Technical Field
[0001] The utility model relates to the technical field of lightning rod testers, in particular to a lightning arrester characteristic tester. Background Art
[0002] A lightning arrester is an electrical device used to protect electrical equipment from high transient overvoltage hazards and limit the follow-on time and often the follow-on amplitude. It is used to protect the insulation of AC power transmission and transformation equipment from lightning overvoltage and operating overvoltage damage.
[0003] When using traditional lightning rod detection equipment, the lightning rod tester is generally composed of a main unit, a detection head, and a tool box. When using the traditional tester, the main unit needs to be held in hand or placed on the ground. Holding the main unit for a long time for testing will be very physically demanding. Placing the tester on the ground does not allow for good observation of the main unit, which makes the equipment very inconvenient when used in the field. Moreover, when testing the lightning rod, live operation is required. In order to ensure safety, a longer connecting wire is required. The connecting wire of the traditional equipment is directly placed inside the tool box, causing the interior of the tool box to be relatively messy. Utility Model Content

[0007] As a preferred technical solution of the utility model: there are two No. 1 movable plates, and the two No. 1 movable plates are respectively slidably connected to both sides of the top of the box cover.
[0008] As a preferred technical solution of the utility model: the outer wall of the screw rod passes through the outer wall of the box cover, and the outer wall of the screw rod is threadedly connected to the inner wall of the moving rod.
[0009] As a preferred technical solution of the utility model: the outer wall of the winding wheel passes through the outer wall of the tool box and is connected to the outer wall of the reel rod, and the diameter of the outer wall of the winding wheel is smaller than the depth of the inner cavity of the tool box.
[0010] As a preferred technical solution of the utility model: the shape and size of the inner cavity of the buffer plate matches the shape and size of the outer wall of the main machine, and the buffer plate is made of polyurethane foam material.
[0011] Compared with the prior art, the utility model has the following beneficial effects:
[0012] 1. The arrester characteristic tester has a No. 1 movable plate and a No. 2 movable plate arranged on the outer wall of the box cover. When the operating table needs to be raised or lowered, it is only necessary to rotate the screw rod so that the screw rod drives the movable rod to move, thereby changing the distance between the No. 1 movable plate and the No. 2 movable plate under the action of the movable rod, and changing the height of the operating table. The main unit can be operated on the operating table, avoiding holding the main unit or placing the main unit on the ground, and operating the main unit more conveniently.
[0013] 2. The lightning arrester characteristic tester uses a winding wheel and a reeling rod arranged inside a tool box. By winding one end of the connecting wire around the outer wall of the winding wheel, the winding wheel is driven to rotate by rotating the reel, so as to better reel in the connecting wire and avoid the connecting wire being placed in a messy manner inside the tool box, so that the space inside the tool box can be better utilized.

[0021] See also Figure 1-5 A lightning arrester characteristic tester comprises a toolbox 1, the outer wall of the toolbox 1 is rotatably connected with a box cover 2, a sliding plate 3 is installed on the top of the box cover 2, a movable plate 4 is slidably connected to the inner cavity of the sliding plate 3, a movable plate 5 is rotatably connected to the outer wall of the box cover 2, an operating table 6 is rotatably connected to the outer wall of the movable plate 4, a movable rod 7 is fixedly installed on the outer wall of the movable plate 4, a screw 8 is rotatably connected to the outer wall of the box cover 2, a device bin 9 is fixedly installed in the inner cavity of the toolbox 1, a main machine 10 is installed in the inner cavity of the toolbox 1, a winding wheel 11 is rotatably connected to the inner cavity of the toolbox 1, a winding rod 12 is fixedly installed on the outer edge of the winding wheel 11, and a buffer plate 13 is fixedly installed on the bottom of the inner cavity of the toolbox 1.
[0022] By setting the winding wheel 11 in the inner cavity of the tool box 1, since the main unit 10 needs to be powered for testing during use, in order to ensure safety, the connecting line of the equipment will often be relatively long. The winding rod 12 can be rotated so that the winding rod 12 drives the rotation of the winding wheel 11, thereby winding the connecting line under the action of the winding wheel 11.
