Description
본 발명은 권철심 방식의 변압기(transformer)를 제공하기 위한 것으로, 특히 3상 3각의 권철심 변압기를 제조함에 있어 무부하 손실과 여자전류의 감소 그리고 철심제작공정의 단축과 원가절감 및 경량화와 제품 외형의 축소 등을 수반케하여 저 손실, 저 소음 및 고 효율성을 도모하는 3상 3각 권철심 변압기의 제조방법에 관한 것이다.The present invention is to provide a transformer of the core winding method, in particular, in the manufacture of a three-phase three-angle winding iron core transformer, no-load loss, reducing the excitation current, shortening the iron core manufacturing process, cost reduction, light weight and products The present invention relates to a method for manufacturing a three-phase triangular wound core transformer with low loss, low noise, and high efficiency, accompanied by a reduction in appearance.
일반적으로, 변압기란 전자유도작용을 이용하여 교류전압이나 전류의 값을바꾸는 정지기(靜止器인)인데, 전력용 변압기는 변압기로 교류회로에 가해지는 어떤 전압을 그보다 높이거나 혹은 낮은 전압으로 변화시킬 수 있으며 전력은 변하지 아니한 특성을 갖는다.In general, a transformer is a stopper that changes the value of an AC voltage or an electric current by using an electromagnetic induction action. A power transformer is a transformer that changes a voltage applied to an AC circuit to a higher or lower voltage. And power has the same characteristic.
이와 같은 변압기는 전원에 연결하는 1차 권선과 부하에 연결하는 2차 권선은 같은 철심 위에 감겨져있으며, 철심은 두께가 0.35㎜인 규소강판이나 퍼멀로이, 페라이트 등의 자성재료를 포개서 필요한 두께로 조립된다.In such a transformer, the primary winding connected to the power supply and the secondary winding connected to the load are wound on the same iron core, and the core is assembled to the required thickness by overlapping magnetic materials such as silicon steel sheet, permalloy, and ferrite, which are 0.35 mm thick. .
변압기의 실제 구조는 용량이나 전압에 따라서 다양한 것이나 중요 부분은 권선과 철심이며, 이것을 탱크 안에 넣고 절연내력을 증가시키고, 철심이나 권선에서 발생하는 열을 기름의 대류나 복사에 의해 방열시키기 위해 절연유로 가득채워주게 된다.The actual structure of the transformer varies depending on the capacity and voltage, but the important parts are the windings and the iron core, which are put into the tank to increase the dielectric strength, and to insulate the heat generated from the iron core or the winding by oil convection or radiation. It is filled up.
본 발명이 적용되는 3상식의 중·대용량 변압기는 3상의 1차 및 2차 코일을 모두 탱크 속에 설치한 것으로 단상변압기 3대의 효과가 있다.The three-phase medium- and large-capacity transformer to which the present invention is applied has three-phase primary and secondary coils installed in a tank, which has the effect of three single-phase transformers.
특히, 본 발명이 채택하고 있는 권철심 변압기는 배전용으로 널리 사용되고 있으며, 철심의 구성은 얇은 규소강판을 사용하지 않고 띠 모양으로 기다란 규소띠강을 테이프 감듯 필요한 단면적이 될 때까지 성층하는 것으로 강판을 포개 성층하는 것보다 철심에서의 손실이나 무부하때의 전류도 적다는 특성을 갖는다.In particular, the coil core transformer adopted by the present invention is widely used for power distribution, and the structure of the iron core is not to use a thin silicon steel sheet, but to form a steel sheet by laminating it until the required cross-sectional area is obtained by winding an elongated silicon strip steel in a strip shape. It has a characteristic that there is less current loss and no current in iron core than lamination.
