본 고안은 트랜스 포머의 절연조에 관련된 것으로서, 특히 트랜스 포머를 구성하는 러 구성부재들 예를들면 1차권선, 필라멘트코일, 패스코어 또는 2차권선등의 절연지 테이핑 공정을 간소화 할 수 있고, 절연효과를 증대시킨 절연구조에 관한 것이다.The present invention relates to an insulation tank of a transformer, and in particular, it is possible to simplify the insulating paper taping process of the constituent components constituting the transformer, for example, primary winding, filament coil, pass core or secondary winding, and insulation effect. It relates to an insulation structure with increased.
종래의 트랜스포머는 제1도에 도시된 바와같이 E형 철심(1)에 2차권(SECONDARY COIL, 2), 필라멘트코일(3), 패스코어(4), 1차권(SECONDARY COIL, 5)을 차례로 적층하고, E형 철심(1)가 용접 후 용접된 E, I형 철심(1,1a)의 하단 또는 측면에 마운팅 브라켓트(6)를 용접하여 구성하였다.Conventional transformers, as shown in FIG. 1, in order to the E-shaped iron core 1, the secondary winding (SECONDARY COIL, 2), the filament coil (3), the pass core (4), the primary winding (SECONDARY COIL, 5) The mounting bracket 6 was constructed by laminating and welding the lower end or side surfaces of the E and I type iron cores 1 and 1a to which the E type iron core 1 was welded after welding.
그리고, 상기 적층구조에 있어서, E형 철심(1) 및 I형 철심(1a)과 각 구성부재(2,3,4,5,6)간의 절연이나 각 구성부재(2,3,4,5,6)사이의 절연은 각각의 절연지(7a∼7d)를 이용하였다.In the laminated structure, the insulation between each of the E-type iron core 1 and the I-type iron core 1a and the constituent members 2, 3, 4, 5, and 6 and the respective constituent members 2, 3, 4, 5 Insulation between and 6 was used for each of insulating papers 7a to 7d.
즉, 2차권선(2)의 절연을 위하여 절연지(7a)로 2차권선(2)의 외주면을 감쌌고, 필라멘트 코일(3)의 상단면에는 절연지(7b)을 끼워놓았으며, 패스코어(4)의 상단면과 측면에는 절연지(7c)로 감쌌다.That is, the outer peripheral surface of the secondary winding 2 was wrapped with the insulating paper 7a to insulate the secondary winding 2, and the insulating paper 7b was sandwiched on the upper surface of the filament coil 3. The top and side surfaces of 4) were wrapped with insulating paper 7c.
또한, 1차권선(5)의 외주면은 절연지(7d)를 감싸서 절연하였다.In addition, the outer circumferential surface of the primary winding 5 was insulated by wrapping insulating paper 7d.
그러나, 상기와 같은 종래의 절연구조는, 트랜스포머를 구성하는 여러구성부재(2,3,4,5)를 각각의 절연지(7a∼7d)로 감싸서 이루어졌기 때문에 절연지(7a∼7d)를 감싸는 테이핑 공정이 매우 길게 이루어져 실용적이지 못하였다.However, since the conventional insulating structure as described above is made by wrapping the various structural members 2, 3, 4, and 5 constituting the transformer with respective insulating papers 7a to 7d, taping to surround the insulating papers 7a to 7d. The process was very long and not practical.
특히, 절연지의 테이핑공정은 통상적으로 작업에 의존해야 하기 때문에 많은 수의 작업자를 필요로 하게 되므로써 인력난에 많은 어려움을 겪는 현실에 비추어 실용적이지 못하였다.In particular, the taping process of insulating paper is not practical in view of the fact that it requires a large number of workers because they usually have to rely on the work, and thus suffer from a lot of difficulties.
뿐만아니라, 종래의 절연구조에서 이용되는 절연지(7a∼7d)는 각각의 사용상태에 알맞게 성형해야 하므로 여러형태의 절연지를 성형하기 위한 여러형태의 금형을 구비해야 하고, 이러한 여러 형태의 금형의 제작 및 사용과정이 복잡하여 가공성이 매우 낮아 실용적이지 못하였다.In addition, since the insulating papers 7a to 7d used in the conventional insulating structure should be molded according to the respective use conditions, the insulating papers 7a to 7d should be provided with various types of molds for forming various types of insulating papers, and the production of such various types of molds. And the use process is complicated, the workability is very low, it was not practical.
