Abstract
Description
Technical Field
[0001] This invention relates to a reactor protection device. Background Technology
[0002] A reactor is an inductive high-voltage electrical appliance used in a power system to limit short-circuit current, compensate reactive power, and perform phase shifting, while a dry-type air-core reactor is a reactor whose windings are not immersed in insulating liquid.
[0003] A search revealed that Chinese patent CN222762769U discloses "a lightweight dry-type air-core reactor, comprising an upper star frame, a reactor coil, a lower star frame, an equalizing ring, and a post insulator; the upper star frame is provided at the upper end of the reactor coil, and the lower star frame is provided at the lower end; an equalizing ring is provided on both the upper and lower star frames; the bottom of the lower star frame is a flange; and a post insulator is provided at the bottom of the reactor coil. This invention uses a novel insulating composite film to wrap rectangular transposed aluminum stranded wire to encapsulate the reactor, eliminating the traditional method of using epoxy resin impregnated alkali-free glass fiber to wrap the protective insulation layer. The lightweight reactor has the characteristics of small size, light weight, and good heat dissipation performance." However, it still has the following drawbacks:
[0004] The insulation system of this reactor mainly relies on multiple layers of insulation film. Under long-term operation, moisture, salt spray and various chemical pollutants in the air can easily penetrate and erode the insulation film layer, greatly increasing the risk of surface flashover (pollution flashover) caused by surface contamination and moisture, which seriously threatens the reliability and safety of power grid operation. Summary of the Invention
[0005] The purpose of this invention is to solve the problem that the multilayer insulation film of existing reactors is easily penetrated and eroded, resulting in poor reliability and safety of power grid operation. This invention proposes a pollution-resistant flashover dry-type air-core reactor based on a nano-coating.
[0006] The present invention discloses a pollution flashover-resistant hollow reactor based on a nano-coating, comprising a reactor body; and further comprising protective components and auxiliary components;
[0007] The protective assembly is fixed to the top of the reactor body via an auxiliary assembly;
[0008] The protective assembly includes an upper star-shaped frame, a support block, a support plate, and a protective top; wherein, the upper star-shaped frame is fixedly installed on the top of the reactor body; the support block is bolted to the upper star-shaped frame, the support plate is bolted to the support block, and the other end of the support plate is fixedly connected to the protective top, which has a conical structure.
[0009] Furthermore, the auxiliary component includes a retaining ring and a reinforcing post;
[0010] The fixing ring is fixedly connected to the center of the inner sidewall of the protective top;
[0011] One end of the reinforcing column is welded to the fixing ring, and the other end of the reinforcing column is fixed to the support plate. At the same time, the upper side wall of the reinforcing column is fixedly connected to the inner wall of the protective top.
[0012] Furthermore, the number of the support plate and the reinforcing column is six sets, and the reinforcing column is evenly arranged radially on the fixing ring.
[0013] Furthermore, the outer wall of the protective roof is provided with a drip edge along its circumference.
[0014] Furthermore, a lower star-shaped frame is fixedly installed at the bottom of the reactor body, a mounting base is bolted to the bottom of the lower star-shaped frame, and a post insulator is fixedly connected to the bottom of the mounting base.
[0015] Furthermore, a shock-absorbing pad is fixedly installed on the top of the mounting base, the shock-absorbing pad being located between the lower star-shaped frame and the mounting base, and the number of post insulators is four sets.
[0016] Furthermore, a column is fixedly installed on the outer top of the protective roof, and three sets of reflective lenses are rotatably connected on the column. The three sets of reflective lenses are used to reflect light.
[0017] Compared with the prior art, the present invention has the following advantages:
[0018] By incorporating protective components, the corrosion of the reactor body by contaminants is reduced. The protective top can block rainwater and snowflakes from falling directly onto the top of the reactor body, reducing moisture corrosion. Simultaneously, the protective top also provides some protection against airborne debris such as branches and plastic bags, preventing them from contacting the reactor body and avoiding damage to the nano-coating or flashover caused by debris adhesion or impact. The auxiliary components enhance the stability of the protective top. The fixing ring and reinforcing column are fixedly connected to the inner wall of the protective top. Even in the face of strong winds or drastic weather changes, the protective top consistently performs its protective function, protecting the reactor body and preventing the penetration and corrosion of the reactor's multi-layered insulation film, thus ensuring the reliability and safety of the power grid operation.