반면, 종래의 일반화된 3상 배전용 변압기(특히, 중·소용량으로 500㎸급 이하)는 적철심의 가공방식을 이용하는 것으로, 철심의 요크(YOKE), 렉(LEG)부분을 별도로 절단(CUTTING)하여 각각 교차 적응시키는 방식을 적용하는데, 철심의 이음부위 부분으로 인한 자속밀도의 증가에 따라서 소음이 발생하거나 손실이 증가되는원인 등을 제공하였고, 과다한 철손의 ALC를 줄이기 위하여 고가의 규소강판을 사용함으로서 재료비가 현저하게 증가하거나 생산 제조시 발생하는 복잡한 작업 공정으로 제작이 매우 까다로우며, 인건비의 상승에 따라 결국 제품 단가가 상승하게 되어 효율성이 낮다는 문제점을 수반하고 있다.On the other hand, conventional generalized three-phase power distribution transformers (especially medium and small capacity of 500㎸ or less) use a red core processing method, and separately cut the yoke and leg portions of the iron core. Cross-adaptation method is applied, which provides the cause of noise or loss due to the increase of magnetic flux density due to the joint part of the iron core, and the use of expensive silicon steel sheet to reduce the ALC of excessive iron loss. By using it, the production cost is very demanding due to the remarkable increase in material cost or the complicated work process that occurs during production and manufacturing, and the labor cost increases, resulting in low product cost, resulting in low efficiency.
또한, 외함의 사이즈가 커져 설치 및 운반시의 번거러움을 야기한다.In addition, the size of the enclosure is increased, causing trouble during installation and transportation.
따라서, 상기의 제반 문제점을 해결하기 위해 본 발명은 특히 3상 500㎸급 이하 배전용 변압기를 그 적용 대상으로 하되, 종래의 적철심 방식을 권철심 형식으로 변환하여 수전된 전압을 수용가에서 필요로 하는 전압으로 변경하여 전력이 공급되도록 한 것으로 무부하 손실의 상대적 감소와 여자전류의 감소 또한 철심제작공정의 단축 및 원가절감과 경량화 그리고 제품 외형의 사이즈 축소를 가능케 함으로 저 손실, 저 소음 및 고 효율로 양질의 전원공급 및 설치 이동시의 유용함이 구현되도록 함에 그 안출된 목적이 있다.Therefore, in order to solve the above problems, the present invention is particularly applicable to the three-phase 500 kW or less power distribution transformer, the conventional hematite core system to convert the winding core type to receive the received voltage at the customer It is designed to supply electric power by changing the voltage to the nominal voltage, and to reduce the relative loss of no-load loss and excitation current, and also to reduce the core manufacturing process, reduce the cost, light weight, and reduce the size of the product. Its purpose is to ensure that a good power supply and utility of the installation movement is implemented.

상기의 목적을 달성하기 위하여 본 발명은 3상 배전용 변압기에 적용되어 3상 3각의 권철심 변압기를 제조하기 위해 규소강판을 일정한 두께 폭이 유지되도록 환형상으로 권회시키는 단계; 상기 환형 상태의 권회된 권철심이 이송수단을 통해 가공위치로 이동되도록 한 단계; 상기 이동된 권철심의 외주면을 프레스로 가압하여 직사각형태를 유지케 한 후 밴드로 결속하는 단계; 상기 각각의 단계를 거쳐 밴드 결속된 2개의 권철심이 프레스로 가압하기 이전의 환형 상태로 확대 권회된 또다른 권철심의 내공간부에 삽입되도록 환형 상태의 권철심 외주연을 다소 가압시키어 약 4각형의 외형으로 형성시켜주는 단계; 상기 내삽이 완료된 이후 4각형의 외주면을 프레스로 긴밀하게 가압하여 내삽된 권철심과 일체화 한 후 밴드로 결속하는 단계; 및 이후 코일 권선의 단계를 구비하여 3상 500㎸급 이하의 배전용 변압기가 제조되도록 함을 특징으로 한다.In order to achieve the above object, the present invention is applied to a three-phase power distribution transformer winding the silicon steel sheet in an annular shape so as to maintain a constant thickness width to produce a three-phase triangular winding core transformer; Causing the wound coil core of the annular state to be moved to a machining position through a conveying means; Pressing the outer circumferential surface of the wound winding core by a press to maintain a rectangular shape and then binding the band by a band; Through the respective steps, the band-wound two cores of the band are pressed into the inner space part of another wound core that is expanded and wound into the annular state before pressing by the press, and presses the outer periphery of the core of the annular state slightly to form a quadrilateral. Forming an outer shape; After the interpolation is completed, tightly pressurizing the outer circumferential surface of the square with a press to integrate the interleaved coil core and to bind the band; And then it has a step of winding the coil characterized in that to produce a three-phase 500 kW or less distribution transformer.
