The present invention relates to a bushing for a transformer that prevents a drop in electrical conductivity by forming a copper rod and a terminal with the same material while the bushing is connected to the transformer housing without leakage.

일반적으로 변압기는 고전압을 저전압으로 변압하여 송배전하기 위한 것으로, 상호 유도를 가지는 다수의 권선코일과 이 권선코일이 감겨 자로를 형성하는 철심으로 구성되어 있으며, 이 권선코일의 단자를 외부로 인출하기 위한 부싱이 연결되어 있다. In general, a transformer converts high voltage into low voltage and transmits and distributes power, and is composed of a plurality of winding coils having mutual induction and iron cores which are wound around the winding coils to form a magnetic path. The bushings are connected.

이와 같은 기술과 관련되어 특허 제818958호에 변압기용 부싱의 기술이 제시되고 있으며 그 구성은 도1에서와 같이, 변압기의 외함(30)에 형성된 통공(31)의 내외측에 기밀이 유지되도록 결합되는 외측 및 내측 애자(32,33)와, 이외측 및 내측 애자(32,33)에 관통되어 변압기 내의 전압을 외부에 인가시키는 중심도체(34)가 구비되고, 상기 외함(30)의 내부에는 절연유가 충전되며, 상기 중심도체(34)는 외함(30)의 내부에서 외부로 연장되는 로드(35)와 이 로드(35)의 종단에 일체로 형성되어 외부 도선에 결합되는 터미널(36)로 이루어지며, 상기 로드(35)의 내부에는 절연유가 유입되도록 길이방향을 따라 장홀(38)이 형성되고, 상기 로드(35)와 애자(32,33) 사이에는 상기 장홀(38)과 연통되어 절연유가 유입되는 유입공간(41)이 형성되며, 상기 외측 애자(32)의 저면에는 요홈(39)이 형성되고, 내측 애자(33)의 상면에는 상기 요홈(39)에 삽입되는 돌기부(40)가 형성되는 구성으로 이루어 진다.In connection with such a technique, a technique of a bushing for a transformer is proposed in Patent No. 818958, and its configuration is coupled to maintain airtightness inside and outside of the through hole 31 formed in the enclosure 30 of the transformer. And outer and inner insulators 32 and 33, and a center conductor 34 penetrating through the outer and inner insulators 32 and 33 to apply a voltage in the transformer to the outside, and inside the enclosure 30. Insulating oil is filled, and the center conductor 34 is a rod 35 extending from the inside of the enclosure 30 to the outside and a terminal 36 integrally formed at an end of the rod 35 and coupled to an external conductor.
