Description

Technical Field

[0001] This utility model belongs to the technical field of high-voltage test platforms, and particularly relates to a high-voltage test platform device with a hinged, detachable and combined equalizing ring. Background Technology

[0002] A high-voltage test platform is a specialized device used for testing high-voltage electrical equipment and components. It is primarily used to verify the performance and safety of electrical equipment under high-voltage environments. With the continuous development of power systems, the application of various high-voltage equipment such as transformers, circuit breakers, insulators, and other high-voltage components is becoming increasingly widespread, leading to the development of high-voltage test platforms. This platform typically simulates various high-voltage environments that equipment may face in actual operation, ensuring its safe and reliable operation under all conditions. The design of a high-voltage test platform must not only withstand high-voltage current but also consider the operational safety and testing accuracy of the equipment.

[0003] In high-voltage testing platforms, equalizing rings are crucial components, primarily designed to enhance the safety and stability of the testing process. The function of an equalizing ring is to distribute the voltage applied to the test object evenly, thereby preventing damage to the testing equipment or the object under test due to voltage concentration. Specifically, by increasing the uniformity of the electric field, equalizing rings effectively reduce voltage spikes in localized areas, thus minimizing the risk of corona discharge and partial discharge.

[0004] During high-voltage testing, the equipment under test is often placed in a strong electric field. The arrangement of equalizing rings can absorb the non-uniformity of the electric field distribution to a certain extent, forming a more balanced electric field and ensuring the accuracy and repeatability of test data. In addition, the application of equalizing rings can extend the service life of high-voltage equipment and improve its safety; therefore, its importance cannot be ignored.

[0005] While equipotential bonding rings play an indispensable role in high-voltage testing platforms, their large size is a significant issue. This size is designed to effectively handle and disperse the high-voltage electric field, resulting in a more uniform distribution of electric field lines. However, the large size of equipotential bonding rings presents numerous inconveniences in actual operation and transportation. Equipotential bonding rings often require custom manufacturing to ensure compatibility with the testing equipment, meaning their size may far exceed the volume limits of general transport equipment. This necessitates the use of specialized transport vehicles, increasing logistics costs and time. Secondly, the installation and disassembly of equipotential bonding rings during high-voltage testing are also quite complex. Large equipotential bonding rings often require multiple workers to operate simultaneously, increasing labor intensity and safety risks. Improper handling of such a large component can easily damage equipment and injure personnel. Utility Model Content

[0006] The technical problem to be solved by this utility model is to provide a high-pressure test platform device with a hinged, detachable and combined equalizing ring, which addresses the shortcomings of the existing devices.

[0007] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0008] A high-pressure test platform device with a hinged, detachable, and modular equalizing ring includes a load-bearing unit and a high-pressure test unit. End A of the high-pressure test unit is hinged to the load-bearing unit, and end B of the high-pressure test unit is fitted with an equalizing ring structure. The equalizing ring structure includes an upper equalizing ring unit and a lower equalizing ring unit. The upper equalizing ring unit includes an upper half-ring and a hinged structure, which is hinged to end B of the high-pressure test unit. The lower equalizing ring unit includes a lower half-ring and a fixing structure, which is detachably fixed to end B of the high-pressure test unit. The upper and lower half-rings together form a split equalizing ring, and the upper half-ring can rotate to the position of the lower half-ring via the hinged structure.

[0009] To optimize the above technical solution, the specific measures also include:

[0010] The aforementioned support unit includes a support platform body and electric support legs. The support platform body is a flat plate structure, and the electric support legs are fixedly installed at the four corners of the support platform body. The lower ends of the electric support legs can support the ground, allowing the support platform body to be off the ground.

[0011] The aforementioned high-voltage test unit includes a frequency converter, an excitation transformer, and a resonant reactor. The frequency converter, excitation transformer, and resonant reactor are all installed on the bearing unit. The frequency converter, excitation transformer, and resonant reactor are connected in sequence. The A end of the high-voltage test unit is the rear end of the resonant reactor, and the B end of the high-voltage test unit is the front end of the resonant reactor.

[0012] The aforementioned resonant reactor is further provided with a rotating base and a drive cylinder at its rear end. The rotating base is hinged to the rear end of the resonant reactor and is fixedly mounted on the support unit. The drive cylinder is mounted on the support unit and its drive shaft is connected to the resonant reactor. The drive cylinder can push the resonant reactor to rotate around the rotating base, thereby allowing the resonant reactor to switch between horizontal and vertical states.

[0013] The hinge structure of the aforementioned upper equalizing ring unit includes a hinge frame and a hinge seat. The hinge frame is fixedly connected to the upper half ring, and the hinge seat is fixed at the middle of the front end of the resonant reactor. The hinge frame and the hinge seat are hinged together.

[0014] The upper half ring is equipped with a fixing block, which allows the upper half ring to be fixedly connected to the rear end of the resonant reactor via the fixing block.

[0015] The aforementioned fixing structure of the lower equalizing ring unit includes a fixing frame and fasteners. The fixing frame is fixedly connected to the lower half ring, and the fixing frame is detachably fixed to the middle of the front end of the resonant reactor by the fasteners.

[0016] Both the upper and lower halves of the ring are made of aluminum or aluminum alloy.

