When a transmission line is struck by lightning, the line insulator flashes over, and the subsequent power frequency follow current damages the insulator string and fittings, resulting in the burning of the insulator string and the breaking of the conductor.

[0003] The existing lightning protection devices for transmission lines mainly use lightning protection gap devices for transmission lines. However, the key to lightning protection of the existing lightning protection gap devices is to use a gas generator for arc extinguishing treatment. However, the arc extinguishing effect of the existing gas generating device is not good, the direction of the gas ejected by the gas generating device is uncontrollable, the pressure of the ejected gas is not high enough, the ejection time is short, and the gas generating material cannot be completely burned, resulting in the inability to completely blow out the arc.

Therefore, a gas pressurizing device is proposed. Summary of the Invention

[0011] Further, a base support member is arranged between the upper end of the air pill base and the limiting frame, and the base support member is composed of more than one hoop.

[0012] Further, the air pill includes a material confinement layer, gunpowder, and solid oxygen or liquid oxygen. The gunpowder and solid oxygen or liquid oxygen are mixed and sealed in the material confinement layer, and the rupture pressure value of the material confinement layer is less than the pressure increment value inside the sleeve and the limiting frame.

[0013] Further, the trigger signal input terminal is in contact with the gunpowder inside the air pill by arranging a plurality of heating resistance wires. The plurality of heating resistance wires are arranged in parallel and are connected to the trigger signal input terminal.

[0014] Further, the limiting frame, the sleeve, and the material confinement layer are made of the same type of metal material, and the thickness of the limiting frame and the sleeve is proportional to the amount of gunpowder.

[0015] Further, the size of the air injection hole is 5-8 mm, the gas generated by the air pill is ejected from the air injection hole, the limiting frame includes a top plate, a bottom plate, and two side plates, and the two ends of the two side plates are respectively connected to one side of the top plate and the bottom plate.

[0029] To make the objectives, technical solutions and advantages of the present invention more clearly understood, the following provides preferred embodiments with reference to the accompanying drawings to further elaborate on the present invention. However, it should be noted that many details listed in the specification are only for enabling the reader to have a thorough understanding of one or more aspects of the present invention, and these aspects of the present invention can be implemented even without these specific details.

[0030] The following is an explanation of some technical principles used in the present invention:

[0031] Bending moment is a type of internal moment on a stressed member. Popularly speaking: bending moment is a kind of moment. Its standard definition is: the resultant couple moment of the distributed internal force system perpendicular to the cross-section; calculation formula: M = θ·EI / L, where θ is the torque, EI is the rotational stiffness, and L is the effective calculated length of the member.

[0032] According to the characteristics of the bending moment, since the strength at the air outlet is much smaller than that of the wrapping layer, a large bending moment will be generated, making the jet airflow concentrated and intense, and greatly improving the arc extinguishing effect; moreover, the pressure increment can be controlled by controlling the area of the uncovered air outlet. The pressure inside the sleeve and the limit frame increases, the bending moment at the air injection hole increases, and high-pressure airflow is ejected.

[0033] The relationship between the burning rate and the pressure satisfies the following formula: u n = a + bP v ; The influence of pressure on the burning rate is the greatest. Within a certain range, the greater the pressure, the greater the burning rate, and high pressure may turn into detonation. Mechanism of the transition from explosive combustion to detonation: The sealing strength is improved, and the combustion products have no time to diffuse, causing the pressure in the reaction zone to continuously increase, resulting in an increase in the burning rate. When the burning rate reaches the critical value, the combustion is destroyed and turns into detonation.

[0034] The process of explosive combustion propagates in the form of a combustion reaction wave. The energy in the reaction zone during the propagation of the combustion wave is transmitted outward through heat conduction, radiation, and the diffusion of combustion gas products. Therefore, the combustion propagation speed is related to factors such as explosive properties, pressure, charge diameter, and the presence or absence of a casing.

[0035] Reasons for the increase in the explosive burning rate with increasing pressure: 1. At high pressure, the collision chance of gas-phase activated molecules is large, and the gas-phase reaction speed is high; 2. At high pressure, the penetration of gas-phase high-temperature products into the condensed-phase explosive increases. Therefore, in the solid-phase arc extinguishing and lightning protection device, the burning rate of the gas pill can be controlled by controlling the pressure in the space where the gas pill is located.

