전기견인 열차용 주 변압기 권선배열{WINDING ARRANGEMENT OF MAIN TRANSFORMER FOR ELECTRIC TRACTION VEHICLE}Winding main transformer winding arrangement for electric towing trains {WINDING ARRANGEMENT OF MAIN TRANSFORMER FOR ELECTRIC TRACTION VEHICLE}

본 발명은 전기견인 열차의 동력차에 추진시스템에 설치되는 주 변압기의 권선배열에 관한 것으로 각 권선간의 간섭을 최소화 하여 별도의 리액터를 사용하지 않고도 임피던스를 증가시킬 수 있도록 한 전기견인 열차용 주 변압기 권선배열에 관한 것이다. The present invention relates to a winding arrangement of a main transformer installed in a propulsion system in a power vehicle of an electric towing train. The main transformer winding for an electric towing train enables to increase the impedance without using a separate reactor by minimizing interference between each winding. It's about arrays.

일반적으로 전기견인 열차의 주 변압기는 추진시스템의 핵심장치로서 판토그라프를 통하여 고압권선에 외부 전원을 공급받아서 견인전동기 및 히터, 에어컨, 전등부하의 보조전원에 전력을 공급하는 장치이다. In general, the main transformer of the electric towing train is a core device of the propulsion system, and is a device that supplies external power to the high-voltage winding through the pantograph and supplies power to the auxiliary power of the traction motor, heater, air conditioner, and light load.

변압기의 부하측은 다수의 전력변환장치의 병렬운전을 통해 견인전동기의 속도를 제어하는 방식으로 전원이 공급되어야 하므로 다수의 권선으로 구성되며, 전력변환장치의 병렬 운전시 권선간의 전기적인 간섭을 최소화하기 위해 권선간의 임피던스가 크고 일정해야 하며, 자기결합이 최소화 되도록 제작되어야 한다. The load side of the transformer is composed of a plurality of windings because the power must be supplied in a manner that controls the speed of the traction motor through parallel operation of a plurality of power converters, to minimize the electrical interference between the windings in parallel operation of the power converters. The impedance between the windings should be large and constant, and it should be manufactured to minimize the magnetic coupling.

도 1은 일반적인 전기견인 열차용 주 변압기가 적용된 추진시스템을 보인 개념도이다. 1 is a conceptual diagram illustrating a propulsion system to which a main transformer for a general electric towing train is applied.

도 1에 개략적으로 도시한 바와 같이 전기견인 열차의 추진시스템 모듈은 한 개의 주 변압기(1)와, 두 개의 전력변환장치(5) 및 견인전동기(6) 그리고 주 변압기(1)에서 전원을 공급받을 수 있도록 하는 판토그라프(4)로 구성되어 있으며, 주 변압기(1)는 한 개의 고압권선(2) 및 4개의 저압권선(3)으로 구성되어 있다. As shown schematically in FIG. 1, a propulsion system module of an electric towing train supplies power from one main transformer 1, two power converters 5, a traction motor 6, and a main transformer 1. It consists of a pantograph (4) to receive, the main transformer (1) is composed of one high-voltage winding (2) and four low-pressure winding (3).

그리고 4개의 저압권선(3)은 두개의 전력변환장치(5)가 마련되어 두 개의 저압권선(3)이 한 개의 전력변환장치(5)와 연결되어 있으며, 두개의 전력변환장치(5)는 병렬 운전하여 각 견인전동기(6)에 전력을 공급한다. Four low-voltage windings 3 are provided with two power converters 5 so that two low-voltage windings 3 are connected with one power converter 5, and the two power converters 5 are connected in parallel. It drives and supplies electric power to each traction motor 6.

여기서 변압기에서 누설 임피던스에 가장 크게 영향을 미치는 요인은 권선의 암페어턴(Ampere-turn)의 분포와 더불어 두 권선간의 치수이다. The biggest factor affecting the leakage impedance in a transformer is the distribution of ampere-turns in the windings and the dimensions between the two windings.

이때 두 권선간의 치수는 누설자속 통로라고 불리는 내,외부 권선사이의 통로, 권선의 높이 및 권선 폭이 주 변압기의 임피던스에 가장 큰 영향을 주는 요소이다. At this time, the dimension between the two windings is a factor between the inner and outer windings, the leakage height, and the winding height and the winding width.

