[0038] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

In addition, features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0040] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0041] like Figure 1 , Figure 2 As shown, a GIS terminal test device provided by an embodiment of the present invention includes a gas tank 100 and a test space adjustment component 200.

[0042] The gas tank 100 has a gas containing space 101 .

[0043] Specifically, the gas tank 100 is a hollow structure having a gas containing space 101, and the gas tank 100 is also provided with an air hole connected to the gas containing space 101, through which the gas containing space 101 can be evacuated and filled with SF 6 (sulfur hexafluoride) gas to simulate the insulation environment of the GIS terminal 10 in the GIS switch compartment. The air holes on the gas tank 100 can also be blocked by means of a valve or a plug to prevent gas leakage in the gas space 101. In addition, the SF 6 The air pressure value can be between 0.2Mpa and 0.6Mpa.

[0044] It should be noted that the gas tank 100 is made of conductive metal material, preferably stainless steel. The stainless steel gas tank 100 is strong, can withstand sufficient internal air pressure, and is not easy to generate electromagnetic induction to form induced current. In addition, after the stainless steel gas tank 100 is connected to the ground wire, it can ensure that the gas tank 100 is at zero potential, which can effectively ensure safety during the test.

[0045] The gas tank 100 may be arranged on a support frame 400 equipped with rollers 500, so that the entire GIS terminal test device can be moved so as to be transported to a suitable location for testing the GIS terminal 10. The rollers 500 may be universal wheels with a brake function.

[0046] Combination Figure 1 and Figure 2 The test space regulating assembly 200 is disposed in the air containing space 101 , and the test space regulating assembly 200 includes a plate 210 and two positioning plates 220 .

[0047] The two positioning plates 220 are arranged in parallel and at intervals in the gas containing space 101. Specifically in this embodiment, the two positioning plates 220 are arranged in the gas containing space 101 at intervals along the horizontal direction, and the two positioning plates 220 are fixedly connected to the inner wall of the gas tank 100.

[0048] Combination Figure 3 and Figure 4 Furthermore, each positioning plate 220 is provided with a plurality of coaxial annular grooves 220a with different inner diameters, and each positioning plate 220 is also provided with a connecting groove 220b between each two adjacent annular grooves 220a. Specifically, the plurality of annular grooves 220a on each positioning plate 220 cooperate to form concentric circles; and each connecting groove 220b connects the two annular grooves 220a on both sides thereof.

[0049] Furthermore, the annular grooves 220 a of the two positioning plates 220 are arranged opposite to each other in a one-to-one correspondence, and the communicating grooves 220 b of the two positioning plates 220 are also arranged opposite to each other in a one-to-one correspondence.

[0050] It can be understood that the number of annular grooves 220a on the two positioning plates 220 is the same, and the shapes of the two annular grooves 220a respectively arranged on the two positioning plates 220 and arranged opposite to each other are the same; the number of connecting grooves 220b on the two positioning plates 220 is the same, and the shapes of the two connecting grooves 220b respectively arranged on the two positioning plates 220 and arranged opposite to each other are also the same.

[0051] like Figure 2 As shown, the plate 210 can be bent and deformed. Specifically in this embodiment, the material of the plate 210 is aluminum. The aluminum plate 210 has the advantages of good softness and good ductility. It is preferably an aluminum material with a hardness of HB ≤ 20. Of course, in other embodiments, the plate 210 can also be made of other materials. For example, the plate 210 can be a steel plate or a copper plate that can be bent and deformed. Among them, the thickness of the plate 210 can be set to be less than 5 mm, which is easy to bend and deform.

[0052] Combination Figure 2 , Figure 3 and Figure 4 , the opposite ends of the plate 210 are respectively inserted into two annular grooves 220a arranged opposite to each other in the two positioning plates 220. It can be understood that, since the plate 210 can be bent and deformed, the plate 210 is limited by the shape of the inserted annular groove 220a, and the plate 210 will be surrounded to form a cylindrical structure. Among them, the plate 210 divides the air-containing space 101 into a first space 1011 located inside the cylindrical structure and a second space 1012 located outside the cylindrical structure. The first space 1011 and the second space 1012 are connected, and the first space 1011 is a test space for accommodating the GIS terminal 10 to be tested.

