Sept. 1, 1931. E. HAEF ELY- ELECTRICAL CONDENSER Fiied May .10. 1929 I'll-ll'l ll m mmm E 5 E w I //v vE/v 7'0 Patented Sept. 1, 1931 UNITED STATES.
PATENT OFFlfiE EMIL HAEFELY, OF BASEL, SWITZERLAND This invention relates to electrical condensers comprising a number of condenser units arranged in series and mounted in a frame. Hitherto, in multiple condensers of this kind the connecting leads or conductors embedded in the individual condenser units were individually soldered to conductor wires secured to the frame. This method of mounting however exhibits the disadvantage that when replacing a damaged unit the soldered connection must in the first place be broken. In other arrangements, the condenser units are screw fastened between conducting carriers so that their removal or exchange may also be harmful.
These disadvantages are obviated in accordance with the present invention by the ,fact that the frame bars or rails of the condenser, upon Which-the condenser units are slidden by means of circuit connecting heads, are arranged so as to serve at thesame time as carriers and bus-bars for the current so that the current can be conducted directly over said rails without special connectors,
while the rails allow of easy removal of the units along them.
Soldering operations or the like are thus obviated, the units being simply slidden along current conveying rails with which they are so directly in electrical contact.
In a particularly suitable construction these rails or bus-bars themselves constitute the cross struts bf the frame of the condenser, whereby a considerable saving in material and weight is effected.
The circuit connecting heads of the condenser units consist advantageously of hollow sleeves which, beside their current conveying property, allow also internal cooling through to the core of the units, by means of oil for example, when the whole condenser is immersed in an insulating oil bath,
With a condenser in which the units are mounted in said manner a damaged condenser unit can readily beremoved from the frame and without any soldering being necessary, be replaced by a fresh unit. Further, the condenser units are by their metallic connecting heads directly in electrical contact with the carrying and current conveying CONDENSER 362,055, and in Germany June 16, 1928.
rails, so that there is no intermediate connecting member between the units and the rails or bus-bars in so far as said heads belong to the units themselves.
The invention will now be described, by
way of example, with reference to the ac-' companying drawings, in which Figure 1 illustrates a constructional embodiment of the invention partly in side elevation and partly in longitudinal section;
Figure 2 is a partial front elevation thereof;
Figure 3 is a perspective view of the complete condenser arrangement.
In the constructional embodiment illustrated in the drawings each of the condenser units 7 (Figure 3) consists of spiral paper webs 3 wound on an insulating core 2, between which there are simultaneously wound up two metallic webs or foils r, 4', so that the two foils 4%, l which constitute the armaturs of the condenser, are separated from each other by insulating material (paper) and have one edge in one of them projecting on one front side and the opposite edge in the other projecting on the other front side of the condenser beyond the paper webs 3 as shown in Figure 1 at the right and left hand of the condenser unit -Within the winding thus obtained there are inserted one or more pairs of thin connecting strips 5. While the same were individually soldered to conducting wires secured to the frame, according to the present invention they are conducted to metallic heads 8, which consist ot hollow sleeves and are adapted to clamp the end or ends 6 of the strips 5. These metallic heads 8 are fastened by means of hollow bushings 9 within the insulating core 2 and carry two metal discs 10 for clamping fast the ends 6 of the strips 5 being inserted between them. Owing to the channel 9 in the heads 8, together with the bore of the central core 2, a good cooling of the condenser units from the inside is insured, especially when the condenser is immersed in an oilbath.
In the constructional embodiment illustrated in Figures 1 and 2 the connecting heads 8 of each unit 7 have rectangular transverse slots ll therein by means of which the i constitute at the same time the cross struts of the condenser frame and are secured to metallic rods 15, 15", 15, 15, which also belong to the condenser frame and the ends of which are attached to beams 16 of insu-' lating material.
In this manner the bus-bars 12 arranged in vertical planes above one another are in direct electrical connection with one another, while the individual frame works constituted thereby are insulated from one another by the beams 16. In the three-phase condenser illustrated by way of example in Fig-v ure 3, four such frame works are provided,
the first and fourth of which are electrically connected together by the bridge piecel? and by means of'the terminal tag It are also adapted to be connected to the first phase of the electrical net-work; the two vertical pairs of rods of these two frame works aredesignated by 15. The frame work constituted by the vertical pair of rods 15 and the bus-bars 12 connected thereto is adapted to be connected by means of the terminal tag I) to the second phase of the net-work, while the rods 15 together with the respective busbars are adapted to be connected by means of the terminal tag 0 with the third phase of the net-work.
In this manner there is associated a row of condenser units 7 to each phase of the network.
The bus-bars 12 and the slots 11 in which they are adapted to engage may be of any desired profile: for instance they may also be swallow-tailed, wedge-shaped, of conical or circular form and so on. p
The form, construction and arrangement of each condenser unit may be varied as desired without exceeding the scope of the invention. Advanta eously the units are immersedin a liquid dielectric such as oil.
