본 발명은 지상 변압기의 저압 케이블을 분리하기 위한 클립형 접속장치에 관한 것으로서, 특히 상기 저압 케이블이 연결된 연결단자가 2차측 부싱과 일체형으로 연결되어 저압 케이블의 단부를 클램핑하여 접속된 상태로 효과적으로 분리하기 위한 지상 변압기의 저압 케이블 분리용 클립형 접속장치에 관한 것이다.The present invention relates to a clip-type connecting device for separating the low-voltage cable of the ground transformer, in particular, the connection terminal connected to the low-voltage cable is connected integrally with the secondary side bushing to effectively separate the clamped end of the low-voltage cable in the connected state It relates to a clip-type connection device for low voltage cable separation of ground transformers.

일반적으로 지중 배전선로에는 가정이나 산업용 각종 설비 등에 전력 공급시에 발전소로부터 송전선을 통해 공급되는 22.9 KV의 특고압(1차측)을 가정이나 산업용 각종 설비에 적합한 220/380V의 저압(2차측)으로 공급하기 위하여 전압을 강하하는 수단으로 지상 변압기가 사용되고 있다.In general, underground distribution lines have 22.9 KV of extra high voltage (primary side) supplied through power transmission lines from power plants when supplying power to home and industrial facilities, etc. A ground transformer is used as a means of dropping the voltage to supply.

이러한 지상변압기는 특고압이 공급되는 1차측에는 특고압케이블의 단부에 연결된 엘보접속재가 1차측 부싱에 연결되고, 저압이 공급되는 2차측 저압케이블의 단부에 연결된 연결단자는 2차측 부싱에 연결되는 구조로 이루어진다.The ground transformer has an elbow connecting member connected to the end of the extra high voltage cable at the primary side to which the extra high pressure is supplied, connected to the primary side bushing, and a connection terminal connected to the end of the secondary low voltage cable to the low side supply is connected to the secondary side bushing. Made of structure.

이러한 변압기는 노후화나 과부하에 의하여 변압기에 이상(고장)이 발생하면 정상적으로 동작하는 변압기로 교체하여야 하는데, 이때 상기 1,2차측 부싱에서 특고압케이블과 저압케이블을 각각 분리한 형태로 변압기를 교환하게 된다.These transformers should be replaced with transformers that operate normally when an abnormality (fault) occurs in the transformer due to aging or overload. At this time, the transformers should be replaced by separating the high voltage cable and the low voltage cable from the primary and secondary bushings. do.

다시 말하여, 무정전 상태로 변압기를 교체하는 경우에 2차측 저압케이블은 수용가와 계속해서 접속된 상태로 분리하게 된다.In other words, when the transformer is replaced with an uninterrupted state, the secondary low voltage cable is disconnected while being continuously connected to the customer.

이때, 상기 저압케이블이 연결되는 2차측 연결단자는 부싱과 일체로 결합된 형태의 일체형과, 부싱에 나사식으로 결합되는 분리형으로 구분되는데, 이러한 2차측 저압케이블을 종래에는 효과적으로 접속한 상태로 안전하게 분리하기 위한 별도의 장치가 마련되어 있지 않아 안전성은 물론 작업성이 저하되는 문제점이 있었다.At this time, the secondary connection terminal to which the low voltage cable is connected is divided into an integral type of integrally coupled with the bushing, and a detachable type screwed to the bushing. Since no separate device is provided for separation, there is a problem that safety and workability are deteriorated.

본 발명은 상기한 종래 기술이 갖는 제반 문제점을 해결하고자 창출된 것으로서, 무정전 상태로 변압기 교환시에 2차측 저압케이블을 접속 상태로 분리하되, 상기 저압케이블이 연결된 연결단자가 2차측 부싱과 일체형으로 연결되어 저압 케이블의 단부만을 접속 및 클램핑한 상태로 효과적으로 분리하므로서 안전성 및 작업성을 극대화하는데 그 목적이 있다.The present invention was created to solve the above problems of the prior art, and when the transformer is replaced in an uninterrupted state, the secondary low voltage cable is disconnected in a connected state, but the connection terminal to which the low voltage cable is connected is integrally formed with the secondary side bushing. The purpose is to maximize safety and workability by effectively disconnecting only the ends of the low-voltage cable connected and clamped.

