본 고안은 방식전위측정용 리드선에 관한 것으로서, 특히 매설배관의 방식상태를 점검하기 위한 측정함 내의 리드선들이 산화되는 것을 방지하여 정확한 방식 전위값을 측정할 수 있고, 방식전위 측정을 손쉽게 하여 정비시간을 단축할 수 있는 방식전위측정용 리드선에 관한 것이다.The present invention relates to a lead wire for anticorrosive measurement, and in particular, to prevent the oxidation of the lead wires in the measuring box to check the anticorrosive state of the buried pipe, it is possible to measure an accurate anticorrosive potential value, and to maintain the anticorrosive potential for maintenance time. The present invention relates to a method for measuring potential dislocation wires.

액화천연가스 등의 수송을 위하여 지중에 매설된 배관은 통상 철계의 금속부재로 형성된다. 이러한 배관은 부식 등에 의한 열화를 방지하기 위하여 표면에 폴리에텔렌 등의 합성수지로 코팅을 하게 되며, 전기 화학적 반응의 결과인 부식을 억제할 수 있도록 전기방식(電氣防蝕)이 이용되고 있다.Pipes buried in the ground for the transport of liquefied natural gas or the like are usually formed of an iron-based metal member. In order to prevent deterioration due to corrosion, such a pipe is coated with synthetic resin such as polyetherene on the surface thereof, and an electric method is used to suppress corrosion resulting from an electrochemical reaction.

일반적으로 각종 금속배관의 부식을 방지하기 위한 전기방식설비는 토양으로부터 배관을 절연하기 위한 코팅과 함께 배관 보다 부식이 잘되는 희생양극을 도선으로 배관과 연결하여 배관을 방식하거나 외부에서 직류전원을 인가하여 배관을 방식하고 있다.In general, the electric anticorrosive equipment for preventing corrosion of various metal pipes is connected with pipes by sacrificial anodes that are more corrosive than pipes with coatings to insulate the pipes from the soil. Piping is done.

이와 같은 전기방식설비는 그 설치 및 주위한경, 예를 들어 지하철에 의한 누설전류, 다른 배관 등의 접지 또는 굴착공사에 의한 코팅손상 등의 변화의 영향으로 적정한 방식이 이루어지지 않을 수 있으므로 수시로 방식상태를 점검하여야 한다.Such electric anticorrosive equipment may not be properly operated due to the change of its installation and ambient environment, for example, leakage current caused by subway, ground damage of other pipes, or coating damage caused by excavation work. Should be checked.

도 1은 일반적인 매설배관의 방식전위측정용 전극의 설치상태를 도시한 것으로, 방식전위 측정함(1)은 차도, 인도 등의 노면에 매립되고 뚜껑(2)은 노출되어 이쓴 형태로 설치되어 있으며, 방식전위 측정함(1) 내부에는 배관에 연결된 배관리드선(3)과 접지를 위한 접지리드선(4)이 내장된다.Figure 1 shows the installation state of the anticorrosive potential measurement electrode of the general buried pipe, the anticorrosive potential measuring box (1) is embedded in the road surface, such as a roadway, sidewalks, and the lid (2) is exposed and installed in the form. In the anticorrosive potential measuring box 1, a pipe lead wire 3 connected to a pipe and a ground lead wire 4 for grounding are embedded.

도 2에 도시된 바와 같이 종래의 배관리드선(3) 또는 접지리드선(4)은 모두 구리 등과 같은 도전체로 이루어진 전극선(3a,4a)과 전극선(3a,4a)의 외부를 둘러 싸서 전극선(3a,4a)을 외부로부터 절연하기 위한 절연체(3b,4b)와, 최외각에 고무 등의 수지로 피복되어 리드선을 보호하는 보호피복체(3c,4c)로 구성된다.As shown in FIG. 2, the conventional pipe lead wire 3 or the ground lead wire 4 both surround the outside of the electrode wires 3a and 4a and the electrode wires 3a and 4a made of a conductor such as copper. Insulators 3b and 4b for insulating 4a) from the outside and protective coatings 3c and 4c which are covered with a resin such as rubber on the outermost side to protect the lead wire.

