Description

Technical Field

[0001] The present invention relates to a simulation device for generating an electromagnetic pulse environment, in particular to a simulation device for forming an electromagnetic pulse environment of a vertically polarized radiation wave. Background Art

[0002] High-altitude electromagnetic pulse (EMP) simulators are essential equipment for testing electronic systems' strong EMP protection capabilities and conducting strong EMP tests. Designed to meet specific requirements, these simulators provide test subjects with an EMP environment that complies with relevant standards. The amplitude, uniformity, and polarization of the generated electromagnetic environment must meet standard requirements. Simulation tests based on these simulators can assess the subject's response to specific EMP environments. Depending on the antenna type, EMP simulators can be categorized into three types: bounded wave simulators, radiated wave simulators, and hybrid radiated wave simulators.

[0003] A vertically polarized radiated wave electromagnetic pulse simulator is used to generate an electromagnetic pulse environment with a polarization direction perpendicular to the ground. It primarily consists of a pulse source and an antenna assembly. The antenna assembly typically utilizes a monoconical antenna consisting of a ground plane and an inverted conical conductor. The test subject is placed within the outward extension of the monoconical antenna. The pulse source is typically designed within the conical conductor. Depending on the output voltage level, a single-stage or two-stage pulse compression technique is selected to produce a fast-leading pulse voltage output. This voltage is fed to the monoconical antenna at the top of the conical conductor. The pulse source typically utilizes a multi-layered nested insulation structure to achieve high-voltage output. Placing the pulse source within the conical conductor above the ground reduces the amount of ground foundation construction required. However, this approach also presents certain drawbacks. For example, the pulse source, when installed outdoors, needs to be disassembled and transported back to the commissioning hall when not undergoing testing, requiring a separate transport platform. Therefore, improving the layout of the pulse source and antenna system in a vertically polarized radiated wave electromagnetic pulse simulator is crucial for the development of high-intensity electromagnetic pulse simulation technology. Summary of the Invention

[0004] The purpose of the present invention is to provide a simulation device for forming a vertically polarized radiation wave electromagnetic pulse environment. Compared with existing electromagnetic pulse simulation devices, the device reduces the complexity of device installation and debugging, saves test preparation time, and improves test efficiency. At the same time, it enhances the anti-electromagnetic interference performance of its measurement and control system and improves the insulation performance of the key component peaking capacitor.

[0021] The peaking capacitor is embedded in the center of the bottom plate;

[0022] The output switch includes a lower electrode and an upper electrode disposed above the lower electrode; the lower electrode and the upper electrode are both conical structures, and the small ends are both spherical;

[0023] The lower electrode is embedded in the middle of the peaking capacitor, with its small end facing upward and its large end electrically connected to the upper end of the middle storage switch;

[0024] The small end of the upper electrode is downward and opposite to the small end of the lower electrode. A gap is provided between the small ends of the upper electrode and the lower electrode.

[0025] Furthermore, the peaking capacitor comprises a cylindrical inner core, a fastening ring, a multi-layer electrode ring and a multi-layer thin film dielectric;

[0026] The inner core is coaxially arranged with the bottom plate, and the lower electrode is embedded in the middle of the inner core;

[0036] Furthermore, the outer wall of the fastening ring is electrically connected to the base plate via a beryllium copper spring.

[0037] Beneficial effects of the present invention:

[0038] 1. The present invention establishes an underground cavity for the Marx generator and the first-stage pulse compression unit, so that all installation and debugging work of the entire simulation device can be completed in the underground cavity. After debugging is completed, the test can be carried out directly, without the need to complete pre-installation and pre-debugging in the debugging hall on the ground and then transport it to the test site, and then re-install and debug it. This greatly shortens the preparation time for the electromagnetic pulse test, and does not require a special transfer platform designed for transporting the pulse source of the vertically polarized radiation wave electromagnetic pulse simulation device from the debugging hall to the test site, which greatly saves costs.

[0039] 2. The contour lines of the upper and lower ends of the peaking capacitor electrode ring in the present invention are perpendicular to the central axis of the inner core, that is, perpendicular to the central axis of the peaking capacitor. Therefore, the electric field on the surface of the thin-film dielectric is dominated by the component perpendicular to the central axis. This electric field distribution characteristic can significantly improve its surface flashover performance. In existing simulation devices arranged on the ground of a pulse source, in order to form a fast-front radiation field, the peaking capacitor is designed conformally with a single-cone antenna. That is, the angle between the end faces of the electrode ring and the central axis of the capacitor is equal to the half-cone angle of the antenna. At this time, there are a large number of electric field components parallel to the surface of the thin-film dielectric on the outer surface of the peaking capacitor, which makes surface flashover occur at relatively low voltages, which easily leads to the formation of flashover.

