Description
Technical Field
[0001] This utility model belongs to the technical field of high-pressure test platforms, and particularly relates to a variable diameter rotating equalizing ring structure. Background Technology
[0002] A high-voltage test platform is a device used for high-voltage and high-current testing, widely used in the power industry, electronic component manufacturing, and the research and development and production of various high-voltage electrical appliances. The main functions of this type of platform include insulation strength testing, withstand voltage testing, and operational testing of power equipment, insulating materials, and electrical components to determine their safety performance and operational reliability under high-voltage environments.
[0003] High-voltage testing platforms are typically equipped with high-voltage generators, measuring instruments, and control systems, capable of simulating various electrical operating conditions and testing equipment performance under high voltage. This is crucial for ensuring the safety and effectiveness of equipment, particularly in power transmission, substation construction, and compliance testing of electrical products.
[0004] The vehicle-mounted high-voltage test platform is a portable device improved upon the existing high-voltage test platform. Its main feature is the integration of high-voltage testing equipment inside the vehicle, enabling direct on-site testing and greatly enhancing the flexibility and convenience of testing operations. The vehicle-mounted high-voltage test platform is particularly suitable for the maintenance and installation of power facilities, as well as emergency response to unforeseen events.
[0005] Vehicle-mounted high-voltage testing platforms allow personnel to quickly reach the site and conduct high-voltage tests, saving time and labor costs. Furthermore, vehicle-mounted platforms typically possess excellent shock resistance and protective measures, enabling stable operation in various complex environments, thus ensuring the accuracy and safety of test results.
[0006] In high-voltage testing, the equalizing ring is an important component, mainly used to ensure the uniform distribution of test current in different parts, so as to avoid local overheating or arcing caused by uneven current.
[0007] Although equipotential bonding rings play a crucial role in high-pressure testing, their current large size causes inconvenience during transportation and use. Large equipotential bonding rings are difficult to arrange and operate effectively in space-constrained environments. Users often face limitations when handling and installing equipotential bonding rings on-site, increasing labor and time costs.
[0008] Therefore, developing smaller and more optimized equalizing rings has become an important task for the industry. Utility Model Content
[0009] The technical problem to be solved by this utility model is to provide a variable diameter rotating pressure equalizing ring structure to address the shortcomings of the existing structure.
[0010] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:
[0011] A variable-diameter rotating equalizing ring structure includes an upper horizontal platform, a lower horizontal platform, an upper equalizing ring unit, and a lower equalizing ring unit. The upper horizontal platform has a plurality of upper hinge points arranged at equal arcs. The lower horizontal platform has the same number of lower hinge points arranged at equal arcs as the upper hinge points. Upper rotating plates are hinged to the upper hinge points, each upper rotating plate being hinged to an upper equalizing ring unit. Lower rotating plates are hinged to the lower hinge points, each lower rotating plate being hinged to a lower equalizing ring unit. The hinged structure has two rotation angle ends for both the upper and lower rotating plates, which are the unfolding end and the contraction end, respectively. When the upper and lower rotating plates are at the unfolding end, the upper and lower equalizing ring units together form a large-diameter ring structure. When the upper and lower rotating plates are at the contraction end, the upper and lower equalizing ring units move towards the center of the upper and lower horizontal platforms, respectively, causing the large-diameter ring structure to disintegrate inward.
[0012] To optimize the above technical solution, the specific measures also include:
[0013] When the upper and lower rotating plates are at the contraction end, the upper and lower equalizing ring units move towards the center of the upper and lower horizontal platforms, respectively. The upper equalizing ring units form a small-diameter ring structure, and the lower equalizing ring units form a medium-diameter ring structure with gaps between them. The diameter of the large-diameter ring structure is larger than that of the medium-diameter ring structure, which is larger than that of the small-diameter ring structure.
[0014] Both the upper and lower horizontal platforms are disc-shaped platforms. The upper hinge point is set around the center of the upper horizontal platform, and the lower hinge point is set around the center of the lower horizontal platform.
[0015] The aforementioned upper rotating plates are horizontally arranged, and each upper rotating plate has a different height. When the upper rotating plate rotates around its own upper hinge point, the upper rotating plate part of the structure can rotate to the top or bottom of the adjacent upper rotating plate.
[0016] The aforementioned lower rotating plates are horizontally arranged, and each lower rotating plate has a different height. When the lower rotating plate rotates around its own lower hinge point, the lower rotating plate part of the structure can rotate to the top or bottom of the adjacent lower rotating plate.
[0017] Each upper and lower equalizing ring unit is fixedly connected to its own connecting rod, which is hinged to the corresponding upper or lower rotating plate.
[0018] The upper and lower horizontal platforms are fixedly connected by a core tube, which passes through the core of both the upper and lower horizontal platforms.
