활선 상태에서의 오일 채취 구조{OIL EXTRACTOR STRUCTURE IN THE LIVE TRANSMISSION LINE}OIL EXTRACTOR STRUCTURE IN THE LIVE TRANSMISSION LINE}

본 발명은 초고압 OF 케이블의 활선 오일을 채취할 수 있도록 하는 구조에관한 것으로, 좀 더 자세하게는 고전압 케이블을 연결하는 접속함의 내부에 충진된 오일을 채취하도록 하는 본체 내부에 오일의 저장을 위한 저장실이 구비됨으로서, 채취되는 오일에 불순물이 유입되는 것을 방지하도록 함을 특징으로 한다.The present invention relates to a structure for collecting the live oil of the ultra-high voltage OF cable, and more specifically, the storage compartment for storing the oil in the body to collect the oil filled in the interior of the junction box connecting the high-voltage cable By being provided, it is characterized in that to prevent impurities from flowing into the oil to be collected.

일반적으로 초고압 케이블은 길이가 한정되어 있기 때문에, 초고압 케이블을 설치하기 위해서는 일정 길이마다 케이블과 케이블을 연결하는 접속함이 설치된다.In general, since the ultra-high voltage cable is limited in length, in order to install the ultra-high voltage cable, a junction box for connecting the cable and the cable every predetermined length is installed.

그리고, 상기 접속함에는 절연유(오일)가 내장되어 고압의 전류가 외부로 전도되는 것을 방지하게 되는데, 이러한 절연유를 채취하여 관찰하면 케이블의 노후상태를 알게 되고 교체시기를 적절하게 선택할 수 있다.In addition, the junction box is embedded with an insulating oil (oil) to prevent a high-voltage current from conducting to the outside. By collecting and observing the insulating oil, the aged state of the cable can be known and the replacement time can be appropriately selected.

그러나, 케이블에는 고전압이 흐르기 때문에 활선 상태에서 절연유를 채취하기가 쉽지 않아 정전 상태에서 절연유를 채취하여 왔다.However, since high voltage flows through the cable, it is not easy to collect the insulating oil in the live state, and thus, the insulating oil has been collected in the blackout state.

한편, 일본 특개평 7-264740은 활선 상태에서 절연유를 채취하는 장치를 제안한 것으로서, 도 1은 이에 대한 개략적인 오일채취구조를 나타내는 단면이다.On the other hand, Japanese Patent Laid-Open No. 7-264740 proposes a device for collecting insulating oil in a live state, Figure 1 is a cross-sectional view showing a schematic oil extraction structure for this.

도시된 바와 같이, 종래에는 밀봉 접속 용기(3)의 커넥터 장착구(3b)에 무 정전 채유장치(A)를 설치하고, 절연 회동체(6)의 하면에 형성된 커넥터 설치부(7)에 커넥터(4)를 설치한다.As shown, conventionally, the electrostatic free device A is installed in the connector mounting opening 3b of the sealed connection container 3, and the connector is installed in the connector mounting portion 7 formed on the lower surface of the insulated pivoting body 6. (4) is installed.

이 경우 금속제 커넥터(4)는 절연통 본체(5) 안으로 들어가 외부에 드러나지 않고, 또한 커넥터(4)의 조작도 절연 회동체(6)를 통한 조작이기 때문에, 작업 부문은 절연통 본체(5)나 절연 회동체(6) 안에 절연된다.In this case, since the metal connector 4 enters into the insulated cylinder body 5 and is not exposed to the outside, and the operation of the connector 4 is also operated through the insulated pivot body 6, the work section is the insulated cylinder body 5. B) insulated in the rotating body (6).

이러한 상태에서 채유기 장착부(9)에 기름통을 장착하고, 절연 회동체(6)를 회전시키면 절연 회동체(6)와 함께 커넥터(4)도 회전하여 오일 유출구(10)를 열면,오일이 오일 유출구(10)로부터 유출된다.In this state, when the oil sump is mounted on the oil sump mounting unit 9 and the insulating pivoting body 6 is rotated, the connector 4 also rotates together with the insulating pivoting body 6 to open the oil outlet 10. It flows out of the oil outlet 10.

상기 오일 유출구(10)를 통해 유출된 오일은 오일 유출로(11)를 통과하여 오일 유출구(10)로부터 채유기 장착부(9)에 이르고, 준비한 기름통에 저장되게 된다.The oil flowing out through the oil outlet 10 passes through the oil outlet 11 and reaches the oil sump mounting unit 9 from the oil outlet 10 and is stored in the prepared oil sump.

