 phasenhörnerableitern. Es wird an jede Phase ein Horn angeschlossen und diese Hörner werden symmetrisch zueinander gruppiert, also bei   Drciphasenstrom   drei um 1200 gegeneinander versetzte Hörner angeordnet. Zwischen diesen befinden sich Nebenhörner, die an den Sternpunkt der Stromquelle oder an Erde gelegt sind. Es genügen bei Dreiphasenstrom zwei Nebenlörner. Die Nebenhörner können wesentlich kleiner sein, wie die Haupthörner. In Fig. 1 und 2 bedeuten a, b, c die an die drei Phasen angeschlossenen Haupt- 
 EMI1.2 
 in Fig. 1 zum Ausdruck kommt, ganz fehlen. Zweckmässig aber ist es, nicht unter die   Zwt'izahl   der Nebenhörner herunterzugehen. 



   Die   Nebenhörner   können unmittelbar miteinander kurzgeschlossen sein und an den Sterupunkt der Stromquelle oder an eine gemeinsame Erdelektrode gelegt werden. Am besten wird jedes Horn, zum mindesten jedes Nebenhorn für sich verstellbar gemacht. 



   Der Vorteil dieser Anordnung liegt darin, dass man mit einer.   Mindestzahl von   Hörnern eine   sehr wirksame Sterndreiock-Schutzanordnung bekommt,   wie eine solche durch das   österreichische   Patent Nr. 25927 bekannt geworden ist, bei welcher die   Überspannungs-   sicherungen (Funkenstrecke) im Dreieck, die   Vorschaltwiderstände   im Stern geschaltet

 EMI1.1
 phase horn arresters. A horn is connected to each phase and these horns are grouped symmetrically to one another, i.e. three horns offset from one another by 1200 with three-phase current. Between these are secondary horns that are connected to the star point of the power source or to earth. With a three-phase current, two additional holes are sufficient. The minor horns can be much smaller than the main horns. In Fig. 1 and 2, a, b, c denote the main connected to the three phases
 EMI1.2
 in Fig. 1 is expressed, completely absent. However, it is advisable not to go below the number of secondary horns.



   The secondary horns can be short-circuited directly to one another and connected to the steru point of the power source or to a common earth electrode. It is best to make each horn, or at least each secondary horn, individually adjustable.



   The advantage of this arrangement is that you can use a. Minimum number of horns a very effective star-three-dock protection arrangement, as known from the Austrian patent no. 25927, in which the overvoltage protection (spark gap) is connected in a triangle and the series resistors in a star

 so that the case can be stored in or under a uniform protective cover.