[0019] The lower end of the aforementioned shaft tube is fixedly installed on the top of the resonant reactor.
[0020] The upper and lower equalizing ring units are located on the same horizontal plane, and the upper rotating plate, lower rotating plate, and connecting rod are all horizontally arranged.
[0021] The upper and lower equalizing ring units have the same structure, both being arc-shaped. The arc center of the upper and lower equalizing ring units is the axis of the upper and lower horizontal platforms, respectively. The upper and lower equalizing ring units are made of aluminum or aluminum alloy.
[0022] The beneficial effects of this utility model are:
[0023] 1. The equalizing ring of this invention consists of multiple ring units, which are divided into two groups and hinged to the upper and lower horizontal platforms respectively. The rotation of the upper and lower rotating plates causes the ring units to shift, allowing them to change between a large-diameter ring structure and two medium- and small-diameter ring structures. When the vehicle-mounted high-voltage test platform is in transport mode, the ring units need to be folded up to save space; in this case, the equalizing ring can be folded up into a medium- and small-diameter ring structure. When the vehicle-mounted high-voltage test platform is in operation, the ring units need to be unfolded; in this case, the equalizing ring can be unfolded into a large-diameter ring structure. This invention allows for convenient changes in the size of the equalizing ring, making it convenient for both transportation and use.
[0024] 2. The upper rotating plates of this utility model have different heights, and the lower rotating plates also have different heights. The advantage of this design is that the rotating plates in the same layer do not affect each other during rotation, preventing the ring units from jamming each other during expansion and contraction, and effectively improving the convenience of the equalizing ring expansion and contraction.

[0034] The present invention discloses a variable diameter rotating equalizing ring structure, which is installed on the top of the resonant reactor 7 of the vehicle-mounted high voltage test platform to ensure the uniform distribution of the test current in the resonant reactor 7, so as to avoid local overheating or arcing caused by uneven current.
[0035] A variable-diameter rotating equalizing ring structure includes upper and lower horizontal platforms, with rotating plates and equalizing ring units respectively arranged on each horizontal platform.
[0036] like Figure 1-3 As shown, the upper horizontal platform 1 has 6 upper hinge points 11 with equal curvature, and the lower horizontal platform 2 has 6 lower hinge points 21 with equal curvature. Correspondingly, there are 6 upper rotating plates 12, 6 lower rotating plates 22, 6 upper pressure equalizing ring units 3, and 6 lower pressure equalizing ring units 4.
[0037] Each upper rotating piece 12 is hinged to an upper hinge point 11, and each lower rotating piece 22 is hinged to a lower hinge point 21.
[0038] Each upper rotating plate 12 has a different height. When an upper rotating plate 12 rotates around its upper hinge point 11, a portion of the structure of the upper rotating plate 12 can rotate to be above or below the adjacent upper rotating plate 12. This state is from Figure 2It can be clearly seen that the green curved arm is the upper rotating plate 12. The adjacent upper rotating plates 12 fold vertically without affecting each other.
[0039] Each lower rotating piece 22 has a different height. When a lower rotating piece 22 rotates around its lower hinge point 21, part of the structure of the lower rotating piece 22 can rotate to be above or below the adjacent lower rotating piece 22. This state is from Figure 3 It can be clearly seen that the purple curved arm is the lower rotating plate 22. The adjacent lower rotating plates 22 are folded up and down without affecting each other.
[0040] A variable-diameter rotating equalizing ring structure has a contracted state and an expanded state, wherein the contracted state is as follows: Figure 1-3 As shown, the upper equalizing ring unit 3 and the lower equalizing ring unit 4 move towards the center of the upper horizontal platform 1 and the lower horizontal platform 2, respectively. The upper equalizing ring unit 3 forms a small-diameter ring structure, and the lower equalizing ring unit 4 forms a medium-diameter ring structure with gaps between the lower equalizing ring units 4. In this state, the equalizing ring structure has a small diameter, which facilitates transportation.
[0041] Expanded state as follows Figure 4 As shown, at this time, the upper equalizing ring unit 3 and the lower equalizing ring unit 4 together form a large-diameter ring structure, and the equalizing ring structure is in working state under this condition.
[0042] The equalizing ring of this invention has the following dimensions after shrinking: diameter 2200mm, ring height 500mm; and the equalizing ring has the following dimensions after unfolding: diameter 3600mm, ring height 500mm.
[0043] The shrinking and unfolding states of a variable diameter rotating equalizing ring structure are as follows: by manually pulling the upper equalizing ring unit 3 and the lower equalizing ring unit 4, the upper rotating plate 12 rotates around the upper hinge point 11, thereby causing the upper equalizing ring unit 3 to move closer to or further away from the shaft tube 6, and the lower equalizing ring unit 4 to move closer to or further away from the shaft tube 6.
