Description

Description: FIELD OF THE INVENTION The present invention provides at least one discrete circuit stage having a columnar structure, the discrete circuit stage comprising at least a shock capacitor, a spark gap, and a desired charging characteristic. And these characteristic-determining components, which have the necessary resistance to obtain the shock waveform, are mounted on a vertical wall member in a partially easily replaceable manner by a retaining member mounted on the wall member. The present invention relates to a Marx circuit type shock voltage generator.

2. Description of the Related Art Such an impulse voltage generator is known from German Patent Application Publication No. 1199395. This impulse voltage generator has a columnar structure, and for that reason, each single circuit stage is composed of a tubular member made of an insulating material, and circuit elements such as a resistor, a spark gap, and an impact capacitor are mounted therein. . And collecting a plurality of tubular members and circuit elements,
A multi-stage impulse voltage generator is configured. The wall surface member of the tubular member has a stepped area at its lower end portion that increases toward the outside, and has a pedestal portion formed therein to accommodate the upper end portion of the lower circuit step. In this case, the inner wall surfaces of the upper and lower circuit stages are one flat surface without a break. Then, two rectangular carriers are provided on the inner wall of each tubular member, by which the electrical elements are brought into contact and attached.

When changing the circuit of the impulse voltage generator, an opening is provided in the tubular member, and the discharge resistance is exchanged through this opening.
The other elements are practically non-exchangeable. In order for these elements also to be replaceable, the tubular member must be provided with another opening.

Further, according to German Patent Application Publication No. 1223946, it is known to form a high voltage circuit from individual components that are similarly constructed, stacked vertically at the ends, and combined at right angles. is there. by this,
Arbitrary circuit configurations are possible.

Further, according to German Patent Application Publication No. 1488970, in order to attach each component except the impact capacitor to each of the individual components of the impact voltage generator including the tubular member, one end of each component is used as a holding bolt. It is known to fix and position along the outer wall. This configuration allows the replacement of elements outside the tubular member. However, since the arrangement of the elements is offset to one side, a large base area is required when stacking the individual circuit stages vertically. Therefore, the columnar structure cannot be tilted.

SUMMARY OF THE INVENTION Therefore, an object of the present invention is to provide an impact voltage generator of the type described at the beginning that can be easily manufactured from inexpensive individual components, and is configured when controlling or changing the impact voltage generator circuit. The element should be easily replaceable and the base area should be as small as possible.

Means for Solving the Problems According to the present invention, this problem is solved by the following configuration.

That is, the wall member of the impulse voltage generator according to the present invention is composed of a plurality of insulating material plates arranged in parallel to the column axis, and the insulating material plate has a cross section of the wall member having an equilateral triangle or polygon. To form a square or arcuate connecting member, the connecting members being located at the corners of the triangle or polygon respectively, at both ends of the insulating material plate, the insulating material plate. Is provided with four holding members, each of which is configured as a bolt, and the contact portion of the electrical component is located at the outer end of the holding member located outside the insulating material plate. For mounting on a part, the holding member has at least one pedestal part provided in the center of the recess, the electrical component being outside on the periphery of a triangle or polygon, Retention Material is arranged parallel to the plane of the insulating material plate and at a distance from the insulating material plate and is in contact with each other, and the groove portion of the contact portion at the end portion of the component is convex on the pedestal portion of the holding member. By the holding element that engages with the portion and protrudes outward from the coupling member, another electrical component is arranged and contact-connected by the concavo-convex coupling parallel to the column axis, and at the lowest circuit stage, A charging device consisting of a rectifier and a first charging resistor is provided, which charging device is solved by having a supply voltage terminal.

Advantages of the Invention The insulating material plate and the bending member or the connecting member used in the impulse voltage generator of the present invention are low-cost components, and the cross-sectional area of the columnar structure can be reduced. Since the wall member of the impact voltage generator is flat, each component can be mounted in the immediate vicinity of the wall and can be arranged on the entire peripheral surface of the wall. As a result, the tilting moment is significantly smaller than in known devices and the required base area can be reduced to a minimum.

The impulse voltage generator disclosed in DE 518 228 certainly has the shape of an equilateral triangle in plan and plan view. However, in this generator, the pin insulator is provided only at each vertex of the triangle, and there is no wall member.

Claims 2 to 18 show advantageous embodiments of the impulse voltage generator according to the invention.

Next, the present invention will be described in detail based on the embodiments shown in the drawings.

Embodiment FIG. 1 is a basic circuit diagram of an impulse voltage generator according to the present invention.

Since this circuit diagram itself is known, its function will not be described in detail. This circuit has the following components.

The charging device LE configured as a transformer has two rectifiers
It is housed in the input stage along with GL and the first charging resistor RL. Each of the other circuit stages of the multi-stage shock voltage generator has a discharge resistor RE, a shock capacitor CS, and a spark gap F.
S, charging resistor RL, braking resistor RD and load capacitor CB are provided. The final stage shown at the top of the figure has the final braking resistance RD.