이하, 첨부 도면을 참조하여 본 발명의 바람직한 실시예를 보다 구체적으로 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
첨부된 도 1은 본 발명 제조방법의 일 단계를 주변의 구조물과 같이 도시한 평면도이고, 도 2의 (A)(B)(C)(D)는 각각의 제조과정을 도시한 예시도이다.1 is a plan view showing one step of the manufacturing method of the present invention as the surrounding structure, Figure 2 (A) (B) (C) (D) is an exemplary view showing each manufacturing process.
먼저, 본 발명의 3상 배전용 변압기를 구현하기 위해서는 코어(CORE) 가공용으로 PH06의 규소강판(1)이 제공되어야 하며 0.29×150(100㎸A)의 규격을 만족시켜야 한다.First, in order to implement the three-phase distribution transformer of the present invention, the silicon steel sheet 1 of PH06 should be provided for core processing and should satisfy the specification of 0.29 × 150 (100 kA).
상기한 규소강판(1)을 이용하여 소정의 일정한 두께 폭이 유지될 수 있도록 복수 층으로 긴밀하게 권회함으로 환형의 도우넛 형상이 유지되도록 한 제조 단계를 마련하여 3개의 권철심(10)(20)(30)이 각각 제조되도록 한다.Three winding cores (10, 20) by using the silicon steel sheet (1) by providing a manufacturing step to maintain an annular doughnut shape by winding tightly in a plurality of layers so that a predetermined constant thickness width can be maintained Let each 30 be manufactured.
이때, 상기 3개의 권철심(10)(20)(30)중 2개의 권철심(20)(30)은 나머지 권철심(10)보다 다소 축소된 사이즈의 직경 및 내경이 유지되도록 하되, 그 두께 폭은 상호간 동일함이 요구된다.At this time, the two coil cores 20, 30 of the three coil cores 10, 20, 30 to maintain the diameter and inner diameter of the somewhat reduced size than the remaining coil core 10, the thickness The widths are required to be equal to each other.
이후, 전술한 축소된 직경의 권철심(20)(30)은 별도의 이송수단 예컨대, 로울러 컨베이어 시스템(2)을 이용하여 프레스 등의 형틀(3)이 마련되어 있는 가공위치로 이동되도록 한 단계를 거친 후 다음 단계로 상기 이동된 각 권철심(20)(30)의 4각 외주면을 프레스로 가압하여 직사각형태를 유지케하고 형태의 항상성을 유지하기 위해 금속재의 밴드(4)로 견고하게 결속 처리한다.Thereafter, the above-described reduced diameter winding cores 20 and 30 are moved to a processing position where the mold 3 such as a press is provided by using a separate conveying means, for example, a roller conveyor system 2. After roughing, the four-sided outer circumferential surface of each of the wound cores 20 and 30 moved to the next step by a press to maintain a rectangular shape and firmly bind with a metal band 4 to maintain homeostasis in form. do.
이후, 상기 각각의 단계를 거쳐 밴드 처리된 2개의 권철심(20)(30)은 역시 로울러 컨베이어 시스템(2)을 통해 가공위치에 놓여져 대기중인 나머지 확대된 직경의 권철심(10) 내공간부 상단으로부터 삽입이 이루어지도록 하는데, 환형 상태로는 2개의 권철심(20)(30)이 내삽되기 곤란함으로 용이한 삽입을 위해 권철심(10) 4면의 외주면을 프레스 형틀(3)로 다소 가압시키어 약 4각형의 단면적 외형을 유지시키는 단계가 마련된다.Subsequently, the two winding cores 20 and 30 banded through the respective steps are placed in the machining position through the roller conveyor system 2 and the upper portion of the inner space of the winding core 10 having the remaining enlarged diameter in the air. Insertion is to be made from, but in the annular state of the two winding cores (20, 30) is difficult to interpolate, for easy insertion, the outer circumferential surface of the four sides of the winding core (10) to press the mold 3 slightly A step is provided to maintain an approximately square cross-sectional shape.
