[0002] During the aircraft lightning current test, the lightning current generator is a device that generates the waveform required for the aircraft lightning protection identification experiment. Since the lightning current generator is a high-voltage device during the test, it needs to be placed in an open area. In addition, during the discharge of the lightning current generator, the insulation capacity of the device affects the parameters of the lightning current waveform, causing the waveform generated by the lightning current generator to fail to meet the standard requirements. The generation of the lightning current slow D wave requires a high-voltage DC environment. Therefore, during the test, it is necessary to ensure the insulation between the lightning current generator and the ground, and also to realize the generator discharge circuit control function in a high-voltage environment.

DETAILED DESCRIPTION

[0033] The subject matter described herein will now be discussed with reference to example embodiments. It should be understood that the discussion of these embodiments is only to enable those skilled in the art to better understand and implement the subject matter described herein, and the functions and arrangements of the elements discussed may be changed without departing from the scope of protection of the contents of this specification. Each example may omit, replace or add various processes or components as needed. In addition, the features described relative to some examples may also be combined in other examples.

[0034] like Figures 1 to 9As shown, a lightning current D-wave slow rising edge measuring device with a protective function described in an embodiment of the present invention includes a pneumatic high-voltage discharge switch 4, wherein the pneumatic high-voltage discharge switch 4 includes a bottom square plate 41, on the top of which a first insulating ceramic column 42 and a second insulating ceramic column 43 are fixedly installed, and a rubber support block 47 is fixedly installed on the top of the second insulating ceramic column 43, and a first contact ball 44 is slidably installed on the side of the rubber support block 47, and a connecting support plate 46 is fixedly installed on the top of the first insulating ceramic column 42, and a second contact ball 45 is fixedly installed on the end of the connecting support plate 46, and an isolation device 100 is fixedly installed on the top of the connecting support plate 46, and the isolation device 100 includes: a first isolation plate fixedly installed on the top of the isolation device 100 101; a first telescopic rod 102 fixedly mounted on the side wall of the first isolation plate 101; a side isolation plate 108 fixedly mounted at the end of the first telescopic rod 102; a rotating rod 104 fixedly mounted on the side of the side isolation plate 108; a first side plate 103 rotatably mounted on the outer wall of the isolation side plate 106, the two first side plates 103 and the side isolation plate 108 form a cavity, the side isolation plate 108 and the bottom of the first side plate 103 are provided with openings that mesh with the bottom of the second contact ball 45, the inside of the side isolation plate 108 is provided with a sleeve device 300, the sleeve device 300 includes a rubber sleeve 303 and a sleeve member 302, the sleeve member 302 drives the rubber sleeve 303 to sleeve and seal the second contact ball 45.

[0035] It should be noted that the pneumatic high-voltage discharge switch 4 is connected with a high-voltage capacitor group 1, a capacitor high-voltage end charging electrode 2, a high-voltage capacitor outlet terminal 3, a current sensor 5, a current sensor ground insulation support structure 6, a high-voltage capacitor group connection aluminum bar 7, a grounding aluminum bar 8, and a high-voltage wave modulation impedance 9;

[0036] The high-voltage capacitor group 1 is divided into an upper capacitor group and a lower capacitor group, which are fixedly installed on an I-beam base respectively. The upper capacitor group and the lower capacitor group are connected in series through a high-voltage capacitor group connecting aluminum bar 7 to improve the DC withstand voltage level of the capacitor group. The I-beam base is insulated from the ground through an insulating support to prevent the capacitor group from breaking down and discharging to the ground. The charging electrode 2 at the high-voltage end of the capacitor is connected to the output end of the DC high-voltage power supply. The high-voltage capacitor group 1 is charged by the DC high-voltage power supply. The high-voltage end of the high-voltage capacitor group 1 is connected in series with a high-voltage wave modulation impedance 9 to meet the lightning slow D wave front time requirement. The high-voltage capacitor outlet 3 connected to the high-voltage wave modulation impedance 9 is connected to a pneumatic high-voltage discharge switch 4 through a wire to form a controllable discharge front end loop. The outlet end of the pneumatic high-voltage discharge switch 4 is connected to the high-voltage discharge loop to the grounding aluminum bar 8 at the grounding end through a wire. The current sensor 5 is fixed on the current sensor ground insulation support structure 6. The current sensor 5 is used to measure the current waveform in the loop and transmit the signal to the oscilloscope;

