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.

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. Inspect factory strength and quality management system： Anhui Jinli's products are widely used in basic industries and emerging industries such as electric power, new energy, railways, rail transit, industrial automation, metallurgy, and chemical industry. Complete certifications, worry-free after-sales, and both production capacity and the company's internal management system are at the forefront of the industry. Production strength: The company's R&D, production, and office space covers an area of 56,000 square meters, including 400 square meters of testing area. Testing capabilities: It has all the testing capabilities required by national and international standards such as GB/T18802.11/21/31, IEC61643-11/21/31, UL1449, etc., and has passed on-site testing by UL witness laboratories in the United States and TÜV Rheinland manufacturers. Laboratory certification. Product certification: EU RoHS certification, Ministry of Industry and Information Technology Tel certification, railway industry CRCC certification, EU CE certification, US UL certification, and German TÜV certification.
