Description

Technical Field

[0001] The invention belongs to the technical field of insulator electrical performance testing, and in particular relates to a device and method for electrical performance testing of GIS insulating basin insulators. Background Art

[0002] The electrical performance assessment of high-voltage insulation components is an important part of ensuring their safety and reliability in use. This assessment is mainly completed through high-voltage test equipment. The specific process includes installing the high-voltage insulation components on the test fixture, then placing them in a closed test tank, performing vacuuming and inflation operations, and connecting the test transformer to conduct power frequency withstand voltage test and partial discharge test.

[0003] In the existing operation mode, the mass of the pot-type insulator and its tooling are relatively large, and the assembly process is completely dependent on manual work. Workers need to place the tooling on the platform or the ground, and assemble it by bending over and other actions, and usually require the cooperation of multiple people to complete it. During the assembly process, the insulators need to be laid flat on the lower tooling one by one, and the electrodes are fastened with bolts, and then the upper tooling is moved to the insulator. Due to the large mass of the insulator and the tooling, workers need to bend over or take other laborious postures to operate, and usually require the cooperation of multiple people, which is laborious and hard to operate. The traditional tooling assembly process is cumbersome, and the insulators need to be laid flat one by one and fastened with bolts, resulting in low assembly efficiency. The traditional tooling needs to be fastened with bolts during assembly, which is easy to cause bumps, scratches and other damage to the insulating parts, conductor flanges, etc., thereby reducing their mechanical strength, electrical and insulation performance, and affecting the safety and reliability of the insulating parts. The traditional GIS insulator electrical performance test tooling usually adopts structures such as support plates, guide rails, sliders, and support frames. The insulators are fixed in a string through connecting tubes and spring locks, and connected in series through electrodes. However, this tooling has the following shortcomings: The assembly process is cumbersome, requiring multiple steps and tools, increasing the labor intensity and time cost. The movement of the pulley track is prone to failure, affecting the smooth progress of the test. The fixing method between the insulators is not stable enough, which is easy to cause displacement or loosening during the test. It cannot meet the strict quality requirements and surface quality requirements of high-voltage insulation tests.

[0004] In view of the low assembly efficiency and safety of existing high-voltage insulating parts, and the technical problems that the insulating parts are easily damaged during the assembly process, it is urgent to find a new device for electrical performance testing of GIS insulating basin insulators, which can make the processing process simple and fast, facilitate assembly, reduce the labor intensity of workers, and ensure the quality of insulating parts. Summary of the invention

[0005] In order to overcome the shortcomings of the above-mentioned prior art, the purpose of the present invention is to provide a device and method for electrical performance testing of GIS insulating pot insulators, so as to solve the technical problems of low assembly efficiency and low safety of existing high-voltage insulating parts, and easy damage to insulating parts during the assembly process.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: The invention discloses a device for testing the electrical performance of GIS insulating pot-type insulators, comprising: two support plates symmetrically arranged on both sides, a middle slide rail installed between the two support plates, and a trolley base installed below the middle slide rail; the pot-type insulator is uprightly installed on the middle slide rail, electrodes are arranged at the front and rear ends of the pot-type insulator, the front end of the electrode is connected to the convex conductor of one of the pot-type insulators, and the rear end of the electrode is arranged with a contact, which contacts the inner concave conductor of the other pot-type insulator to form a series circuit; a plurality of slide grooves are arranged on the support plates, and support rods are movably installed in the slide grooves; the middle slide rail cooperates with the support rod to support and guide the sliding of the pot-type insulator; and a clamping groove is arranged on the middle slide rail.

[0007] Preferably, the middle slide rail is a guide rail and slider type sliding assembly.

[0008] Preferably, a conductive conductor connecting mechanism is provided between the electrode and the pot-type insulator.

[0009] Preferably, the trolley base includes a plurality of support frames for supporting the middle slide rail.

[0010] Preferably, a plurality of limiting grooves for fixing the support rods are provided in the slide groove.

[0011] Preferably, the electrodes are detachably mounted at both ends of the pot-type insulator.

[0012] Preferably, the card slots are evenly distributed on the middle slide rail.

[0013] Preferably, the pot insulator is a component which slides along the guide rail.

[0014] Preferably, the support plate is fixedly mounted on the trolley base.