The multi-stage impulse voltage generator according to the present invention comprises one or a plurality of circuit stages 1 shown in FIG. The wall member 2 of this circuit stage 1 is formed by a plurality of flat plates 3 of insulating material, which plates 3 preferably have the same size. Three or more such plates 3 of insulating material are provided in their upper third region 4 and their lower third region 5 (see FIG. 2) or in the upper half. Section and the lower half section are connected to each other via a connecting member 6 having a rectangular shape or an arc shape, and these insulating material plates form an equilateral triangle or an equilateral polygon as shown in the plan view of FIG. Has been done. In this way, a columnar member having a very small base area and being very stable can be obtained. A plurality of such columnar members are assembled to form one columnar structure.

At least two holding members 7 are attached to both sides of one insulating material plate 3 so as to project outward. These holding members 7 are preferably inserted into the insulating material plate 3 and are used for screwing the connecting members 6 onto the insulating material plate 3. The holding member 7 is, for example, an insulating material plate 3
Are equally spaced from the edge of the. That is, it is located on a plane extending perpendicularly to the column axis 8. The distance A between the holding members 7 is preferably half the height of the insulating material plate 3 or half the effective height H of the insulating material plate 3. Such an arrangement is shown in the side view of the wall member of FIG. 5 depicting the side edge 9 of the insulating material plate 3.

As shown in FIG. 4, the upper and lower ends 10 and 11 of the insulating material plate 3 are paired in parallel with each other for the purpose of stacking the circuit stages 1 of the impact generator on top of each other and fixing their positions. Formed are longitudinal joints 12, 13 of the same shape. These longitudinal seam portions 12, 13 are butted against one another and locked when stacking the circuit breaks 1.
In that case, the outer wall surface 14 and the inner wall surface 15 of each insulating material plate 3 advantageously form a plane. In this way, the outer wall surface 14 and the inner wall surface 15 of the columnar structure 16 are completely flat surfaces without any steps (see also FIG. 5).

Here, the effective height H of the insulating material plate and the distance A between the holding members will be described.

As shown in FIG. 5, the central portion of the upper longitudinal seam portion 12 of one plate of insulating material and the central portion of the lower longitudinal seam portion 13 of this plate of insulating material (i.e. The distance between the upper part of the insulating material plate and the central part of the longitudinal seam portion 12 (see the dashed line in FIG. 5) is referred to as the effective height H of the insulating material plate 3. This constitutes the height in calculating the height of the circuit stage 1. As mentioned above, the upper end portion 10 of one insulating material plate 3 has an upper longitudinal seam portion 12
The lower end 11 of the insulating material plate 3 is provided with a lower longitudinal seam portion 13. Since these longitudinal seams are parallel to each other and are configured in pairs with the same shape, when these seams are brought together, the height of one circuit stage depends on the height of the seams. Reduces somewhat to the effective height H. The above-mentioned interval A itself between the two holding members 7 located above and below each other is irrelevant to the above-mentioned effective height H or the total height of the insulating material plate 3, but, for example, A = 1 / n · H. Is preferable, and in this case, it is preferable to select 1 or 2 or 3 for n. This is because it gives a uniform structure. If n = 1, the distance A is equal to H. In the case of n = 2, the distance A is equal to half the height of H, that is to say two circuits can be mounted one above the other for each height of one insulating material plate. Generally, n = 2 is sufficient and suitable.

Next, with reference to FIGS. 6 to 8, individual embodiments of the coupling member 6, the holding member 7 and the component 22 and modified examples thereof will be described in detail.

As shown in FIG. 2, the coupling member 6 is located at the corner portion of the triangular columnar structure or the polygonal columnar structure which constitutes each circuit stage 1 of the impulse voltage generator. In this case, the holding member 7 is configured as a bolt, and at the outer end 17 of the holding member outside the insulating material plate 3, at least one pedestal 18 is provided.
Is provided. The pedestal portion 18 has a recess 19 formed in the shape of a ring-shaped groove, for example. The contact portion 21 of the component 22 of the impulse voltage generator, such as a charging resistor, a discharge resistor, a resistance such as a braking resistor, an impact capacitor or a spark gap, is placed on the pedestal 18 with sufficient play 20. be able to. The contact part 21 is preferably arranged at the end of a tubular component 22, for example, in which a ring-shaped groove 23 is engraved. Since the pedestal portion 18 and the contact portion 21 are configured to be locked to each other, the constituent element
22 can be well fixed and connected.

The insulating material plate 3 made of hard paper or transparent synthetic resin (for example, acrylic glass) is detachably connected to the holding member 7 by screws 24a and cap nuts 24b (see FIG. 7).

