關於雷電
1.閃電的常識
1.閃電的平均電流:30,000A (目前記錄的最大值:300,000A)
2.閃電中心的空氣溫度: 攝氏 3000度
90%以上的閃電是雲層對雲層放電過程
3.雲層對地面的閃電次數:每秒種100次(全球範圍)
4.閃電的強度可達 1000000000 伏
5.一個中等強度雷暴的功率有 10000000 瓦(相當於一個小型核電站的輸出功率)
6.每年因雷擊造成的直接損失超過1000000000 美元(全球不含中國的統計)

♦主要特性
1,攝像機電源線和視頻信號線綜合保護
2,放電容量大,低電壓保護等級
3,快速響應,多級保護,對傳輸信號干擾小
安裝說明
1.突波保護器串聯在受保護的設備上。
2.輸出終端應連接到受保護的設備。
注意:“IN”端子電源必須安裝備用保險絲;
3.接地線應連接到接地系統,理想情況下使用2.5mm²電纜,電纜應盡可能短
4.開機時,綠燈亮起。
定期檢查運行狀態,特別是雷擊後 , 如果通信中斷,電工應檢查/更換 相機防雷器 。
