The arc extinguishing process of the device:
when a lightning stroke flashover electric arc approaches to the backflushing device, the electric arc is drawn to the position close to the inlet of the first backflushing pipe by the arc-striking electrode, the outer electric arc enters the superfine backflushing pipe under the drawing of the arc-striking module of the first backflushing pipe, and the inner diameter of the backflushing pipe is far smaller than the diameter of the electric arc. The arc column is filled by the narrow pipe in the recoil pipe, the arc is limited by the pipe wall in the recoil module, the diameter of the arc column is forcibly reduced, so that the conductive cross-sectional area of the whole arc is reduced, the arc resistance is increased, and the power calculation formula is adopted: p ═ I2R indicates that the arc power also increases, and the heat and temperature in the tube increase, which is a power-dependent temperature rise. Meanwhile, the inlet electric arc and the outlet electric arc generate 180-degree opposite impact collision in the tube, so that a channel for arc radiation, convection, conduction and loss is cut off, heat dissipation is blocked, the temperature is further increased, and blocking temperature rise is realized. At the same time, the density of the arc plasma in the tube increases sharply, the friction and collision between particles are accelerated, and the heat and temperature rise again, which is a frictional temperature rise. The three temperature rise effects make the temperature difference between the inside and the outside of the pipe larger, resulting in the pressure difference also being larger. When the pressure in the recoil pipe is higher than the pressure outside the recoil pipe, the directional arc explosion effect from inside to outside is generated, the electric arc in the recoil pipe is quickly emptied, and the cavity effect of the outer electric arc blocks the injection of the energy of the outer electric arc. The residual electric arc enters the next recoil pipe after sequentially carrying out lightning receiving through a lightning receiving wire and conducting through the next arc striking module, and the subsequent recoil arc extinguishing process is the same as the above. Finally, the electric arc is broken at a plurality of breakpoints simultaneously, 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.

Arc electricityThe resistance will rise substantially. Because the lightning arc often serves as a constant current source in practical experience work, according to the formula W ═ I2Xrat indicates that the total energy increases and the packing temperature in the recoil tube increases, although the impact time is only a few microseconds.

The skirt 7 is arranged outside the column body, so that the arc climbing distance of the electric arc can be increased, and the electric arc is in a set path. Skirt 7 setup requirements: a skirt is required to be arranged between the upper arc nozzle 6 and the lower arc nozzle 6 in the same vertical direction, so that the electric arcs at the upper arc nozzle and the lower arc nozzle are prevented from being connected again.
Example 5:
as shown in FIG. 2, the multi-tube recoil structure can be designed into a space-like spiral structure and also can be designed into a plane zigzag arrangement. The structure is not limited to the above.

In the present application, the outer arc may be defined to have a velocity v0 at the inlet, a pressure p0, a density p0, 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.
