Abstract
The utility model discloses an anti lightning stroke device for electric appliances. The utility model is characterized in that a circuit board is provided with two serration type electric discharge metal plates, two fuse wires, two induction coils, a capacitor, and a voltage dependent resistor; the casing is provided with a terminal of the electric appliances; serration tips of the two serration type electric discharge metal plates correspond to each other and have a certain gap; the two serration type electric discharge metal plates are respectively provided with input supply terminals. The utility model has the function that the utility model can prevent household electric appliances from damaging by thunder and lightning when the household electric appliances are used in rain. The utility model has the advantages of simple structure, low cost, easy fabrication, reliable capability, and convenient maintenance.
Description
The utility model relates to a kind of device that prevents that electrical appliance is struck by lightning.
At present; the normally used device that is struck by lightning that prevents only is installed in the lightning arrester on the building; these lightning arresters can only protect building not broken by thunder and lightning; and can not prevent that the household electrical appliance in the building are struck by lightning; and generally all do not prevent the protective device that is struck by lightning on the existing household electrical appliance; therefore these household electrical appliance are easy to be broken by thunder and lightning, thereby cause unnecessary loss when thundery sky uses.
The purpose of this utility model is: provide a kind of simple in structure, cheap, can prevent the device that household electrical appliance are struck by lightning, to overcome the deficiencies in the prior art.
The utility model is to constitute like this: it comprises shell (1) and circuit board (2), circuit board (2) is contained in the shell (1), go up useful appliance wiring end (5) at shell (1), two blocks of sawtooth pattern discharge metal plates (3) are housed on circuit board (2), two fuse R1, R2, two inductance coil L1, L2, capacitor C and piezo-resistance R, the sawtooth of two blocks of sawtooth pattern discharge metal plates (3) point relatively and be separated with certain interval, wiring of input power source end (4) is arranged respectively on two blocks of sawtooth pattern discharge metal plates (3), two blocks of sawtooth pattern discharge metal plates (3) respectively with R1, R2 connects, R1, R2 respectively with L1, the end of L2 connects, L1, the other end of L2 with connect that C is connected with R and be connected with electrical appliance terminals (5).
Owing to adopted technique scheme, the utility model compared with prior art, have the function that can prevent that household electrical appliance from being broken by thunder and lightning when thundery sky uses, and the utility model also have simple in structure, cheap, make easily, dependable performance, advantage easy to maintenance.During use, earlier power line is fixed on the terminals (4), household electrical appliance are connected on the electrical appliance terminals (5), like this, household electrical appliance get final product normal electricity consumption, when thunderbolt takes place when, between the sawtooth point of two blocks of sawtooth pattern discharge metal plates (3), discharge, thereby thunderbolt intensity in the end is fallen, if be higher than the voltage of regulation by the voltage of fuse and inductance, then piezo-resistance conducting increases the electric current by fuse, thereby make the fuse quick-break, can reach like this and prevent the purpose of being struck by lightning.
Accompanying drawing 1 is a schematic appearance of the present utility model;
Accompanying drawing 2 is a structure principle chart of the present utility model.
Embodiment of the present utility model: shell (1) preferably adopts the higher insulating material of intensity to make, circuit board (2) adopts circuit board material commonly used in the prior art to make and gets final product, two fuse R1, R2, two inductance coil L1, L2, capacitor C and piezo-resistance R all adopt the finished product of selling on the market to assemble, two blocks of sawtooth pattern discharge metal plates (3) preferably adopt electric conductivity copper coin material preferably, on circuit board (2), load onto two blocks of sawtooth pattern discharge metal plates (3), and the sawtooth point that makes two blocks of sawtooth pattern discharge metal plates (3) relatively and be separated with certain interval, this gap generally is controlled between 0.1～1.2 millimeter, on two blocks of sawtooth pattern discharge metal plates (3), fix a last wiring of input power source end (4) respectively, with two blocks of sawtooth pattern discharge metal plates (3) respectively with R1, R2 one end connects, again with R1, the R2 other end respectively with L1, the end of L2 connects, with L1, the other end of L2 with meet C and be connected with R and be connected with electrical appliance terminals (5), electrical appliance terminals (5) can adopt socket commonly used or other wiring construction, circuit board (2) is contained in the shell (1), on shell (1), loads onto the electrical appliance terminals and (5).
Claims (1)
1, a kind of electrical appliance that prevents is by the device that is struck by lightning, it comprises shell (1), circuit board (2), circuit board (2) is contained in the shell (1), go up useful appliance wiring end (5) at shell (1), it is characterized in that: two blocks of sawtooth pattern discharge metal plates (3) are housed on circuit board (2), two fuse R1, R2, two inductance coil L1, L2, capacitor C and piezo-resistance R, the sawtooth of two blocks of sawtooth pattern discharge metal plates (3) point relatively and be separated with certain interval, wiring of input power source end (4) is arranged respectively on two blocks of sawtooth pattern discharge metal plates (3), two blocks of sawtooth pattern discharge metal plates (3) respectively with R1, R2 connects, R1, R2 respectively with L1, the end of L2 connects, L1, the other end of L2 with connect that C is connected with R and be connected with electrical appliance terminals (5).
