Description

Technical Field

[0001] This invention relates to the technical field of insulator aging test equipment, specifically an ultra-high voltage insulator aging test equipment. Background Technology

[0002] Insulators are critical components in power systems, used to support conductors and isolate potentials; their performance directly affects the safe and stable operation of the power grid. With the development of ultra-high voltage (UHV) transmission technology, the aging problem of insulators under complex environments (such as high humidity, high salt spray, and temperature variations) has become increasingly prominent. Therefore, conducting aging tests on insulators to evaluate their weather resistance and durability is of great significance. Currently, insulator aging tests typically include various testing methods such as electrical aging, thermal aging, mechanical aging, and environmental aging. Common test setups mainly include environmental simulation chambers, high-voltage power supplies, temperature and humidity control systems, salt spray devices, and mechanical impact mechanisms. However, existing technologies have the following main problems: 1. Traditional experimental setups require manual placement of insulators into the environmental chamber and manual connection of high-voltage and grounding electrodes. Because the experiment involves high voltage (such as ±1000kV DC or AC high voltage), operators face the risk of electric shock. Furthermore, during impact testing, if the insulators break due to aging, flying fragments may injure the personnel, making the setup unsafe. 2. The installation, removal, and electrode connection of insulators rely on manual operation, resulting in a long experimental cycle; 3. Existing equipment typically has a complex electrical structure. In particular, electrical components are prone to short circuits or poor contact when operating in high humidity and high salt spray environments for extended periods, leading to an increased failure rate. Summary of the Invention

[0003] In view of the above-mentioned shortcomings in the existing technology, the purpose of this invention is to provide an insulator aging test device that improves test safety, speeds up test efficiency, and reduces device failure rate.

[0004] The technical solution adopted by the present invention to achieve the above objectives is: an ultra-high voltage insulator aging test device, comprising an environmental simulation chamber and an environmental simulation system cooperating with the environmental simulation chamber, wherein a test assembly is provided inside the environmental simulation chamber, and an inlet and outlet are provided on the environmental simulation chamber, with a chamber door provided at the inlet and outlet, the test assembly comprising a feeding and discharging mechanism, a conductive mechanism and an impact mechanism, wherein the feeding and discharging mechanism is provided inside the environmental simulation chamber corresponding to the inlet and outlet, and the feeding and discharging mechanism includes a carrying platform capable of linear motion, the carrying platform being used to carry the insulator to be tested; The environmental simulation chamber is equipped with the conductive mechanism, which includes a lifting module, a high-voltage electrode, and a grounding electrode. A set of the lifting modules is located on both sides of the material support platform in the environmental simulation chamber. Each set of the lifting modules includes a lifting platform. The high-voltage electrode is fixedly connected to one set of the lifting platforms, and the grounding electrode is fixedly connected to the other set of the lifting platforms. Each set of lifting modules is coordinated with the feeding and discharging mechanism through a linkage structure. After the feeding and discharging mechanism drives the insulator to the test position, the high-voltage electrode and the low-voltage electrode come into contact with the fittings at both ends of the insulator. The environmental simulation chamber is also equipped with an impact mechanism corresponding to the material support platform, which is used to impact the insulator.

[0005] In the above technical solution, in order to provide the required power to the feeding and discharging mechanism and the impact mechanism, a drive device is fixedly connected to the outside of the environmental simulation chamber. The drive device is powered to the feeding and discharging mechanism through a first transmission structure, and the drive device is powered to the impact mechanism through a second transmission structure. Furthermore, the first transmission structure includes a first one-way transmission component, and the second transmission structure includes a second one-way transmission component. Under the action of the first one-way transmission component and the second one-way transmission component, when the driving device drives the feeding and discharging mechanism to work, the impact mechanism does not work, and when the driving device drives the impact mechanism to work, the feeding and discharging mechanism does not work.