[0053] It is understandable that when SF is filled into the gas space 101 through the air hole on the gas tank 100, 6 After gas, SF 6 The gas will fill the first space 1011 and the second space 1012, and the GIS terminal 10 to be tested is set in the first space 1011 and can be 6 Surrounded, thereby simulating the insulation environment of the GIS terminal 10 in the GIS switch compartment.

[0054] Specifically, when inflating through the air holes on the gas tank 100 , the gas will first enter the second space 1012 , and then enter the first space 1011 , and finally fill the entire first space 1011 and the second space 1012 .

[0055] Among them, the material of the plate 210 is a conductive material, which can play a shielding role. Specifically in this embodiment, the plate 210, the positioning plate 220 and the gas tank 100 are all conductive materials, and the three are electrically conductive. The gas tank 100 can be connected to the grounding wire. After the gas tank 100 is grounded, the potential of the plate 210 is also zero potential, and the plate 210 serves as the shell of the GIS switch compartment.

[0056] Combination Figure 2 , Figure 3 and Figure 4 Furthermore, the plate 210 can be operably moved so that the two ends of the plate 210 pass through the connecting grooves 220b on the two positioning plates 220 and are respectively inserted into the other two relatively arranged annular grooves 220a in the two positioning plates 220; wherein, no matter which two relatively arranged annular grooves 220a in the two positioning plates 220 the two ends of the plate 210 are inserted into, the plate 210 is surrounded to form a cylindrical structure.

[0057] It is understandable that the length of the sheet 210 (referring to the length of the sheet 210 in the circumferential direction of the cylindrical structure after the sheet 210 is wound to form a cylindrical structure) satisfies: when the two ends of the sheet 210 are respectively inserted into the two annular grooves 220a with the largest inner diameters that are arranged opposite to each other in the two positioning plates 220, the sheet 210 is surrounded to form a closed cylindrical structure. In this way, no matter which two annular grooves 220a arranged opposite to each other in the two positioning plates 220 the two ends of the sheet 210 are inserted into, the sheet 210 is surrounded to form a closed cylindrical structure.

[0058] Furthermore, since the plate 210 can undergo elastic deformation, by pulling the plate 210, the two ends of the plate 210 can pass through the connecting grooves 220b on the two positioning plates 220 and enter the other two annular grooves 220a relatively arranged on the two positioning plates 220, thereby changing the inner diameter of the cylindrical structure formed by the plate 210. In this way, the plate 210 can simulate GIS switch compartments with different inner diameters to meet the test requirements of various GIS terminals 10.

[0059] It should also be noted that the inner diameter of the cylindrical structure formed by the plate 210 can be changed by changing the position of the plate 210. There is no need to repeatedly disassemble and assemble the plate 210, which is convenient to operate and can improve the test efficiency. In addition, there is no need to repeatedly replace different plates 210, which can also save costs.

[0060] Combination Figure 3 and Figure 4 In some embodiments, in each positioning plate 220: each connecting groove 220b is inclined, and the inclination direction of the connecting groove 220b is set at an angle with the radial direction of the annular groove 220a.

[0061] It can be understood that the inclination direction of the connecting groove 220b is set at an angle with the radial direction of the annular groove 220a, which can facilitate the end of the plate 210 to be pulled from one annular groove 220a to another annular groove 220a.

[0062] like Figure 2 As shown, one of the positioning plates 220 is defined as a first positioning plate 221 , and the other positioning plate 220 is defined as a second positioning plate 222 .

[0063] In some embodiments, each annular groove 220a on the first positioning plate 221 passes through both sides of the first positioning plate 221 arranged along a preset direction, wherein the preset direction is parallel to the arrangement direction of the two positioning plates 220, and each annular groove 220a on the second positioning plate 222 only passes through one side of the second positioning plate 222 close to the first positioning plate 221.

[0064] Combination Figure 2 and Figure 3 It should be noted that a joint piece 2201 is provided on the first positioning plate 221, and the joint piece 2201 is used to connect the parts on both sides of each annular groove 220a of the first positioning plate 221, so that the entire first positioning plate 221 can be formed into a whole, wherein the joint piece 2201 is located on the side of the first positioning plate 221 away from the second positioning plate 222, and the joint piece 2201 will not interfere with the movement of the end of the plate 210 along the annular groove 220a.

