It is rotatably inserted into the hinge shaft 110 of the protective case 50.
이와 같이된 본 고안의 작용을 설명하면, 우선 전주(1)의 가로지지대(2)에 양측으로 고정되어 있는 현수애자(3,3a)에 전기케이블 고정본체(10)를 연결한 다음 전기케이블(4)의 피복을 일정길이로 벗겨내고 전기케이블 고정본체(10)의 전기케이블 고정홈(12)에 끼운후에 전기케이블 고정구(20)를 상부에 씌워 U볼트(16)로 고정하면 전기케이블(4)이 전기케이블 고정본체(10)에 견고하게 고정된다.Referring to the operation of the present invention as described above, first connect the electric cable fixing body 10 to the suspension insulators (3, 3a) fixed to both sides to the horizontal support (2) of the electric pole (1) and then the electric cable ( 4) Strip the sheath to a certain length and insert it into the electric cable fixing groove 12 of the electric cable fixing main body 10, and then cover the electric cable fixing fixture 20 on the upper part and fix it with the U bolt 16 to fix the electric cable (4). ) Is firmly fixed to the electric cable fixing body (10).
이 상태에서 전기케이블(4)을 상부의 애자(5)에 연결하고 타측의 전기케이블 고정본체(10)에 상기와 같은 고정방법으로 전기케이블(4)을 고정하면 되는 것이고, 이 전기케이블 고정본체(10)의 외부로는 보호케이스(40)를 걸림턱(56)과 고정구멍(48)을 이용하여 씌워 고정시키는 것이다.In this state, the electric cable 4 is connected to the insulator 5 on the upper part, and the electric cable 4 is fixed to the electric cable fixing main body 10 on the other side by the above fixing method. Outside of the (10) is to cover and secure the protective case 40 by using the locking step 56 and the fixing hole (48).
이렇게 된 상태에서 고장수리시 변전소에서 전류를 차단하게 되고 작업자는 전주에 올라가 보호케이스(50)의 일측에 형성된 개방커버(120)의 돌출고정부(124)를 일측으로 젖히게 되면 고정홈(126)이 접지고리커버(52)의 돌출턱(112)으로 부터 이탈되어 고정이 해제되고, 고정이 해제된 개방커버(120)는 자중에 의해 힌지축(110)을 중심으로 회동되어 하부방향으로 떨어지게 된다. 이 상태는 전기케이블 고정본체(10)의 접지고리(16)가 외부로 돌출된 상태가 되므로, 상기 접지고리(16)에 접지봉(30)의 접지클램프(32)를 나사결합 고정시키고, 타측의 접지봉(30a)의 접지 클램프(32a)는 접지선(6)에 연결시킨 후 작업자는 필요한 작업을 하게 되는 것이다.In this state, when the fault is repaired, the current is cut off at the substation, and the worker climbs up to the pole, and when the protrusion fixing part 124 of the open cover 120 formed at one side of the protective case 50 is flipped to one side, the fixing groove 126. ) Is released from the protruding jaw 112 of the ground ring cover 52, the fixing is released, and the fixing is released, the open cover 120 is rotated about the hinge shaft 110 by its own weight to fall in the lower direction do. In this state, since the ground ring 16 of the electric cable fixing body 10 protrudes to the outside, the ground clamp 32 of the ground rod 30 is screwed and fixed to the ground ring 16, and After the ground clamp 32a of the ground rod 30a is connected to the ground wire 6, the worker will perform the necessary work.
그런데 상기와 같이 작업중에 변전소측에서 실수로 전류를 공급할 경우에는 고압의 전류가 전기케이블(4)과 접지봉(30,30a)을 통해 접지선(6)으로 흘러 전주(1)가 뭍혀진 땅으로 흘려버리게 되므로 작업자는 고압의 전류가 변전소에서 공급되게 되도 안전하게 작업을 할 수 있는 것이다. 고장수리작업이 끝난후에는 접지고리(16)와 접지선(6)에 고정된 접지봉(30,30a)을 분리시키고 개방커버(120)를 상부 방향으로 밀어올리게 되면 개방커버(120)는 힌지부(122)를 중심으로 상부로 회동되어 상기 개방커버(120)의 돌출고정부(124)에 형성된 고정홈(126)이 접지고리커버(52)의 돌출턱(112)에 탄력고정되어 보호케이스(50)의 개방부(100)가 개방커버(120)에 의해 폐쇄되게 되며, 이 상태가 모든 작업이 끝나게 되는 것이다.However, in case of accidentally supplying current from the substation side during the operation as described above, the high voltage current flows through the electric cable 4 and the ground rods 30 and 30a to the ground wire 6 and flows to the ground where the pole 1 is plunged. Because it is discarded, the worker can safely work even if a high voltage current is supplied from the substation. After the troubleshooting work is finished, the grounding ring (16) and the grounding rod (30, 30a) fixed to the ground wire (6) is removed and the opening cover 120 is pushed upward, the opening cover 120 is hinged ( The fixing groove 126 formed in the protrusion fixing portion 124 of the opening cover 120 is rotated to an upper portion of the opening cover 120 to be elastically fixed to the protrusion jaw 112 of the ground ring cover 52 to protect the protective case 50. The open part 100 of the) is to be closed by the open cover 120, this state is to end all the work.
이와 같이 보호케이스에 작업시 보호케이스를 개방할 수 있는 돌출고정부와 고정홈을 형성시켜, 접지봉연결시 보호케이스를 개방시키지 않고도 외부에서 접지봉을 연결시키므로서, 작업이 간편하고 짧은 시간내에 안전하게 작업할 수 있는 효과를 제공하는 것이다.In this way, by forming a protrusion and a fixing groove that can open the protective case when working on the protective case, by connecting the ground rod from the outside without opening the protective case when connecting the ground rod, the operation is simple and safe work in a short time It is to provide an effect that can be done.