[0006] In the above technical solution, the feeding and discharging mechanism adopts the following structure: The feeding and discharging mechanism also includes a linear motion table, a reciprocating screw, and a guide rail. The guide rail is fixedly connected to the bottom surface of the environmental simulation silo. The linear motion table is slidably connected to the guide rail. The reciprocating screw is threadedly connected to the linear motion table. The material support platform is fixedly connected to the linear motion table. The driving device and the reciprocating screw are powered through the first transmission structure.

[0007] In the above technical solution, the lifting module adopts the following structure: The lifting module also includes a lifting frame, a one-way lead screw, and a connecting frame. The lifting frame is fixedly connected inside the environmental simulation chamber. The lifting platform is slidably connected to the lifting frame. The one-way lead screw is threadedly connected to the lifting platform. The connecting frame is fixedly connected to the lifting platform. The high-voltage electrode or grounding electrode is fixedly connected to the connecting frame.

[0008] In one embodiment, the linkage structure is selected from the following structures: The linkage structure includes a first worm, a first worm wheel, a transmission rack, and a transmission gear. The bottom end of the one-way lead screw is fixedly connected to a first input shaft, and the first worm wheel is fixedly connected to the first input shaft. The first worm is rotatably connected to the first worm wheel inside the environmental simulation chamber. The first worm wheel meshes with the first worm. The transmission gear is fixedly connected to the first worm. The transmission rack is fixedly connected to the linear motion stage, and the transmission rack meshes with the transmission gear.

[0009] In the above technical solution, the structure of the impact mechanism is as follows: The impact mechanism includes a weight, a pulley, a winding wheel, and a winding release component. The winding wheel is rotatably connected inside the environmental simulation chamber. Multiple sets of pulleys are rotatably connected to the winding wheel inside the environmental simulation chamber. A suspension rope is fixedly connected to the winding wheel. The suspension rope passes through each set of pulleys. The weight is fixedly connected to the end of the suspension rope. The weight is located at the top of the environmental simulation chamber. The environment simulation chamber is equipped with a winding release component in conjunction with the winding wheel. The winding release component can release the traction force of the suspension rope, causing the weight to fall due to gravity. The winding release component and the drive device are connected by the second transmission structure, so that the drive device can drive the winding wheel to wind up the suspension rope through the winding release component.

[0010] In the above technical solution, the winding and releasing component adopts the following structure: The take-up and release component includes a spline sleeve, a spline shaft, a first drive gear, a second drive gear, a second worm, a second worm wheel, a spring, and an electromagnet. The spline sleeve is fixedly connected to the axle of the take-up reel. The first drive gear is provided inside the environmental simulation chamber corresponding to the spline sleeve. The spline shaft is fixedly connected to the first drive gear and engages with the spline sleeve. A motion disk is rotatably connected to the first drive gear. A motion column is fixedly connected to the motion disk. A guide frame is fixedly connected inside the environmental simulation chamber. The motion column is slidably connected to the guide frame. The spring is sleeved on the motion column. One end of the spring is fixedly connected to the motion disk, and the other end is fixedly connected to the guide frame. The electromagnet is fixedly connected to the guide frame and engages with the motion disk. When the electromagnet attracts the motion disk, the spline shaft disengages from the spline sleeve. Inside the environmental simulation chamber, near the first drive gear, a second drive gear is rotatably connected. The second drive gear meshes with the first drive gear. A second worm gear is fixedly connected to the axle of the second drive gear. Inside the environmental simulation chamber, a second worm is rotatably connected. The second worm meshes with the second worm gear. The second worm gear is connected to the drive device through the second transmission structure.

[0011] In the above technical solution, the first transmission structure and the second transmission structure are selected from the following structures: The first transmission structure further includes a second input shaft. The power output end of the drive device is fixedly connected to the second input shaft. The second input shaft is poweredly connected to the reciprocating screw. The second input shaft is provided with the first one-way transmission component, which is a first ratchet component. The second transmission structure also includes a third input shaft, which is poweredly connected to the second worm gear. The third input shaft is provided with a second one-way transmission component, which is a second ratchet component. The second input shaft and the third input shaft are connected by a belt drive, and the belt drive is located on the power input side of the first one-way drive and the second one-way drive.

