Description

Technical Field

[0001] The invention belongs to the field of lightning protection, and in particular relates to a counter-impact double-recoil system. Background Art

[0002] The safety of power grids is closely related to the lifeline of the national economy. Lightning damage not only causes power shortages, but also damages the national economy. In existing technologies, lightning protection mainly relies on lightning interception technology, ground grid resistance reduction technology, and lightning arrester technology, all of which have certain limitations. In the case of large arc interruption, it is difficult to control the interruption of large arcs in existing lightning protection devices. Summary of the invention

[0003] In view of the deficiencies in the prior art, the present invention discloses a counter-impact double recoil system to solve the problem of cutting off large arcs in the existing lightning protection device.

[0004] The present invention adopts the following technical solutions:

[0005] A counter-impact double recoil system comprises an upper recoil structure and a lower recoil structure, wherein the upper recoil structure and the lower recoil structure are centrally symmetrical structures that are not connected to each other, and both the upper recoil structure and the lower recoil structure are semi-enclosed cylindrical components, wherein the semi-enclosed cylindrical components comprise a lightning electrode, an arc guide ring and a recoil pipe, wherein one end of the recoil pipe is open, and the other end is fixedly provided with the lightning electrode; the arc guide ring is installed at the open end of the recoil pipe.

[0006] Furthermore: the counter-impact double recoil system also includes a partition structure; the partition structure includes a partition and an arc-guiding electrode, and the arc-guiding electrode is arranged in the middle of the partition; the partition structure is arranged vertically to divide the upper and lower recoil structures into left and right parts.

[0007] Furthermore: the counter-impact double recoil system is a semi-enclosed structure, and a nozzle is arranged at both ends of the outer wall of the counter-impact double recoil system, and the nozzle is arranged at the upper end of the arc guide ring.

[0008] Furthermore: a plurality of skirts are evenly arranged on the left and right ends of the outer wall of the counter-impact double recoil system.

[0009] Furthermore, the counter-impact recoil system can be used in a stacked manner to perform a multi-stage recoil effect on the arc.

[0010] The arc can be drawn into the recoil pipe through the arc guide ring, and the arc is recoiled by the recoil pipe, and the arc is cut off. The arc that is flushed out of the recoil pipe enters the other recoil pipe through the arc guide ring, and the above process is repeated again, and the arc is finally extinguished. Because the double recoil pipes are in an open space, air convection, radiation and heat conduction accelerate the extinction of the arc.

[0011] A partition structure is added to the double recoil system, which divides the double recoil system into two parts, the two parts realize energy exchange through the arc guide electrode in the partition. A part of the arc rushed out of the recoil tube on one side is attenuated by the convection, radiation and conduction of the air, and the other part of the residual arc passes through the arc guide electrode and enters the recoil tube on the other side to realize recoil effect again, thereby intensifying the extinction of the arc.

[0012] The counter-impact double recoil system is set as a semi-enclosed structure. As the air in the room is heated by the arc to form high pressure, the arc is forced to spray out of the closed chamber from the nozzle to achieve arc interruption. The arc ejected from the recoil tube passes through the arc guide electrode between the closed inner walls to the other side of the recoil chamber, and is pulled into the recoil pipe through the arc guide ring, and the above process is repeated again, and the arc is finally extinguished.

[0013] The advantages and beneficial effects of the present invention are:

[0014] (1) The counter-impact double recoil system can achieve effective recoil in different arc directions;

[0015] (2) Convection, radiation and heat conduction in open space structures can accelerate the recovery of dielectric strength and extinguish the arc faster;

[0016] (3) The arc-guiding electrode in the partition can effectively disperse the arc energy, making the arc easier to extinguish;

[0017] (4) The dual recoil system can be used in combination to perform multi-level recoil effects on the arc, thereby intensifying the extinguishing of the arc;

[0018] (5) This system can be applied to various lightning protection devices, including solid-phase gas arc extinguishing lightning protection devices, compressed arc extinguishing lightning protection devices, ordinary parallel gaps, lightning arresters, etc. BRIEF DESCRIPTION OF THE DRAWINGS

The arc can be drawn into the recoil pipe 3 through the arc guide ring 2, and the arc is recoiled out of the recoil pipe 3 due to the infusion recoil effect of the recoil pipe 3, so that the arc is cut off.

[0032] like Figure 4 As shown, the counter-impact double recoil system can also be used in an up-and-down manner to repeatedly fill and recoil the arc, thereby accelerating the extinction of the arc.

The recoil pipe 3 is open at one end and the lightning electrode 1 is fixedly installed at the other end; the arc guide ring 2 is installed at the open end of the recoil pipe 3. The arc can be drawn into the recoil pipe 3 through the arc guide ring 2, and the arc is recoiled out of the recoil pipe 3 due to the infusion recoil effect of the recoil pipe 3, so that the arc is cut off.

[0035] The counter-flush double recoil system also includes a baffle structure, such as Figure 3As shown, the partition structure includes a partition 4 and an arc-guiding electrode 5, and the arc-guiding electrode 5 is arranged in the middle of the partition; the partition structure is arranged vertically to divide the upper and lower recoil structures into two parts, the two parts realize energy exchange through the arc-guiding electrode 5 in the partition, and a part of the arc rushed out of the recoil pipe 3 on one side is attenuated by the convection, radiation and conduction of the air, and the other part of the residual arc passes through the arc-guiding electrode 5 and enters the recoil pipe 3 on the other side, realizing a second recoil effect, thereby intensifying the extinction of the arc.

The recoil pipe 3 is open at one end and the lightning electrode 1 is fixedly installed at the other end; the arc guide ring 2 is installed at the open end of the recoil pipe 3; a nozzle is arranged at both ends of the outer wall of the semi-enclosed counter-type double recoil system, and the nozzle is arranged at the upper end of the arc guide ring 2.

[0039] The counter-impact double recoil system is set as a semi-enclosed structure. As the air in the room is heated by the arc to form a high pressure, the arc is forced to be ejected from the nozzle to the closed room, thus achieving arc interruption. The arc ejected from the recoil pipe 3 passes through the arc guide electrode 5 between the closed inner walls to the other side of the recoil chamber, and is drawn into the recoil pipe 3 through the arc guide ring 2, and the above process is repeated again, and the arc is finally extinguished.

The upper and lower counter-impact double recoil systems are electrically connected by connecting the lightning electrode 1 to ensure that the arc can smoothly enter the semi-enclosed counter-impact double recoil system below.

As the air in the room is heated by the arc to form a high pressure, the arc is forced to spray out of the closed chamber from the nozzle, thus achieving arc interruption. The arc ejected from the recoil pipe 3 passes through the arc guide electrode 4 between the closed inner walls to the other side of the recoil chamber, and is drawn into the recoil pipe 3 through the arc guide ring 2, and the above process is repeated again, finally extinguishing the arc.

[0044] like Figure 8 As shown, a plurality of skirts 6 are evenly arranged at the left and right ends of the outer wall of the counter-impact double recoil system, which can increase the creepage distance and avoid arc discharge along the surface.
