Description

Technical Field

[0001] This invention belongs to the field of electromagnetic launch technology, and specifically relates to an electromagnetic launch pulse power supply module and pulse power supply system. Background Technology

[0002] Electromagnetic launch works by using electromagnetic force to drive a load, converting electromagnetic energy into the kinetic energy of an armature. Currently, the applications of electromagnetic launch are becoming increasingly widespread. Compared to traditional launch methods, electromagnetic launch technology utilizes electromagnetic energy to accelerate the load, offering advantages such as high speed and high safety. Furthermore, by controlling the electrical energy, the launch load's exit speed can be controlled, making the launch more stable. This has become a mainstream development trend for future combat weapons.

[0003] The pulse power supply system, as the energy source of the electromagnetic launch system, plays a crucial role. Electromagnetic launch converts electrical energy into the kinetic energy of the projectile, and the power supply system, as the energy storage system of the electromagnetic launch device, determines the launch capability.

[0004] Existing pulse power module structures generally use capacitors as the load-bearing base, with all other components sitting on top of the capacitors. This is not conducive to use and maintenance. Furthermore, when multiple pulse power modules are used together, they are usually installed in containers, which is inconvenient for transportation and use, and also brings problems such as difficulty in power module maintenance. Summary of the Invention

[0005] Based on the above analysis, the present invention aims to provide an electromagnetic emission pulse power supply module and a pulse power supply system to solve the problem that existing pulse power supply modules are not conducive to use and maintenance.

[0006] The objective of this invention is mainly achieved through the following technical solutions:

[0007] An electromagnetic emission pulse power supply module includes a pulse capacitor, an electrical module, and a busbar device. The pulse capacitor is charged to a set voltage by constant current to store the electrical energy required for electromagnetic emission, and can perform rapid pulse discharge to the electromagnetic emission device through the electrical module and the busbar device.

[0008] Furthermore, the electrical module includes a housing, which includes an insulating shell and a reinforcing plate. The reinforcing plate includes a reinforcing base plate and a reinforcing left side plate, which are respectively attached to the outer sides of the insulating base plate and the insulating left side plate of the insulating shell.

[0009] Furthermore, the pulse capacitor is connected to the reinforced left side plate via a capacitor insulation plate, and the positive and negative terminals of the pulse capacitor extend into the electrical module through the insulating left side plate.

[0010] Furthermore, the electrical module includes a switching assembly, which is connected to the positive and negative terminals of the pulse capacitor via a first copper busbar and a second copper busbar, respectively.

[0011] Furthermore, the electrical module also includes a first discharge switch and a first discharge resistor, wherein the first discharge switch can be closed under the control of an external circuit, and the energy in the pulse capacitor is absorbed through the first discharge resistor.

[0012] Furthermore, the busbar includes a bracket, a copper conductor, and a pressure block. The coaxial cable is fixed to the bracket via the pressure block, the pressure block is connected to the copper conductor, and the copper conductor is connected to the switch assembly.

[0013] Furthermore, the bracket includes a first insulating plate, a second insulating plate, and a support plate. The support plate includes a horizontal plate and a vertical plate that are perpendicular to each other. The first insulating plate and the second insulating plate are respectively attached to both sides of the vertical plate.

[0014] Furthermore, the cross plate is connected to the reinforcing base plate.

[0015] Furthermore, the combiner device also includes a flange sleeve, which includes a positive flange sleeve and a negative flange sleeve, respectively fitted around the outer periphery of the positive and negative wire harnesses of the coaxial cable.

[0016] A pulse power supply system includes a cabinet, a high-voltage charger, and the power module described in the above technical solution.

[0017] This invention can achieve at least one of the following beneficial effects:

[0019] (2) The current collection device of the present invention is provided with a conductive sleeve, which connects the pressure block and the copper conductor. The conductive sleeve is interference-fitted with the pressure block and the copper conductor, so that the pressure block, the conductive sleeve and the copper conductor form an integral structure under the action of the bolt preload, thereby enabling the current to be smoothly conducted and avoiding the generation of spike discharge when a large current flows through instantaneously.

[0020] (3) The current combining device of the present invention is provided with a positive flange sleeve and a negative flange sleeve, which are respectively sleeved on the outside of the positive wire harness and the negative wire harness of the coaxial cable. The flange plates of the flange sleeve are respectively clamped on the upper end of the positive pressure block and the lower end of the negative pressure block. On the one hand, the wire harness of the coaxial cable is not squeezed, and on the other hand, the coaxial cable is limited. Even when the cable is dragged by strong electric force, the movement of the coaxial cable in the axial direction is prevented, thereby avoiding damage to the cable core and increasing the safety of the whole system.

