Description

수지 몰드형 변압기의 코일 구조{Coil structure for resin mold type transformer}Coil structure for resin mold type transformer

본 발명은 수지를 사용하여 몰딩된 변압기용 코일 구조에 관한 것으로, 특히 코일을 여러개의 섹션으로 분리하여 제작한 후 조립할 수 있도록 구성된 코일 구조에 관한 것이다.The present invention relates to a coil structure for a transformer molded using a resin, and more particularly to a coil structure configured to be assembled by separating the coil into a plurality of sections.

일반적으로 수지 몰드형 변압기의 코일은 도 1과 같이 금형을 이용한 진공 주형방식에 의해 제작된다.In general, a coil of a resin mold type transformer is manufactured by a vacuum casting method using a mold as shown in FIG. 1.

즉, 내측금형(21)의 바깥둘레에 여러개의 섹션으로 구분하여 권선된 코일(1)을 일정한 절연거리가 유지되도록 배열한 후 각 섹션별 코일을 연결구에 의해 연결하고 코일의 바깥측에 외측금형(22)을 조립하여 일체화 한 다음 내측금형(21)과 외측금형(22)사이의 공간에 에폭시 수지를 충진하여 코일을 제작하였다.That is, after arranging the coils 1 wound around the outer mold of the inner mold 21 into a plurality of sections to maintain a constant insulation distance, the coils of each section are connected by the connector and the outer mold on the outer side of the coil. After assembling and integrating (22), an epoxy resin was filled in the space between the inner mold 21 and the outer mold 22 to produce a coil.

도 2 내지 도4는 상기와 같은 방법으로 제작된 수지 몰드형 변압기의 코일을 나타낸 도면으로서, 에폭시 수지물(2)내에 여러개의 섹션으로 구분하여 권선된 코일(1)이 몰딩되어 있고 여러개의 섹션으로 구분된 각 섹션별 코일은 연결구(3)에 의해 전기적으로 연결되어 있다.2 to 4 are diagrams showing coils of a resin-molded transformer manufactured by the above method, in which the coil 1 wound by dividing into several sections in the epoxy resin material 2 is molded and divided into several sections. The divided coils of each section are electrically connected by the connector 3.

그러나 상기와 같은 종래의 수지 몰드형 코일은 여러개의 섹션별로 권선작업을 한 후 내측금형(21)에 절연거리가 유지되도록 배열한 상태에서 결선작업을 하고 다시 외측금형(22)을 조립하여야 하므로 작업이 매우 복잡하고 시간이 많이 소요되며, 외측금형을 씌우는 과정에서 섹션별로 구분된 각 코일의 배열상태가 변화되어 절연파괴를 유발할 우려가 있다.However, the conventional resin mold-type coil as described above, after the winding work for several sections, the wiring work in a state in which the insulation distance is maintained on the inner mold 21, and the outer mold 22 needs to be assembled again. It is very complicated and time consuming, and in the process of covering the outer mold, the arrangement of each coil divided into sections may change, causing insulation breakdown.

또한 외측금형의 셋팅이 완료된 후에는 금형의 내부를 육안으로 볼 수 없기때문에 상기한 바와 같이 각 코일의 배열상태가 변화되거나 또는 각 코일간의 결선상태가 불량하여도 이를 확인하여 수정할 수 없는 결점이 있다.In addition, since the inside of the mold cannot be visually seen after the setting of the outer mold is completed, there is a defect that cannot be checked and corrected even if the arrangement state of each coil is changed or the connection state between each coil is poor as described above. .

그리고 제품으로 조립하여 사용하는 과정에서 여러 섹션의 코일중 어느 하나의 섹션의 코일이 소손되는 경우에도 그 부분만 교체하는 것이 불가능하여 코일 전체를 사용할 수 없게 되는 문제도 있다.In the process of assembling and using the product, even if the coil of any one section of the coil of the section is burned out, there is a problem in that it is impossible to replace only the part and thus the whole coil cannot be used.

본 발명의 목적은 여러 섹션의 코일을 에폭시 수지물에 의해 일체형으로 고정하는 종래 구조와는 달리 코일을 섹션별로 분리하여 독립적으로 구성함으로서 조립의 편리성을 도모하고 자동적으로 코일간의 절연거리가 확보될 수 있는 수지 몰드형 변압기의 코일을 제공하기 위한 것이다.The object of the present invention is to facilitate the assembly and to ensure the insulation distance between the coils automatically by separating the coils by sections, unlike the conventional structure in which the coils of several sections are integrally fixed by epoxy resin. It is to provide a coil of a resin molded transformer that can be.