배관리드선(3)은 지중에 매설된 배관(6)으로부터 인출되어 있으며, 접지리드선(4)은 지중에 접지되어 있다. 미설명부호 5는 기준전극으로 통상적으로 마그네슘(Mg)을 사용한다. The pipe lead wire 3 is drawn out from the pipe 6 embedded in the ground, and the ground lead wire 4 is grounded in the ground. Reference numeral 5 generally uses magnesium (Mg) as a reference electrode.

이와 같은 방식전위 측정함(1)은 배관(6)의 경로를 따라서 일정 구간마다 설치하고, 이 측정함(1)으로부터 전위측정장치를 사용하여 일정한 주기로 배관(6)의 방식전위를 수작업으로 측정한 다음, 측정된 전위를 보고 배관(6)의 방식상태를 판별한다.Such an anticorrosive measuring box 1 is installed at regular intervals along the path of the pipe 6, and the anticorrosive potential of the pipe 6 is manually measured at regular intervals using a potential measuring device from the measuring box 1. Then, the measured potential is determined to determine the anticorrosive condition of the pipe 6.

종래의 경우 전위를 측정하기 위해 측정함(1) 내부에 있는 배관리드선(3)과 접지리드선(4)의 전극선(3a,4a)의 선단부에 위치한 측정단자부(A)에 감겨진 절연테이프를 벗겨낸 다음 전위측정장치로 측정하게 되는데 전극선(3a,4a)의 측정단자부(A)는 단지 절연테이프만 부착되어 있어 측정함(1) 내부의 환경에 따라 전극선(3a,4a)의 측정단자부(A)에 산화작용이 발생될 수 있으며, 이와 같은 산화작용에 의해 방식전위 측정시 정확한 전위값을 측정할 수 없으며, 방식전위 측정시 어느 리드선이 배관리드선인지 접지리드선인지 구별할 수 없으므로, 먼저 배관리드선과 접지리드선을 판별한 후 측정하여야 하므로 측정작업시간이 많이 소요되는 문제점을 가지고 있다.In the conventional case, the insulation tape wound on the measurement terminal portion A located at the tip of the electrode lead 3a and 4a of the pipe lead wire 3 and the ground lead wire 4 inside the measurement lead 1 to measure the electric potential is peeled off. The measuring terminal part A of the electrode wires 3a and 4a has only an insulating tape attached thereto, and the measurement terminal part A of the electrode wires 3a and 4a is measured according to the environment inside. The oxidation action may occur, and it is impossible to measure the exact potential value when measuring the anticorrosive potential by this oxidation, and it is not possible to distinguish which lead wire is the pipe lead wire or the ground lead wire when measuring the anticorrosive potential. Since it is necessary to measure after measuring the ground lead wire and has a problem that the measurement work takes a lot of time.

도 3 내지 도 5에 도시된 바와 같이 본 고안의 방식전위측정용 리드선은 일단이 개방되고, 타단이 밀봉되어 전극선(11)의 측정단자부(11a)를 포함하여 보호피복체(13)의 일단부를 둘러싸서 측정단자부(11a)를 외부로부터 절연시키는 접속단자(20)와, 접속단자(20) 외부와 보호피복체(13)의 일단부에 밀착되어 접속단자(20)가 보호피복체(13)에 고정되어 접속단자(20)가 보호피복체(13)로부터 이탈되는 것을 방지하는 이탈방지부(30)로 구성된다.3 to 5, one end of the anticorrosive potential measurement lead wire of the present invention is opened, and the other end thereof is sealed to include one end of the protective coating 13 including the measuring terminal portion 11a of the electrode line 11. The connecting terminal 20 which surrounds and insulates the measurement terminal part 11a from the outside, and the connection terminal 20 adheres to the one end of the outer side of the connecting terminal 20 and the protective coating body 13, and the protective terminal 13 is protected. It is fixed to the connection terminal 20 is composed of a departure prevention portion 30 to prevent the departure from the protective coating body (13).

