Description

Technical Field

[0001] This invention relates to the field of insulator defect detection device technology, and in particular to an insulator multi-parameter linkage detection device and method. Background Technology

[0002] Currently, gas-insulated switchgear (GIS) is widely used in substations due to its advantages such as small footprint, high reliability, short installation cycle, and long maintenance cycle. The quality of the GIS pot-type insulator has a decisive impact on the overall quality of the GIS. As the most important insulating component in GIS, the pot-type insulator plays a role in electrical insulation, gas sealing, shell reinforcement, and support. In actual production and live operation, improper product manufacturing process control and uneven tensile stress distribution of bolts at the flange can cause deformation and cracking of the pot-type insulator, leading to GIS leakage, partial discharge, and even insulator surface flashover, resulting in large-scale power outages. Therefore, defect detection of pot-type insulators is of great significance for the safe operation of GIS. Since multiple defects may exist within an insulator simultaneously, multiple manual inspections of individual insulators are required. At present, there is no device that can simultaneously perform linked detection of the galvanized layer and load performance of the insulator, so insulator inspection still needs to be done manually, resulting in high labor costs. Summary of the Invention

[0003] In view of this, the purpose of this invention is to solve the problem that the thickness of the galvanized layer and the load performance of the same insulator need to be manually tested in multiple stages. It provides a multi-parameter linkage testing device for insulators, which can simultaneously and automatically test the creepage distance, galvanized layer thickness, mechanical damage load strength and other items of the insulator. It has the advantages of high testing efficiency, low testing cost and safety and reliability.

[0004] To address the aforementioned technical problems, this invention provides a multi-parameter linkage detection device for insulators, comprising a cabinet equipped with a control module and a defect detection component and a performance detection component staggered along the height of the cabinet within the cabinet. The defect detection component and the performance detection component are connected by a transfer component. The transfer component drives and guides a turnover box pivotally equipped with insulators to pass sequentially through the defect detection component and the performance detection component to detect the galvanized layer thickness and mechanical load performance of the insulators. The defect detection component includes a rotating base supporting the turnover box, a three-dimensional scanning module and a galvanized layer detection sensor arranged on the periphery of the rotating base.

[0005] The output of the control module is communicatively connected to the inputs of the defect detection component and the performance detection component, respectively.

[0006] In a preferred embodiment: the transfer assembly includes a silo and a push rod that cooperates with it. The top of the silo is provided with an inlet and the bottom side is provided with an outlet. After the turnover box is conveyed from top to bottom along the inner cavity of the silo to the outlet of the silo, the push rod extends in opposite directions and pushes the turnover box to move it a predetermined distance away from the silo.

[0007] In a preferred embodiment: the silo includes a first silo and a second silo, wherein the outlet of the first silo and the inlet of the second silo are disposed adjacent to the defect detection component.

[0008] In a preferred embodiment: a slide rail is fixed on the outer side wall of the second silo, and a slider is slidably disposed on the slide rail. The slider moves up and down under the drive of the driving device, and drives the tooling clamp connected to its bottom to stretch or compress the insulator.

[0009] A force sensor is linked to the tooling clamp.

[0010] In a preferred embodiment, the driving device is a cylinder or an electric motor.

[0011] In a preferred embodiment: During the detection state, the rotating base drives the insulator inside the turnover box to rotate circumferentially around its own axis, thereby driving the three-dimensional scanning module and the zinc plating layer detection sensor to detect and transmit data signals back to the control module.

[0012] In a preferred embodiment: the turnover box includes an upper top plate and a lower bottom plate, and a column supported between the two, the column being telescopic along its own height direction.

[0013] In a preferred embodiment: the column is provided with a damper, which provides a buffering force against the sliding direction of the box when the turnover box slides downward.

[0014] In a preferred embodiment: the bottom of the upper top plate and the top of the lower bottom plate are respectively provided with bearing seats for pivot insulators.