Detailed Implementation
[0025] Specific Implementation Method 1: Combination Figures 1 to 4 This embodiment describes a pollution-resistant flashover dry-type hollow reactor based on a nano-coating, which includes a reactor body 1; it also includes a protection component 2 and an auxiliary component 3.
[0026] The protective component 2 is fixed to the top of the reactor body 1 by the auxiliary component 3;
[0027] The protective assembly 2 includes an upper star-shaped frame 201, a support block 202, a support plate 203, and a protective top 204; wherein, the upper star-shaped frame 201 is fixedly installed on the top of the reactor body 1; the support block 202 is bolted to the upper star-shaped frame 201, the support plate 203 is bolted to the support block 202, and the other end of the support plate 203 is fixedly connected to the protective top 204, which has a conical structure.
[0028] In this embodiment, such as Figure 4As shown, the protective assembly 2 includes an upper star-shaped frame 201 fixedly installed on the top of the reactor body 1. A support block 202 is bolted to the star-shaped frame, and a support plate 203 is bolted to the support block 202. A protective top 204 is fixedly connected to the other end of the support plate 203. The protective top 204 is located on one side of the reactor body 1. During use, the outer wall of the reactor body 1 is coated with a nano-coating, which reduces the possibility of flashover caused by surface moisture. The protective top 204 is located directly above the reactor body 1 and can block contaminants from above. In rainy or snowy weather conditions, the protective top 204 can prevent rainwater and snowflakes from falling directly onto the top of the reactor body 1, reducing the corrosion of the reactor body 1 by moisture. At the same time, the protective top 204 can also play a certain role in blocking some debris falling from the air, such as tree branches and plastic bags, preventing these debris from contacting the reactor body 1 and avoiding damage to the nano-coating on the reactor surface or flashover caused by debris adhesion or collision, thus providing protection for the reactor body 1.
[0029] Specific Implementation Method 2: This implementation method further defines the anti-pollution flashover dry hollow reactor based on nano-coating described in Specific Implementation Method 1. In this implementation method, the auxiliary component 3 includes a fixing ring 301 and a reinforcing column 302.
[0030] The fixing ring 301 is fixedly connected to the center of the inner sidewall of the protective top 204;
[0031] One end of the reinforcing column 302 is welded to the fixing ring 301, and the other end of the reinforcing column 302 is fixed to the support plate 203. At the same time, the upper side wall of the reinforcing column 302 is fixedly connected to the inner wall of the protective top 204.
[0032] In this embodiment, the auxiliary component 3 includes a fixing ring 301 fixedly connected to the inner wall of the protective top 204. A reinforcing column 302 is welded onto the fixing ring 301. The reinforcing column 302 is fixedly connected to the support plate 203 and the inner wall of the protective top 204. In use, the fixing ring 301 and the reinforcing column 302 are fixedly connected to the inner wall of the protective top 204, making the weight distribution of the protective top 204 more uniform. This allows the protective top 204 to better withstand external impact forces and weather pressure, improving the protective effect and enhancing the stability of the protective top 204. This ensures that the protective top 204 can consistently perform its protective function when facing strong winds or drastic weather changes, protecting the reactor body 1.
[0033] Specific Implementation Method 3: This implementation method further defines the anti-pollution flashover dry hollow reactor based on nano-coating described in Specific Implementation Method 2. In this implementation method, the number of the support plate 203 and the reinforcing column 302 is six sets, and the reinforcing column 302 is radially and uniformly arranged on the fixing ring 301.
[0034] In this embodiment, there are six sets of support plates 203 and reinforcing columns 302, which are radially and evenly arranged on the fixing ring 301. The radial and even arrangement of the reinforcing columns 302 on the fixing ring 301 reduces the risk of damage to the protective top 204, extends the service life of the protective top 204, and better protects the reactor body 1.
[0035] Specific Implementation Method Four: This implementation method further defines the anti-pollution flashover dry hollow reactor based on nano-coating described in Specific Implementation Method One. In this implementation method, the outer wall of the protective top 204 is provided with a drip edge 4 along its circumference.
