The recoil that electric arc enters " V " type structure after the weakening of L-type arc extinguishing component 5 accelerates arc extinguishing component 4 to carry out one A weakening.It is to carry out recoil to liquidate that each recoil, which accelerates arc extinguishing component 4, then by accelerating to spray, is formed each anti- It is all the effect of second level arc extinguishing that punching, which accelerates arc extinguishing component 4,.V-type arc extinguishing recoil tube 4.1A and V-type arc extinguishing acceleration jet pipe 4.3A are It is set as straight tube structure, is liquidated so that carrying out recoil in V-type arc extinguishing recoil tube 4.1A, specific back flushing process enters shown in Figure 10.

As seen in figs. 5-6, recoil accelerates arc extinguishing component 4 to connect sudden strain of a muscle including combined arc extinguishing recoil tube 4.1B, combined arc extinguishing Electrode 4.2B, combined arc extinguishing accelerate jet pipe 4.3B, combined arc extinguishing recoil tube arc electrode 4.4B, combined arc extinguishing to accelerate spray Pipe arc electrode 4.5B, the combined arc extinguishing recoil tube 4.1B accelerate jet pipe 4.3B to be connected to combined arc extinguishing, and combined Arc extinguishing connects the connection that lightning pole 4.2B is sealingly disposed in combined arc extinguishing recoil tube 4.1B and combined arc extinguishing accelerates jet pipe 4.3B Place, the combined arc extinguishing recoil tube 4.1B are set as straight tube structure, and combined arc extinguishing recoil tube 4.1B and recoil spout 3 connect It is logical, and combined arc extinguishing recoil tube arc electrode 4.4B is arranged in recoil spout 3, combined arc extinguishing recoil tube arc electrode 4.4B accelerates arc extinguishing component 4 or L-type arc extinguishing component 5 to connect by connecting line 7 with previous recoil, and the combined arc extinguishing adds Fast jet pipe 4.3B is set as curved pipe, and combined arc extinguishing accelerates jet pipe 4.3B to be connected to spout 2 is accelerated, and combined arc extinguishing accelerates Jet pipe arc electrode 4.5B setting is accelerating in spout 2, accelerates arc extinguishing component 4 to connect with next recoil by connecting line 7.

The recoil arc extinguishing process of combined arc extinguishing recoil tube 4.1B and the recoil of V-type arc extinguishing recoil tube 4.1A liquidate arc extinguishing Process is identical.Combined arc extinguishing accelerates jet pipe 4.3B to be set as arcuate structure, so that electric arc more squeezes in curved pipe with side wall Pressure and collision, so that temperature increases faster, the blowing force of the ejiction opening of generation is bigger.

As Figure 7-8, recoil accelerates arc extinguishing component 4 to connect lightning pole including U-shaped arc extinguishing recoil tube 4.1C, U-shaped arc extinguishing 4.2C, U-shaped arc extinguishing accelerate jet pipe 4.3C, U-shaped arc extinguishing recoil tube arc electrode 4.4C and U-shaped arc extinguishing to accelerate jet pipe arc electrode 4.5C, U-shaped arc extinguishing recoil tube 4.1C accelerate jet pipe 4.3C to be connected to composition U-typed structure with U-shaped arc extinguishing, and U-typed structural openings refer to To the outside of sub-pieces ontology 1, the U-shaped arc extinguishing meets lightning pole 4.2C and is sealingly disposed in U-shaped arc extinguishing recoil tube 4.1C and U-shaped Arc extinguishing accelerates the junction of jet pipe 4.3C, U-shaped arc extinguishing recoil tube 4.1C and U-shaped arc extinguishing recoil tube arc electrode 4.4C recoil spray Mouth (3) connection, and U-shaped arc extinguishing recoil tube arc electrode 4.4C is arranged in recoil spout 3, U-shaped arc extinguishing recoil tube arc electrode 4.4C accelerates arc extinguishing component 4 or L-type arc extinguishing component 5 to connect by connecting line 7 with previous recoil, and the U-shaped arc extinguishing accelerates Jet pipe 4.3C is set as half U-typed pipe, and U-shaped arc extinguishing accelerates jet pipe 4.3C to be connected to spout 2 is accelerated, and U-shaped arc extinguishing accelerates jet pipe Arc electrode 4.5C setting is accelerating in spout 2, accelerates arc extinguishing component 4 to connect with next recoil by connecting line 7.

U-shaped arc extinguishing recoil tube 4.1C and U-shaped arc extinguishing accelerate jet pipe 4.3C to be arranged to half " U " structure, then are then to be Arcuate structure, so that electric arc is when entering, the number of friction and collision between side wall is more, and temperature increases faster accumulation More energy, the more fierceness so that the recoil formed in U-shaped arc extinguishing recoil tube 4.1C liquidates accelerate to spray in U-shaped arc extinguishing Carry out recoiling the speed to liquidate in pipe 4.3C faster, the effect of arc extinguishing is more preferable.

As shown in Figure 10, in the application, can define outer electric arc in inlet speed is v0, and pressure p0, density is ρ 0, temperature Degree is T0.After outer electric arc enters recoil component, the entrance arc speed v1 of formation, pressure p1, density is ρ 1, temperature T1. Arc speed v2, pressure p2 are exported after striking component, density is ρ 2, temperature T2.Outer electric arc is entered anti-by entrance It rushes component and forms interior electric arc, interior electric arc is limited by recoil component walls, and diameter is by large scale mechanical compression, so that interior electric arc Temperature, density, pressure and speed rise.Arc energy loss and rubbing action are not considered, when entrance electric arc is through overcompression electricity Realize elastic collision moment in pole, it is believed that v1=-v2, i.e. entrance arc speed size and muzzle velocity are equal in magnitude, contrary. Consider arc energy loss and rubbing action, entrance electric arc is after compression electrodes are collided, Ren Wei ∣ v2 ∣ < ∣ v1 ∣, i.e. outlet speed It is smaller than entrance velocity to spend size, it is contrary.Inhibition of the electric arc by entrance electric arc is exported, outlet arc diameter compares entrance Arc diameter is small, keeps the density, temperature and pressure that export electric arc bigger than entrance electric arc, i.e. 2 > ρ 1 of ρ, T2 > T1, p2 > P1, these collective effects make v2 speedup be greater than v1 speedup, i.e. a2 > a1.As outlet arc diameter is constantly compressed, make to obtain Mouth arc density, temperature and pressure constantly increase, and ultimately form v2 > v1, and outlet electric arc is promoted to go out recoil group from inlet Part.After outlet electric arc is to go out recoil component, external electric arc forms cavity effect, destroys electric arc continuity, weakens arc energy, It is accelerated to be truncated and extinguish.

The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention, for this field skill For art personnel, it is clear that invention is not limited to the details of the above exemplary embodiments, and without departing substantially from spirit of the invention or In the case where essential characteristic, the present invention can be realized in other specific forms.Therefore, in all respects, should all incite somebody to action Embodiment regards exemplary as, and is non-limiting, the scope of the present invention by appended claims rather than on state Bright restriction, it is intended that including all changes that fall within the meaning and scope of the equivalent elements of the claims in the present invention It is interior.Any reference signs in the claims should not be construed as limiting the involved claims.
