Abstract
The utility model discloses a video and monitoring multi-functional surge protection device, which comprises a shell and a module that is arranged in the shell, wherein the module comprises a video signal lightning protection module and a power supply lightning protection module; a video signal input plug, a video signal output plug, a power supply input connector and a power supply output connector are arranged on the shell; the video signal input plug and the video signal output plug are respectively connected with the input end and the output end of the video signal lightning protection module; and the power supply input connector and the power supply output connector are respectively connected with the input end and the output end of the power supply lightning protection module. The protection device is connected in a video monitoring system in series to lead the strong surging current caused by lightning stroke or other reasons, so as to protect the equipment in the system.
Description
Technical field
The utility model relates to a kind of lightning protection device that is used on the video monitoring system, particularly a kind of video and the multi-functional Surge Protector of monitoring.
Background technology
In video monitoring system, when running into thunderbolt, cause the equipment in the video monitoring system to be burnt out easily because of powerful surge current.
Summary of the invention
The purpose of this utility model is to design a kind of video and the multi-functional Surge Protector of monitoring.
To be solved in the utility model is that video monitoring system runs into the problem that thunderbolt causes the equipment in the system to be burnt out easily.
The technical solution of the utility model is: it comprises housing, be located at the module in the housing, module comprises vision signal lightning-protection module and power lightning protection module, housing is provided with vision signal input plug, vision signal output plug, power supply input adapter and power supply out splice going splice, the vision signal input plug is connected with output with the input of vision signal lightning-protection module respectively with the vision signal output plug, and the power supply input adapter is connected with output with the input of power lightning protection module respectively with the power supply out splice going splice.
Advantage of the present utility model: in video monitoring system, be connected in series the utility model, can be promptly the powerful surge current that produces because of thunderbolt or other reason be introduced the earth, thereby protect the equipment in this system.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is circuit theory diagrams of the present utility model.
Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
As shown in the figure, the utility model comprises housing 1, is located at the module in the housing 1.Module comprises vision signal lightning-protection module and power lightning protection module, housing is provided with vision signal input plug 6, vision signal output plug 3, power supply input adapter 7 and power supply out splice going splice 2, vision signal input plug 6 is connected with output with the input of vision signal lightning-protection module respectively with vision signal output plug 3, and power supply input adapter 7 is connected with output with the input of power lightning protection module respectively with power supply out splice going splice 2.
Housing 1 is provided with the indicator light 4 of written instructions module operating state.Vision signal lightning-protection module, power lightning protection module are connected with earth connection 5.Housing 1 is a metal shell.
Operation principle of the present utility model is: the utility model is serially connected with in the video monitoring system.Under normal circumstances; the utility model and the earth are in high-impedance state; when system reaches discharge voltage of the present utility model because of the overvoltage surge that is struck by lightning or other reason produces; the utility model rapid and the earth conducting in time nanosecond immediately; powerful surge current is introduced the earth, thereby protected the equipment in this system.After this surge voltage disappeared, the utility model returned to the high-impedance state with the earth again, does not influence the work of described video monitoring system.
