Lightning arrester body contains: base, its cover are put and are served under the insulator, the insulating tube, its one end and base link to each other, and in the insulating tube in proper order the interval be provided with a plurality of cavity electrode and a plurality of explosion chamber, the fumarole has been seted up corresponding to every explosion chamber top. The utility model discloses utilize high velocity gas to blow the outage arc to the reliable of electric power system transmission line and safety are guaranteed to effectual cutting off because of the discharge arc that the circuit overvoltage arouses, through operation indicator, indicating line passes by the pressure simultaneously.
Description
Technical field
This utility model relates to electric power facility Element Technology field, particularly to a kind of lightning protection device.
Background technology
Overhead distribution is installed series gap spark gap, it is possible to be struck by lightning or overvoltage and the protection insulator chain calcination from electrical discharge arc of effectively releasing during insulator chain flashover at circuit.Normal tape arrester with series gaps can effectively attract the overvoltage on circuit, punctures the air gap, and overvoltage is imported the earth.But, it does not possess actively arc extinguishing ability, it is impossible to the power frequency continued flow electric arc that automatic distinguishing causes because puncturing the air gap, only with auto recloser with the use of, preferable lightning protection effect could be obtained.But, owing to needs wait breaker actuation, cause the arc extinction time on series gap longer, the overvoltage on circuit be released to the earth every time, gold utensil all may be made by flash burn, when situation is serious, even can blow wire.
Utility model content
The purpose of this utility model is to provide a kind of lightning protection device, utilizes high-speed gas to blow electric arc, effectively to cut off the electrical discharge arc caused because of line over-voltage, it is ensured that the reliable and safety of power system transmission line, simultaneously by flag indicator, indicates Line over-voltage.
In order to realize object above, this utility model is achieved through the following technical solutions:
A kind of lightning protection device, is characterized in, comprises:
Insulator, is used for holding overhead transmission line；
Lightning arrester body, it is arranged on the insulator；
After the voltage of overhead transmission line is higher than threshold value, punctures the air gap and turn on lightning arrester body, discharging overvoltage energy.
Described lightning arrester body comprises:
Base, it is nested with on insulator lower end；
Insulation tube, its one end is connected with described base, and is sequentially arranged at intervals with several chamber electrodes and multiple arc-chutes in described insulation tube；Fumarole is offered corresponding to each arc-chutes top.
The other end of described insulation tube is provided with low-field electrode.
Described insulation tube is silicone rubber tube.
This device also comprises flag indicator, and it is connected on overhead transmission line by wire clamp, and forms discharging gap with described low-field electrode, is used for indicating overhead transmission line overvoltage.
This utility model compared with prior art, has the advantage that
1, simple installation, it is not necessary to ground connection, saves wire and installation cost.
2, indirect protection oxidized metal spark gap and transformator can bear the direct lightning strike of long period; persistency is good, and does not has long electric stress can reduce the size of electricity tower, and low-maintenance (is often only and is needed a visual examination); it is required for shielding line, there is high reliability and life-span.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of lightning protection device of this utility model；
Fig. 2 is the structural representation of a kind of lightning arrester body of this utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, by describing a preferably specific embodiment in detail, this utility model is further elaborated.
As it is shown in figure 1, a kind of lightning protection device, comprise: insulator 1, be used for holding overhead transmission line 2；Lightning arrester body 3, it is arranged on insulator 1；After the voltage of overhead transmission line 2 is higher than threshold value, punctures the air gap and turn on lightning arrester body 3, discharging overvoltage energy.
As in figure 2 it is shown, above-mentioned lightning arrester body 3 comprises: base 31, it is nested with on insulator 1 lower end；Insulation tube 32, its one end is connected with described base 32, and is sequentially arranged at intervals with several chamber electrodes 321 and multiple arc-chutes 322 in described insulation tube 32；Offering fumarole 323 corresponding to each arc-chutes 322 top, this fumarole 323 is for the injection of high-speed gas.The other end of insulation tube 32 is provided with low-field electrode 324.
In specific embodiment, above-mentioned insulation tube 32 is silicone rubber tube.
This lightning protection device also comprises flag indicator 4, it is connected on overhead transmission line 2 by wire clamp 5, and form discharging gap with low-field electrode 324, during work, overhead transmission line 2 overvoltage produce arc through discharging gap and connect flag indicator 4, the shell making flag indicator 4 is breakdown, plays the effect (instruction overhead transmission line overvoltage) of action instruction.
Overhead transmission line 2 can produce overvoltage ripple such as experience thunderbolt etc. during user's normal transmission.The air gap will be punctured after overvoltage is higher than threshold value, thus turn on overhead transmission line 2 and the lightning arrester body 3 being installed on insulator 1 so that it is complete that overvoltage energy will transfer electric arc release to, and voltage is reverted to normal value.Electric arc is caused in the arc-chutes 322 of lightning protection device by this lightning protection device by the low-field electrode 324 on top, high temperature is produced by the electric discharge of arc-chutes 322 middle chamber electrode 321, adding hot-air, release high-speed gas, by arc cutting, completes the function of the automatic arc extinguishing of lightning protection device.
In sum, this utility model one lightning protection device, utilize high-speed gas to blow electric arc, effectively to cut off the electrical discharge arc caused because of line over-voltage, it is ensured that the reliable and safety of power system transmission line, simultaneously by flag indicator, indicate Line over-voltage.
Although content of the present utility model has been made to be discussed in detail by above preferred embodiment, but it should be appreciated that the description above is not considered as restriction of the present utility model.After those skilled in the art have read foregoing, multiple amendment of the present utility model and replacement all be will be apparent from.Therefore, protection domain of the present utility model should be limited to the appended claims.