[0012] In the above technical solution, the following structure is selected to achieve automatic closing of the warehouse door: The door is connected to the environmental simulation chamber via a torsion spring hinge. The transmission rack cooperates with the door, so that when the linear motion table drives the transmission rack to move outward, the transmission rack can push the door open. When the linear motion table drives the transmission rack to move inward, the door closes under the action of the torsion spring hinge.

[0013] In the above technical solution, the environmental simulation system includes a humidity control module, a temperature control module, a salt spray supply module, and a voltage supply module. The temperature control module is used to control the temperature inside the environmental simulation chamber, the humidity control module is used to control the humidity inside the environmental simulation chamber, the salt spray supply module is used to spray salt spray onto the insulator, and the voltage supply module is electrically connected to the high-voltage electrode and the grounding electrode so that voltage can be supplied to the insulator. The salt spray supply module includes a salt spraying component, which is fixedly connected inside the environmental simulation chamber.

[0014] The beneficial effects of this invention are: 1. The insulator to be tested can be placed on the carrying platform, and then the insulator is driven into the environmental simulation chamber by the feeding and discharging mechanism. At the same time, the high-voltage electrode is in contact with one end of the insulator's hardware, and the grounding electrode is in contact with the other end of the insulator's hardware. The environment inside the environmental simulation chamber can be adjusted to the test environment through the environmental simulation system, such as test temperature, humidity, voltage supplied to the insulator, and salt spray spraying onto the insulator. After the insulator has been in the test environment for a period of time, the insulator can be impacted by the impact mechanism. After the test is completed, the insulator can be transported out of the environmental simulation chamber by the feeding and discharging mechanism. The aging resistance of the insulator can be judged by observing the surface condition of the insulator. Through the above structure, the automatic feeding and discharging of the insulator can be realized, avoiding personnel entering the test chamber and improving test safety. At the same time, the high-voltage electrode, grounding electrode and insulator can be automatically connected or disconnected, reducing manual operation, improving safety and speeding up the test efficiency. 2. The drive device can drive the feeding and discharging mechanism to meet the feeding and discharging requirements of insulators. In addition, the drive device can also drive the impact mechanism to perform the required functions. Furthermore, the power of the feeding and discharging mechanism is used to realize the operation of the lifting module, realizing the power connection and disconnection between the high-voltage electrode, the grounding electrode and the insulator fittings. This structure greatly reduces the power source and various electrical components required for the overall device. Moreover, there are no electrical components in the environmental simulation chamber, which reduces the failure rate of the device and makes it more durable. Attached Figure Description

