Description

Technical Field

[0001] This invention relates to the field of pulse technology, and more particularly to a high-voltage pulse capacitor electrode lead-out device. Background Technology

[0002] High-voltage pulse capacitors are key components of pulse power supplies for novel electromagnetic weapons such as new-concept electromagnetic weapons and electric field kinetic energy weapons, and are also fundamental components of laser-induced nuclear fusion. In recent years, with the rapid development of new-concept weapons and other fields, the requirements for capacitors in pulse power systems and high-voltage, high-current pulse power supplies have become increasingly stringent. Besides high voltage, high current, and long service life, the energy storage ratio of the capacitor device is also becoming increasingly important. The energy storage ratio is the ratio of the capacitor's volume to the stored energy. Currently, most pulse capacitors, while meeting the requirements of high voltage, high current, and long service life, have a correspondingly larger volume, making it impossible to achieve a high energy storage ratio. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a high-voltage pulse capacitor electrode lead-out device to shorten the distance between the capacitor box cover and the bus copper wire.

[0004] The technical solution of the present invention to solve the above-mentioned technical problems is as follows: A high-voltage pulse capacitor electrode lead-out device includes: a busbar copper wire, a guide rod, an insulating plate, a sleeve and a box cover, wherein the guide rod and the sleeve pass through the box cover, the guide rod is disposed in the middle of the sleeve, the insulating plate is connected to the bottom end of the guide rod, and the busbar copper wire passes through the insulating plate and is connected to the bottom end of the guide rod.

[0005] The beneficial effects of this invention are: on the one hand, the positional relationship between the busbar, the guide rod, the insulating plate and the box cover helps to reduce the distance between the busbar and the box cover, thereby reducing the volume of the capacitor and improving the energy storage density of the capacitor; on the other hand, the direct connection between the busbar and the guide rod helps to improve the insulation of the capacitor electrode lead-out device and reduce safety hazards.

[0006] Based on the above technical solution, the present invention can be further improved as follows.

[0007] Furthermore, the box cover has a plate-like structure, and the box cover is provided with mounting holes and multiple eighth connecting holes. The mounting holes are through holes, and the eighth connecting holes are through holes with threads on their inner walls. The multiple eighth connecting holes surround the mounting holes.

[0008] The beneficial effects of adopting the above-mentioned further solution are: the box cover provides the necessary space for the installation of the guide rod and the sleeve, and the guide rod is located under the box cover, which facilitates the connection between the bus copper wire and the part of the guide rod under the box cover, reduces the distance between the bus copper wire and the box cover, thereby reducing the capacitor volume and increasing the energy storage density of the capacitor.

[0009] Furthermore, the guide rod includes: a first boss, a connecting plate, and a second boss. The connecting plate has a plate-like structure, and the top and bottom surfaces of the connecting plate are connected one-to-one to the bottom surface of the first boss and the top surface of the second boss.

[0010] Furthermore, the first boss and the second boss are columnar structures. The top surface of the first boss is provided with a first connecting hole, the top surface of the connecting plate is provided with a plurality of second connecting holes, the bottom surface of the second boss is provided with a plurality of third connecting holes and a plurality of fourth connecting holes. The first connecting hole, the second connecting hole and the third connecting hole are all blind holes with threads on their inner walls, the fourth connecting hole is a blind hole, and the plurality of second connecting holes surround the first boss.

[0011] The advantages of adopting the above-mentioned further solution are: the first connection hole facilitates the connection position for the capacitor and the external electrical device; the second connection hole facilitates the fixing of the sleeve and the guide rod with the external screw; the third connection hole facilitates the fixing of the insulating plate and the guide rod with the external screw; and the fourth connection hole facilitates the fixing of the bus copper wire, avoiding direct contact between the bus copper wire and the cover plate, and reducing the risk of electric shock.

[0012] Furthermore, the insulating plate includes: a threaded rod, a base plate, and a through hole. The threaded rod is a rod-shaped structure with threads on its outer side wall. The base plate is a plate-shaped structure. The bottom surface of the threaded rod is connected to the top surface of the base plate. The through hole is a through hole provided on the threaded rod and the base plate. The busbar copper wire passes through the through hole.

[0013] Furthermore, the top end of the threaded rod is provided with a plurality of fifth connecting holes, each of which is a through hole with threads on its inner wall, and the plurality of fifth connecting holes are connected to the plurality of third connecting holes one by one by screws.

