TECHNICAL FIELD
[0001] The utility model belongs to the technical field of high pressure test platform, especially relate to a chute formula foldable grading ring structure for high pressure test platform. BACKGROUND
[0002] High pressure test platform is usually used for testing and verifying the performance and safety of various devices and materials under high pressure environment. It is widely used in aerospace, energy, chemical industry, material science and other fields.
[0003] In order to improve the high pressure test efficiency of large equipment, part of the high pressure test platform is installed on the transport vehicle to form the vehicle-mounted high pressure test platform. However, with the development of society, the size of equipment, experimental requirements and other gradually rise, especially in recent years, with the gradual construction and commissioning of ultrahigh voltage grade (AC 750kV and above) GIS type equipment (including GIL), the test workload is steadily increasing, and the test difficulty is gradually increasing. The size of the vehicle-mounted high pressure test platform is also gradually increasing. Correspondingly, the grading ring on the vehicle-mounted high pressure test platform, which is used to improve the stability of the power system, is also larger. The grading ring is used to reduce the sharpness of the electric field at some points, making the electric field more smooth, thereby avoiding the phenomenon of local high electric field. This makes the vehicle-mounted high pressure test platform pass through some height limit bridges, and the height of the grading ring is higher than the height limit, which causes great inconvenience to the passage of the vehicle-mounted high pressure test platform.

When the grading ring is not used, it is folded after deflation. However, since the grading ring needs to have good conductivity, the grading ring is generally made of aluminum or copper or an alloy of the two. The grading ring cannot be inflated and deflated like a rubber ring, and frequent folding can cause metal material fatigue and increase the failure rate of the grading ring.

[0035] The high-pressure test platform sliding groove type foldable grading ring structure of the utility model mainly comprises mounting platform 1, sliding frame 2, grading ring structure 3 and resonant reactor 4. Among them,
[0036] The mounting platform 1 is a two-layer horizontal platform, one high and one low, the high one is the upper platform 13, and the low one is the lower platform 14, the upper platform 13 and the lower platform 14 are arranged in parallel, and the upper platform 13 and the lower platform 14 are fixedly connected with the upper end of the resonant reactor 4 through screws.
[0037] Two horizontal rails 11 are arranged on the upper platform 13, two "I" shaped units 32 are respectively slidably installed on the two groups of horizontal rails 11,
[0038] Two vertical rails 12 are arranged on the upper platform 13, two "C" shaped units 33 are respectively slidably installed on the two groups of vertical rails 12,
[0039] Each group of horizontal rails 11 and each group of vertical rails 12 comprise two parallel rail units, and a sliding block 15 is slidably installed on each rail unit. Each "I" shaped unit 32 and C" shaped unit 33 are provided with a sliding frame 2, one end of the sliding frame 2 is fixedly connected with the corresponding "I" shaped unit 32 and C" shaped unit 33, and the other end is fixedly connected with the sliding block 15.
[0040] FromFigures 2-3 As can be seen from 6-8, among the four ring units 31, two "C"-shaped units 33 are arranged opposite each other, and two "I"-shaped units 32 are arranged opposite each other.
[0041] The high-pressure test platform of this utility model uses a sliding groove type foldable equalizing ring structure with two states: an unfolded state and a folded state. The unfolded state is as follows: Figures 1-5 As shown, the folded state is as follows Figures 6-8 As shown. In the unfolded state, the two ends of the "C"-shaped unit 33 are respectively connected to one end of the two "I"-shaped units 32, forming a square equalizing ring structure 3. In the folded state, the two "I"-shaped units 32 first slide inward, moving to the inside of the "C"-shaped unit 33, and then the two "C"-shaped units 33 slide inward again, forming a square equalizing ring structure 3. Figures 6-8 As shown, in this state, the height of the equalizing ring structure 3 is significantly reduced (the side containing the "I"-shaped unit 32 is in the vertical direction, and the side containing the "C"-shaped unit 33 is in the horizontal direction). When the high-voltage test platform is transported on a transport vehicle, the resonant reactor 4 is in a lying-down state, and the equalizing ring structure 3 is in a folded state. The reduced height of the equalizing ring structure 3 allows it to pass smoothly over height-restricted road bridges, facilitating transportation. When the high-voltage test platform is transported to the target location for high-voltage insulation testing, the resonant reactor 4 is erected. At this time, simply pulling out the "C"-shaped unit 33 and then the "I"-shaped unit 32 will unfold the equalizing ring structure 3, allowing it to function normally. It is extremely convenient to use.
[0042] 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. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should be considered within its protection scope.
