Voltage type leakage circuit breaker ye low voltage neutralgrounding ye transformer.Iyo utility modhi inoratidzwa pakuti kana munhu arohwa nemagetsi, simba rakati wandei rinogadzirwa pamutsetse we zero kuenda pasi, zvichiita kuti relay ifambe, uye switch yemagetsi inogumburwa.
Yazvino mhando yasara yemazuva ano yedunhu breaker inonyanya kushandiswa kune kwayakarerekera point earthing yakaderera-voltage yekugovera sisitimu yetransformer.Mutevedzeri wekushandisa unoratidzwa pakuti kana munhu awana kuvhunduka kwemagetsi, kubuda kwemvura kunowanikwa ne zero sequence current transformer, kuitira kuti relay ishandiswe uye simba rekushandura rinodzimwa.
Residual current (leakage) dziviriro, giya remazuva ano rinosara rinogona kugadziriswa pamhepo, uye mhando dzakanonoka uye dzisina kunonoka dzinogona kusarudzwa pamadiro;
● nebasa rekutanga rekuvhara;
● Automatic tracking, kugadzirisa otomatiki kwegiya maererano neyakasara ikozvino yemutsara, kuve nechokwadi chekumisikidza chiyero uye kuvimbika kwechigadzirwa;
● Kunonoka kwenguva refu, kunonoka-kunonoka uye pakarepo kuchengetedzwa kwematanho matatu, ikozvino inogona kuiswa, nemagetsi decoupling, yakasununguka pamagetsi emagetsi;
● High breaking capacity kuti ive nechokwadi chekuvimbika kwemutsara wekudzivirira kupfupi wedunhu;
● High-current instantaneous decoupling function, apo mhepo inoputika yakavharwa uye inosangana nepfupi-circuit high current (≥20Inm), iyo inoputika inoparadzaniswa zvakananga ne.
electromagnetic decoupler mechanism inoparadzaniswa zvakananga;
● Kudzivirira kwepamusoro-voltage, kuchengetedzwa kwepasi-voltage, kuchengetedzwa kwechikamu chekukundikana;
● Leakage isiri-disconnecting alarm output function;
Iyo RDX2LE-125 RCBO s yakagadzirirwa kuve nechokwadi chekuchengetedzwa kweakadzika-voltage magetsi ekushandisa kusvika ku125A.