[0036] In this embodiment, a drip edge 4 is bolted to the outer wall of the protective top 204, and the drip edge 4 is located on one side of the reactor body 1. In use, the drip edge 4 can effectively guide rainwater and snow water to the outside of the reactor body 1, preventing water droplets from contacting the surface of the reactor body 1, thereby reducing corrosion and flashover caused by water accumulation and enhancing the durability of the reactor body 1.
[0037] Specific Implementation Method Five: Combination Figure 5 This embodiment further defines the anti-pollution flashover dry-type hollow reactor based on nano-coating described in Specific Embodiment 1. In this embodiment, a lower star frame 5 is fixedly installed at the bottom of the reactor body 1, a mounting base 6 is bolted to the bottom of the lower star frame 5, and a post insulator 7 is fixedly connected to the bottom of the mounting base 6.
[0038] In this embodiment, a lower star-shaped frame 5 is fixedly installed at the bottom of the reactor body 1. A mounting base 6 is bolted to the bottom of the lower star-shaped frame 5, and a post insulator 7 is fixedly connected to the bottom of the mounting base 6. In use, the post insulator 7 insulates the reactor body 1 from the ground to prevent current leakage and ensures the safe operation of the reactor in a high-voltage environment.
[0039] Specific Implementation Method Six: This implementation method further defines the anti-pollution flashover dry-type hollow reactor based on nano-coating described in Specific Implementation Method Five. In this implementation method, a shock-absorbing pad 8 is fixedly provided on the top of the mounting base 6. The shock-absorbing pad 8 is located between the lower star frame 5 and the mounting base 6. The number of post insulators 7 is four sets.
[0040] In this embodiment, a shock-absorbing pad 8 is fixedly installed on the top of the mounting base 6. The shock-absorbing pad 8 is located between the lower star frame 5 and the mounting base 6, and there are four sets of post insulators 7. In use, the shock-absorbing pad 8 can effectively absorb and buffer the electromagnetic vibration generated by the reactor body 1 during operation, prevent the vibration energy from being directly transmitted to the post insulators 7, reduce noise, and extend the service life of the post insulators 7. The surface of the post insulators 7 is coated with a hydrophobic RTV anti-flashover coating, which effectively prevents equipment failure caused by insulator flashover.
[0041] Specific Implementation Method Seven: This implementation method further defines the anti-pollution flashover dry hollow reactor based on nano-coating described in Specific Implementation Method One. In this implementation method, a column 9 is fixedly installed on the outer side of the top of the protective top 204. Three sets of reflective mirrors 10 are rotatably connected on the column 9. The three sets of reflective mirrors 10 are used to reflect light.
[0042] In this embodiment, a column 9 is fixedly installed on the top of the protective top 204, and three sets of reflective lenses 10 are rotatably connected to the column 9. The three sets of reflective lenses 10 are located on one side of the protective top 204. In use, when there is wind, the three sets of reflective lenses 10 will rotate around the column 9. By reflecting light, the reflective lenses 10 can repel birds, effectively reducing the number of birds staying and moving near the reactor body 1, preventing birds from perching and defecating on or around the reactor body 1, thereby avoiding bird droppings from contaminating the surface of the reactor body 1 and the post insulator 7, and eliminating the risk of flashover.
[0043] Working Principle: This invention provides a flashover-resistant dry-type hollow reactor based on a nano-coating. During use: the outer wall of the reactor body 1 is coated with a nano-coating, reducing the possibility of flashover caused by surface moisture. The protective top 204 is located directly above the reactor body 1, blocking contaminants from above. The fixing ring 301 and the reinforcing column 302 are fixedly connected to the inner wall of the protective top 204, making the weight distribution of the protective top 204 more uniform. This allows the protective top 204 to better withstand external impact forces and weather pressure, improving the protective effect and enhancing the stability of the protective top 204. The drip edge 4 effectively guides rainwater and snowmelt to the outside of the reactor body 1, preventing water droplets from contacting the surface of the reactor body 1, thereby reducing corrosion and flashover caused by water accumulation. In windy conditions, three sets of reflective mirrors 10 rotate around the column 9, using the reflective mirrors 10 to reflect light and repel birds, effectively reducing birds' stay and activity near the reactor body 1.
