It is understood that many users of lightning protection devices respond that they have little knowledge of the process of installing lightning protection devices in the home, especially if there are few things to be aware of in the installation process. What precautions should be taken to install lightning protection devices in the home? How to properly install the lightning protection device? Kejia Electric recommends:
1, before the mine to be installed over Test <br> <br> mine before installation, first check the technical parameters, business logo and brand differentiation and other information on business products, while once on mine Handover tests to ensure that all aspects of performance and all parts intact. At the same time, during the installation of the surge protector, the upper end of the arrester is connected to the phase conductor and the lower end of the grounding protection cable cannot be installed upside down; the installation distance must not be less than the relevant provisions of the installation design standards; it should be noted that the arrester should be checked regularly. The damage or grounding is found to be inconvenient and must be replaced promptly.
2. Grounding deflector of lightning arrester should meet the requirements
The grounding conductor of the lightning arrester shall be installed in accordance with the relevant regulations. If the lightning current is not correctly installed, it cannot be discharged into the earth. Other ground lead wires are connected by a wire tie, which will loosen and fall off after a long time. In addition, the ground lead wire is not firmly connected. When the lightning arrester is running, it may cause the connection point to burn, and it cannot play lightning protection. effect. Therefore, the grounding deflector for installing the arrester should be welded or bolted.
3, insulator iron feet to be properly grounded
The insulator iron foot of the high-voltage line is correctly grounded. This is to prevent the lightning current from increasing steeply, and the voltage rise speed of the lightning arrester is fast, and the lightning protector has no time to discharge, which causes the lightning to directly hit the protected distribution transformer. On, burn out the insulation equipment. Only properly grounded can withstand the lightning current generated by the steep slope and ensure the safety of distribution transformers.
4, distribution transformers need lightning protection, beware of over-voltage
Both the high and low voltage sides of distribution transformers must be protected by lightning protectors. Their purpose is to prevent overvoltages caused by forward and reverse conversion. Only in this way can distribution transformers be protected from lightning. It should be noted here that the grounding wire of the high- and low-voltage surge protectors and the transformer housing must be grounded together, and they must be solid and cannot be loosened, otherwise they cannot play the role of lightning protection.
Generally, the lightning protection devices for indoor and outdoor households are installed with lightning protection and indoor lightning protection. There are lightning rods and lightning protection cables for outdoor lightning protection. However, they cannot completely protect indoor electrical equipment from lightning strikes. Therefore, there must be lightning protection devices in the room to protect them. After years of experience in research and development of lightning protectors by Kejia Electric, household lightning protection can be achieved only by layer protection in order to maximize the protection of electrical equipment and reduce the damage caused by lightning.
