A portable high-voltage test instrument (1) comprises an electronic unit (24) having means for producing a test voltage located in the kV range, a control area (3) cooperating with the electronic unit (24), at least one terminal (4, 5) for the component or cable to be tested and for an external voltage supply, a housing (2) for permanently accommodating the electronic unit (24) and a cooling system, disposed inside the housing (2), for cooling the electronic unit (24), the cooling system comprising an air-cooled assembly having an air inlet (13) and an air outlet (14). This housing (2) is provided with a lid part (7) that can be moved between an open and a closed position, such that all terminals (4, 5), the control area (3) and the air inlet (13) and air outlet (14) are covered in closed position thereof, whereas all terminals (4, 5), the control area (3) and the air inlet (13) and air outlet (14) are unobstructed in open position thereof.

L'invention concerne un appareil de test haute tension mobile (1) qui comprend une électronique (24) munie de moyens pour la fourniture d'une tension d'essai se situant dans la plage des kV, une zone de commande (3) interagissant avec l'électronique (24), au moins une connexion (4, 5) pour le composant ou le câble à tester et pour une alimentation en courant externe, un boîtier (2) pour le logement durable de l'électronique (24), ainsi qu'un système de refroidissement placé à l'intérieur du boîtier (2), servant à refroidir l'électronique (24) et comprenant un refroidissement par air pourvu d'une amenée d'air (13) et d'une sortie d'air (14). Selon l'invention, le boîtier (2) comprend un élément couvercle (7) qui peut être déplacé entre une position ouverte et une position fermée et qui, dans sa position fermée, sert à recouvrir toutes les connexions (4, 5), la zone de commande (3), ainsi que l'amenée d'air (13) et la sortie d'air (14). Dans sa position ouverte, l'élément couvercle découvre toutes les connexions (4, 5), la zone de commande (3), ainsi que l'amenée d'air (13) et la sortie d'air (14).
