Electric component in the form of a compact transformer/fluorescent lamp ballast in a kettle-like casing has a liquid cooling mechanism for a coil and a magnetic core.

摘要

A magnetic core (2-5) has a lower yoke (2), two limbs (4,5) and upper yoke (3). One of the limbs has a winding (6,7). A window is formed between the two limbs. A casing (13) has two casing walls (14,15) opposite each other, running parallel to the window of the magnetic core and connected by means of an insulated single-plate stiffening device (8) that has a tensile force and penetrates the window between the two limbs.
