Description

Technical Field

[0001] This application relates to the field of wind farm insulation performance testing technology, and in particular to a device for testing the insulation performance of wind farm collector lines. Background Technology

[0002] In wind farms, collector lines play a crucial role in transmitting electrical energy generated by wind turbines to substations or the power grid. The quality of their insulation directly impacts the system's safety, stability, and operational efficiency. Therefore, to ensure the stable and safe operation of wind farms, it is necessary to test the insulation performance of the wind farm's collector lines.

[0003] Currently, the insulation performance of collector lines in wind farms is mainly tested using a support rod, a handle mounted on the support rod, a detection head mounted at one end of the support rod, and a current detector installed inside the support rod. In practice, the support rod is held manually, and the detection head is brought into contact with the outer wall of the collector lines in the wind farm. The insulation performance of the collector lines is then tested by observing the reading on the current detector.

[0004] While existing wind farm collector line insulation performance testing devices can test the insulation performance of wind farm collector lines manually, the fixed angle of the testing head makes it difficult to smoothly test the collector lines in the confined spaces of the wind farm. This results in poor flexibility and low testing efficiency. Furthermore, since maintenance personnel must hold the device continuously throughout the testing process, the manual labor intensity is high during prolonged testing. Summary of the Invention

[0023] The present application will be further described in detail below with reference to the accompanying drawings.

[0024] To better understand the technical solutions presented in the embodiments of this application, the structure and working principle of existing wind farm collector line insulation performance testing devices will first be introduced.

[0025] The existing wind farm collector line insulation performance testing device mainly consists of a support rod, a handle installed on the support rod, a test head installed at one end of the support rod, and a current detector installed inside the support rod. In actual testing, the support rod is held manually and the test head is brought into contact with the outer wall of the collector line in the wind farm. The insulation performance of the wind farm collector line is tested by observing the reading on the current detector.

[0026] Please see Figures 1-4This application discloses a wind farm collector line insulation performance testing device, which includes a sleeve rod 3. A telescopic rod 2 is installed at one end of the sleeve rod 3. A universal adjustment mechanism 7 is installed at the end of the telescopic rod 2 opposite to the sleeve rod 3. The universal adjustment mechanism 7 includes a second motor 71, a U-shaped plate 72, a first rotating block 73, a second rotating block 74, a third motor 75, and a rotating groove 76. An insulation testing mechanism 1 is installed between the first rotating block 73 and the sleeve rod 3. The insulation testing mechanism 1 includes a testing head 11, a connecting wire 12, and a current detector 13. An auxiliary support assembly 8 is also installed on the outside of the sleeve rod 3. The auxiliary support assembly 8 includes a support plate 81, a friction pad 82, a rotating shaft 83, and a support plate 84. Two handles 4 are also installed at the top of the sleeve rod 3 by bolts.

[0027] Specifically, when testing the insulation performance of wind farm collector lines for a short period of time, the sleeve rod 3 is lifted directly by the handle 4, and the detection head 11 is brought into contact with the corresponding detection part on the wind farm collector line. The insulation performance of the wind farm collector line is then tested and judged by observing the reading on the current detector 13. When testing in a confined space within the wind farm, the detection head 11 can be rotated and adjusted in the vertical plane with the cooperation of motor 3 75 and rotating block 2 74, and in the horizontal plane with the cooperation of motor 2 71 and rotating block 1 73. This ensures that the detection head 11 can be used for testing at multiple angles, facilitating smooth testing in confined spaces on the wind farm collector line. When the device needs to test the insulation performance of the collector lines for a long period of time, the support plate 81 can be rotated out so that the support plate 84 contacts the support base of the detection part. This allows the auxiliary support component 8 to provide auxiliary support for the sleeve rod 3, reducing the manual labor intensity during long-term testing.

[0028] Please see Figure 2 A telescopic mechanism 5 is also installed between the telescopic rod 2 and the sleeve rod 3. The telescopic mechanism 5 includes a motor 53, a screw 52 and a screw groove 51.

[0029] In one implementation, motor 53 is mainly used to rotate screw 52. After screw 52 rotates, it will cause the inner cup of telescopic rod 2 to slide out under the action of thread transmission, so as to realize the adjustment of the overall length of the device.

[0030] Please see Figure 2 The screw 52 is rotatably mounted in the middle of the sleeve rod 3. The screw groove 51 is opened on the telescopic rod 2 and mates with the screw 52. The motor 53 is installed inside the sleeve rod 3 at the power input end directly opposite the screw 52.

