Description

Technical Field

[0001] This invention relates to the field of insulating rod testing, and more particularly to an insulating rod testing device and method for electroscopes. Background Technology

[0002] In the field of power equipment testing, voltage detectors are crucial tools for ensuring electrical work safety, and the reliability of their insulation performance is paramount. The insulation quality of the voltage detector's insulating rod directly affects its ability to accurately detect live conditions, thus impacting the personal safety of operators and the stable operation of the power system. Currently, there are certain limitations in the detection devices and methods for the insulating rods of voltage detectors. For example, the invention patent with publication number CN116679176A is a single, non-continuous detection, which makes continuous detection inefficient and difficult to meet the needs of large-scale, high-frequency detection scenarios. On the other hand, in practical applications, the insulating rod of the voltage detector may be used in scenarios where insulation performance is reduced, such as harsh environments with high temperature and high humidity. If the impact of these special environments on insulation performance cannot be effectively simulated, the insulation performance of the insulating rod that has passed the conventional test may be greatly reduced when it encounters high temperature and high humidity conditions in actual use, and may even cause safety accidents. Summary of the Invention

[0003] The purpose of this invention is to address the shortcomings of existing technologies by proposing an electrical detector insulation rod testing device and method. In practical use, this solution can achieve continuous testing, improving testing efficiency. In addition, during the testing process, it can simulate insulation testing under high temperature and high humidity conditions, making it more suitable for actual testing needs.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: An electroscope insulating rod testing device includes a frame and a testing cylinder mounted on the upper part of the frame. The bottom of the testing cylinder is filled with water. A notch is formed on the left side wall of the testing cylinder. A rotating shaft is rotatably connected between the front and rear inner walls of the testing cylinder. Four sets of drive rods are circumferentially mounted on the outside of the rotating shaft. Each drive rod has an arc-shaped baffle plate that passes through and is fixedly connected to it. Each end of the drive rod is equipped with a placement component for placing the insulating rod body. The four arc-shaped baffle plates, together with the testing cylinder, form a material handling area, a cleaning area, a high-temperature and high-humidity testing area, and a normal-temperature and normal-humidity testing area. Four zones are equally spaced counterclockwise along the inside of the detection cylinder. A drive motor is installed on the front side of the detection cylinder, and the output shaft of the drive motor extends into the inside of the detection cylinder and is fixedly connected to the rotating shaft. As the drive motor starts intermittently, the main body of the insulating rod will pass through the material handling area, the cleaning area, the high temperature and high humidity detection area, and the normal temperature and humidity detection area in sequence, forming a complete detection path. Finally, the material is unloaded in the material handling area to achieve continuous detection. An intermittent air supply component is installed on the detection cylinder to simultaneously clean the cleaning area and create the environment for the high temperature and high humidity detection area and the normal temperature and humidity detection area.

[0005] Preferably, the placement assembly includes a rotating tube extending through the end of the drive rod from front to back, the rotating tube being rotatably connected to the drive rod, and an annular rubber damping layer for increasing damping is provided on the inner side of the rotating tube.

[0006] Preferably, the inner wall of the detection cylinder is fixedly connected with three arc-shaped racks, each of the rotating tubes is fixedly sleeved with a torsion spring on its outer side, the other end of each torsion spring is fixedly connected to the front side of the drive rod, and each of the rotating tubes is fixedly sleeved with a drive gear.

[0007] Preferably, a pad is fixedly connected to the rear part of the notch, the front side of the pad is flush with the rear inner wall of the detection cylinder, and the front and rear side walls of each arc-shaped baffle are in contact with the front and rear inner walls of the detection cylinder and are slidably connected.

[0008] Preferably, circular grooves are provided on the front and rear inner walls of the right and top regions of the detection cylinder, and an electrical contact is slidably connected in each circular groove. One side of each electrical contact is elastically connected to the inner wall of the corresponding circular groove through a first spring. Two electromagnets are fixedly connected to the front and rear sides of the detection cylinder. A permanent magnet is embedded in each electrical contact. When each electromagnet is energized, it repels the adjacent surface of the corresponding permanent magnet.