따라서 본 고안은 트랜스포머를 구성하는 여러 구성부재의 절연기 단순한 구조로 이루어질 수 있는 절연구조를 제공함에 그 목적이 있다.Therefore, an object of the present invention is to provide an insulation structure that can be made of a simple structure of the insulator of various components constituting the transformer.
본 고안은 이를 위하여 철심의 구조중에서 1차 및 2차권선등의 구성부재가 끼워지는 공간을 하나의 평면체로 이루어지고 철심의 형상에 대응하여 성형이 가능한 주절연지로 절연시키므로써 1차 및 2차 코일에 별도의 절연구조를 형성하지 않도록 한 것으로서, 이를 첨부한 도면에 도시된 본 고안의 실시예에 따라 상술하면 다음과 같다.In order to accomplish this, the primary and secondary are insulated by the main insulating paper which can be formed to correspond to the shape of the iron core in the structure of the iron core. As not to form a separate insulation structure in the coil, when described in detail according to an embodiment of the present invention shown in the accompanying drawings as follows.
제2도 및 제3도에 도시된 바와같이, 주절연지(8)에는 E형철심(1)의 양 옆면(1e,1d)을 절연하기 위하여 상기 양 옆면(1e,1d)의 각각의 면적보다 같거나 큰 면적을 가지는 옆판(8c,8d)을 각각 형성하고 상기 양 옆판(8e, 8d)의 사이에는 E형 철심(1)의 상면(1c)을 절연하기 위해 상면(1c)의 면적과 같은 면적으로 이루어진 상판(8c)을 일체로 형성한다.As shown in Figs. 2 and 3, the main insulating paper 8 has a larger area than the respective areas of the sides 1e and 1d to insulate both sides 1e and 1d of the E-shaped iron core 1; An area of the upper surface 1c is formed to form side plates 8c and 8d each having the same or larger area, and to insulate the upper surface 1c of the E-shaped iron core 1 between the two side plates 8e and 8d. The upper plate 8c made of the area is integrally formed.
그리고, 상기 옆판(8d)의 일측 연장선상에는 I형 철심(1a)의 저면부와 1차권선(5)과의 절연을 위한 바닥판(8b)을 일체로 형성하고, 상기 바닥판(8b)의 일측 연장선상에는 삽입판(8f)을 이체로 형성한다.On the one side extension line of the side plate 8d, a bottom plate 8b for insulating the bottom portion of the I-type iron core 1a and the primary winding 5 is integrally formed, and the bottom plate 8b is The insertion plate 8f is formed in a variant on one side extension line.
또한, 열판(8e)의 양측에는 E형 철심(1)의 양 측면(1f)을 절연하기 위한 측판(8a)을 일체로 형성한다.In addition, side plates 8a for integrally insulating both side surfaces 1f of the E-shaped iron core 1 are integrally formed on both sides of the hot plate 8e.
상기 측판(8a)은 그 면적이 측면(1f) 면적의 ½이상의 크기가 되도록 형성한다.The side plate 8a is formed such that its area is at least ½ of the area of the side surface 1f.
주절연지(8)를 구성하는 여러판(8a∼8f)는 각각의 면적을 구획하는 경계선상에 엠보싱선(9a∼9e)을 형성하여 접기에 편리하도록하고, 측판(8a)과 상판(8c)에는 절개된 상태의 절개선(9f)을 형성한다.The various plates 8a to 8f constituting the main insulating paper 8 form embossed lines 9a to 9e on the boundary lines that divide the respective areas so as to be convenient for folding, and the side plates 8a and the upper plate 8c are provided. An incision 9f is formed in the cut state.
그리고, 상기 엠보싱선(9a∼9e)과 절개선(9f)은 주절연지(8)의 성형가공시에 하나의 금형에 의해 제작한다.The embossed lines 9a to 9e and the cut line 9f are produced by one mold during the molding processing of the main insulating paper 8.
