본 고안은 지중매설 배관의 부식 방지 방지 조치의 일환으로 설치되는 매몰절연 죠인트에 관한 것으로, 특히 절연부의 절연유지의 검사 및 관로의 절연과 본딩의 운용을 비굴착으로 실시하여 주기 위하여 단자가 인출된 단자형 매몰절연 죠인트에 관한 것이다.The present invention relates to a buried insulated joint installed as part of the anti-corrosion protection measures for underground buried pipes. It relates to a terminal investment insulated joint.
지중에 매설된 코팅배관에 있어서 기존 매설배관의 부식방지 조치가 된 방식전위와 새로 신설되는 배관의 방식전위는 서로 다를 수 있다. 또한 부식방지 장치를 설치한 배관과 부식방지 조치가 되지 않는 배관의 전위는 다르게 된다. 이렇게 서로 다른 방식전위를 가지고 있는 배관에 전기적 격리장치가 없이 연결되면 전위가 높은 쪽에서는 방식효과가 증가되고 전위가 낮은쪽에서는 방식효과가 떨어지는 현상이 발생된다. 따라서 이러한 곳에서 전기적으로 격리시킬 수 있게 매몰절연 죠인트를 절연장치로 사용하고 있다.In the underground coating pipe, the anticorrosive potential of the existing buried pipe may be different from that of the newly installed pipe. Also, the potentials of pipes with corrosion protection devices and pipes without corrosion protection measures are different. If there is no electrical isolator connected to the pipes having different anticorrosive potentials, the anticorrosive effect is increased at the high potential and the anticorrosive effect is decreased at the low potential. Therefore, buried insulated joints are used as insulation devices to electrically isolate these places.
이러한 매몰절연 죠인트는 주위의 부식환경 변화와 절연부 양단에 현저한 전위차 또는 고전압의 유입등으로 절연부가 파괴되거나 환경여건에 따라 절연부의 본딩이 절연부의 절연을 유지하는지 검사할 필요가 있다. 그러나 현재의 매몰절연 죠인트를 검사하기 위해서는 매설된 절연죠인트 양단의 코팅을 벗겨내고 카드 웰딩에 의해 용접을 실시하여 동선과 배관의 금속부분을 접합시켜야 하나 굴착작업이 번거롭고 동선과 배관의 금속부분의 접합이 양호하게 되지 않으며 카드 웰딩 접합시의 불꽃으로 작업에 위험성이 있다.Such investment insulation joints need to be examined to determine whether the insulation breaks down due to changes in the surrounding environment and significant potential difference or inflow of high voltage across the insulation, or the bonding of the insulation maintains insulation according to environmental conditions. However, to inspect the current investment insulation joints, the coatings on both ends of the embedded insulation joints should be peeled off and welded by card welding to join the copper parts and the metal parts of the pipe. This is not satisfactory and there is a risk of operation due to the flame at the time of card welding bonding.
본 고안의 목적은 상기와 같은 단점을 해결하기 위하여 절연죠인트 단자를 설치하고 케이블의 단자 접속부를 단자와 스크류 접속하여 테스트 박스에서 절연죠인트의 본딩 및 절연측정을 종합적으로 실시할 수 있는 단자형 매몰절연 죠인트를 제공하고자 하는 것이다.The purpose of the present invention is to install the insulation joint terminal and screw connection of the terminal connection part of the cable to the terminal to solve the above disadvantages, the terminal type investment insulation to comprehensively perform the bonding and insulation measurement of the insulation joint in the test box We want to provide a joint.
본 고안을 첨부된 도면을 참조하여 하기에 설명한다.The present invention will be described below with reference to the accompanying drawings.
제1도에는 본 고안의 단자형 매몰절연 죠인트의 단면도가 도시되는데, 2개의 파이프(1) 및 (2)는 절연부(3)에 의해서 연결되고 있고 절연부(3)는 절연가이드(4) 및 (5)에 의해서 파이프(1) 및 (2)를 절연시키며 절연가이드(4) 및 (5) 사이에는 기밀을 위하여 O링(7)이 설치된다. 파이프(1) 및 (2)의 연결부는 파이프 가이드(6)로 지지되고 FRP로 코팅된다.1 is a cross-sectional view of the terminal type investment-insulating joint of the present invention, in which two pipes 1 and 2 are connected by an insulating part 3 and the insulating part 3 is an insulating guide 4. And (5) to insulate the pipes (1) and (2), and between the insulation guides (4) and (5), an O-ring (7) is provided for airtightness. The connections of pipes 1 and 2 are supported by pipe guides 6 and coated with FRP.