이탈방지부(30)는 접속단자(20) 외부와 보호피복체(13)의 일단부를 둘러쌓은 후 이탈방지부(30)의 외부를 가열하여 이탈방지부(30)는 상기 보호피복체(13)의 외부와 접속단자(20)의 외부와 밀착되며, 이탈방지부(30)는 고무재의 탄력성을 갖는 다.The departure prevention part 30 surrounds the outside of the connection terminal 20 and one end of the protective coating 13, and then heats the outside of the separation prevention part 30 so that the departure prevention part 30 is the protective coating body 13.

상기의 구성에 따른 본 고안인 방식전위측정용 리드선의 동작은 다음과 같다.Operation of the anticorrosive potential measurement lead wire according to the above configuration is as follows.

도 3 내지 도 5에 도시된 바와 같이 선단에 방식전위를 측정하기 위한 측정단자부(11a)를 갖는 도전체로 이루어진 전극선(11)과, 전극선(11)의 외부를 둘러싸서 전극선(11)을 외부로부터 절연하기 위한 절연체(15)와, 절연체(15) 외부에 피복된 보호피복체(13)로 구성된 일반적인 방식전위측정용 리드선의 선단부에 위치한 측정단자부(11a)를 포함하여 보호피복체(13)의 일단부에 접속단자(20)를 삽입한다. 이와 같이 상단이 밀봉되고, 하단이 개방된 접속단자(20)에 의해 전극선(11)의 측정단자(11a)는 밀봉되므로 측정단자부(11a)는 주위 환경에 노출되지 않으므로 측정단자부(11a)는 산화작용이 발생되지 않기 때문에 방식전위 측정시 정확한 방식전위값을 측정할 수 있다.As shown in FIGS. 3 to 5, an electrode line 11 made of a conductor having a measuring terminal portion 11a for measuring anticorrosive potential at its tip, and the electrode line 11 is surrounded from the outside by surrounding the outside of the electrode line 11. Of the protective coating body 13, including a measuring terminal portion 11a located at the tip of a general anticorrosive potential measurement lead wire composed of an insulator 15 for insulation and a protective coating body 13 coated on the outside of the insulator 15; The connecting terminal 20 is inserted into one end. As such, the measuring terminal 11a of the electrode line 11 is sealed by the connection terminal 20 having the upper end sealed and the lower end opened, so that the measuring terminal part 11a is not exposed to the surrounding environment, so that the measuring terminal part 11a is oxidized. Since no action occurs, the correct anticorrosive value can be measured during anticorrosive measurement.

접속단자(20)를 측정단자부(11a)와 보호피복체(13)에 삽입한 후 양끝단이 개방된 탄력성을 갖는 고무재의 이탈방지부(30)를 접속단자(20)의 상부에서 보호피복체(13) 쪽으로 씌운 후 토치 등을 사용하여 이탈방지부(30)의 외주면을 가열시킨다. 가열된 이탈방지부(30)는 축소변형이 발생되면서 보호피복제(13)의 외부를 둘러싸고 있는 이탈방지부(30)는 보호피복제(13)와 밀착되고, 접속단자(20) 외부를 둘러싸고 있는 이탈방지부는 접속단자(20)를 밀착시켜 접속단자(20)는 보호피복제(13)와 밀착고정되어 접속단자(20)는 보호피복제(13)로부터 이탈되지 못한다.After the connection terminal 20 is inserted into the measuring terminal portion 11a and the protective coating body 13, the protective member is separated from the rubber material having the elasticity with both ends open. (13) and cover the outer peripheral surface of the separation prevention part 30 using a torch and the like. While the heated departure prevention part 30 is reduced in deformation, the departure prevention part 30 surrounding the outside of the protective coating 13 is in close contact with the protective coating 13 and surrounds the outside of the connection terminal 20. The detachment prevention part is in close contact with the connection terminal 20 so that the connection terminal 20 is fixed in close contact with the protective coating 13 so that the connection terminal 20 cannot be separated from the protective coating 13.

