UNITED STATES EMIL PIIFFNER; OE BUDAPEST, KUNGARY.
HIGH-TENSION FUSE.
Application filed m 13, 1924. Serial at. 713,107.
To all whom it may concern:
Be it known that I, EMIL PFLFFNER, a citizen of the Republic of Switzerland, residing at Budapest, Hungary, have invented certain new and useful Improvements 1n High-Tension F uses, of which the followin is a specification.
iligh-tension wire fuses of a small crosssectional area, which are under the influence 1 of a high potential, are the cause of trouble in that owing to the influence of the electric field alterations take place on the surface of the fuse-wire which are displayed in the form of oxidations and corrosions and cause a premature and groundless blowing of the fuse.
It is known to arrange in the fuse multiple spark-gaps in order to improve the extinguishing or quenching efi'ect.
The essential feature of the high-tenslon fuse according to the present invention consists in that the sparking gaps composed of a plurality of nesting electrodes, which are electrically connected with the fuse-wire,
and are of such a shape that a plane perpendicular to the fuse-wire intersects more than one of the electrodes.
Several modes of carrying out the present invention areillustrated by way of ex.- ample on the accompanying sheet of drawin in whichig. 1 shows a. fuse in longitudinal section. ,j
Fig. 2 illustrates the formation of the electric field in the inner space and at the periphery.
Fig. 3 shows a modification. f designates the fuse-wire and e the electrodes which are held apart in the insulat- 40 ing tube ?1' by means of insulating rings 1'. .The electrodes e are under the influence of the same electric potential, as they are electrically connectedb means of the fuse-wire f. Practically all-t e electric lines of force pass out from the outer periphery of the electrodes e, while the inner space a; is protected practically entirely by the electrodes e and is not under the influence of the field, so that the fuse-wire is protected.
lished by In the modification shown in Fig. 3, t-he fuse-wire f passes loosely through, the electrodes and the electric connection is estabconductors k (balls), which are loosely disposed in the electrodes, the con tact beingestablished by the pressure ow- 7 ing tol the weight of these balls.
aim
1. A high-tension bination a fuse-wire and a multiple spark-gap which is electrically con'nectedwith the fusewire, the said multiple spark-gap consisting of a plurality of nestingly arranged electrodes insulated from one another and shaped to shield the fuse-wire and also shaped so. that a plane perpendicular to the fuse-wire intersects the electrodes.
2; A high-tension fuse comprising in combination a fuse-wire, a multiple spark-gap consisting of a plurality of nestingly arranged downwardly taf'pered hollow electrodes each of WlllCll is provided with a hole through which the fuse wire loosely presses, the said electrodes being insulated om one another and shaped to shield the fuse-wire and also shaped so that a plane perpendicular to the fuse-wire intersects more than one of the electrodes, and heavy conductors disposed within the cavity of each electrode which owing to their weight rest against the fuse-wire in order to establish electric connection between the latter more than one of p and the inner wall of the electrode;