본 고안의 파이프(1) 및 (2)에는 볼트형 단자(8)가 용접되고 그위에 FRP코팅(9)이 배치된다.In the pipes 1 and 2 of the present invention, the bolt-shaped terminal 8 is welded and the FRP coating 9 is disposed thereon.
제2도는 본 고안의 단자 접속부가 확대되어 도시되는데, 볼트형 단자(8)에는 단자용 너트(10)가 스크류 접속되고, 단자용 너트(10)의 내부에서 리드선 방향으로 단자고리(12)를 끼워 넣고, 외부로 돌출되어 나온 단자고리(12)의 단부와 리드선(11)은 압착슬리브(13)에 의해서 고정된다. 리드선(11)의 반대쪽 단부에는 제1도에 도시된 바와 같이 압축단자(14)가 연결되어 있다.2 is an enlarged view of the terminal connecting portion of the present invention, the terminal nut 10 is screw-connected to the bolt-shaped terminal 8, the terminal ring 12 in the direction of the lead wire inside the terminal nut 10 The end of the terminal ring 12 and the lead wire 11 which are inserted and protrude outwardly are fixed by the crimping sleeve 13. The compression terminal 14 is connected to the opposite end of the lead wire 11 as shown in FIG.
제3도에는 본 고안의 단자형 매몰절연 죠인트가 테스트 박스에 연결된 상태가 도시되는데, 파이프(1) 및 (2)와 절연부(3)는 지하에 매설되고 리드선(11)의 압축단자(14)는 PVC 파이프(16)를 통하여 지면에 설치된 테스트 박스(15)에 위치된다.3 shows a state in which the terminal type investment insulated joint of the present invention is connected to a test box. The pipes 1 and 2 and the insulation 3 are buried underground and the compression terminal 14 of the lead wire 11 is connected. ) Is placed in the test box 15 installed on the ground through the PVC pipe 16.
상기와 같이 구성된 본 고안의 단자형 매몰절연 죠인트는 파이프(1) 및 (2)에 용접된 볼트형 단자(8)가 리드선(11)에 의해서 테스트 박스(15)의 압축단자(14)로 연결되어 있으므로 절연부를 검사하려면 압축단자(14)를 테스트하면 되므로 굴착하지 않고도 지상에서 절연죠인트 양단의 전위측정 또는 절연측정으로 절연부의 절연성 검사가 용이하게 행하여 질 수 있다.In the terminal-type investment insulated joint of the present invention configured as described above, the bolt-type terminal 8 welded to the pipes 1 and 2 is connected to the compression terminal 14 of the test box 15 by the lead wire 11. Since the compression terminal 14 is tested to inspect the insulation, the insulation inspection of the insulation can be easily performed by measuring the potential or insulation of both ends of the insulation joint without drilling.
또한, 배관의 상호 절연된 부근에서 직류전철의 레일 누설전류가 발생하거나 고주파 기기를 사용하는 장소에서 접지에 따라 누설된 전류가 있은 경우에 누설된 전류는 강한 부식을 나타내므로 배류장치를 이용하여 누설된 전류를 레일로 되돌려 보내게 되는데, 본 고안의 단자형 매몰절연 죠인트는 압축단자(14)를 이용하여 지상에서 매설 절연부를 본딩할 수 있어 주위환경 변화에 따른 절연 및 본딩 운용이 쉽게 되는 효과도 제공된다.In addition, when the leakage current of DC rail is generated in the vicinity of mutually insulated pipes or there is a leakage current according to the ground in the place where high frequency equipment is used, the leaked current shows strong corrosion. The current is sent back to the rail, the terminal type investment insulated joint of the present invention can use the compression terminal 14 to bond the buried insulation on the ground, so that the insulation and bonding operation according to the change of the surrounding environment is also easy. Is provided.
