上海勝緒電(dian)(dian)(dian)(dian)(dian)氣防雷等電(dian)(dian)(dian)(dian)(dian)位測(ce)試(shi)儀廣泛應(ying)用于電(dian)(dian)(dian)(dian)(dian)信、電(dian)(dian)(dian)(dian)(dian)力、氣象(xiang)、機房、油田、電(dian)(dian)(dian)(dian)(dian)力配電(dian)(dian)(dian)(dian)(dian)線路、鐵(tie)塔(ta)輸電(dian)(dian)(dian)(dian)(dian)線路、加油站、工廠接(jie)地網(wang)、避雷針(zhen)等。還具備測(ce)量直流電(dian)(dian)(dian)(dian)(dian)壓和交流電(dian)(dian)(dian)(dian)(dian)壓功能。

3A抗干擾異頻地(di)網接地(di)阻抗測試儀(yi)測試電(dian)(dian)流(liu)(liu)為0.0A時候(hou)，可能“電(dian)(dian)流(liu)(liu)線”連線與“電(dian)(dian)流(liu)(liu)極”地(di)樁(zhuang)(zhuang)接觸不良或地(di)樁(zhuang)(zhuang)太少(shao)，需增加地(di)樁(zhuang)(zhuang)，減少(shao)回路(lu)電(dian)(dian)阻。地(di)樁(zhuang)(zhuang)深度不少(shao)于(yu)0.5m。電(dian)(dian)流(liu)(liu)樁(zhuang)(zhuang)電(dian)(dian)阻應該小于(yu)200Ω.

異頻(pin)接地(di)(di)阻(zu)抗測試儀介紹(shao)：設(she)備測量結(jie)果(guo)由大屏幕液晶顯示，自帶微型打印機(ji)可打印輸出。適用(yong)于發(fa)電(dian)廠(chang)、變電(dian)站(zhan)、配電(dian)站(zhan)、建筑(zhu)物等在建或(huo)運(yun)行接地(di)(di)系(xi)統的測試。

防雷異頻接(jie)地電(dian)(dian)(dian)阻測(ce)試儀檢測(ce)時(shi)候，必須在C1輸(shu)出(chu)端串接(jie)20歐以(yi)上的電(dian)(dian)(dian)阻，用來模擬現場電(dian)(dian)(dian)流樁電(dian)(dian)(dian)阻，否則(ze)有(you)可能造(zao)成測(ce)量數(shu)據誤(wu)差偏大。

大型接(jie)地網(wang)接(jie)地阻抗(kang)測(ce)量儀自帶微型打印(yin)(yin)機可打印(yin)(yin)輸出。適用于發(fa)電(dian)廠、變電(dian)站(zhan)、配電(dian)站(zhan)、建(jian)筑(zhu)物等在建(jian)或運行接(jie)地系(xi)統的測(ce)試。

異頻(pin)(pin)法的(de)大型接(jie)地網接(jie)地電(dian)阻測試(shi)儀測量的(de)工頻(pin)(pin)等效(xiao)性好。測試(shi)電(dian)流波(bo)(bo)形為(wei)正弦(xian)波(bo)(bo)，頻(pin)(pin)率僅與工頻(pin)(pin)相(xiang)差為(wei)5Hz，使用 45Hz 和(he)55Hz 兩種頻(pin)(pin)率進行測量。

變(bian)頻大型(xing)地網(wang)接地特性(xing)測量系統(tong)可測量電流樁，電壓樁，接地電阻、輔(fu)助(zhu)機、土壤(rang)電阻率(lv)。全(quan)中文菜(cai)單式操作，直接顯示出測量結(jie)果。

防雷大地網接地電阻測試儀(yi)精(jing)度高(gao)。基本誤(wu)差(cha)僅0.005Ω，可用來(lai)測量接地阻抗很小(xiao)的大型地網。
