Abstract

La présente invention concerne une unité de génération de haute tension (100) comprenant un boîtier d'unité, une unité de décharge et une section en saillie. La section en saillie est disposée vers le bas à partir de l'unité de décharge et fait saillie depuis le boîtier d'unité sur une étendue supérieure à celle de l'unité de décharge. Un support maintient l'unité de génération de haute tension d'une manière qui permet de la fixer/détacher. Une section de logement de support (130) peut accueillir la fixation du support. Un passage de support, à travers lequel passe le support lorsqu'il est fixé à la section de logement de support (130), est formé dans la section de logement de support (130). Une section d'ouverture (132) au niveau de laquelle le passage de support communique avec l'extérieur est formée dans la section de logement de support (130). La surface de la paroi inférieure du passage de support comprend une surface inférieure de section d'ouverture plane (136) continue à la section d'ouverture (132) et un palier (137) qui s'étend vers le bas par rapport à la hauteur de la surface inférieure de section d'ouverture (136).