[0009] Preferably, the intermittent gas supply assembly includes a connecting column fixedly connected to the lower end of the frame platform. A cylindrical groove is formed at the platform and the upper end of the connecting column. A piston plate is slidably connected in the cylindrical groove. The lower end of the piston plate is elastically connected to the inner bottom of the cylindrical groove through a second spring. The bottom space of the cylindrical groove is connected to the outside through a one-way port. A one-way pipe is connected to the bottom space of the cylindrical groove. Hollow columns are fixedly connected to the upper, lower, and right sides of the detection cylinder. Each hollow column is connected to the inside of the detection cylinder through a strip-shaped port. An electric heating wire is installed in the hollow column located on the right side. Multiple exhaust ports are formed on the top side wall and the right side wall of the detection cylinder. The other end of the one-way pipe is connected to an annular pipe. The annular pipe is connected to the inside of the corresponding hollow column through multiple branch pipes.

[0010] Preferably, both the one-way port and the one-way pipe are equipped with one-way valves. The flow direction of the one-way valve inside the one-way port is one-way from the outside to the inside of the cylindrical groove, and the flow direction of the one-way valve inside the one-way pipe is one-way from the cylindrical groove to the annular pipe.

[0011] Preferably, a gearbox is installed on the rear side wall of the detection cylinder, the input end of the gearbox extends into the inside of the detection cylinder and is fixedly connected to the rear end of the rotating shaft, the output shaft of the gearbox is fixedly connected to an incomplete gear, and the upper end of the piston plate is fixedly connected to a vertical rack that meshes with the incomplete gear.

[0012] Preferably, a circulation pump and a filter box are fixedly connected to the lower end of the platform of the frame. The front space of the filter box is connected to the front space of the detection cylinder through an inlet pipe. The rear space of the filter box is connected to the inlet end of the circulation pump. The outlet end of the circulation pump is connected to the rear space of the detection cylinder.

[0013] This invention also discloses a voltage testing method using an insulated rod testing device for voltage detectors, comprising the following steps: Step 1: Insert the insulating rod of the voltage detector without the handle into the rotating tube at the end of the drive rod inside the detection cylinder. Use the annular rubber damping layer to limit the movement, so that the rear end of the insulating rod contacts the pad, and the installation is completed. Step 2: Start the drive motor to drive the rotating shaft and drive rod to rotate, so that the insulating rod passes through each detection area in sequence. The gearbox amplifies the rotation, and the incomplete gear realizes the piston plate to move up and down to extract gas. While cleaning, the corresponding area is created with environmental conditions. Step 4: The drive motor and electromagnet start alternately. When the insulating rod enters the high temperature and high humidity detection zone and the normal temperature and normal humidity detection zone, the electrical contact extends to contact the insulating rod to realize the detection. Finally, the material is unloaded in the material handling area. Step 5: Periodically start the circulation pump. The water in front of the detection cylinder enters the filter box through the inlet pipe, is filtered, and then returns to the rear space, realizing the self-cleaning of the internal water and ensuring the cleanliness of the water.

[0014] Compared with the prior art, the beneficial effects of this invention are as follows: 1. The drive motor rotates the shaft, causing the insulating rod to pass through different detection zones sequentially. The gearbox amplifies the rotation, allowing the incomplete gears to complete a single rotation, achieving orderly switching between zones and ensuring that the insulating rod can undergo comprehensive testing in different environments, thus improving detection efficiency and completeness.

[0015] 2. Incomplete gear meshing with a vertical rack causes the piston plate to move up and down within a cylindrical groove, enabling gas intake and exhaust through a one-way port and tube. A heating wire heats the gas, and airflow is forced into the hollow column at different positions, achieving self-cleaning and creating various testing environments, including high-temperature / high-humidity and normal-temperature / normal-humidity.

