Title (EN) BUSHING FOR TRANSFORMER
(FR) TRAVERSÉE POUR TRANSFORMATEUR
(KO) 변압기용 부싱
Abstract: front page image
(EN)The present invention relates to a bushing for a transformer and, more particularly, to a bushing for a transformer, which can prevent the occurrence of a gap caused by different thermal expansion coefficients between an insulator constituting the bushing and a stud provided in the insulator when a thermal expansion occurs at a temperature rise of the transformer, thereby stably preventing a leakage of an insulation oil. In order to achieve the objective, the present invention comprises: an insulator installed in a transformer; a terminal provided in an upper portion of the insulator; and a stud provided in a first through-hole formed inside the insulator and connected to the terminal on an upper portion thereof, wherein a second connection part coupled to the terminal is formed in an upper portion of the insulator, and a first connection part is formed in a lower portion of the terminal to insert and fix the second connection part.
(FR)La présente invention concerne une traversée pour transformateur et, plus particulièrement, une traversée pour un transformateur, qui peut empêcher l'apparition d'un espacement causé par des différences de coefficients de dilatation thermique entre un isolant constituant la traversée et un montant disposé dans l'isolant lorsqu'une dilatation thermique se produit lors d’une élévation de température du transformateur, de façon à éviter de façon stable une fuite d'huile d'isolation. Afin de réaliser cet objectif, la présente invention comprend : un isolateur installé dans un transformateur ; une borne disposée dans une partie supérieure de l'isolateur ; et un montant disposé dans un premier trou traversant formé à l'intérieur de l'isolateur et connecté à la borne sur une partie supérieure de celui-ci, une deuxième partie de connexion couplée à la borne étant formée dans une partie supérieure de l'isolateur, et une première partie de connexion est formée dans une partie inférieure de la borne pour insérer et fixer la deuxième partie de connexion.
(KO)본 발명은 변압기용 부싱에 관한 것으로서, 더욱 상세하게는 부싱을 구성하는 애자와 애자의 내부에 구비되는 스터드의 열팽창계수가 달라, 변압기의 온도 상승시 열팽창할 경우, 서로 다른 열팽창계수에 의해 갭이 발생하는 것을 방지하여 절연유가 누유되는 것을 안정적으로 방지할 수 있는 변압기용 부싱에 관한 것이다. 상기한 목적을 달성하기 위한 본 발명은 변압기에 설치되는 애자와, 상기 애자의 상부에 구비되는 터미널과, 상기 애자의 내측에 형성되는 제1관통공에 구비되되 상단은 터미널과 연결되는 스터드로 이루어지되, 상기 애자의 상부에는 상기 터미널과 결합되는 제2연결부가 형성되고, 상기 터미널의 하부에는 상기 제2연결부가 삽입 고정되는 제1연결부가 형성되는 것을 특징으로 한다.
