Description

Technical Field

[0001] The invention relates to the technical field of insulator pollution collection in a power system, and in particular to an insulator pollution collection method based on a rapid collection device. Background Art

[0002] With the continuous development of the power system, its safe and stable operation has received more and more attention. Insulators, as important components that play the role of mechanical connection support and electrical insulation for electrical equipment, are an indispensable part of the power system. The insulation performance of insulators directly affects whether the power system can maintain stable operation, and its contamination problem has become one of the key factors affecting the stability of power system operation. When the insulator is contaminated, due to the distortion of the electric field and the uneven distribution of leakage current in different areas of the surface, its insulation performance will be affected and reduced, which may lead to flashover, causing equipment damage, power system short circuit and other serious accidents. Therefore, accurate and efficient analysis of insulator contamination is crucial to prevent power system accidents and ensure the safe operation of the power system.

[0003] Accurately measuring the pollution level of the insulator surface is of great significance to prevent pollution flashover of insulators. The pollution level of the insulator surface is measured by equivalent salt and ash density parameters, which can only be obtained after sampling, dissolving, filtering and data calculation of the insulator pollution. Among the above steps, the sampling of insulator pollution is particularly difficult, which requires the operator to remove the insulator from the equipment, and it is difficult to ensure that the sampling of the insulator pollution is complete.

[0004] Therefore, it is necessary to propose an insulator pollution collection method based on a fast collection device. Summary of the invention

[0038] Step 0 Preparation: Identify the insulators and power outage-related equipment to be sampled.

[0039] Step 1: Device installation: Install the rapid pollution collection device on the insulator to be collected, and fix the water storage tank 1 and the collection tank 2.

[0049] like Figure 4 As shown, the rapid collection device includes a water tank 1, a collection tank 2, and a pollution collection area division component. The water tank 1 and the collection tank 2 can be respectively installed on the upper and lower sides of the inverted insulator through a fixing buckle 3 and a bracket; distilled water is stored in the water tank 1, and a nozzle is provided at the lower part of the tank body of the water tank 1; the collection tank 2 is located on the lower side of the inverted insulator and close to the edge of the upper surface of the insulator. The collection tank 2 is a tank body with an opening at the top, which is used to collect the scrubbing wastewater. The pollution collection area division component is installed on the base 6 of the insulator through a fixing buckle 3. The pollution collection area division component is a group of chain structure units 7 rotatably installed on the insulator base 6 through a fixing buckle 3. An angle scale is provided between a group of chain structure units 7, and a length scale is formed on the chain structure unit 7.

[0050] The chain structure unit 7 is a flexible body with excellent adaptability. It can make its bottom conform to the undulating structure of the lower surface of the insulator through its own flexible deformation without damaging the surface of the insulator. The chain structure unit 7 can be twisted and deformed within a certain range, while keeping one dimension unchanged in three-dimensional space and allowing free rotation in the other two dimensions.

[0051] Based on the above rapid collection device, the surface contamination of the insulator is collected, such as Figure 3 As shown in the figure, the specific method for collecting contamination on the lower surface of the insulator is as follows:

[0052] Step 0 Preparation: Identify the insulator to be sampled, remove the insulator to be sampled after powering off the relevant equipment, and turn it upside down.

[0053] Step 1: Device installation: Install the rapid pollution collection device on the insulator to be collected, and fix the water storage tank 1 and the collection tank 2.

[0054] Step 2: Select the collection area: select a uniformly polluted area on the upper surface of the insulator, and adjust the pollution collection area division component of the rapid collection device according to the area;

[0055] Specifically, a group of chain structure units 7 of the pollution collection area dividing component are adjusted, one end of the chain structure unit 7 is installed on the insulator base 6 through the fixing buckle 3, and the other end extends outward along the lower surface of the insulator; each chain structure unit 7 is deformed based on the high and low undulating structure of the lower surface of the insulator, and a fan-shaped pollution collection area 8 is formed by a group of chain structure units 7 of the pollution collection area dividing component.

[0056] Step 3: Pollution collection: determine the type of pollution; if the pollution is not lumpy, use a brush to brush the pollution into the collection tank 2; if the pollution is lumpy, use a wooden scraper to cut it into small pieces, and then use a brush to collect it;

[0057] Repeat the above steps to collect as much dirt as possible in the area until only a thin layer of dirt remains.

[0058] Step 4: Final rinse: Use the nozzle provided at the bottom of the water storage tank 1 to rinse the sampling area with distilled water in the water storage tank 1 to ensure that the last remaining dirt can be flushed into the collection tank 2; check whether the color of the sampling area after flushing is the same as when it was not contaminated.

[0060] Step 6: Finishing: After completing the record, remove the rapid pollution collection device and store it properly.

[0061] Example 3

[0062] Based on Example 1 and Example 2, the specific process of calculating the surface area of ​​the insulator for pollution collection is given in this embodiment as follows:

[0063] The formula for calculating the surface area of ​​the insulator is as follows:

[0064]

[0065] When the pollution is collected on the upper surface of the insulator, S is the collection area on the upper surface of the insulator; n is the angle scale reading between a group of metal strips 5, that is, the angle between a group of metal strips 5; l is the length scale reading from the metal strip 5 to the edge of the insulator surface.

[0066] When the pollution collection is performed on the lower surface of the insulator, S is the collection area of ​​the lower surface of the insulator; n is the angle scale reading between a group of chain structure units 7, that is, the angle between a group of chain structure units 7; l is the length scale reading from the chain structure unit 7 to the edge of the insulator surface. It should be noted that: since the lower surface of the insulator is an undulating structure, it is impossible to accurately obtain its pollution collection area using conventional calculation methods, but by using the deformation ability of the chain structure unit 7, the pollution collection area can be equivalent to a sector area, and the value read by the length scale can be regarded as the radius length value of the sector, so as to accurately calculate the collection area of ​​the insulator surface.

[0067] In summary, the insulator pollution collection method based on the rapid collection device can collect pollution on the upper and lower surfaces of the insulator, realizing efficient and reliable collection of insulator pollution. The insulator pollution collection method based on the rapid collection device has the advantages of simple operation and accurate data, and can provide a scientific basis for the pollution status assessment of power system equipment, and help the long-term stable operation of the power system.

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.
