    • 본 발명은 지중에 매설된 강재 가스배관의 방식전위를 측정하기 위하여 가스배관과 전선으로 연결된 접속단자가 설치되는 방식전위 측정함에 관한 것이다.
      특히, 시가지 외의 도로, 산지, 농지 또는 철도부지의 경우 지면에 입상(pole type)으로 설치되는 방식전위 측정함을 설치하고 있으며, 상기 측정함 내부에 전도체와 부전도체로 이루어진 단자고정판을 형성하여 전자공여체(D1,D2) 전위측정을 위한 제1,2 전선(L1,L2)과 배관(P) 전위측정을 위한 제3,4 전선(L3,L4)을 개별적으로 측정단자에 의해 고정되어 추가적인 해제작업 없어 방식전위 측정시간을 단축할 수 있으며, 상기 측정함의 몸체 하단에 전선(L1,L2,L3,L4) 인출홈을 형성하여 상기 몸체의 하단을 지중에 매설시 상기 몸체의 하단과 측정함 내부로 인출되는 상기 전선이 서로 맞닿아 전선의 외주연에 설치된 보호피복체가 손상되어 전선의 피복손상부로부터 방식전류의 누설 등으로 인한 적정 방식전위를 유지하기 위한 방식전류의 증가로 인한 희생양극, 즉 전자공여체(D1,D2, donor)의 교체주기단축을 방지함으로써 방식전위설비의 유지관리비용을 절감할 수 있다.
    • 本发明涉及一种保护电位测试箱,其中安装了通过电线连接到气体管道的连接端子,以测量地下钢管道的保护电位。 保护电位测试箱安装在地面上,特别适用于城市以外的道路,山脉,农田或铁路。 保护电位测试箱可以通过在测试箱内部形成由导电体和不导电体构成的端子固定板,并固定用于测量的第一和第二电线(L1,L2)来缩短保护电位测量时间 电子供体(D1,D2)和第三和第四电线(L3,L4)的保护电位,用于分别测量管道(P)的保护电位到测量端子,以消除拆卸工作的需要。 当身体的底部埋在地下时,安装在电线外圆周上的保护涂层体可能会因测试箱体的底部和被抽出到电线内部的电线之间的接触而损坏 因此,保护​​电流增加,以保持适当的保护电位,防止由于电线上损坏的涂层部分导致的保护电流泄漏。 为了解决这个问题,为了防止作为电动阳极的电子供体(D1,D2)的更换周期,在测试箱体的底部形成电线(L1,L2,L3,L4)取出槽, 从而缩短了保护潜力设施的维护成本。
