XLPE中压电缆水树老化试验装置
Abstract:
(EN)
Disclosed is an aging test device of an XLPE medium voltage cable water tree, which comprises a plurality of ageing test units which are in parallel connection. Each aging test unit comprises an insulation base and a test glass arranged on the insulation base, a cavity for accommodating saline solution being formed in the test glass, an insulation cover being arranged on a glass opening, and a conductive electrode being installed on the insulation cover. An insulation gasket, a test sample, a base electrode and a conductor are sequentially arranged on the insulation base from top to bottom, a through hole is formed in the middle of the insulation base, the upper portion of the through hole has a large diameter to form a groove, the base electrode is arranged in the groove, the upper surface of the base electrode is aligned to the upper surface of the insulation base, and the conductor is connected to the base electrode and is grounded. The periphery of the upper portion of the insulation base extends upwards to form a side wall, the lower portion of the test glass is in threaded connection with the side wall, and the insulation gasket is used for sealing space between a glass bottom opening and the test sample from the periphery. The device is simple in structure, convenient to use and short in required aging test time.
(FR)
La présente invention concerne un dispositif d'essai de vieillissement d'un arbre d'eau dans un câble à moyenne tension et isolation XLPE, qui comprend une pluralité d'unités d'essai de vieillissement qui sont connectées en parallèle. Chaque unité d'essai de vieillissement comprend une base isolante et un verre pour essai agencé sur la base isolante, une cavité permettant d'accueillir une solution saline étant formée dans le verre pour essai, un couvercle isolant étant situé sur une ouverture du verre, et une électrode conductrice étant installée sur le couvercle isolant. Un joint isolant, un échantillon pour essai, une électrode de base et un conducteur sont agencés séquentiellement sur la base isolante de haut en bas, un trou traversant est formé au milieu de la base isolante, la partie supérieure du trou traversant possède un grand diamètre pour former une rainure, l'électrode de base est agencée dans la rainure, la surface supérieure de l'électrode de base est alignée sur la surface supérieure de la base isolante, et le conducteur est connecté à l'électrode de base et est mis à la terre. La périphérie de la partie supérieure de la base isolante s'étend vers le haut pour former une paroi latérale, la partie inférieure du verre pour essai est en connexion filetée avec la paroi latérale, et le joint isolant est utilisé pour fermer hermétiquement l'espace entre une ouverture inférieure du verre et l'échantillon pour essai depuis la périphérie. Le dispositif est de structure simple, pratique à utiliser et sa durée d'essai de vieillissement nécessaire est courte.