[0036] Based on the above principle explanation and referring to Figures 1 - 8 The following further elaborates on the embodiments of the present invention:

[0037] Embodiment 1:

[0038] An integrated gas supercharging device, such asFigures 1 - 4 As shown in the figure, it includes a trigger signal input terminal 1, a limit frame 2, a sleeve 3, a gas pill base 4, a gas pill 5, and an air jet hole 6. The trigger signal input terminal 1 is arranged on the gas pill base 4. The gas pill base 4 is connected to the gas pill 5. The sleeve 3 is sleeved outside the gas pill 5. The limit frame 2 is sleeved outside the sleeve 3 and the gas pill base 4. The limit frame 2 is provided with the air jet hole 6. When the pressure inside the sleeve and the limit frame increases, the bending moment at the air jet hole increases, and high-pressure air flow is ejected. Both the limit frame 2 and the sleeve 3 are set as rigid structures. Among them, the width of the gas pill base 4 is generally wider than that of the gas pill 5. The gas pill 5 is set as a cylindrical structure or a square structure, etc. Other structures not mentioned are within the protection scope of this application. Among them, the structure of the sleeve 3 is the same as the structural shape of the gas pill 5 and is closely attached to the outside of the gas pill 5.

[0039] The sum of the base pressure of the gas pill 5 and the incremental pressure of the limit frame 2 or the sum of the incremental pressure of the sleeve 3 is greater than the critical pressure for the gas-producing material inside the gas pill 5 to rupture. The base pressure of the gas pill 5 is the reaction force of the extrusion force when the gunpowder wrapped inside the gas pill 5 is not burning. That is, when the sleeve 3 is tightly wrapped with the gas pill 5, the gas pill 5 will generate an outward tension on the sleeve 3, which is the base pressure of the gas pill 5. The incremental pressure of the sleeve 3 is the pressure applied outward to the sleeve 3, and the limit pressure at which the sleeve 3 just ruptures is the incremental pressure of the sleeve 3. The incremental pressure of the limit frame 2 is the outward pressure above and below the limit frame 2, and the limit pressure at which the limit frame 2 just ruptures is the incremental pressure of the limit frame 2. The critical pressure for the gas pill 5 to rupture is the pressure when the internal fuel inside the gas pill 5 is completely burned and the maximum pressure of the generated gas is reached. That is, the high-strength limit frame 2 and the sleeve 3 wrapping the gas pill 5 will not cause detonation, but after complete combustion, the high-pressure gas is ejected from the air jet hole 6.

[0040] The gas pill 5 is nested inside the sleeve 3, and the sleeve 3 wraps around the side of the gas pill 5. The top of the limit frame 2 is in close contact with the bottom of the gas pill base 4, and the bottom is in close contact with the bottom of the gas pill 5 or the bottom of the sleeve 3. The sleeve 3 tightly nests and wraps the gas pill 5 radially, and the thickness of the inner wall of the sleeve 3 is processed so that it will not shift or expand, etc. The huge air pressure of the gas pill 5 is constrained by the sleeve 3, and all the gases generated after the combustion of the gas-producing materials in the gas pill 5 are under all the pressures borne by the sleeve 3. In the vertical direction, the limit frame 2 limits the high-pressure gas generated in the gas pill 5 at the upper and lower ends, so that the upper and lower ends do not expand or burst, etc. The top of the limit frame 2 is designed with a trigger signal input port, and a trigger signal input terminal 1 is arranged on the trigger signal input port for the gas pill 5 to receive the lightning trigger signal. The limit frame 2 is provided with an air jet hole 6, and the gas jets out from this uncovered air jet hole 6 and the jet direction is controllable. By making the aperture of the provided air jet hole 6 smaller and setting the position according to needs, the situation of controllable direction is realized in comparison with the original detonation method. The limit frame 2 and the sleeve 3 are made of high-strength materials, such as aluminum steel, etc.

[0041] After the gas pill 5 receives the trigger signal input by the trigger signal input terminal 1, gas is quickly generated inside the gas pill 5. Since the strength of the sleeve 3 and the limit frame 2 is very good, far greater than the pressure of the gas generated by the gas pill 5, the sleeve 3 and the limit frame 2 will not rupture and cause a detonation situation. After the gas pressure generated inside the gas pill 5 is greater than the maximum bearing pressure on the surface layer of the gas pill 5, all the gas generated by the gas pill 5 can only jet out from the air jet hole 6, so that the pressure of the jetted gas increases, and at the same time, the jet direction control operation is realized according to the set size and position of the air jet hole 6. And during the combustion process of the gas pill 5, the internal gas pressure increases, making the combustion speed faster and the arc extinguishing reaction time shorter.

[0042] Such as Figure 7As shown, curve S1 is a graph showing the relationship between time and gas pressure for the arc extinguishing effect of a conventional gas generator, and curve S2 represents the graph showing the relationship between time and gas pressure for the arc extinguishing effect of the device of the present invention. By comparison, it can be known that the reaction time required for the conventional gas generator to start arc extinguishing is t2, while the reaction time required for using the device of the present application is t1, and t2 is greater than t1. The comparison for this time difference is that the sleeve 3 and the limit frame 2 provided in the device of the present application radially constrain the air flow, and the limit frame axially constrains the air flow. The pressure inside the sleeve and the limit frame increases, the bending moment at the air injection hole increases, and high-pressure air flow is ejected. The sum of the base pressure of the gas pellet 5 and the incremental pressure of the sleeve 3 is greater than the critical pressure for the rupture of the gas pellet 4, and at the same time, the sum of the base pressure of the gas pellet 5 and the incremental pressure of the limit frame 2 is greater than the critical pressure for the rupture of the gas pellet 4, so that the gas pellet 4 generates gas at the moment of being ignited and the wrapping layer 2 does not deform, and the gas pressure rises rapidly. While the conventional gas generator will undergo a certain deformation and increase in volume when generating gas, resulting in a lower gas pressure rise than that of the gas in the present application. According to the relationship between the burning rate and the pressure: the greater the pressure, the greater the burning rate, so that the burning speed inside the gas pellet 4 of this device will be faster than the burning speed of the fuel inside the conventional gas generator, thus the jetting time of this device will be faster than the jetting time of the conventional gas generator, that is, the arc extinguishing reaction time is faster.

[0043] At the same time, comparing the arc extinguishing pressure and the arc extinguishing time, the maximum pressure at the detonation moment of the conventional gas generator in curve S1 is P1, and the time period to reach this pressure is very short, only at the moment of detonation, resulting in a poor arc extinguishing effect. In the device of the present application, the time to reach the pressure P1 during arc extinguishing is the time period from t1 - t3, which is also called the high-pressure arc extinguishing time. The time t1 - t3 is longer than the entire arc extinguishing time of the conventional gas generator. Therefore, the arc extinguishing effect is very good, and arcs generated by larger voltage transmission lines can all be extinguished. The reason for the above is that the gas of this device can only be ejected from the air injection hole 6, while the conventional gas generator directly detonates and sprays in multiple directions, resulting in a very short high-pressure arc extinguishing time. And the high-pressure gas of this device needs a time process of t1 - t3 to be ejected from the air injection hole 5. Therefore, the arc extinguishing gas pressure is high and the gas ejection time is long, making the arc extinguishing effect better, and it can spray and extinguish arcs in special occasions and at higher voltage levels. Among them, the value of P2 is about ten times that of P1, with a stronger arc extinguishing jet pressure.

[0044] Example 2:

[0045] The air vent 6 is arranged at the opposite end of the trigger signal input terminal 1, and the trigger signal input terminal 1 is in contact with the gas pellet 5. By arranging the air vent 6 and the trigger signal input terminal 1 at the opposite ends, the air pressure can be instantaneously pressed against the material binding layer of the air vent 6 only after the gunpowder in the gas pellet 5 structure burns completely, enabling the gas-producing material in the gas pellet 5 to burn more completely, with a greater gas pressure, which can extinguish the arc generated by higher-voltage power transmission, resulting in a better arc extinguishing effect.

[0046] Embodiment 3:

[0047] The sleeve 3 is arranged in a cylindrical structure, and the cylindrical structure is composed of a plurality of detachable circular hoops 10, and the circular hoops 10 are detachably connected to each other. The circular hoops 10 are connected by threads or buckles, so that the gas pellets 5 of corresponding lengths can be set according to the voltage of the transmission line where arc extinguishing is required. When the width or diameter of the gas pellet 5 is certain, the higher the voltage of the transmission line where arc extinguishing is required, the longer the length of the gas pellet 5, so that the pressure of the arc extinguishing gas is higher, the arc extinguishing time is longer, and the arc extinguishing effect is better, and the arc generated by a higher-voltage transmission line can be extinguished. At the same time, it is also convenient for the installation of the sleeve 3. According to the length of the gas pellet 5, the number of connected circular hoops 10 can be determined. Generally, the length of the gas pellet 5 is an integer multiple of the length of the circular hoop 10.

[0048] Embodiment 4:

[0049] The present invention further includes a sealing ring gasket 7, which is arranged at the edge of the air vent 6, and the sealing ring gasket 7 is arranged between the limit frame 2 and the gas pellet 5 and is in close contact. In order to increase the tightness between the limit frame 2 and the gas pellet 5, a sealing gasket is added at the air outlet gap of the limit frame 2. The sealing ring gasket 7 is mainly used in cooperation with the sleeve 3 with a bottom opening. The sealing ring gasket 7 can effectively control the size of the gas ejection port to be the same as that of the air vent 6, making the bending moment of the outer layer of the gas pellet 5 larger, so that the internal air pressure increases as the bending moment increases, and the ejected air pressure is higher.

[0050] Embodiment 5:

[0051] The sleeve 3 is arranged in a cylindrical structure, and a cylindrical air jet port is arranged at the bottom of the cylindrical structure. The center of the cylindrical air jet port and the center of the air vent 6 are arranged on the same straight line. The bottom of the cylindrical structure is arranged as a bottom structure, and then a cylindrical air jet port is opened in the bottom structure, and the cylindrical air jet port coincides with the air vent 6.

[0052] Embodiment 6:

[0053] There is a base support member 8 disposed between the upper end of the air pellet base 4 and the limit frame 2. The base support member 8 is composed of more than one circular hoop 10. The setting of the base support member 8 is for better installation. When fixing the limit frame 2, air pellets 5 of different lengths can be installed without having to mold different limit frames 2 for air pellets 5 of different lengths, which is more convenient for manufacturing and installation. Therefore, regardless of the length of the air pellet 5, the same length of limit frame 2 and sleeve 3 can be used. This greatly reduces the manufacturing cost and installation cost, and has good economic benefits.

[0054] Embodiment 7:

[0055] The air pellet 5 includes a material confinement layer, gunpowder, and solid oxygen or liquid oxygen. The gunpowder and solid oxygen or liquid oxygen are mixed and sealed inside the material confinement layer. The rupture pressure value of the material confinement layer is much smaller than the pressure increment value inside the sleeve and the limit frame, and the incremental pressure of the material confinement layer is less than the critical pressure for the rupture of the gunpowder. After the gunpowder is ignited, the solid oxygen or liquid oxygen provides the oxygen for combustion, and as the temperature rises, both the solid oxygen or liquid oxygen will vaporize, providing an additional gas pressure, forming the effect of secondary pressurization, so that the gas pressure increases faster. When the gas pressure generated when the gunpowder is basically completely burned is greater than the critical pressure for the rupture of the material confinement layer, the material confinement layer at the air ejection hole 6 ruptures, and the gas ejects from the air ejection hole 6 to extinguish the arc.

[0056] Embodiment 8:

[0057] The trigger signal input terminal 1 is arranged in contact with the gunpowder inside the air pellet 5 by setting a plurality of heating resistance wires. The plurality of heating resistance wires are arranged in parallel and are connected to the trigger signal input terminal. By arranging the heating resistance wires in parallel, the effect of multi-point ignition is achieved, which can shorten the reaction time, that is, shorten the reaction time for arc extinguishing, and the arc extinguishing is faster.

