Recently, many netizens have questioned the installation of lightning protection devices in their families. They say: do you need to install lightning protection devices in the distribution box at home? If you need to add, what kind of equipment should you choose and how to install it? Many users are ignorant about it.

Especially in recent years, the damage of electrical appliances often occurs in the family house because of lightning strike. Therefore, it is an important protection method to install lightning arrester in the residential line.

In the past, we all thought that in the event of thunderstorm weather, as long as the power plug and signal line were pulled off, the household appliances could be prevented from lightning. It is undeniable that this is safer, but sometimes it brings many inconvenience to life. Many people say that they can't play mobile phones or call in thunderstorm days. In summer, thunderstorm is frequent, and refrigerator and air conditioning should be turned off when lightning comes; If there is no one in the family, how should the electrical appliances be protected? At this time, lightning arresters need to be installed on the corresponding circuit.

For general families, three lightning arresters are needed in the family: the first is power supply lightning arrester, the second is antenna lightning arrester, and the third is signal lightning arrester. These lightning arresters can divide the electromagnetic pulse generated by lightning to limit voltage, thus protecting the home electrical appliances.

According to the experience of Lei Hao Electric for many years, the grounding of lightning arrester is connected with the grounding wire used jointly by household appliances. If the grounding wire is disconnected or loosened, the shell of household electrical appliances may be charged, which will cause the lightning arrester to fail to work normally. Meanwhile, the electrical appliances in the house should be installed as far away from the outer wall or column as possible to ensure personal safety.

Some lightning arresters should be installed according to relevant regulations. If the installation is not correct, the lightning current cannot be discharged into the earth. The grounding down lead is connected with binding wire, and it will loose and fall off after a long time; In addition, the grounding down lead is not connected firmly. When the lightning arrester is running, it may cause the connection to burn off and can not play the effect of lightning protection. Therefore, welding or bolt connection shall be adopted when installing the grounding down lead of arrester. And often carry out safety inspection, and timely handle and replace the phenomenon such as not firm.

Lei Hao Electric reminds the users here: Although there are lightning protection devices on the first and second floors such as lightning rod and lightning strip, it is still impossible to eliminate the possibility of lightning intrusion from power line, signal line and other lines. In order to create a safe home environment, it is necessary to install the home lightning arrester.
