전동차용 주변압기의 조립구조{ASSEMBLING STRUCTURE OF ELECTROMOTION VEHICLE TRANSFORMER}Assembly structure of peripheral pressure transformer for electric vehicle {ASSEMBLING STRUCTURE OF ELECTROMOTION VEHICLE TRANSFORMER}

본 발명은 전동차용 주변압기의 조립구조에 관한 것으로서, 더욱 상세하게는 전동차용 주변압기의 권선, 코어, 탱크 조립 구조에 관한 것이다. The present invention relates to an assembling structure of a peripheral pressure transformer for an electric vehicle, and more particularly, to an assembling structure of a winding, a core, and a tank of an ambient pressure for an electric vehicle.

전동차용 주변압기에 관해서는, 한국공개특허 10-2007-0104773호(이하, '선행문헌') 외에 다수 출원 및 공개되어 있다. As for the peripheral pressure transformer for electric vehicles, many applications and publications other than Korean Patent Publication No. 10-2007-0104773 (hereinafter referred to as "prior art") have been disclosed.

선행문헌에 따른 구조는, 체결구는, 상판과 하판을 갖고, 상기 상판과 하판 사이에는 방진을 위한 고무층을 갖으며, 중앙부로는 구멍이 형성되고, 하부 양측으로는 체결을 위한 나사를 갖는 방진구와; 상기 방진구 구멍을 통해 수용되며, 그 상/하부로는 체결을 위한 볼트 및 너트가 형성되고, 중간 부분은 기둥부로 형성되고, 상기 기둥부에는 플랜지부를 갖는 결속 심체로 이루어지는 것을 특징으로 한다. According to the structure according to the prior document, the fastener has an upper plate and a lower plate, between the upper plate and the lower plate has a rubber layer for dustproof, a hole is formed in the center portion, and the dustproof hole having a screw for fastening on both sides of the lower and ; It is received through the dust-proof hole, the upper and lower portions are formed with bolts and nuts for fastening, the middle portion is formed of a pillar portion, characterized in that the pillar portion is made of a binding core having a flange portion.

한편, 상기한 선행문헌을 포함한 종래의 전동차용 주변압기의 주변환장치는 도 1 에 도시된 바와 같이, 권선을 판상에 감아 단층으로 1차, 2차, 3차를 쌓아서 코어와 적층하는 방식으로 만들었으며, 탱크와 중신 조립 시 탱크 내부에 틈이 없도록 절연물과 받침목으로 빈 공간이 없도록 조립되는 방식이었다. Meanwhile, as shown in FIG. 1, the peripheral ring device of the conventional peripheral pressure transformer for an electric vehicle including the above-mentioned prior art is wound in a manner of stacking the primary, secondary, and tertiary in a single layer by laminating a winding on a plate and stacking the core with the core. In the case of assembling the tank and the middle body, it was assembled so that there is no empty space with the insulator and the supporting neck so that there is no gap inside the tank.

그러나, 이러한 방식은 권선을 단층식으로 제작하여 코어와 중신(코어+권선) 탱크 조립 방식 즉, 외함이 코어를 직접 누르는 Form fit type 으로서, 소음과 진동을 줄이는데 한계가 있었으며, 높이를 낮추는데 어려움이 있었다. However, this method is a form fit type in which the core and the core (core + winding) tank assembly method, that is, a form fit type in which the enclosure presses the core directly by manufacturing the winding in a single layer, has a limitation in reducing noise and vibration, and it is difficult to lower the height. there was.

The present invention has been made in view of the above problems, it should be less interference between the primary and secondary windings. Therefore, the primary winding is divided into two groups, and secondary windings are disposed at each primary winding. In other words, by separating and arranging the secondary windings, mutual interference can be reduced.

또한, 중신과 탱크 조립 시, 절연물과 받침목으로 고정하는 종래와 달리, 외함과 중신사이에 스프링을 장착하여, 이동 유격을 없앰으로써 구동 시 진동 및 소음을 최소화 하여야 한다. In addition, unlike the prior art that is fixed to the insulator and the support neck when assembling the body and the tank, by mounting a spring between the enclosure and the body, it should minimize the vibration and noise during driving by eliminating the movement play.

따라서, 본 발명은 권선을 2군으로 분할 배치함에 따라, 코어와 권선으로 이루어진 중신을 2군으로 분리하여 적층함으로써, 간섭을 저감시키고 주변압기의 높이를 낮추어 보다 작은 크기를 가질 수 있으며, 내부에 스프링을 장착하는 밀봉된 구조로 조립함으로써, 이동 유격을 없애고 구동 시 진동 및 소음을 줄일 수 있는 조립구조를 제공함에 그 목적이 있다. Therefore, according to the present invention, by dividing and winding the winding into two groups, by separating and stacking the core body consisting of the core and the winding into two groups, the interference can be reduced and the height of the peripheral pressure can be reduced to have a smaller size. By assembling in a sealed structure that is equipped with a spring, the object is to provide an assembly structure that can eliminate the movement play and reduce vibration and noise during driving.

또한 상기 권선은, 2군으로 분할 배치함에 따라, 상기 코어와 권선으로 이루어진 중신은 2군으로 분리하여 적층되는 것을 특징으로 한다.In addition, as the winding is divided into two groups, the core body consisting of the core and the winding is characterized in that separated into two groups are stacked.

또한 상기 코어 누름고정용 스프링은, 전후좌우로 적어도 한 개 이상 삽입되는 것을 특징으로 한다.In addition, the core pressing fixing spring is characterized in that at least one or more inserted into the front, rear, left and right.

또한 외함 조립 시, 상기 중신에 포함된 코어와 별도로, 상기 탱크 내측 전후좌우 방향으로 적어도 하나 이상의 누설 자속 감쇄용 쐐기 코어가 취부되는 것을 특징으로 한다.In addition, when assembling the enclosure, apart from the core included in the core, at least one of the wedge core for reducing the leakage flux in the front, rear, left and right directions inside the tank is mounted.

그리고 각 쌍을 이루는 쐐기 코어는, 서로 마주 보도록 취부되는 것을 특징으로 한다. The wedge cores forming each pair are mounted so as to face each other.
