Embodiment 1

[0036] A simple all-in-one gas booster device such as Figure 1-Figure 3 As shown, it includes a trigger signal input terminal 1, a wrapping layer 2, an air pill base 3, an air pill 4 and an air injection hole 5, the trigger signal input terminal 1 is arranged on the air pill base 3, and the air pill 4 is arranged on the air pill One side of the ball base 3, the wrapping layer 2 is wrapped on the outside of the air pill base 3 and the air pill 4, and is arranged in a fit manner, and the joint of the wrapping layer 2 and the air pill 4 is provided with an air injection hole 5, and the The wrapping layer 2 is set as a hard layer, and the sum of the base pressure of the air pill 4 and the incremental pressure of the wrapping layer 2 is greater than the critical pressure for the bursting of the air pill 4 . The base pressure of the air pill 4 is when the air pill 4 does not burn, the reaction force of the extruding force of the wrapped gunpowder, that is, when the wrapping layer 2...

Embodiment 2

[0043] The gas injection hole 5 is arranged at the opposite end of the trigger signal input terminal 1 , and the trigger signal input terminal 1 is arranged in contact with the gas pill 4 . By setting the gas injection hole 5 and the trigger signal input terminal 1 at the opposite end, the air pressure will be instantly pressed to the material binding layer of the gas injection hole 5 after the gunpowder in the structure of the gas pill 4 is completely burned, so that the gas producing material in the gas pill 4 The combustion is more complete and the gas pressure is higher, which can extinguish the arc generated by higher voltage power transmission, making the effect of arc extinguishing better.

Embodiment 3

[0045] The gas pill 4 includes a material-constrained layer, gunpowder and solid oxygen or liquid oxygen, and the propellant and solid oxygen or liquid oxygen are mixed and sealed in the material-constrained layer, and the incremental pressure of the material-constrained layer is less than the critical pressure for the rupture of the gunpowder. The rupture pressure value of the material-bound layer is much smaller than the pressure increment value in the cladding layer.

[0046] After the gunpowder is ignited, the solid oxygen or liquid oxygen provides the oxygen for combustion, and the temperature rises, the solid oxygen or liquid oxygen will be vaporized, providing an additional gas pressure, forming the effect of secondary pressurization, and increasing the gas pressure faster. The gas pressure generated when the gunpowder is almost completely burned will be greater than the critical pressure for the rupture of the material-constrained layer, so that the material-constraine...

Abstract

The invention discloses a simple integrated gas pressurization device, and belongs to the field of power transmission line lightning protection devices. The simple integrated gas pressurization devicecomprises trigger signal input terminals, a wrapping layer, a gas pill base, a gas pill and a gas spraying hole, wherein the trigger signal input terminals are arranged on the gas pill base, the gaspill is arranged on one side of the gas pill base, the wrapping layer wraps the outer side of the gas pill base and the outer side of the gas pill and is attached to the gas pill base and the gas pill, the gas spraying hole is formed in the attaching position of the wrapping layer and the gas pill, the pressure in the wrapping layer is increased, the bending moment at the gas spraying hole is increased, and high-pressure airflow is sprayed. According to the device, the safety capability of the solid-phase arc extinguishing lightning protection device can be improved, and the external structurecannot be damaged under the condition that the external structure is not reinforced; and the gas pressure intensity is enhanced by improving the sealing strength of the gas production unit, so that the gas production material fuel is combusted more fully, the gas production is more centralized and the direction is controllable, and the arc extinguishing effect is further improved.

Description

technical field [0001] The invention relates to the field of lightning protection devices for transmission lines, in particular to a simple integrated gas booster device. Background technique [0002] Lightning protection of transmission lines has always been an important part of the lightning protection work of the power sector, and lightning faults are still one of the important factors affecting the safety of the power grid. Lightning strikes on transmission lines cause flashover of line insulators, and the resulting power frequency freewheeling damages insulator strings and fittings, resulting in burnt insulator strings and wire burnout accidents. [0003] Existing lightning protection devices for transmission lines mainly use transmission line lightning protection gap devices, but the key to lightning protection used in existing lightning protection gap devices is to use gas generators for arc extinguishing treatment. However, the arc extinguishing effect of the existi...
