Claims priority, application Germany Jan. 23, 1956 3 Claims. (Cl. 317-234) This invention relates to a high-tension barrier-layer rectification unit for inserting in the high-tension part of an X-ray apparatus in place of the rectifying valves. Such a unit comprises severel rectifier columns each consisting of a round porcelain tube, in which the quadratic rectifier elements are stacked immediately on top of one another in the longitudinal direction of the tube in a quadratic bore. Several such tubes are placed with their longitudinal axes next to one another and with each end fitted in a socket they are combined together to form the high-tension barrier-layer rectification unit. The rectifier columns placed next to each other are electrically connected in series with one another so that the opposite ends of the first and second columns of the unitlocated on the same side of the unit-and the other ends of the second and third columns, and the opposite ends of the third and fourth columns of the unit, etc. are connected to each other.
With this arrangement, double the inverse voltage of one column lies in the inverse phase between the unconnected ends of neighbouring columns. For this reason a considerable safety distance must be left between the porcelain tubes.
According to the invention, the rectifier columns, which are placed with their longitudinal axes next to one another, should be so connected in series with one another that the opposite ends of the columnslocated on the same side of the unit--are electrically connected to the other ends of the columns next to one another.
Other objects of our invention will become apparent in view of the following description taken in connection with the drawings.
In the drawings:
Fig. 1 schematically represents the method of series connection of rectifier columns for three columns accordto this invention;
Fig. 2 illustrates the construction of a high-tension rectification unit according to the invention;
Fig. 3 illustrates an arrangement of containers, spaced apart for clearness, showing the contact strips;
Fig. 4 illustrates another arrangement of connection leads for an arrangement of containers;
Fig. 5 illustrates a construction unit, partly in crosssection, suitable for the lead arrangement according to our invention;
Fig. 6 is a side view of a plurality of containers operatively connected by the lead arrangement according to our invention; and
Fig. 7 is an exploded view illustrating the container unit of our invention.
Referring to Fig. 1, there is schematically illustrated the method of series connection of rectifier columns for three columns 1, 2 and 3 according to this invention. Since the opposite ends of the successive rectifier columns are electrically connected with each other, the electrical potential across opposite points of successive rectifier containers does not exceed the inverse voltage of one rectifier column. In this way, it is possible to bring the rectifier atent" C 2,962,640 Patented Nov. 29, 1960 columns closer to one another with-out the danger of electric spark-over, so that the dimensions of the hightension unit are reduced.
Fig. 2 shows the construction of a high-tension rectification unit according to the invention with three pressed material containers 4, 5, 6 with external and internal quadratic cross-section. The stacks of quadratic rectifier elements 7 which are only partially indicated in the containers 4, 5, 6 are sealed off by contact bodies 11-16 and held in contact under pressure from the compression springs 8, 9, 10 so that good contact between the individual elements 7 is ensured. Contact strips 17 and 18 are arranged between the opposing side walls of the containers 4, 5, 6, which can be located between two insulating plates each 19, 20 and 21, 22 shown by dotdash lines. The contact springs 2326 effect good contact between the contact bodies 11-16 and the contact strips 17, 18. The contact bodies 11 and 16 are provided with protruding connection contacts 27, 28.
The insulating. plate pairs 19, 20, and :21, 22 between the containers 4, S, 6 can be replaced, each pair by one insulating plate such as 29, 30, if the contact strips 17, 18as shown in Fig. 3 wherein the containers are shown spaced farther apart for the sake of clearn.essare passed as far as the longitudinal centre of the rectifier columns on one side of the insulating plate, through the holes 31, 32 of the insulating plates and then along the other side of'the insulating plate. Inthis case the contact strips along the rectifier columns of the two adjacent containers are spatially so arranged that they have the greatest distance from those rectifier elements of the two adjacent containers with respect to which they assume the greatest potential difference in operation.
Another arrangement of the connection leads for the containers 4, 5, 6, which is even better with respect to the potentials, is shown in Fig. 4, wherein the connection leads are not situated between and parallel to the opposing walls of the containers, but are located outside this interspace, and the opposite ends of adjacent columns are connected with each other in a straight line. Most suitable for this connection are nonflexible wires 33, which are equally spaced from each other and arranged so that at no spot a maximum field strength can occur.
A constructional unit which is specially suitable for the lead arrangement according to the invention is shown in a cross-sectional view in Fig. 5 and in side View in Fig. 6. According to Fig. 7, the element containers consist of two U-rails, 34, 35, which after the insertion of the rectifier elements 7 and insertion of a spring 8, are held together at their opposite ends by means of hollow rivets 38, 39, with the aid of metal blocks 36, 3'7, longitudinal slots remaining in this manner unobstructed. The required stability of the containers is obtained by means of an insulating plate 40 made of plastic material, onto which the containers are fastened at a short distance from plate 40, with the aid of hollow rivets 41, 42, which are passed through the hollow rivets 38, 39. The containers are also spaced from each other, so that the cooling me dium has free access to the rectifier eliements through the longitudinal slots. The columns of rectifier elements are electrically connected by non-flexible Wires 33, the ends of which are inserted into the hollow rivets 4t, 42, and are soldered there at 43, 44. In order to suppress the formation of leakage currents on the surface of the plate, the wires do not immediately rest against the plate 40, and the plate 40 is provided with slot-shaped cut-outs 45 on the lower and upper side between the lead holes.
Changes may be made within the scope and spirit of the appended claims.
