Description

Technical Field

[0001] The present invention relates to the technical field of substation equipment, and in particular to a substation box cleaning device for substation operation and maintenance and a use method thereof. Background Art

[0002] Pollution flashover of power equipment means that the porcelain surface of the equipment is contaminated by solid, liquid and gaseous conductive substances, which increases the conductivity of the insulation surface, increases the leakage current, and produces local discharge. Under the operating voltage, the local discharge on the surface of the insulation develops into arc flashover. This flashover is usually called pollution flashover.

[0003] The transformer box is a box in the power system where the voltage and current of electric energy are transformed, concentrated and distributed. During long-term use, a lot of dust will be deposited and attached to its outer surface. The dust will affect the heat dissipation capacity of the transformer box. It is also one of the power equipment most affected by flashover caused by environmental changes in recent years. Therefore, the transformer box needs to be cleaned of dust.

[0004] The traditional transformer box cleaning device for substation operation and maintenance requires workers to manually clean the surface of the transformer box. However, when cleaning, workers usually clean the four side walls of the transformer box in turn, which has low cleaning efficiency and high labor intensity for workers.

[0005] The U-shaped rod is then moved to one side of the transformer box body, and the transformer box body is located inside the U-shaped rod. The U-shaped rod is then closed, and the hook is hung on the hanging ring. The rotating motor is started, and the rotating motor can drive the pull rope provided with the hanging ring to be reeled in or lowered, thereby realizing the lifting and lowering of the U-shaped rod along the outer wall of the transformer box body. Since the inner wall of the U-shaped rod is provided with a cleaning brush, the cleaning brush can remove the dust attached to the outer surface of the transformer box body when the U-shaped rod is lifted and lowered, so as to prevent the dust from attaching to the transformer box body and affecting the transformer. Heat dissipation of the box body; or as disclosed in CN217726342U, CN107863711B and CN111112157B, similar means can be used to remove dust attached to the transformer box to prevent the transformer box from being disturbed by dust. However, none of the above solutions properly handles the dust generated when cleaning the transformer box and the large particles of impurities attached to the transformer box, resulting in poor cleaning effect of the transformer box, shortened cleaning cycle, and more maintenance times. In particular, there is a lack of dust treatment, so that after the transformer cabinet is cleaned, the dust gradually re-attaches to the transformer box, shortening the cleaning cycle of the transformer box and increasing the maintenance cost of the transformer box; at the same time, there is a lack of a storage structure for large particles of impurities. When the cleaning brush cleans the dust and large particles of impurities, they will fall around the transformer box, accelerating the deterioration of the environment around the transformer box, requiring staff to clean the large particles of impurities in the area around the transformer box, which is extremely cumbersome and inconvenient. Summary of the invention

[0006] The present invention provides a transformer box cleaning device and a use method for transformer operation and maintenance. A dust suction device is designed. When dust is generated by cleaning the transformer box with a brush, the dust is promptly processed by the dust suction device, thereby ensuring the transformer box cleaning effect. When large particles of impurities are cleaned, they will fall into the storage mechanism, thereby ensuring that the area around the transformer box is clean and tidy, and facilitating manual cleaning by later staff.

[0007] The object of the present invention is to provide a transformer box cleaning device and a method of use for transformer operation and maintenance, so as to solve the problems raised in the above-mentioned background technology.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0035] An embodiment provided by the present invention:

[0036] A substation box cleaning device for substation operation and maintenance comprises a substation cabinet body 1, brushes 2 are placed on the top of the substation cabinet body 1, two groups of moving mechanisms 3 are fixedly connected to the surfaces of four brushes 2, a group of top plates 4 are welded on the tops of the two moving mechanisms 3, dust suction mechanisms 5 are fixedly connected to the edges of the top of the substation cabinet body 1, through the arrangement of the brushes 2, the moving mechanisms 3 and the dust suction mechanisms 5, the moving mechanisms 3 are started to make the hydraulic rod drive the four brushes to clean the substation cabinet at the same time, so as to improve the efficiency of cleaning dust and reduce the labor intensity of the staff, storage mechanisms 6 are fixedly connected to the bottom of the substation cabinet body 1, and activated carbon 7 is placed inside the four storage mechanisms 6, and through the arrangement of the activated carbon 7 in the storage mechanisms 6, large particles of impurities cleaned from the substation cabinet body being cleaned are accommodated, so that it is convenient for the staff to uniformly handle the large particles of impurities later;

