Technical Field

[0001] This utility model relates to the field of testing equipment technology, specifically to a partial discharge testing device for insulating components. Background Technology

[0002] The partial discharge testing device for insulation components is specifically designed for partial discharge testing of switchgear insulation components. It is used to securely install insulation components that can withstand various testing conditions. However, because switchgear insulation components such as insulators, bushings, and contact boxes vary in structure and dimensions across different manufacturers and voltage levels, existing testing devices struggle to flexibly adapt to multiple types of insulation components, resulting in poor practicality. Furthermore, current devices cannot automatically adjust height and tilt angle, requiring manual adjustment, which is not only time-consuming and labor-intensive but also reduces testing efficiency. Utility Model Content

[0003] This invention provides a partial discharge testing device for insulating components to solve the above-mentioned problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A partial discharge test device for insulating components includes a fixed base, an adjustment component mounted on the base surface of the fixed base, a support frame mounted on one end of the adjustment component, a U-shaped groove formed on the outer wall of the support frame, a threaded hole formed on the inner wall of the U-shaped groove, and an adjustable fixing rod mounted on the inner wall of the U-shaped groove.

[0006] The adjustable fixing rod includes a circular slide rod, which is installed at one end of the support frame. The circular slide rod has a fixing hole on its opposite outer wall. The circular slide rod is rotatably connected to a movable lifting lug on its opposite outer wall. The movable lifting lug has a threaded connection hole on its outer wall. A locking bolt is threaded onto the inner wall of the threaded connection hole.

[0007] As a preferred embodiment of this utility model, one end of the locking bolt is located on the outer wall of the circular slide rod, and an installation hole is provided on the outer wall of the movable lug.

[0008] As a preferred embodiment of this utility model, a contact box is installed on the inner wall of the mounting hole, and a protective pad is provided between the movable lug and the circular slide rod and on the side of the locking bolt.

[0009] As a preferred embodiment of this utility model, the adjustment component includes an electronically controlled cylinder, a controller, a tilt sensor, and a height sensor.

[0010] As a preferred embodiment of this utility model, the electrically controlled cylinder is provided in multiple sets and is located on the base surface of the fixed base. One end of the electrically controlled cylinder is equipped with a rotating component, and one end of the rotating component is connected to a support frame.

[0011] As a preferred embodiment of this utility model, the controller is installed on the side wall of the support frame, the tilt sensor is installed on the outer wall of the support frame, and the height sensor is installed on the outer wall of the support frame.

[0012] As a preferred embodiment of this utility model, the controller is electrically connected to an electric cylinder, an inclination sensor, and a height sensor via wires, and the fixing hole is located directly above the threaded hole.

[0013] This utility model uses a support frame as the main body of the device, which provides stable support and ensures continuous grounding. The U-shaped groove and threaded hole design on it, together with the adjustable fixing rod, enables the rapid installation and angle adjustment of test samples. The combination of movable lifting lugs and locking bolts allows for convenient position adjustment and fixation of both small and large samples. This design not only improves the testing efficiency but also enhances the adaptability of the device to insulating parts of different sizes, significantly improving its practicality.

[0014] The device of this utility model is equipped with an adjustment component that can adjust the height and tilt angle of the device. One end of the electric cylinder applies a thrust to the support frame through a rotating component. Since there are multiple sets of electric cylinders, the electric cylinders on both sides of the support frame are raised and lowered to a suitable height. When there is a height difference between the two sets of electric cylinders, the height and tilt angle of the support frame meet the requirements. At the same time, the tilt sensor and the height sensor generate electrical signals that are transmitted to the controller through wires. When the controller adjusts the value to the reference parameter, the controller controls the electric cylinder to stop rotating, and the device can automatically adjust the height.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0022] Example: Please refer to Figure 1-5 The partial discharge test device for an insulating component shown includes a fixed base 1, an adjustment component 2 mounted on the base surface of the fixed base 1, a support frame 3 mounted on one end of the adjustment component 2, a U-shaped groove 4 opened on the outer wall of the support frame 3, a threaded hole 5 opened on the inner wall of the U-shaped groove 4, and an adjustable fixing rod 6 mounted on the inner wall of the U-shaped groove 4.

[0023] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 4 The adjustable fixing rod 6 includes a circular slide rod 61, which is installed at one end of the support frame 3. A fixing hole 62 is provided on the opposite outer wall of the circular slide rod 61. A movable lifting lug 63 is rotatably connected to the opposite outer wall of the circular slide rod 61. A threaded connection hole 64 is provided on the outer wall of the movable lifting lug 63. A locking bolt 65 is threadedly connected to the inner wall of the threaded connection hole 64. One end of the locking bolt 65 is located on the outer wall of the circular slide rod 61. An installation hole 66 is provided on the outer wall of the movable lifting lug 63. A contact box 67 is installed on the inner wall of the installation hole 66. A protective pad is provided between the movable lifting lug 63 and the circular slide rod 61 and on the side of the locking bolt 65.