[0021] (4) The pulse power module of the present invention has a compact structure, occupies little space, and can be inserted into the cabinet for use, making it suitable for different electromagnetic launch systems.

It is understood that the device is multifunctional and independent of its spatial orientation.

[0052] Example 1

[0053] One embodiment of the present invention, such as Figures 1 to 10 As shown, an electromagnetic emission pulse power supply module is disclosed, including a pulse capacitor 3, an electrical module 2, and a busbar device 1. The pulse capacitor 3 is charged to a set voltage by constant current to store the electrical energy required for electromagnetic emission, and can perform rapid pulse discharge to the electromagnetic emission device through the electrical module 2 and the busbar device 1.

[0054] Specifically, the electrical module 2 is equipped with an outer casing, which is made of an insulating board to ensure reliable insulation between the electrical components inside the electrical module 2 and the external chassis.

[0055] Furthermore, since the electrical components are subjected to strong electrodynamic forces during the discharge process of the pulse power module, the housing also includes reinforcing plates to provide reliable support for the electrical components.

[0056] In this embodiment, the reinforcing plate includes a reinforcing base plate 207 and a reinforcing left side plate 210, which are respectively attached to the outside of the insulating base plate 205 and the insulating left side plate 209.

[0057] In this embodiment, the reinforcing base plate 207 and the reinforcing left side plate 210 are made of stainless steel, and the reinforcing base plate 207 and the reinforcing left side plate 210 are an integral structure.

[0058] Furthermore, the pulse capacitor 3 is connected to the reinforced left side plate 210 via the capacitor insulation plate 301, ensuring the structural strength of the pulse capacitor 3 while enhancing the insulation performance between the pulse capacitor 3 and the electrical module 2. The positive and negative terminals of the pulse capacitor 3 extend into the electrical module 2 through the insulating left side plate 209.

[0059] Furthermore, the electrical module 2 includes a switch assembly 202, which is fixed on the reinforcing base plate 207.

[0060] Furthermore, the switching assembly 202 includes a first copper busbar 2021 and a second copper busbar 2022. One end of the first copper busbar 2021 is fixedly connected to the switching assembly 202, and the other end is fixedly connected to the positive terminal of the pulse capacitor 3. One end of the second copper busbar 2022 is fixedly connected to the switching assembly 202, and the other end is fixedly connected to the negative terminal of the pulse capacitor 3. Thus, the discharge of the pulse capacitor 3 is controlled by the switching assembly 202.

[0061] Furthermore, the electrical module 2 also includes a trigger box 203 and a first discharge switch 204. The first discharge switch 204 is fixed on the insulating base plate 205, and the trigger box 203 is fixed on the top plate of the first discharge switch 204 and connected to the switch assembly 202 to control the thyristor in the switch assembly 202 to conduct and trigger the control circuit.

[0062] Furthermore, the electrical module 2 also includes a first bleed resistor 206, which has a nylon base. The nylon base is nested together with the first bleed resistor 206 and placed on the insulating base plate 205, thereby improving the insulation between the first bleed resistor 206 and the reinforcing base plate 207.

[0063] In this embodiment, when the power module finishes discharging and the pulse capacitor 3 still has residual electrical energy, the first discharge switch 204 closes under the control of the external circuit, and the energy in the pulse capacitor 3 is absorbed through the first discharge resistor 206, thereby protecting the safety of the equipment and personnel.

[0064] Furthermore, the electrical module 2 also includes an inductor 208, which is fixed to the reinforcing base plate 207 by an inductor fixing member 2081, an inductor insulating pad 2082, and a double-ended screw 2083. One end of the double-ended screw 2083 passes through the inductor fixing member 2081, and the other end passes through the reinforcing base plate 207. Both ends are tightened simultaneously with nuts to fix the inductor 208.

[0065] Furthermore, the inductor 208 is connected to the switching assembly 202 via a copper busbar. When the pulse capacitor 3 discharges, the inductor 208 can change the pulse width of the pulse current to meet the current requirements of electromagnetic emission. At the same time, the inductor 208 can store some energy for use in the freewheeling branch.

