                                                                                                                                                                                                              一般大樓接地結構構成是:接地網引出接地極,接地極連接到接地匯流排,各設備接地連接到接地匯流排上。

                                                                                                                                                                                                              設備的接地電阻應包括:接地網電阻,設備接地點到地網接地極之間匯流排的電阻和個接地之間接觸電阻。因此測量設備的接地電阻要求對三部分都測量,下面就對著三部分測試方案進行說明:

                                                                                                                                                                                                              1

                                                                                                                                                                                                              地網接地電阻測量

                                                                                                                                                                                                              該接地電阻測量點要選擇地網任何一個接地引上極或地網接地電阻測量點進行測量,測量方法采用三極或四極測量方法,如無法布置輔助地極,則可以想辦法采用無輔助地級測量方法,下面是三/四極測量方法實際圖:

                                                                                                                                                                                                              測試原理圖:

                                                                                                                                                                                                              測量時要注意的是:布置輔助地極要注意地勢差的影響,同時要注意輔助地級下面是否有其他金屬或者輔助地級離開地網。如無法布置輔助地級,則采用無輔助地極方法:
                                                                                                                                                                                                              NO.2

                                                                                                                                                                                                              過度電阻即設備接地點到地網接地極之間匯流排的電阻測量,采用儀器的交流電族或直流電阻測量功能進行測試,需要注意的是測量磁電阻,測量電流需要大于100mA。實際測量圖如下:

                                                                                                                                                                                                              NO.3

                                                                                                                                                                                                              接觸電阻即各地極之間接觸電阻測量,測量方法與以上相同,因此往往將一同被進行計算。

                                                                                                                                                                                                              三項結束之后,把測量值加在一起,就是測量結果。