[0014] The advantages of adopting the above-mentioned further solution are: on the one hand, the wire hole helps to provide the necessary channel for the bus copper wire to pass through the insulation board; on the other hand, the fifth connecting hole helps to cooperate with the third connecting hole to connect the insulation board and the guide rod with external screws, thereby minimizing the distance between the bus copper wire and the box cover.

[0015] Furthermore, the sleeve is a tubular structure with multiple grooves at the top end. The sleeve wall is provided with multiple sixth connecting holes and multiple seventh connecting holes. The sixth connecting holes and the seventh connecting holes are through holes with threads on the inner wall. The multiple sixth connecting holes are connected to the multiple second connecting holes one by one by screws. The multiple seventh connecting holes are connected to the multiple eighth connecting holes one by one by screws. The inner wall of the sleeve and the outer wall of the first boss are adapted to abut against each other.

[0016] The beneficial effects of adopting the above-mentioned further solution are: the sixth and seventh connecting holes facilitate the one-to-one connection of the bushing with the guide rod and the box cover, and the multiple grooves set at the top of the bushing help to increase the creepage distance between the box cover and the bus copper wire, thereby reducing the possibility of short circuit of the high voltage pulse capacitor device.

[0017] Furthermore, the busbar copper wire includes multiple copper wires and multiple copper tubes, with each copper tube correspondingly sleeved on one end of the multiple copper wires near the insulating plate. The copper wires and copper tubes are crimped together, and each copper tube is connected to each of the multiple fourth connecting holes.

[0018] The beneficial effects of adopting the above-mentioned further solution are: after the copper wire and copper tube are crimped, it is easier to connect multiple copper wires and the fourth connecting hole one by one, thereby reducing the distance between the bus copper wire and the box cover, thus reducing the volume of the capacitor and increasing the energy storage density of the capacitor.

[0033] The principles and features of the present invention are described below. The examples given are only for explaining the present invention and are not intended to limit the scope of the present invention.

[0034] like Figure 1 As shown, a high-voltage pulse capacitor electrode lead-out device includes: a bus copper wire 1, a guide rod 2, an insulating plate 3, a sleeve 4, and a box cover 5. The guide rod 2 and the sleeve 4 pass through the box cover 5. The guide rod 2 is disposed in the middle of the sleeve 4. The insulating plate 3 is connected to the bottom end of the guide rod 2. The bus copper wire 1 passes through the insulating plate 3 and is connected to the bottom end of the guide rod 2.

[0035] It is important to understand that "high voltage" in a high-voltage pulse capacitor electrode lead-out device refers to a voltage greater than 1000 volts during operation.

[0036] The beneficial effects of this invention are: on the one hand, the positional relationship between the busbar, the guide rod, the insulating plate and the box cover helps to reduce the distance between the busbar and the box cover, thereby reducing the volume of the capacitor and improving the energy storage density of the capacitor; on the other hand, the direct connection between the busbar and the guide rod helps to improve the insulation of the capacitor electrode lead-out device and reduce safety hazards.

[0037] Preferred, such as Figure 11 and Figure 12As shown, the box cover 5 is a plate-shaped structure. The box cover 5 is provided with mounting holes 51 and multiple eighth connecting holes 52. The mounting holes 51 are through holes, and the eighth connecting holes 52 are through holes with threads on their inner walls. The multiple eighth connecting holes 52 surround the mounting holes 51.

[0038] The advantages of adopting the above preferred solution are: the box cover provides the necessary space for the installation of the guide rod and the sleeve, and the guide rod is located under the box cover, which facilitates the connection between the bus copper wire and the part of the guide rod under the box cover, reduces the distance between the bus copper wire and the box cover, thereby reducing the capacitor volume and increasing the energy storage density of the capacitor.

[0039] Preferred, such as Figure 3 As shown, the guide rod 2 includes: a first boss 21, a connecting plate 22, and a second boss 23. The connecting plate 22 has a plate-like structure, and the top and bottom surfaces of the connecting plate 22 are connected one-to-one to the bottom surface of the first boss 21 and the top surface of the second boss 23.

