Description

Technical Field

[0001] This utility model relates to the field of transformers, and in particular to a device for testing the processed transformer core. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current voltage. It mainly consists of an iron core and coils. The iron core vibrates under the influence of changes in excitation current through magnetostriction. By detecting the amplitude and frequency of this vibration, it's possible to determine if the iron core is damaged or loose (the iron core is composed of stacked silicon steel sheets). Currently, existing vibration detection devices typically fix the iron core in clamps. However, because transformer cores on the market vary in shape, the detection range of these devices is limited, preventing them from detecting different locations on the iron core.

[0020] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0021] like Figure 1 and 2 As shown, this embodiment discloses a transformer core testing device, including a platform 1 for placing the core 10, a plurality of adjusting brackets 6 on the platform 1, and a vibration sensor 7 on the adjusting brackets 6. The adjusting brackets 6 can adjust the position of the vibration sensor 7.

[0022] The adjusting bracket 6 includes a base 601, which is mounted on the platform 1. A vertical support arm 602 is fixed on the base 601. The vertical support arm 602 is connected to a horizontal support arm 604 via a clamping seat 603. A pressure plate 605 is provided at the front end of the horizontal support arm 604, and a sensor support 606 is provided on the pressure plate 605. The vibration sensor 7 is mounted on the sensor support 606. The pressure plate 605 has a certain degree of elasticity, which allows the sensor support 606 to abut against the iron core 10.

[0023] During testing, a test current is applied to the windings on the iron core 10 to cause the iron core 10 to vibrate. The vibration sensor 7 is connected to the processor via a data cable and feeds back the vibration signal to the processor. The processor can be a computer, terminal, or tablet computer, etc.

[0024] In this embodiment, the sensor support 606 is L-shaped. The bottom surface of the horizontal part of the sensor support 606 is in contact with the iron core 10. The vibration sensor 7 is installed on the top surface of the horizontal part of the sensor support 606. The vertical part of the sensor support 606 is connected to the pressure plate 605.

[0025] In this embodiment, the platform 1 is set on the track trolley 2, the track trolley 2 moves along the track 4 below, and a protective cover 3 is provided at one end of the track trolley 2. The protective cover 3 has an inlet 5 on the side facing the track 4. When testing is required, the track trolley 2 can be pushed into the protective cover 3.

[0026] like Figure 3 As shown, the clamping base 603 includes a clamping block 603-1, and each end of the clamping block 603-1 is provided with a jaw assembly 603-2. The two jaw assemblies 603-2 are respectively clamped and engaged with the vertical support arm 602 and the horizontal support arm 604. The jaw assembly 603-2 includes two jaws 603-2-1, and a clamping hole 603-2-2 is provided between the two jaws 603-2-1 to engage with the vertical support arm 602 or the horizontal support arm 604. In this embodiment, the axes of the two clamping holes 603-2-2 are arranged vertically. Two grippers 603-2-1 are connected by a hand-tightening bolt 603-2-3. One gripper 603-2-1 has a through hole, and the other gripper 603-2-1 has a threaded hole. The hand-tightening bolt 603-2-3 passes through the through hole and connects to the threaded hole on the other gripper 603-2-1. Tightening the hand-tightening bolt 603-2-3 can bring the two grippers 603-2-1 closer together and thus clamp the middle vertical support arm 602 or horizontal support arm 604.

[0027] In this embodiment, anti-slip textures are provided on the outer walls of both the vertical support arm 602 and the horizontal support arm 604.

[0028] In this embodiment, the platform 1 is provided with a plurality of mounting holes 8, and the iron core clamp 10 and the base 601 are all installed in the mounting holes 8 by bolts.

[0029] In this embodiment, a viewing window 9 is provided on one side wall of the protective cover 3 to facilitate observation by personnel from the outside of the protective cover 3.

[0030] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