하지만 주변압기는 치수의 제한을 받으므로 반경방향의 주 누설자속 통로를 이용하여 임피던스를 증가시키는데 한계가 있다. However, since the peripheral pressure is limited in dimensions, there is a limit to increase the impedance by using the radial main leakage flux path.

도 2는 종래의 전기견인 열차용 주 변압기 권선배열을 보인 구성도이다. Figure 2 is a block diagram showing a winding arrangement of the main transformer for the conventional electric towing train.

그리고 종래의 주변압기(1)를 도시한 도 2에 도시한 바와 같이 고압권선(2) 및 다수의 저압권선간(3)의 임피던스를 일정하게 하기 위해 내외측 저압권선을 전위시켜 물리적인 거리를 동일하게 구성하였다. As shown in FIG. 2, which shows a conventional peripheral pressure transformer 1, in order to make the impedance between the high voltage winding 2 and the plurality of low voltage windings 3 constant, the inner and outer low voltage windings are displaced to physical distance. Same configuration.

그러나 권선고가 크고, 권선간의 거리가 작아 임피던스가 작으므로 권선간의 임피던스를 증가시키기 위해 리액터(7)를 저압권선에 설치하여 임피던스를 증가시 켰으나, 변압기 내부에 주 권선 이외에 다수의 리액터(7)를 설치해야 하므로 변압기의 내부 구조가 복잡해지는 단점이 있다. However, because the winding height is large and the distance between the windings is small, the impedance is small. Therefore, in order to increase the impedance between the windings, the reactor 7 is installed in the low voltage winding to increase the impedance. There is a disadvantage that the internal structure of the transformer is complicated to install.

본 고안은 상기의 필요성을 감안하여 창출된 것으로서, 각 권선간의 간섭을 최소화 하여 별도의 리액터를 사용하지 않고도 임피던스를 증가시킬 수 있도록 한 전기견인 열차용 주 변압기 권선배열을 제공하는 것을 그 목적으로 한다.The present invention was created in view of the above necessity, and an object thereof is to provide a main transformer winding arrangement for an electric towing train that minimizes interference between each winding and increases impedance without using a separate reactor. .

상기의 목적을 달성하기 위한 본 고안의 전기견인 열차용 주 변압기 권선배열은 전기추진 열차에 탑재되어 견인전동기 및 각종 보조기기에 전원을 공급하는 주변압기에 있어서, 저압권선의 높이를 줄이고, 내부 누설 임피던스를 최대로 이용하기 위하여 권선을 2층(Double Tier)으로 구성하며, 병렬 연결되는 복수의 고압권선과, 상기 고압권선에 각각 배열되는 저압권선이 하나의 쌍으로 배열되는 것을 특징으로 한다. The main transformer winding arrangement of the electric towing train of the present invention for achieving the above object is mounted on the electric propulsion train to supply power to the traction motor and various auxiliary equipment, reducing the height of the low-voltage winding, internal leakage The winding is configured in two layers to maximize the impedance, and a plurality of high voltage windings connected in parallel and low voltage windings respectively arranged on the high voltage winding are arranged in a pair.

상술한 바와 같이 고압권선과 저압권선이 하나의 쌍을 이루고, 각각의 쌍을 병렬 연결되도록 한 전기견인 열차용 주 변압기 권선배열은 각 권선간의 간섭을 최소화 하여 별도의 리액터를 사용하지 않고도 임피던스를 증가시킬 수 있는 효과가 있다.As described above, the main transformer winding arrangement of the electric towing train, in which a high-voltage winding and a low-voltage winding form a pair and each pair is connected in parallel, minimizes the interference between the windings and increases impedance without using a separate reactor. It can be effected.

이하 첨부된 도면을 참조하면서 본 고안에 따른 바람직한 실시예를 상세히 설명하기로 한다. Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 고안을 설명함에 있어서, 정의되는 용어들은 본 고안에서의 기능을 고려하여 정의 내려진 것으로, 본 고안의 기술적 구성요소를 한정하는 의미로 이해되어서는 아니 될 것이다.In the description of the present invention, terms defined are defined in consideration of functions in the present invention, it should not be understood as a meaning limiting the technical components of the present invention.

도 3은 본 고안의 일실시예에 따른 전기견인 열차용 주 변압기 권선배열을 보인 구성도이다. Figure 3 is a block diagram showing the winding arrangement of the main transformer for the electric towing train according to an embodiment of the present invention.

