Definitions

  • low voltage particularly refers to a rectified mains voltage, equal to about 250V.
  • Ruhmkorff coil where an induction coil, known also as Ruhmkorff coil, is characterized by a disruptive discharge coil.
  • said housing seat is composed of a coiled channel bored in the thickness of the outer walls of the magnetic core, such to form turns housing the turns of the primary winding.
  • the magnetic core In order to obtain further advantages as regards the constructional perspective and as regards the assembling perspective it is possible to provide the magnetic core to have at least one passage area obtained in the thickness of the magnetic core, intended for the insertion of at least one of the two ends of the primary winding.
  • the magnetic core 2 has at least one passage area obtained in the thickness of the magnetic core 2, intended for the insertion of at least one of the two ends of the primary winding 1.

Claims (7)

  1. Hochspannungstransformator mit mindestens einer um einen Magnetkern (2) gewickelten Primärwicklung (1) und mindestens einer Sekundärwicklung (3), wobei die Enden der Primärwicklung (1) mit einer Niederspannungsgleichstromquelle verbindbar sind, wobei ferner Mittel zum Unterbrechen des Gleichstroms vorgesehen sind, die dazu vorgesehen sind, die Gleichstromversorgung der Primärwicklung (1) periodisch zu unterbrechen, wobei die Primärwicklung (1) zumindest teilweise innerhalb des Außenprofils des Magnetkerns (2) enthalten ist; der Magnetkern (2) zumindest einen in der Dicke der Außenwände des Magnetkerns (2) ausgebildeten Gehäusesitz (21) aufweist, der dazu bestimmt ist, die Primärwicklung (1) und/oder die Sekundärwicklung (3) aufzunehmen, dadurch gekennzeichnet, dass der Gehäusesitz (21) einen gewendelten Kanal aufweist, der in die Dicke der Außenwände des Magnetkerns (2) eingearbeitet ist, so dass Windungen gebildet werden, die die Windungen der Primärwicklung (1) aufnehmen.
  2. Transformator nach Anspruch 1, wobei die Sekundärwicklung (3) zumindest teilweise innerhalb des Außenprofils des Magnetkerns (2) enthalten ist.
  3. Transformator nach Anspruch 1 oder 2, wobei der Magnetkern (2) mindestens zwei an den Stirnseiten des Magnetkerns (2) angeordnete radiale Erweiterungen (23, 24) aufweist.
  4. Transformator nach einem oder mehreren der vorhergehenden Ansprüche, wobei der Magnetkern (2) in zwei miteinander verbindbare Teile unterteilt ist.
  5. Transformator nach einem oder mehreren der vorhergehenden Ansprüche, wobei die Windungen der Primärwicklung (1) um den Magnetkern (2) gewickelt sind, so dass eine gleichmäßige Verteilung entlang des Magnetkerns gewährleistet ist, wobei die Sekundärwicklung (3) an der Primärwicklung angeordnet ist.
  6. Transformator nach einem oder mehreren der vorhergehenden Ansprüche, wobei der Magnetkern (2) mindestens einen Durchgangsbereich aufweist, der in die Dicke des Magnetkerns (2) eingeformt ist und zum Einstecken wenigstens eines der beiden Enden der Primärwicklung (1) eingerichtet ist.
  7. Transformator nach einem oder mehreren der vorhergehenden Ansprüche, wobei die Windungen der Primärwicklung (1) und die Windungen der Sekundärwicklung (3) von einem Mantel aus Isoliermaterial bedeckt sind.
