Abstract
Description
Technical Field
[0001] The invention relates to the technical field of insulator contamination analysis in a power system, and in particular to an ultrasonic insulator contamination constant volume analysis system. Background Art
[0002] At present, when the laboratory conducts volumetric analysis of insulator contamination, it often simply distinguishes the salt and ash in the contamination by dissolving and filtering the insulator contamination; salt refers to the general term for soluble components in the contamination; ash refers to the general term for insoluble components in the contamination. Then, for the soluble contamination (salt) part, by preparing a NaCl solution with the same conductivity as the salt solution, the content of dissolved NaCl is used to characterize the content of soluble contamination; for the insoluble contamination part (ash), it needs to be sent to a special testing agency for analysis of its composition, etc.
[0003] In this process, the process of promoting the mixing of pollutants and water by artificially controlling the stirring of glass rods is highly random, which greatly reduces the accuracy of measuring the salt content of pollutants. As for ash, it is not enough to simply separate and analyze it as a whole. Ash of different particle sizes affects the performance and surface characteristics of insulators, and will cause differences in local conductivity, dielectric constant, and surface electric field distribution on the surface of insulators. In addition, the filtration method used in the laboratory can only process a small amount of turbid liquid each time, and the processing efficiency is also relatively limited.
[0004] In summary, the existing insulator contamination separation and analysis methods have limitations and shortcomings: there are problems such as inaccurate, insufficient and low efficiency in the separation process, and the influence of ash of different particle sizes is not considered in the analysis process. Summary of the invention
[0005] In view of the shortcomings of the existing pollution volume analysis method, the present invention provides an ultrasonic insulator pollution volume analysis system, which controls the ultrasonic frequency and the multi-stage sedimentation table to accurately and efficiently separate the salt and ash while achieving the separation of ash by particle size.

[0010] Furthermore, the stirring motor of the stirring and mixing device is connected to a speed controller, and the speed controller is used to adjust the speed of the suspended blades according to demand to obtain a mixture of insulator contaminants and water with different stirring degrees.
[0011] Furthermore, each sedimentation container is provided with a sedimentation tank at the bottom, through which the suspension is discharged into the sedimentation container of the next stage while retaining the settled ash particles in the current stage without loss.
[0012] Furthermore, the stirring and mixing device stirs and mixes the water containing the insulator contaminants through suspended blades, so that the mixed water consisting of the insulator contaminants and water is changed from a disordered mixture to a suspension in which the soluble contaminants are fully dissolved and the insoluble contaminants are evenly distributed.
[0013] Furthermore, the ultrasonic multi-stage sedimentation device controls the ultrasonic generating base at the bottom of each sedimentation container to output ultrasonic signals of different frequencies through an ultrasonic frequency gear controller, thereby controlling the sedimentation of ash particles of different particle sizes in each sedimentation container to obtain a quasi-clarified solution with or without a small amount of tiny insoluble impurities; The sedimentation container includes a primary sedimentation container, a secondary sedimentation container and a tertiary sedimentation container; the ultrasonic generating base at the bottom of the primary sedimentation container adjusts the ultrasonic frequency to 20kHz and precipitates ash particles with a particle size greater than 100μm; the ultrasonic generating base at the bottom of the secondary sedimentation container adjusts the ultrasonic frequency to 50kHz and precipitates ash particles with a particle size of 10-100μm; the ultrasonic generating base at the bottom of the tertiary sedimentation container adjusts the ultrasonic frequency to 100kHz and precipitates ash particles with a particle size less than 10μm.
[0014] Furthermore, the automatic filtering device controls the flow rate of the liquid to flow through the multiple filter layers arranged sequentially from high to low inside, thereby obtaining a salt solution free of insoluble ash.
[0015] Furthermore, the constant volume analysis device transports the salt solution in the salt container to the constant volume analyzer through a suction pump, and at the same time transports the ash of different particle size grades on each level of sedimentation containers and each filter layer of the automatic filtration device to the constant volume analyzer through a suction pump for constant volume analysis.
[0016] The beneficial effects of the present invention are: The present invention realizes the rapid mixing of insulator contaminants and water through a sufficient and efficient stirring and mixing device, accelerates the full dissolution of soluble contaminants, and allows the suspension to enter the ultrasonic multi-stage sedimentation device evenly through a gradient water channel. The ultrasonic multi-stage sedimentation device is provided with a multi-stage sedimentation container, and cooperates with ultrasonic generating bases of different frequencies to realize the separation of ash by particle size, and cooperates with the automatic filtering device to collect tiny ash particles by multi-layer filtration, so as to obtain the content and proportion of ash in different particle size ranges in the insulator contaminants. In the process of insulator contamination analysis, the influencing factor of the contaminant particle size is added, making the analysis of insulator contamination more comprehensive and clear.
