Description
본 고안은 휴즈(Fuse)를 내장하여 개폐기에 부착할 수 있는 가스절연 부하 개폐기 부착형 휴즈홀더에 관한 것으로, 특히 에폭시 절연물내에 휴즈 설치공간을 확보하고 휴즈의 착탈이 가능하도록 구성된 휴즈홀더에 관한 것이다.The present invention relates to a fuse holder with a gas insulated load switch that can be attached to a switch by incorporating a fuse, and more particularly, to a fuse holder configured to secure a fuse installation space in an epoxy insulator and to attach or detach a fuse. .
일반적으로 전력회사 및 고압 수용가들은 전기제품에 의한 감전 또는 지락이나 단락등의 사고를 충분히 예방할 수 있는 제품인 가스절연 부하 개폐기를 사용하고 있으며, 이 제품은 고압 전로로 부터 사용자의 안전이 유지될 수 있도록 완전 절연 구조를 갖춘 제품이다.In general, utilities and high voltage consumers use gas-insulated load switchgear, a product that can sufficiently prevent electric shocks, ground faults, or short circuits caused by electrical appliances. This product is designed to maintain user safety from high voltage converters. It has a fully insulated structure.
상기와 같은 가스절연 부하 개폐기의 부하측 선로에는 휴즈가 장착되어 사고전류로 부터 부하측을 보호하게 되는데, 종래에는 도 1과 같이 LBS(Load Brake Switch)(도시는 생략함)의 부하측에 휴즈(1)를 장착하고 상기 휴즈의 양단을 기중에서 휴즈홀더(2)에 클램프로 고정하여 LBS 및 부하측과 선로를 구성하였다.A fuse is mounted on the load side line of the gas insulated load switch as described above to protect the load side from an accident current. Conventionally, the fuse 1 is provided on the load side of an LBS (Load Brake Switch) (not shown) as shown in FIG. And the both ends of the fuse was clamped to the fuse holder (2) in the air to form a line with the LBS and the load side.
그러나 상기와 같은 종래의 구조는 휴즈(1)의 도전부와 휴즈홀더(2) 및 단자가 외부에 그대로 노출되어 있기 때문에 인축이 접근할 경우 감전사고가 발생하게 되고, 철과 같은 도전체가 휴즈(1)나 휴즈홀더(2) 주위에 떨어졌을 때 전로의 지락 및 단락등 대형 전기사고의 위험으로 부터 자체적인 보호장치가 전혀 구비되어 있지 않다.However, in the conventional structure as described above, since the conductive part, the fuse holder 2, and the terminal of the fuse 1 are exposed to the outside, an electric shock accident occurs when the contraction approaches, and a conductor such as iron is used for the fuse ( 1) It is not equipped with its own protection device against the danger of large electric accident such as ground fault and short circuit when falling around fuse holder (2).
또한 제품 자체의 외형이 커서 많은 면적의 설치 공간이 필요한 단점도 있다.In addition, since the product itself is large in appearance, it requires a large installation space.
본 고안의 목적은 휴즈 및 휴즈홀더의 고압 도전부가 외부로 노출되는 종래의 구조와는 달리 휴즈를 절연통내에 착탈 가능하게 내장하여 인축의 감전이나 지락과 단락등의 전기사고를 예방하고 제품의 설치 면적을 축소시킬 수 있는 가스절연 주하 개폐기 부착형 휴즈홀더를 제공하기 위한 것이다.The object of the present invention is that unlike the conventional structure in which the high-voltage conductive parts of the fuse and the fuse holder are exposed to the outside, the fuse is detachably embedded in the insulation container to prevent electric shock such as electric shock, ground fault, and short circuit and to install the product. It is to provide a fuse holder with a gas insulated switchgear that can reduce the area.
상기와 같은 목적을 달성하기 위한 본 고안의 실시예에 따라 휴즈를 내장하는 절연통과, 상기 절연통의 개구부를 개폐하는 절연캡과, 상기 절연통내에 설치되어 휴즈의 일측 도전부를 고정하고 전원 인입단자가 연결되는 제1클램프와, 상기 절연캡내에 설치되어 휴즈의 일측 도전부를 고정는 제2클램프와, 상기 제2클램프에 연결된 제2통전용 단자와, 상기 절연통에 설치되어 제2통전용 단자에 전기적으로 접속되고 전원 인출단자가 연결되는 제1통전용 단자로 구성된 가스절연 부하 개폐기 부착형 휴즈홀더가 제공된다.According to an embodiment of the present invention for achieving the above object, an insulating tube with a built-in fuse, an insulating cap for opening and closing the opening of the insulating cylinder, and installed in the insulating cylinder to secure one side of the fuse and the power inlet terminal Is connected to the first clamp, a second clamp installed in the insulating cap to fix the one conductive part of the fuse, a second dedicated terminal connected to the second clamp, and a second dedicated terminal installed in the insulating tube. A fuse holder with a gas insulated load switch is provided, which is composed of a first communication terminal that is electrically connected and to which a power outlet terminal is connected.

도 2는 본 고안에 따른 휴즈홀더의 측면도와 정면도로서, 본 고안의 휴즈홀더는 에폭시로 된 절연통(11)과 상기 절연통의 개구부에 분해 결합이 가능하게 조립되는 절연캡(17)으로 구성되어 있고 휴즈는 상기 절연통(11)과 절연캡(17) 사이에 내장된다.2 is a side view and a front view of the fuse holder according to the present invention, the fuse holder of the present invention is composed of an insulating cap 11 made of epoxy and the insulating cap 17 is assembled to be disassembled and coupled to the opening of the insulating cylinder. The fuse is embedded between the insulating cylinder 11 and the insulating cap 17.
