Abstract

The invention relates to an eight-circuit-video-signal lightning prevention device which comprises a shell, a circuit board arranged in the shell, a television signal processing module arranged on the circuit board, an electronic monitoring module and a lightning surge protection circuit. The front end face of the shell is sequentially provided with eight input ports and eight output ports, wherein the eight input ports and the eight output ports are arranged side by side mutually. The eight input ports are connected with the input end of the circuit board, and the eight output ports are connected with the output end of the circuit board. The Eight-circuit-video-signal lightning prevention device is reasonable in structural design and good in lightning prevention effect.

Description

technical field [0001] The invention relates to the field of lightning protection, in particular to an 8-channel video signal lightning protection device. Background technique [0002] Lightning protectors, also known as lightning arresters, surge protectors, surge protectors, overvoltage protectors, etc., mainly include power supply lightning protectors and signal lightning protectors (Beijing Optoelectronics Hengtong Technology Co., Ltd.). Modern electrical and other techniques to protect equipment from being struck by lightning. The lightning energy absorption in the arrester is mainly zinc oxide varistor and gas discharge tube. The currently used video signal processor does not have the effect of lightning protection. Contents of the invention [0003] The technical problem to be solved by the present invention is: in order to overcome the above-mentioned problems, an 8-way video signal lightning protector is provided. [0004] The technical solution adopted by the ...