[0017] In summary, the insulator contamination constant volume analysis system based on ultrasound and multi-stage sedimentation system avoids the problems of insufficient salt dissolution, rough ash separation, cumbersome processing process and low processing efficiency in traditional separation and analysis methods, and realizes accurate and efficient separation and analysis of insulator contamination. It also takes into account the particle size of insoluble contamination, enriches the analysis angle of insulator contamination, and helps to obtain more comprehensive and accurate analysis results.

DETAILED DESCRIPTION
[0020] The following will be combined with the drawings of the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without creative work are within the scope of protection of the present invention.
[0021] This embodiment provides an ultrasonic insulator contamination constant volume analysis system, such as Figure 1 As shown, the ultrasonic insulator contamination constant volume analysis system includes a main frame, and components such as a stirring and mixing device 1, an ultrasonic multi-stage sedimentation device 2, an automatic filtering device 3, a constant volume analysis device 4, a valve automatic control device and a connecting pipeline located in the main frame; the specific structure and connection relationship of the above components are as follows: Stirring and mixing device 1: like Figure 1 and Figure 2As shown, the stirring and mixing device 1 includes a stirring container 5, a stirring motor 6 installed at the bottom of the stirring container 5, and a suspension blade 7 located in the stirring container 5 and installed on the output shaft of the stirring motor 6. The suspension blade 7 is used to stir the water body with insulator contaminants to make it fully mixed. One side of the stirring container 5 is connected to the contaminant inlet 27 and the water inlet 28, and the other side is connected to the ultrasonic multi-stage sedimentation device 2 through a pipeline.
[0022] Ultrasonic multi-stage sedimentation device 2: like Figure 1 As shown, the ultrasonic multi-stage sedimentation system consists of three sedimentation containers 8, an ultrasonic generating base 9 and an ultrasonic frequency gear controller 10. An ultrasonic generating base 9 is installed at the bottom of each sedimentation container 8, and an ultrasonic generator is installed in the ultrasonic generating base 9. The ultrasonic generator is connected to the ultrasonic frequency gear controller 10 by wire. The three sedimentation containers 8 are connected in sequence through pipelines. The sedimentation container 8 on the right side of the three sedimentation containers 8 is connected to the stirring container 5 through a pipeline, and the sedimentation container 8 on the left side is connected to the automatic filtering device 3 through a pipeline.
[0023] The ultrasonic frequency gear controller 10 controls the ultrasonic generating base 9 at the bottom of each sedimentation container 8 to output ultrasonic signals of different frequencies, and the frequency of the ultrasonic generating base 9 corresponding to each sedimentation container 8 is independent.
[0024] Automatic filtering device 3: like Figure 1 and Figure 3 As shown, the automatic filtering device 3 is a filter, in which multiple filter layers 11 are arranged in sequence from high to low; an inlet is formed on one side of the automatic filtering device 3, and the inlet is connected to the sedimentation container 8 through a pipeline; a discharge port is formed at the bottom of the automatic filtering device 3, and the discharge port is connected to the salt container 12.
[0025] Valve automatic control device and connecting pipeline: like Figure 1 As shown, the connecting pipeline includes a first pipeline 15 located between the stirring container 5 and the sedimentation container 8 , a second pipeline 16 located between the automatic filtering device 3 and the sedimentation container 8 , and a third pipeline 17 and a fourth pipeline 18 between each sedimentation container 8 .
[0026] like Figure 1As shown, the valve automatic control device includes a first electrically-controlled valve 19 and a second electrically-controlled valve 20 arranged on both sides of the first pipeline 15, a third electrically-controlled valve 21 arranged on the second pipeline 16, and a fourth electrically-controlled valve 22 and a fifth electrically-controlled valve 23 arranged on the third pipeline 17 and the fourth pipeline 18; wherein the first electrically-controlled valve 19, the second electrically-controlled valve 20, the third electrically-controlled valve 21, the fourth electrically-controlled valve 22 and the fifth electrically-controlled valve 23 are all connected to the PLC programmable controller 24.
[0027] Each water inlet and outlet is controlled by the valve automatic control device in conjunction with the connecting pipeline, so that each water inlet and outlet can be automatically opened and closed; thereby ensuring that the stirring and mixing device 1, each sedimentation container 8 of the ultrasonic multi-stage sedimentation device 2, and the automatic filtering device 3 work independently, and the inlet and outlet channels of the device are sealed when the corresponding work is not completed.
