[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides an electrical film breakdown test device, such as Figure 1-Figure 4 As shown, it includes a cabinet 1, a partition is installed in the middle of the interior of the cabinet 1, a support seat 4 is installed on the upper part of the partition, a clamping assembly 3 is installed on the top of the support seat 4 for clamping and fixing the electrical membrane, an electrical membrane roll 5 is installed on the top of the clamping assembly 3, telescopic assemblies 2 are installed on both sides of the top of the electrical membrane roll 5, and an experimental equipment 13 is installed under the partition, and the outer side of the electrical membrane roll 5 is electrically connected to the experimental equipment 13 through wiring for conducting an electrical membrane breakdown test.

[0022] In this embodiment, an upper cabinet door 11 is installed on the upper part of the outer wall of the cabinet 1, a lower cabinet door 12 is installed on the lower part of the outer wall of the cabinet 1, and a glass window 111 is installed on the outer wall of the upper cabinet door 11 for observing the test process.

[0023] Specifically, the clamping assembly 3 includes a shell 31, and screw rods 32 are symmetrically arranged on both sides of the interior of the shell 31, and a screw slider 321 is installed on the screw rod 32, and a rotating shaft 33 is installed at the lower middle part of the shell 31. The bottom end of the rotating shaft 33 is driven to rotate by a driving motor 331, and an active bevel gear 332 is installed at the top of the rotating shaft 33. A driven bevel gear 322 is installed at the end of the screw rod 32, and both sides of the active bevel gear 332 are meshed with the driven bevel gear 322. The top of the screw slider 321 is connected and fixed to the bottom of the pressure plate 34, and the screw slider 321 is driven to move by the rotation of the screw rod 32, and then the pressure plate 34 is moved, thereby achieving clamping and fixing from the inner side of the electrical film roll 5.

[0024] Specifically, one end of the screw rod 32 away from the driven bevel gear 322 is rotatably connected to the inner wall of the housing 31 through a bearing, so that the screw rod 32 can rotate flexibly.

[0025] Specifically, the outer wall of the pressing plate 34 is in contact with the inner wall of the top inner cavity of the electrical film roll 5 to ensure that the electrical film roll 5 is stably clamped.

[0026] Furthermore, the telescopic assembly 2 includes a telescopic cylinder 21, the output shaft of which is equipped with a piston rod 22, and the outer end of the piston rod 22 is equipped with an insulating pad 23. The piston rod 22 is extended by the telescopic cylinder 21, and the wiring is crimped onto the outer wall of the electrical film roll 5 through the insulating pad 23 to ensure that the wiring is stable and not loose.

[0027] Furthermore, a slide groove 311 is provided on the top of the housing 31 , and the screw slider 321 is slidably matched with the slide groove 311 , so as to facilitate the stable movement of the screw slider 321 .

[0028] When the electrical membrane breakdown test device of the utility model is used, first, the electrical membrane roll 5 to be tested is placed on the top of the clamping assembly 3, and then the rotating shaft 33 is driven to rotate by the driving motor 331. The active bevel gear 332 on the rotating shaft 33 meshes with the driven bevel gear 322 at the end of the screw, thereby driving the screw 32 to rotate. The screw slider 321 on the screw 32 moves stably under the guidance of the slide groove 311, and then drives the pressure plate 34 to move toward the inside of the electrical membrane roll 5, so as to achieve a tight clamping of the electrical membrane roll 5. During the clamping process, the outer wall of the pressure plate 34 is attached to the inner wall of the top inner cavity of the electrical membrane roll 5, ensuring the stability and positioning accuracy of the electrical membrane roll 5. At the same time, the telescopic assembly 2 drives the piston rod 22 to extend through the telescopic cylinder 21, so that the insulating pad 23 crimps the wiring to the outer wall of the electrical membrane roll 5, ensuring the stability of the wiring and preventing it from loosening.

[0029] After the clamping and crimping are completed, the electrical film roll 5 is electrically connected to the experimental equipment 13 through wiring, and then the experimental equipment 13 is operated to start the breakdown test of the electrical film. During the test, the test process can be observed through the glass window 111 on the cabinet 1, so as to record and analyze the test results in time.

[0030] After the test, the experimental equipment is turned off, and then the driving motor 331 is reversed to drive the rotating shaft 33 and the screw rod 32 to rotate in the opposite direction, so that the pressing plate 34 moves outward to release the clamping of the electrical film roll 5. At the same time, the telescopic cylinder 21 drives the piston rod 22 to shorten, so that the insulating pad 23 is separated from the electrical film roll 5, which is convenient for removing the wiring and taking out the electrical film roll 5.

[0031] Finally, it should be noted that the electronic components of the telescopic cylinder 21, drive motor 331, etc. in this embodiment are all universal standard parts or parts known to those skilled in the art, and their structures and principles can be known to those skilled in the art through technical manuals or through conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires respectively, and the specific connection means should refer to the working sequence between the electrical components in the above-mentioned working principle to complete the electrical connection, which are all well-known technologies in the art.
