일반적으로, 변전소에서 여러 단계의 변압과정을 거친 전력을 가정 또는 건물 등의 수용가로 공급하기 위해서는 지상에 일정 간격으로 설치되는 전주 등에 의해 지지되는 가공지선을 이용하게 된다. 이러한 가공지선은 이상전류(뇌, 지락, 서지 등)로부터 배전설비를 보호함과 아울러 누전으로 인한 각종 전기재해를 방지하기 위하여 접지장치와 연결된다. 접지장치는 전주에 내장된 가공지선과 연결되는 접지선과, 접지선과 전기적으로 연결되고, 대지에 매설되는 접지동봉을 포함한다. 그러나, 전주에 접지선이 내장되어 접지선의 접지 측정이 어려울 뿐만 아니라, 접지선을 보강할 경우 굴착이 필요하므로, 보강작업이 번거러운 문제점이 있다. 따라서, 이를 개선할 필요성이 요청된다.Generally, in order to supply power that has undergone several stages of transformation at a substation to consumers such as homes or buildings, overhead branch lines supported by electric poles installed on the ground at regular intervals are used. These overhead branch lines are connected to a grounding device to protect distribution facilities from abnormal currents (lightning, ground faults, surges, etc.) and to prevent various electrical disasters due to short circuits. The grounding device includes a grounding wire connected to an overhead ground wire built into an electric pole, and a grounding rod that is electrically connected to the grounding wire and buried in the ground. However, not only is it difficult to measure the grounding of the grounding wire because the grounding wire is built into the electric pole, but there is a problem in that reinforcing the grounding wire requires excavation, making reinforcement work cumbersome. Therefore, there is a need to improve this.

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 Figures 1 to 8, the electric pole device 1 with an embedded ground wire according to an embodiment of the present invention includes an electric pole 100 and a stopper 200. The electric pole 100 has a cylindrical shape and is installed on the ground 40 in the height direction. The electric pole 100 has a ground wire 21 connected to the processed ground wire 10 located inside. Specifically, the ground portion 20 includes a ground wire 21 and a ground rod 22. The ground wire 21 is inserted into the inlet hole 110 of the electric pole 100, passes through the space 140 of the electric pole 100, and is drawn out into the outlet hole 120 of the electric pole 100. The grounding rod 22 is connected to the grounding wire 21 and is buried in the ground 40 together with the grounding 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 reinforced grounding unit 30 includes a reinforced grounding wire 31 and a reinforced grounding rod 32. The reinforced ground wire 31 is combined with the ground wire 21 to reinforce the ground wire 21. The reinforced grounding rod (32) is connected to the reinforced grounding wire (31) and is buried in the ground (40) together with the reinforced grounding wire (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 includes an inlet hole 110, an outlet hole 120, and an exit hole 130. A ground wire 21 connected to the processed ground wire 10 is inserted into the lead-in hole 110. The ground wire 21 inserted into the lead-in hole 110 passes through the space 140 of the electric pole 100 and is drawn out into 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 portion 120 is disposed to be spaced apart from the lead-in hole portion 110, and the ground wire 21 is drawn out. The draw-out hole portion 120 is buried in the ground 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 part 130 is disposed between the inlet hole part 110 and the outlet hole part 120, and the ground wire 21 can enter and exit. The access hole portion 130 is located at a position spaced apart from the ground 40 at a set height. At this time, the setting height is preferably 0.5m. Because of this, work can be easily carried out on the ground. If the set height is less than or more than 0.5 m, there is a problem in that it is difficult to pull out 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 exits the access hole 130. In this way, the ground margin line 21a of the ground line 21 is drawn out through the access hole 130. At this time, the ground clearance line 21a has a set length, and a measuring device 50 can be installed or a reinforcing ground line 23 can be combined. At this time, the set length is preferably 0.3m. Because of this, it can be easy for an operator to install the measuring instrument 50 on the ground clearance line 21a to measure the ground resistance value of the ground wire 21 or to couple the reinforced ground wire 23 to the ground wire 21. At this time, the measuring device 50 measures the grounding resistance value of the grounding wire 21 using the hook-on method. Therefore, compared to the conventional technology of measuring the ground resistance value of the ground wire 21 by riding on an aerial work vehicle, the ground resistance value of the ground wire 21 can be measured on the ground, allowing work to 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 more than 0.3 m, the worker installs a measuring instrument (50) on the ground clearance line (21a) to measure the ground resistance value of the ground wire (21) or attaches a reinforced ground wire (23) to the ground wire (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 portion 200 is coupled to the access hole portion 130 and closes the access hole portion 130. The stopper portion 200 is coupled to the access hole portion 130 and closes the access hole portion 130 to prevent the access hole portion 130 from being exposed to the outside. Because of this, it is possible to prevent foreign substances from entering from the access 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 portion 200 is made of an elastic material and is fitted into the access hole portion 130 by elastic restoring force. When the stopper portion 200 is inserted into the access hole portion 130, it is elastically deformed and its size is reduced. Thereafter, when the stopper part 200 is inserted into the access hole part 130, it is restored to its original state by elastic restoring force and is fitted into the access hole part 130.

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 portion 200 has a through hole portion 210 through which the reinforcing ground wire 31 coupled to the ground wire 21 passes. The passage hole portion 210 is formed to be inclined on the stopper portion 200. The passage hole portion 210 is formed to be inclined upward on the stopper portion 200 from the outer surface 200a to the inner surface 200b. Because of this, foreign substances such as rainwater can be prevented from flowing into the passage hole portion 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 portion 200 has a coupling groove portion 220 coupled to the access hole portion 130 formed on its outer circumference. The coupling groove portion 220 has a concave shape and a diameter (L1) is the same as the diameter (L2) of the access hole portion 130 or is larger than the diameter of the access hole portion 130. Because of this, the stopper portion 200 can be firmly coupled to the access hole portion 130 by 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 portion 200 is coupled to at least one of the lead-in hole portion 110 and the pull-out hole portion 120.
