Technical field
The utility model relates to electrical distribution field, particularly relate to a kind of transmission line lightning stroke protection device.
Background technology
Transmission of electricity is after the electric energy sent by electromotor with transformator boosts, then controls equipment access power transmission line through chopper etc.
Road realizes.By version, transmission line of electricity is divided into overhead transmission line and cable run.Overhead transmission line route route lever
Tower, wire, insulator, line hardware, bracing wire, pole and tower foundation, grounding device etc. are constituted, and are erected on ground.
According to the character of conveying electric current, transmission of electricity is divided into ac transmission and direct current transportation.The eighties in 19th century is the most successfully
Achieve direct current transportation.But owing to the voltage of direct current transportation is difficult to continue to improve under technical conditions at that time, so that ability to transmit electricity
It is restricted with benefit.In 19 end of the centurys, direct current transportation is progressively replaced by ac transmission.The success of ac transmission, has welcome 20
The New Times of century electrification society.
Due to transmission line of electricity in the wild, can be shocked by electricity by thunder and lightning at any time, therefore can be made the high voltage of moment, high electricity
Stream punctures high-voltage electrical equipment along high-tension bus-bar with the speed of light, and the instantaneous pressure electric current after the most how thunder and lightning being hit draws
Enter underground and become the problem needing to solve.Accordingly, it would be desirable to design transmission line of electricity lightning proof, it is ensured that the electricity consumption peace of transmission line of electricity
Entirely.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of transmission line lightning stroke protection device, it is possible to by thunder and lightning
During produce instantaneous pressure electric current safety be incorporated into underground, and then ensure the Electrical Safety of transmission line of electricity.
In order to solve above-mentioned technical problem, the utility model proposes techniques below scheme: a kind of transmission line lightning stroke is protected
Device, it includes outer truss and interior anchor ear, and described outer truss and interior anchor ear constitute and seal cavity body structure, and described outer truss outer wall is solid
Dingan County is connected with gas cylinder equipped with intake valve and air bleeding valve, described intake valve, and the inwall of described outer truss is fixing connects fusing
Post, described fusing post is fixedly linked with drawing electricity seat, and described interior anchor ear is fixedly mounted on high-tension bus-bar outer surface, described interior anchor ear
Outer wall is fixedly connected with spine.
Described outer truss uses split type structure, is bolted to connection, between two pieces of outer trusses at its faying face
It is provided with insulated enclosure circle.
Described outer truss is fixedly linked with external ground line by cable.
Described gas cylinder internal dress sulfur hexafluoride.
Described spine, fusing post and the quantity drawing electricity seat are all four, are distributed on outer barrel wall and inner barrel wall.
This utility model has the advantages that:
By the principle according to point discharge, it is achieved that the thunder and lightning of moment is introduced underground, and fusing post can be cut in time simultaneously
The electric arc that pregnancy ceased is raw, it is achieved that safeguard the function of high-tension circuit.
Accompanying drawing explanation
The utility model is described in further detail with embodiment below in conjunction with the accompanying drawings.
Fig. 1 is this utility model sectional structure chart.
Fig. 2 is this utility model end face structure figure.
In figure: outer truss 1, insulated enclosure circle 11, intake valve 12, gas cylinder 13, air bleeding valve 14, fusing post 15, draw electricity
Seat 16, interior anchor ear 2, spine 21, high-tension bus-bar 3.
Detailed description of the invention
Below in conjunction with the accompanying drawings embodiment of the present utility model is described further.
Such as Fig. 1-2, a kind of transmission line lightning stroke protection device, it includes outer truss 1 and interior anchor ear 2, described outer truss 1 He
Interior anchor ear 2 constitutes sealing cavity body structure, and described outer truss 1 outer wall is installed with intake valve 12 and air bleeding valve 14, described air inlet
Valve 12 is connected with gas cylinder 13, the fixing fusing post 15 that connects of the inwall of described outer truss 1, described fusing post 15 and draw electricity seat 16
Being fixedly linked, described interior anchor ear 2 is fixedly mounted on high-tension bus-bar 3 outer surface, and the outer wall of described interior anchor ear 2 is fixedly connected with spine
21.By forming airtight space outside between truss 1 and interior anchor ear 2, it is possible to play the effect of insulation, by gas cylinder 13
Constantly to the internal insufflation gas of confined space, and then the effect of sealing can be played, point can be used by arranging spine 21
End discharge principle, it is achieved that the thunder and lightning of moment is introduced underground, can cut off the electric arc of generation in time, it is achieved that dimension by fusing post
Protect the function of high-tension circuit.
Further, described outer truss 1 uses split type structure, is bolted to connection between two pieces of outer trusses 1,
Insulated enclosure circle 11 it is provided with at its faying face.Good sealing function is played to sealing cavity by insulated enclosure circle 11.
Further, described outer truss 1 is fixedly linked with external ground line by cable.Electric current can be drawn by ground connection
Enter to underground, and then achieve the purpose of ground connection.
Further, described gas cylinder 13 internal dress sulfur hexafluoride.Use sulfur hexafluoride can play well insulation
Purpose, and it can under action of high voltage electricity
Further, described spine 21, fusing post 15 and the quantity drawing electricity seat 16 are all four, are distributed on outer barrel wall and interior
On bucket wall.Using fuses post 15 and draw electricity seat 16 can cut off the electric arc of generation easily, it is achieved that safeguard the merit of high-tension circuit
Energy.
Operation principle of the present utility model and work process be:
