Lightning faults are still one of the important factors affecting the safety of the power grid. For a long time, lightning factors have been the main cause of transmission line faults and tripping. When lightning strikes a transmission line, it causes the insulators on the transmission line to flash over. The resulting power frequency continuous current damages the insulator string and hardware, causing the insulator string to burn and the conductor to burn out. For this reason, the power sector generally installs line lightning arresters on the transmission line to achieve protection. The application number of a Chinese patent is: 201610747255.3, and the patent name is: Lightning induced solid phase arc extinguishing lightning arrester.

[0045] Embodiment 10:

[0046] like Figure 4-5The gas boosting component 9 is arranged in the gas boosting component groove 5, and the gas boosting component 9 includes a trigger signal input terminal, a limit barrel, a sleeve, a gas pill base, a gas pill and an air jet hole. The trigger signal input terminal is arranged on the gas pill base, and the gas pill base is connected to the gas pill. The sleeve is sleeved on the outside of the gas pill, and the limit barrel is clamped on the outside of the sleeve and the gas pill base. The limit barrel is provided with an air jet hole. The pressure in the gas boosting component increases, the bending moment at the air jet hole increases, and a high-pressure airflow is ejected. The sum of the basic pressure of the gas pill and the incremental pressure of the limit barrel and / or the incremental pressure of the sleeve is greater than the critical pressure of the rupture of the gas-producing material in the gas pill, and the limit barrel and the sleeve are both configured as hard structures.

[0047] The jet hole is arranged at the opposite end of the trigger signal input terminal, and the trigger signal input terminal is arranged in contact with the gas pellet. The sleeve is arranged as a cylindrical structure, and the cylindrical structure is composed of a plurality of detachable hoops, and the hoops are detachably connected. The above scheme also includes a sealing ring gasket, which is arranged at the edge of the jet hole, and the sealing ring gasket is arranged between the limit frame and the gas pellet, and is arranged in close contact. The sleeve is arranged as a barrel structure, and a barrel jet port is arranged at the bottom of the barrel structure, and the center of the barrel jet port and the center of the jet hole are arranged on the same straight line. The gas pellet includes a material binding layer, gunpowder and solid oxygen or liquid oxygen, and the gunpowder and solid oxygen or liquid oxygen are mixed and sealed and placed in the material binding layer. The rupture pressure value of the material binding layer is much smaller than the pressure increment value in the sleeve and the limit frame, and the incremental pressure of the material binding layer is smaller than the critical pressure of the gunpowder rupture. The trigger signal input terminal is arranged in contact with the gunpowder inside the gas pellet by arranging a plurality of heating resistance wires, and the plurality of heating resistance wires are arranged in parallel and connected to the trigger signal input terminal. The bottom of the limiting barrel is set as an open structure, and a bottom wall is set on the side of the bottom of the limiting barrel. After the gas ball base and the gas ball are inserted into the limiting barrel, the bottom wall is folded inward by mechanical extrusion, and forms an angle of 85°-95° ​​with the side wall of the limiting barrel. The air jet hole is set on one side of the top of the limiting barrel. The limiting barrel is set as a built-in hollow cylindrical structure, including a sleeve bottom plate, a side wall and a top cover. The sleeve bottom plate and the top cover are respectively set at both ends of the side wall. The top cover or the sleeve bottom plate is movably connected or detachably connected to the side wall. The top cover is provided with a top cover air jet hole, and the top cover air jet hole and the air jet hole are set on the same straight line. The top cover or the sleeve bottom plate is clamped with the side wall by setting a buckle.