[0016] 3. The rotating tube holding the insulating rod rotates as it passes the arc-shaped rack, and then rotates back and forth in both directions after disengaging. It achieves self-cleaning in the clean zone, improving cleaning efficiency; dehydrates and evenly dries and heats in the high-temperature and high-humidity testing zone; and evenly cools and simulates the environment in the normal-temperature and normal-humidity testing zone, enhancing testing accuracy.

[0017] 4. The drive motor and electromagnet start alternately. When the insulating rod enters the specific detection area, the electrical contacts extend under the repulsion of like poles and contact the two ends of the insulating rod to achieve detection. This improves the stability of electrical contact without interfering with movement.

[0018] 5. Continuous testing is possible. Initially, an insulating rod is placed in the material handling area. Each time the drive motor starts, different areas are processed sequentially, and new insulating rods can be placed in the material handling area simultaneously. Simultaneous processing and testing in multiple areas effectively improves actual testing efficiency and meets the needs of large-scale testing.

[0019] 6. Periodically start the circulation pump to circulate the water in the testing cylinder after filtration through the filter box, achieving self-cleaning of the water. This ensures water cleanliness and prevents water pollution from affecting the cleaning effect on the insulating rod in the clean area, thereby guaranteeing the accuracy and stability of the entire testing process.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0024] Reference Figures 1-9 An electroscope insulating rod testing device includes a frame 1, characterized in that it also includes a testing cylinder 2 set at the upper end of the frame 1. The bottom of the testing cylinder 2 is filled with water, the height of which is one-third of the height of the testing cylinder 2. A notch 6 is provided on the left side wall of the testing cylinder 2. In specific operation, the material is fed into the notch 6. A rotating shaft 18 is rotatably connected between the front and rear inner walls of the testing cylinder 2. It also includes four sets of drive rods 19 circumferentially installed on the outside of the rotating shaft 18. Each drive rod 19 is connected to an arc-shaped baffle plate 27. Each drive rod 19 has a placement assembly for placing the main body of the insulating rod installed at its end. The placement assembly includes a rotating tube 29 that runs through the ends of the drive rod 19. The rotating tube 29 is rotatably connected to the drive rod 19. The inner side of the rotating tube 29 is provided with an annular rubber damping layer for increasing damping. When placing the rod, the insulating rod is simply inserted into the rotating tube 29 and the annular rubber damping layer is used to limit the position of the insulating rod. The four arc-shaped baffles 27, together with the detection cylinder 2, form a material handling area, a cleaning area, a high-temperature and high-humidity detection area, and a normal-temperature and normal-humidity detection area. The four areas are equally spaced in a counterclockwise direction inside the detection cylinder 2. A drive motor 3 is installed on the front side of the detection cylinder 2. The output shaft of the drive motor 3 extends into the detection cylinder 2 and is fixedly connected to the rotating shaft 18. As the drive motor 3 is started intermittently, the main body of the insulating rod will pass through the material handling area, the cleaning area, the high-temperature and high-humidity detection area, and the normal-temperature and normal-humidity detection area in sequence, forming a complete detection path. Finally, the material is unloaded in the material handling area to achieve continuous detection. Among them, a pad 7 is fixedly connected to the groove opening on the rear side of the notch 6. The front side of the pad 7 is flush with the rear inner wall of the detection cylinder 2. When installing the insulating rod, it is sufficient for the rear end of the insulating rod to contact the pad 7 to indicate that the installation is in place. In addition, the insulating rod to be tested is the rod structure of the electroscope without the handle. The front and rear side walls of each arc-shaped shield 27 are in contact with the front and rear inner walls of the detection cylinder 2 and are slidably connected.

