본 고안은 수중모터의 방수처리를 함에 있어 메카니칼시일과 오-링 등의 밀폐가 완벽한 분야를 제외한 모터의 케이블 인출구의 방수처리를 함에 있어 수압에 대한 밀폐성과 절연성이 양호한 600V 고무절연캡타이어케이블을 에폭시 몰딩으로 방수처리 하는데 이때 도체(소선)로 침투되는 물의 방수처리를 완벽하게 할수있게한 수중모터용 방수장치에 관한 것이다.The present invention is a 600V rubber insulated capti cable with good sealing and insulation against water pressure in the waterproofing of the cable outlet of the motor except for the sealing of mechanical seal and O-ring. It is waterproofing with epoxy molding, and it relates to a waterproofing device for underwater motors, which makes it perfect for waterproofing of water penetrating into conductors (wires).

종래에 사용되어온 수중모터용 케이블의 방수장치는 600V고무절연 캡타이어케이블을 사용하여 수중모터용 케이블 인출상자에서 몰딩보호 튜브를 씌워서 그 공간에 에폭시몰딩 충진재를 배합하여 응고(화학반응)시켜서 사용하는 관계로 케이블의 피복부분이 파손되거나 인출부의 절연처리가 미흡할때 선심 사이의 에폭시몰딩 충진재로 방수치리를 하는데 그쳤다. 지하 또는 수중에서 사용시 사소한 부주의로 인하여 인출부의 끝단이든가 심선의 절연층까지 피복이 벗겨져, 도체(소선)부분의 틈새로 물이 침투되는 일이 빈번하였다. 이의 보완 사항으로 몰딩부분에 해당하는 전선의 절연체를 벗겨내고 에폭시몰딩이 도체(심선)선 가닥사이 틈새로 완벽히 몰딩 되도록하였다. 그러나 허용수압에 견디지 못하는등 다소 보완은 되었으나 계속 도체(소선)사이의 틈새로 부터 흘러 들어오는 물(유체)을 완벽히 방수처리하지 못하여 수중모터의 절연파괴로 인한 모터소손의 주된 원인이 되었다.The waterproofing device of the cable for submersible motors used in the prior art uses a 600V rubber insulated captire cable to cover the molding protective tube in the cable extraction box for submersible motors, and to solidify (chemical reaction) by mixing the epoxy molding filler in the space. As a result, when the sheath of the cable was broken or the insulation of the lead part was insufficient, it was only waterproof with epoxy molding filler between the cores. Due to minor carelessness when used underground or in the water, the end of the lead-out part or the coating is peeled off to the insulation layer of the core wire, and water frequently penetrates into the gap of the conductor (wire wire) part. As a supplement, the insulation of the wire corresponding to the molding part was peeled off, and the epoxy molding was completely molded into the gap between the conductor (core) wire strands. However, although it was supplemented somewhat by not being able to withstand the hydraulic pressure, the water (fluid) flowing from the gap between the conductors (wires) could not be completely waterproofed, which was the main cause of motor damage due to the insulation breakdown of the underwater motor.

또한 수중모터펌프는 사용하는 장소가 수중이므로 방수처리가 미흡한 관계로 고장시 중량물을 지상에 까지 끌어 올리는 등 그 과정이 매우 어렵고 물의 처리(배수,급수)에 많은 지장을 초래하는 등의 결점이 있었다.In addition, the submersible motor pump is used in water, so the waterproof process is insufficient. Therefore, the process is very difficult, such as lifting heavy materials to the ground in case of failure and causing a lot of problems in water treatment (draining and watering). .

본 고안은 전술한 바와 같은 종래의 제결점에 착안하여 인출한 것으로서 고안의 요지를 첨부 도면에 의하여 상세히 설명하면 다음과 같다.The present invention is drawn out from the conventional drawbacks as described above, and the subject matter of the present invention will be described in detail with reference to the accompanying drawings.

내수성이 강한 600V 고무절연캡타이어 케이블을 인출선으로 사용하고 인출선 연결부위의 4가닥의선은 절연처리가 양호하도록 몰딩 보호튜브(10)를 사용하여 외부로부터 1차적인 방수처리를 한후 케이블의 도체(12)를 몰딩부분에 맞추어 절단한후 절연체(4)를 벗겨낸후 밀폐형연결스리브(9)를 연결한후 터미널압착기로 압착한다음선심(12)간이 접촉되지않도록 간격을 벌린후 에폭시몰딩충진재(8)로 몰딩처리하였다.The water resistant 600V rubber insulated captire cable is used as a lead wire, and the four strands of the lead wire connection part are first waterproofed from the outside by using a molding protection tube (10) for good insulation treatment. After cutting the conductor 12 to the molding part, remove the insulator 4, connect the hermetic connection sleeve 9, and crimp it with a terminal crimp. Then, open the gap so that the wire cores 12 do not come into contact with the epoxy molding filler. Molding was carried out with (8).

이와같이 된 본 고안은 수중모터펌프의 중간부나 끝단부위(외부전원 연결부위)로부터 스며드는 물(액체)중 선심사이의 틈새는 에폭시몰딩 충진재(8)로 방수처리되며 수압에 의해 도체(2) 사이로 스며드는 물(액체)은 밀폐형연결스리브에 의해 스며드는 물(액체)을 차단시켜 주기때문에 방수 효과를 완벽히 할수있어 케이블인출부의 방수처리미흡으로 인한수중모터 펌프의 고장으로 인한 손실을 방지할수 있어 물 침투에 의한 모터절연 파괴의 고장원인을 근본적으로 해결하는 효과를 가질수있다.In this way, the gap between the cores of the water (liquid) that permeates from the middle part or the end part (external power connection part) of the submersible motor pump is waterproofed with the epoxy molding filler (8) and permeated between the conductors (2) by water pressure. Water (liquid) blocks water (liquid) permeated by hermetic connection sleeves, which makes it possible to achieve a perfect waterproof effect, thus preventing the loss of the underwater motor pump due to insufficient waterproofing of the cable outlet. It can have the effect of fundamentally solving the cause of failure of motor insulation breakdown.

본 고안은 수중모터용케이블(600V 고무절연캡타이어케이블1,1',1",1''') 인출부의 방수장치를 다음의 시험조건하에서 시험한 결과 밀폐형연결스리브(9)를 사용하여 방수처리한 결과는 아래 표와 같다.The present invention was tested for the waterproofing device of the submersible motor cable (600V rubber insulated cap tire cable 1,1 ', 1 ", 1' '') under the following test conditions. The results are shown in the table below.