[0024] In this embodiment, specific references Figure 1 , Figure 2 , Figure 3 and Figure 5The adjustment assembly 2 includes an electric cylinder 201, a controller 202, an inclination sensor 203, and a height sensor 204. Multiple sets of electric cylinders 201 are provided and are located on the base surface of the fixed base 1. A rotating part 205 is installed at one end of the electric cylinder 201, and a support frame 3 is connected to one end of the rotating part 205. The controller 202 is installed on the side wall of the support frame 3, the inclination sensor 203 is installed on the outer wall of the support frame 3, and the height sensor 204 is installed on the outer wall of the support frame 3.

[0025] Based on the above structural features and connection relationships, the support frame 3 is made of metal. The I-shaped foot structure is simple and stable. One end of the foot has a grounding point for grounding wire connection. Columns are connected to the middle of both sides of the foot of the support frame 3. The top of the column of the support frame 3 has a U-shaped groove 4, and the bottom of the U-shaped groove 4 has a threaded hole 5 for bolt connection with the fixing hole 62 of the adjustable fixing rod 6. The support frame 3 is both the main support of the device and ensures continuous grounding of the test sample.

[0026] The controller 202 is electrically connected to the electric cylinder 201, tilt sensor 203 and height sensor 204 via wires, which powers the device and causes the controller 202 to control the electric cylinder 201, tilt sensor 203 and height sensor 204 to operate. The fixing hole 62 is located directly above the threaded hole 5.

[0027] When the insulation partial discharge test device of this scheme is working, the support frame 3 is connected to the columns at the center of both sides of the foot. The top of the column of the support frame 3 is opened with a U-shaped groove 4, and the bottom of the U-shaped groove 4 is opened with a threaded hole 5 for bolt connection with the fixing hole 62 of the adjustable fixing rod 6. The support frame 3 is not only the main support of the device, but also maintains the grounding continuity of the test sample.

[0028] The circular slide rod 61 has fixing holes 62 at both ends, which mate with the threaded holes 5 at the bottom of the U-shaped groove 4 of the support frame 3. The two can be connected with bolts. Two movable lifting lugs 63 are fitted on the circular slide rod 61. The movable lifting lugs 63 can move freely at any position on the circular slide rod 61. Sample mounting holes 66 and locking bolts 65 are welded on the movable lifting lugs 63. The sample mounting holes 66 can be connected to the test sample with bolts. The locking bolts 65 are used for positioning and fixing the test sample after installation. A protective pad is placed in the contact gap between the locking bolts 65 and the circular slide rod 61. When the locking bolts 65 perform the locking action, the locking bolts 65 abut against the protective pads. The protective pads are pressed and fit against the circular slide rod 61, which has the function of stopping movement and protecting the circular slide rod 61 from damage.

[0029] With the above structure, the test sample can be installed in two ways. For small samples, they can be picked up directly, the position of the movable lifting lug 63 can be adjusted, the sample can be connected to the mounting hole 66 with bolts, the position and angle can be adjusted, and finally the locking bolt 65 can be tightened. For large samples, the adjustable fixing rod 6 can be removed first, the sample can be connected to the mounting hole 66, and then the adjustable fixing rod 6 can be lifted and inserted into the U-shaped groove 4 of the support frame 3. Finally, the position and angle can be adjusted and the position can be locked. This solves the problem that the existing test device is difficult to flexibly adapt to various types of insulating parts due to the different structural dimensions of different manufacturers and voltage levels, resulting in poor practicality.

[0030] By inputting parameters into the controller 202, the controller 202 controls the operation of the electric cylinder 201. This causes one end of the electric cylinder 201 to apply a thrust to the support frame 3 via the rotating component 205. Since there are multiple sets of electric cylinders 201, the electric cylinders 201 on both sides of the support frame 3 are raised and lowered to appropriate heights. The height difference between the two sets of electric cylinders 201 ensures that the height and tilt angle of the support frame 3 meet the requirements. At the same time, the tilt sensor 203 and the height sensor 204 generate electrical signals that are transmitted to the controller 202 through wires. When the controller 202 adjusts the values ​​to the reference parameters, it stops the electric cylinder 201. The device can automatically adjust the height, thus solving the problem that the current device cannot automatically adjust the height and tilt angle, requiring manual adjustment, which is not only time-consuming and labor-intensive but also reduces the efficiency of the test.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