[0031] As one implementation method, the rotating installation method allows the screw 52 to rotate easily relative to the sleeve 3, and the motor 53 is mainly used to provide power for the rotation of the screw 52.

[0032] Please see Figure 2 A battery 6 is installed inside the sleeve rod 3 on one side of the motor 53. The sleeve rod 3 has a hollow structure at the location of the motor 53 and the battery 6.

[0033] As one implementation, the sleeve rod 3 is also equipped with heat dissipation holes on the part facing the motor 53 and the battery 6 to ensure normal heat dissipation of the motor 53 during use. The battery 6 is electrically connected to the motor 53, the second motor 71, and the third motor 75.

[0034] Please see Figures 1-4 The rotating groove 76 is opened at one end of the telescopic rod 2 opposite to the sleeve rod 3. The rotating block 2 74 is rotatably installed in the rotating groove 76. The motor 3 75 is installed on the outer wall of the telescopic rod 2 directly opposite the power input end of the rotating block 2 74.

[0035] In one implementation, the rotation of the detection head 11 in the vertical plane can be adjusted by the motor 3 75 driving the rotating block 2 74.

[0036] Please see Figures 1-4 The U-shaped plate 72 is connected to the end of the rotating block 74 facing away from the rotating groove 76. The motor 71 is installed at the top center of the U-shaped plate 72. The rotating block 74 is connected to the power output end of the motor 71. The rotating block and the U-shaped plate 72 rotate in cooperation.

[0037] As one implementation method, the rotation of the detection head 11 in the horizontal plane can be adjusted by the motor 2 71 driving the rotating block 1 73 to rotate.

[0038] Please see Figure 1 , Figure 3 and Figure 4 The detection head 11 is fixedly connected to the rotating block 73, the current detector 13 is installed on the sleeve rod 3 located on one side of the handle 4, and the connecting wire 12 is connected between the detection head 11 and the current detector 13.

[0039] As one implementation, the current detector 13 is based on the same principle as the current detection device in patent number CN217305450U.

[0040] Please see Figure 1 and Figure 4 The support plate 81 has a U-shaped structure. The support plate 81 is rotatably fitted with the two side walls of the sleeve rod 3, and the friction pad 82 is bonded to the inner two side walls of the support plate 81.

[0041] As one implementation method, the support plate 81 is mainly used to conveniently connect the support plate and the sleeve rod 3, and the friction pad 82 is mainly used to reliably limit the support plate 81 on the sleeve rod 3 after rotation and retraction.

[0042] Please see Figure 1 and Figure 4The rotating shaft 83 is rotatably mounted on one end of the support plate 81, and a support plate 84 is inserted into the end of the rotating shaft 83 facing away from the support plate 81.

[0043] As one implementation method, the rotating shaft 83 can ensure that the support plate 81 can rotate easily relative to the support plate 84, so that the position of the sleeve rod 3 can be easily adjusted according to the actual testing needs during the actual measurement process, so as to ensure that the detection head 11 can smoothly contact the detection part on the wind farm collector line.

[0044] The specific working principle is as follows: When testing the insulation performance of the wind farm's collector lines in a short time, the handle 4 is used to lift the sleeve 3, and the detection head 11 is brought into contact with the corresponding testing part on the wind farm's collector lines. The insulation performance of the wind farm's collector lines is then tested and judged by observing the reading on the current detector 13. When testing in the confined space of the wind farm, the detection head 11 is adjusted vertically by the cooperation of motor 3 75 and rotating block 2 74, and horizontally by the cooperation of motor 2 71 and rotating block 1 73. This ensures that the detection head 11 can be used for testing at multiple angles, facilitating smooth testing in the confined space of the wind farm's collector lines. When the device needs to test the insulation performance of the electric field collector line for a long time, the support plate 81 can be rotated out so that the support plate 84 contacts the support base of the test part. This allows the auxiliary support component 8 to provide auxiliary support for the sleeve rod 3, reducing the labor intensity of manual labor during long-term testing. Under the action of this insulation performance testing device, the angle of the test head 11 can be automatically adjusted according to the size of the test part in the wind farm collector line, making the insulation performance testing process on the wind farm collector line smoother and more efficient. It can also use the auxiliary support component 8 to provide auxiliary support for the insulation testing mechanism 1 during long-term testing, thereby effectively reducing the labor intensity of manual labor during the testing process.

[0045] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