[0066] In this embodiment, the busbar device includes a bracket, a copper conductor, and a pressure block. The coaxial cable 108 is fixed to the bracket by the pressure block. The pressure block is connected to the copper conductor, and the copper conductor is connected to the switch assembly 202. During power operation, the coaxial cable 108 can be completely secured to the copper conductor, thereby providing a reliable power output structure for the electromagnetic launch system.

[0067] Specifically, the bracket includes a first insulating plate 101, a second insulating plate 102, and a support plate 107. The support plate 107 is L-shaped and includes a horizontal plate and a vertical plate. The first insulating plate 101 and the second insulating plate 102 are respectively attached to the two sides of the vertical plate.

[0068] Furthermore, the horizontal plate is fixedly connected to the reinforcing base plate 207, thereby supporting the busbar device 1.

[0069] Furthermore, the width of the first insulating plate 101 is the same as the width of the second insulating plate 102, the width of the vertical plate is less than the width of the first insulating plate 101, and the vertical plate is located in the middle of the width direction of the first insulating plate 101 and the second insulating plate 102.

[0070] Furthermore, a third insulating plate 103 and a fourth insulating plate 104 are respectively provided on both sides of the vertical plate in the width direction. That is to say, the third insulating plate 103 and the fourth insulating plate 104 are located in the gap formed between the first insulating plate 101 and the second insulating plate 102, and the first insulating plate 101, the second insulating plate 102, the third insulating plate 103 and the third insulating plate 104 enclose the vertical plate in the front-back and left-right directions.

[0071] For example, the first insulating plate 101, the second insulating plate 102, the third insulating plate 103 and the fourth insulating plate 104 are epoxy resin plates, and the support plate 107 is a stainless steel plate. While ensuring the electrical insulation of the bracket, the support strength of the bracket is improved so as to ensure that the bracket can withstand the impact of the electric force during discharge.

[0072] Furthermore, the clamping block includes a positive clamping block 112 and a negative clamping block 110, which are respectively connected to the positive and negative wire harnesses of the coaxial cable 108, and clamp the coaxial cable 108 onto the bracket.

[0073] Furthermore, the copper conductor includes a positive copper block 105 and a negative copper block 106, which are respectively in close contact with the outer side of the second insulating plate 102.

[0074] Specifically, the positive copper block 105 is connected to the positive pressure block 112, and the negative copper block 106 is connected to the negative pressure block 110, thereby connecting the coaxial cable 108 to the power supply.

[0075] Furthermore, the positive copper block 105 is connected to the switch assembly 202 via a copper busbar, and the negative copper block 106 is connected to the inductor 208 via a copper busbar.

[0076] Furthermore, it also includes a positive electrode pressure plate 111 and a negative electrode pressure plate 109. The positive electrode harness of the coaxial cable 108 is located between the positive electrode pressure block 112 and the positive electrode pressure plate 111. The positive electrode pressure block 112 is connected to the positive electrode copper block 105 by two first bolts. The first bolts pass through the first insulating plate 101, the third insulating plate 103 / fourth insulating plate 104 and the second insulating plate 102 respectively. The positive electrode pressure plate 111 and the positive electrode pressure block 112 are connected by bolts, and the positive electrode harness is compressed by the preload of the bolts.

[0077] Similarly, the negative electrode harness of the coaxial cable 108 is located between the negative electrode pressure block 110 and the negative electrode pressure plate 109. The negative electrode pressure block 110 is connected to the negative electrode copper block 106 by two second bolts, and the negative electrode pressure plate 109 and the negative electrode pressure block 110 are connected by bolts. The negative electrode harness is compressed by the preload of the bolts.

[0078] In this embodiment, a flange sleeve is also provided to protect the copper core wire of the coaxial cable 108 and prevent the copper core wire from being damaged by the impact of the high voltage discharge of the pulse power supply.

[0079] Furthermore, the flange sleeve includes a positive flange sleeve 113 and a negative flange sleeve 114, which are respectively soldered and sealed to the positive and negative wire harnesses of the coaxial cable 108.

[0080] Specifically, the positive electrode flange 113 includes a first sleeve and a first flange plate. The first flange plate is located at the upper end of the first sleeve, and the first sleeve is fitted over the outside of the positive electrode harness. The cylindrical surface of the first sleeve is subjected to a clamping force under the fastening action of the positive electrode pressure block 112 and the positive electrode pressure plate 111.