또한, 측정단자부(11a)가 근접한 위치의 보호피복체(13) 외주면에 리드선의 기능에 따른 리드선의 종류, 예를 들어 리드선이 배선리드선인지 접지리드선인지를 식별할 수 있는 식별표지부(40)를 부착한다. 식별표지부(40)를 외주면에 부착시키기 위해 양끝이 개방된 고무재의 식별표지부(40)를 보호피복체(13)에 외주면에 삽입하면 된다. 또한, 리드선의 종류를 식별하기 위하여 식별표지부(40)를 색상별로 구분하거나 식별표지부(40)의 표면에 문자 등을 기재하여 식별표식을 할 수 있다.In addition, on the outer circumferential surface of the protective coating 13 at the position where the measurement terminal portion 11a is adjacent, an identification mark portion 40 capable of identifying the type of lead wire according to the function of the lead wire, for example, whether the lead wire is a wire lead wire or a ground lead wire, is provided. Attach. In order to attach the identification mark portion 40 to the outer circumferential surface, the identification mark portion 40 of the rubber material having both ends opened may be inserted into the protective coating body 13 on the outer circumferential surface. In addition, in order to identify the type of the lead wire, the identification mark portion 40 may be classified by color, or an identification mark may be made by writing a character or the like on the surface of the identification mark portion 40.

상기와 같이 측정함 내부에 있는 일반적인 리드선의 측정단자(11a)를 밀봉시키고, 보호피복체(13)에 외주면에 삽입된 접속단자(20)와 이탈방지부(40)에 의해 측정단자(11a)는 주위환경에 노출되지 않으므로 산화작용이 발생되지 않으므로 방식전위 측정시 정확한 값을 측정할 수 있으며, 방식전위 측정시 노출된 접속단자(20)를 힘을 주어 잡아당기면 접속단자(20)와 이탈방지부(30)는 손쉽게 리드선에서 이탈되므로 방식전위를 손쉽게 측정할 수 있다.As described above, the measuring terminal 11a of the general lead wire inside the measuring box is sealed, and the measuring terminal 11a is inserted into the protective coating 13 by the connecting terminal 20 and the separation preventing part 40 inserted into the outer circumferential surface. Since the oxidation does not occur because it is not exposed to the surrounding environment, it is possible to measure the exact value when measuring the anticorrosive potential, and when the anticorrosive potential is applied by pulling the exposed connection terminal 20 to prevent the connection terminal 20 and departure Since the part 30 is easily separated from the lead, the anticorrosive potential can be easily measured.

또한, 식별표지부(40)에 의해 어떤 리드선이 배관리드선인지 접지리드선인지를 쉽게 식별할 수 있으므로 방식전위 측정시 빠른 시간에 방식전위를 측정할 수 있다. In addition, since the identification mark unit 40 can easily identify which lead wire is a pipe lead wire or a ground lead wire, it is possible to measure the anticorrosive potential at a fast time during the anticorrosive potential measurement.

본 고안의 방식전위측정용 리드선은 일단이 개방되고, 타단이 밀봉되어 전극선의 측정단자부를 포함하여 보호피복체의 일단부를 둘러싸서 측정단자부를 외부로 부터 절연시키는 접속단자와 접속단자 외부와 보호피복체의 일단부를 둘러싸서 접속단자가 보호피복체로부터 이탈되는 것을 방지하는 이탈방지부를 구비하여 측정단자부가 산화되는 것을 방지하여 정확한 방식전위값을 측정할 수 있고, 보호피복체의 일단부 외부를 둘러싸는 식별표지부를 구비하여 리드선을 손쉽게 구별할 수 있어 방식전위 측정을 손쉽게 하여 정비시간을 단축할 수 있다. The lead wire for the anticorrosive measurement of the present invention has an open end, a sealed end, and a connection terminal for insulating one end of the protective coating body including the measuring terminal portion of the electrode line, and insulating the measurement terminal portion from the outside, and the protective terminal outer and protective coating. It has an escape prevention part that surrounds one end of the sieve and prevents the connection terminal from being separated from the protective coating body. It prevents the measurement terminal part from oxidizing, so that an accurate anticorrosive value can be measured, and surrounds the outside of one end of the protective coating. Equipped with an identification mark, the lead wire can be easily distinguished, so it is possible to reduce the maintenance time by easily measuring the anticorrosive potential.