[0015] The present invention also discloses a method for using the above-mentioned device for testing the electrical performance of GIS insulating pot-type insulators, comprising the following steps: 1) Place the pot insulators to be tested on the middle slide rail in order, ensuring that each pot insulator is firmly supported; 2) Push the first pot-type insulator to the specified position and fix it by means of a slot-type fixing method; push the second pot-type insulator to the side of the first pot-type insulator to ensure that the center electrodes are aligned and connected; and so on, until all pot-type insulators are assembled; 3) Assemble one end of the conductive conductor to one end of the pot-type insulator and connect it to the conductor of the adjacent pot-type insulator through the contact to form a series circuit; 4) Start the test equipment, conduct electrical performance tests on the assembled pot-type insulators, record and analyze the results; after the test, disassemble the pot-type insulators in the reverse order of assembly.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The invention discloses a device for testing the electrical performance of GIS insulating pot-type insulators. The device abandons the original motion mode of pulley tracks and adopts a new central roller motion mode, thereby reducing the failure rate of the wheel motion mode, being simple and convenient to assemble, and the central axis is regularly coated with lubricating fluid, and the transportation smoothness is higher than that of the wheel motion mode. It is only necessary to assemble the left and right shields of a single pot-type insulator, and then the front and rear pot-type insulators can be contacted with each other, thereby simplifying the assembly process and method, and improving the tooling assembly rate. The symmetrically arranged support plates provide a stable support structure for the device, ensuring that the device will not tilt or collapse due to external forces during the test, thereby improving the safety and stability of the test. The middle slide rail serves as a sliding rail for the pot-type insulator, ensuring the linear sliding of the pot-type insulator during the test, thereby improving the accuracy and repeatability of the test. At the same time, the middle slide rail also plays a role in supporting the pot-type insulator. The trolley base provides mobility for the entire device, so that the device can be easily moved between different positions, thereby improving the flexibility and convenience of the test. The upright pot-type insulator makes the connection between the electrodes more direct and stable, thereby reducing the test error caused by poor connection. At the same time, the upright installation is also convenient for observation and operation. The setting of the electrode allows a series circuit to be formed between the pot-type insulators, which is convenient for electrical performance testing. At the same time, the electrode also serves as the current input and output point during the test and is an indispensable part of the test. This electrode connection method ensures the stable transmission of current between the pot-type insulators and improves the accuracy and reliability of the test. At the same time, the setting of the contact makes the connection between the electrode and the pot-type insulator more flexible and convenient. The design of the slide and support rod allows the support plate to be flexibly adjusted according to the test requirements to adapt to pot-type insulators of different sizes and specifications. At the same time, the movable support rod is also convenient for maintenance and replacement. The cooperation of the middle slide rail and the support rod makes the pot-type insulator more stable and smooth during the sliding process, reducing the test error caused by poor sliding. At the same time, this cooperation also improves the bearing capacity and stability of the device. The setting of the card slot allows the pot-type insulator to be firmly fixed after sliding to the specified position, avoiding the test error caused by position movement. At the same time, the card slot is also convenient for positioning and installation of the pot-type insulator. The guide rail sliding assembly is adopted, which can be erected on the assembly tool, and the two insulators are connected with the front and rear electrodes to realize sliding movement, that is, assemble one and move one; the conductive conductor is changed from the original two-end assembly to one-end assembly, and the contact is connected and turned on to form a series circuit. The design of contact connection and conduction makes the circuit connection simpler and faster, while ensuring the continuity and stability of the circuit. During the assembly process, the pot insulators are placed on the middle slide rail in sequence and assembled one by one. Whenever a pot insulator is assembled, it can slide along the guide rail to the next position, and start assembling the next pot insulator at the same time.As the assembly proceeds, when all the pot-type insulators of a car are assembled, the entire trolley can be moved along the guide rail to the next station for subsequent operations. One car is assembled and moved, realizing continuous flow operation, reducing waiting time and handling costs, and improving overall work efficiency. By setting a slot-type fixing method, it can be used as an intermediate positioning function and meet the requirements of rapid assembly. Using this structure, a single person can easily push two groups of products weighing nearly 80 kg each time, effectively reducing the labor intensity of manual labor and simplifying the operation of the tooling centering steps. Liberate workers from boring and heavy labor. The assembly can be easily realized, with the characteristics of simple processing and convenient maintenance. Originally, it was a roller with a high failure rate. Now this one-piece type similar to a bearing is convenient and simple. The guide rail sliding assembly can meet the strict quality requirements of high-voltage insulation tests and the strict surface quality requirements of high-voltage switch parts. It is suitable for three-phase pot-type insulators, and the size can be adjusted according to the size of the pot-type insulator. Adjustable support plates and slide rails are designed to adapt to pot-type insulators of different sizes and types. The present invention has a simple structure, is conducive to ensuring the quality of the product, and is easy to use and maintain.

[0017] The present invention also discloses a method for using the above-mentioned device for electrical performance testing of GIS insulating pot-type insulators. By adopting a guide rail slider sliding assembly mechanism and a new center roller motion mode, the assembly process of the insulator is smoother, the assembly time is reduced, and the overall assembly efficiency is improved. The application of the slot-type fixing method simplifies the assembly steps, reduces the complexity of the operation, and enables workers to complete the assembly work more quickly. The continuous flow assembly method eliminates the need for workers to frequently perform heavy physical labor, such as carrying and fixing insulators, thereby effectively reducing labor intensity. Each pot-type insulator only needs to be pushed together in the center and the center electrode is connected, and no additional fixing process is required, which reduces safety hazards in the assembly process and improves work safety. The guide rail slider sliding assembly mechanism ensures the stable movement of the insulator in the centering state and avoids test errors caused by position deviation. The conductive conductor connection mechanism ensures good contact between the electrode and the insulator, and improves the accuracy and reliability of the electrical performance test. The device has a simple structure, is easy to maintain and maintain, and reduces maintenance costs. The application of the center roller motion mode and the slot-type fixing method reduces the wear and damage of components and extends the service life of the device.
