It is mainly used for fast and dynamic regulation of reactive power in power systems.

[0003] However, the photovoltaic grid-connected high-voltage flexible static reactive power generator generates a lot of heat during long-term use, which is not conducive to ensuring the reliability of the device. Therefore, special heat dissipation materials must be coated on the surface of its shell to improve the heat dissipation efficiency and ensure its working reliability.

[0004] However, the existing coating technology mainly relies on manual operation, which is to apply the heat dissipation material to the surface of the substrate and then use tools to scrape it flat.

Each group of moving seats 232 is symmetrically arranged on the bidirectional screws 233. In actual operation, the staff sets the shell upside down on two groups of movable seats 232, and adjusts the distance between each group of movable seats 232 by turning the hand wheel 234, so that the movable seats 232 fit and clamp the shell, and at the same time are convenient for clamping shells of different sizes, thereby improving the applicability of the clamping assembly 23; then the driving unit 25 is started to drive the sliding platform 22 to move from the outside of the board room 1 to the inside; when it is necessary to adjust the coating angle or direction of the shell, the rotating table 231 starts to rotate, driving the clamped shell to rotate, and adjusting the coating angle and direction.

[0028] See also Figure 3 The detection component 5 includes a scanner 1 51 and two sets of scanner 2 52. A support 2 53 is hinged on the lower door 122.

The scanner 1 51 and the scanner 2 52 are both used to scan the surface quality of the shell after coating.

[0029] It should be noted that the support 2 53 is connected to the lower door 122 in a hinged manner, and the gravity of the support 2 53 and the scanner 1 51 can be used to keep the scanner 1 51 in a vertical state to scan the upper surface of the shell.

[0030] The coating system is connected to the console 4 by signal. The coating system includes an acquisition module, an analysis module, a control module and an alarm module. The acquisition module is electrically connected to scanner 1 51 and scanner 2 52. The acquisition module is used to acquire the image of the shell surface after coating and feed it back to the analysis module. The analysis module is used to compare and analyze the coating thickness and coating surface quality after coating. The control module is electrically connected to the conveying mechanism 2 and the coating mechanism 3. The control module is used to control the conveying and coating of the shell. The alarm module is used to give an alarm prompt when the analysis module obtains an abnormal result.

[0031] Coating method of coating equipment for photovoltaic grid-connected high-voltage flexible static reactive power generating device: Step 1: Clamp the shell onto the conveying mechanism 2 , operate the control console 4 to convey the shell into the board room 1 , and have the detection component 5 detect and identify the size of the shell, and then the coating mechanism 3 coats the shell.

[0032] Specifically, the acquisition module acquires the top image of the shell scanned by scanner 1 51 and the side image of the shell scanned by scanner 2 52, identifies the initial length, width and height of the shell, records the initial length as x, the width as y, and the height as z, and then feeds back to the analysis module and the control module. The control module adjusts the lifting height of the coating assembly 32 and the distance between the two groups of spray boxes 321, and then starts the extension and retraction by controlling cylinder 2 33 to adjust the height corresponding to the coating position, and then rotates the rotating table 231 to adjust the corresponding coating direction of the shell.

[0033] It should be noted that the acquisition module records the direction parallel to the top of the shell and scanner 51 as the length direction, the direction perpendicular to the top of the shell and scanner 51 as the width direction, and the direction parallel to the side of the shell and scanner 2 52 as the height direction; the initial shell is a standard cube.

[0034] Step 2: After the coating is completed, the control console 4 controls the conveying mechanism 2 to convey the shell to the outside of the board room 1, and the detection component 5 detects the coating quality of the shell.

[0035] Specifically, the acquisition module acquires the top image of the coated shell body scanned by the scanner 1 51 and the side image of the coated shell body scanned by the scanner 2 52, identifies the maximum length, minimum length, maximum width, minimum width, maximum height and minimum height of the coated shell body, and records the maximum length as x max , the minimum length is recorded as x min , maximum width y max , minimum width y min , maximum height z max and the minimum height z min .

[0036] The analysis module is set with coating standard thickness, theoretical thickness deviation coefficient and actual thickness deviation coefficient set according to coating requirements. The standard thickness is recorded as h, the theoretical thickness deviation coefficient is recorded as N, and the actual thickness deviation coefficient is recorded as n. 长 、n 宽 and n 高 The theoretical deviation coefficient is the basis for judging the uniformity of the coating thickness on the shell surface after coating. The actual deviation coefficient n 长 、n 宽 and n 高 They are the ratios of the coating thickness corresponding to the length, width and height after coating to the standard thickness.

[0037] Taking the length direction as an example, the four sides of the shell are coated, so the difference measured and calculated includes the thickness of the left and right sides of the shell. , the theoretical length after coating is x+2h.

[0038] In x max When ≤x+2h, the analysis module performs additional analysis and judgment to ensure that the coating thickness meets the production standards; In x max >x+2h, the thickness of the applied coating does not meet the production standard, and the analysis module does not perform additional analysis and judgment.

[0039] Additional judgment: In n 长 ≤N, the coating thickness of the shell meets the production standard.长 =0 is the best ideal state.

[0040] In n 长 >N, the coating thickness of the shell does not meet the production standard, and there are coating omissions, protrusions or ripples on the shell surface. At the same time, the analysis module retrieves the image of the shell surface after coating collected by the acquisition module, and identifies whether there are coating omissions or protrusions. If there are local coating omissions, protrusions or ripples, it is caused by the abnormality of the corresponding nozzle 1 326 or nozzle 2 327; if there is a large range of coating omissions, it is caused by an abnormality in the shell surface. If there are large-scale protrusions, it is caused by an abnormal coating material. If there are large-scale ripples, it is caused by the large air output of nozzle 2 327 in the diffuser box 322. The analysis module issues an alarm for the abnormal situation.

[0041] It should be noted that in the width direction, the four sides of the shell are also coated. The difference measured and calculated after coating includes the thickness of the front and rear sides of the shell. , the theoretical width is y+2h, and in the height direction, only the top of the shell is coated, so , the theoretical height is z+h, and the judgment method in the width and height directions is consistent with that in the length direction; when a large-scale anomaly is identified, multiple abnormal situations can exist at the same time.

[0042] Step 3: After coating and testing, the staff will classify and place the shells whose coating thickness meets the standard and those that do not meet the standard.

[0043] Through the above steps, the coating thickness of the shell can be automatically coated and detected, the coating uniformity and efficiency are improved, and manual operations are reduced.
