본 발명은 몰드 변압기에 관한 것으로서, 상세하게는 몰드 변압기의 탭 절환기에 관한 것이다.The present invention relates to a mold transformer, and more particularly, to a tap changer of a mold transformer.

종래에는 주로 일반 유입식 변압기를 사용하여 왔으나 최근에는 도시기능의 복잡 다양화에 따라 과밀된 도시기능상 난연성, 내온성, 무공해 등의 고도의 안정성이 요구되고 또한 신뢰도가 우수한 몰드변압기의 사용이 점차 늘어나고 있으며 이는 코아부분, 권선부분, 그리고 구조지지물등로 구성되어 있다. 그리고, 권선부의 표면에는 출력 전압의 조절을 위한 탭절환기가 설치된다.Conventionally, general inflow transformers have been used, but in recent years, due to the diversification of urban functions, high density of flame retardancy, temperature resistance, pollution-free, etc. is required in overcrowded urban functions, and the use of mold transformers with excellent reliability is gradually increasing. It consists of core part, winding part, and structural support. Then, a tap changer for adjusting the output voltage is installed on the surface of the winding part.

도 1은 종래의 탭절환기를 구비한 권선부을 도시한 사시도이다.1 is a perspective view showing a winding unit having a conventional tap changer.

도시된 바와 같이 종래의 탭절환기는 권선부(1)의 표면에 설치된 다수의 탭단자(24)와, 양단이 탭단자(24)와 결합하는 탭 연결바(25)와, 탭단자(24)와 탭 연결바(25)를 보호하는 보호커버(22)로 구성된다. As shown in the drawing, a conventional tap changer includes a plurality of tab terminals 24 installed on the surface of the winding unit 1, a tab connection bar 25 at which both ends are coupled to the tab terminal 24, and a tab terminal 24. And a protective cover 22 for protecting the tab connection bar 25.

보호커버(22)는 탭단자(24)와 탭 연결바(25)의 상면에 지지금형(21)에 의해 지지된다. 즉, 지지금형(21)이 일정량 돌출되도록 형성되며, 지지금형(21)의 상면에 결합공(26)이 형성된다. 보호커버(22)는 지지금형(21)의 상면에 위치하여, 결합 볼트(23)에 의해 지지금형(21)에 결합된다.The protective cover 22 is supported by the support type 21 on the upper surface of the tab terminal 24 and the tab connecting bar 25.

도시된 바와 같이, 제 3 실시예의 탭절환기는 탭(2130)과, 커버결합부재(2150)가 스냅핏(snap-fit) 방식으로 결합되는 것을 구현한 것이다. 보호 커버(140, 141)의 구조는 제 1 실시예의 보호 커버(140, 141)의 구조와 동일하므로, 자세한 설명을 생략한다.As shown, the tap changer of the third embodiment implements that the tab 2130 and the cover coupling member 2150 are coupled in a snap-fit manner. Since the structures of the protective covers 140 and 141 are the same as those of the protective covers 140 and 141 of the first embodiment, detailed descriptions thereof will be omitted.

탭(2130)은 탭머리부(2131)와, 탭단자(110)의 암나사부에 결합되도록 탭머리부(2131)에서 돌출되어 형성된 수나사부(2132)와, 수나사부(2132)가 형성된 반대측에 커버 결합부재(2150)와 결합가능하도록 형성된 커버 결합부재 결합부(2133)로 구성된다.The tab 2130 is formed on the opposite side of the tab head portion 2131, the male screw portion 2132 protruding from the tab head portion 2131 to be coupled to the female screw portion of the tab terminal 110, and the male screw portion 2132. The cover coupling member 2150 is configured to be coupled to the cover coupling member 2133 is formed.

탭머리부(2131)는 회전을 용이하게 하기 위해서 외주가 육각으로 형성된다. 커버 결합부재 결합부(2133)는 수나사부(2132)의 반대면에 요입되어 형성되며, 내측에는 걸림턱(2134)이 형성된다.The tab head 2131 has an outer circumference formed in a hexagon to facilitate rotation.

When passing through the cover engaging member (2150) engaging jaw (2151) is expanded to be caught by the engaging jaw (2134) of the cover engaging member engaging portion 2133. Therefore, the cover coupling member 2150 may be prevented from being separated from the tab 2130.

이상에서 살펴본 바와 같은 본 발명의 실시예에 의하면 다음과 같은 사항을 포함하는 다양한 효과를 기대할 수 있다. 다만, 본 발명이 하기와 같은 효과를 모두 발휘해야 성립되는 것은 아니다.According to the embodiment of the present invention as described above, various effects including the following matters can be expected. However, the present invention is not achieved by exerting all of the following effects.

먼저, 본 발명은 커버 결합부재가 탭에 형성된 커버 결합부재 결합부에 결합되므로, 별도의 결합을 위한 부재를 구비하지 않아도 된다는 장점이 있다.First, the present invention has the advantage that the cover coupling member is coupled to the cover coupling member coupling portion formed in the tab, it is not necessary to provide a member for a separate coupling.

그 결과, 조립이 용이하며, 생산단가를 줄일 수 있다.As a result, assembly is easy and the production cost can be reduced.

이상에서는 본 발명의 바람직한 실시예를 예시적으로 설명하였으나, 본 발명의 범위는 이와 같은 특정 실시예에만 한정되는것은 아니며, 특허청구범위에 기재된 범주내에서 적절하게 변경 가능한 것이다. Although the preferred embodiments of the present invention have been described above by way of example, the scope of the present invention is not limited to these specific embodiments, and may be appropriately changed within the scope of the claims.
