廠家熱銷太陽能光伏BVR4接地線

接地方式 :光伏電站接地系統通常有兩大類：一是防雷接地，二是工作接地。不同類型的接地，要求也不盡相同。防雷接地的接地電阻值一般在4-30歐，而工作接地的接地電阻一般在0.5-10歐。光伏電站占地面積雖大但布局空間有限，為了滿足接地電阻的要求，往往采用全站共用接地系統的設計方案。 
雙色接地線 黃綠接地線就是直接連接地球的線，也可以稱為安全回路線，危險時它就把高壓直接轉嫁給地球，算是一根生命線。

安裝：將接地軟銅線分相上雙眼銅鼻子固定在接地棒上的接電夾（接電夾有固定式和活動式）相應位置上，將接地線合相上的單眼銅鼻子固定在接地夾或地針上，構成一套完整的接地線。
嚴禁使用其它金屬線代替接地線。

在實際工程中，要特別注意本工程地域特點，有的放矢。以青海省為例，即便相鄰的兩工程中接地系統敷設所遇到的問題卻不盡相同。有的站區土壤多含碎石，主要需解決土壤電阻率較高的問題；而相鄰站區則可能由于地下鹽堿水問題則需特別注意防腐。

After a deliberate survey of the situation, Tim made a sudden spring to the side of his enemy, caught him under his chest, and turned him upon his back. This side attack was unexpected 106 and a perfect success, and the reptile had an active and prolonged struggle to regain his natural ition. Tim watched the struggle with intense interest, seeming to be happy in knowing that he held the key to the situation. From that time on, his guest during the daylight hours had no peace. Whenever Tim had an opportunity, he turned him over, and, when not engaged in that diversion, he was chasing him around the enclosure. About one month of such an existence brought the Saurian very near to his end. From a most healthy and vigorous “’gater” at the time he was caught he had become weak, weary and lank; so forlorn was his lamentable condition that he excited the sympathy of some human friend, who, during the night, opened the gate to the pen. The following morning the persecuted reptile was nowhere to be found. From that moment 107 Tim became his former self, watched anxiously at the gate for the coming of friends, and pleaded pertinaciously for the intoxicating beverage.

在打接地樁時，要撥能借地體能快速疏通事故大電流，保證接地質量。

土壤電阻率是單位長度土壤電阻的平均值，單位是歐姆?米。土壤電阻率的大小主要取決于土壤中導電離子的濃度、土壤含水量和土質顆粒的大小，

電氣設備的接地部分（1）接地體：與大地緊密接觸并與大地形成電氣連接的一個或一組導體。（2）外露可導電部分：電氣設備能觸及的可導電部分。正常時不帶電，故障時可能帶電，通常為電氣設備的金屬外殼。（3）主接地端子板：一個建筑物或部分建筑物內各種接地（如工作接地、保護接地）的端子和等電位連接線的端子的組合。如成排排列，則稱為主接地端子排。（4）保護線（PE）：將上述外露可導電部分，主接地端子板、接地體以及電源接地點（或人工接地點）任何部分作電氣連接的導體。對于連接多個外露可導電部分的導體稱為保護干線。（5）接地線：將主接地端子板或將外露可導電部分直接接到接地體的保護線。對于連接多個接地端子板的接地線稱為接地干線。（6）等電位連接：指各外露可導電部分和裝置外導電部分的電位實質上相等的電氣連接 。
ge over the moat, and another of a later date towards the village with a gentle slope up to it which served as an entrance. Prevost's little Flemish cart went in by this way and entered into a big square courtyard, a real parade ground, which was formed by the two northern towers and the two walls on the east and west, the first precinct of the fortress.
根據中性線與保護線是否合并的情況，TN系統又分為TN-C、TN－S及TN－C－S系統。 TN－C系統：保護線與中性線合并為PEN線。 TN-S系統：保護線與中性線分開。 TN-C－S系統：在靠近電源側一段的保護線和中性線合并為PEN線，從某點以后分為保護線和中性線。
我國配電系統的接地方式已使用IEC規定，其分類仍然是以配電系統和電氣設備的接地組合來分，一般分為TN、TT、IT系統等。上述字母表示的含義：第一個字母表示電源接地點對地的關系。其中T表示直接接地；I表示不接地或通過阻抗接地。第二個字母表示電氣設備的外露可導電部分與地關系。其中T表示與電源接地點無連接的單獨直接接地；N表示直接與電源系統接地點或與該點引出的導體連接。