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 클립(10)의 벌어져 있는 상태로 하여 분리할 저압케이블(2)의 단부(2')를 클립(10) 사이로 삽입하여 위치하게 한다.(도 4 및 도 5 참조).Then, the end portion 2 'of the low voltage cable 2 to be separated in the open state of the clip 10 of the device of the present invention is inserted and positioned between the clips 10 (see FIGS. 4 and 5).

이와 같은 상태에서 상기 클립(10)의 일측단이 연결된 연결구(20) 및 연결케이블(25) 측을 탄발적으로 가압하여 상기 본체(50)의 착탈안내홈(54) 내로 삽입하고 상기 연결구(20)의 외주연에 형성된 지지돌기부(22)를 걸림턱부(55)에 삽입하여 걸려진 상태로 결합한다.(도 6 참조)In such a state, one side end of the clip 10 is connected to the connector 20 and the connecting cable 25 elastically and inserted into the detachable guide groove 54 of the main body 50 and the connector 20 The support protrusion 22 formed on the outer circumference of the) is inserted into the locking jaw portion 55 to be coupled in a locked state (see FIG. 6).

즉, 상기 클립(10)을 가압하여 지지 작동하면서 상기 클립(10) 사이로 삽입된 저압케이블(2)의 단부(2')를 클램핑하게 되는 것이다.That is, while pressing and supporting the clip 10, the end 2 ′ of the low voltage cable 2 inserted between the clips 10 is clamped.

이때, 상기 연결구(20)의 원형으로 형성된 지지돌기부(22)가 본체(50) 상부 일측의 "U"형 걸림턱부(55)로 전체적으로 삽입 지지되면서 저압케이블(2)을 견고하게 클램핑하게 되는 것이다.At this time, the support protrusion 22 formed in a circular shape of the connector 20 is clamped to the low-voltage cable 2 while being inserted and supported as a whole to the "U" type locking jaw portion 55 of the upper side of the main body 50. .

또한, 상기와 같은 클립(10)에 의한 저압케이블(2)의 클램링작동과 동시에 도전체로 된 상기 클립(10) 및 연결구(20)에 의해 저압케이블(2)과 연결케이블(25)이 상호 접속되는 상태로 연결되게 되는 것이다.In addition, at the same time as the clamping operation of the low-voltage cable 2 by the clip 10 as described above, the low-voltage cable 2 and the connection cable 25 are mutually connected by the clip 10 and the connector 20 made of a conductor.

이와 같이하여 저압케이블(2)의 접속 클램핑이 완료되면, 연결단자(7)에 체결볼트(8)로 체결고정된 저압케이블(2)의 단부(2')의 상기 체결볼트(8)를 해체하고 분리하여 인출함으로써, 상기 저압케이블(2)을 연결단자(7)로부터 완전 분리하게 되는 것이다.When the connection clamping of the low voltage cable 2 is completed in this manner, the fastening bolt 8 of the end 2 'of the low voltage cable 2 fastened to the connecting terminal 7 by the fastening bolt 8 is dismantled. By separating and withdrawing, the low voltage cable 2 is completely separated from the connection terminal 7.

이와 같은 전술한 과정에 의해 상기 지상 변압기(5)상에 연결된 저압케이블(2)을 접속함으로 상기 지상 변압기(5)를 교환할 수 있게 되는 것이다.By connecting the low voltage cable 2 connected on the ground transformer 5 by the above-described process, the ground transformer 5 can be replaced.

이상에서 살펴본 바와 같이 본 발명의 지상 변압기의 저압 케이블 분리용 클립형 접속장치는 무정전 상태로 변압기 교환시에 2차측 저압케이블을 접속 상태로 분리하되, 상기 저압케이블이 연결된 연결단자가 2차측 부싱과 일체형으로 연결되어 저압 케이블의 단부만을 클립에 의해 접속된 상태로 클램핑하여 효과적으로 분리함으로서 안전성 및 작업성을 극대화하는 효과를 갖는 것이다.As described above, the clip-type connection device for disconnecting the low voltage cable of the ground transformer of the present invention is disconnected from the secondary side low voltage cable when the transformer is replaced in an uninterrupted state, and the connection terminal to which the low voltage cable is connected is integrated with the secondary side bushing.
