주상변압기 1차부싱의 하부연결 애자지지판 구조{Insulator Supporting Panel Exterior Structure of Pole Transformer Primary-Bushing}Insulator Supporting Panel Exterior Structure of Pole Transformer Primary-Bushing}

본 고안은 배전선로 주상변압기 1차부싱에 연결되는 하부연결 애자지지판 구조에 관한 것으로, 특히 애자지지판과 주상변압기 사이에 장착되는 고무패킹이 햇볕,비,눈 등에 직접 노출되는 것을 방지하여 자연열화에 의한 소손을 방지하는 개선된 주상변압기 1차부싱의 하부연결 애자지지판 구조에 관한 것이다.The present invention relates to the structure of the lower connection insulator support plate connected to the primary bushing of the distribution line of the distribution line, and in particular, the rubber packing mounted between the insulator support plate and the column transformer prevents direct exposure to sunlight, rain, snow, etc. The lower connection insulator support plate structure of the improved columnar transformer primary bushing to prevent damage caused by the present invention.

통상 배전선로상에 시설되는 주상변압기에는 1차부싱 단자와의 사이에 애자가 설치되어 서로 연결되어 있는 바, 즉 이 1차부싱 연결부위의 애자(104)부분이 도 3과 같이 고무패킹(102)을 매개로 주상변압기의 외함상부(101)부분에 설치되어 있는데, 종래 이 1차부싱 연결부위의 애자(104)부분에 설치되는 고무패킹(102)은 이 애자(104)의 애자지지판(105) 접촉 단면적과 거의 동일한 크기로 개재되어 있기 때문에 자연열화요인인 햇볕,비,눈 등에 직접적으로 노출되어 있어서 주상변압기측으로 수분이 침투할 우려가 있으며, 실제 현장에서도 이러한 이유로 인해 주상변압기의 수명이 단축되는 실정이다.Normally, the columnar transformer installed on the distribution line is provided with insulators between the primary bushing terminals and connected to each other, that is, the insulator 104 portion of the primary bushing connection portion is rubber-packed 102 as shown in FIG. 3. It is installed in the upper part 101 of the outer box of the columnar transformer, the rubber packing 102 is installed on the insulator 104 of the primary bushing connection portion is the insulator support plate 105 of the insulator 104 Since it is almost the same size as the contact cross-sectional area, it is directly exposed to sunlight, rain and snow, which is a natural deterioration factor, so that water may penetrate into the columnar transformer side. It is a situation.

또한 최근의 변압기 내부철심이나 코일은 그 동안 획기적인 기술발전으로 절연 등의 강도면에서 아주 양호하나 눈여겨 보아야 할 부분인 주상변압기 1차부싱 연결부위의 고무패킹은 열 또는 수분 및 연결부분의 압축강도에 대한 정밀도가 소홀히 다루어지고 있는 실정이다.In addition, recently, the inner core of a transformer or coil has been very good in terms of strength such as insulation due to the breakthrough technological development, but the rubber packing of the primary bushing connection part of the column transformer, It is a situation that is neglected.

이에 본 고안은 상기와 같은 종래 문제점을 해결하기 위해 안출된 것으로, 주상변압기에 연결되는 애자지지판의 자연열화촉진을 최대한으로 감소시키어 주상변압기의 소손을 방지하는 개선된 주상변압기 1차부싱의 하부연결 애자지지판 구조를 제공함에 그 목적이 있다.Therefore, the present invention has been made to solve the conventional problems as described above, the lower connection of the improved columnar transformer primary bushing to prevent the burnout of the columnar transformer by reducing the natural degradation promotion of the insulator support plate connected to the columnar transformer to the maximum The purpose is to provide an insulator support plate structure.

상기와 같은 목적을 달성하기 위한 본 고안은 주상변압기의 상부면에서 고무패킹을 매개로 1차부싱 단자를 갖춘 애자를 시설하는 애자지지판 구조에 있어서, 상기 애자지지판의 단면적이 고무패킹의 단면적보다 크게 되어 이 고무패킹이 애자지지판의 안쪽으로 들어가서 개재되는 구조로 되어 있다.The present invention for achieving the above object is in the insulator support plate structure for installing the insulator with the primary bushing terminal via the rubber packing in the upper surface of the columnar transformer, the cross-sectional area of the insulator support plate is larger than the cross-sectional area of the rubber packing This rubber packing is structured to enter the inside of the insulator support plate.

이하 본 고안을 첨부된 예시도면에 의거 상세히 설명한다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 고안이 적용되는 주상변압기(1)의 부분 정면도이고, 도 2는 본 고안의 요부 단면도이다.1 is a partial front view of a columnar transformer 1 to which the present invention is applied, and FIG. 2 is a cross-sectional view of main parts of the present invention.

본 고안은 도면에 도시된 바와 같이 주상변압기(1)의 상부면에서 고무패킹(2)을 매개로 1차부싱 단자(3)를 갖춘 애자(4)를 시설하는 애자지지판 구조에 있어서, 상기 애자지지판(5)의 단면적이 고무패킹(2)의 단면적보다 크게 설정되어, 이 고무패킹(2)이 애자지지판(5)의 안쪽으로 들어가서 개재되는 구조로 되어 있다.The present invention, in the insulator support plate structure for installing the insulator (4) having the primary bushing terminal (3) via the rubber packing (2) on the upper surface of the columnar transformer (1) as shown in the figure, the insulator The cross-sectional area of the support plate 5 is set larger than the cross-sectional area of the rubber packing 2, and this rubber packing 2 enters the inside of the insulator support plate 5 and is interposed.

즉 본 고안은 애자지지판(5)을 고무패킹(2)보다 면적을 넓게 하여 시설함으로써, 상기 고무패킹(2)이 애자지지판(5)과 주상변압기(1)의 상부면 사이에 장착되게 되면, 이 애자지지판(5)이 고무패킹(2)의 직접적인 외부 노출을 방지하여 햇볕,비,눈과 같은 자연열화요인으로부터 고무패킹(2)이 직접적으로 노출되는 것을 차단하게 된다.In other words, the present invention by installing the insulator support plate (5) wider than the rubber packing (2), when the rubber packing (2) is mounted between the insulator support plate (5) and the upper surface of the columnar transformer (1), The insulator support plate 5 prevents the direct external exposure of the rubber packing 2 to prevent the rubber packing 2 from being directly exposed from natural deterioration factors such as sunlight, rain and snow.

따라서 상기 고무패킹(2)의 열화촉진의 가속화를 방지하고, 특히 크랙 및 트리현상에 의한 수분침투로 발생되는 주상변압기의 소손을 방지할 수 있다.Therefore, it is possible to prevent the acceleration of the deterioration acceleration of the rubber packing (2), and in particular to prevent burnout of the columnar transformer caused by moisture penetration by cracks and tree phenomenon.
