Example 5:
the secondary backflushing device comprises a secondary backflushing pipe 9 and a secondary lightning receiving electrode 10, the secondary backflushing pipe 9 is of a hollow tubular structure, the secondary lightning receiving electrode 10 is arranged at the bottom end of the inside of the secondary backflushing pipe 9 in a sealing mode, and a backflushing nozzle 11 is arranged on the side wall of the secondary backflushing pipe 9. The backflushing nozzle 11 is provided with a backflushing nozzle sealing cover 12, the backflushing nozzle sealing cover 12 covers the backflushing nozzle 11 and can be arranged in a lifting mode, and the backflushing nozzle sealing cover 12 can be movably arranged at the top end of the backflushing nozzle 11 through a rotating point 13.
And the residual electric arc on the primary recoil device is transmitted into the first secondary recoil device from the lightning receiving electrode, and then is transmitted into the second secondary recoil device after being recoiled, so that the electric arc is gradually extinguished, and the electric arc is extinguished. The electric arc is compressed in the secondary recoil pipe 9, then when the pressure intensity is larger than the lateral gravity of the recoil nozzle sealing cover 12, the recoil nozzle sealing cover 12 is lifted upwards, and then high-pressure gas is sprayed out from the recoil nozzle 11, so that the effect of pressurizing and recoiling the electric arc is realized.
The primary lightning receiving electrode 2 and the secondary lightning receiving electrode 10 are of metal structures, the shapes of the metal structures are the same as the hollow pipe structures in the primary recoil pipe 1, and the side wall of the primary recoil pipe 1 and the side wall of the secondary recoil pipe 9 are made of high-strength high-temperature-resistant high-pressure-resistant non-conductive materials. The arc striking component is arranged to be a conductive metal ring, the outer side wall of the conductive metal ring is tightly attached to the inner wall of the primary recoil pipe, and the lightning receiving component is made of a conductive material. The high-strength high-temperature-resistant high-pressure-resistant non-conductive material is any one of alloy ceramic, rare earth ceramic, graphene-ceramic composite material, organic ceramic, synthetic silicone rubber, organic insulating material, alloy glass, rare earth glass, graphene glass and organic glass.
As shown in FIG. 6, the outer arc may be defined to have a velocity at the inlet v0, a pressure p0, a density ρ 0, and a temperature T0. After the outer arc enters the recoil assembly, an inlet arc velocity v1, a pressure p1, a density ρ 1 and a temperature T1 are formed. After passing through the arc striking assembly, the outlet arc speed v2 is p2, the pressure is p2, and the temperature is T2. The outer arc enters the recoil assembly through the inlet to form an inner arc, the inner arc is limited by the recoil assembly wall, the diameter is mechanically compressed by a large scale, and the temperature, the density, the pressure and the speed of the inner arc are all increased. Regardless of the arc energy loss and friction effects, when the inlet arc passes through the lightning strike assembly to achieve a resilient impact moment, v1 is considered to be-v 2, i.e., the inlet arc velocity is equal in magnitude and opposite in direction to the outlet velocity. Considering the energy loss and friction of the arc, after the inlet arc collides with the lightning receiving assembly, it is considered that | v2 | v1 | that the outlet velocity is smaller than the inlet velocity and the direction is opposite. The outlet arc is impeded by the inlet arc, which is smaller in diameter than the inlet arc, so that the outlet arc has a greater density, temperature and pressure than the inlet arc, i.e. ρ 2 > ρ 1, T2 > T1, p2 > p1, which in combination accelerate v2 more than v1, i.e. a2 > a 1. As the outlet arc diameter is increasingly compressed, resulting in an increase in outlet arc density, temperature and pressure, v2 > v1 eventually causes the outlet arc to rush out of the recoil assembly from the inlet. After the electric arc at the outlet rushes out of the recoil component, a cavity effect is formed on the external electric arc, the continuity of the electric arc is damaged, the energy of the electric arc is weakened, and the cutting and extinguishing of the electric arc are accelerated.
Considering that air exists in the recoil assembly, after the electric arc enters the recoil assembly, a series of effects and mechanisms are formed, so that the air in the recoil assembly is compressed, the air pressure in the recoil assembly is increased, the free stroke length of the electron is reduced, the ionization process is weakened and inhibited, the electric insulation strength is obviously improved, and the electric arc is favorably cut off and extinguished. According to experimental data, when air is compressed from 0.1Mpa (1atm) to 2.8Mpa, the breakdown voltage of the compressed air can be increased to 9-12 times of the standard air breakdown voltage (30kV/cm), and the electrical insulation strength is greatly improved. The original air in the recoil component is influenced by the temperature rise effect and the pressure rise effect in the recoil component, the generated jet air flow is jetted from the recoil component and acts on the outer electric arc, and the convection, radiation and conduction of the outer electric arc are accelerated by utilizing the cavity effect of the air flow on the outer electric arc, so that the electric arc is converted into dielectric property from electric conductivity, and the electric arc is self-extinguished.
As shown in fig. 7, when a lightning flashover arc approaches the structure of the present application, the arc striking electrode forms an upward path by physical touch, coulomb force action or point discharge to the flashover arc, and draws the arc to the vicinity of the inlet of the first primary recoil pipe, and the outer arc enters the ultrafine primary recoil pipe under the drawing of the arc striking component of the first primary recoil pipe, wherein the inner diameter of the primary recoil pipe is much smaller than the diameter of the arc, the arc column is filled by the narrow pipe in the primary recoil pipe, the arc is limited by the pipe wall of the recoil unit, the diameter of the arc column is forcibly reduced, the conductive cross-sectional area of the whole arc is reduced, and the arc resistance is increased, according to the power calculation formula: p ═ I2R, the electric arc power is increased, so that the heat and the temperature in the tube are increased, which is power temperature rise, meanwhile, 180-degree opposite impact collision is generated between the inlet electric arc and the outlet electric arc in the tube, a channel for arc radiation, convection, conduction and loss is cut off, heat dissipation is blocked, the temperature is further increased, which is blocking temperature rise, the density of the electric arc plasma in the tube is sharply increased, the friction and the collision among particles are accelerated, the heat and the temperature are increased again, which is frictional temperature rise, the temperature difference between the inside and the outside of the tube is increased and the pressure difference is increased due to the three temperature rise effects, when the pressure in the primary recoil tube is larger than the pressure outside of the tube, a directional electric arc pressure explosion effect from inside to outside is generated, the electric arc in the tube is rapidly evacuated, the cavity effect of the outer electric arc is achieved, the injection of the energy of the outer electric arc is blocked, the residual electric arc is sequentially subjected to lightning connection, is guided by a next arc ignition assembly 1, and finally, the electric arc is simultaneously broken at a plurality of break points, the continuity of the electric arc is damaged, the extinguishing of the impact electric arc is accelerated, and the formation of a power frequency arc establishing channel is eliminated.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of the present invention, and these improvements and modifications should also be construed as the protection scope of the present invention.