[0048] The gas pellet is nested in the sleeve, and the sleeve wraps the side of the gas pellet. The top of the limit barrel is set in close contact with the base of the gas pellet, and the bottom is set in close contact with the bottom of the gas pellet or in close contact with the bottom of the sleeve. The sleeve tightly nests and wraps the gas pellet radially, and processes the thickness of the inner wall of the sleeve so that it will not deviate or expand. The huge air pressure of the gas pellet is restrained by the sleeve, and the gas generated by the combustion of all gas-producing materials in the gas pellet bears all the pressure in the sleeve. In the vertical direction, the limit barrel limits the upper and lower ends of the high-pressure gas generated in the gas pellet so that the upper and lower ends do not expand or burst. The top of the limit barrel is designed with a trigger signal input port, and a trigger signal input terminal is set on the trigger signal input port for the gas pellet to receive a lightning trigger signal. The limit barrel is provided with a jet hole, and the gas is ejected from this unwrapped jet hole and the ejection direction is controllable. The aperture of the jet hole is reduced, and at the same time, according to the position set as needed, the direction is controllable compared with the original detonation method. The limit barrel and sleeve are made of high-strength materials such as aluminum steel.

[0049] After the gas pellet receives the trigger signal input from the trigger signal input terminal, gas is rapidly generated inside the gas pellet. Since the strength of the sleeve and the limit barrel is very good, the pressure is much greater than the pressure of the gas generated by the gas pellet, so the sleeve and the limit barrel will not break and cause explosion. After the gas pressure generated inside the gas pellet 5 is greater than the maximum bearing pressure of the surface of the gas pellet, the gas generated by the gas pellet can only be ejected from the jet hole, thereby increasing the pressure of the ejected gas, and at the same time, the jet direction can be controlled according to the size and position of the jet hole. In addition, during the combustion process of the gas pellet, the internal gas pressure increases, which makes the combustion speed faster and the arc extinguishing reaction time shorter.

[0050] like Figure 4As shown, curve S1 is a time and gas pressure relationship diagram of the arc extinguishing effect of an ordinary gas generator, and curve S2 is a time and gas pressure relationship diagram of the arc extinguishing effect of the device of the present invention. By comparison, it can be known that the reaction time required for the ordinary gas generator to start arc extinguishing is t2, while the reaction time required for the device of the present application is t1, and t2 is greater than t1. The comparison that causes this time difference is that the sleeve and the limit barrel set in the device of the present application produce radial constraints on the airflow, and the limit barrel produces axial constraints on the airflow. The pressure in the sleeve and the limit barrel increases, the bending moment at the jet hole increases, and the high-pressure airflow is ejected. The sum of the basic pressure of the gas ball and the incremental pressure of the sleeve is greater than the critical pressure of the gas ball rupture. At the same time, the sum of the basic pressure of the gas ball and the incremental pressure of the limit barrel is greater than the critical pressure of the gas ball rupture, so that the gas ball generates gas at the moment of being ignited, and the limit barrel will not deform, and the gas pressure rises rapidly. The ordinary gas generator will undergo a certain deformation when generating gas, and the volume increases, so that the gas pressure increase is not as high as the gas pressure of the present application. According to the relationship between burning rate and pressure: the greater the pressure, the greater the burning rate, so that the burning speed in the gas pellet of this device will be faster than the burning speed of the fuel in the ordinary gas generator, so that the injection time of this device will be faster than the injection time of the ordinary gas generator, and the arc extinguishing reaction time will be faster.

[0051] At the same time, the pressure and time of arc extinguishing are compared. In the curve S1, the maximum pressure of the ordinary gas generator at the moment of detonation is P1, and the time period to reach this pressure is very short, only at the moment of detonation, which makes the arc extinguishing effect poor. In the device of the present application, the time to reach the pressure of P1 during arc extinguishing is t1-t3, which is also called the high-voltage arc extinguishing time. The time t1-t3 is greater than the entire arc extinguishing time of the ordinary gas generator, so the arc extinguishing effect is very good, and the arcs generated by the larger voltage transmission line can be extinguished. The reason for the above is that the gas of the present device can only be ejected from the jet hole, while the ordinary gas generator is directly detonated and ejected in multiple directions, making the time of high-voltage arc extinguishing very short. The high-pressure gas of the present device needs a time process of t1-t3 to be ejected from the jet hole, so the arc extinguishing gas pressure is high and the time of ejecting gas is long, so the arc extinguishing effect is better, and arcs of special occasions and higher voltage levels can be ejected. Among them, the value of P2 is about ten times that of P1, with a stronger arc extinguishing jet pressure.

