Title
(EN) TRANSFORMER COOLING SYSTEM AND TRANSFORMER INSTALLATION
(FR) SYSTÈME DE REFROIDISSEMENT DE TRANSFORMATEUR ET INSTALLATION DE TRANSFORMATEUR
Abstract
(EN)
A transformer cooling system (100) is described. The transformer cooling system (100) includes a dry transformer (1) and a housing (50) for the dry transformer. The dry transformer includes a core (10) including a leg (11). Additionally, the dry transformer includes a winding body (14) arranged around the leg (11). Further, a cooling channel (25) extending in a direction of a longitudinal axis of the winding body (14) is provided. Additionally, the transformer cooling system (100) includes a heat exchanger (60) adapted to dissipate heat from the housing (50). Further, the transformer cooling system (100) includes a flow generating device (30) arranged in the housing (50) for providing a cooling flow in the cooling channel (25). The flow generating device (30) is connected to the heat exchanger (60).

La présente invention concerne un système de refroidissement de transformateur (100). Le système de refroidissement de transformateur (100) comprend un transformateur sec (1) et un boîtier (50) pour le transformateur sec. Le transformateur sec comprend un noyau (10) comprenant une patte (11). De plus, le transformateur sec comprend un corps d'enroulement (14) disposé autour de la patte (11). En outre, un canal de refroidissement (25) s'étend dans une direction d'un axe longitudinal du corps d'enroulement (14). De plus, le système de refroidissement de transformateur (100) comprend un échangeur de chaleur (60) conçu pour dissiper la chaleur provenant du boîtier (50). En outre, le système de refroidissement de transformateur (100) comprend un dispositif de génération de flux (30) agencé dans le boîtier (50) pour fournir un flux de refroidissement dans le canal de refroidissement (25). Le dispositif de génération d'écoulement (30) est relié à l'échangeur de chaleur (60).
