Selection Of Lightning Surge Protector Size
With the development of science and technology, electronic devices play an increasingly important role in our lives. However, with the increasing complexity of equipment, the protection of electronic devices has become increasingly important. Among them, lightning surge protectors, as an important protection component, can effectively protect equipment from transient overvoltages such as lightning. So, how to choose the size of lightning surge protectors?
When choosing the size of a surge protector, it is generally necessary to choose according to the actual installation location of the surge protector, that is, according to the power supply. The following are some selection suggestions based on different installation locations:
If the surge protector is installed on the low-voltage side of the transformer, this is the highest level of installation location and faces the largest overvoltage. Therefore, it is recommended to use a surge protector higher than 60KA, such as 120KA or 100KA, and the model is generally 10/350US. These high KA surge protectors can effectively resist high-voltage shocks, thereby protecting the equipment from damage.
If the surge protector is installed on the side of the incoming line of the distribution cabinet, the overvoltage faced by this installation location is second. Therefore, it is recommended to use a surge protector with a surge voltage higher than 40KA, such as 80KA or 60KA, and the model is generally 8/20US type surge protector.
If the surge protector is installed on the side of the incoming line of the distribution box, the overvoltage faced by this installation position is relatively small. Therefore, it is recommended to use a surge protector with a surge voltage higher than 20KA, such as 20KA or 40KA, and the model is generally 8/20 type surge protector.
In general, choosing a suitable lightning surge protector requires considering its installation location and power supply size. The overvoltage faced will also change depending on the installation location. Therefore, when choosing a surge protector, we need to make comprehensive considerations based on the actual situation to ensure that the equipment is fully and properly protected.
Finally, we also need to note that in addition to the appropriate size, the quality and performance of the selected lightning surge protector are also important factors to consider. A good lightning surge protector can not only effectively absorb transient overvoltages, but also ensure that it will not affect the equipment when the equipment is working normally. Therefore, when choosing a lightning surge protector, we need to fully understand and evaluate the performance and quality of the product to ensure that the product we choose can meet our needs and expectations.
In this era of increasing importance of electronic equipment, the choice of lightning surge protector cannot be ignored. The correct selection of lightning surge protectors can not only help us protect high-value electronic equipment from damage, but also play an important role at critical moments. Therefore, we should be vigilant when choosing lightning surge protectors to ensure that the equipment we choose can effectively protect our equipment and data security.
In general, the selection of lightning surge protectors needs to consider multiple factors, including installation location, power supply size, and product performance and quality. Only by comprehensively considering these factors can we choose the most suitable lightning surge protector for us, thereby ensuring the safety of our electronic equipment and data.