[0040] Preferred, such as Figures 3 to 5 As shown, the first boss 21 and the second boss 23 are columnar structures. The top surface of the first boss 21 is provided with a first connecting hole 211, the top surface of the connecting plate 22 is provided with a plurality of second connecting holes 221, and the bottom surface of the second boss 23 is provided with a plurality of third connecting holes 231 and a plurality of fourth connecting holes 232. The first connecting hole 211, the second connecting hole 221 and the third connecting hole 23 are all blind holes with threads on their inner walls. The fourth connecting hole 232 is a blind hole. The plurality of second connecting holes 221 surround the first boss 21.

[0041] The advantages of adopting the above preferred solution are: the first connection hole facilitates the connection position for the capacitor and external electrical devices; the second connection hole facilitates the fixing of the sleeve and guide rod with external screws; the third connection hole facilitates the fixing of the insulating plate and guide rod with external screws; and the fourth connection hole facilitates the fixing of the bus copper wire, avoiding direct contact between the bus copper wire and the cover plate, and reducing the risk of electric shock.

[0042] Preferred, such as Figures 6 to 8 As shown, the insulating plate 3 includes: a threaded rod 31, a base plate 32, and a wire hole 33. The threaded rod 31 is a rod-shaped structure with threads on its outer side wall. The base plate 32 is a plate-shaped structure. The bottom surface of the threaded rod 31 is connected to the top surface of the base plate 32. The wire hole 33 is a through hole provided on the threaded rod 31 and the base plate 32. The bus copper wire 1 passes through the wire hole 33.

[0043] It is important to understand that, in the preferred embodiment, the base plate 32 is a circular plate structure, and the threaded rod 31 is a circular rod structure, with the diameter of the base plate 32 being significantly larger than the diameter of the threaded rod 31. This is done to increase the creepage distance between the cover 5 and the busbar copper wire 1, thereby reducing the possibility of a short circuit in the high-voltage pulse capacitor device.

[0044] Preferred, such as Figures 6 to 8 As shown, the top end of the threaded rod 31 is provided with a plurality of fifth connecting holes 311. The fifth connecting holes 311 are through holes with threads on their inner walls. The plurality of fifth connecting holes 311 are connected to the plurality of third connecting holes 231 one by one by screws.

[0045] The advantages of adopting the above-mentioned preferred solution are: on the one hand, the wire hole helps to provide the necessary channel for the bus copper wire to pass through the insulation board; on the other hand, the fifth connecting hole helps to cooperate with the third connecting hole to connect the insulation board and the guide rod with external screws, thereby minimizing the distance between the bus copper wire and the box cover.

[0046] Preferred, such as Figure 9 and Figure 10 As shown, the sleeve 4 is a tubular structure with multiple grooves at the top end. The sleeve 4 has multiple sixth connecting holes 41 and multiple seventh connecting holes 42 on its wall. The sixth connecting holes 41 and the seventh connecting holes 42 are through holes with threads on their inner walls. The multiple sixth connecting holes 41 are connected to the multiple second connecting holes 221 one by one by screws, and the multiple seventh connecting holes 42 are connected to the multiple eighth connecting holes 52 one by one by screws. The inner wall of the sleeve 4 and the outer wall of the first boss 21 are adapted to abut against each other.

[0047] The advantages of adopting the above preferred solution are: the sixth and seventh connecting holes facilitate the one-to-one connection of the bushing with the guide rod and the box cover, and the multiple grooves set at the top of the bushing help to increase the creepage distance between the box cover and the bus copper wire, thereby reducing the possibility of short circuit of the high voltage pulse capacitor device.

[0048] Preferred, such as Figure 2 As shown, the busbar copper wire 1 includes multiple copper wires 11 and multiple copper tubes 12. The multiple copper tubes 12 are sleeved one-to-one on one end of the multiple copper wires 11 near the insulating plate 3. The copper wires 11 and copper tubes 12 are crimped together. The multiple copper tubes 12 are connected one-to-one with the multiple fourth connecting holes 232.

[0049] It should be understood that, in the preferred embodiment, the copper wire 11 is a tin-plated copper wire, and the end of the copper wire 11 that is not sleeved on the copper tube 12 is fixed by soldering with tin to prevent the copper wire 11 from becoming loose.

[0050] The advantages of adopting the above preferred solution are: after the copper wire and copper tube are crimped, it is convenient to connect multiple copper wires and the fourth connecting hole one by one, thereby reducing the distance between the bus copper wire and the box cover, thus reducing the volume of the capacitor and increasing the energy storage density of the capacitor.