그러나, 상기한 구성은 활선 상태의 오일을 채취하는 채유 장치내에 오일을 저장할 수 있는 저장실이 없기 때문에, 오일의 채유시 오일이 이동하면서 기름통에 저장되는 동안 수분이나 불순물에 노출될 가능성이 높아 채유 후 오일의 분석시 정확한 오일의 특성을 가늠하기가 어렵다는 문제점이 있었다.However, since the above configuration does not have a storage compartment for storing oil in the oil collection device for collecting oil in a live state, oil is more likely to be exposed to moisture or impurities while oil is being stored and stored in the oil container when oil is collected. There was a problem that it is difficult to determine the exact characteristics of the oil when analyzing the oil.

이에 본 발명은 상기와 같은 문제점들을 해소하기 위해 안출된 것으로써, 본 발명은 접속함의 커넥터와 결합하는 본체 내부에 오일의 저장을 위한 저장실이 형성되어, 접속함에 충진된 오일이 저장실에 저장될 때, 오일에 불순물이 유입되지 않도록 하는 것을 목적으로 한다.Accordingly, the present invention has been made to solve the above problems, the present invention is a storage compartment for the storage of oil is formed in the body coupled with the connector of the junction box, when the oil filled in the junction is stored in the storage compartment The aim is to prevent impurities from entering the oil.

상기와 같은 구조로 이루어진 본 발명의 작용 및 효과는 다음과 같다.The action and effect of the present invention made of the above structure is as follows.

접속함에 충진된 오일을 채취하기 위해 먼저, 본체(23)를 커넥터(21)에 밀착시키고, 개폐수단(31)의 오프너(32)를 커넥터(21)의 마개(32)에 안착시킨다.In order to collect the oil filled in the junction box, first, the main body 23 is brought into close contact with the connector 21, and the opener 32 of the opening and closing means 31 is seated on the plug 32 of the connector 21.

상기한 상태에서, 개폐수단(31)의 핸들(34)을 회전시키면 축봉(33)을 동력 매개로 하는 오프너(32)는 상기 핸들(34)의 회전방향에 따라 회전하면서 마개(22)를 개방하거나 폐쇄시킨다.In the above state, when the handle 34 of the opening and closing means 31 is rotated, the opener 32 which drives the shaft bar 33 as a power medium opens the stopper 22 while rotating in the rotational direction of the handle 34. Or close it.

만일, 상기 마개(22)가 개방되면 접속함에 충진된 오일은 압력차에 의해 분출되고, 이렇게 분출된 오일은 본체(23)의 저장실(24)에 저장되게 된다.If the stopper 22 is opened, the oil filled in the junction is ejected by the pressure difference, and the oil thus ejected is stored in the storage chamber 24 of the main body 23.

이렇게 저장실(24)에 오일을 저장시키고, 본체(23)를 커넥터(21)에서 분리시킨 다음, 저장실(24)의 개방된 부분을 커버하여 본체(23)를 오일측정장소로 옮긴다.In this way, the oil is stored in the storage chamber 24, the main body 23 is separated from the connector 21, and then the main body 23 is moved to the oil measuring place by covering the open portion of the storage chamber 24.

그리고, 오일측정장소에서는 본체(23)에 저장된 오일을 채취하여 측정함으로서, 케이블의 노후 여부를 판별하게 된다.At the oil measurement site, the oil stored in the main body 23 is collected and measured to determine whether the cable is old.

한편, 오일에 불순물이 첨가되는 것을 방지하기 위해, 최초 본체(23)의 저장실(24)에 오일을 저장하기 전에 배출관(41)의 밸브(42)를 개방하여 일정량의 오일을 배출시킨다.On the other hand, in order to prevent impurities from being added to the oil, the valve 42 of the discharge pipe 41 is opened before the oil is stored in the storage chamber 24 of the first main body 23 to discharge a certain amount of oil.

그리하면, 혹시라도 저장실(24) 내부에 내재된 불순물이 오일과 함께 배출됨으로서, 접속함에 충진된 원액 그대로를 저장하게 된다.Then, even if the impurity inherent in the storage chamber 24 is discharged together with the oil, the stock solution filled in the junction box is stored as it is.

상기한 바와 같이 본 발명에 따른 활선 상태에서의 오일 채취 구조는 본체 내부에 오일을 저장하기 위한 저장실이 형성되어 오일에 불순물이 유입되는 것을 방지함으로서, 보다 정확한 오일의 측정이 가능하다는 이점이 있다.As described above, the oil collecting structure in the live state according to the present invention has an advantage in that a storage chamber for storing oil is formed inside the main body to prevent impurities from flowing into the oil, thereby measuring oil more accurately.