[0065] Combination Figure 2 , Figure 3and Figure 4 In some embodiments, each annular groove 220a on each positioning plate 220 penetrates both sides of the positioning plate 220 arranged along a preset direction; in other words, the annular groove 220a on the first positioning plate 221 penetrates both sides of the first positioning plate 221 along a preset direction, and the annular groove 220a on the second positioning plate 222 penetrates both sides of the second positioning plate 222 along a preset direction. Among them, a joint piece 2201 is provided on the side of the first positioning plate 221 away from the second positioning plate 222, and the joint piece 2201 on the first positioning plate 221 connects the parts on both sides of each annular groove 220a of the first positioning plate 221, so that the first positioning plate 221 forms a whole; a joint piece 2201 is also provided on the side of the second positioning plate 222 away from the first positioning plate 221, and the joint piece 2201 on the second positioning plate 222 connects the parts on both sides of each annular groove 220a of the second positioning plate 222, so that the second positioning plate 222 forms a whole.

[0066] Combination Figure 5 and Figure 6 Furthermore, both ends of the plate 210 arranged along the circumferential direction of the cylindrical structure are connected with transmission rods 211, and both ends of each transmission rod 211 are respectively passed through two annular grooves 220a arranged opposite to each other in the two positioning plates 220.

[0067] Specifically, the two transmission rods 211 are respectively fixed at the two ends of the plate 210 arranged along the circumferential direction of the cylindrical structure. By making the two ends of each transmission rod 211 pass through the two annular grooves 220a that are relatively arranged in the two positioning plates 220, the operator can pull the transmission rod 211 on the side of the first positioning plate 221 away from the second positioning plate 222 and / or on the side of the second positioning plate 222 away from the first positioning plate 221, so that the end of the plate 210 moves to the other annular grooves 220a, thereby improving the convenience of operation.

[0068] It should be noted that, for the joint part 2201 on the first positioning plate 221 and the second positioning plate 222, the portion of the joint part 2201 opposite to the annular groove 220a is arched, so that the portion of the joint part 2201 opposite to the annular groove 220a is further away from the annular groove 220a, thereby preventing the joint part 2201 from interfering with the transmission rod 211.

[0069] Furthermore, two ends of the transmission rod 211 are respectively releasably connected to the two positioning plates 220 .

[0070] It can be understood that when the transmission rod 211 is in a loosened state, the transmission rod 211 can be operated to move, so that the end of the plate 210 moves to the other annular groove 220a. When the transmission rod 211 is connected to the positioning plate 220, the shape of the plate 210 can be fixed to prevent the plate 210 from sliding and causing deformation of the cylindrical structure.

[0071] It should be noted that after the position of the plate 210 is fixed, the inner wall of the cylindrical structure can also be cleaned to prevent metal debris generated during the movement of the plate 210 from contaminating the GIS terminal 10 and causing creepage faults on the surface of the GIS terminal 10 during the test.

[0072] Combination Figure 6 and Figure 7 Furthermore, both ends of the transmission rod 211 are connected with connecting ears 230, and the connecting ears 230 are detachably sleeved on the outside of the transmission rod 211, and the connecting ears 230 are detachably connected to the outer side of the positioning plate 220.

[0073] It is understandable that, by means of the connecting ear 230, the transmission rod 211 can be fixed to the positioning plate 220, so that the shape of the plate 210 is fixed, and the connecting ear 230 can be removed from the positioning plate 220, so that the plate 210 can be movable.

[0074] Combination Figure 7 and Figure 8 , wherein each connecting ear 230 is provided with a mounting hole 2322, and each positioning plate 220 is provided with a plurality of assembly holes 220c. After the end of the plate 210 is inserted into different annular slots 220a, the mounting holes 2322 can be aligned with different assembly holes 220c, and then the fasteners 240 are inserted into the mounting holes 2322 and the assembly holes 220c to fix the connecting ear 230 to the plate 210. The fasteners 240 can be screws, the mounting holes 2322 are through holes, and the assembly holes 220c are threaded holes, and the fasteners 240 are inserted into the through holes and the threaded holes in sequence.

[0075] It should be noted that after the fastener 240 is removed, an auxiliary rod can be inserted into the mounting hole 2322, and the plate 210 can be pushed to move with the help of the auxiliary rod, which is more convenient.

