Abstract
The utility model discloses an arrangement structure of a lightning protection device. The arrangement structure is arranged on a base plate of a lightning protection box. The arrangement structure comprises a terminal, fuses and lightning protection devices, which are sequentially and electrically connected with one another, wherein the connecting distances between the fuses and the terminal are equal, and the connection distances between the lightning protection devices and the fuses are equal. The lightning protection devices are voltage dependent resistors; the lightning protection devices are electrically connected with one another in parallel; and the fuses are electrically connected with one another in parallel. After the arrangement structure is used, the plurality of fuses are connected to one terminal, the fuses are connected with one another in parallel to averagely divide the current, the distances between input ends of the fuses and the terminal are equal, the fuses are connected with the lightning protection devices, the lightning protection devices are connected with one another in parallel, and the distances between input ends of the lightning protection devices and output ends of the fuses are equal, and the current is averagely distributed from input ends of wires. Therefore, the energy can be averagely distributed due to the fuses and the lightning protection devices which are connected in parallel. The impact-resistant times can be increased, and the service life can be prolonged.
Description
Technical field
The utility model relates to a kind of thunder resisting equipment/product, particularly relates to a kind of arrangement of lightning protection component.
Background technology
Along with the development of technology and the progress of society, people are more and more higher to the requirement of thunder resisting equipment, in long-term practice was excavated, industry lacked equipment and the technology that anti-repeatedly lightning surge impacts, and the lightning protection component exploitation that can tolerate repeatedly the lightning surge impact is following inevitable trend.Lightning protection component, particularly traditional MOV design on circuit board during in parallel the use homogeneous word arrange, at true lightning surge or when doing the thunderbolt laboratory, because of the large electric current of high frequency with nanosecond speed conduct to each SPD lightning-protection module, different in size due to the current delivery path, the sequential that can form pressure-sensitive action is inconsistent, in the situation that multiple-pulse is impacted, cause the first explosion of shortest path SPD, energy distribution is uneven.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, and a kind of arrangement of lightning protection component is provided, and beginning from input is the mean allocation electric current, makes the equipartition of energy, shock-resistant increased frequency, and the life-span is elongated.
In order to achieve the above object, the technical solution adopted in the utility model is: a kind of arrangement of lightning protection component, be arranged on the lightning protection box base plate, the terminals, fuse and the lightning protection component that comprise successively mutual electrical connection, equate with the distance that is connected of terminals between described fuse, equate with the distance that is connected of fuse between described lightning protection component.
Further, described lightning protection component is piezo-resistance.
Further, between described lightning protection component for being connected in parallel.
Further, between described fuse for being connected in parallel.
Compared with prior art, the beneficial effects of the utility model are: beginning from the wiring input is the mean allocation electric current, and fuse and lightning protection component by parallel connection make the equipartition of energy, shock-resistant increased frequency, and the life-span is elongated.
Description of drawings
Fig. 1 is structural representation of the present utility model;
Fig. 2 is current direction schematic diagram of the present utility model.
Embodiment
Be elaborated with reference to accompanying drawing below in conjunction with embodiment, in order to technical characterictic of the present utility model and advantage are carried out more deep annotation.
Structural representation of the present utility model as shown in Figure 1, 2, a kind of arrangement of lightning protection component, be arranged on lightning protection box base plate 1, the terminals 2, fuse 3 and the lightning protection component 4 that comprise successively mutual electrical connection, equate with the distance that is connected of terminals 2 between described fuse 3, equate with the distance that is connected of fuse 3 between described lightning protection component 4.
Further, described lightning protection component 4 is piezo-resistance.
Further, between described lightning protection component 4 be in parallel the electrical connection.
Further, between described fuse 4 be in parallel the electrical connection.
As shown in Figure 2,3 fuses 3 of terminals 2 accesses, and be parallel way between fuse, divide equally electric current, and the input of fuse equates with distance between terminals, fuse is connected with lightning protection component 4, and between lightning protection component 4 for being connected in parallel, the input of lightning protection component 4 equates with the output distance of fuse 3, lightning protection component 4 is piezo-resistance, and beginning from the wiring input is the mean allocation electric current, and fuse and lightning protection component by parallel connection make the equipartition of energy, shock-resistant increased frequency, the life-span is elongated.
Above content is in conjunction with concrete optimal way further detailed description of the utility model, should not assert that concrete enforcement of the present utility model is confined to above explanation.For those skilled in the art, without departing from the concept of the premise utility, can also make some simple deduction or replace, within the protection range that the claim that all should be considered as being submitted to by the utility model is determined.
