Description

Technical Field

[0001] This utility model relates to the field of capacitor technology, and specifically to a capacitor with a breakdown-resistant structure. Background Technology

[0002] A capacitor is a "container" for storing electric charge and plays an important role in circuits such as tuning, bypassing, coupling, and filtering. If the voltage is too high or the operation exceeds the rated load, energy will accumulate inside the capacitor, and pressure will be generated inside the capacitor. When the capacitor cannot withstand the pressure, it will break down and explode.

[0003] For example, a capacitor with a breakdown-proof structure disclosed in application number 202322344314.0 is provided with a sealing airbag. When the cover plate is pressed down, the movement of the locking rod can be controlled to ensure the smooth downward assembly of the cover plate. After the cover plate is positioned, the locking rod can be reset and moved to push the lower moving rod, control the lower piston to slide in the lower air cylinder, and inflate the sealing airbag to achieve rapid assembly and sealing of the cover plate and aluminum shell.

[0004] However, the above structure cannot effectively extract the hot air from the capacitor casing during use, thus preventing convenient and effective venting. Consequently, it cannot effectively prevent breakdown caused by overheating, reducing breakdown protection efficiency and operating efficiency. Furthermore, it cannot vent at multiple locations, further reducing venting efficiency and operating efficiency, and shortening its service life. Therefore, we propose a capacitor with a breakdown protection structure. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application proposes a capacitor with a breakdown-proof structure that can effectively and conveniently extract hot air from the capacitor casing, thereby enabling convenient and effective venting and effectively preventing breakdown caused by excessive temperature, thus improving breakdown-proof efficiency and usage efficiency.

[0006] This utility model provides the following technical solution: a capacitor with a breakdown-proof structure, including a capacitor housing, a capacitor core installed inside the capacitor housing, and leads installed at the bottom of the capacitor core. The top of the capacitor housing is open. A protective shell is fitted over the capacitor housing. A funnel tube matching the capacitor housing is fitted inside the protective shell. A vent pipe is bolted to the top of the funnel tube. A cover plate is bolted to the top of the vent pipe. An exhaust pipe is connected to the top of the cover plate.

[0007] As a preferred embodiment of this utility model, a piston block is slidably connected inside the air guide tube, and a buffer spring is bolted to the top of the piston block. The top of the buffer spring is bolted to the bottom of the cover plate.

[0008] As a preferred embodiment of this utility model, the outer wall of the air guide tube is connected to several evenly distributed air outlet tubes near the bottom, and the bottom of the air outlet tubes is attached to the top of the protective shell.

[0009] As a preferred embodiment of this utility model, the outer wall of the air guide tube is connected to several evenly distributed U-shaped tubes near the top, and the end of the U-shaped tube that is far from the air guide tube is connected to the inside of the protective shell.

[0010] As a preferred embodiment of this utility model, the protective outer shell is fitted with an inverted cylindrical body. Near the top of the inner wall of the inverted cylindrical body, several evenly distributed docking posts are bolted together. The end of each docking post that is far from the inner wall of the inverted cylindrical body is bolted to the outer wall of the air guide pipe.

[0011] As a preferred embodiment of this utility model, the top of the inverted cylinder is provided with a plurality of evenly distributed exhaust holes, and the top of the inverted cylinder is provided with a through hole that matches the air guide pipe.

[0012] The beneficial effects of this utility model are as follows: This technical solution, through the cooperation of components such as piston block, buffer spring, funnel tube, exhaust pipe and vent pipe, enables the efficient extraction of hot air from inside the capacitor shell, thereby enabling convenient and effective venting. This, in turn, effectively prevents breakdown caused by excessive temperature, improves breakdown protection efficiency and usage efficiency, and allows for multi-position venting, thus effectively expelling hot air, improving venting efficiency and working efficiency, and extending its service life.

Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0016] like Figures 1 to 7 As shown, a capacitor with a breakdown-proof structure includes: a capacitor housing 1, a capacitor core installed inside the capacitor housing 1, and pins installed at the bottom of the capacitor core, and the top of the capacitor housing 1 is open; a protective shell 2 is fitted over the capacitor housing 1; a funnel tube 11 matching the capacitor housing 1 is fitted inside the protective shell 2; a vent pipe 6 is bolted to the top of the funnel tube 11; a cover plate 4 is bolted to the top of the vent pipe 6; and an exhaust pipe 5 is connected to the top of the cover plate 4.

[0017] A piston block 13 is slidably connected inside the air duct 6. A buffer spring 12 is bolted to the top of the piston block 13. The top of the buffer spring 12 is bolted to the bottom of the cover plate 4.

[0018] In this embodiment, it can effectively extract the hot air inside the capacitor casing 1, thereby enabling convenient and effective venting, which in turn can effectively prevent breakdown caused by excessive temperature, improving breakdown protection efficiency and usage efficiency.

[0019] The outer wall of the air duct 6 is connected to several evenly distributed air outlet pipes 8 near the bottom, and the bottom of the air outlet pipes 8 is attached to the top of the protective shell 2. The outer wall of the air duct 6 is connected to several evenly distributed U-shaped pipes 10 near the top. The end of the U-shaped pipe 10 away from the air duct 6 is connected to the inside of the protective shell 2. The protective shell 2 is covered with an inverted cylinder 3. The inner wall of the inverted cylinder 3 is connected to several evenly distributed docking posts 9 by bolts near the top. The end of the docking post 9 away from the inner wall of the inverted cylinder 3 is connected to the outer wall of the air duct 6 by bolts. The top of the inverted cylinder 3 has several evenly distributed exhaust holes 7 and a through hole 14 that matches the air duct 6.

[0020] Implementation plan: This allows for multi-position exhaust, enabling effective removal of hot air, improving exhaust efficiency and working efficiency, and extending its service life.

[0021] Working Principle: During operation, the hot gas generated by the capacitor is introduced into the vent pipe 6 through the funnel tube 11, causing the piston block 13 to slide upward within the vent pipe 6 and compress the buffer spring 12, thus expelling the hot gas through the outlet pipe 8. The hot gas is then discharged through the exhaust port 7. Meanwhile, the piston block 13 slides up and down within the vent pipe 6, drawing out the hot gas through the U-shaped tube 10 and discharging it through the exhaust pipe 5. This effectively and conveniently extracts the hot gas from the capacitor casing 1, enabling efficient venting and preventing breakdown caused by overheating. This improves the breakdown protection efficiency and overall efficiency. Furthermore, the multi-position venting allows for effective hot gas discharge, enhancing venting efficiency and operational efficiency, and extending the capacitor's service life.
