[0002] With the large-scale construction of ultra-high voltage direct current (UHVDC) transmission networks, the power grid's transmission capacity has been significantly improved, and its coverage area has been continuously expanded. However, due to the high voltage levels, large tower heights, and long corridors of UHVDC transmission lines, this development has also increased the risk of natural disasters affecting the transmission line corridors. Currently, lightning strikes have become the leading cause of transmission line tripping. The transient overvoltages generated by lightning strikes can reach several times the normal voltage, easily breaking through the line insulation protection system and causing accidents such as line breaks, flashover of test objects, and surge arrester explosions.

[0045] With reference to Figure 1 , the present embodiment provides a dual-mode multi-fold lightning generating device, which comprises a charging module of a charging transformer T and a rectifier silicon stack VD connected in series with the charging transformer, and further comprises:

[0048] But need to explain, when the pulse generation module number is one, refer to Figure 2 The single pulse generation module of the bimodal multiple lightning generation device shown is one, and the charging resistance R is one. The structure described above can constitute a pulse generation module.

[0049] When the number of pulse generation modules is multiple, the bimodal multiple lightning generation device can increase the pulse amplitude by increasing the number of vertical pulse generation modules, and increase the pulse number by increasing the number of horizontally stacked pulse generation modules, to generate multiple lightning.

[0050] Among them, the two sides of the upper charging capacitor are connected with the lower ignition sphere gap and the charging resistor respectively. The impulse voltage / impulse current generated by the upper pulse generation module is superimposed on the lower level, that is Figure 1 The connection relationship shown.

[0051] In addition, it is worth noting here that in the multi-stage pulse generation module, the series combination of the ignition sphere gap and the charging capacitor C needs to be connected with a charging resistor R on both sides, the purpose is to maintain the voltage after the charging capacitor is broken down.

[0058] S4, when charging is complete, a single lightning strike occurs, igniting the ball gap. During discharge, the potential at the upper end of the charging capacitor C instantaneously changes from... When it drops to zero, the lower potential also drops rapidly. Because of the charging resistor R, the potential at the upper end of the charging capacitor C is... The moment the ball gap was breached, it remained in the position. If there are multi-stage pulse generation modules, the ignition ball gap of the later stage... The voltage that needs to be withstood has been changed from the original Become And it is broken down, and so on, with N-level pulse generation modules, then the amplitude is The impulse voltage affects the wave tail resistance. Wavefront resistance Discharge is applied to the test sample, generating an impulse voltage amplitude of [value missing] across the test sample. or The first lightning strike.

[0059] S5, if set to multiple lightning strikes, then set the interval t between lightning strikes. After time t, the pulse generation module generates another impulse voltage amplitude on the test object. or The second lightning strike.

[0060] Additionally, it is worth noting that Figure 1 and Figure 2R0 in the figure is a protective resistor that serves to protect the circuit. It is only shown in the figure for illustration and is not intended to limit the scope of this embodiment.

[0061] In addition, taking current surge as an example, the working process and principle of this device are as follows:

[0062] S1, When a voltage surge is required on the test sample, adjust the tail resistor in the mode conversion module. and wavefront resistance Sizes up to achieve standard lightning impulse voltage current;

[0063] S2, switch ,switch and switch Closing, opening and closing and switch Disconnect to switch the mode to the current impulse mode;

[0064] S3, Adjust ignition ball gap The distance, so that its discharge voltage is set to If there are multiple pulse generation modules, the voltage of the fireball gap at the next stage is at... Between, according to voltage Set the appropriate charging / discharging time based on the voltage; set a longer charging / discharging time for higher voltage and a shorter charging / discharging time for lower voltage.

[0065] S4, when charging is complete and a trigger command is received, ignite the ball gap. During discharge, the potential at the upper end of the charging capacitor C instantaneously changes from... When it drops to zero, the lower potential also drops rapidly. Because of the charging resistor R, the potential at the upper end of the charging capacitor C is... The moment the ball gap was breached, it remained in the position. If there are multi-stage pulse generation modules, the ignition ball gap of the later stage... The voltage that needs to be withstood has been changed from the original Become And it is broken down, and so on, with N-level pulse generation modules, then the generated amplitude is The impulse voltage affects the modulation inductor. Charging is performed on the tuning resistor. Discharge is applied to the test sample, generating an impulse current with an amplitude of [value missing] across the test sample. or The first lightning strike.

[0066] S5, if set to multiple lightning strikes, then set the interval t between lightning strikes. After time t, the pulse generation module generates another impulse current on the test object with an amplitude of [value missing]. or The second lightning strike.

[0067] Additionally, it is worth noting that Figure 1 and Figure 2 R0 in the figure is a protective resistor that serves to protect the circuit. It is only shown in the figure for illustration and is not intended to limit the scope of this embodiment.

[0068] Furthermore, and optionally, different impact methods are used for different types of test objects. Specifically, the test objects include capacitors under test. and / or the resistor to be measured ,in:

[0069] capacitor under test Voltage surge is employed;

[0070] resistance to be tested Current surge is used.

[0071] That is, when the test item only includes capacitance When this happens, the mode conversion module switch will be switched to voltage surge mode for voltage surge testing;

[0072] When the test sample only includes resistance When the voltage surge occurs, the mode conversion module switch is switched to current surge mode for voltage surge testing.

[0073] When the test sample includes capacitance and resistance In this case, at least two pulse generation modules need to be configured. One pulse generation module switches the mode conversion module to voltage impulse mode for voltage impulse testing, and the other pulse generation module switches the mode conversion module to current impulse mode for voltage impulse testing.

[0074] In the technical solution provided in this embodiment, single or multiple lightning strikes are achieved through superimposed pulse generation modules, and convenient switching between voltage and current surges is achieved through a mode conversion module. This enables short-duration, multiple high-pulse lightning strike simulations, thereby meeting the requirements for testing the insulation performance of high-voltage equipment installed on ultra-high-voltage transmission lines.