[0081] Furthermore, the negative electrode flange sleeve 114 includes a second sleeve and a second flange plate. The second flange plate is located at the lower end of the second sleeve, and the second sleeve is fitted over the outside of the negative electrode harness. The cylindrical surface of the second sleeve is subjected to clamping force under the fastening action of the negative electrode pressure block 110 and the negative electrode pressure plate 109.

[0082] After the coaxial cable 108 is pressed onto the bracket by the clamping device, the first flange plate and the second flange plate are respectively clamped at the upper end of the positive clamping device and the lower end of the negative clamping device, which limit the movement of the coaxial cable 108. Even when the cable is dragged by strong electric force, the first flange plate and the second flange plate are respectively clamped at the upper end of the positive clamping device and the lower end of the negative clamping device, preventing the coaxial cable 108 from moving in the axial direction, thereby avoiding damage to the cable core and increasing the safety of the entire system.

[0083] In this embodiment, a conductive sleeve 115 is also provided to enhance the conductivity between the power supply and the coaxial cable 108. Specifically, four conductive sleeves 115 are provided, which are respectively fitted around the outer periphery of the first bolt and the second bolt. The length of the conductive sleeve 115 is greater than the total thickness of the first insulating plate 101, the second insulating plate 102 and the third insulating plate 103. The two ends of the conductive sleeve 115 are respectively interference-fitted with the positive electrode block 112 / negative electrode block 110 and the positive electrode copper block 105 / negative electrode copper block 106 to ensure that the positive electrode block 112, the conductive sleeve 115 and the positive electrode copper block 105 / negative electrode block 110, the conductive sleeve 115 and the negative electrode copper block 106 form an integral structure under the action of the bolt preload, which facilitates the transmission of current and allows the current to be transmitted smoothly between the positive electrode block 112 and the positive electrode copper block 105 or the negative electrode block 110 and the negative electrode copper block 106. There will be no spike discharge when a large current flows through instantaneously, thus avoiding the burning of the busbar device.

[0084] For example, the conductive sleeve 115 is a copper sleeve, thereby improving conductivity.

[0085] Optionally, the positive electrode pressure block 112 and the positive electrode copper block 105 are an integral structure. Specifically, the first insulating plate, the third / fourth insulating plate and the second insulating plate have openings at the locations where the positive electrode pressure block is installed, and the positive electrode pressure block 112 and the positive electrode copper block 105 are connected as one unit at the openings, thereby ensuring the stability of current transmission directly between the power supply and the coaxial cable.

[0086] Similarly, optionally, the negative electrode pressure block 110 and the negative electrode copper block 106 are an integral structure.

[0087] In this embodiment, the insulating right side plate 211 of the outer casing is provided with a mounting hole for the busbar device 1. The coaxial cable 108 is located on the outside of the outer casing, connects to the electromagnetic transmitter, and outputs current to the electromagnetic transmitter through the busbar device 1.

[0088] Furthermore, the pulse power module of this embodiment also includes an input connector 201, which is disposed on the insulating right side plate 211 and connected to the positive terminal of the pulse capacitor 3. The input connector 201 is connected to an external high-voltage power supply for charging the pulse capacitor 3.

[0089] The current combiner of this invention is fixed within the pulse power module by a composite multi-layered support structure composed of a stainless steel plate bracket and an epoxy resin plate, which improves the support strength while ensuring electrical insulation. By incorporating a conductive sleeve 115 and a flange, the current combiner improves conductivity while protecting the core of the coaxial cable 108, thus extending the system's lifespan. The pulse power module provided by this invention has a compact structure, small footprint, and can be inserted into a cabinet for use, making it suitable for various electromagnetic launch systems.

[0090] Example 2

[0091] One embodiment of the present invention, such as Figures 11 to 18 As shown, a pulse power supply system is disclosed, including a cabinet, a high-voltage charger 14, and a power module 20 of Embodiment 1.

[0092] In this embodiment, the high-voltage charger 14 and the power module 20 are both installed in the cabinet. Multiple cabinets are connected in parallel. The multiple cabinets and the internal circuits of each cabinet are connected and exchanged through high and low voltage electrical connectors, optical fibers and network cables.

[0093] For example, the pulse power system of this embodiment adopts a layout of four cabinets arranged side by side, namely the first cabinet 4, the second cabinet 5, the third cabinet 6, and the fourth cabinet 7. Among them, the first cabinet 4, the second cabinet 5, and the third cabinet 6 are equipped with power modules 20, and the fourth cabinet 7 is equipped with a high-voltage charger 14.