[0058] The trigger signal input terminal 1 inputs a current signal, the resistance wires heat up, the gunpowder inside the air pellet burns to generate high-pressure gas, the limit frame 2 axially restricts the high-pressure gas, the sleeve 3 radially restricts the high-pressure gas, the pressure of the high-pressure gas is greater than the bending moment of the material confinement layer at the air ejection hole, the pressure inside the sleeve and the limit frame increases, the bending moment at the air ejection hole increases, and the high-pressure gas ejects from the air ejection hole. The position of the air ejection hole 6 is set to control the jet direction. When the air pellet 5 receives the electrical signal from the trigger signal input terminal 1, a large amount of arc extinguishing gas will be triggered.

[0059] The high-strength limiting frame 2 and the sleeve 3 radially and axially constrain the airflow, and the incremental pressure of the gas pellets 5 in the sleeve 3 increases rapidly. Since the strength at the air outlet is much smaller than that of the sleeve 3 and the aperture of the air jet hole 6 becomes smaller, a large bending moment will be generated. When the sum of the base pressure of the gas pellet 5 and the incremental pressure of the wrapping layer is greater than the critical pressure for the rupture of the gas-generating material, due to the high-strength wrapping, the burning rate of the gas-generating material increases, the combustion integrity improves, and the combustion is more complete. The pressure in the sleeve and the limiting frame increases, the bending moment at the air jet hole increases, and high-pressure airflow is ejected. The airflow is ejected from the unwrapped air outlet, and the ejection direction of the air outlet is controllable. The ejected airflow is concentrated and strong, and the arc extinguishing effect is greatly improved. By increasing the sealing strength, the materials in the gas pellet 4 burn sufficiently to generate a greater critical release air pressure, generating a high-speed arc extinguishing airflow while arcing, acting on the arc channel, blocking the subsequent power frequency arc building process, and being able to extinguish the power frequency arc in a very short time. Its arc extinguishing time is much shorter than the operating time of the circuit breaker. Among them, the gas generation of the arc extinguishing unit directly affects the arc extinguishing effect.

[0060] Example 9:

[0061] The limiting frame 2, the sleeve 3 and the material binding layer are made of the same type of metal material, and the thicknesses of the limiting frame 2 and the sleeve 3 are proportional to the amount of gunpowder. Since the lightning protection device is installed on the transmission line for a long time, it will be exposed to sunlight and rain. If different metals are used, a potential difference will be formed between the material binding layer and the radial kit or the wrapping layer. After the potential difference is formed, corrosion is likely to occur, thus greatly shortening the service life of the lightning protection device. Using the same type of metal material can effectively prevent the occurrence of the above situation.

[0062] Example 10:

[0063] The size of the air jet hole 6 is 5 - 8 mm. The gas generated by the gas pellet 5 is ejected from the air jet hole. The limiting frame 2 includes a top plate, a bottom plate and two side plates. The two ends of the two side plates are respectively connected to one side of the top plate and the bottom plate. The limiting frame 2 is set as an integrally formed structure.

[0064] The airflow is ejected from the unwrapped air jet hole 6. The ejection direction of the air jet hole 6 is controllable. The ejected airflow is concentrated and strong, and the arc extinguishing effect is greatly improved. The general original ejection holes are generally more than a dozen millimeters, resulting in too large an ejection range, too short an ejection time, and poor arc extinguishing effect. According to the bending moment calculation formula: M = θ·EI / L, where θ is the torque, EI is the rotational stiffness, and L is the effective calculated length of the rod. When θ is the torque and EI is the rotational stiffness are the same, after L becomes shorter, the bending moment becomes larger, that is, the pressure of the ejected gas becomes larger. And since the air jet hole 6 is smaller, the same gas takes a longer time to be ejected, that is, the arc extinguishing time is longer, achieving an increase in the arc extinguishing gas pressure and an increase in the arc extinguishing time, resulting in a better arc extinguishing effect.
