Lightning protection socket In order to better protect the power supply equipment, the internal structure adds a varistor and other lightning protection components on the basis of the general socket, and the external structure adds a ground port. When the surge and induced lightning current reach the line, the varistor can play a role in discharging the current, and the ground terminal is connected to the ground wire, so that the entire circuit reaches the equipotential, we call it lightning protection. The lightning protection socket is also equipped with an overload protection device. When the current is overloaded, the lightning protection socket quickly pops up and cuts off the power supply, thereby protecting the equipment supplied by the power supply. When the number of current impacts or the current size exceeds the specified upper limit, the lightning protection components in the lightning protection socket may fail. At this time, the fault function indicator will turn on, prompting the user to replace it in time to avoid property damage or personal injury. Pay attention to check the grounding system during use, so as not to open the ground wire and reduce the protection of the lightning protection socket. The lightning protection socket is mainly suitable for the final lightning protection (overvoltage) protection of electronic and electrical equipment in low-voltage AC power supply (220V) systems, such as computers, communication equipment, high-end audio, film and television equipment, precision instruments, and instruments.
