Description
Verfahren zur Verhinderung der Funkenbildung bei Kommutatoren, Kontaktgleichrichtern und ähnlichen elektrischen Gebilden In vielen elektrischen Maschinen, die mit Kommutatoren ausgerüstet sind, oder beispielsweise in mechanischen Gleichrichtern, die mit Kontaktbahnen oder Taumelkörpern arbeiten, kann man auch trotz der Anwendung von allerlei Schaltmitteln nicht eine jede Funkenbildung unterdrücken. Die Folgen sind den Fachleuten bekannt.Procedure to prevent sparking in commutators, contact rectifiers and similar electrical structures in many electrical machines that use commutators are equipped, or, for example, in mechanical rectifiers with contact tracks or wobble bodies can work despite the use of all sorts of switching means do not suppress any spark formation. The consequences are known to those skilled in the art.
Nach der Erfindung wird vorgeschlagen, wenn nicht die ganze Maschine, so doch die Teile, auf welchen sich die Funken bilden, luftdicht abzuschließen und unter Druck zu setzen. Als Druckmedium kann außer Luft auch ein indifferentes Gas, wie Stickstoff, Helium, Cryphon u. dgl., verwendet werden. Auf diese Weise ist es möglich, die Durchschlagsspannung zu erhöhen oder bei Gleichrichtern mit Kontaktbahnen, auf welchen sich ein taumelkörperähnlicher Kontaktkörper abwälzt, die Hubhöhe des Taumelkörpers bei gleicher Durchschlagsspannung zu verringern oder umgekehrt die Durchschlagsspannung bei gleicher Hubhöhe zu erhöhen.According to the invention it is proposed, if not the whole machine, so the parts on which the sparks are formed must be sealed airtight and put under pressure. In addition to air, an inert gas, such as nitrogen, helium, cryphone and the like can be used. That way it is possible to increase the breakdown voltage or, in the case of rectifiers with contact tracks, on which a contact body similar to a wobble body rolls, the lifting height of the To reduce the wobble body with the same breakdown voltage or vice versa Increase the breakdown voltage with the same lifting height.
Wird die ganze Maschine unter Druck gesetzt, so kann dies beispielsweise vermittels einer aus beliebigem Material angefertigten Glocke geschehen, und werden nur Kontaktbahnen oder Kollektoren nach der Erfindung behandelt, so wird man sich durch Iläubenkonstruktionen, die von Fall zu Fall durch den Fachmann entworfen werden, leicht helfen können.If the whole machine is put under pressure, this can be, for example happen by means of a bell made of any material, and will treated only contact tracks or collectors according to the invention, so you will by Canopy constructions designed on a case-by-case basis by a specialist can help easily.