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0018] Please see Figures 1-14 An ultra-high voltage insulator aging test device includes an environmental simulation chamber 100 and an environmental simulation system that works in conjunction with the environmental simulation chamber 100. Please refer to [link to relevant documentation]. Figure 7The environmental simulation system includes a humidity control module, a temperature control module, a salt spray supply module, and a voltage supply module. The temperature control module is used to control the temperature inside the environmental simulation chamber 100, the humidity control module is used to control the humidity inside the environmental simulation chamber 100, the salt spray supply module is used to spray salt spray onto the insulators, and the voltage supply module is electrically connected to the high-voltage electrode 302 and the grounding electrode 303, so that voltage can be supplied to the insulators. Specifically, the salt spray supply module includes a salt spraying component 103 for spraying salt spray, and the salt spraying component 103 is fixedly connected inside the environmental simulation chamber 100. Furthermore, the environmental simulation chamber 100 is equipped with a test assembly, which includes an inlet / outlet mechanism 200, a conductive mechanism 300, and an impact mechanism 500. The environmental simulation chamber 100 has an inlet / outlet 101 with a door 102 at each inlet / outlet 101. The inlet / outlet mechanism 200 is located inside the environmental simulation chamber 100 corresponding to the inlet / outlet 101. The inlet / outlet mechanism 200 is used to allow the insulators to be tested to enter and exit. In this embodiment, please refer to... Figure 9 The feeding and discharging mechanism 200 includes a linear motion table 201, a reciprocating screw 202, and a guide rail 203. Specifically, the guide rail 203 is fixedly connected to the bottom surface of the environmental simulation chamber 100, the linear motion table 201 is slidably connected to the guide rail 203, the reciprocating screw 202 is threadedly connected to the linear motion table 201, and a carrying platform 204 is fixedly connected to the linear motion table 201. The carrying platform 204 is used to carry the insulator to be tested, and the carrying platform 204 is provided with a positioning groove 2041. When the reciprocating screw 202 rotates, the linear motion table 201 can move linearly on the guide rail 203. At the same time, it can drive the insulator to move linearly, so that the insulator can enter the environmental simulation chamber 100 from the outside through the inlet and outlet 101, and can also move out of the environmental simulation chamber 100 to the outside. Furthermore, please refer to Figure 5 , Figure 9 The environmental simulation chamber 100 is equipped with a conductive mechanism 300, which is used to provide voltage to the insulator. The conductive mechanism 300 includes a lifting module 301, a high-voltage electrode 302, and a grounding electrode 303. That is, a set of lifting modules 301 are provided on both sides of the material support platform 204 in the environmental simulation chamber 100. Each set of lifting modules 301 includes a lifting platform 3011. One set of lifting platforms 3011 is fixedly connected to the high-voltage electrode 302, and the other set of lifting platforms 3011 is fixedly connected to the grounding electrode 303. Each set of lifting modules 301 cooperates with the feeding and discharging mechanism 200 through a linkage structure 400, so that after the feeding and discharging mechanism 200 drives the insulator to the test position, the high-voltage electrode 302 and the low-voltage electrode contact the fittings at both ends of the insulator. Here, the high-voltage electrode 302 and the grounding electrode 303 are electrically connected to the voltage supply module respectively. Furthermore, in this embodiment, please refer to Figure 9 The lifting module 301 also includes a lifting frame 3012, a one-way screw 3013, and a connecting frame 3014. That is, the lifting frame 3012 is fixedly connected inside the environmental simulation chamber 100, the lifting platform 3011 is slidably connected to the lifting frame 3012, the one-way screw 3013 is threadedly connected to the lifting platform 3011, the connecting frame 3014 is fixedly connected to the lifting platform 3011, and a high-voltage electrode 302 or a grounding electrode 303 is fixedly connected to the connecting frame 3014. When the one-way screw 3013 rotates, the lifting platform 3011 can drive the grounding electrode 303 or the high-voltage electrode 302 to rise and fall. Furthermore, in this embodiment, please refer to... Figure 10 The linkage structure 400 includes a first worm 401, a first worm wheel 402, a transmission rack 403, and a transmission gear 404. Specifically, a first input shaft 405 is fixedly connected to the bottom end of the one-way lead screw 3013, and a first worm wheel 402 is fixedly connected to the first input shaft 405. Inside the environmental simulation chamber 100, a first worm 401 is rotatably connected to the first worm wheel 402. The first worm wheel 402 meshes with