이하 첨부된 도면을 참조로 본 발명의 바람직한 실시 예를 상세히 설명하기로 한다. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 1에는 본 발명에 따른 함침용 설비(10)를 나타낸 정 단면도가 도시되어 있고, 도 2에는 도 1의 측 단면도가 도시되어 있다.FIG. 1 shows a cross sectional view of an impregnation device 10 according to the present invention, and FIG. 2 shows a side cross sectional view of FIG.

도면에 도시된 바와 같이 함침용 설비(10)는, 외부 챔버(12)에 내부 챔버(14)가 수용되는 상태로 배치되는 이중 구조로 이루어지며, 외부 및 내부 채버(12,14)가 서로 대응하는 양 측면에는 제품(16)이 통과하는 형태로 지나갈 수 있도록 통공(18,20)이 각각 형성된다.As shown in the figure, the impregnation facility 10 has a double structure in which the inner chamber 14 is accommodated in the outer chamber 12, and the outer and inner chabers 12 and 14 correspond to each other. Both sides are formed through holes 18, 20 so that the product 16 can pass in the form of passage.

또한, 상기 외부 및 내부 챔버(12,14) 간에는 회수관(22)이 연결되는데, 이때 회수관(22)의 일 측은 외부 챔버(12)에 삽입되어 있고, 타 측은 내부 챔버(14)의 상면을 관통하는 상태로 설치된다.In addition, a recovery tube 22 is connected between the outer and inner chambers 12 and 14, wherein one side of the recovery tube 22 is inserted into the outer chamber 12, and the other side is an upper surface of the inner chamber 14. It is installed in a state penetrating.

그와 함께 상기 회수관(22) 상에는 외부 챔버(12)에 존재하는 절연유(24)가 내부 챔버(14)로 회수될 수 있도록 펌프인 동력수단(26)이 구비되어 있다.In addition, on the recovery pipe 22, a power means 26 serving as a pump is provided so that the insulating oil 24 existing in the outer chamber 12 can be recovered to the inner chamber 14.

또한, 상기 내부 챔버(14)에는 절연유 공급설비와 연결되는 공급관(28)이 외부 챔버(12)의 상면을 관통하여 내부 챔버(14)에 연결되어 있으므로 해서, 공급관(28)으로부터 이송되는 절연유(24)가 내부 챔버(14)의 내부로 공급되게 된다.In addition, since the supply pipe 28 connected to the insulating oil supply facility is connected to the inner chamber 14 through the upper surface of the outer chamber 12, the inner chamber 14 is supplied with the insulating oil transferred from the supply pipe 28 ( 24 is supplied into the interior chamber 14.

아울러, 상기 공급관(28)으로부터 이격된 위치에는 진공도 조절 및 유지시키기 위하여 진공관(30)이 진공펌프(32)와 연결되어 있다.In addition, the vacuum tube 30 is connected to the vacuum pump 32 to control and maintain the degree of vacuum at a position spaced apart from the supply pipe 28.

또한, 상기 내부 챔버(14)의 내면에는 전기적인 통전에 의해 발열 되는 복수개의 발열부재(34)이 서로 전기적으로 연결되는 상태로 배치되어 부착 고정되어 있다. 이러한 발열부재(34)는 양측 단에 양극(a)과 음극(b)이 구비되고, 이 양극(a)과 음극(b)을 연결하는 도전 코일(도시되지 않음)이 발열부재(34) 속에 내장되어 봉합된 구조로 이루어지며, 외부의 전원공급장치와 전기인 연결에 의해 전원공급을 받아 발열하게 된다. 참고로 발열부재(34) 간에는 병렬로 연결되는 것이 바람직할 것이다. In addition, the inner surface of the inner chamber 14 is disposed and fixed in a state in which a plurality of heat generating members 34, which are generated by electric current, are electrically connected to each other. The heating member 34 is provided with a positive electrode (a) and a negative electrode (b) at both ends, and a conductive coil (not shown) connecting the positive electrode (a) and the negative electrode (b) is formed in the heat generating member 34. It is made of a built-in and sealed structure, and generates heat by receiving power by connecting with an external power supply device. For reference, it will be preferable to be connected in parallel between the heating member (34).

