Lightning protection system for internet access of floating equipment

Abstract

The invention provides a floating ground equipment network port lightning protection system, which comprises a first connection terminal network port, a second connection terminal network port, a first network port transformer T1 and a second network port transformer T2, and is characterized in that a CMT0 pin of the first network port transformer T1 is connected to a mainboard ground through a fourth resistor R4, a fourth capacitor C4 and a fifth capacitor C5 which are sequentially connected in series; a CMT1 pin of the first network port transformer T1 is connected to a mainboard ground through a third resistor R3, a third capacitor C3 and a fifth capacitor C5 which are sequentially connected in series, and a CMT2 pin of the first network port transformer T1 is connected to the mainboard ground through a second resistor R2, a second capacitor C2 and a fifth capacitor C5 which are sequentially connected in series. And a CMT3 pin of the first network port transformer T1 is connected to a mainboard ground through a first resistor R1, a first capacitor C1 and a fifth capacitor C5 which are sequentially connected in series. The lightning protection device has the beneficial effect that the lightning protection capability of the floating ground equipment is improved.

Description

technical field [0001] The invention relates to floating equipment, in particular to a lightning protection system for a network port of the floating equipment. Background technique [0002] As the product application environment becomes more and more extensive, especially in remote areas, there are few lightning protection facilities, and the surge protection requirements for electronic products themselves are getting higher and higher, while the traditional lightning protection scheme is more inclined to the application of grounding products; surge The increase in level requirements has led to the fact that the lightning protection design of floating products has not met the requirements of the existing network environment. However, the direct use of traditional lightning protection solutions for floating products will lead to excessive residual voltage of the product chip and cause chip damage, which greatly affects the phenomenon. User experience. SUMMARY OF THE INVENT...

[0002] As the product application environment becomes more and more extensive, especially in remote areas, there are few lightning protection facilities, and the surge protection requirements for electronic products themselves are getting higher and higher, while traditional lightning protection solutions are more inclined to grounding product applications; surge The increase in level requirements has caused the lightning protection design of floating products to no longer meet the requirements of the current network environment. However, the direct use of traditional lightning protection solutions for floating products will lead to excessive residual voltage on the product chip, resulting in chip damage, which greatly affects the user experience