[0025] The detection cylinder 2 is equipped with an intermittent air supply component. The intermittent air supply component is used to simultaneously clean the clean area and create the environment of the high temperature and high humidity detection area and the normal temperature and normal humidity detection area. The intermittent air supply component includes a connecting column 12 fixedly connected to the lower end of the platform of the frame 1. The platform of the connecting column 12 and the upper end of the connecting column 12 are provided with a cylindrical groove. A piston plate 25 is slidably connected in the cylindrical groove. The lower end of the piston plate 25 is elastically connected to the inner bottom of the cylindrical groove through a second spring 26. The bottom space of the cylindrical groove is connected to the outside through a one-way port 13. A one-way pipe 14 is connected to the bottom space of the cylindrical groove. Hollow columns 8 are fixedly connected to the upper, lower and right sides of the detection cylinder 2. Each hollow column 8 is connected to the inside of the detection cylinder 2 through a strip-shaped port. An electric heating wire 20 is installed in the hollow column 8 located on the right side. Multiple exhaust ports 10 are provided on the top side wall and the right side wall of the detection cylinder 2. The other end of the one-way pipe 14 is connected to an annular pipe 11. The annular pipe 11 is connected to the interior of the corresponding hollow column 8 through multiple branch pipes. One-way valves are installed inside the one-way port 13 and the one-way pipe 14. The flow direction of the one-way valve inside the one-way port 13 is one-way from the outside to the inside of the cylindrical groove. The flow direction of the one-way valve inside the one-way pipe 14 is one-way from the cylindrical groove to the annular pipe 11. In this way, when the vertical rack 17 moves up and then down with the piston plate 25, gas can be drawn in through the one-way port 13 first, and then the gas can be forced out through the one-way pipe 14.

[0026] In this design, a gearbox 16 is installed on the rear wall of the detection cylinder 2. The input end of the gearbox 16 extends into the inside of the detection cylinder 2 and is fixedly connected to the rear end of the rotating shaft 18. An incomplete gear 15 is fixedly connected to the output shaft of the gearbox 16. A vertical rack 17 that cooperates with the incomplete gear 15 is fixedly connected to the upper end of the piston plate 25. Furthermore, in this design, the drive motor 3 rotates one-quarter of a turn each time it starts, while the gearbox 16 can amplify the rotation of the rotating shaft 18 by four times. That is, each time the drive motor 3 starts, the incomplete gear 15 completes a single rotation.

[0027] The inner wall of the detection cylinder 2 is fixedly connected with three arc-shaped racks 21. Each rotating tube 29 is fixedly sleeved with a torsion spring 30 on its outer side. The other end of each torsion spring 30 is fixedly connected to the front side of the drive rod 19. Each rotating tube 29 is fixedly sleeved with a drive gear 31. By using multiple arc-shaped racks 21, when the rotating tube 29 with the insulating rod enters the cleaning area from the material handling area, enters the high temperature and high humidity detection area from the cleaning area, and enters the normal temperature and humidity detection area from the high temperature and high humidity detection area, the rotating tube 29 will rotate when passing through the arc-shaped racks 21, causing the torsion springs 30 to contract. After entering the corresponding area, that is, after disengaging from the corresponding arc-shaped rack 21, the rotating tube 29 can rotate back and forth in both directions multiple times under the elastic action of the torsion spring 30 and its own inertia. The reciprocating rotation in the clean zone first rotates relative to the water body, achieving self-cleaning. The horizontal floating in the water then provides a more comprehensive impact on the insulating rod, improving the cleaning effect. The reciprocating rotation in the high temperature and high humidity detection zone first utilizes centrifugal force for dehydration. After the high temperature airflow is blown out, it can evenly contact the insulating rod, rapidly and evenly heating its surface. At this time, the high temperature and high humidity detection zone is in a high temperature and high humidity environment. The reciprocating rotation in the normal temperature and humidity detection zone allows the insulating rod to evenly contact the normal temperature airflow, which cools it evenly. At the same time, the airflow can carry out the high temperature and humid gas in the space enclosed by the arc-shaped baffle 27 and the inner wall of the detection cylinder 2, achieving a simulation of a normal temperature and humidity environment.

