由SD-ZB□系列剩余電流動(dòng)作保護(hù)繼電器和零序電流互感器組合,構(gòu)成接地故障保護(hù)裝置,適用于TN、TT和IT電網(wǎng)系統(tǒng)。通過(guò)接地電流互感器檢測(cè)出接地零序漏電電流,經(jīng)剩余電流動(dòng)作保護(hù)繼電器與設(shè)定值的比較和判別,及時(shí)發(fā)出動(dòng)作信號(hào),接通或斷開報(bào)警回路,以避免事故的擴(kuò)大,從而保證人員及設(shè)備的安全。
The combination of SD-ZB□ series residual current transformer and zero sequence current protection relay forms ground fault protection device, it applies to TN,TT and IT power system. Via the ground current transformer to detect the ground leak current, the current protection relay compares the sensed current with the setting value and issues operating signal timely, make or break the alarm circuit, to avoid the accident, ensure the safety of personnel and equipment.
