미설명부호로서, 25,25'는 가동블럭(20)을 안내하는 가이드봉을 나타내는 것이다.As unexplained reference numerals 25 and 25 'represent guide rods for guiding the movable block 20.

다음은 상기와 같이 구성되는 본 발명의 작동 및 작용에 대해 살펴보기로 한다.Next will be described the operation and action of the present invention configured as described above.

본 발명은 무정전 상태로 변압기를 교체하는 경우에 2차측 저압케이블이 연결된 연결단자와 부싱이 분리형으로 형성되어 상기 저압케이블이 연결된 연결단자(5)를 접촉된 상태로 클램핑하여 부싱에서 분리하도록 하는 것이다.According to the present invention, when the transformer is replaced in an uninterrupted state, the connecting terminal and the bushing connected to the secondary low voltage cable are formed in a separate type so that the connecting terminal 5 connected to the low voltage cable is clamped in a contact state to be separated from the bushing. .

이를 좀더 구체적으로 설명하면, 먼저 작업자는 절연 장갑을 착용하고 작업준비를 한다.In more detail, first, the worker wears insulating gloves and prepares for work.

그리고 본 발명 장치의 조임나사봉(30)을 파지하여 회전시키므로 상기 조임나사봉(30)에 나합된 가동블럭(20)이 고정블럭(20)으로 전진된 상태, 즉 좌우 접속구(41)(41')가 적절하게 벌어진 상태로 준비한다.In addition, the clamping screw rod 30 of the present invention is gripped and rotated so that the movable block 20 screwed to the screwing screw 30 is advanced to the fixed block 20, that is, the left and right connectors 41 and 41. ') Should be prepared in the proper state.

이 상태에서 상기 좌우 접속구(41)(41')의 사이가 저압케이블의 연결단자(5) 외측으로 위치하도록 위치시킨다.In this state, the left and right connecting ports 41 and 41 'are positioned so as to be located outside the connecting terminal 5 of the low voltage cable.

그리고, 상기 조임나사봉(30)을 파지하여 회전시키므로 상기 조임나사봉(30)에 나합된 가동블럭(20)이 후퇴 이동하게 된다.In addition, since the tightening screw rod 30 is gripped and rotated, the movable block 20 screwed to the tightening screw rod 30 moves backward.

이와 같은 작동은 상기 조임나사봉(30)의 선단이 고정블럭(20)에서 회전 및 지지하도록 결합 설치되어 가능하다.This operation can be coupled to the front end of the tightening screw rod 30 to rotate and support in the fixed block (20).

상기와 같이 조임나사봉(30)에 의해 가동블럭(20)이 후퇴 이동하면서 상기 가동블럭(20)의 좌우측 공간부(21)(21')에 힌지축(23)으로 결합된 작동암(31)(31')을 후방으로 인축하게 된다.As described above, the movable block 20 moves backward by the tightening screw rod 30 and is coupled to the left and right space portions 21 and 21 ′ of the movable block 20 by the hinge shaft 23. ) 31 'to the rear.

이와 같이 후퇴하는 작동암(31)(31')은 고정블럭(10)의 좌우 공간부(11)(11'), 특히 상기 공간부로 구비된 복수의 접동롤(15)(15')에 효과적으로 안내되면서 그 선단이 내측으로 오무라지는 작동을 행한다.The actuating arms 31 and 31 ′ retracted in this way are effectively applied to the left and right spaces 11 and 11 ′ of the fixed block 10, in particular, a plurality of sliding rolls 15 and 15 ′ provided to the spaces. The tip is moved inward while being guided.

이는 상기 작동암(31)(31') 선단의 접속구(41)(41')를 내측으로 오무리면서 저압케이블의 연결단자(5) 외주연을 가압하며 클램핑하는 작동을 행하게 된다.This pressurizes and clamps the outer periphery of the connecting terminal 5 of the low voltage cable while pressing the connecting ports 41 and 41 'at the tip of the operating arms 31 and 31' to the inside.

특히 상기 접속구(41)(41')내측면은 연결단자(5)의 외주연에 대응되는 곡면(42)으로 형성되어 더욱 밀착되고 견고하게 클램핑하게 되는 것이다.In particular, the inner surface of the connector (41, 41 ') is formed of a curved surface 42 corresponding to the outer periphery of the connecting terminal 5 is to be more closely and tightly clamped.

이와 같이하여 상기 접속구(41)(41')가 저압케이블의 연결단자(5)를 클램핑 완료하면, 상기 연결단자(5)가 부싱에 결합된 과정의 역순으로 연결단자를 부싱에서 인출하여 저압케이블을 분리하게 되는 것이다.In this way, when the connector (41, 41 ') is completed clamping the connection terminal 5 of the low-voltage cable, the connection terminal 5 withdraws the connection terminal from the bushing in the reverse order of the process coupled to the bushing low voltage cable Will be separated.

즉, 상기 연결단자(5)가 부싱에 압입 연결된 상태이면 상기 연결단자는 압입된 역으로 인출될 것이고, 상기 연결단자(5)가 부싱에 나사 결합된 상태이면 상기 연결단자는 나사 결합된 역으로 인출되게 될 것이다.That is, if the connection terminal 5 is press-connected to the bushing, the connection terminal will be drawn out to the press-in reversed position, and if the connection terminal 5 is screwed to the bushing, the connection terminal is screwed backward Will be withdrawn.

이와 같은 전술한 과정에 의해 상기 지상 변압기상에 연결된 저압케이블을 접속함으로서 상기 지상 변압기를 교체할 수 있게 되는 것이다.By connecting the low voltage cable connected to the ground transformer by the above-described process it is possible to replace the ground transformer.

이상에서 살펴본 바와 같이 본 발명의 지상 변압기의 저압 케이블 분리용 집게형 접속장치는 무정전 상태로 변압기 교체시에 2차측 저압케이블을 접속 상태로 분리하되, 상기 저압케이블이 연결된 연결단자가 2차측 부싱과 분리형으로 연결되어 저압 케이블의 연결단자를 집게형 접속구에 의해 접속 및 클램핑한 상태로 효과적으로 분리하므로서 안전성 및 작업성을 극대화하는 효과를 갖는 것이다.As described above, the tong type connecting device for separating the low voltage cable of the ground transformer of the present invention is uninterrupted, but when the transformer is replaced with the secondary side low voltage cable, the connecting terminal connected to the low voltage cable is connected to the secondary side bushing. It is connected in a detachable type, and effectively separates the connecting terminal of the low voltage cable in a state of being connected and clamped by a tong type connection port, thereby maximizing safety and workability.
