BVR4平方太阳能光伏接地线

在光伏电站的建设施工过程中，接地工程多为隐蔽工程和边角工程，经常被施工和监理人员所忽视。而有些接地系统一旦发生故障，在广阔的厂区检测故障点并修复往往要耗费大量人力和时间。因此，在建设过程中，各参建方应仔细审查、理解设计图纸，各专业协同合作，对于设计图纸中衔接不清或施工中存在的不确定应及时反映沟通，勿要放任敷衍，导致返工乃至威胁设备和人身安全。

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。
核实接地棒的电压等级与操作设备的电压等级是否一致。

一般在光伏电站中，接地引下线和接地体的电阻很小，多可忽略。系统的接地电阻主要为接地体到大地无限远处的电阻，即主要由接地体周围的土壤电阻率决定。 土壤电阻率 
Elizabeth’s profound diplomacy and quick intelligence were shown even thus early at this critical juncture. Sir Robert Tyrwhitt and his wife were sent by the Protector to worm out of her all she knew of the plot. Threats, cajolery, forged letters and invented confessions, were all tried upon her in vain. She would tell nothing of importance. “She hath,” says Tyrwhitt, “a very good wit and nothing is gotten of her but by great policy.” She bitterly resented the imprisonment of her governess, Mrs. Ashley, and the substitution of Lady Tyrwhitt; and said that she had not so behed that they need put more mistresses upon her; wept all night and sulked all day, but withal was too much for Tyrwhitt, who owed that “if he had to say his fantasy he thinks it more meet she should he two governesses than one.”

按不同电压等级选用对应规格的接地线。

挂接地线前必须先验电，未验电挂接地线是基层中较普遍的习惯性违章行为，在悬挂时接地线道体不能和身体接触。

the handsome, showy Seymour; but how far their relations went will most likely never now be known. She indignantly wrote to the Protector complaining of the slanders that were current about her, to the effect that she was with child by the Lord Admiral and demanded to be allowed to come to Court and “show herself as she was”; but virtuous indignation, real and assumed, was always one of her fourite weapons. Tyrwhitt said he believed a secret compact had been entered into between her and Ashley and Parry never to confess during their lives. “They all sing one song and she hath set the note for them.”
工作接地方式主要有以下三种类型：（1）中性点非直接接地方式（I-T）。用电设备中性点不接入大地，（2）单个保护接地方式（T-T）。电源变压器的中性点直接接地，用电设备外壳可导电部分直接接入大地（3）中性点直接接地方式（T-N）。在这种方式中，电力系统变压器中性点直接接地，用电设备外壳可导电部分通过接地引下线和接地系统作良好的金属性连接，。