[0017] The upper and lower halves of the ring are hollow inside.

[0018] The aforementioned support platform body is provided with a storage area for the lower equalizing ring unit. When the lower equalizing ring unit is removed from the front end of the resonant reactor, the lower equalizing ring unit can be placed in the storage area of ​​the lower equalizing ring unit.

[0019] The beneficial effects of this utility model are:

[0020] 1. The high-pressure test platform device of this utility model has improved the structure of the equalizing ring by dividing the original large-volume equalizing ring into two parts (each half ring weighs 70.5 kg), thus dispersing the overall weight of the equalizing ring, so that it can be installed manually and put into use more conveniently and quickly.

[0021] 2. This utility model uses a hinged, disassembly and assembly method to fold up the equalizing ring. The equalizing ring has an outer diameter of 3100mm. When not folded up, the equalizing ring is too tall to pass through some height-restricted bridges. The upper equalizing ring unit itself is also tall, and each disassembly requires workers to work at height, which poses a safety risk. Therefore, this utility model adopts the method of disassembling the lower equalizing ring unit and then rotating the upper equalizing ring unit to the position of the lower equalizing ring unit. This solves the problem of the equalizing ring being too tall during transportation and also solves the problem of needing to work at height during the disassembly and assembly of the equalizing ring. It can greatly reduce the difficulty of transporting, installing and disassembling the equalizing ring. Attached Figure Description

[0032] like Figure 1-5 As shown, the main structure of this utility model includes a bearing unit 4, a high-voltage test unit 5, and an equalizing ring structure 1. The bearing unit 4 includes a bearing platform body 41 and an electric support leg 42. The bearing platform body 41 is generally installed on a specially designed transport vehicle, and the electric support leg 42 is used to support the entire bearing platform body 41 so that the high-voltage test platform device can be effectively fixed on the ground when it is working.

[0033] The high-voltage test unit 5 is mounted on the support platform body 41 and includes a variable frequency power supply 51, an excitation transformer 52, a resonant reactor 53, a rotating base 54, and a drive cylinder 55. The variable frequency power supply 51 is mainly used to provide adjustable high-voltage power for high-voltage insulation testing and withstand voltage testing. The excitation transformer 52 is used to provide a specific excitation voltage to ensure the normal operation and testing of electrical equipment (such as generators and transformers). The resonant reactor 53 is an important component in the high-voltage test platform, mainly used to control the resonance phenomenon during voltage rise. Its functions include: tuning function: The resonant reactor can form a resonant circuit with the test equipment, thereby achieving a larger voltage amplitude at a specific frequency, helping to improve test efficiency, especially when performing partial discharge or withstand voltage tests. Harmonic suppression: In high-voltage testing, harmonics can adversely affect measurement results. The resonant reactor can effectively suppress harmonics, reduce the influence of nonlinear loads on the test, improve signal purity, and ensure the accuracy of test results. Voltage dividing function: In high-voltage testing, the resonant reactor can distribute the voltage, reduce the instantaneous voltage surges that the equipment is subjected to, and protect the test equipment and the object under test.

[0034] The resonant reactor 53 is 3.5-6 meters long. It is in working condition when erected and in non-working condition when laid horizontally. The rotating base 54 is involved in the hinged connection of the rear end of the resonant reactor 53. The rotating base 54 is fixedly installed on the support unit 4. The drive cylinder 55 is installed on the support unit 4. The drive shaft of the drive cylinder 55 is connected to the resonant reactor 53. The drive cylinder 55 can push the resonant reactor 53 to rotate around the rotating base 54, thereby switching the resonant reactor 53 between horizontal and vertical states.

[0035] The key modification of this utility model lies in the equalizing ring structure 1 installed at the front end of the resonant reactor 53. In this embodiment, the front end refers to... Figure 1 The left end of the resonant reactor 53 is shown. This invention divides the equalizing ring structure 1 into upper and lower equalizing ring units. The upper equalizing ring unit 2 includes an upper half-ring 21, a hinge frame 22, and a hinge seat 23. The hinge frame 22 is fixedly connected to the upper half-ring 21, and the hinge seat 23 is fixed to the middle of the front end of the resonant reactor 53. The upper half-ring 21 is hinged together by the hinge frame 22 and the hinge seat 23. The lower equalizing ring unit 3 includes a lower half-ring 31 and a fixing frame 32. The fixing frame 32 is fixedly connected to the lower half-ring 31 and is detachably fixed to the middle of the front end of the resonant reactor 53 by fasteners.

[0036] The high-pressure test platform is in the deployed state during use, such as... Figure 1-2 As shown, at this time, the upper half ring 21 is rotated to the upper end, and the lower half ring 31 is fixed to the middle of the front end of the resonant reactor 53 by fasteners. After installation, the resonant reactor 53 is rotated to a vertical position by the drive cylinder 55, and then a high-voltage test is performed.

[0037] The high-voltage testing platform was transported in a disassembled and folded state, such as... Figure 4-5 As shown, at this time, the upper half ring 21 is rotated to the lower end, and the lower half ring 31 is disassembled and placed on the bearing platform body 41. At this time, the height of the equalizing ring structure 1 is greatly reduced, which facilitates the transportation of the high-pressure test platform device.

[0038] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope.
