Description

Technical Field

[0001] This utility model relates to the technical field of electrical performance testing equipment, and in particular to a rapid electrical performance testing device for an inner conical sleeve. Background Technology

[0002] As a critical component in power systems, the electrical performance of the inner tapered bushing directly affects the safe and stable operation of power equipment. Therefore, it must undergo rigorous electrical performance testing for quality assessment before leaving the factory. In current electrical performance testing of inner tapered bushings, the upper surface of the product is connected to high voltage, and the insert surface is grounded. The grounding surface must be sealed with a rubber plug to ensure the test's sealing and accuracy. Currently, the plug is installed using the downward pressure of the bolts during installation, which requires alternating bolt tightening to ensure a smooth fit. Insufficient tightening can easily create air gaps, affecting the product's qualification. After voltage is applied, the bolts are loosened to remove the plug, which requires considerable force to vacuum-adhere. Another person is needed to stabilize the product during plug installation to prevent it from shaking when force is applied.

[0003] The existing product weighs 22kg each, and workers have to find the right angle to move it when installing the plug, which is difficult. At the same time, the installation of the plug relies on the compression of the bolt, which is cumbersome and time-consuming. Furthermore, the vacuum adsorption inside the plug makes it difficult to remove, and it requires two employees to work together to remove it. In order to address this technical problem, this application proposes a rapid electrical performance testing device for an inner conical sleeve. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid electrical performance testing device for inner conical sleeves. This testing device uses a cylinder to drive the disassembly and assembly of the plug, replacing the traditional bolt tightening, eliminating the tedious steps of alternating bolt tightening, and requiring no additional wiring operations, thereby improving work efficiency. At the same time, there is no need for manual handling of the product to adjust the angle, and a single person can complete the product placement.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A rapid electrical performance testing device for an inner conical sleeve includes a main support. A secondary support is bolted to the top of the main support, and a crossbeam is bolted to the top of the secondary support. The inner wall of the crossbeam is connected to a universal ball joint via a pneumatic assembly. A mounting bracket is mounted on the bottom side of the universal ball joint, and a plug is mounted on the inner wall of the mounting bracket. Two fixing plates are mounted on the inner side of the main support, and an insulating support is fixedly connected to the top side of the two fixing plates. A high-voltage connection terminal is fixedly connected to the top side of one of the insulating supports. Multiple limiting blocks are slidably connected to the top side of the main support, and a grounding mounting plate is provided on the outer wall of the limiting blocks.

[0006] Furthermore, the pneumatic assembly includes a cylinder mounted on the inner wall of the crossbeam via a fixed bracket, a connecting block is provided at the driving end of the cylinder, guide columns are provided on both sides of the cylinder, and the bottom side of the connecting block is connected to a universal ball joint.

[0007] Furthermore, the outer wall of the guide column is slidably connected to the crossbeam, and the bottom side of the guide column is connected to the connecting block.

[0008] Furthermore, a filter is installed on the front left side of the main support, an air intake regulating valve is installed on the outer wall of the left end of the main support, and an air control valve is installed on the right side of the main support.

[0009] Furthermore, the filter output is connected to the intake regulating valve, the intake regulating valve output is connected to the pneumatic control valve, and the pneumatic control valve is connected to the cylinder via a connecting pipe.

[0010] Furthermore, a test hole is provided on the top of the grounding mounting plate, and the bottom outer wall of the plug is connected to the test hole.

[0011] Furthermore, casters are installed around the bottom of the main support.

[0012] This utility model has the following beneficial effects: In this invention, the experimental device uses a cylinder to drive the disassembly and assembly of the plug, eliminating the tedious steps of alternating bolt tightening. Furthermore, product grounding and high-voltage wiring are achieved simply by placing the plug in, without the need for additional wiring operations. At the same time, the clamping force provided by the cylinder is stable and much greater than that of bolt compression. Combined with the angle adjustment of the universal ball joint and the sealing effect of the sealing ring, it can effectively avoid air gaps caused by improper plug installation, reduce product misjudgment due to human error, and improve the accuracy of product qualification determination.

[0013] In this invention, the experimental device does not require manual adjustment of the angle when installing the product. The cylinder automatically pushes the plug to fit, and a single person can complete the entire process, including product placement and pneumatic valve operation, avoiding the need for multiple people to work together, reducing labor costs and labor intensity. Furthermore, by replacing different specifications of grounding mounting plates and plug components, it can be adapted to various models of inner cone sleeve products, making it highly versatile.

