본 고안은 건식 몰드 변압기의 안전장치에 관한 것으로 특히 감전사고를 미연에 방지할 수 있게 한 건식 몰드 변압기의 감전 방지장치에 관한 것이다.The present invention relates to a safety device for a dry mold transformer, and more particularly to an electric shock prevention device for a dry mold transformer that can prevent an electric shock accident in advance.

일반적인 건식 몰드 변압기는 애폭시 수지로 몰딩된 코일의 표면으로 수개의 입력 및 출력측 단자볼트가 노출되어 있고 단자 볼트가 탭 체인저(tap changer)로 연결되어 있다.Typical dry mold transformers have several input and output terminal bolts exposed to the surface of a coil molded with an epoxy resin, and terminal bolts are connected to a tap changer.

이러한 종래의 건식 몰드 변압기는 단자볼트가 노출되어 있으므로 전압을 조절하기 위하여 탭 체인저의 배열 상태를 바꾸어 연결하는 경우에는 쉽게 변환하여 연결할 수 있으나, 건식 몰드 변압기 주위에서 작업하는 경우 작업자가 건식 몰드 변압기의 노출부위에 부지불식간에 접촉되어 감전사고가 일어나는 등의 문제점이 있었으며, 이와같은 문제점을 해소하기 위하여 건식 몰드 변압기에 주위를 환기시키기 위한 위험 표지마크를 부착하고 있으나 이는 근본적인 해결책이 되지 못하는 실정이다.Since the conventional dry mold transformer is exposed to the terminal bolt, it can be easily converted and connected when connecting by changing the arrangement of the tap changer to adjust the voltage, but when working around the dry mold transformer, the operator of the dry mold transformer There was a problem such as an electric shock accident due to unintentional contact with the exposed area, in order to solve such a problem is attached a danger mark to ventilate the dry mold transformer, but this is not a fundamental solution.

본 고안은 상기한 바와같은 종래의 결함을 해소하기 위하여 안출한 것으로, 코일의 상부에 절연체인 안전커버를 씌우고, 그 안전커버를 단자볼트에 절연구조로 고정하여, 단자볼트에 접촉되어 감전되는 위험을 방지하기 위한 것인바, 이를 첨부도면에 의하여 상세히 설명하면 다음과 같다.The present invention has been devised to solve the above-mentioned conventional defects, and the safety cover which is an insulator is put on the upper part of the coil, and the safety cover is fixed to the terminal bolt with an insulating structure, and the risk of electric shock coming into contact with the terminal bolt. To prevent the bar, it will be described in detail by the accompanying drawings as follows.

제1도는 본 고안에 의한 건식 몰드 변압기의 구성을 보인 평면도이고, 제2도는 종단면도로서, 이에 도시한 바와같이 코일(4)의 상부에 단자볼트(1)를 보이지 않도록 보호하기 위한 절연체인 안전커버(5)를 복개하고, 그 안전커버(5)를 단자볼트(1)의 머리부(1')에 절연볼트(3)로 체결하여 구성한것으로, 도면에서 미설명부호 5a는 안전커버(5)에 형성한 고정공, 6은 절연와셔, 7은 탭 체인저를 보인 것이다.1 is a plan view showing the configuration of a dry mold transformer according to the present invention, Figure 2 is a longitudinal cross-sectional view, as shown therein is an insulator for protecting the terminal bolt (1) from the top of the coil (4) as shown The cover 5 is covered, and the safety cover 5 is fastened to the head 1 'of the terminal bolt 1 with an insulating bolt 3. In the drawing, reference numeral 5a denotes a safety cover 5 6 shows insulation washers and 7 shows tap changers.

제3도는 안전이중볼트의 구성을 보인 부분절결 정면도로서, 이에 도시한 바와같이, 단자볼트(1)의 머리부(1')에 탭(2)을 형성하여, 그 탭(2)에 절연볼트(3)를 체결하도록 되어 있다.3 is a partially cutaway front view showing the construction of a safety double bolt. As shown in the drawing, a tab 2 is formed on the head 1 'of the terminal bolt 1, and an insulating bolt is formed on the tab 2. (3) It is to fasten.

이와같이 된 본 고안은 변압기 사용시 정격 탭(tap)전압을 세팅시킨후 제1도 및 제2도와 같이, 코일(4)의 상부에 절연체인 안전커버(5)를 덮어 단자볼트(1)를 가린후, 안전커버(5)에 형성한 고정공(5a)에 절연와셔(6)를 개재하고 절연볼트(3)를 삽입하여 단자 볼트(1)의 머리부(1')에 형성한 탭(2) (제3도)에 체결하면, 안전커버(5)가 견고하게 고정된다.The present invention, as described above, sets the rated tap voltage when the transformer is used, and covers the terminal bolt 1 by covering the safety cover 5, which is an insulator, on the upper part of the coil 4, as shown in FIGS. 1 and 2. Tab 2 formed on the head 1 'of the terminal bolt 1 by inserting an insulating bolt 3 through an insulating washer 6 through a fixing hole 5a formed in the safety cover 5; When fastened to (FIG. 3), the safety cover 5 is firmly fixed.

이러한 본 고안은 코일(4)의 상부로 돌출된 단자볼트(1)가 안전커버(5)에 가려져 외부로 노출되지 않으므로 단자볼트(1)에 접촉되어 감전되는 문제점이 완벽하게 방지되고, 안전커버(5)를 별도의 복잡한 구성없이 단자 볼트(1)에 절연볼트(3)로 체결하는 것이므로 고정구조가 견고하면서 간단한 것이며, 절연볼트(3)와 절연와셔(6)가 안전커버(5) 외부로 돌출되어 있으나 부품 자체가 절연체이므로 감전의 위험이 없다.The present invention is because the terminal bolt (1) protruding to the upper portion of the coil (4) is covered by the safety cover (5) is not exposed to the outside, the problem that the electric shock coming in contact with the terminal bolt (1) is completely prevented, safety cover (5) is fastened to the terminal bolt (1) with an insulated bolt (3) without any complicated configuration, the fixing structure is solid and simple, the insulated bolt (3) and the washer (6) outside the safety cover (5) The parts themselves are insulators, so there is no risk of electric shock.

이상에서 설명한 바와같을 본 고안은 건식 몰드 변압기 사용시 감전의 위험을 완벽하게 방지할수 있으므로 제품의 신뢰성을 향상할 수 있고, 부수적으로 안전커버를 간단하고 견고하게 고정 할수 있는 이점이 있다.As described above, the present invention can completely prevent the risk of electric shock when using a dry mold transformer, thereby improving the reliability of the product, and additionally, there is an advantage of simply and firmly fixing the safety cover.
