BVR4平方太陽能光伏接地線

在光伏電站的建設(shè)施工過程中，接地工程多為隱蔽工程和邊角工程，經(jīng)常被施工和監(jiān)理人員所忽視。而有些接地系統(tǒng)一旦發(fā)生故障，在廣闊的廠區(qū)檢測故障點并修復(fù)往往要耗費大量人力和時間。因此，在建設(shè)過程中，各參建方應(yīng)仔細(xì)審查、理解設(shè)計圖紙，各專業(yè)協(xié)同合作，對于設(shè)計圖紙中銜接不清或施工中存在的不確定應(yīng)及時反映溝通，勿要放任敷衍，導(dǎo)致返工乃至威脅設(shè)備和人身安全。

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(zhuǎn)嫁給地球，算是一根生命線。
核實接地棒的電壓等級與操作設(shè)備的電壓等級是否一致。

一般在光伏電站中，接地引下線和接地體的電阻很小，多可忽略。系統(tǒng)的接地電阻主要為接地體到大地?zé)o限遠(yuǎn)處的電阻，即主要由接地體周圍的土壤電阻率決定。 土壤電阻率 
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.”

按不同電壓等級選用對應(yīng)規(guī)格的接地線。

掛接地線前必須先驗電，未驗電掛接地線是基層中較普遍的習(xí)慣性違章行為，在懸掛時接地線道體不能和身體接觸。

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種類型：（1）中性點非直接接地方式（I-T）。用電設(shè)備中性點不接入大地，（2）單個保護(hù)接地方式（T-T）。電源變壓器的中性點直接接地，用電設(shè)備外殼可導(dǎo)電部分直接接入大地（3）中性點直接接地方式（T-N）。在這種方式中，電力系統(tǒng)變壓器中性點直接接地，用電設(shè)備外殼可導(dǎo)電部分通過接地引下線和接地系統(tǒng)作良好的金屬性連接，。