[0040] 3. For the simulation device of the present invention, all its control and measurement equipment can be installed in the underground cavity. Compared with the existing above-ground arrangement of the pulse source, since the base plate and the underground cavity form a shielded cavity and the whole is grounded, the electromagnetic interference to its control and measurement equipment will be greatly reduced.

[0041] 4. The present invention places the Marx generator, i.e., the pulse source, in the basement. After the test is completed, the main components of the pulse source are still stored in the underground cavity. After the underground cavity is sealed, the entire simulation device does not need to be transported to the above-ground debugging hall to cope with the adverse external weather environment. This makes the test more convenient and saves human resources.

[0042] 5. The present invention sets up an underground cavity, so that the pulse source - Marx generator does not need to consider the issue of lightweighting and can be placed directly on the ground in the underground cavity. Therefore, liquid insulating medium can be used for insulation. Compared with the existing gas-insulated Marx generator, the liquid medium-insulated Marx generator has better establishment characteristics. BRIEF DESCRIPTION OF THE DRAWINGS

[0048] like Figure 1 As shown, a simulation device for forming a vertically polarized radiation wave electromagnetic pulse environment includes an underground cavity 1, a monoconical antenna, a Marx generator, a first-stage pulse compression unit, and a second-stage pulse compression unit;

[0049] The underground cavity 1 is a cylindrical cavity;

[0050] The monoconical antenna includes a circular base plate 5 and a conical cylindrical conductor 7; the base plate 5 covers the top of the underground cavity 1, and the base plate 5 is made of metal material, and the upper end surface of the base plate 5 is flush with the ground; the conductor 7 is arranged above the base plate 5, with its small end facing downward and pointing to the midpoint of the base plate 5; it can be understood that the monoconical antenna is located directly above the underground cavity 1.

[0051] A Marx generator is disposed in an underground cavity 1 and is used to generate a leading-edge hundred-nanosecond pulse voltage. The Marx generator is a primary pulse source and specifically comprises a Marx cavity 4 and a core 2. The Marx cavity 4 is located on the ground within the underground cavity 1 and contains a liquid insulating medium 3. In this embodiment, the liquid insulating medium 3 is transformer oil. In other embodiments, other liquid insulating media may also be used, and the present invention is not limited thereto. The core 2 is immersed in the liquid insulating medium 3. The output end of the core 2 is electrically connected to the first-stage pulse compression unit.

[0052] The first-stage pulse compression unit is arranged between the Marx generator and the base plate 5. It can be understood that the first-stage pulse compression unit is also located in the underground cavity 1. The first-stage pulse compression unit is mainly used to perform a first-stage compression on the pulse voltage; specifically, the first-stage pulse compression unit includes an insulating barrel 6, a shielding ring 12, a storage switch 10 and a plurality of storage capacitors 11; the lower end of the insulating barrel 6 extends into the Marx cavity 4 and is located in the liquid insulating medium 3, and the upper end thereof is sealed and connected to the bottom surface of the base plate 5, so that an installation cavity is formed between the insulating barrel 6 and the base plate 5, and the installation cavity is filled with a gas insulating medium to achieve insulation under high voltage conditions; the shielding ring 12, the storage switch 10 and multiple storage capacitors 11 are all located in the installation cavity; the upper end of the storage switch 10 is electrically connected to the second-stage pulse compression unit, and the lower end is vertically connected to the center of the shielding ring 12. It should be noted that the shielding ring 12 is a solid ring, and its outer ring is a shielding ring. A circular connecting plate is provided in the middle of the shielding ring, and the outer periphery of the circular connecting plate is fixedly connected to the inner wall of the shielding ring; multiple storage capacitors 11 are evenly distributed around the storage switch 10 in a conical manner with the large end facing upward; the lower end of each storage capacitor 11 is electrically connected to the shielding ring 12, and the upper end is electrically connected to the bottom plate 5; the output end of the Marx generator passes through the bottom of the insulating barrel 6 and is electrically connected to the shielding ring 12 and the lower end of the storage switch 10.