도 3을 참조하여 설명하면, 본 고안의 일실시예에 따른 전기견인 열차용 주 변압기(100) 권선배열은 적어도 하나 이상의 복수로 병렬 연결되는 고압권선(10)과, 상기 고압권선(10)에 각각 배열되는 저압권선(20)으로 구성된다. Referring to FIG. 3, the winding arrangement of the main tow train main transformer 100 according to an embodiment of the present invention includes a high voltage winding 10 connected in parallel to at least one of the plurality of high voltage windings, and the high voltage winding 10. It consists of the low pressure windings 20 arrange | positioned respectively.

이때 고압권선(10)은 저압권선(20)과 쌍을 이룰 수 있도록 분리하며 병렬연결 되며, 각각의 고압권선(10)은 병렬 연결하되 도시한 바와 같이 각각의 고압권선에 각각의 저압권선(20)이 설치된다. At this time, the high-voltage winding 10 is separated in parallel to be paired with the low-voltage winding 20 and connected in parallel, each of the high-voltage winding 10 is connected in parallel, as shown in each of the low-voltage winding (20) ) Is installed.

즉, 제1고압권선(11)에는 제1저압권선(21)이 배열되고, 제2고압권선(12)에는 제2저압권선(22)이 배열된다. 제3고압권선(13)에는 제3저압권선(23)이 배열되며, 제4고압권선(14)에는 제4저압권선(24)이 배열된다. That is, the first low pressure winding 21 is arranged in the first high pressure winding 11, and the second low pressure winding 22 is arranged in the second high pressure winding 12. A third low pressure winding 23 is arranged in the third high pressure winding 13, and a fourth low pressure winding 24 is arranged in the fourth high pressure winding 14.

그리고 저압권선(20)을 2층(Double Tier)으로 구성하여 권선의 높이를 줄이는 방식으로 고압권선(10)과 임피던스를 증가시킨다. 따라서 제한된 공간 내에서 높은 임피던스를 얻을 수 있고, 자기결합을 최소화 시킬 수 있다. In addition, the low-voltage winding 20 is configured in two layers (double tier) to increase the high-voltage winding 10 and the impedance in a manner of reducing the height of the winding. Therefore, high impedance can be obtained in a limited space and magnetic coupling can be minimized.

이때 고압권선(10)은 저압권선(20)과 쌍을 이룰 수 있도록 분리하며 병렬연결 되어야한다. 이렇게 고압권선(10)은 저압권선(20)과 각각 쌍으로 분리하여 병렬연결 구성하므로 저압권선(20)과 고압권선간(10)의 물리적인 거리가 일정하므로 임 피던스도 일정하다. At this time, the high-voltage winding 10 should be separated in parallel to be paired with the low-voltage winding (20). Thus, the high-voltage winding 10 is separated into a pair of low-voltage winding (20), respectively configured in parallel connection, so the physical distance between the low-voltage winding 20 and the high-voltage winding (10) is constant, so the impedance is also constant.

또한, 상기와 같이 구성할 경우 저압권선(20)간의 임피던스는 고압권선(10) 및 저압권선(20) 임피던스의 두 배 정도로 증가하므로 권선간의 간섭도 줄일 수 있다. In addition, when configured as described above, the impedance between the low voltage windings 20 is increased by about twice the impedance of the high voltage windings 10 and the low pressure windings 20, so that the interference between the windings can be reduced.

이상에서 본 고안의 전기견인 열차용 주 변압기 권선배열에 대한 기술사상을 첨부도면과 함께 서술하였지만, 이는 본 고안의 가장 양호한 실시 예를 예시적으로 설명한 것이지 본 고안을 한정하는 것은 아니다. Although the technical idea of the main transformer winding arrangement for the electric towing train of the present invention has been described with the accompanying drawings, this is illustrative of the best embodiment of the present invention and is not intended to limit the present invention.

따라서 이 기술분야의 통상의 지식을 가진 자이면 누구나 본 고안의 기술사상의 범위를 이탈하지 않는 범위 내에서 치수 및 모양 그리고 구조 등의 다양한 변형 및 모방할 수 있음은 명백한 사실이며 이러한 변형 및 모방은 본 고안의 기술 사상의 범위에 포함된다. Therefore, it is obvious that anyone with ordinary skill in the art can make various modifications and imitations such as dimensions, shapes, structures, etc. without departing from the scope of the technical idea of the present invention.