상기의 단계를 거쳐 내삽이 완료되면, 이후 다음 단계로 권철심(10)의 내주면과 내삽된 권철심(20)(30)의 외주면이 상호 밀착될 수 있도록(공간부의 형성이 최소화 되도록) 4각의 외주면을 긴밀하게 가압시키어 전체적으로 4각의 평면 형상을 구현한 후 각 권철심(10)(20)(30)이 일체화되게 밴드(4)로 견고하게 결속 처리하는 것이며, 코일 권선의 단계 이후에 스테인레스 외함으로 봉지하여 장기간의 안정적인 사용보장과 쇼트의 위험으로부터 벗어나도록 한다.When the interpolation is completed through the above steps, the next step to the next step so that the inner circumferential surface of the iron core 10 and the outer circumferential surface of the interpolated coil core 20, 30 can be in close contact with each other (to minimize the formation of the space portion) After tightly pressing the outer circumferential surface of the square to realize a quadrangular shape as a whole, each winding core 10, 20, 30 is integrally treated with the band 4 so as to be integrated, and after the coil winding step Encapsulated in a stainless steel enclosure to ensure long-term stable use and to avoid the risk of short circuit.
이와 같은 권철형 제조 방식의 본 발명은 철손의 감소에 의한 철심 단면적을 줄일 수 있을 뿐만 아니라 이로 인하여 권선의 길이도 줄게됨으로 부하손실이 감소된다는 효과를 얻게된다.The present invention of the wound iron-type manufacturing method can reduce the core cross-sectional area due to the reduction of the iron loss, thereby reducing the length of the winding is obtained the effect that the load loss is reduced.
권선의 저항 R = ρResistance of the winding R = ρ
여기서, ρ : 저항율, ι: 도체의 길이, S : 도체의 단면적Where ρ is the resistivity, ι is the length of the conductor, S is the cross-sectional area of the conductor.
e값이 줄어들어 도체 손실이 줄어들게 된다.The value of e decreases, resulting in reduced conductor losses.
때문에, 본 발명은 동손 및 철심 적층 공정의 단순화에 기인하여 생산 원가를 절감할 수 있으며, 변압기의 특성을 우수하게 할 수 있다.Therefore, the present invention can reduce the production cost due to simplification of copper loss and iron core lamination process, and can improve the characteristics of the transformer.
예컨대, 적철심과의 비교를 통한 철손의 감소치는 무려 18.5%에 이른다는 것으로 즉, 3상 100㎸A 적철심의 시험치는 570Ｗ인 반면, 3상 100㎸A 권철심의 설계치는 465Ｗ로서, (105/570)×100 ≒ 18.5%가 감소되는 효과를 수반한다.For example, the reduction of iron loss through comparison with hematite core reaches 18.5%, that is, the test value of three-phase 100㎸A hematite core is 570Ｗ, while the design value of three-phase 100㎸A winding iron core is 465 ,, (105 / 570) × 100 μs with an effect of decreasing 18.5%.
따라서, 본 발명은 철심을 소둔하여 자속의 방향을 일정하게 하고, 철심의 이음 부위에서 발생할 수 있는 손실을 최소화하여 효율을 극대화함은 물론 변압기의 소형화와 소음의 감소로 환경 친화적 성격을 유지하게 된다.Therefore, the present invention maintains the environmentally friendly characteristics by minimizing the loss that can occur in the direction of the magnetic flux by annealing the iron core, minimizing the loss that can occur in the joint portion of the iron core, as well as miniaturization of the transformer and noise reduction .
아울러, 본 발명은 향후 몰드 변압기, 건식 변압기 및 리액터의 철심에도 적용 가능함은 물론이다.In addition, the present invention is, of course, applicable to the core of the mold transformer, dry transformer and reactor in the future.