[0015] In yet another preferred embodiment, a multi-parameter linkage detection method for insulators as described in the previous embodiment is involved: the detection method includes the following steps:

[0016] Step 1: Encapsulate the insulator in a turnover box and place it in the transfer assembly, then move it to the rotating base of the defect detection assembly;

[0017] Step 2: Drive the rotating base through the control module to rotate the insulator, and simultaneously drive the three-dimensional scanning module and the zinc plating layer detection sensor to scan the external contour of the insulator, calculate and transmit the insulator's external dimensions, creepage distance and zinc plating layer thickness data.

[0018] Step 3: The turnover box continues to be pushed along the circulation assembly to the performance testing assembly. The testing assembly applies tension or pressure to the insulator and transmits back the mechanical failure load data of the insulator.

[0019] Step 4: The insulator that has completed the load performance test is sent out of the testing device, and the next insulator is sealed in a turnover box and placed in the circulation assembly. Steps 1 to 3 are repeated for testing.

[0020] Compared with the prior art, the technical solution of the present invention has the following beneficial effects:

[0021] This invention provides a multi-parameter linkage testing device for insulators. A defect detection component and a performance detection component are linked and installed in a cabinet via a transfer assembly. The insulators are then passed sequentially through a transfer box with the insulators mounted on it by the defect detection component and the performance detection component to test the galvanized layer thickness and load-bearing capacity of the insulators. This device enables automated testing of parameters such as creepage distance, galvanized layer thickness, and mechanical breaking load strength of the insulators. It offers advantages such as high testing efficiency, low testing cost, and high safety and reliability. After the testing process is completed, the device automatically outputs the test results for quality assessment. Compared to the traditional method of manually recording and then assessing the results, this significantly saves time and improves testing efficiency. Attached Figure Description

Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0030] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed", "equipped", "sleeved / connected", "connected", etc., should be interpreted broadly. For example, "connection" can be a wall-mounted connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0031] This embodiment provides a multi-parameter linkage detection device for insulators, such as... Figure 1-6 As shown, the detection device includes a cabinet with a control module and a defect detection component 2 and a performance detection component 3 staggered along the height of the cabinet. The defect detection component 2 and the performance detection component 3 are connected by a transfer component 4. The transfer component 4 drives and guides a turnover box 1 with an insulator pivotally mounted to pass through the defect detection component 2 and the performance detection component 3 in sequence to detect the galvanized layer thickness and mechanical load performance of the insulator. This realizes automated detection of the creepage distance, galvanized layer thickness, and mechanical destructive load strength of the insulator, and has the advantages of high detection efficiency, low detection cost, and safe and reliable application.

[0032] Specifically, the defect detection component 2 and performance detection component 3, which are staggered along the height of the cabinet, are connected by a transfer component 4, which includes a silo and a corresponding push rod. Figure 5As shown, the silo includes a first silo 41 and a second silo 42. The outlet of the first silo 41 and the inlet of the second silo 42 are adjacent to the defect detection component 2. Since the top of the silo is set as the inlet and the bottom side is set as the outlet, the specific internal circulation path of the circulation component 4 includes: the turnover box 1 is conveyed from the inlet of the first silo 41 along its inner cavity from top to bottom to the outlet of the silo. Then, under the push of the first push rod 411, it moves a predetermined distance away from the outlet of the first silo to the rotating base 21 of the defect detection component 2. After the defect detection component 2 has completed the detection, the second push rod 412, which is set at the inlet of the second silo 42, extends to pull the turnover box 1 to the inlet of the second silo 42. After being conveyed from the inlet of the second silo 42 to the outlet of the second silo 42 along its inner cavity, it moves away from the outlet of the second silo under the pushing of the third push rod 421 and onto the tooling clamp 34 of the performance testing component 3. The tooling clamp 34 stretches or compresses the insulator in the turnover box 1 under the control of the control module, and synchronously transmits the load performance data back to the control module through the force sensor. After the load performance test is completed, the tooling clamp 34 releases the insulator, the third push rod 421 extends and pushes the turnover box 1 out of the testing device, and the linkage testing process ends.