[0037] The pneumatic high-voltage discharge switch 4 is provided with a first contact ball 44, a second contact ball 45, a rubber support block 47, a first insulating ceramic column 42, and a bottom square plate 41; the first contact ball 44 is pneumatically controlled by the solenoid valve, and the first contact ball 44 connected to its top can be moved up and down, the first contact ball 44 is connected to the discharge circuit through a wire, the first contact ball 44 is fixed to one side of the triangular rubber support block 47, the triangular rubber support block 47 plays the role of insulation and preventing the pneumatic compression tube from shaking, the rubber support block 47 is fixed on the second insulating ceramic column 43, to prevent the pneumatic switch electrode of the discharge circuit from discharging to the ground, the second contact ball 45 is fixed on the insulating ceramic column, and the pneumatic switch is fixed on the bottom square plate 41 as a whole, so that the high-voltage switch can be stably controlled as a whole;

[0038] The support structure includes an I-beam base 10 for installing the upper and lower high-voltage capacitor groups. Since the upper capacitor group is connected in series with the lower capacitor group, when DC charging, the overall voltage level of the high-voltage capacitor group is U, and the voltage level at the bottom of the upper capacitor group is U / 2. Therefore, the I-beam base 10 for installing the upper high-voltage capacitor group needs to be fixed on the insulating support structure 11 of the capacitor base at the bottom of the high-voltage capacitor group and insulated from the ground. Since the capacitor group installation base is a metal structure, the lower high-voltage capacitor group is on the insulating support structure 12 of the capacitor base at the bottom of the lower high-voltage capacitor group, so that the overall capacitor group can be insulated from the ground.

[0039] Since the entire device is built in an open area, the second contact ball 45 and the first contact ball 44 need to be protected after use to prevent the first contact ball 44 and the second contact ball 45 from being corroded and rusted by the impact of the external environment, so that when the device is tested again, errors in current detection and increased resistance may occur. In order to solve this problem, the following improvements are made:

[0040] Two first side plates 103 and a side isolation plate 108 are arranged at the top of the connecting support plate 46. The first side plates 103 and the side isolation plates 108 can enclose a sealed cavity as a whole, and the bottom is provided with an opening suitable for the bottom shape of the second contact ball 45, so as to drive the first side plates 103 and the side isolation plates 108 to seal during the movement, and the first side plates 103 and the side isolation plates 108 are connected by the rotating rod 104. In the initial state, the isolation device 100 is in a state as follows: Figure 4After the inspection is completed, the first telescopic rod 102 is started, and the first telescopic rod 102 drives the first side plate 103 and the side isolation plate 108 to move in the direction close to the second contact ball 45. During the movement, the motor can be used to drive the first side plate 103 to rotate, and the first side plate 103 rotates with the rotating rod 104 as the axis to a position away from the bottom axis of the side isolation plate 108. After rotating 90°, the first side plate 103 is opened and the rotation of the first side plate 103 is stopped. Then, when the bottom end of the side isolation plate 108 is engaged with the lower end cylinder of the second contact ball 45, the motor is started again to drive the first side plate 103 to rotate, so that the first side plate 103 moves with the rotating rod 104 as the axis to the bottom axis close to the side isolation plate 108, so as to achieve the effect of sealing the second contact ball 45, prevent the second contact ball 45 from being exposed to the air after use and causing corrosion, and reduce errors in the inspection process.

[0041] like Figure 5 , Figures 7 and 8 As shown, the isolation device 100 also includes: a bottom isolation plate 107 fixedly installed at the bottom end of the connecting support plate 46; a bottom isolation rod 105 fixedly installed at the bottom end of the first side plate 103, the minimum distance between the two bottom isolation rods 105 is less than the width of the bottom isolation plate 107, and the maximum distance between the two bottom isolation rods 105 is equal to the width of the bottom isolation plate 107.