[0028] Constant volume analysis device 4: like Figure 1 and Figure 4 As shown, the constant volume analysis device 4 includes a constant volume analyzer, which is respectively connected to the salt container 12, three sedimentation containers 8 and the automatic filtering device 3 through multiple suction pipelines 13, and each suction pipeline 13 is provided with a suction pump 14.
[0029] The specific functions of each component of the ultrasonic insulator contamination constant volume analysis system are as follows: Stirring and mixing device 1: The stirring and mixing device 1 stirs and mixes the water body containing insulator contaminants through the suspended blades 7, so that the mixed water body composed of insulator contaminants and water is changed from a chaotic mixture to a suspension in which soluble contaminants are fully dissolved and insoluble contaminants are evenly distributed, ready for sedimentation and use.
[0030] Ultrasonic multi-stage sedimentation device 2: Ultrasonic multi-stage sedimentation device 2 is used to separate ash particles of different particle sizes. Since the weights of ash particles of different particle sizes are different, the results of whether they are precipitated are also different under different ultrasonic frequencies. Based on this, the ultrasonic frequency gear controller 10 controls the ultrasonic generating base 9 at the bottom of each sedimentation container 8 to output ultrasonic signals of different frequencies, thereby controlling the sedimentation of ash particles of different particle sizes in each level of sedimentation container 8. In operation, the ultrasonic frequency gear controller 10 can be used to adjust the ultrasonic frequency based on the preset particle size range of each level of separation. It should be noted that during sedimentation, the suspension located at the upper part of the sedimentation container 8 should be introduced into the next level sedimentation container 8 for the next level of sedimentation after the sedimentation of the previous level. After the suspension has been sedimented step by step, the original insoluble dirt components in it are almost gone, and the remaining liquid is a quasi-clear solution with no or a small amount of tiny insoluble dirt.
[0031] Automatic filtering device 3: The automatic filtering device 3 is used to process quasi-clear solutions. By controlling the liquid flow rate to flow through the multiple filter layers 11 arranged in sequence from high to low inside, the final insoluble tiny particles can be collected and a solution of soluble impurities can be obtained, that is, a salt solution free of insoluble ash is obtained; the salt solution free of insoluble ash flows from the automatic filtering device 3 into the salt container 12.
[0032] Constant volume analysis device 4: The constant volume analysis device 4 can transport the salt solution in the salt container 12 to the constant volume analyzer through the suction pump 14, and at the same time transport the ash of different particle size grades on the sedimentation containers 8 at each level and the filtration layers 11 of the automatic filtration device 3 to the constant volume analyzer for analysis.
[0033] Further, as a preferred technical solution of this embodiment, Figure 1 As shown, the stirring motor 6 of the stirring and mixing device 1 is connected to a speed controller 25, and the speed controller 25 can adjust the speed of the suspension blade 7 as required to obtain a mixture of insulator contaminants and water with different stirring degrees.
[0034] Further, as a preferred technical solution of this embodiment, Figure 1 As shown, in this embodiment, the first pipeline 15 connecting the stirring container 5 and the ultrasonic multi-stage sedimentation device 2 adopts a gradient pipeline, the large diameter side of the gradient pipeline is connected to the stirring container 5, and the small diameter side is connected to the ultrasonic multi-stage sedimentation device 2; by adopting the gradient pipeline, it can be ensured that the suspension containing insoluble pollutants maintains a uniform distribution of insoluble substances in the waterway.
[0035] Further, as a preferred technical solution of this embodiment, Figure 1 As shown, in this embodiment, each sedimentation container 8 is provided with a sedimentation tank 26 at the bottom, which is conducive to retaining the settled ash particles in the current stage without loss while the suspension is discharged into the next-stage sedimentation container 8.
[0036] Based on the above structure, the working principle of the ultrasonic insulator contamination constant volume analysis system is as follows: First, a certain amount of insulator dirt is hung from the insulator and sent into the stirring container 5 through the dirt inlet 27, and a certain amount of water is injected into the stirring container 5 through the water inlet 28; at this time, the stirring motor 6 is started, and the water body containing the insulator dirt is stirred and mixed by the suspended blades 7, so that the mixed water body composed of the insulator dirt and water is changed from a chaotic mixture to a suspension in which the soluble dirt is fully dissolved and the insoluble dirt is evenly distributed.
