Description

Technical Field

[0001] This utility model relates to the field of switchgear technology, and in particular to a fixing mechanism and a voltage testing trolley. Background Technology

[0002] In recent years, medium-voltage switchgear has been widely used in power systems, especially 10kV systems, due to its compact structure, good enclosure, and safety and reliability. During regular maintenance and testing of switchgear and handcart switches, after a power outage, it is necessary to verify the voltage at the grounding switch to confirm that there is no voltage before the grounding wire is installed on the electrical equipment, thus preventing serious accidents caused by improper operation such as connecting grounding wires while the equipment is energized.

[0003] When performing insulation testing inside a 10kV armored switchgear, the voltage testing trolley needs to be pushed into the switchgear, the baffle opened, and the operator holding the test leads leaning into the switchgear to test the insulation. Because there is no fixed position for the test leads inside the switchgear, the operator needs to hold the test leads against the position of the insulation being tested while testing. Since the operator needs to lean into the switchgear throughout the entire process, there is a risk of electric shock to the operator. Utility Model Content

Obviously, the drawings described below are only some embodiments of this utility model. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort. Among them: Figure 1 This is a diagram showing the overall structure of the present invention.

[0019] Figure 2 This is a diagram illustrating the adjustment component in this utility model.

[0020] Figure 3 This is a diagram illustrating the fixing component in this utility model. Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1 Reference Figure 1 This is the first embodiment of the present utility model. This embodiment provides a fixing mechanism, including a bearing component 1. The bearing component 1 includes a voltage testing trolley body 11 and a contact 131 disposed above the voltage testing trolley body 11. After the fixing contact 131 is installed, it makes contact with the detection point of the switch cabinet through the contact 131. After the contact is completed, it determines whether the switch cabinet has current through the contact 131.

[0025] The fixing component 3 includes a fixing collar 31 located at one end of the contact 131. The width of the fixing collar 31 is greater than that of the connecting rod 13, so it can support connecting rods 13 of different specifications and fix the connecting rods 13 of different specifications.

[0026] The supporting component 1 also includes a supporting groove 111 opened inside the body 11 of the voltage testing trolley. One end of the voltage testing trolley body 11 is provided with a baffle. A caster wheel 12 is provided below the voltage testing trolley body 11. A connecting rod 13 is provided inside the fixing collar 31. The connecting rod 13 is sleeved on the outside of the contact 131. A baffle is installed at one end of the voltage testing trolley body 11. The baffle is made of insulating material and is used to protect the operator. A push handle is installed at one end of the baffle to facilitate the operator's movement.

[0027] Usage process: First, move the trolley in its stored state to the switch cabinet to be tested using the casters 12. Then, adjust the adjustment component 2, the voltage testing component 4, the connecting rod 13 and the contact 131 fixed on the fixing collar 31. Finally, hang the probes of the megohmmeter on the adjustment component 2 to test the switch cabinet.

[0028] Example 2 Reference Figures 1-3 This is the second embodiment of the present invention. Unlike the previous embodiment, it also includes a convex plate disposed above the fixing collar 31. The inner side of the convex plate is provided with a rotating shaft 311, the outer side of the rotating shaft 311 is provided with a rotating rod 32, and the outer side of the rotating rod 32 is provided with a toggle plate 321.

[0029] The rotating shaft 311 is located at the eccentric position of the rotating rod 32. By positioning the rotating rod 32 away from the center, the position of the rotating rod 32 will change when the actuating plate 321 drives the rotating rod 32 to rotate.

[0030] The fixed collar 31 has a pressing plate 33 inside, a top plate 331 above the pressing plate 33, and a top rod 332 above the pressing plate 33. The upper end of the top plate 331 is curved. When the rotating rod 32 presses the top plate 331 and the top rod 332, the top plate 331 and the top rod 332 will drive the pressing plate 33 to move down, and then the pressing plate 33 will press and fix the connecting rod 13.

[0031] Usage process: First, install the contact 131 and the connecting rod 13. Then, place the connecting rod 13 into the fixing collar 31. Through the actuating plate 321, the actuating plate 321 drives the rotating rod 32 to rotate. Because the actuating plate 321 is connected to the eccentric part of the rotating rod 32, the rotating rod 32 swings downward and presses the top plate 331 and the top rod 332. The top plate 331 and the top rod 332 press the pressing plate 33, and then the pressing plate 33 presses the connecting rod 13 to fix it. Then, the switch cabinet is tested.

[0032] Example 3 Reference Figures 1-3This is the third embodiment of the present invention, which further provides a voltage testing cart. It includes an adjustment assembly 2, comprising a fixed plate 21 disposed at the top of the voltage testing cart body 11, a first adjustment plate 22 disposed outside the fixed plate 21, and a second adjustment plate 221 disposed above the first adjustment plate 22; and a voltage testing assembly 4, comprising a first support rod 41 disposed at one end of the second adjustment plate 221. The adjustment assembly 2 is arranged in a horizontal array above the support groove 111. The adjustment assembly 2 also includes a first adjustment shaft 211 located on the outside of the fixed plate 21. The first adjustment plate 22 rotates on the outside of the first adjustment shaft 211. The second adjustment plate 221 has a second adjustment shaft 2211 located on the inside. The second adjustment shaft 2211 has a mounting plate 23 located on the outside. The mounting plate 23 has a mounting hole 231 on its inside. The first adjustment plate 22 is rotated and mounted on the outside of the first adjustment shaft 211 via the fixed plate 21, thereby allowing the first adjustment plate 22 to be completely housed in the bearing groove 111. This reduces the size of the voltage testing trolley and makes it easier for the voltage testing trolley to enter the room to test the switch cabinet.

[0033] The electrical measurement component 4 also includes a rotating plate located at one end of the first support rod 41. The rotating plate is located outside the second adjusting shaft 2211, and a second support rod 411 is provided at one end of the first support rod 41.

[0034] Usage: When insulation needs to be tested, adjust the first adjusting plate 22, and the fixed plate 21 is rotatably connected to the first adjusting plate 22 to raise the insulating rod vertically and keep it parallel to the fixed plate 21. Then adjust the first support rod 41, and the first support rod 41 is rotatably connected to the second adjusting plate 221 to raise the first support rod 41 horizontally and keep it parallel to the voltage testing trolley body 11. Then fix the connecting rod 13 and the contact 131 through the fixing component 3. Finally, hang the test probe of the megohmmeter on the mounting hole 231 opened on the mounting plate 23 to perform the insulation test.