[0042] It should be noted that, considering that it is inconvenient to always use the motor to drive the first side plate 103 to rotate during use, a bottom isolation rod 105 is provided at the bottom end of the edge of the first side plate 103, and a bottom isolation plate 107 is provided at the bottom end of the connecting support plate 46, so that when the first telescopic rod 102 drives the first side plate 103 and the side isolation plate 108 to move along the length direction of the connecting support plate 46, the bottom isolation rod 105 is acted upon by the bottom isolation plate 107 to open the first side plate 103, and when the bottom side wall of the side isolation plate 108 is engaged with the lower side wall of the second contact ball 45, the first side plate 103 is in the bottom isolation plate 107. The plate 107 and the bottom isolation rod 105 are closed and sealed, thereby achieving the effect of sealing the second contact ball 45, and the minimum distance between the two bottom isolation rods 105 is less than the width of the bottom isolation plate 107, and the maximum distance between the two bottom isolation rods 105 is equal to the width of the bottom isolation plate 107, so that the bottom isolation rod 105 can be squeezed by the bottom isolation plate 107 during the movement, thereby achieving the purpose of adjusting the first side plate 103, and a torsion spring is provided at the connection between the isolation side plate 106 and the rotating rod 104, so that under normal conditions, the first side plate 103 and the side isolation plate 108 are in a closed state.

[0043] like Figures 6 to 8As shown, a third transmission plate 205 is fixedly installed on the side wall of the side isolation plate 108, and a sleeve device 300 is rotatably installed inside the third transmission plate 205. The sleeve device 300 includes: a power rotating bin 301 fixedly installed inside the third transmission plate 205; a sleeve limiting column 305 rotatably installed at the bottom end of the power rotating bin 301, and the bottom end of the sleeve limiting column 305 is rotatably installed with the sleeve member 302.

[0044] It should be noted that, considering that the second contact ball 45 may be adhered to the surface by bird droppings and dust when in use and exposed to the environment, the surface of the second contact ball 45 may be corroded. When the second contact ball 45 is used again, the resistance may increase and the conductivity may decrease. Therefore, a third transmission plate 205 is provided on the side wall of the side isolation plate 108, and a power rotating chamber 301 is provided inside the third transmission plate 205. When it is necessary to seal and isolate the second contact ball 45 from oxygen, the first side plate 103 and the side isolation plate 108 are moved to seal the second contact ball 45. The bottom end of the power rotating chamber 301 is provided with a sleeve 302, a rubber sleeve 303 and a sleeve limit column 305. The sleeve limit column 305 is driven to rotate by a motor. The center of the sleeve limit column 305 coincides with the axis of the second contact ball 45, thereby driving the sleeve 302 to rotate, so that the sleeve 302 drives the rubber sleeve 303 to seal the outer wall of the second contact ball 45, thereby completing the effect of sealing and isolating oxygen.

[0045] like Figures 4 to 7 As shown, the sleeve member 302 includes a sleeve ring 3021 fixedly installed at the bottom end of the power rotating warehouse 301 through a rod, two sleeve power columns 3023 are rotatably installed inside the sleeve ring 3021, a transmission gear 3022 is fixedly installed on one end of the sleeve power column 3023, and a sleeve rotating ring 3024 is fixedly installed on the other end of the sleeve power column 3023, a second power block 3025 is rotatably installed inside the sleeve rotating ring 3024, and an adjusting ball 3026 is movably installed inside the second power block 3025, and the outer wall of the adjusting ball 3026 is fixedly installed with the rubber sleeve 303, and two arc strips 3027 are rotatably installed on the outer wall of the sleeve ring 3021, and teeth 3028 are fixedly installed on the side walls of the arc strips 3027, and the teeth 3028 are meshed with the transmission gear 3022 and the gears arranged on the outer wall of the sleeve limit column 305.

[0046] It should be noted that when the sleeve limit column 305 rotates, the arc-shaped bar 3027 on the outer wall of the sleeve ring 3021 is driven to move, and the movement of the arc-shaped bar 3027 drives the transmission gear 3022 to rotate, thereby driving the sleeve power column 3023 and the sleeve rotating ring 3024 to rotate. The rotation of the sleeve rotating ring 3024 drives the second power block 3025 and the adjustment ball 3026 to descend along the outer wall of the second contact ball 45, thereby driving the rubber sleeve 303 to expand and contract. The rubber sleeve 303 is made of elastic rubber material, thereby wrapping the outer wall of the second contact ball 45 to prevent the second contact ball 45 from being oxidized by evaporation of oxygen and moisture.

[0047] like Figure 8 As shown, the sleeve device 300 also includes: a sleeve rotating column 306 slidably installed inside the sleeve limiting column 305; a transmission protrusion 307 fixedly installed on the outer wall of the sleeve rotating column 306, and the inner wall of the power rotating bin 301 is provided with a slide groove 310, and the transmission protrusion 307 slides on the inner wall of the slide groove 310.