그러나, 위의 발열부재(34)가 위와 같은 구조로 한정될 필요는 없으며, 전기적인 통전에 의해 열을 발생시킬 수 있다면 어떤 것을 구조 및 부품의 채용도 무방할 것이다.However, the heat generating member 34 need not be limited to the above structure, and any structure and parts may be employed as long as it can generate heat by electric current.

하기에 서는 함침용 설비(10)를 이용한 절연유(24)의 도포 및 함침 과정을 설명하기로 한다. Hereinafter, the application and impregnation process of the insulating oil 24 using the impregnation facility 10 will be described.

먼저, 제품(16)은 외부 및 내부 챔버(12,14)의 통공(18,20)을 관통하여 지나가는 상태가 된다. 이와 동시에 공급관(28)으로부터 공급되는 절연유(24)가 내부 챔버(14)에 수용되는 상태로 채워지게 되면서 제품(16)이 절연유(24)에 잠기게 되어 완전한 도포가 가능하게 된다.First, the product 16 passes through the through holes 18 and 20 of the outer and inner chambers 12 and 14. At the same time, as the insulating oil 24 supplied from the supply pipe 28 is filled in the state accommodated in the inner chamber 14, the product 16 is immersed in the insulating oil 24, thereby enabling complete application.

위와 같이 상기 제품(16)의 도포가 완료되는 동안 진공펌프(32)가 구동되어 내부 챔버(14)에 존재하는 기체를 외부로 배출시켜 진공도를 지속적으로 형성 및 유지시킴으로써, 요구하는 함침이 이루어질 수 있게 된다. While the application of the product 16 is completed as described above, the vacuum pump 32 is driven to discharge the gas present in the inner chamber 14 to the outside to continuously form and maintain the degree of vacuum, so that the required impregnation can be made. Will be.

그와 함께, 상기 외부 및 내부 챔버(12,14)의 통공(18,20)을 막아 진공도를 더욱 향상시킬 수 있도록 깔때기 형상의 실링부재(36)가 상기 통공(18,20)에 각각 결합 되어, 궁극적으로 함침 능력을 배가시킬 수 있게 된다. At the same time, a funnel-shaped sealing member 36 is coupled to the through holes 18 and 20 to block the through holes 18 and 20 of the outer and inner chambers 12 and 14 to further improve the degree of vacuum. Ultimately, this will double the impregnation capacity.

위와 같은 과정을 수행하는 동안 상기 실링부재(36)가 개재되어 있더라도, 미세한 틈새를 통해 내부 챔버(14)의 통공(20)으로부터 외부 챔버(12)로 절연유(24)가 흐르게 된다. 이러한 절연유(24)의 회수를 위하여 동력수단(26)이 구동되고, 그에 따라 외부 챔버(12)에 존재하는 절연유(24)가 회수관(22)을 따라 내부 챔버(14)로 회수되는 일련의 동작이 반복적으로 이루어지게 된다.Even when the sealing member 36 is interposed during the above process, the insulating oil 24 flows from the through hole 20 of the inner chamber 14 to the outer chamber 12 through a minute gap. In order to recover the insulating oil 24, the power means 26 is driven, so that the insulating oil 24 existing in the outer chamber 12 is returned to the inner chamber 14 along the recovery pipe 22. The operation is repeated repeatedly.

또한, 상기 내부 챔버(14)에 구비되는 발열부재(34)의 발열에 의하여 외부 및 내부 챔버(12,14)에 수용되는 절연유(24)의 굳어짐이 방지되며, 그로 인해 균일한 도포 및 충분한 함침은 물론, 최적의 작업성을 발휘할 수 있게 된다.  In addition, hardening of the insulating oil 24 accommodated in the outer and inner chambers 12 and 14 is prevented by the heat generation of the heat generating member 34 provided in the inner chamber 14, thereby uniform coating and sufficient impregnation. Of course, the optimum workability can be exhibited.

이상과 같이, 본 발명은 비록 한정된 실시 예와 도면에 의해 설명되었으나, 본 발명은 이것에 의해 한정되지 않으며 본 발명이 속하는 기술분야에서 통상의 지식을 가진 자에 의해 본 발명의 기술사상과 아래에 기재될 특허청구범위의 균등범위 내에서 다양한 수정 및 변형 가능함은 물론이다.As described above, although the present invention has been described by way of limited embodiments and drawings, the present invention is not limited thereto and is intended by those skilled in the art to which the present invention pertains. Of course, various modifications and variations are possible within the scope of equivalents of the claims to be described.
