도 1 내지 도 8을 참조하면, 본 발명의 일 실시예에 따른 접지선이 매립된 전주장치(1)는 전주(100)와 마개부(200)를 포함한다. 전주(100)는 원통형상으로 대지(40)에 높이방향으로 설치된다. 전주(100)는 내부에 가공지선(10)과 연결된 접지선(21)이 위치된다. 구체적으로, 접지부(20)는 접지선(21), 접지동봉(22)을 포함한다. 접지선(21)은 전주(100)의 인입홀부(110)로 인입되어 전주(100)의 공간부(140)를 통과하여 전주(100)의 인출홀부(120)로 인출된다. 접지동봉(22)은 접지선(21)과 연결되고, 접지선(21)과 함께 대지(40)에 매설된다. Referring to FIGS. 1 to 8 , an electric pole 1 in which a ground wire is embedded according to an embodiment of the present invention includes an electric pole 100 and a stopper 200. Electric pole 100 has a cylindrical shape and is installed in the height direction on the ground 40. The electric pole 100 has a ground wire 21 connected to the processing branch line 10 therein. Specifically, the ground portion 20 includes a ground wire 21 and a ground copper bar 22 . The ground wire 21 is drawn into the lead-in hole 110 of the pole 100 and is drawn out through the space 140 of the pole 100 and into the lead-out hole 120 of the pole 100. The ground copper rod 22 is connected to the ground wire 21 and is buried in the ground 40 together with the ground wire 21 .

보강접지부(30)는 보강접지선(31)과 보강접지동봉(32)을 포함한다. 보강접지선(31)은 접지선(21)과 결합되어 접지선(21)을 보강한다. 보강접지동봉(32)은 보강접지선(31)과 연결되고, 보강접지선(31)과 함께 대지(40)에 매설된다. The reinforcing grounding portion 30 includes a reinforcing grounding wire 31 and a reinforcing grounding rod 32. The reinforcement ground line 31 is combined with the ground line 21 to reinforce the ground line 21 . The reinforcing ground rod 32 is connected to the reinforcing ground line 31 and is buried in the earth 40 together with the reinforcing ground line 31.

전주(100)는 인입홀부(110), 인출홀부(120) 및 출입홀부(130)를 구비한다. 인입홀부(110)에는 가공지선(10)과 연결되는 접지선(21)이 인입된다. 인입홀부(110)에 인입된 접지선(21)은 전주(100)의 공간부(140)를 통과하여, 인출홀부(120)로 인출된다. The electric pole 100 has an inlet hole 110, a withdrawal hole 120 and an entrance hole 130. A ground wire 21 connected to the processing branch line 10 is introduced into the lead-in hole 110 . The ground wire 21 drawn into the lead-in hole 110 passes through the space 140 of the electric pole 100 and is drawn out to the lead-out hole 120 .

인출홀부(120)는 인입홀부(110)와 이격되게 배치되고, 접지선(21)이 인출된다. 인출홀부(120)는 대지(40)에 매설된 상태가 된다.The lead-out hole 120 is disposed to be spaced apart from the lead-out hole 110, and the ground wire 21 is drawn out. The withdrawal hole 120 is buried in the land 40.

출입홀부(130)는 인입홀부(110) 및 인출홀부(120) 사이에 배치되고, 접지선(21)이 출입가능하다. 출입홀부(130)는 대지(40)로부터 설정높이에 이격된 위치에 위치된다. 이때, 설정높이는 0.5m가 바람직하다. 이로 인해, 지상에서 쉽게 작업을 진행할 수 있다. 만약, 설정높이가 0.5m 미만이거나 초과되는 경우 접지선(21)을 인출하기가 어려운 문제점이 있다.The access hole 130 is disposed between the lead-in hole 110 and the lead-out hole 120, and the ground wire 21 is accessible. The entrance hole 130 is located at a position spaced apart from the site 40 at a set height. At this time, the set height is preferably 0.5 m. Due to this, the work can be easily performed on the ground. If the set height is less than or exceeds 0.5 m, there is a problem in that it is difficult to withdraw the ground wire 21 .

출입홀부(130)는 접지선(21)의 접지여유선(21a)이 출입된다. 이와 같이, 출입홀부(130)를 통해 접지선(21)의 접지여유선(21a)을 인출한다. 이때, 접지여유선(21a)은 설정길이를 가지며, 측정기(50)가 설치되거나, 보강접지선(23)이 결합될 수 있다. 이때, 설정길이는 0.3m가 바람직하다. 이로 인해, 작업자가 접지여유선(21a)에 측정기(50)를 설치하여 접지선(21)의 접지저항값을 측정하거나 접지선(21)에 보강접지선(23)을 결합하기가 쉬울 수 있다. 이때, 측정기(50)는 hook on 방식으로 접지선(21)의 접지저항값을 측정한다. 따라서, 고소작업차에 승주하여 접지선(21)의 접지저항값을 측정하는 종래의 기술에 비해 지상에서 접지선(21)의 접지저항값을 측정할 수 있어 보다 안정적으로 작업을 수행할 수 있다. The ground clearance line 21a of the ground line 21 enters and leaves the entrance hole 130 . In this way, the ground margin line 21a of the ground line 21 is drawn out through the entrance hole 130 . At this time, the ground clearance line 21a has a set length, and the measuring device 50 may be installed or the reinforcement ground line 23 may be coupled. At this time, the setting length is preferably 0.3m. For this reason, it may be easy for a worker to install the measuring device 50 on the ground margin line 21a to measure the ground resistance value of the ground line 21 or to couple the reinforcement ground line 23 to the ground line 21. At this time, the measuring device 50 measures the ground resistance value of the ground wire 21 in a hook-on manner. Therefore, it is possible to measure the ground resistance value of the ground wire 21 on the ground compared to the conventional technique of measuring the ground resistance value of the ground wire 21 by riding on a high-altitude work vehicle, so that the work can be performed more stably.