[0048] It should be noted that, considering the need to seal the outer wall of the second contact ball 45 to isolate oxygen according to the movement state of the first side plate 103 and the side isolation plate 108, the interior of the power rotary chamber 301 is provided with a sleeved rotating column 306, a transmission protrusion 307 and a sleeved lifting rod 308, so that when the first side plate 103 and the side isolation plate 108 are fully opened or fully closed, the bottom of the first side plate 103 is just engaged with the second contact ball 45, and is in a state as shown in FIG. Figure 8 In the state, the sleeve lifting rod 308 rises from the bottom of the power rotating warehouse 301 to the top, and can rotate two circles, and the top of the sleeve rotating column 306 is in contact with the top of the power rotating warehouse 301, and the sleeve rotating column 306 slides inside the sleeve limiting column 305. During the rising process of the sleeve rotating column 306, it is limited by the transmission protrusion 307 and the slide groove 310, so that it automatically rotates when rising, and the effect of lifting and lowering driving the rubber sleeve 303 to rotate can be achieved.

[0049] like Figures 8 to 9 As shown, the sleeve device 300 also includes: a bottom transmission plate 311 rotatably mounted on the top of the sleeve rotating column 306; a first spring 309 fixedly mounted on the top of the bottom transmission plate 311; a sleeve lifting rod 308 fixedly mounted on the top of the bottom transmission plate 311, and a lifting adjustment plate 304 is fixedly mounted on the top of the sleeve lifting rod 308.

[0050] It should be noted that the bottom transmission plate 311 prevents the sleeve rotating column 306 from driving the sleeve lifting rod 308 to rotate when it rises, and the first spring 309 can be in a normal state, the sleeve rotating column 306 and the bottom transmission plate 311 are at the bottom end of the power rotating chamber 301, preventing the transmission protrusion 307 on the outer wall of the sleeve rotating column 306 from getting stuck in the middle position of the power rotating chamber 301, and the lifting adjustment plate 304 can facilitate lifting the sleeve rotating column 306 during movement.

[0051] like Figures 7 to 9 As shown, a transmission device 200 is slidably installed inside the side isolation plate 108, and the transmission device 200 includes: a first transmission slider 201 slidably installed inside the side isolation plate 108; a first lifting block 202 fixedly installed at the end of the first transmission slider 201, the first lifting block 202 slides on the top of the third transmission plate 205, and the first lifting block 202 is used to lift the lifting adjustment plate 304 when moving.

[0052] It should be noted that during the opening and closing of the side isolation plate 108 and the first side plate 103, the first lifting block 202 can be driven to move by the telescopic rod, and a groove with the width of the sleeve lifting rod 308 is set at the center of the first lifting block 202. The movement of the first lifting block 202 can lift the lifting adjustment plate 304, thereby driving the sleeve 302 to rotate during the movement, thereby achieving the effect of isolating oxygen and sealing the second contact ball 45.

[0053] like Figure 8 As shown, the transmission device 200 also includes: a fourth fixed block 206 fixedly mounted on the side wall of the first side plate 103; a second telescopic rod 204 rotatably mounted inside the fourth fixed block 206; a first transmission rod 203 rotatably mounted on the bottom end of the first transmission slider 201, and the bottom end of the first transmission rod 203 is rotatably mounted on the top end of the second telescopic rod 204.

[0054] It should be noted that, considering that the first side plate 103 and the side isolation plate 108 are opened and sealed, the first lifting block 202 can be driven to move. Therefore, a fourth fixed block 206 and a second telescopic rod 204 are provided on the inner wall of the first side plate 103, and a first transmission rod 203 is provided at the bottom end of the first transmission slider 201. Therefore, when the first side plate 103 and the side isolation plate 108 are fully opened, the first transmission slider 201 is lifted up to move in a direction close to the lifting adjustment plate 304, thereby lifting the lifting adjustment plate 304. When the first side plate 103 and the side isolation plate 108 form a sealed cavity, the fourth fixed block 206 and the third transmission plate 205 and the second telescopic rod 204 drive the first transmission slider 201 to move in a direction away from the lifting adjustment plate 304, thereby driving the rotation effect of the sleeve 302.

[0055] like Figure 6 As shown, a torsion spring is provided at the connection portion between the rotating rod 104 and the isolation side plate 106 , and the rotating rod 104 and the isolation side plate 106 are in a vertical state when no external force is applied.
