Description

Anti-fouling flash paint spraying equipment

technical field

The utility model relates to the technical field of anti-pollution flashover of power transmission lines, in particular to an anti-pollution flashover paint spraying equipment.

Background technique

Pollution flashover refers to the phenomenon that the soluble substances of the dirt attached to the insulating surface of electrical equipment gradually dissolve in water under humid conditions, forming a conductive film on the insulating surface, which greatly reduces the insulation level of the insulator, and occurs under the action of an electric field. Strong discharge phenomenon. There are many anti-fouling flashover measures. The traditional method is power outage cleaning in spring and autumn. The more advanced method is to use anti-fouling flashover coatings such as silicone rubber to form a protective coating of anti-fouling flashover coatings on the insulating surface of electrical equipment.

The antifouling flashover coating is preferably liquid silicone rubber, which has unique electrical and physical and chemical properties, and is specially used for hydrophobic modification and substantial protection of the outer insulating surface of power transmission and transformation equipment.

In order to facilitate the application of different site conditions, different workpiece shapes and other application conditions, in the coating manufacturing process, the ends of the molecular chains are sealed with special cross-linking agents to produce liquid coatings. The liquid silicone rubber will react with the water molecules in the air at the moment of spraying on site, and the cured silicone rubber elastic film after the solvent is removed can be formed on the spot according to the shape of the workpiece, thus becoming a silicone rubber protective coating with the ability to prevent pollution flashover and wet flashover , and run with the equipment in the outdoor environment for a long time.

Antifouling flashover coatings mainly have the following characteristics:

①Paint viscosity is special: Anti-pollution flash silicone rubber coating has high viscosity. Compared with the previous version, the latest industry standard DL/T627-2010 has added viscosity terms (see 4.1.3 viscosity of DL/T627-2010), and the requirements are in accordance with GB -T1723-1993 "Measurement of Coating Viscosity", the test method of Tu-4 viscometer is not less than 80s, which is 3000 times that of water under the same conditions, and the viscosity is much higher than that of traditional water-based paints. The architectural paints, anti-corrosion paints, Home improvement paints are all water-based paints.

② Special vulcanization of coatings: Different from traditional water-based coatings, silicone rubber is a chemical process from coating to coating. In order to facilitate on-site molding, the anti-fouling flash silicone rubber is specially made into a liquid state by blocking the reaction, and the final vulcanization reaction is realized during spraying: the easily hydrolyzed functional groups in the liquid silicone rubber fully absorb the water molecules in the air, and the hydrogen in the water molecules Combined with organic silicon, the low-molecular special solvent is released, and the hydroxyl group combined with the hydrogen group of water molecules moves to the molecular position originally blocked by the special solvent, forming a cross-linked structure with silicone, and completing spraying-hydrolysis-polycondensation and curing to form an elastic film the process of.

③The workpiece to be coated is special: the anti-fouling flash silicone rubber is a coating based on porcelain and glass, which is used for the external insulation of power transmission and transformation equipment. , the upper and lower sheds with different diameters are arranged staggered, the distance between the upper and lower sheds is small, the lower edge of the umbrella is difficult to touch, and the inside of the umbrella is difficult to touch regardless of the upper and lower edges; the suspension insulator of the transmission line is equivalent to the external insulation of the substation equipment , but the spacing between the umbrella pieces is slightly larger, while the umbrella pieces of the tension insulator are vertical to the ground, making it more difficult for the paint to adhere.

④Special coating operation: except for specific electrical properties, hydrophobic properties, etc., it can be seen only from the coating operating environment and the specified 8-year and 15-year life requirements. The requirements for density and other aspects are very high, otherwise it is difficult to withstand the long-term field physical, chemical, biological and other natural environmental impacts and human factors in the maintenance process.

To sum up, the characteristics of anti-pollution flashover coatings require professional spraying equipment and processes, which are suitable for spraying silicone rubber coatings.

The construction of anti-pollution flashover coating is relatively difficult. In the construction process of transmission lines that generally require trekking across mountains and rivers, the entire line must be cut off at the same time, and the power outage time is strictly limited, there are two important particularities that affect the spraying. construction:

First, it is difficult to carry. Under the conditions of transport, the total weight of basic construction materials such as spraying equipment, pipelines, spray guns, paints, cleaning agents, power fuels, personal safety tools, necessary maintenance tools, first aid items, and food is large. , The transportation cost and time cost are much greater than the actual spraying operation, and the construction of the transmission line must be the construction of the entire line without power.

Second, there is no power supply. The transmission line is operated in the field and there is no power supply. Therefore, electric equipment is not available, or additional power generation equipment is required. During the construction of the line, transportation and handling are huge obstacles, and an additional generator is added for each base tower. make construction more difficult.