[0052] The top cover and side wall of the limit barrel are set as an integrally formed structure, and the sleeve bottom plate and the side wall are set as a movable connection or a detachable connection structure, so as to better reduce the leakage during the jetting. The case of opening the cover at one end or both ends can well realize the mechanized assembly, greatly improve the speed and rate of installation, reduce the production cost and processing cost, and improve the economic benefit.

[0053] After the gunpowder is ignited, solid oxygen or liquid oxygen provides oxygen for combustion, and as the temperature rises, the solid oxygen or liquid oxygen will vaporize, providing an additional gas pressure, forming a secondary pressurization effect, which increases the gas pressure faster. When the gunpowder is basically completely burned, the gas pressure generated will be greater than the critical pressure of the material binding layer rupture, causing the material binding layer at the jet hole to rupture, and gas will be ejected from the jet hole to extinguish the arc.

[0054] In order to increase the airtightness between the limit barrel and the gas pellet, a closed gasket is added to the gap of the limit barrel outlet. The sealing ring gasket is mainly used with the sleeve with an empty bottom. The sealing ring gasket can control the size of the gas outlet to be the same as the size of the jet hole. The pressure in the sleeve and the limit barrel increases, the bending moment at the jet hole increases, and high-pressure airflow is ejected. The bending moment of the outer layer of the gas pellet increases, and the internal air pressure increases with the increase in the bending moment, and the ejected air pressure is higher. The sealing ring gasket is made of elastic material.

[0055] By setting the jet hole and the trigger signal input terminal at opposite ends, the gas pressure will instantly press the material binding layer of the jet hole only after the gunpowder in the gas ball structure is completely burned, so that the gas-producing material in the gas ball can burn more completely and the gas pressure is greater, which can extinguish the arc generated by higher voltage power transmission, making the arc extinguishing effect better.

[0056] The trigger signal input terminal inputs a current signal, the resistance wire heats up, the gunpowder in the gas pill burns to produce high-pressure gas, the limit frame constrains the high-pressure gas axially, the sleeve constrains the high-pressure gas radially, the pressure in the sleeve and the limit barrel increases, the bending moment at the jet hole increases, the pressure of the high-pressure gas is greater than the bending moment of the material binding layer at the jet hole, and the high-pressure gas is ejected from the jet hole. The position of the jet hole is set to control the jet direction. When the gas pill receives the electrical signal from the trigger signal input terminal, it will trigger the generation of a large amount of arc-extinguishing gas.

[0057] The high-strength limit frame and sleeve constrain the airflow radially and axially, and the incremental pressure of the gas ball in the sleeve increases rapidly. As the pressure in the sleeve and the limit barrel increases, the bending moment at the jet hole increases, and high-pressure airflow is ejected. Since the strength at the outlet is much smaller than that of the sleeve, and the aperture of the jet hole becomes smaller, a large bending moment will be generated. When the sum of the basic pressure of the gas ball and the incremental pressure of the wrapping layer is greater than the critical pressure of the gas-producing material rupture, the airflow is ejected from the unwrapped outlet, and the outlet ejection direction is controllable. The ejection airflow is concentrated and strong, and the arc extinguishing effect is greatly improved. By improving the sealing strength, the material in the gas ball is fully burned to produce a greater critical release pressure, and a high-speed arc extinguishing airflow is generated while the arc is being built, which acts on the arc channel, blocks the subsequent power frequency arc building process, and can extinguish the power frequency arc in a very short time. The arc extinguishing time is much shorter than the circuit breaker action time. Among them, the gas production of the arc extinguishing unit directly affects the arc extinguishing effect.

[0058] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
