To achieve these goals, present invention employs following technical scheme：
A kind of separate assembling compresses arc-extinguishing tube, including arc part is led in arc-extinguishing tube main body and centre；Described arc-extinguishing tube main body is by a left side
Semicanal and right semicanal composition；The bore at described left semicanal both ends is the same and the diameter of arc part is led less than centre, left semicanal
Pipe external diameter is less than or equal to the diameter that arc part is led in centre；One end bore of described right semicanal and the bore one of left semicanal
Sample, other end bore are more than or equal to the diameter that arc part is led in centre；After centre is led arc part be put into right semicanal, left semicanal
Embedded right semicanal, leads arc part by centre and is fixed in arc-extinguishing tube main body.
Arc-extinguishing tube main body is made up of two parts in the present invention, and to left semicanal, right semicanal, the middle caliber for leading arc part or
Diameter makes corresponding limitation, and centre can be led to arc part and be fixed on arc-extinguishing tube body interior, ensure among lead arc part will not be by
Outside air blast discharge pipe so that compression arc-extinguishing tube, which loses, leads arc effect.
The present invention further illustrates, described left semicanal with set together with the direct nested encryptions of right semicanal or respectively in
Use and be threaded togather after external screw thread.
The present invention further illustrates that the outer surface of described left semicanal is provided with spacing disk.Spacing disk can be to right half
Pipe carry out it is spacing, will the connecting length of left semicanal and right semicanal be defined.

For pipe in the arc extinguishing passage being placed in lightning protection device device, shirt rim can not only play a part of fixed compression arc-extinguishing tube, may be used also
Effectively to prevent electric arc along the compression direct flashover of arc extinguishing tube outer surface.
The present invention further illustrates that described centre leads arc part and leads arc part for ball either disk with holes leads arc part or double
Face circular cone leads arc part or two-sided nail leads arc part.Arc part is led in centre sharp end points, makes it have superpower striking and makees
With, ensure that electric arc is attracted, into inside compression arc-extinguishing tube, the flashover in specified arc extinguishing path.
In the present invention, the middle material for leading arc part is graphite or metal.
The operation principle of the present invention：
First stage（Compress temperature-rise effect）
When being struck by lightning, electric arc can be drawn into arc extinguishing path by arc electrode, on the one hand, arc extinguishing path can draw electric arc
Long, on the other hand, arc-extinguishing tube is made of heat-barrier material, and electric arc is formed greatly in very short time with the cold passage inwall of arc-extinguishing tube
Contact area, arc column periphery cool down immediately, and arc column radius reduces.The reduction of arc column radius both can be outside intake line a large amount of gases
Self-resistance can be increased again, and then cause arc column central temperature to steeply rise.
Second stage（Temperature rise directional explosion arc extinguishing effect）
Because heat transfer temperature can be raised quickly, volume will increase rapidly the gas being inhaled into, by the pressure of inner-walls of duct, footpath
Axial self-expanding air-flow is developed into self-expanding air-flow, and this axial self-expanding air-flow can be by the fragile electric arc of elongation from arc-extinguishing tube
Mediad pipe ends longitudinally blow out, at the port of arc-extinguishing tube, electric arc is developed to free state, direct edge from extreme squeezed state
Eject pipeline in arc motion direction（Vertical to blow, electric arc is elongated longitudinally, weakened）.By being blown in whole the vertical of arc extinguishing path, electricity
By constantly longitudinally elongated, the energy for concentrating on arc column axle center originally is discharged and developed to outside pipeline with the situation sprayed arc, is gone out
Arc energy in arc path is gradually reduced, and is finally grounded in arc extinguishing path ends.
Phase III（Electric arc self-gravitation effect, line mutual-ground capacitor suppress arc reignition principle）
The little energy of initial arc storage, electric arc is once truncated in second stage there are micro-fractures, and this fracture can be rapid
Full gap is extended to, the avalanche effect for electric arc opening occur, arc plasma, which is known from experience, to be buried in oblivion rapidly, is converted into state of insulation；
After generation fracture, compression pipe arc extinguishing destroys thunder and lightning arc, and capacitance voltage is equivalent to electric arc fracture is connected in parallel on, so that work
Frequency afterflow does not have path to flow through insulator, can only be discharged by direct-to-ground capacitance, and capacitance voltage can not be mutated, so the work of electric arc
Frequency voltage is from almost nil slowly rising is started, so the possibility restriked in the absence of micro-fractures by power-frequency voltage flashover.
Advantages of the present invention：
1. simple in construction, reasonable in design, arc extinguishing ability is strong, and work is more reliable and more stable.Installed in the interposition of compression arc-extinguishing tube
Put centre and lead arc part, and centre leads arc part and has sharp end points, makes it have superpower striking effect, ensures that electric arc is inhaled
Draw, into inside compression arc-extinguishing tube, the flashover in specified arc extinguishing path.Arc-extinguishing tube main body is made up of two parts, and to a left side
Semicanal, right semicanal, the caliber of arc part is led in centre or diameter makes corresponding limitation, and centre can be led to arc part and be fixed on arc-extinguishing tube
Body interior, ensure among lead arc part will not be by air blast discharge pipe outside so that compression arc-extinguishing tube lose leads arc effect.
2. full gaseous state passage.Other arc quenching principles are required for arc quenching material, there is spillage of material；For example, baking arc extinguishing passes through
Toast gas exhausted material and produce air-flow arc extinguishing, gas exhausted material needs to be lost.And the arc extinguishing energy source of this arc quenching principle is impact electric arc,
By certain structure, using impacting the energy of electric arc itself come arc extinguishing, it is not necessary to other materials, noenergy loss.
3. shirt rim is provided with the present invention；When compression arc-extinguishing tube is placed on into the arc extinguishing passage in lightning protection device device, shirt rim is not