In the prior art, there are mainly the following methods for forming an anti-pollution flashover paint protective coating on the outer insulating surface of power transmission and transformation equipment:

①Air spraying

Whether it is in a power transformation system (such as a substation) or a power transmission system (such as a line), in the occasions and conditions where spraying can be carried out, air spraying equipment and processes are mainly used, that is, diesel air compressors, air filter tanks, and air pipes. And an air spray gun with watering can.

Diesel air compressors and air filter tanks are large in size, heavy in weight, loud in noise, large in gas output and high in pressure.

On the one hand, in terms of technology, air spraying has lagged behind, and it is not suitable for spraying anti-fouling flash coatings. Air spray guns are traditionally used for spraying water-based paints such as architectural coatings, anti-corrosion coatings, and home improvement paints. The high-pressure compressed air of 0.8Mp rushes out from the nozzle of the spray gun at a high flow rate of 10m/s, so that a partial vacuum is formed around the nozzle due to negative pressure. The paint is sucked into the vacuum space by the compressed air, and the paint meets the released compressed air and is smashed and atomized, and is brought to the surface of the insulator in a flat fan shape by the airflow according to the shape of the nozzle. The air pressure is large, the output is large, and the output The particles are also large, and the insufficient atomization leads to insufficient vulcanization of the silicone rubber coating, which aggravates the adverse effects of the long drying time and curing time of the coating. The insufficiently vulcanized front layer means that there is still solution that has not been removed, and the back layer continues to cover When it lacks adhesion, it is prone to accumulation and flow. If you want to avoid accumulation and flow, you can only sacrifice the thickness, and you can't continue spraying.

Since the paint system follows the airflow and falls on the surface of the insulator due to resistance, the adhesion of the final coating is weak.

At the same time, there are no control measures for the fan-shaped atomized paint brought out by the airflow. In addition, the nozzle diameter of Φ2.5mm is large and the spray angle is large. In addition to being directly scattered on both sides of the insulator, the atomized paint with high impact is rebounded and atomized when it encounters the insulator. The paint also has no control measures, and it scatters around in the shape of a shallow pot. Therefore, not only the pollution (pollution of non-sprayed parts, air pollution, ground pollution, and health damage to personnel) is large, but also the actual loss of the paint site is large. )Low.

In addition, due to the limitation of the holding force, the watering can has limited material, 1-1.5L, and frequent feeding up and down will not only affect the construction progress, but also increase the labor cost.

On the other hand, air spraying equipment is heavy and difficult to carry, so it is not suitable for power transmission line construction. A single set of diesel air compressor and air filter tank weighs hundreds of kilograms. It is impossible to climb mountains and mountains by manpower. Even if it is a transportable line, the manpower, material resources and time of handling far exceed the cost of spraying.

If each base tower is equipped with several small electric air compressors, but there is no power supply, each base tower must be equipped with a generator separately, the total weight is still very large, and the transportation cost is still very high.

② Very few use high-pressure airless spraying

During the spraying process, it is necessary to use an electric high-pressure pump, a high-pressure material pipe and a high-pressure airless spray gun as shown in Figure 1. Figure 2 shows the atomized anti-fouling flashover coating sprayed by a high-pressure airless spray gun.

The spraying device composed of the above components is small in size, light in weight, and has pressure on the paint.

The reason why this equipment can only be seen in very rare occasions is that the purchase cost and maintenance cost are relatively high, and the equipment with only one spray gun is too scattered.

On the power transmission line, there is no power supply, or a generator must be equipped. According to the calculation of three spraying machines in one base tower, the total weight and cost of handling after the generator is equipped are still very high.

③Brush by hand

Under the condition that it cannot be transported or is difficult to transport, spraying can only be given up and manual brushing is used, and the characteristics of silicone rubber coating are not suitable for manual brushing. Since silicone rubber is a chemical process from coating to coating, the vulcanization must be applied thinly and the vulcanization time must be given, so each brush has less adhesion and repeated brushing many times. The paint finger dry time indicator shows that finger dry takes time. If you wait for the front layer to dry before repainting, the work cannot be completed during the power outage; if the front layer does not reach the finger dry and repeat brushing, the brush and paint will pull and damage the front coating, and the coating surface will not be fully Uneven lumps and brush marks are formed due to vulcanization, and the rough and uneven surface is more likely to accumulate dirt. Not only is the construction speed slow, but it is also difficult to achieve the specified thickness, and the coating quality cannot meet the anti-fouling flashover ability.

The reason why many lines are still allowed to be painted by hand is due to the urgent requirement that the external insulation equipment must be protected to prevent flashover accidents.

At the same time, the air curtain can also provide a driving force for the anti-fouling flashover coating, so that the anti-fouling flashover coating can be sprayed more powerfully and deeply to various positions on the surface of the sprayed workpiece. Therefore, the drifting paint mist is small, the pollution is small, the paint loss is small and the utilization rate of the paint (that is, the adhesion rate of the paint) is high, and the coating surface is more uniform, dense, smooth and strong in adhesion;

Compared with the prior art, the preferred technical solution of the utility model can also produce the following technical effects:

①A more effective and professional spraying method is adopted for the anti-pollution flashover coating with special performance and application.

