinli has been committed to the electrical safety of electrical systems and focused on lightning protection technology for electrical systems. Among them, the research and development and production of lightning arresters are at the forefront of the industry.

    March 04, 2024 How to choose a suitable surge protector factory?
    With the continuous development of social science and technology, surge protectors (SPD) have become an indispensable electrical protection component in modern buildings and important facilities. So, how to choose a surge protector factory? 1. Regarding product questions: The selection of a surge protector mainly depends on the following parameters: Maximum continuous operating voltage (Uc): The maximum effective AC power frequency voltage or DC voltage that is allowed to be permanently applied to the surge protector. Its value is equal to the rated voltage. Maximum impulse current (Iimp): Usually the impulse current test with 10/350us waveform is used, which belongs to the Class I classification test, which means that the SPD can withstand a maximum current impulse. Maximum discharge current (Imax): According to the 8/20us waveform test, the test belongs to the Level II classification test. The maximum discharge current that can be withstood through the action load test. Protection voltage Up: The product should be marked with protection voltage Up. Up should be less than the measurement limit voltage and at the same time less than the impulse withstand voltage value of the equipment. 2.

  • How to protect photovoltaic power plants from lightning?
    February 26, 2024 How to protect photovoltaic power plants from lightning?
    With the widespread use of new energy in recent years, wind energy, solar energy, hydropower, etc. have gradually occupied a certain market in the energy market, effectively alleviating the energy crisis caused by the depletion of traditional energy sources. Among them, the widespread use of solar energy occupies an important position in the new energy market. Not only industrial and commercial power generation but also residential solar power generation is becoming more and more popular in the market. Therefore, lightning protection for solar energy is extremely important. The main steps for lightning protection of photovoltaic power plants are as follows: 1. According to the range, height, and installation position of the solar cell array, and by the requirements of GB50057 "Design Code for Lightning Protection of Buildings", lightning protection pins, lightning strips, lightning wires, and lightning nets should be installed to prevent direct lightning strikes. The height and number of lightning rods should be calculated according to the rolling ball method and installed in a reasonable layout. 2. Large photovoltaic power stations can be equipped with air-termination pins and towers to protect against direct lightning strikes. The air-termination pins installed in large-scale photovoltaic power stations should be at least 3m away from the edge of the photovoltaic cell module bracket. The grounding points of the down conductor for direct lightning protection and the down conductor for safety protection on the ground network should be at least 10m apart. The cross-sectional area of the lightning-receiving wire should be determined from the length and width of the photovoltaic cell module group and is generally not less than 25mm2 steel strand. 3. When photovoltaic cell modules are installed on the roof slope, lightning strips should be installed. The air-termination strap should not be connected to the aluminum alloy frame and brackets around the solar panel. The air-terminating tape should be installed with a down conductor every 18m to connect to the ground grid. 4. The aluminum alloy frames and brackets around the solar panels should be connected and connected at equal potential. According to the size of the battery module, more than two grounding wires should be installed through the steel pipe or connected to the grounding grid with a shielded wire as a safety protection ground. 5. The entry points of the down conductor for direct lightning protection and the down conductor for safety protection on the ground network should be more than 10m apart to prevent high-potential counterattacks from lightning strikes. As an innovative lightning protection enterprise in China, Jinli Electric has focused on the R&D, production, testing, and basic research of surge protectors and lightning protection-related products for 18 years since its establishment, with users as the center. Not only provide high-quality products that meet user needs but also ...

  • The difference between a backup protector and a surge protector
    February 18, 2024 The difference between a backup protector and a surge protector
    As a well-known lightning protection brand in China, Anhui Jinli has been committed to the electrical safety of electrical systems and focused on lightning protection technology for electrical systems. It has 18 years of research and development experience. The backup protectors and surge protectors produced are of various types, novel styles, and high quality, which can meet the needs of different customers. To better serve customers, it should be noted that backup protectors and surge protectors are not the same. They are different in function, installation location, and role. 1) Surge protector. Also known as overvoltage protectors, they are used to protect electronic equipment from overvoltage damage. When voltage surges or transients occur in the circuit, surge protectors can guide these overvoltages to the ground or normal power supply. To protect the protected equipment, it is usually installed in front of the terminal equipment. 2) Backup protector. It is a backup power device that is used to provide a short-term power guarantee when the main power supply fails or the power supply is interrupted. It can enable the power equipment to maintain normal operation under abnormal conditions such as power outage, unstable voltage, high or low frequency, etc. Electrical equipment operates normally and is usually installed in front of a surge protector. It should be noted that the back protector must be installed. It cooperates with the surge protector and is indispensable to protect the circuit from damage.