[0076] Specifically, the connecting ear 230 includes a first connecting part 231, a second connecting part 232 and a connecting piece 233. The first connecting part 231 is provided with a first half groove 2311, and the second connecting part 232 is provided with a second half groove 2321 arranged opposite to the first half groove 2311. The first half groove 2311 and the second half groove 2321 cooperate to form a mounting hole 2322. The connecting piece 233 is used to connect the first connecting part 231 and the second connecting part 232.

[0077] Combination Figure 1 and Figure 2 In some embodiments, the gas tank 100 includes a side plate 110 and two end covers 120. The side plate 110 is arranged to form a hollow structure with openings at both ends. The two end covers 120 are respectively arranged at both ends of the hollow structure. The side plate 110 and the two end covers 120 define a gas holding space 101.

[0078] In some embodiments, the first positioning plate 221 is provided with an avoidance opening 2211, and the avoidance opening 2211 is surrounded by an annular groove 220a with the smallest inner diameter on the first positioning plate 221; one of the end covers 120 is defined as the first end cover 121, and the other end cover 120 is defined as the second end cover 122; the first end cover 121 is located on the side of the first positioning plate 221 away from the second positioning plate 222, and the first end cover 121 is provided with an inlet 1211 arranged opposite to the avoidance opening 2211; the second end cover 122 is located on the side of the second positioning plate 222 away from the first positioning plate 221, and the second end cover 122 seals the opening of the hollow structure.

[0079] Combination Figure 1 and Figure 2 It can be understood that the GIS terminal 10 connected with the cable 20 can be inserted into the first space 1011 through the loading port 1211 and the avoidance port 2211, and after the GIS terminal 10 is placed in place, the GIS terminal 10 seals the loading port 1211, so that the entire air-containing space 101 can be sealed.

[0080] The GIS terminal 10 can be fixed to the first end cover 121 by a flange.

[0081] It should be noted that the first space 1011 can be connected to the second space 1012 through a gap between the hole wall of the avoidance opening 2211 and the outer wall of the GIS terminal 10 .

[0082] Furthermore, the second positioning plate 222 is provided with a communication port 2221 , which is surrounded by the annular groove 220 a with the smallest inner diameter on the second positioning plate 222 , and the communication port 2221 is communicated with the second space 1012 .

[0083] It can be understood that the first space 1011 and the second space 1012 can be connected through the connecting port 2221 and the annular groove 220a on the second positioning plate 222. Of course, the second positioning plate 222 can also be provided with a ventilation ring surrounding the annular groove 220a with the largest inner diameter on the second positioning plate 222, and the first space 1011 and the second space 1012 can also be connected through the connecting port 2221 and the ventilation ring on the second positioning plate 222; in addition, the first space 1011 and the second space 1012 can also be connected through the gap between the hole wall of the avoidance port 2211 and the outer wall of the GIS terminal 10, and the annular groove 220a on the first positioning plate 221. Of course, the first positioning plate 221 can also be provided with a ventilation ring surrounding the annular groove 220a with the largest inner diameter on the first positioning plate 221, and the first space 1011 and the second space 1012 can also be connected through the gap between the hole wall of the avoidance port 2211 and the outer wall of the GIS terminal 10, and the ventilation ring on the first positioning plate 221.

[0084] The ventilation ring may be a non-closed ring structure.

[0085] It should be noted that the side plate 110 is provided with air holes. When inflating through the air holes on the side plate 110 , the gas will first enter the second space 1012 and then enter the first space 1011 , and finally fill the entire first space 1011 and the second space 1012 .

[0086] It should be noted that the two end covers 120 are detachably connected to the side plate 110 . For example, the two end covers 120 are fixed to the side plate 110 by bolts. After the end covers 120 are removed, the position of the plate 220 can be easily adjusted.

[0087] It should be noted that a shielding ball 300 may be provided at the end of the GIS terminal 10 to prevent tip discharge.

[0088] In the GIS terminal test device of the present invention, since the plate 210 can be elastically deformed, by pulling the plate 210, the two ends of the plate 210 can pass through the connecting grooves 220b on the two positioning plates 220 and enter the other two annular grooves 220a arranged oppositely on the two positioning plates 220, so that the inner diameter of the cylindrical structure formed by the plate 210 changes. In this way, the plate 210 can simulate GIS switch compartments with different inner diameters and meet the test requirements of various GIS terminals 10. Among them, the test voltage of the GIS terminal test device of the present invention can reach up to 750KV.
