厂家热销太阳能光伏BVR4接地线

接地方式 :光伏电站接地系统通常有两大类：一是防雷接地，二是工作接地。不同类型的接地，要求也不尽相同。防雷接地的接地电阻值一般在4-30欧，而工作接地的接地电阻一般在0.5-10欧。光伏电站占地面积虽大但布局空间有限，为了满足接地电阻的要求，往往采用全站共用接地系统的设计方案。 
双色接地线 黄绿接地线就是直接连接地球的线，也可以称为安全回路线，危险时它就把高压直接转嫁给地球，算是一根生命线。

安装：将接地软铜线分相上双眼铜鼻子固定在接地棒上的接电夹（接电夹有固定式和活动式）相应位置上，将接地线合相上的单眼铜鼻子固定在接地夹或地针上，构成一套完整的接地线。
严禁使用其它金属线代替接地线。

在实际工程中，要特别注意本工程地域特点，有的放矢。以青海省为例，即便相邻的两工程中接地系统敷设所遇到的问题却不尽相同。有的站区土壤多含碎石，主要需解决土壤电阻率较高的问题；而相邻站区则可能由于地下盐碱水问题则需特别注意防腐。

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.

土壤电阻率是单位长度土壤电阻的平均值，单位是欧姆?米。土壤电阻率的大小主要取决于土壤中导电离子的浓度、土壤含水量和土质颗粒的大小，

电气设备的接地部分（1）接地体：与大地紧密接触并与大地形成电气连接的一个或一组导体。（2）外露可导电部分：电气设备能触及的可导电部分。正常时不带电，故障时可能带电，通常为电气设备的金属外壳。（3）主接地端子板：一个建筑物或部分建筑物内各种接地（如工作接地、保护接地）的端子和等电位连接线的端子的组合。如成排排列，则称为主接地端子排。（4）保护线（PE）：将上述外露可导电部分，主接地端子板、接地体以及电源接地点（或人工接地点）任何部分作电气连接的导体。对于连接多个外露可导电部分的导体称为保护干线。（5）接地线：将主接地端子板或将外露可导电部分直接接到接地体的保护线。对于连接多个接地端子板的接地线称为接地干线。（6）等电位连接：指各外露可导电部分和装置外导电部分的电位实质上相等的电气连接 。
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.
根据中性线与保护线是否合并的情况，TN系统又分为TN-C、TN－S及TN－C－S系统。 TN－C系统：保护线与中性线合并为PEN线。 TN-S系统：保护线与中性线分开。 TN-C－S系统：在靠近电源侧一段的保护线和中性线合并为PEN线，从某点以后分为保护线和中性线。
我国配电系统的接地方式已使用IEC规定，其分类仍然是以配电系统和电气设备的接地组合来分，一般分为TN、TT、IT系统等。上述字母表示的含义：第一个字母表示电源接地点对地的关系。其中T表示直接接地；I表示不接地或通过阻抗接地。第二个字母表示电气设备的外露可导电部分与地关系。其中T表示与电源接地点无连接的单独直接接地；N表示直接与电源系统接地点或与该点引出的导体连接。