상기 목적을 달성하기 위한 본 발명의 실시예에 따라 에폭시 수지물내에 하나의 섹션 코일을 내장하여 단위체를 구성하고 각 단위체의 일측 상면과 저면에는 코일과 연결된 도전부를 설치하여 각 단위체를 조립함에 따라 각 코일이 연결되게 하며, 상기 각 단위체의 상면과 저면에 단위체의 조립을 위한 형합돌기부와 형합홈부를 형성하여서 된 수지 몰드형 변압기의 코일 구조가 제공된다.In accordance with an embodiment of the present invention for achieving the above object by constructing a unit unit by embedding a single section coil in the epoxy resin material and by installing a conductive portion connected to the coil on one side upper and lower surfaces of each unit to assemble each unit The coil structure of the resin mold transformer is provided by connecting the coils and forming a molding protrusion and a fitting groove for assembling the units on the top and bottom surfaces of the units.

도 5 내지 도 9는 본 발명에 따른 수지 몰드형 변압기의 코일을 나타낸 도면으로서, 본 발명의 코일은 여러개의 섹션별 단위체로 구성되어 하나의 코일로 조립된다.5 to 9 is a view showing a coil of a resin-molded transformer according to the present invention, the coil of the present invention is composed of a unit for each section is assembled into a single coil.

각 단위체는 권선된 한개의 코일(11)과 이 코일을 둘러싼 에폭시 수지물(12)로 이루어져 있으며, 각 단위체의 상면에는 형합돌기부(13)와 도전부(14)가 설치되어 있고 코일(11)의 일측 끝단은 상기 도전부(14)에 전기적으로 연결되어 있다.Each unit consists of one coil 11 wound around and an epoxy resin 12 surrounding the coil, and a mold-matching protrusion 13 and a conductive part 14 are provided on the upper surface of each unit, and the coil 11 One end of the is electrically connected to the conductive portion (14).

또한 각 단위체의 저면에는 상기 형합돌기부(13)가 형합될 수 있는 형상의 형합홈부(15)와 도전부(16)가 형성되어 있고 코일(11)의 반대측 끝단은 상기 도전부(16)에 전기적으로 연결되어 있다.In addition, a matching groove 15 and a conductive part 16 are formed on the bottom of each unit to form the matching protrusion 13. The opposite end of the coil 11 is electrically connected to the conductive part 16. Is connected.

그리고 조립시 최상방에 위치하는 단위체에는 형합돌기부(13)와 도전부(14)가 설치되어 있지 않다.The assembly protrusion 13 and the conductive portion 14 are not provided in the unit located at the top of the assembly.

상기와 같이 된 본 발명은 각 섹션별 단위체를 여러개 조립하여 하나의 코일을 구성하게 되는데, 각 단위체를 조립하면 삼면에 설치된 형합돌기부(13)가 그 상방에 위치된 단위체의 형합홈부(15)내로 끼워져 결합됨과 동시에 각 도전부(14)(16)가 접속되면서 각 단위체의 코일(11)이 전기적으로 연결되어 하나의 코일을 이루게 되는 것이다.The present invention as described above constitutes a single coil by assembling a plurality of units for each section, when each unit is assembled, the mating protrusions 13 installed on three sides into the mating groove 15 of the unit located above. At the same time, the conductive parts 14 and 16 are connected to each other, and the coil 11 of each unit is electrically connected to form one coil.

상기와 같이 코일을 섹션별로 분리하여 제작하면 각 단위체를 구성하는 우레탄 수지물(12)의 두께에 의해 각 단위체를 조립하였을 때 각 코일간의 거리가 자동적으로 일정 거리만큼 유지된다.When the coil is separated and manufactured as described above, when the unit is assembled by the thickness of the urethane resin material 12 constituting each unit, the distance between each coil is automatically maintained by a predetermined distance.

본 발명은 섹션별로 분리된 여러개의 단위체를 결합하여 하나의 코일을 구성하도록 되어 있기 때문에 코일의 조립작업이 용이해지고 자동적으로 각 코일간의 절연거리가 유지되어 절연성능을 확보할 수 있게 된다.In the present invention, since a single coil is formed by combining a plurality of units separated by sections, assembling work of the coil is facilitated, and an insulation distance between the coils is automatically maintained to ensure insulation performance.

또한 각 단위체를 쉽게 분리할 수 있으므로 사고로 인해 여러 섹션의 코일중일부의 코일이 소손되는 경우 소손된 섹션의 코일만 교체하여 사용할 수 있게 되며, 따라서 일부 코일의 소손시 코일 전체를 폐기하거나 재작업을 하여야 했던 종래 구조에 비해 경제적 손실을 줄일 수 있고 신속한 수리작업이 가능해진다.In addition, since each unit can be easily separated, if a coil is damaged in one of several sections due to an accident, only the coil in the section that has been burned out can be replaced. Compared with the conventional structure, which had to be done, economic loss can be reduced and rapid repair work is possible.