the first worm 401, and a transmission gear 404 is fixedly connected to the first worm 401. A transmission rack 403 is fixedly connected to the aforementioned linear motion table 201. The transmission rack 403 and... The transmission gear 404 is engaged, so when the linear motion table 201 moves inward, the transmission rack 403 causes the transmission gear 404 to rotate, which in turn drives the first worm 401 to rotate the first worm wheel 402, causing the one-way lead screw 3013 to rotate. At this time, the lifting table 3011 drives the high voltage electrode 302 and the grounding electrode 303 to descend until they contact the hardware at both ends of the insulator. When the linear motion table 201 moves outward, the lifting table 3011 drives the high voltage electrode 302 and the grounding electrode 303 to rise under the action of the transmission rack 403 and the transmission gear 404. To put it more precisely, please refer to Figure 3 The aforementioned door 102 is connected to the environmental simulation chamber 100 via a torsion spring hinge. The transmission rack 403 cooperates with the door 102. When the linear motion table 201 drives the transmission rack 403 to move outward, the transmission rack 403 can push the door 102 to open. When the linear motion table 201 drives the transmission rack 403 to move inward, the door 102 closes under the action of the torsion spring hinge. In this way, the power of the linear motion table 201 can be used to realize the automatic opening and closing of the door 102. Compared with manual doors, the operation process is reduced, and compared with automatic door opening and closing, its failure rate is lower. Furthermore, within the environmental simulation chamber 100, corresponding to the material support platform 204, there is also an impact mechanism 500. The impact mechanism 500 is used to impact the insulators. For details, please refer to [link / reference needed]. Figure 9 , Figure 11The impact mechanism 500 includes a weight 501, a pulley 502, a winding wheel 503, and a winding release component 504. Specifically, a winding wheel 503 is rotatably connected inside the environmental simulation chamber 100, and multiple sets of pulleys 502 are rotatably connected to the winding wheel 503 inside the environmental simulation chamber 100. A suspension rope 505 is fixedly connected to the winding wheel 503, and the suspension rope 505 passes through each set of pulleys 502. A weight 501 is fixedly connected to the end of the suspension rope 505, and the weight 501 is located at the top of the environmental simulation chamber 100. In addition, the environmental simulation chamber 100 is equipped with a winding release component 504 in conjunction with the winding wheel 503. The winding release component 504 can release the traction force of the suspension rope 505, causing the weight 501 to fall due to gravity and impact the insulator. When the winding release component 504 is powered, it can also collect the suspension rope 505 to lift the weight 501 again. Furthermore, in this embodiment, please refer to Figure 12 , Figure 13 The take-up and release component 504 includes a spline sleeve 5041, a spline shaft 5042, a first drive gear 5043, a second drive gear 5044, a second worm 5045, a second worm wheel 5046, a spring 5047, and an electromagnet 5048. Specifically, the spline sleeve 5041 is fixedly connected to the axle of the take-up reel 503. The first drive gear 5043 is located inside the environmental simulation chamber 100 corresponding to the spline sleeve 5041. The spline shaft 5042 is fixedly connected to the first drive gear 5043, and the spline shaft 5042 cooperates with the spline sleeve 5041. A moving disc is rotatably connected to the first drive gear 5043. 5049, a motion column 5050 is fixedly connected to the motion disk 5049, a guide frame 5051 is fixedly connected inside the environmental simulation chamber 100, the motion column 5050 is slidably connected to the guide frame 5051, a spring 5047 is sleeved on the motion column 5050, one end of the spring 5047 is fixedly connected to the motion disk 5049, and the other end is fixedly connected to the guide frame 5051, an electromagnet 5048 is fixedly connected to the guide frame 5051, the electromagnet 5048 cooperates with the motion disk 5049, when the electromagnet 5048 attracts the motion disk 5049, the spline shaft 5042 disengages from the spline sleeve 5041; Inside the environmental simulation chamber 100, near the first drive gear 5043, a second drive gear 5044 is rotatably connected. The second drive gear 5044 meshes with the first drive gear 5043. A second worm gear 5046 is fixedly connected to the axle of the second drive gear 5044. Inside the environmental simulation chamber 100, a second worm 5045 is rotatably connected. The second worm 5045 meshes with the second worm gear 5046. When the weight 501 needs to be released, the electromagnet 5048 attracts the moving disc 5049. At this time, the spring 5047 is compressed, and the spline shaft 5042 disengages from the spline sleeve 5041. At this time, the take-up wheel 503 is released from the limiting force brought by the second worm 5045 and the second worm wheel 5046. The weight 501 can fall under the