[0037] In addition to the activated carbon 7, other adsorbents can be placed in the storage mechanism 6. In order to select the adsorbent with the best adsorption capacity for large particle impurities among the different adsorbents stored in the storage mechanism 6, we conducted an adsorption experiment. To distinguish the adsorption capacity, we need to first understand the principle of adsorption: usually adsorption refers to a surface phenomenon. The larger the surface area of ​​the adsorbent, the greater the adsorption capacity. The types and preparation methods of the adsorbents are different, and their specific surface areas, particle sizes, pore structures and distributions are different, and the adsorption effects are also different. In addition, the surface chemical structure and surface charge properties of the adsorbent also have a great influence on the adsorption process. Polar molecular adsorbents are easy to adsorb polar molecular adsorbates, and non-polar molecular adsorbents are easy to adsorb non-polar molecular adsorbates. Activated carbon is a non-polar adsorbent, so when removing non-polar organic matter, it can avoid the adsorption sites being consumed by polar water molecules. A wet sponge has this effect. At the same time, the molecular size of the adsorbate also affects the adsorption rate. Generally, the smaller the molecular volume of the adsorbate, the greater its diffusion coefficient and the greater the adsorption rate. The adsorption process is usually an exothermic process, so the lower the temperature, the more favorable the adsorption is, especially in the case of physical adsorption. Since the adsorption operation is usually carried out at room temperature, the thermal effect of the adsorption process is small, and the temperature change is not obvious, so the temperature has little effect on the adsorption process. However, in the case of activated carbon regeneration, it is often heated to a large extent to desorb the adsorbate molecules. In summary, combined with the cost of the adsorption material, the adsorbent materials are respectively provided with activated carbon 7, sponge, quartz sand, acrylic cotton and coal slag, and a blank storage mechanism is set as a control group. The substation cabinet body 1 is cleaned for one month in the same environment of temperature, humidity and air pressure. During the cleaning process of the transformer cabinet body for one month, the coal slag performed well in terms of adsorption of large-particle impurities and cost control, but the coal slag would generate dust in a windy environment, resulting in the adsorption of coal slag on the transformer cabinet body 1, resulting in reduced cleaning efficiency and increased cleaning frequency, which is not the best material for the storage mechanism 6; when acrylic cotton is used as the adsorbent, it is too light and often flies out of the storage mechanism 6, resulting in reduced adsorption efficiency, which is not the best material for the storage mechanism 6; when quartz sand is used as the adsorbent, after a layer of large-particle impurities is adsorbed on the upper surface of the quartz sand, the adsorption efficiency decreases rapidly, which is not the best material for the storage mechanism 6; when sponge is used as the adsorbent, when the sponge is still in a wet state, the adsorption capacity for large-particle impurities is strong, and when the water on the sponge evaporates, the adsorption capacity for large-particle impurities decreases rapidly after the sponge becomes dry, which is not the best material for the storage mechanism 6; when activated carbon 7 is used as the adsorbent, it has a strong ability to adsorb large-particle impurities, a stable adsorption efficiency, and does not increase additional cleaning work, which is the best adsorbent for the storage mechanism 6; so activated carbon 7 is used.

[0038] like Figure 2As shown, the moving mechanism 3 includes two groups of receiving long plates 301 fixedly connected to the surfaces of four groups of brushes 2, the tops of the two receiving long plates 301 are fixedly connected with telescopic columns 302, and the middle parts of the top surfaces of the two receiving long plates 301 are integrally connected with hydraulic rods 303, and the hydraulic rods 303 play a role in driving the brushes 2 to move up and down, so as to facilitate the cleaning of dust on the outer surface of the transformer cabinet body 1.

[0039] like Figure 2 As shown, the dust collection mechanism 5 includes a dust collector 501 fixedly connected to the edges of both sides of the top of the transformer cabinet body 1, one side of the two dust collectors 501 is connected with a double-headed pipe 502, one side of the two double-headed pipes 502 is fixedly connected with four groups of dust collection heads 503, one side of the four dust collection heads 503 is fixedly connected to the other side of the supporting long board 301, and the dust collection heads 503 play a role in assisting the dust collector 501 to absorb dust in the air.

[0040] like Figure 3 As shown, the storage mechanism 6 includes a limit box 601 fixedly connected to the bottom of the transformer cabinet body 1, the interiors of the four limit boxes 601 are placed outside the activated carbon 7, one end of the inner wall of the four limit boxes 601 is fixedly connected with a groove plate 602, and the other end of the inner wall of the four limit boxes 601 is provided with a card slot, and the inside of the four card slots is snap-connected with a partition 603, which plays a role in protecting the activated carbon 7.

[0041] like Figure 4 As shown, three sets of cabinet doors 8 are rotatably connected to the front of the transformer cabinet body 1 , and handles 9 are fixedly connected to the front of the three cabinet doors 8 , and the handles 9 serve to open the cabinet doors 8 .

[0042] like Figure 1 As shown, two groups of receiving plates 10 are welded to the inner bottom wall of the top plate 4, and the bottoms of the two receiving plates 10 are integrally connected with supporting legs 11, and the bottoms of the two supporting legs 11 are fixedly connected to the left and right sides of the top of the transformer cabinet body 1, and the supporting legs 11 play the role of supporting the top plate 4.

[0043] like Figure 3 As shown, one side of the four partitions 603 is integrally connected with a handle 12, and the surfaces of the four handles 12 are sleeved with anti-slip covers to prevent the hands from slipping.

[0044] The working steps of the transformer box cleaning device for transformer operation and maintenance are as follows:

[0045] S1. Before removing dust, the four groups of partitions (603) are pulled out and separated from the four groups of limit boxes (601), so that the storage mechanism (5) starts to work;

[0046] S2, starting the hydraulic rod (303), which drives the brush (2) to move up and down under the action of the supporting long board (301) and the telescopic column (302);

[0047] S2, the power is turned on, the vacuum cleaner (501) is started, and the vacuum head (503) moves up and down with the hydraulic rod (303), and absorbs the dust stirred up by the brush (2) in the air. At the same time, large particles of impurities fall onto the surface of the four groups of activated carbon (7) due to their own gravity, and the four groups of activated carbon (7) absorb and fix the large particles of impurities.

[0048] Working principle: Before removing dust, pull out the four groups of partitions 603 and separate them from the four groups of limit boxes 601 to expose the four groups of activated carbon 7, and start the hydraulic rod 303. Under the action of the long plate 301 and the telescopic column 302, the hydraulic rod 303 drives the brush 2 to move up and down, thereby removing the dust adhered to the outer surface of the transformer cabinet body 1. When the power is turned on, the vacuum cleaner 501 is started to make the vacuum head 503 generate suction. The vacuum head 503 moves up and down with the hydraulic rod 303 to absorb the dust stirred up by the brush 2 in the air. When the brush 2 removes the dust on the outer surface of the transformer cabinet body 1, large particles of impurities will fall to the surface of the four groups of activated carbon 7 due to their own gravity, and the four groups of activated carbon 7 will absorb and fix the large particles of impurities.
