Referring to FIG. 1, the ultra-high voltage pulse generator according to the present invention includes a housing 109, a plurality of capacitors 103, a plurality of resistors 102, a plurality of gap switches 104, and a plurality of covers 107, 108. ).

The housing 109 constitutes the main body of the device and is open tubular on both sides. The plurality of capacitors 103 are arranged in a plurality of columns having a structure of an electrically parallel and parallel circuit inside each other inside the housing 109, and is charged by receiving a voltage from the DC power supply 101 through an input terminal, When the input terminal is shorted, an application of a voltage higher than the charging voltage and a short circuit are sequentially performed to output an ultra high voltage pulse through the output terminal 105. The plurality of resistors 102 are provided on the parallel connection circuit line in the parallel and parallel connection circuit line between the plurality of capacitors 103, respectively, and limit the amount of current input to each capacitor 103. The plurality of gap switches 104 are each provided on a series connection circuit line in a series-parallel connection circuit line between the plurality of capacitors 103, and are open when the capacitors 103 are charged. In the case of outputting an ultra-high voltage pulse through the output terminal 105, each of them maintains a short state. The plurality of covers 107 and 108 are detachably coupled to both opening portions of the housing 109, respectively, and the built-in components are formed by blocking components installed inside the housing 109 together with the housing 109 from the outside. Protect the elements.

Here, such an ultra-high voltage pulse generator is for stably fixing the plurality of capacitors 103, at least one capacitor mounting member 106 having a plurality of mounting grooves for mounting of each capacitor 103. It may be configured to include more.

In addition, the ultra-high voltage pulse generator is for stably fixing the plurality of condenser 103, at least one capacitor supporting member 112 for supporting the plurality of condenser 103 at the side of the condenser 103 at once. It can be configured to include more.

In addition, an o-ring 110 or a gasket may be further installed at a coupling portion of the housing 109 and the covers 107 and 108 of the ultra-high voltage pulse generator to further ensure a sealed state.

Here, the plurality of gap switches 104 may be installed to be connected to the (-) terminal of the next capacitor 103 from the capacitor 103 (+) terminal of the front stage.

In addition, the plurality of capacitors 103 arranged in a plurality of rows may be arranged such that the capacitors 103 arranged in different rows have a zigzag arrangement relationship with each other.

In addition, the gap switch 104a, which is located at the head of the power input terminal, among the plurality of gap switches 104, is automatically shorted in a low voltage state or shortened by a forced trigger signal compared to other switches 104 that follow. It is configured to be.

Here, the capacitor mounting member 106 is subjected to the uneven processing (106a, 106b) to prevent high voltage insulation breakdown between the plurality of capacitor 103 stages and stages and to secure a safety distance.

FIG. 2 is a view showing in more detail the relationship of the internal components of the resistors, capacitors, and switches of FIG. 1, and zigzag the components 102, 103, and 104 in order to shorten the length of the ultra-high voltage pulse generator. Placed.

FIG. 3 is an equivalent circuit diagram illustrating an arrangement relationship of internal components of FIG. 2.

Referring to FIG. 3, the capacitor 103, which is charged from the positive-cathode (±) DC power source 101 via the resistor 102, is connected in series and parallel, and the gap switch is connected to the next terminal of the positive capacitor. However, it is connected to the negative terminal of the capacitor. Therefore, the first stage condenser, the switch, the second stage condenser, the switch in order to be stacked, in order to reduce the length is arranged in a zigzag left / right as shown in FIG.

The gap switch 104 is open during charging. This is a form developed from the basic Marx circuit, and as the applied voltage of the individual capacitors by the series-parallel coupling is reduced to 50%, the device insulation distance can be reduced and consequently the device volume can be reduced. The switch 104a in its starting position is capable of spontaneously shorting at a lower voltage than other switches or with a forced trigger signal.

The uneven structure 106a of FIG. 4 and the uneven structure 106b of FIG. 5 differ in shape. That is, the structure of the unevenness 106a of the upper condenser seating member of the apparatus is different from that of the unevenness 106b of the lower condenser seating member of the apparatus, as shown in FIG. This is because the + terminal is connected to the (-) terminal of the next capacitor, so that the gap switch is arranged in one side on one side and diagonally in the opposite side as shown in FIG. That is, the concave-convex or grooved structure is designed in accordance with the arrangement of the gap switch.
