이하 본 고안을 첨부된 도면에 의햐 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.
도 2에 도시된 바와 같이 투명한 합성수지재질로 구성된 본 고안에 의한 할개된 절연커버(20)상단은 내부에 환형의 제1내지 제2돌출부(21, 22)가 형성되어 있어 피뢰기(10)하부의 금속충진부(12)와 체결을 견고하게 하여 바람등 외부의 진동으로 부터 상기절연커버(20)가 피뢰기(10)로 부터 이탈되지 않도록 훅크와 같은 잠금장치로 고정되도록 구성되어 있으며, 특히 제2돌출부(22)는 상기 금속충진부(12)에 생기는 물기가 쉽게 아래로 배수될수 있도록 제2돌출부(22)는 소정의 간격마다 절개되어 있으며, 상기 할개된 절연커버(20)의 계합면은 외부로부터 절연커버(20)내부로 물기·오염물질등 위해요소가 침투되지 못하고 밀착계합될수 있도록 일측 절연커버(20)의 계합면에는 돌설요부(凸)를 형성하고 체결되는 타측절연커버(20)의 대응 계합면은 철부(凹)를 형성시켜 계합체결시 견고성을 높이도록 구성하되 상기 돌설요부와 철부의 단면은 삼각형 사각형 반원형등 본 고안에 한정되지 않고 다양하게 변형하여 실시할수가 있으며 상기 할개된 절연커버(20)의 하단은 단로기가 파손될 경우 금속충진부로 부터 분리되어 본 고안의 절연커버(20)로 부터 용이하게이탈되고 내부에 생성되는 물기가 상기절연커버(20)외부로 쉽게 배수될수 있도록 단로기의 직경보다 소정의 길이 만큼 큰직경으로 외부로 형성된 접지선 인출공(27)이 형성되어 있다.As shown in FIG. 2, the upper part of the insulating cover 20 according to the present invention composed of a transparent synthetic resin material has an annular first to second protrusions 21 and 22 formed therein, so that the lower part of the arrester 10 is formed. It is configured to be firmly fastened with the metal filling part 12 so as to be fixed by a locking device such as a hook so that the insulating cover 20 is not detached from the arrester 10 from external vibrations such as wind. The protrusion 22 has a second protrusion 22 is cut at predetermined intervals so that water generated in the metal filling part 12 can be easily drained down, and the engagement surface of the split insulation cover 20 is external. The other side of the insulating cover 20 is formed with a protrusion on the mating surface of the insulating cover 20 so that harmful elements such as water and pollutants do not penetrate into the insulating cover 20 from the inside. Corresponding engagement surfaces form convexities When the engagement is configured to increase the rigidity, but the cross-section of the protrusion and the convex portion is not limited to the present invention, such as the triangular square semi-circle can be variously modified and the lower end of the split insulation cover 20 is to be disconnected breaker In this case, it is separated from the metal filling part to be easily separated from the insulating cover 20 of the present invention, and the water generated therein can be easily drained to the outside of the insulating cover 20 by a predetermined diameter larger than the diameter of the disconnector. The ground wire drawing hole 27 formed outside is formed.
한편 도 3에서와 같이 본 고안의 피뢰기하부 절연커버(20)가 피뢰기에 계합체결시 상기 절연커버(20)의 계합요부(23)와 계합철부(24) 및 힌지구조의 체결공(25)와 체결돌기(26)을 나타낸 것으로, 할개된 반원 기둥형상의 절연커버(20)에 있어 외부일측의 체결공(25)과 외부 타측의 체결돌기(26)는 하나이상 소정의 힌지구조로 체결될수 있도록 끼움형태로 하되 할개된 상기 반원기둥 형상의 절연커버의 계합면 일측은 계합요부(23)가 타측은 계합철부(24)가 형성되어 있으며, 상기 체결공(25)과 체결돌기(26)로 이루어진 힌지구조역시 본고안에 한정되지 않고 다양한 모양으로 실시하여 체결할수가 있는 것이다.Meanwhile, as shown in FIG. 3, when the lightning arrester lower insulation cover 20 of the present invention is engaged with the arrester, the engaging recess 23, the engaging convex portion 24, and the hinge hole 25 of the insulation cover 20 are engaged with the lightning arrester. The fastening protrusions 26 are shown in the insulating cover 20 of the split semicircular column shape so that the fastening holes 25 on one side and the fastening protrusions 26 on the other side can be fastened to one or more predetermined hinge structures. One side of the engagement surface of the semi-cylindrical insulating cover, which is fitted in the form of a split, the engaging recess 23 is formed on the other side, and the engaging convex portion 24 is formed, and the fastening hole 25 and the fastening protrusion 26 are formed. The hinge structure is also not limited to this article and can be implemented by various shapes.
본 고안에 의한 피로기 하부절연커버는 착탈이 용이하도록 힌지구조 계합 체결하는 형상으로 피뢰기 하부에 설치하도록 되어 있어 전위상승에 따른 감전이나 설비보호를 위한 위해요소로 부터 안전성을 확보할수가 있을뿐아니라 투명재질로 되어 있어 내부를 육안으로 용이하게 관찰할수가 있기때문에 피뢰기 하단에 연결되어 있는 단로기의 파손여부도 쉽게 확인이 가능하다는 효과가 있는 것이다.The lower fatigue cover of the present invention according to the present invention is installed in the lower part of the arrester in the shape of engaging the hinge structure so that the attachment and detachment is easy, and it can not only secure safety from the hazards for electric shock or facility protection due to the potential rise. Since the transparent material makes it easy to observe the inside with the naked eye, the breaker connected to the lower part of the arrester can be easily checked.