[0017] Reference Figures 1-3 This utility model provides an embodiment of a rapid electrical performance testing device for an inner conical sleeve, comprising a main support 1, a secondary support 2 bolted to the top of the main support 1, a crossbeam 3 bolted to the top of the secondary support 2, the inner wall of the crossbeam 3 connected to a universal ball joint 12 via a pneumatic assembly, a mounting bracket 14 mounted on the bottom side of the universal ball joint 12, a plug 13 mounted on the inner wall of the mounting bracket 14, two fixing plates 4 mounted on the inner side of the main support 1, an insulating support 6 fixedly connected to the top side of the two fixing plates 4, a high-voltage connection terminal 7 fixedly connected to the top side of one of the insulating supports 6, and multiple limiting blocks 19 slidably connected to the top side of the main support 1, with a grounding mounting plate 8 provided on the outer wall of the limiting block 19.

[0018] Specifically, the product is directly installed and fixed on the bottom side of the grounding mounting plate 8. Then, the grounding mounting plate 8 is aligned with the limiting block 19 and placed in it. The limiting block 19 and the main bracket 1 will fix the grounding mounting plate 8. The bottom of the product will be connected to the high-voltage connection terminal 7 at the top of the insulating support 6. Adjust the angle of the plug 13 fixed on the bottom side of the universal ball head 12 through the mounting bracket 14. Then, the plug 13 is driven by the pneumatic component to block the grounding mounting plate 8. Then, the voltage is increased to start the test. After the test is completed, the pneumatic component drives the plug 13 to reset. Then, the grounding mounting plate 8 can be removed and the product can be disassembled.

[0019] Reference Figures 2-4The pneumatic assembly includes a cylinder 9 mounted on the inner wall of the crossbeam 3 via a fixed bracket. A connecting block 11 is provided at the drive end of the cylinder 9, and guide columns 10 are provided on both sides of the cylinder 9. The bottom side of the connecting block 11 is connected to the universal ball joint 12. The outer wall of the guide column 10 is slidably connected to the crossbeam 3, and the bottom side of the guide column 10 is connected to the connecting block 11. The connecting block 11 is driven to move downward by the cylinder 9. The guide columns 10 on both sides of the connecting block 11 prevent the connecting block 11 from shifting during the push of the cylinder 9. Subsequently, the connecting block 11 will drive the universal ball joint 12 to move downward.

[0020] A filter 15 is installed on the front left side of the main support 1. An intake regulating valve 16 is installed on the outer wall of the left end of the main support 1. A pneumatic control valve 17 is installed on the right side of the main support 1. The output end of the filter 15 is connected to the intake regulating valve 16, and the output end of the intake regulating valve 16 is connected to the pneumatic control valve 17. The pneumatic control valve 17 is connected to the cylinder 9 through a connecting pipe. External gas enters the intake regulating valve 16 through the filter 15 and then enters the pneumatic control valve 17 through the intake regulating valve 16. The operation of the cylinder 9 can be controlled by adjusting the pneumatic control valve 17.

[0021] The grounding mounting plate 8 has a test hole 18 on its top. The bottom outer wall of the plug 13 is connected to the test hole 18. The test hole 18 is used to seal the air inside the plug 13. The main support 1 has casters 5 installed around its bottom side to facilitate the transportation of the device.

[0022] Working principle: Specifically, the product is directly installed and fixed on the bottom side of the grounding mounting plate 8. Then, the grounding mounting plate 8 is aligned with the limiting block 19 and placed in.

The bottom of the product will be connected to the high-voltage connection terminal 7 at the top of the insulating support 6. The high-voltage connection terminal 7 is equipped with a protective sleeve to isolate the current. The angle of the plug 13 is controlled by adjusting the universal ball joint 12. By activating the air intake regulating valve 16, the gas enters the air control valve 17 after being filtered by the filter 15. The pneumatic control valve 17 activates the cylinder 9, which drives the connecting block 11 to move downwards. The guide posts 10 on both sides of the connecting block 11 prevent the connecting block 11 from shifting during the push of the cylinder 9. Subsequently, the connecting block 11 drives the universal ball head 12 to move downwards, and drives the plug 13 on the mounting bracket 14 to block the test hole 18 of the grounding mounting plate 8. The plug 13 has an elastic sealing ring, which can prevent air gaps from forming in the product during testing. Then, the voltage is increased to start the test. After the test is completed, the pneumatic control valve 17 is activated to activate the cylinder 9 to reset the plug 13. Then, the grounding mounting plate 8 can be removed and the product can be disassembled.