[0053] The second-stage pulse compression unit is embedded in the center of the bottom plate 5, and is used to perform secondary compression on the pulse voltage after the first-stage compression; specifically, the second-stage pulse compression unit includes an output switch 8, a peaking capacitor 9, a first insulating tube 13, and a second insulating tube 14; the output switch 8 includes a lower electrode and an upper electrode arranged above the lower electrode; the lower electrode and the upper electrode are both conical structures, and their small ends are both spherical; the lower electrode is embedded in the middle of the peaking capacitor 9, with its small end facing upward, and its large end electrically connected to the upper end of the intermediate storage switch 10; the small end of the upper electrode is downward and opposite to the small end of the lower electrode, and a gap is provided between the small end of the upper electrode and the small end of the lower electrode, and the large end of the upper electrode is electrically connected to the lower end of the conductor 7 (i.e., the small end of the conductor 7). Since the upper electrode is a conical structure, its upper end face is circular, which just matches and connects with the lower end face of the conductor 7, so that the axis of the upper electrode and the axis of the conductor 7 are on the same straight line. Figure 2As shown, the peaking capacitor 9 includes a cylindrical inner core 9-1, a fastening ring 9-4, a multi-layer electrode ring 9-2 and a multi-layer thin film dielectric 9-3; the inner core 9-1 is coaxially arranged with the base plate 5, and the inner core 9-1 is a hollow structure, which is conducive to weight reduction. The lower electrode is specifically embedded in the middle of the inner core 9-1; the multi-layer electrode ring 9-2 and the multi-layer thin film dielectric 9-3 are spaced from the inside to the outside outside the inner core 9-1; the upper and lower end faces of the multi-layer electrode ring 9-2 are perpendicular to the central axis of the inner core 9-1, and the upper end face is flush with the ground. It should be noted that the portion of the peaking capacitor 9 in the figure that exceeds the base plate 5 is the thin film dielectric 9-3; the fastening ring 9-4 is sleeved on the outside of the multi-layer electrode ring 9-2 and the multi-layer thin film dielectric 9-3, and is mainly used to compress the multi-layer electrode ring 9-2 and the multi-layer thin film dielectric 9-3; the fastening ring 9-4 is electrically connected to the base plate 5 through a beryllium copper spring. The second-stage pulse compression unit, consisting of the output switch 8 and the peaking capacitor 9, can be installed and removed from within the underground cavity 1. A first insulating tube 13 is located above the bottom plate 5 and is mounted outside the upper electrode. Its upper end is sealed to the junction between the upper electrode and the conductor 7, and its lower end is sealed to the bottom plate 5. This creates a first sealed cavity between the first insulating tube 13, the upper electrode, the lower electrode, the peaking capacitor 9, and the bottom plate 5. This first sealed cavity is filled with a gaseous insulating medium, providing insulation under high voltage conditions. A second insulating tube 14 is located above the bottom plate 5 and is mounted outside the first insulating tube 13. Its lower end is sealed to the bottom plate 5, and its upper end is sealed to the central outer wall of the conductor 7. This creates a second sealed cavity between the second insulating tube 14, the first insulating tube 13, the conductor 7, and the bottom plate 5. This second sealed cavity is filled with a gaseous insulating medium, providing insulation under high voltage conditions.

[0054] Overall, the central axes of the underground cavity 1, the first-stage pulse compression unit, the second-stage pulse compression unit, the bottom plate 5 and the conductor 7 are all located on the same straight line.

[0055] The installation process of the simulation device provided by the present invention is as follows:

[0056] During use, an underground chamber is first constructed at the test site to accommodate the Marx generator, first-stage pulse compression unit, and other ancillary equipment. A baseplate is then fabricated, with its upper surface flush with the ground and its lower surface serving as the inner ceiling of the chamber. The Marx generator, first-stage pulse compression unit, second-stage pulse compression unit, and monoconical antenna are designed and fabricated based on the parameters of the vertically polarized radiation wave electromagnetic pulse simulator. Before the baseplate is sealed, any components of the Marx generator, first-stage pulse compression unit, and other ancillary equipment that cannot be transported through the chamber's access passage are hoisted into the chamber, and the baseplate is then installed. Smaller equipment can be transported through the chamber's access passage. The first and second insulating cylinders, as well as conductor 7, located above ground, are then mounted on the baseplate. The Marx generator and first-stage pulse compression unit are then installed in the chamber. The airtightness of each chamber is then checked and filled with a suitable insulating gas.

[0057] The simulation device provided by the present invention has the following working process:

[0058] Based on the output parameter requirements of the vertically polarized radiation wave electromagnetic pulse simulator, the parameters of the Marx generator, intermediate storage switch, and output switch are adjusted to preset values. The Marx generator is charged to the preset value and then, under the control of the auxiliary trigger system, generates a high-voltage pulse. After adjustment by the first-stage pulse compression unit and the second-stage pulse compression unit, the pulse is fed into the monoconical antenna composed of a conductor and a base plate, forming a radiation field within the monoconical antenna's radiation space.

[0059] This embodiment of the present invention optimizes the layout and structure of the pulse source and antenna of a conventional vertically polarized radiation wave electromagnetic pulse simulator. The pulse source and first-stage pulse compression unit are located in an underground cavity below a floor level with the ground. Compared to vertically polarized radiation wave electromagnetic pulse simulators with the pulse source located above ground, the present invention simplifies installation, commissioning, and storage, eliminating transportation and saving time and labor. It also improves the surface insulation of the key peaking capacitor component.