As shown in FIGS. 6 and 7, the recess 19 is designed, for example, as an intermediate web. In other words, this region is formed by scraping off the bolt material forming the holding member 7 from both sides so that only the recess 19 is left. Then, the bottom portion 25 of the groove 23 of the contact portion 21 is placed on the intermediate web forming the recess 19.

FIG. 8 shows a modified embodiment of the pedestal portion of the holding member 7. Referring to the cross-sectional view of FIG. 8a (ie the cross-sectional view of the intermediate web region) taken along the line C-D of FIG. 7, the embodiment of FIGS. The central web of this region is such that the width of this area is generally
It can be said that it was formed by completely scraping the bolt material from both sides until it became substantially smaller than the width.
However, in the case of the variant of FIG. 8, the cross-section of the region of the intermediate web is not completely shaved on both sides and is configured convexly as shown in this cross-section, that is to say convex. It is configured as part 26. This protrusion 26 is somewhat larger than the groove 23 of the contact portion 21, so that the bottom 25 of the groove rests on the protruding portion of the protrusion 26 forming the intermediate web or spring.

By arranging two coupling members 6 and two holding portions 7 in the vertical direction, all the circuit stages 1 of the impulse voltage generator can be configured as a two-stage unit. In this case, with respect to the two holding members 7 that are diagonally opposed to each other,
A component 22 is provided which is designed as a braking resistor RD (see dashed line in FIG. 2). The component 22 couples two circuit stages of stage 1 or adjacent circuit stages of stage 1 stacked one above the other. Space A between the holding members described above
If a to a are properly selected, the mutual spacing between all the holding members 7 arranged vertically can be made equal (see FIG. 5). In order to fix the components 22 arranged in a diagonal direction, the holding member 7 is installed with a corresponding tilt. Alternatively, an additionally inclined pedestal is provided (see FIG. 8b).

In order to obtain a mechanically stable structure when the height of the columnar structure 16 becomes considerably high, for example, when the impact voltage generator is configured in 6 or 8 stages, as shown in FIG. A hole 27 is provided at the center of the longitudinal joint portions 12 and 13, and a locking pin 27a is inserted therein. The locking pin 27a is fixed in the hole by pressure spring, adhesive, screwing or the like.

In order to vertically arrange the component RL, which is a charging resistor,
A retaining element 7'is provided in the central region 28 of the connecting member 6 (in particular if it is of arcuate construction). This holding element 7'is preferably designed as a contact device. The two components RL are mounted on and in contact with the holding element 7 ', offset from each other by at least the diameter of the terminal 29 (if the terminal is circular) or the cross-sectional length (if non-circular).

9 and 10 show two stages of the charging resistor RL arranged or attached to the holding element 7 ', viewed from two different angles. The holding element 7 ′ is attached to the arcuate connecting member 6 by a screw connection like the holding member 7.
For mounting the charging resistor RL (same for the load capacitor CB), it is advantageous if each holding element 7'has a slit 30 perpendicular to the column axis 8. This slit
30 is used as a guide to terminal 29 of charging resistor RL or load capacitor CB.

When holding the load capacitor CB, it is advantageous if the holding element 7'is molded resin. It is advantageous to provide a holding element 7'made of insulating material between the terminal at ground potential and the highest voltage in the region of the uppermost braking resistor.

At the lowest stage 1 of each circuit stage arranged side by side,
It would be advantageous to house a charging device consisting of a rectifier and a first charging resistor. This stage is also provided with a voltage terminal for the transformer supplying the supply voltage. Then, the height of the columnar structure 16 is increased by one circuit step, but the base area thereof is reduced and the movement performance is also improved. In addition, hollow steps 31 having a height half the height H of one step can be provided at the upper and lower ends of the columnar structure 16 (see FIG. 5). in this case,
The upper hollow stage 31 is provided with a connecting element for the last braking resistance. In this way, the columnar structure 16 can be mounted on the plate-shaped base 32. The base 32 is configured to correspond to the outer peripheral shape of the columnar structure 16 and has at least 3
3, preferably 5 support members 33 (see FIG. 3). The support members 33 are arranged at substantially the same center angle with each other. Further, the support member 33 can be provided with a large number of guide wheels (not shown). The columnar structure 16 is preferably arranged such that the end of the lowest operating stage, which is to be at ground potential, is connected to ground.

As shown in FIG. 8, the auxiliary holding element 34 can also be used to attach the component 22 to the holding member 7. This auxiliary holding element is designed as a siding or bent angle member and is used to ensure contact.

As described above, the shock voltage generator according to the present invention is basically constructed as follows. In other words, depending on the wall member, a polygon that is a triangle or larger in plan view (cross-sectional view),
For example, parallelograms or pentagons are formed.

EFFECTS OF THE INVENTION The impulse voltage generator of the present invention can be easily manufactured from inexpensive individual elements, the circuit elements can be easily replaced, and the base area can be made as small as possible.
