Definitions

  • the filament structure is mechanically and electrically at or near the positive or negative high voltage terminal and potential, and it is essential that the filament power be tied to the high voltage potential accelerating the particle beam.
  • the heater or filament typically operates at low voltage, e.g. 2-10 volts, and at high current, e.g. 5- 30 amperes. Delivery of the heater energy to the filament from the primary power mains requires a step-down transformer which manifests efficient transconductance while providing the requisite potential difference between ground and the very high potential of the filament structure.
  • Fig. 1 is a side view in elevation of a high voltage isolation filament transformer in accordance with the principles of the present invention, with certain portions of the structure broken away to reveal underlying structure.
  • a fiberglass tape 22 is wrapped directly over the primary winding 20.
  • a metal foil tape 23 is wrapped over the fiberglass tape 22 surrounding the primary winding 20. (The ends 24 of the primary winding 20 are extended outwardly from the fiberglass tape 22 and metal tape 23 to a suitable connection to a primary power source, such as the 110 volt AC mains.)

Abstract

Un transformateur d'isolation (10) assure l'isolation d'une haute tension entre un enroulement primaire et un enroulement secondaire. Le transformateur d'isolation comprend une structure de noyau en boucle (12) constitué d'une boucle en spirale d'un matériau en bande ferromagnétique. L'enroulement primaire (20) est enroulé de manière hélicoïdale sensiblement tout autour de la structure en boucle. Un support (30) d'enroulement primaire est prévu pour porter le noyau en boucle et l'enroulement primaire. L'enroulement secondaire (14) est formé à la manière d'un anneau au-dessus et espacé de la structure de noyau en boucle et de l'enroulement primaire. L'enroulement secondaire est placé par rapport à la structure de noyau en boucle de sorte qu'il se trouve dans un premier plan sensiblement perpendiculaire à un second plan comprenant la structure de noyau en boucle. Un support diélectrique solide (42) est prévu pour porter l'enroulement secondaire et le positionner par rapport à la structure à noyau en boucle et à l'enroulement primaire.