[0033] In terms of component coordination, the defect detection assembly 2 includes a rotating base 21 supporting the turnover box 1, a three-dimensional scanning module 22 arranged around the rotating base, and a galvanized layer detection sensor 23. Since the input end of the defect detection assembly 2 is communicatively connected to the output end of the control module, in the detection state, the rotating base 21 drives the insulators inside the turnover box 1 to rotate circumferentially around their own axis, and coordinates with the three-dimensional scanning module 22 and the galvanized layer detection sensor 23 to perform parameter detection and transmit data signals back to the control module. Furthermore, considering the diversity of insulator dimensions, this embodiment sets the upper top plate 11, lower bottom plate 12, and the column 13 supporting the turnover box 1 between the upper top plate and lower bottom plate 12 as an adjustable structure, allowing it to expand and contract along its height to accommodate more insulators of different heights and improve the versatility of the device. Furthermore, considering that the insulators inside the turnover box 1 can rotate more flexibly under the drive of the rotating base 21, this embodiment has bearing seats 14 for pivotally connecting the insulators at the bottom of the upper top plate 11 and the top of the lower bottom plate. In addition, this embodiment also has a damper on the column 13. When the turnover box 1 slides downward, the damper can provide a buffering force to the turnover box 1 in the opposite direction of the box's sliding direction, so as to avoid damage to the insulators during the process of the turnover box 1 falling from top to bottom along the inner cavity of the silo to the outlet.

[0034] It should be noted that during the zinc plating thickness detection process, the zinc plating detection sensor 23 needs to be in contact with the outer surface of the insulator during detection. Furthermore, to ensure comprehensive detection of the zinc plating on the outer surface of the insulator, the zinc plating detection sensor 23 needs to move along the height direction of the insulator during rotation. Therefore, in this embodiment, a position adjustment mechanism 231 is also provided on the zinc plating detection sensor 23 to adjust the two degrees of freedom of movement of the zinc plating detection sensor 23 in the height and horizontal directions. Figure 3 As shown.

[0035] The performance testing component 3 is located at the outlet of the second silo 42. Its structure includes a slide rail 31 fixed to the outer wall of the second silo 42, on which a slider 32 slides. The slider 32 moves up and down under the drive of a driving device 33 (a cylinder or motor), which drives a tooling clamp 34 connected to the bottom of the slider 32 to stretch or compress the insulator. Furthermore, since the input of the performance testing component 3 is communicatively connected to the output of the control module, and a force sensor is linked to the tooling clamp, with its output connected to the input of the control module, the force sensor can synchronously and in real-time measure and transmit the mechanical failure load data of the insulator to the control module when the tooling clamp 34 stretches or compresses the insulator, thus achieving automated detection of the insulator's load performance.

[0036] The detection method based on the insulator multi-parameter linkage detection device described in this embodiment includes the following steps:

[0037] Step 1: Encapsulate the insulator in the turnover box 1 and place it in the transfer assembly 4, and move it to the rotating base 21 of the defect detection assembly 2;

[0038] Step 2: Drive the rotating base through the control module to rotate the insulator, and simultaneously drive the three-dimensional scanning module 22 and the zinc coating detection sensor 23 to scan the external contour of the insulator, calculate and transmit the insulator's external dimensions, creepage distance and zinc coating thickness data.

[0039] Step 3: The turnover box 1 continues to be pushed along the circulation component 4 to the performance testing component 3. The testing component 3 applies tension or pressure to the insulator and transmits back the mechanical failure load data of the insulator.

[0040] Step 4: The insulator that has completed the load performance test is sent out of the testing device, and the next insulator is sealed in the turnover box 1 and placed in the circulation component 4. Steps 1 to 3 are repeated for testing.

[0041] The above description is merely a preferred embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any non-substantial modifications made to the present invention by those skilled in the art within the scope of the technology disclosed in the present invention using this concept shall be deemed as an infringement of the protection scope of the present invention.
