R1NRN-ZJD直流(liu)(liu)接(jie)(jie)地故(gu)障(zhang)查找(zhao)儀：電(dian)力直流(liu)(liu)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)接(jie)(jie)地是易發生(sheng)且對(dui)電(dian)力系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)危害較大(da)的(de)故(gu)障(zhang)。直流(liu)(liu)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)正極接(jie)(jie)地，可能造成繼電(dian)保(bao)護(hu)誤動(dong)，因為跳(tiao)閘(zha)線(xian)圈(quan)接(jie)(jie)直流(liu)(liu)電(dian)源負極，可能引起保(bao)護(hu)誤動(dong)；直流(liu)(liu)系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)負極接(jie)(jie)地，可將跳(tiao)閘(zha)回(hui)路或合閘(zha)回(hui)路短路，造成保(bao)護(hu)拒(ju)動(dong)；此(ci)時系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)發生(sheng)故(gu)障(zhang)，保(bao)護(hu)的(de)拒(ju)動(dong)必(bi)然導致系(xi)(xi)(xi)(xi)統(tong)(tong)(tong)事故(gu)擴大(da)，同(tong)時還可能燒壞(huai)繼電(dian)器的(de)觸點或燒保(bao)險。
ZD9608F接(jie)(jie)地故障查找儀：直流(liu)(liu)系(xi)統(tong)(tong)(tong)為控制、保護、信號和自動(dong)裝置提供(gong)(gong)電(dian)源，直流(liu)(liu)系(xi)統(tong)(tong)(tong)的安全連續運行(xing)對保證(zheng)發供(gong)(gong)電(dian)有著很大的重要性。由于直流(liu)(liu)系(xi)統(tong)(tong)(tong)為浮空制的不接(jie)(jie)地系(xi)統(tong)(tong)(tong)，如果(guo)發生兩(liang)點(dian)(dian)接(jie)(jie)地，就可能引(yin)起上述裝置誤(wu)動(dong)、拒動(dong)，從(cong)(cong)而造成重大事故。因此(ci)當(dang)發生一點(dian)(dian)接(jie)(jie)地時，就應在保證(zheng)直流(liu)(liu)系(xi)統(tong)(tong)(tong)正常供(gong)(gong)電(dian)的同時準確迅速地探(tan)測(ce)出(chu)接(jie)(jie)地點(dian)(dian)，排除接(jie)(jie)地故障，從(cong)(cong)而避免兩(liang)點(dian)(dian)接(jie)(jie)地可能帶(dai)來的危害。
