Zusammenfassung: | The present invention relates to an anti-overlap system for a reverse surge traveling wave, which reduces the reverse surge traveling wave generated from a low potential value ground line by analyzing a potential difference between ground lines discharging a surge current to the ground. According to the present invention, the anti-reflection/overlapping prevention system comprises: a ground line potential measurement device (300) measuring a potential value of a ground line; and a reverse surge traveling wave prevention device (100) having protective elements disposed and connected in parallel between adjacent ground lines and having different impedance values and checking the potential difference between the ground lines measured by the ground line potential measurement device (300) to connect the protective elements selectively so that the reverse surge generated from the ground line having a low potential value is lowered to a standard or less.
본 발명은 서지전류를 지면으로 방출시키는 접지라인 사이의 전위차를 분석하여 전위값이 낮은 접지라인에서 발생되는 역서지 진행파를 최소화되도록 감소시키는 역서지 진행파의 반사중첩 방지시스템에 관한 것이다. 본 발명에 따른 역서지 진행파의 반사중첩 방지시스템은, 접지라인의 전위값을 측정하는 접지라인 전위측정장치(300)와; 인접하는 접지라인 사이에 연결되어 있으면서 서로 다른 임피던스값을 갖는 보호소자가 병렬방식으로 위치하며, 접지라인 전위측정장치(300)에서 측정된 접지라인 사이의 전위차를 확인하여 낮은 전위값을 갖는 접지라인에서 발생된 역서지가 기준 이하가 되도록 선택적으로 보호소자를 연결하는 역서지 진행파의 방지장치(100)를 포함하는 것을 특징으로 한다. |