action of gravity, and the suspension rope 505 is wound out from the take-up wheel 503. When the weight 501 needs to be lifted again, the electromagnet 5048 is de-energized. Then, under the elastic force of the spring 5047, the moving disc 5049 drives the first drive gear 5043 to move towards the spline sleeve 5041, causing the spline shaft 5042 to insert into the spline sleeve 5041. The first drive gear 5043 meshes with the second drive gear 5044. When power is input to the second worm 5045, the second worm 5045 drives the second worm wheel 5046 to rotate, causing the second drive gear 5044 to drive the first drive gear 5043 to rotate. Ultimately, this causes the spline shaft 5042 to drive the spline sleeve 5041 to rotate. The winding wheel can wind up the lifting rope 505 to lift the weight 501. Because the moving disc 5049 is rotatably connected to the first drive gear 5043, when the first drive gear 5043 rotates, the moving disc 5049 will not rotate. That is, the moving disc 5049 only performs linear motion and does not perform rotational motion. In addition, the elastic force of the spring 5047 can provide a counterforce when the key and groove between the spline sleeve 5041 and the spline shaft 5042 do not correspond. After the first drive gear 5043 rotates a certain angle, when the key and groove correspond, the elastic force of the spring 5047 pushes the spline shaft 5042 into the spline sleeve 5041. Finally, please see Figure 2 , Figure 14 In order to provide the necessary power to the feeding and discharging mechanism 200 and the impact mechanism 500, a drive unit 600 is fixedly connected to the outside of the environmental simulation chamber 100. This avoids the electrical components being located inside the environmental simulation chamber 100 and prevents high temperature and high humidity from affecting the service life of the drive unit 600. Furthermore, the drive device 600 is powered by the reciprocating screw 202 in the feeding and discharging mechanism 200 through the first transmission structure 700, and the drive device 600 is powered by the winding and releasing component 504 in the impact mechanism 500 through the second transmission structure 800. Specifically, the drive device 600 is powered by the second worm gear 5045. The aforementioned first transmission structure 700 includes a second input shaft 701 and a first one-way transmission component 702. The power output end of the drive device 600 is fixedly connected to the second input shaft 701. The second input shaft 701 is poweredly connected to the reciprocating screw 202. The second input shaft 701 is provided with the first one-way transmission component 702, which is a first ratchet component. The aforementioned second transmission structure 800 includes a third input shaft 801 and a second one-way transmission component 802. The third input shaft 801 is poweredly connected to the second worm gear 5045. The second one-way transmission component 802 is provided on the third input shaft 801 and is a second ratchet component. The second input shaft 701 and the third input shaft 801 are connected by a belt drive 900, and the belt drive 900 is located on the power input side of the first one-way drive 702 and the second one-way drive 802. Under the action of the first one-way transmission component 702 and the second one-way transmission component 802, when the drive device 600 drives the reciprocating screw 202 to rotate, the drive device 600 cannot drive the second worm 5045 to rotate. When the drive device 600 drives the second worm 5045 to rotate, the drive device 600 cannot drive the reciprocating screw 202 to rotate. In other words, when the drive device 600 drives the feeding and discharging mechanism 200 to perform insulator feeding and discharging work, the impact mechanism 500 does not work. When the drive device 600 drives the impact mechanism 500 to work (to wind up the lifting rope 505), the feeding and discharging mechanism 200 does not work. With this structure, one set of drive devices 600 can achieve the required work, greatly reducing the power source and the required control components, thus reducing the failure rate of the device.

[0019] In summary, the insulator to be tested can be placed on the material support platform 204, and then the insulator is driven into the environmental simulation chamber 100 by the feeding and discharging mechanism 200. At the same time, the high-voltage electrode 302 contacts one end of the insulator's hardware, and the grounding electrode 303 contacts the other end of the insulator's hardware. The environment inside the environmental simulation chamber 100 can be adjusted to the test environment through the environmental simulation system, such as test temperature, humidity, voltage supplied to the insulator, and salt spraying onto the insulator. After the insulator has been in the test environment for a period of time, the insulator can be impacted by the impact mechanism 500. After the test is completed, the insulator can be transported out of the environmental simulation chamber 100 by the feeding and discharging mechanism 200. The aging resistance performance of the insulator can be judged by observing the surface condition of the insulator.
