Abstract
The utility model discloses a 5kV lightning protection protector of surging to the antithetical couplet is in the power consumption return circuit, including piezo -resistor MOV1, piezo -resistor MOV2, gas discharge tube FD1 and gas discharge tube FD2, the parallelly connected back termination N line of piezo -resistor MOV1 and piezo -resistor MOV2, another termination gas discharge tube FD1's one end, gas discharge tube FD1's the other end divides two the tunnel, connect the L line all the way, another way connects gas discharge tube FD2's one end, another termination G line of gas discharge tube FD2, simple structure of the circuit, easy installation, high reliability, circuit design is reasonable, fully considered between the looks (line) because the possibility that the surge that various couplings arouse constantly appears, possess looks (line) to ground and looks, protect function between the line, satisfy the requirement of differential mode and common mode protection simultaneously.
Description
Technical field
This utility model is related to a kind of electric equipment protection device, and particularly a kind of 5kV lightning protection is surged protector.
Background technology
Street lamp install out of doors, thunderbolt is a very big threat, gently then lead to street lamp damage, heavy then cause fire or
Casualties, produces huge loss, accordingly, it would be desirable to install lightning protection to street lamp surge protector.Anti- lightning surge of the prior art
Unrestrained protector is connected with street lamp, and electronic devices and components are more, and circuit is complicated, lightning protection rank deficient, and production cost is high, installs
More bother.
Content of the invention
In order to overcome the deficiencies in the prior art, this utility model provides one kind to possess phase（Line）Over the ground and between phase, line
Defencive function, meets differential mode simultaneously and 5kV lightning protection that common mode protection requires is surged protector.
This utility model solves its technical problem and be employed technical scheme comprise that：
A kind of 5kV lightning protection is surged protector, is connected in parallel on in The electric loop, including varistor MOV1, varistor MOV2,
A termination N line after gas-discharge tube FD1 and gas-discharge tube FD2, described varistor MOV1 and varistor MOV2 parallel connection, separately
One end of the one described gas-discharge tube FD1 of termination, the other end of described gas-discharge tube FD1 divides two-way, and a road connects L line, another
Road connects one end of described gas-discharge tube FD2, another termination G line of described gas-discharge tube FD2.
It is serially connected with protective tube F1 in the described line meeting L line and gas-discharge tube FD1.
The beneficial effects of the utility model are：Lightning protection of the present utility model protector of surging is connected in parallel on in The electric loop, by
Two varistors, two gas-discharge tubes and a protective tube are constituted, and circuit structure is simple, easy for installation, and reliability is high, electricity
Road is reasonable in design, has taken into full account phase（Line）Between the possibility that continuously emerges of the surge that caused due to various couplings, possess phase
（Line）Defencive function over the ground and between phase, line, meets differential mode and the requirement of common mode protection simultaneously.
Brief description
With reference to the accompanying drawings and examples this utility model is further illustrated.
Fig. 1 is circuit theory diagrams of the present utility model；
Fig. 2 is use state of the present utility model with reference to figure.
Specific embodiment
With reference to Fig. 1, Fig. 2, a kind of 5kV lightning protection is surged protector, is connected in parallel on in The electric loop, including varistor MOV1,
Varistor MOV2, gas-discharge tube FD1 and gas-discharge tube FD2, described varistor MOV1 and varistor MOV2 are in parallel
A termination N line N afterwards（Zero line）, one end of the described gas-discharge tube FD1 of another termination, the other end of described gas-discharge tube FD1
Divide two-way, a road connects L line（Live wire）, another road connects one end of described gas-discharge tube FD2, and described gas-discharge tube FD2's is another
One termination G line（Ground wire）, in the described line meeting L line and gas-discharge tube FD1, it is serially connected with protective tube F1.Circuit structure is simple,
Easy for installation, reliability is high, and circuit design rationally, has taken into full account phase（Line）Between the surge that caused due to various couplings continuous
The possibility occurring, possesses phase（Line）Defencive function over the ground and between phase, line, meets differential mode and the requirement of common mode protection simultaneously.
It is 300V that described protective tube F1 adopts rated voltage, and rated current is the square protective tube of 5A, described protective tube F1
Play self-protection effect；The rear end of described shell is provided with the fixing hole of a band closure, as long as a screw just can be fixed；Institute
State varistor MOV1 and varistor MOV2 and adopt 331KD14 varistor；Described gas-discharge tube FD1 and gas-discharge tube
FD2 adopts LT-B8G600L gas-discharge tube.
When circuit voltage is higher than that varistor MOV1 and varistor MOV2 start voltage, varistor MOV1 and pressure-sensitive
The resistance of resistance MOV2 drops to rapidly zero, in channel status, forms electric discharge with gas-discharge tube FD1 and gas-discharge tube FD2
Passage, discharges high pressure；When circuit voltage is less than varistor MOV1 and varistor MOV2 and starts voltage, varistor MOV1
Resistance with varistor MOV2 is infinity, in off state, completely cuts off completely with circuit, only with 5 electronic devices and components just
Higher lightning protection grade can be reached.
Above embodiment can not limit the protection domain of the invention, the personnel of professional skill field without departing from
In the case of the invention general idea, impartial modification and the change done, all still fall within the scope that the invention is covered
Within.