[0023] In a preferred embodiment: the outer wall of the first movable plate 4 away from the sliding plate 3 is rotatably connected to the outer wall of the operating table 6, and the second movable plate 5 is slidably connected to the outer wall of the operating table 6 at one end away from the box cover 2.
[0024] By slidingly and rotatably connecting the two ends of the No. 1 movable plate 4 to the outer walls of the box cover 2 and the operating table 6 respectively, the entire operating table 6 can be raised and lowered with the cooperation of the No. 1 movable plate 4 and the No. 2 movable plate 5. Driven by the moving rod 7, the No. 1 movable plate 4 can slide along the inner wall of the sliding plate 3, thereby changing the angle between the No. 1 movable plate 4 and the No. 2 movable plate 5, thereby adjusting the height of the operating table 6.
[0025] In a preferred embodiment, there are two No. 1 movable plates 4 , and the two No. 1 movable plates 4 are slidably connected to both sides of the top of the box cover 2 .
[0026] By arranging a No. 1 movable plate 4 on both sides of the top of the No. 1 movable plate 4, the movable rod 7 can be better pulled to move under the action of the screw rod 8, thereby driving the movement of the No. 1 movable plate 4 on both sides under the action of the movable rod 7, and the height of the operating table 6 can be adjusted under the action of the No. 1 movable plate 4 and the No. 2 movable plate 5.
[0027] In a preferred embodiment, the outer wall of the screw rod 8 passes through the outer wall of the box cover 2 , and the outer wall of the screw rod 8 is threadedly connected to the inner wall of the moving rod 7 .
[0028] By rotating the connected screw 8 on the outer wall of the box cover 2, the moving rod 7 can be moved back and forth under the action of the screw 8. During the movement of the moving rod 7, the position of the No. 1 moving plate 4 on both sides can be pulled to move, thereby adjusting the height of the operating table 6 during the movement of the No. 1 moving plate 4.
[0029] In a preferred embodiment, the outer wall of the winding wheel 11 passes through the outer wall of the tool box 1 and is connected to the outer wall of the winding rod 12 , and the diameter of the outer wall of the winding wheel 11 is smaller than the depth of the inner cavity of the tool box 1 .
[0030] By setting the winding wheel 11 in the inner cavity of the tool box 1, when the connecting line needs to be reeled in after the use of the main unit 10, it is only necessary to initially wind the connecting line around the outer wall of the winding wheel 11, and then rotate the reeling rod 12 so that the winding wheel 11 can reel in the connecting line during the rotation process, which is very convenient and quick.
[0031] In a preferred embodiment, the shape and size of the inner cavity of the buffer plate 13 matches the shape and size of the outer wall of the host 10 , and the buffer plate 13 is made of polyurethane foam material.
[0032] By setting a buffer plate 13 at the bottom of the inner cavity of the tool box 1, and the buffer plate 13 made of polyurethane foam material can better protect the host 10. After using the host 10, the host 10 is directly placed in the inner cavity of the buffer plate 13, and the host 10 can be fixed under the action of the buffer plate 13 and play a protective role.
[0033] Working principle: during the use of the above-mentioned equipment, when the host 10 is needed to detect the lightning arrester, the host 10 is taken out from the inner cavity of the tool box 1, and then the connecting line on the outer wall of the winding wheel 11 is pulled to connect the connecting line with the host 10, and then the screw rod 8 is rotated so that the screw rod 8 drives the movement of the moving rod 7 during the rotation. At this time, the moving rod 7 can drive the movement of the No. 1 moving plate 4 during the movement. The No. 1 moving plate 4 can change the angle with the No. 2 moving plate 5 during the movement, thereby raising the height of the operating table 6, and the host 10 can be placed on the top of the operating table 6 for operation, which is very convenient and enables operation to be performed on the top of the operating table 6. After the detection is completed, the screw rod 8 is rotated to make the screw 8 pull the moving rod 7 again to move, thereby lowering the height of the operating table 6 and reducing the space occupied by the tool box 1, making the equipment more convenient when in use.
[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