도 3은 본 고안에 따른 휴즈홀더의 조립상태 단면도로서, 절연통(11)에는 전원 인입부(12)와 전원 인출부(13)가 형성되어 있고 내부에는 휴즈(1)의 도전부 일측을 고정하는 도전성의 제1클램프(14)와 멀티 콘택트(15)가 설치되어 있으며, 일측 내주면에는 역시 도전성의 제1통전용 단자(16)가 고정되어 있다.3 is a cross-sectional view illustrating an assembled state of the fuse holder according to the present invention, in which the power supply lead 12 and the power drawer 13 are formed in the insulating cylinder 11, and one side of the conductive part of the fuse 1 is fixed therein. A conductive first clamp 14 and a multi contact 15 are provided, and a conductive first conducting terminal 16 is also fixed to one inner circumferential surface thereof.
절연캡(17)에는 상기 휴즈(1)의 반대측 일단을 고정하는 도전성의 제2클램프(18)와 통전용 링(19) 및 제2통전용 단자(20)가 고정되어 있고 상기 통전용 단자(20)는 절연통(11)의 내주면에 고정된 제1통전용 단자(16)에 접속된다.Insulating cap 17 is fixed to the conductive second clamp 18, the conductive ring 19 and the second conductive terminal 20 for fixing one end of the opposite side of the fuse (1) and the conductive terminal ( 20 is connected to the first dedicated terminal 16 fixed to the inner circumferential surface of the insulating cylinder 11.
상기 절연캡(17)은 도시되지 않은 록킹장치에 의해 절연통(11)에 분해 조립이 가능하게 조립되며, 전원 인입부(12)와 전원 인출부(13)에는 부하측 고압단자인 부싱과 절연을 유지하도록 절연고무(21)가 설치되어 있다.The insulating cap 17 is assembled to be disassembled and assembled to the insulating cylinder 11 by a locking device (not shown), and the power inlet 12 and the power outlet 13 are insulated from the bushing and the high voltage terminal on the load side. Insulating rubber 21 is provided to hold.
상기와 같이 된 본 고안의 휴즈홀더는 절연캡(17)에 설치된 제2클램프(18)에 휴즈(10)의 일측 도전부를 삽입하여 고정한 상태에서 휴즈(1)의 반대측 도전부를 절연통(11)으로 넣어 제1클램프(14)에 삽입하고 절연캡(17)을 잠금방향으로 회전시키면 절연캡(17)이 절연통(11)에 록킹되면서 휴즈의 장착이 완료된다.In the fuse holder of the present invention as described above, the conductive part opposite to the fuse 1 is inserted into and fixed to the second clamp 18 installed in the insulating cap 17. Insert it into the first clamp 14 and rotate the insulating cap 17 in the locking direction, the insulating cap 17 is locked to the insulating cylinder 11, the mounting of the fuse is completed.
상기와 같은 상태에서 절연통(11)에 설치된 전원 인입부(12)와 전원 인출부(13)를 이용하여 휴즈홀더를 가스절연 부하 개폐기에 조립하면 휴즈홀더의 설치가 완료되는데, 이때 회로의 구성은 전원 인입부(12)를 통하여 전원이 인입되고 제1클램프(14)와 일정한 점압력을 갖는 멀티 콘택트(15)를 거쳐 휴즈(1)로 인입된다.In the above state, when the fuse holder is assembled to the gas insulated load switch using the power inlet 12 and the power outlet 13 installed in the insulation cylinder 11, the installation of the fuse holder is completed. The power is introduced into the fuse 1 through the power inlet 12 and through the multi contact 15 having a constant point pressure with the first clamp 14.
휴즈(1)에 인가된 전원은 일정한 점압력을 갖는 통전용 링(19)과 제2클램프(18)를 거쳐 제2통전용 단자(20)에 인가되고 다시 제2통전용 단자(20)와 접속된 제1통전용 단자(16)와 전원 인출부(13)를 통해 최종적으로 부하측에 통전이 된다.The power applied to the fuse 1 is applied to the second communication terminal 20 via the ring 19 and the second clamp 18 having a constant point pressure, and again to the second communication terminal 20. The electricity is finally supplied to the load side through the connected first electricity supply terminal 16 and the power supply lead-out portion 13.
본 고안은 고압 도전체가 노출되어 있는 종래 휴즈장착 구조와는 달리 휴즈가 절연물로 된 절연통과 절연캡내에 내장되어 있으므로 감전이나 각종 사고전류에 의한 전기재해로 부터 인축을 보호할 수 있게된다.Unlike the conventional fuse mounting structure in which a high voltage conductor is exposed, the present invention is built in an insulation tube and an insulating cap made of an insulator, so that the human body can be protected from electric shock or electric disaster caused by various accident currents.
또한 외부에서 도전성 이물질이 접촉하여도 지락이나 단락등의 대형 사고가 발생하지 않으며, 제풍의 크기가 축소되고 전체가 절연처리되어 있기 때문에 설치면적을 축소할 수 있다.In addition, large-scale accidents such as ground faults or short circuits do not occur even when conductive foreign matter comes into contact with the outside, and the installation area can be reduced because the size of the wind is reduced and the whole is insulated.
