DETAILED DESCRIPTION
[0021] 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.
[0022] The utility model provides a thin film capacitor self-healing performance testing device, such as Figure 1-Figure 3 As shown, it includes a cabinet 1, and an equipment compartment 15, a wiring compartment 16 and an experimental compartment 17 are sequentially arranged inside the cabinet 1. Clamping components 2 are installed on both sides of the interior of the experimental compartment 17. The clamping component 2 fixes the capacitor 7 in the middle of the experimental compartment 17. A mesh plate 3 is installed at the bottom of the capacitor 7. A sewage compartment 4 is arranged below the mesh plate 3 for storing sewage after flushing. A sewage pipe 41 is connected to one side of the sewage compartment 4. A smoke sensor 5 and a nozzle 6 are installed on the top inner wall of the experimental compartment 17. The nozzle 6 sprays water for cleaning and fire extinguishing operations in the experimental compartment 17. The smoke sensor 5 senses the smoke, and the nozzle 6 sprays water to extinguish the flame.
[0023] In this embodiment, a display screen 12 and a control panel 13 are installed on the upper part of the outer wall of the cabinet 1 near the wiring compartment 16, and a compartment door 14 is installed on the outer side of the cabinet 1 near the experimental compartment 17. The capacitor can be placed and taken out by opening the compartment door 14.
[0024] Specifically, a storage table 11 is installed in the middle of the front of the cabinet 1 for placing some auxiliary supplies.
[0025] Furthermore, the clamping assembly 2 includes a fixing sleeve 21 , the inner wall of which is provided with an internal thread, the internal thread of the fixing sleeve 21 is connected with a threaded rod 22 , and a pressing plate 23 is installed at the outer end of the threaded rod 22 for pressing and fixing the capacitor 7 .
[0026] Furthermore, a threading hole 18 is provided between the wiring compartment 16 and the experimental compartment 17 , and a water retaining plate 181 is installed on the outer wall of the threading hole 18 close to the experimental compartment 17 . The water retaining plate 181 is inclined to prevent water from entering.
[0027] Furthermore, a plurality of universal wheels are installed at the bottom of the cabinet 1 to facilitate the movement of the cabinet 1 .
[0028] Furthermore, the mesh plate 3 is made of metal material, and the aperture of the mesh plate 3 is 1 mm-2 mm, for water to pass downward.
[0029] Furthermore, a fireproof layer is provided on the surface of the partition between the wiring compartment 16 and the experimental compartment 17. The fireproof layer is made of asbestos tile material and can play a fireproof effect.
[0030] When the thin film capacitor self-healing performance test device of the utility model is used, first before the test, the capacitor 7 is placed in the experimental chamber 17, and the capacitor 7 needs to be wired through the wiring chamber 16. A threading hole 18 is provided between the wiring chamber 16 and the experimental chamber 17 to facilitate the passage of the wire. At the same time, a water baffle 181 is installed on the outer wall of the threading hole 18 close to the side of the experimental chamber 17 to prevent water from entering the wiring chamber 16 during cleaning or fire extinguishing, so as to ensure the safety of the wire. Then, by simulating various overvoltage, overcurrent and other conditions that may occur in the actual use of the capacitor 7, the capacitor is charged, discharged, disconnected and other operations are performed to detect whether the capacitor can self-heal. During the test, if the capacitor 7 fails to self-heal and causes a short circuit or combustion, the smoke sensor 5 on the top of the experimental chamber 17 will sense the smoke in time and send a signal. After receiving the signal, the nozzle 6 will immediately start the water spraying function to clean and extinguish the experimental chamber 17 to ensure that the fire will not spread. At the same time, water flows into the sewage tank 4 through the mesh plate 3 for storage. The aperture design of the mesh plate 3 ensures that water can pass smoothly without affecting the fixation and testing of the capacitor 7.
[0031] After the test is finished, the staff can open the door 14 again and take out the tested capacitor 7. During the whole test process, the universal wheels at the bottom of the cabinet 1 facilitate the movement and position adjustment of the equipment, thereby improving the work efficiency. In addition, the surface of the partition between the wiring compartment 16 and the experimental compartment 17 is provided with a fireproof layer made of asbestos tile material, which further enhances the safety of the equipment.