그러므로, 주절연지(8)를 사용하고자 하는 경우에는 주절연지(8)의 엠보싱선(9a∼9e)을 따라 접으면 주절연지는 제2b도와 같은 형태로 되고, 이와같이 접혀진 상태의 주절연지(8')를 제3도에 도시하는 바와같이 E형 철심(1)의 옆면(1d,1c)과 상면(1c)으로 이루어지는 공간(10a,10a')에 각각 끼워넣는다.Therefore, when the main insulating paper 8 is to be used, when the main insulating paper 8 is folded along the embossed lines 9a to 9e of the main insulating paper 8, the main insulating paper has a shape as shown in FIG. ) Is inserted into the spaces 10a and 10a 'each of the side surfaces 1d and 1c and the upper surface 1c of the E-shaped iron core 1, as shown in FIG.
이때 주절연지(8,8')의 옆면(1d,1e) 및 상면(1c)으로 이루어지는 공간(10a,10a)의 수에 따라 끼워넣는다.At this time, the main insulating paper 8, 8 'is sandwiched according to the number of spaces 10a and 10a each of the side surfaces 1d and 1e and the upper surface 1c.
그리고, 주절연지(8,8')의 양 옆판(8d,8e)과 상판(1c)으로 이루어지는 공간에 2차권선(2), 필라멘트 코일(3), 패스코어(4) 및 1차권선(5)은 차례로 끼워넣은 뒤 I형 철심(1a)을 올려놓고, E형 철심(1)과 I형 철심(1a)을 용접하여 이어서 마운팅 브라켓트(6)와 I형 철심(1a)의 접촉면을 용접하여 고정한다.The secondary windings 2, the filament coils 3, the pass cores 4 and the primary windings are formed in a space composed of the side plates 8d and 8e and the upper plate 1c of the main insulating paper 8 and 8 '. 5) After inserting in turn, put the I-type iron core 1a, weld the E-type iron core 1 and the I-type iron core 1a, and then weld the contact surfaces of the mounting bracket 6 and the I-type iron core 1a. To fix it.
이때 2차권선(2)과 1차권선(5)은 별도의 절연구조를 가지지 않게되고 주절연지(8,8')의 양 옆판(8e,8d)에 의해 E형 철심(1)의 옆면(1d,1e)과 절연된다.At this time, the secondary winding (2) and the primary winding (5) does not have a separate insulating structure and the side surface of the E-type iron core (1) by the side plates (8e, 8d) of the main insulating paper (8, 8 ') ( 1d, 1e).
그리고, 2차권선(2)과 상면(1c)과는 상판(8c)에 의해 절연되고, 1차권선(5)과 I형 철심(1a)과는 바닥판(8b)에 의해 각각 절연된다.The secondary winding 2 and the upper surface 1c are insulated by the upper plate 8c, and the primary winding 5 and the I-type iron core 1a are insulated by the bottom plate 8b, respectively.
또한, 상,하로 적층되는 각 구성부재(2∼5)사이의 접촉면에는 평면상태의 별도 보조절연지를 끼워넣어 절연한다.In addition, a separate auxiliary insulating paper in a planar state is sandwiched and insulated on the contact surface between the components 2 to 5 stacked up and down.
이와같은 본 고안은 하나의 절연판재로 이루어지는 주절연지(8,8')를 이용하여 1차 및 2차권선과 철심사이를 절연할 수 있을 뿐만 아니라, 1차 및 2차권선을 제외한 기타 구성부재와 철심사이도 절연할 수 있어 절연지의 성형과정을 대폭간소화할 수 있는 효과가 있다.This invention can not only insulate between primary and secondary windings and iron cores using the main insulating paper (8,8 ') made of one insulating plate, but also other components except the primary and secondary windings. Insulation between the core and the iron core can greatly simplify the process of forming the insulating paper.
또한, 본 고안은 1차 및 2차권선과 필라멘트 코일, 패스코일등이 상, 하 접촉면만 절연지를 끼우면 상, 하부재간에 절연을 할 수 있기 때문에 절연지의 테이핑 공정을 단축할 수 있고, 이로인해 작업공정을 단순화시켜 작업자의 수를 감소시킬수 있는 작용효과가 있다.In addition, the present invention can shorten the taping process of the insulating paper because the primary and secondary windings, filament coils, pass coils, etc. can be insulated between the upper and lower members by inserting only the upper and lower contact surface. There is an effect that can reduce the number of workers by simplifying the work process.
