In the drawing, reference numeral 1 denotes a container in which a component device is stored together with an insulating gas, 2 a circuit breaker disposed outside the container 1, 3 a top terminal of the circuit breaker 2, and 4 a circuit breaker ( The lower terminal of 2), (5) is a three-phase collective connection plate attached to the circuit breaker (2), (6) is a container side conductor, (7) is an adapter, (8), (9), and (10) It's a bolt.

다음에 용기(1)와 차단기(2)를 접속할 경우에 대해 설명한다. 먼저, 차단기(2)의 위치를 조정하며, 용기(1)의 개구부(1a)에 차단기(2)의 접속판(5)을 맞추어 접속판(5)을 용기(1)에 보울트(10)에 의해 죄어 붙이고, 차단기(2)를 용기(1)에 고정한다.Next, the case where the container 1 and the circuit breaker 2 are connected is demonstrated. First, the position of the breaker 2 is adjusted and the connecting plate 5 of the breaker 2 is aligned with the opening 1a of the container 1 so that the connecting plate 5 is connected to the container 1 with the bolt 10. By tightening, and the circuit breaker 2 is fixed to the container 1.

이어서 차단기(2)의 상하단자(3), (4)에 어댑터(7)를 보울트(9)에 의해 각기 부착하고, 다시 용기측 도체(6)를 어댑터(7)에 맞추어 각기 보울트(8)에 의해 부착한다.Next, the adapters 7 are attached to the upper and lower terminals 3 and 4 of the circuit breaker 2 by bolts 9, and the container-side conductors 6 are fitted to the adapters 7, respectively. Attach by.

종래의 가스절연 개폐장치는 이상과 같이 구성되어 있으므로, 접속판(5)을 보울트로 조여 차단기(2)를 용기(1)에 고정시킨 다음, 어댑터(7)나 용기측 도체(6)를 각기 보울트로 조여 상하단자(3), (4)와 용기측도체(6)를 접속하지 않으면 안된다고 하는 접속작업이 필요한데다, 작업 공간의 확보가 필요해져, 용기내 구성기기의 배치의 제약이나 장치가 커진다는 등의 문제점이 있었다.Since the conventional gas insulated switchgear is configured as described above, the circuit breaker 2 is fixed to the container 1 by tightening the connecting plate 5 with a bowl, and then the adapter 7 or the container side conductor 6 are respectively It is necessary to connect the upper and lower terminals (3) and (4) and the container side conductor 6 by tightening with a bolt, and to secure a working space. There were problems such as getting bigger.

본원 발명은 상기와 같은 문제점을 해소하기 위해 이루어진 것으로서, 상하단자와 용기측 도체의 접속작업을 없앰으로써, 작업 공간의 확보나 용기내 기기배치의 제약을 대폭 줄이고 소형화할 수 있는 가스절연 개페장치를 얻는 것을 목적으로 하고 있다.The present invention has been made to solve the above problems, and by eliminating the connection work between the upper and lower terminals and the container-side conductor, there is provided a gas insulation opening and closing device that can significantly reduce the size of the work space and equipment constraints in the container and can be miniaturized It aims to get.

본원 발명에 의한 가스절연 개페장치는 차단기의 상하단자와 용기측 도체를 이들의 어느 한쪽에 부착한 자동연결식 단로기에 의해 접속한 것이다.The gas insulated opening and closing device according to the present invention connects the upper and lower terminals of the circuit breaker and the container-side conductor by an automatic connecting disconnector attached to either of them.

본원 발명에 있어서는 자동연결식 단로기에 의해 차단기의 상하 단자와 용기측 도체의 사이에서 약간의 치수차도 허용되므로 접속판을 용이하게 고정시키는 것으로, 도체의 접속작업이나 조정을 없앨 수 있으며, 또 작업 공간이나 용기내 기기배치의 제약도 대폭 줄일 수 있다.In the present invention, a slight dimensional difference is allowed between the upper and lower terminals of the circuit breaker and the vessel-side conductor by the automatic connecting disconnector, thereby easily fixing the connecting plate, thereby eliminating the connection work and adjustment of the conductor. Restrictions on the placement of equipment in containers can also be significantly reduced.