The high-pressure diaphragm pump is used to pressurize the paint itself to a working pressure of 4-8MPa and then release it. The atomization ability and effect of the paint are remarkable. The atomized paint under pressure is pressed on the surface of the insulator layer by layer, with strong adhesion. The 2.4L/min flow rate of the high-pressure diaphragm pump supports three spray guns, which can be combined flexibly and realize ground loading. The rated pressure of 25MPa makes it possible to spray at a height of 120 meters.

Using a high-pressure auxiliary air spray gun, the pressurized paint is released flat on the elephant-eye-shaped gun nozzle with an equal circle diameter of 0.33mm, flow rate and width adjustable. The released paint is atomized into an aerosol with a particle size of 0.2μm due to expansion, ensuring At the moment of release, the coating can fully vulcanize and react with the water molecules in the air with the largest area and volume, and quickly remove the solvent. At the same time, the flow rate of 0.5L/min of the spray gun makes the protective coating of anti-pollution flashover coating (coating for short) sprayed every time It is controlled to be very thin, and the finger drying time is shortened by the spray gun. When spraying layer by layer for multiple times, the anti-fouling flashover coating is not easy to accumulate and flow. This kind of polycondensation is formed by the sprayer controlled by the equipment and process, which can only be sprayed layer by layer multiple times. The surface of the cured coating is uniform, dense, smooth and has strong adhesion.

The air compression pump is used to match the high-pressure auxiliary air spray gun with a low-pressure auxiliary air system with a working pressure of 0.2-0.3MPa, which again assists the atomization of the paint released by the nozzle to achieve twin atomization, and the atomization effect is more ideal. At the same time, Constructed with 10 (the specific number can be set as less or more according to the needs) spray gun hood with spiral channels, the vortex-rotating circulation air curtain sprays out the atomized paint and sprays it to the workpiece in a flat flame shape, and penetrates into various positions , Therefore, the drifting paint aerosol is small, the pollution is small, the paint loss is small, the paint adhesion rate (that is, the paint utilization rate) is high, and the surface of the protective coating on each part of the insulator is smooth and uniform. The configuration of the air compressor pump makes it possible to use the high-pressure auxiliary air spray gun. If there is no air compressor pump, even if a high-pressure diaphragm pump is used, it can only match the high-pressure airless spray gun. The quality and effect of the high-pressure airless spraying still cannot reach the high-pressure auxiliary air The degree of spraying. The high-altitude operation of the transmission line itself has a strong wind force, coupled with the vertical suspension of the umbrella skirt, it is inevitable that the package without auxiliary air will flow and drip. The sprayed material is granular and the surface is uneven and not smooth. In addition, the construction speed and paint utilization rate will be affected. In particular, the adoption of sliding vane compression technology avoids the installation of an air storage tank. The flow rate of 0.24m ³ /min can continuously supply air to three spray guns, and the safety valve can automatically discharge excess compressed air.

From the perspective of pure spraying technology, the high-pressure auxiliary air spraying method provided by the embodiment of the utility model has changed the history of air spraying equipment and technology that also uses water-based coatings for anti-fouling flashover coatings, so that the anti-fouling flashover coatings have appropriate and professional Spraying equipment and processes.

② The power and spraying integrated system makes the power transmission and transformation spraying construction not limited by the power source.

At present, any spraying equipment needs to be equipped with additional power, including electric air compressors and diesel-powered air compressors. Under the condition that there is no power supply on the transmission line, and the generator and diesel air compressors are difficult to transport, the power becomes whether the construction and The key to the smooth construction.

A general-purpose engine is used to drive the high-pressure diaphragm pump and the air compressor pump to achieve integration, so that the spraying of anti-fouling flashover coatings is not restricted by the construction environment. Whether it is a substation or a line, when there is a lack of power supply or it is difficult to connect to the power supply, it can be completed under self-control. construction tasks.

③Light and simple equipment is easy to carry

Not only the four wheels are movable, but also light in weight and easy to carry, even the three parts of the main equipment (the three parts are the diaphragm pump, the air compressor pump and the engine) can be disassembled and carried, making spraying construction possible in any occasion.

④Reduce construction cost, improve labor productivity, especially reduce potential safety hazards

From the perspective of equipment, one equipment is connected with three spray guns, the production capacity of a single equipment itself is doubled, and the purchase cost is reduced.

From the construction point of view, the transportation and handling costs are reduced; the paint does not need to be passed up and down for replacement, saving labor costs, and the construction speed is fast and the efficiency is high. Overall labor productivity is improved. From a more important safety point of view, when working in a high-risk environment such as power transmission and transformation, fewer links, simpler equipment, and easier construction reduce the potential safety hazards in long-distance transportation, entry and exit, and spraying, and improve It meets the conditions of safe production and is more in line with the production policy of safety first.