[0028] The detection cylinder 2 has circular grooves 22 on the front and rear inner walls of the right and top areas (corresponding to the high temperature and high humidity detection area and the normal temperature and normal humidity detection area). Each circular groove 22 is slidably connected to an electrical contact 23. One side of each electrical contact 23 is elastically connected to the inner wall of the corresponding circular groove 22 through a first spring 24. Two electromagnets 9 are fixedly connected to the front and rear sides of the detection cylinder 2. Each electrical contact 23 is embedded with a permanent magnet. When each electromagnet 9 is energized, it repels the adjacent surface of the corresponding permanent magnet. When the drive motor 3 is started, the electromagnet 9 is turned off. When the drive motor 3 is de-energized, the electromagnet 9 is started. The two start alternately. Furthermore, a set of electrical contacts 23 is symmetrically arranged in pairs and connected to the external detection system. When the rear electrical contact 23 contacts the rear end of the insulating rod and the front electrical contact 23 contacts the front end of the insulating rod, the detection operation can be realized. The lower end of the platform of the frame 1 is fixedly connected to a circulation pump 32 and a filter box 4. The front space of the filter box 4 is connected to the front space of the detection cylinder 2 through the liquid inlet pipe 5. The rear space of the filter box 4 is connected to the liquid inlet of the circulation pump 32, and the liquid outlet of the circulation pump 32 is connected to the rear space of the detection cylinder 2. The circulation pump 32 can be started periodically. In conjunction with the filter box 4, the internal water can be self-cleaned to ensure the cleanliness of the water. The filter box 4 is equipped with a filter element for filtration. This is existing technology and will not be described in detail here.