[0037] Then, the first electrically controlled valve 19 and the second electrically controlled valve 20 on the first pipeline 15 between the stirring container 5 and the sedimentation container 8 are opened through the PLC programmable controller 24, so that the suspension enters the first sedimentation container 8 on the leftmost side of the three sedimentation containers 8. After the suspension enters, the first electrically controlled valve 19 and the second electrically controlled valve 20 are closed, and the stirring and mixing device 1 can start the next suspension mixing work. At the same time, the ultrasonic frequency gear controller 10 starts the ultrasonic generating base 9 at the bottom of the first sedimentation container 8, and adjusts the ultrasonic frequency to 20kHz, and the suspension is oscillated at the ultrasonic frequency of 20kHz. After a period of time, particles with a particle size greater than 100μm are settled to the sedimentation tank 26 at the bottom of the first sedimentation container 8; after the first sedimentation is sufficient, the four electrically controlled valves on the third pipeline 17 are opened through the PLC programmable controller 24, so that the suspension in the upper part of the first sedimentation container 8 is discharged into the second sedimentation container 8.
[0038] After the suspension is discharged into the secondary sedimentation container 8, the fourth electrically-controlled valve 22 is closed, and at the same time, the ultrasonic generating base 9 at the bottom of the secondary sedimentation container 8 is started through the ultrasonic frequency gear controller 10, and the ultrasonic frequency is adjusted to 50kHz. The suspension is oscillated at an ultrasonic frequency of 50kHz. After a period of time, particles with a particle size greater than 10-100μm are settled to the sedimentation tank 26 at the bottom of the secondary sedimentation container 8; after the secondary sedimentation is sufficient, the five electrically-controlled valves on the fourth pipeline 18 are opened through the PLC programmable controller 24, so that the suspension in the upper part of the secondary sedimentation container 8 is discharged into the tertiary sedimentation container 8.
[0039] After the suspension is discharged into the tertiary sedimentation container 8, the fifth electrically-controlled valve 23 is closed, and at the same time, the ultrasonic generating base 9 at the bottom of the tertiary sedimentation container 8 is started through the ultrasonic frequency gear controller 10, and the ultrasonic frequency is adjusted to 100kHz, and the suspension is oscillated at the ultrasonic frequency of 100kHz. After a period of time, particles with a particle size of less than 10μm are settled to the sedimentation tank 26 at the bottom of the tertiary sedimentation container 8; after the suspension is gradually settled, the original insoluble impurity components in it are almost gone, and the remaining liquid is a quasi-clear solution with no or a small amount of tiny insoluble impurities. After the tertiary sedimentation is sufficient, the third electrically-controlled valve 21 on the second pipeline 16 between the automatic filtering device 3 and the sedimentation container 8 is opened through the PLC programmable controller 24, so that the quasi-clear solution in the upper part of the tertiary sedimentation container 8 enters the automatic filtering device 3.
[0040] The flow rate of the quasi-clarified solution is controlled by the third electrically controlled valve 21. After the quasi-clarified solution passes through the multiple filter layers 11 arranged in order from high to low in the automatic filtering device 3, the saline solution without insoluble ash flows into the saline container 12. At this time, the constant volume analysis device 4 transports the saline solution in the saline container 12 to the constant volume analyzer through the suction pump 14, and at the same time transports the ash of different particle size grades on the sedimentation containers 8 at each level and the filter layers 11 of the automatic filtering device 3 to the constant volume analyzer, thereby completing the separation and constant volume analysis of the insulator contaminants.
[0041] In summary, through the sufficient and efficient stirring and mixing device 1, the rapid mixing of insulator contaminants and water is achieved, the full dissolution of soluble contaminants is accelerated, and the suspension can be uniformly entered into the ultrasonic multi-stage sedimentation device 2 through the gradient water channel. The ultrasonic multi-stage sedimentation device 2 is provided with a multi-stage sedimentation container 8, and cooperates with an ultrasonic generating base 9 of different frequencies to realize the separation of ash by particle size, and cooperates with the automatic filtering device 3 to collect tiny ash particles by multi-layer filtration, so as to obtain the content and proportion of ash in different particle size ranges in the insulator contaminants. In the process of insulator contamination analysis, the influencing factor of the contaminant particle size is added, making the analysis of insulator contamination more comprehensive and clear.
[0042] The insulator contamination constant volume analysis system based on ultrasound and multi-stage sedimentation system avoids the problems of insufficient salt dissolution, rough ash separation, cumbersome processing process and low processing efficiency in traditional separation and analysis methods, and realizes accurate and efficient separation and analysis of insulator contamination. It also takes into account the particle size of insoluble contamination, enriches the analysis angle of insulator contamination, and helps to obtain more comprehensive and accurate analysis results.
[0043] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