제1도~제3도는 본원 발명의 일실시예를 나타낸 것으로서, (1)~(5), (10)은 상기 종래 장치와 전적으로 동일한 것이다. (11)은 용기측 도체, (12)는 용기측 도체(11)의 돌출플랜지부(11a)에 기단측(基端側)을 끼워 맞추어 부착한 자동연결식 단로기이며, 원주방향으로 분할 배치되는 다수(도면에서 15개)의 동편(銅片)(12a)과 동편(12a)을 조금 느슨하게 환상(環狀)으로 묶는 3개 링형상 스프링(12b)으로 구성된다. (13)은 용기측 도체(11)에 나사맞춤한 원통형상의 금속도체이며, 단로기(12)를 피복(皮覆)하여 전계를 완화시킨다.1 to 3 show an embodiment of the present invention, wherein (1) to (5) and (10) are entirely the same as the conventional apparatus. Numeral 11 denotes a container-side conductor, and numeral 12 denotes a self-connecting disconnector in which the proximal flange 11a is fitted to the protruding flange portion 11a of the container-side conductor 11, and is divided in the circumferential direction. It consists of three ring-shaped springs 12b (15 pieces in the drawing) which are tied together in a slightly loose annular shape. (13) is a cylindrical metal conductor screwed to the vessel-side conductor 11, and covers the disconnecting device 12 to relax the electric field.

도면에 있어서, 용기(1)와 차단기(2)를 접속할 경우, 일반적으로는 차단기(2)를 상하, 좌우의 위치 조정 가능한 지그(Jig)상에 올려 놓아 밀봉처리를 하여, 접속판(5)과 용기(1)의 구멍위치를 맞추면서 접속판(5)을 용기(1)에 밀착시켜 보울트로 조인다. 그 경우, 용기측의 자동연결식 단로기(12'')는 이미 소정의 치수로 부착 고정되어 있으므로, 접속판(5)의 밀착과 함께 차단기(2)의 상하단자(3), (4)는 필연적으로 자동연결실 단로기(12'')와 맞물려 가스절연 개폐장치로서 전기회로를 형성하게 된다. 제3도는 그 조립방법의 일실시예를 입체사시도로 나타낸 것이다.In the drawing, when the container 1 and the circuit breaker 2 are connected, the circuit breaker 2 is generally placed on a jig that can be vertically positioned up and down and left and right to seal the connection plate 5. The connecting plate 5 is brought into close contact with the container 1 while being aligned with the hole position of the container 1 and tightened with a bowl. In this case, since the automatic connection disconnector 12 '' on the container side is already attached and fixed to a predetermined dimension, the upper and lower terminals 3 and 4 of the circuit breaker 2 are inevitably in contact with the connection plate 5. As a result, the electrical circuit is formed as a gas insulated switchgear by engaging with the automatic connection chamber disconnector 12 ''. Figure 3 shows an embodiment of the assembly method in a perspective view.

그리고, 상기 실시예에서는 자동연결식 단로기(12'')를 용기측 도체(11)에 부착한 것을 나타냈지만, 차단기(2)의 상하단자(3), (4)에 부착해도 좋고, 접속판(5)도 상하단자 일괄의 것이 아니라, 상부단자용과 하부단자용에 따로따로 2분할 해도 좋다. 또, 자동연결식 단로기(12'')는 둥근 형태의 것을 나타냈지만, 평각도체용(平角導體用)이나 멀티콘택트를 사용한 형상의 것이더라도 상기 실시예와 똑 같은 효과를 거둔다.And in the said Example, although it showed that the automatic connection disconnector 12 "was attached to the container side conductor 11, you may attach to the upper and lower terminals 3 and 4 of the circuit breaker 2. 5) may be divided into two parts separately for the upper terminal and the lower terminal instead of the upper and lower terminals collectively. In addition, although the automatic connection disconnector 12 '' was shown to have a round shape, the same effect as that of the above embodiment was obtained even when it was a shape used for a flat conductor or a multi contact.

이와같이, 본원 발명에 의하며, 차단기와 용기측 도체를 자동연결식 단로기로 접속했으므로, 조립 후의 접속작업을 없앨 수 있고, 용기내의 작업 공간이나 기기배치의 제약을 대폭 줄일 수 있는 동시에 또한 이것에 의해 소형화나 간략화가 가능해지며, 작업원가의 저감화를 도모할 수 있다고 하는 효과가 있다.As described above, according to the present invention, since the circuit breaker and the container-side conductor are connected by an automatic connecting disconnector, the connection work after assembling can be eliminated, and the constraints on the working space and equipment arrangement in the container can be greatly reduced, There is an effect that the simplification can be achieved and the work cost can be reduced.