[0029] In this invention, the insulating rod of the electroscope rod structure without the handle is inserted into the rotating tube 29 at the end of the drive rod 19 inside the detection cylinder 2. The annular rubber damping layer on the inner side of the rotating tube 29 limits the insulating rod, so that the rear end of the insulating rod contacts the pad 7 at the rear part of the notch 6, thus completing the installation. The drive motor 3 on the front side of the detection cylinder 2 is started. The output shaft of the drive motor 3 drives the rotating shaft 18 to rotate, and the drive rod 19 on the rotating shaft 18 rotates accordingly, so that the main body of the insulating rod passes through the material handling area, the cleaning area, the high temperature and high humidity detection area, and the normal temperature and humidity detection area in sequence. Each time the drive motor 3 starts, it rotates one-quarter revolution. The gearbox 16 on the rear side wall of the detection cylinder 2 amplifies the rotation of the rotating shaft 18 by four times, so that the incomplete gear 15 fixed on the output shaft of the gearbox 16 just completes a single rotation. When the incomplete gear 15 rotates, its teeth intermittently mesh with the vertical rack 17. Under the elastic action of the second spring 26, it moves upward and then downward, causing the piston plate 25 to move upward and then downward within the cylindrical groove. When moving upward, gas is drawn in from the outside through the one-way port 13; when moving downward, the gas is forced into the annular pipe 11 through the one-way pipe 14, and then enters the hollow column 8 through the branch pipe. At the same time, the heating wire 20 located in the hollow column 8 on the right side is in an activated state, which can heat the incoming gas. Further, after the airflow is blown into the hollow column 8 at the bottom, the airflow enters the water body through the strip-shaped port and floats upward in the form of bubbles. After the airflow is blown into the hollow column 8 on the right side, the airflow is discharged through the strip-shaped port, which can dry and heat the insulating rod. After the airflow is blown into the hollow column 8 on the upper side, it can cool the hotter insulating rod. At the same time, room temperature gas is used to replace the original high temperature and high humidity gas. In addition, when the rotating tube 29, which contains the insulating rod, enters the cleaning zone from the material handling area, the high-temperature and high-humidity detection zone from the cleaning zone, and the normal temperature and humidity detection zone from the high-temperature and high-humidity detection zone, it passes through the arc-shaped rack 21 on the inner wall of the detection cylinder 2, and the drive gear 31 drives the rotating tube 29 to rotate, causing the torsion spring 30 to contract. After entering the corresponding area and disengaging from the arc-shaped rack 21, the rotating tube 29 rotates back and forth repeatedly in both directions under the elastic action of the torsion spring 30 and its own inertia. In the cleaning zone, the rotation causes the insulating rod to rotate relative to the water body to achieve self-cleaning, and the water floating impacts the insulating rod to improve the cleaning effect; in the high-temperature and high-humidity detection zone, centrifugal force is used for dehydration, and the high-temperature airflow evenly contacts the insulating rod for rapid and uniform drying and heating; in the normal temperature and humidity detection zone, the insulating rod is evenly contacted by the normal temperature airflow for uniform cooling, while the high-temperature and humid gas is carried out to simulate the normal temperature and humidity environment; When the drive motor 3 starts, the electromagnet 9 is turned off; after the drive motor 3 is de-energized, the electromagnet 9 starts, and the two alternate. Every two electrical contacts 23 arranged symmetrically front to back are connected to the external detection system. When the insulating rod enters the high temperature and high humidity detection zone and the normal temperature and normal humidity detection zone, under the repulsive action of the like poles of the permanent magnet block inside the electromagnet 9 and the electrical contact 23, the electrical contact 23 extends. The detection operation is realized when the rear electrical contact 23 contacts the rear end of the insulating rod and the front electrical contact 23 contacts the front end of the insulating rod. The insulating rod is finally unloaded in the material handling area. In specific testing operations, continuous testing can be performed. Initially, the insulating rod is placed in the material handling area. Then, after the drive motor 3 is started once, it rotates to the clean area. At the same time, another insulating rod is placed in the material handling area. After the drive motor 3 is started once more, high temperature and high humidity environment monitoring can be performed. Then, another insulating rod is placed in the material handling area. The above process is repeated to ensure that multiple areas can be processed and tested simultaneously. Finally, the tested insulating rod is removed from the material handling area, and then the insulating rod to be tested is placed in. The entire testing process has good continuity, which can effectively improve the actual testing efficiency during continuous testing operations. In addition, the circulation pump 32 at the lower end of the platform of the frame 1 can be started periodically. The water in the front space of the detection cylinder 2 enters the filter box 4 through the inlet pipe 5. After being filtered by the filter element in the filter box 4, it returns to the rear space of the detection cylinder 2 from the rear space of the filter box 4 through the outlet of the circulation pump 32, so as to realize the self-cleaning of the internal water and ensure the cleanliness of the water.

[0030] This invention also discloses a voltage testing method using an insulated rod testing device for voltage detectors, comprising the following steps: Step 1: Insert the insulating rod of the voltage detector without the handle into the rotating tube 29 at the end of the drive rod 19 inside the detection cylinder 2. Use the annular rubber damping layer to limit the movement, so that the rear end of the insulating rod contacts the pad 7, and the installation is completed. Step 2: Start the drive motor 3 to drive the rotating shaft 18 and drive rod 19 to rotate, so that the insulating rod passes through each detection area in sequence. The gearbox 16 amplifies the rotation, and the incomplete gear 15 realizes the piston plate 25 to move up and down to pump gas. While cleaning, the corresponding area is created environmentally. Step 4: The drive motor 3 and the electromagnet 9 start alternately. When the insulating rod enters the high temperature and high humidity detection zone and the normal temperature and normal humidity detection zone, the electrical contact 23 extends to contact the insulating rod to realize the detection. Finally, the material is unloaded in the material handling area. Step 5: Periodically start the circulation pump 32. The water in front of the detection cylinder 2 enters the filter box 4 through the liquid inlet pipe 5 and then returns to the rear space, realizing the self-cleaning of the internal water and ensuring the cleanliness of the water.