만약, 설정길이가 0.3m 미만이거나 초과되는 경우 작업자가 접지여유선(21a)에 측정기(50)를 설치하여 접지선(21)의 접지저항값을 측정하거나 접지선(21)에 보강접지선(23)을 결합하기 어려울 수 있다. If the set length is less than or exceeds 0.3 m, the operator installs the measuring device 50 on the ground margin line 21a to measure the ground resistance value of the ground line 21 or connects the reinforcement ground line 23 to the ground line 21. Can be difficult to combine.

마개부(200)는 출입홀부(130)에 결합되며, 출입홀부(130)를 폐쇄한다. 마개부(200)는 출입홀부(130)에 결합되어 출입홀부(130)를 폐쇄하여, 출입홀부(130)가 외부로 노출되는 것을 방지한다. 이로 인해, 출입홀부(130)로부터 이물질이 유입되는 것을 막을 수 있다. The stopper 200 is coupled to the entrance hole 130 and closes the entrance hole 130 . The stopper 200 is coupled to the entrance hole 130 to close the entrance hole 130, thereby preventing the entrance hole 130 from being exposed to the outside. Due to this, it is possible to prevent foreign substances from entering through the entrance hole 130 .

마개부(200)는 탄성재질을 포함하여 이루어지고, 탄성복원력에 의해 출입홀부(130)에 끼움결합된다. 마개부(200)는 출입홀부(130)의 삽입시 탄성변형되어 크기가 축소된다. 이후, 마개부(200)가 출입홀부(130)에 삽입되면, 탄성복원력에 의해 원상태로 복원되면서 출입홀부(130)에 끼움결합된다. The stopper 200 is made of an elastic material, and is fitted into the entry/exit hole 130 by an elastic restoring force. The stopper 200 is elastically deformed and reduced in size when the entry/exit hole 130 is inserted. Thereafter, when the stopper 200 is inserted into the entrance hole 130, it is fitted into the entrance hole 130 while being restored to its original state by an elastic restoring force.

마개부(200)는 접지선(21)과 결합되는 보강접지선(31)이 통과되는 통과홀부(210)를 구비한다. 통과홀부(210)는 마개부(200) 상에서 경사지게 형성된다. 통과홀부(210)는 마개부(200) 상에서 외측면(200a)에서 내측면(200b)으로 갈수록 상측으로 기울어지도록 경사지게 형성된다. 이로 인해, 통과홀부(210)로 빗물 등 이물질이 유입되는 것이 방지될 수 있다. The stopper 200 has a through hole 210 through which the ground wire 31 coupled with the ground wire 21 is passed. The through hole 210 is formed obliquely on the stopper 200 . The through hole 210 is formed to be inclined upward on the stopper 200 from the outer surface 200a to the inner surface 200b. Due to this, foreign substances such as rainwater may be prevented from being introduced into the passage hole 210 .

마개부(200)는 외측둘레에 출입홀부(130)에 결합되는 결합홈부(220)가 형성된다. 결합홈부(220)는 오목한 형상으로 직경(L1)이 출입홀부(130)의 직경(L2)과 동일하거나 출입홀부(130)의 직경보다 크다. 이로 인해, 마개부(200)는 탄성복원력에 의해 출입홀부(130)에 견고하게 결합될 수 있다. The stopper 200 is formed with a coupling groove 220 coupled to the entrance hole 130 on the outer circumference. The coupling groove 220 has a concave shape and has a diameter L1 equal to or larger than the diameter L2 of the entrance/exit hole 130 . Due to this, the stopper 200 can be firmly coupled to the entry/exit hole 130 by the elastic restoring force.

마개부(200)는 인입홀부(110) 및 인출홀부(120) 중 적어도 어느 하나에 결합된다. 즉, 마개부(200)를 이용하여 인입홀부(110) 및 인출홀부(120)를 폐쇄하여, 인입홀부(110) 및 인출홀부(120)로 이물질이 유입되는 것을 막을 수 있다. 또한, 마개부(200)의 통과홀부(210)를 통해 접지선(21)이 통과될 수 있다. The stopper 200 is coupled to at least one of the inlet hole 110 and the outlet hole 120 . That is, by using the stopper 200 to close the inlet hole 110 and the outlet hole 120, it is possible to prevent foreign matter from flowing into the inlet hole 110 and the outlet hole 120. Also, the ground wire 21 may pass through the passage hole 210 of the stopper 200 .
