Abstract
The utility model discloses a novel single-circuit video surge protection device which comprises a video surge protection circuit. The video surge protection circuit comprises a primary rapid discharge tube, an ultra-rapid recovery diode discharge circuit and a piezo-resistor. Two ends of the primary rapid discharge tube are respectively connected with two ends of the ultra-rapid recovery diode discharge circuit. A grounding end of the primary rapid discharge tube is connected with the ground through an ungrounded end of the piezo-resistor. The novel single-circuit video surge protection device has the advantages of green environmental protection, energy saving and emission reduction which conform to requirements of a conservation-mined society, large discharge current capacity and multilevel protection, as well as wide scope of access to Alternating Current (AC)/Direct Current (DC) voltage, fast speed which reaches a nanosecond level; enhancement of signal transmission and low residual voltage.
Description
Technical field
The utility model relates to a kind of lightning protection device, relates in particular to a kind of novel single channel video lightning protection device, belongs to electric field.
Background technology
Safety is a kind of basic social demand, and this demand is growing along with the raising of deep and the development and the living standards of the people of social economy's reform.Organization Behavior think people's demand be with different levels, be constantly to increase and to high-level development, after this primary demand of existence was met, safety and stability was the demand that certainly leads to.This " safely " is generalized concept, and it comprises the stable of work, income, and healthy guarantee etc. more be close to the notion of public safety, but the safety of the safety, particularly lives and properties of life are important contents.We are being in the epoch of a change, and these epoch will bring unprecedented view of time and space, information view, values to us.Unprecedented variation all can take place in social structure, economic activity, information propagation, interpersonal communication etc., new notion, new demand will occur at public safety field.Along with the progressively propelling of safety China Reconstructs, the application of watch-dog and be fit into the universalness stage, and the long distance control system that subjects to indirect lightning strike is badly in need of installing simple-to-maintain lightning protection device easily.Supervisory control system mainly is made up of front end, transmission and terminal three parts, and thunderbolt destruction approach is divided into direct lightning strike, lightning wave is invaded and lightning induction.Already present in the market common lightning protection device is just merely to the protection of power supply, and holding wire and control line all will receive badly damagedly when thunder and lightning is attacked, and its ground path can have a strong impact on the transmission of video signals generation.
The utility model content
To the deficiency that prior art exists, the utility model technical problem to be solved is, a kind of novel single channel video lightning protection device is provided, install simple, maintenance cost is ultralow and can strengthen the transmission speed at terminal before and after the Long-distance Control.
For solving the problems of the technologies described above, the technical scheme that the utility model is taked is, a kind of novel single channel video lightning protection device, and it is made up of the video lightning protection circuit; Said video lightning protection circuit is made up of one-level repid discharge pipe, Ultrafast recovery diode discharge circuit and piezo-resistance; The two ends of said one-level repid discharge pipe are connected with the two ends of Ultrafast recovery diode discharge circuit through resistance respectively, and said one-level repid discharge pipe earth terminal is connected with ground through the non-earth terminal of piezo-resistance.
Optimize, above-mentioned novel single channel video lightning protection device, its Ultrafast recovery diode discharge circuit are connected with two other Ultrafast recovery diode reverse parallel connection circuit through a diode after by two Ultrafast recovery diode reverse parallel connections.
The utility model is made up of the video lightning protection circuit, and the video lightning protection circuit adopts the repid discharge pipe, and the high pressure that methods such as piezo-resistance and fast recovery diode produce thunderbolt has carried out reliably discharge over the ground, thereby has effectively protected follow-up circuit.The video lightning protection circuit all is to adopt the repid discharge pipe that the high pressure that thunderbolt produces is once discharged earlier, adopts Ultrafast recovery diode that residual voltage is discharged then.This mode had both guaranteed the high pressure that thunderbolt produces has been carried out effective discharge, had also prevented the interference that discharge circuit produces communication data, thereby had protected follow-up data communication circuit.
The basic technology route of the utility model lightning protection device is to be the groundwork mode with the leakage current, and when delimiting when voltage or above one, the inner controller of lightning protection device forms path, makes surge from the PE line is released the earth, forms protective effect.Can implement protection to video camera, The Cloud Terrace, connection host line respectively; High pass flow can reach 10000VA, and minimum reaction speed is fast to AC/DC6V, can fully realize protection; And can strengthen Long-distance Control front and back terminal transmission speed, be applied in the middle of the various up-to-date video monitoring systems.The utility model also has following characteristics in addition: (1) environmental protection, and energy-saving and emission-reduction meet the saving social desirability; (2) discharge capacity is big, can realize multi-stage protection; (3 access AC/DC voltage ranges are wide; (4) speed fast (nanosecond); (5) enhancement signal transmission; (6) residual voltage is low.
Description of drawings
Below in conjunction with accompanying drawing and embodiment to the utility model further explain;
Fig. 1 is the circuit theory diagrams of the utility model.
Embodiment
As shown in Figure 1, the utility model is a kind of novel single channel video lightning protection device, and it is made up of the video lightning protection circuit.Its video lightning protection circuit is made up of one-level repid discharge pipe GAP1, Ultrafast recovery diode discharge circuit and piezo-resistance R3; The two ends of said one-level repid discharge pipe GAP1 are connected with the two ends of Ultrafast recovery diode discharge circuit through resistance R 1, resistance R 2 respectively, and said one-level repid discharge pipe GAP1 earth terminal is connected with ground through the non-earth terminal of piezo-resistance R3.Its Ultrafast recovery diode discharge circuit is connected with two other Ultrafast recovery diode D3 and D4 reverse parallel connection circuit through a diode D5 after by two Ultrafast recovery diode D1 and D2 reverse parallel connection.
Certainly, above-mentioned explanation is not to be the restriction to the utility model, and the utility model also is not limited to above-mentioned giving an example; Those skilled in the art; In the essential scope of the utility model, the variation of making, remodeling, interpolation or replacement all should belong to the protection range of the utility model.
