Abstract
The utility model discloses a street lamp lightning stroke resistance insurance device. The device comprises a power supply and an insurance circuit which is connected to the power supply. The insurance circuit comprises a first branch and a second branch which are arranged in parallel. The first branch is provided with a street lamp working circuit and a first fuse which are connected in series. The second branch is provided with a lightning stroke resistance device and a second fuse which are connected in series. According to the lightning stroke resistance insurance device, the first fuse and the second fuse are connected in parallel so that the street lamp working circuit can work normally when lightning stroke is generated, which brings convenience for pedestrians. Simultaneously, maintenance frequencies of the street lamp can be reduced and cost is reduced too.
Description
Technical field
The utility model relates to a kind of safeties, relates in particular to a kind of anti-lightning safeties.
Background technology
Between charged cloud layer and the cloud layer with xenogenesis electric charge or charged cloud layer to the earth, swift and violent electric discharge can form thunder-strike phenomenon.This swift and violent discharge process produces strong lightning and follows huge sound, Here it is our lightning of seeing and thunderous.
It is even larger that lightning current is on average about 20000A(), lightning voltage is approximately 10 10 power volts, and the time of a thunder and lightning is approximately signa, and the power that an average thunder and lightning sends reaches 20,000,000,000 kilowatts.Electric discharge between cloud layer mainly has harm to aircraft, and the electric discharge of cloud layer to the earth is very large to building, electronic electric equipment and people, animal harm.Street lamp is at outside work, and therefore thunderstruck probability is higher, installs anti-lightning device and fuse additional at present street lamp operating circuit, is the effective ways that improve street lamp anti-lightning.When thunderbolt, anti-lightning device absorbs a large amount of electric currents, when this large electric current passes through fuse, by blown fuse, thereby has stoped large electric current to flow into street lamp operating circuit, and then has protected street lamp operating circuit.But, because the fuse of fusing disconnects whole circuit, street lamp operating circuit cannot be worked on, cause street lamp to extinguish, bring potential safety hazard to pedestrian.
In view of above problem, be necessary to provide a kind of new anti-lightning safeties, to solve the problems of the technologies described above.
Utility model content
For the deficiencies in the prior art, the technical problem that the utility model solves is to provide a kind of anti-lightning safeties, these anti-lightning safeties include the first fuse and the second fuse that are arranged in parallel, while making to be struck by lightning, the operating circuit of street lamp can normally be worked, bring convenience to pedestrian, the maintenance frequency that also can reduce street lamp simultaneously, has reduced cost.
For addressing the above problem, the technical solution of the utility model is achieved in that
A kind of anti-lightning safeties, the insurance circuit that comprises power supply and be connected with described power supply, described insurance circuit includes the first and second branch roads that are arranged in parallel, described the first branch road is provided with street lamp operating circuit and the first fuse that series connection arranges, and described the second branch road is provided with anti-lightning device and the second fuse that series connection arranges.
Further, described insurance circuit also can be arranged in parallel three insurance circuit identical with described the second branch structure.
Further, the protective current of described the second fuse is greater than the protective current of described the first fuse.
Further, described power supply includes live wire, zero line and ground wire, described the first branch road and electric power generating composition the first loop, live wire in described the first loop is connected with described the first fuse, described zero line is connected with described street lamp operating circuit, described the second branch road and electric power generating composition second servo loop, and the live wire in described second servo loop is connected with described the second fuse, described zero line is connected with described anti-lightning device, and described anti-lightning device is also connected with described ground wire.
The beneficial effects of the utility model are: compared to prior art, anti-lightning safeties of the present utility model include the first fuse and the second fuse that are arranged in parallel, while making to be struck by lightning, the operating circuit of street lamp can normally be worked, bring convenience to pedestrian, the maintenance frequency that also can reduce street lamp simultaneously, has reduced cost.
Accompanying drawing explanation
Fig. 1 is the circuit diagram of the utility model anti-lightning safeties.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, be described in greater detail below in conjunction with the drawings and specific embodiments.
Refer to shown in Fig. 1 anti-lightning safeties of the present utility model, the insurance circuit 200 that comprises power supply 100 and be connected with described power supply 100.Described power supply 100 includes live wire 110, zero line 120 and the ground wire 130 in 220V circuit.Described insurance circuit 200 includes the first branch road 210 and the second branch road 220 that are arranged in parallel, described the first branch road 210 is provided with street lamp operating circuit 211 and the first fuse 212 that series connection arranges, and described the second branch road 220 is provided with anti-lightning device 221 and the second fuse 222 that series connection arranges.In other embodiments, described insurance circuit 200 also can be arranged in parallel three insurance circuit (not shown) identical with described the second branch road 220 structures.
In the loop forming at described the first branch road 210 and power supply 100, described live wire 110 is connected with described the first fuse 212, and described zero line 120 is connected with described street lamp operating circuit 211.Described the first fuse 212 is protected the street lamp operating circuit 211 in above-mentioned loop, in the time that street lamp operating circuit 211 is abnormal described in the first fuse 212 fusible, and then protect whole loop.In the loop forming at described the second branch road 220 and power supply 100, described live wire 110 is connected with described the second fuse 222, and described zero line 120 is connected with described anti-lightning device 221, and described anti-lightning device 221 is also connected with described ground wire 130.The specification of described the first fuse 212 is 2A ~ 10A, and the specification of described the second fuse 222 is 10A ~ 40A, and the protective current of described the second fuse 222 is greater than the protective current of described the first fuse 212.
When thunderbolt, described anti-lightning device 221 absorbs a large amount of thunder-strike currents, described in this current direction when the second fuse 222, if electric current is less than the maximum protection electric current of described the second fuse 222, the first branch road 210 and the second branch road 220 are all normally worked, and street lamp does not extinguish; If electric current is greater than the maximum protection electric current of described the second fuse 222; described the second fuse 222 fuses, thereby stops large electric current to flow into described the first branch road 210, and then the first protective circuit 210 can normally be worked; street lamp can keep the state not extinguishing, and has brought convenience to traffic.
Compared to prior art, the utility model anti-lightning safeties are owing to being arranged in parallel the first fuse 212 and the second fuse 222, while making to be struck by lightning, the street lamp operating circuit 211 of street lamp can normally be worked, bring convenience to pedestrian, the maintenance frequency that also can reduce street lamp simultaneously, has reduced cost.
Of particular note, for those skilled in the art, that under guiding of the present utility model, has done changes for equivalence of the present utility model, must be included in the leading scope of the utility model claim.