[0094] In this embodiment, the high-voltage charger 14 can charge the pulse capacitor 3 in the power module 20.

[0095] For example, two power modules 20 are installed in each of the first rack 4 and the second rack 5, and the two power modules 20 are arranged vertically. One power module 20 is installed in the third rack 6.

[0096] Furthermore, the fourth cabinet 7, from top to bottom, houses a battery charger 12, a lithium battery pack 13, a high-voltage charger 14, and a power distribution box 15. The power distribution box 15 provides 380V AC power to the battery charger 12. The battery charger 12, through a control system, switches between AC and DC power to DC charge the lithium battery pack 13, which is used for energy storage. When the pulse power system is operating, the lithium battery pack 13 charges the pulse capacitor 3 in the power module 20 via the high-voltage charger 14.

[0097] Furthermore, the cabinet door of the fourth cabinet 7 is equipped with a display and control panel 8 and a system master switch 9. The display and control panel 8 can detect various data statuses during the operation of the power system, and the system master switch 9 provides power-on and power-off protection for the power system.

[0098] Furthermore, a primary protection combination box 11 is also provided to protect the power module 20.

[0099] In this embodiment, the primary protection combination box 11 is installed inside the third cabinet 6. The primary protection combination box 11 contains a second discharge switch and a second discharge resistor, which employ the highest level of control and protection logic. When the first discharge switch 204 or the first discharge resistor 206 inside the power module 20 fails, safe discharge can be achieved through the second discharge switch and the second discharge resistor within the primary protection combination box 11, thereby protecting the safety of equipment and personnel.

[0100] Furthermore, the power module 20 is fixed inside the cabinet via the power module box 10. The power module box 10 includes a power chassis cover 19 and a power chassis shell 21. The power module 20 is fixed inside the power chassis shell 21, and the power chassis cover 19 is fixedly connected to the power chassis shell 21.

[0101] Furthermore, ventilation slots are provided on both the power supply chassis cover 19 and the power supply chassis shell 21 to facilitate heat dissipation of the power supply module 20.

[0102] Furthermore, the inner surface of the front panel of the power supply chassis 21 is provided with an insulating plate to insulate the power module box 10 from the exposed pressure block in the power module 20. The coaxial cable 108 of the power module 20 passes through the bottom plate of the power supply chassis 21 and is connected to the load of the electromagnetic pulse emission.

[0103] In this embodiment, the cabinet is a frame structure, including a top plate, a bottom plate, a rear side plate, four parallel columns, and multiple reinforcing rods. The columns connect the top plate and the bottom plate, and the rear side plate is installed between two of the columns. A first resonant shock absorber 16 and a second resonant shock absorber 17 are respectively installed on the bottom plate and the rear side plate of the cabinet for vehicle-mounted shock absorption.

[0104] Furthermore, each cabinet is equipped with lifting rings 18 on its top plate for easy hoisting.

[0105] Furthermore, to facilitate the installation and positioning of the power module 20 chassis, taking the first cabinet 4 as an example, the first cabinet 4 has two pairs of guide rails 26 installed inside, each pair of guide rails 26 corresponding to one power module box 10. The guide rails 26 are fixed on the left and right sides inside the cabinet.

[0106] In this embodiment, the guide rail 26 includes a connecting plate 261 and a receiving plate 262. The connecting plate 261 and the receiving plate 262 are perpendicular to each other. The two ends of the connecting plate 261 are fixedly connected to the front and rear columns of the cabinet. The bottom of the receiving plate 262 is provided with reinforcing ribs. The power module box 10 is placed on the receiving plate 262.

[0107] Furthermore, the connecting plate 261 is provided with a limit block 263, which restricts the displacement of the power module box 10 in the left and right directions of the cabinet after the power module box 10 is installed.

[0108] Furthermore, a positioning plate 24 is provided on the inner surface of the rear panel of the cabinet, and a positioning pin is provided on the positioning plate 24. A chassis positioning sleeve 22 is provided on the rear panel of the power supply chassis 21. The chassis positioning sleeve 22 cooperates with the positioning pin to facilitate the positioning of the power module box 10 during installation.

[0109] After the power module box 10 is installed in the cabinet, the front panel of the power chassis shell 21 is fixedly connected to the cabinet column by bolts, thereby fixing the power module box 10.

[0110] Similarly, the second cabinet has two pairs of guide rails 26 installed inside to support the power module box 10.
