系(xi)统(tong)发生(sheng)单相(xiang)接地故障(zhang)时，接地电(dian)(dian)容(rong)电(dian)(dian)流很大，采用电(dian)(dian)阻接地方式可以降(jiang)低配电(dian)(dian)设(she)备的绝缘水平，降(jiang)低电(dian)(dian)网的投(tou)资。

中性点经电(dian)阻接(jie)(jie)地方式在发生单相接(jie)(jie)地故障时(shi)与保护相配合快速切除故障线路，抑制(zhi)谐振过电(dian)压，提(ti)高了电(dian)力系统的安全性以及可靠(kao)性。

KA2003-ZR电(dian)(dian)阻柜系(xi)列由(you)丹华(hua)自(zi)主研发，分(fen)为变压器中(zhong)性(xing)点和发电(dian)(dian)机(ji)中(zhong)性(xing)点两(liang)种类型(xing)(xing)，广泛应(ying)用于城市配(pei)(pei)电(dian)(dian)网(wang)、风电(dian)(dian)厂、火电(dian)(dian)厂、大型(xing)(xing)钢(gang)厂等配(pei)(pei)网(wang)系(xi)统(tong)。
