Mukusarudza kugoverwa kwesimba rine simba shoma, vatengi vazhinji vane pfungwa dzisiri dzechokwadi: kana kunzwa kwesimba remagetsi kuchikwiraChinoputsa Current Residual chine dziviriro yeOvercurrent, kushandiswa kwesimba remagetsi kuchava kwakachengeteka. Kutaura zvazviri, chinhu chikuru chekudzivirira magetsi aripo ndechekugadzirisa mamiriro ezvinhu uye kugadzirisa maparameter ehunyanzvi, pane kutsvaga kunzwisisika kwakanyanya.
Nzvimbo dzisinganyanyi kugadzikana dzinogona kukonzera matambudziko nguva nenguva uye kukanganiswa kwemagetsi kusingatarisirwi. Kungofanana chete nematanho ehunyanzvi zvinoenderana nepfungwa dzehunyanzvi hweindasitiri ndiko kunogona kuita kuti tikwanise kuenzana zvakakwana kuchengetedzeka kwemunhu, kugadzikana kwekushanda kwemidziyo uye kuvimbika kwetambo dzemagetsi.
Rated Residual Operating Current (IΔn) ndiyo core setting parameter ye residual current breaker ine overcurrent protection. Mainstream current ratings anosanganisira 30mA, 100mA uye 300mA, uye imwe neimwe ine protection logic yakazvimirira.
Modhi ye30mA ndeyemhando yepamusoro-soro, yakagadzirirwa kudzivirira kuvhunduka kwemagetsi. Mhando dze100mA ne300mA isarudzo dzepakati nepasi dzekudzivirira moto, dzichinyanya kutarisa pakudzivirira moto wemagetsi nemidziyo yemagetsi.
Kana michina ine 30mA ine hutachiona hwakanyanya ikashandiswa nechisimba munzvimbo dzemaindasitiri nedzemabhizinesi dzine hutachiona hwakawanda, kubuda kwemvura kwemidziyo yekushandisa kuchaita kuti magetsi adzime zvisina kufanira uye kumisa magetsi emabhizimisi nekugadzira. Kusiyana neizvi, kuisa ma "low-sensitivity breakers" munzvimbo dzemabhizinesi dzinogara vanhu vakawanda hakukwanisi kudzima magetsi ipapo ipapo panguva yetsaona dzemagetsi, zvichikonzera njodzi huru dzekuchengetedza.
Pfungwa yekusarudza kwehunyanzvi yematanho ekudzivirira asara azvino zvichibva pane zviitiko zvekushandisa yakajeka uye yakajairika:
1.Mamiriro Ekugara Nemagariro Evanhu
Isa zvinhu zvakakosha pakuchengetedza munhu uye shandisa simba remagetsi re30mA. Rakakodzera maseketi e230V single-phase, rinofukidza mwenje, masoketi, kicheni nemabhavhu ekugezera uko vanhu vari nyore kubata zvikamu zvipenyu, zvichiita kuti magetsi adzimwe nekukurumidza kudzivirira njodzi dzemagetsi.
2.Mamiriro Ekutengeserana & Akareruka Emaindasitiri
Kuenzanisa kuchengetedzeka uye kugadzikana kwekushanda ne 100mA setting. Inodzivisa zvinobudirira kukanganiswa kunokonzerwa nekubuda kwemvura kwemidziyo ine simba guru muzvitoro zvikuru nemafekitori madiki, ukuwo ichipa dziviriro yemagetsi yakavimbika pamoto.
3.Mamiriro Ekuparadzira Simba Remaindasitiri Nesimba Rakakura
Tarisa pakudzivirira tambo dzemagetsi nemidziyo ine chiyero che300mA. Yakanakira masisitimu ekugovera magetsi e400V matatu-phase, inochinjika kumaseketi marefu uye mamiriro ekushanda anorema kuti ive nechokwadi chekuti magetsi anogara achiwanikwa uye akagadzikana.
Kuti zvizadzise zvinodiwa pakusarudza zvinoenderana nemamiriro ezvinhu ari pamusoro apa,Vanhu Magetsi RDL8-40 Series RCBOinopa mhinduro yehunyanzvi inoshanda zvizere. Ichitevedzera mitemo yepasi rose yeIEC/EN61009, nhevedzano iyi inotsigira current operating ratio inogadziriswa ye30mA/100mA/300mA, ine current inotangira pa6A kusvika 40A.
Inowanikwa mu1P+N uye 3P+N pole configurations, inoenderana zvizere ne230/400V, 50/60Hz AC neDC power distribution systems. Ichibatanidza overcurrent, short circuit uye residual current triple protection, dhizaini ye electromagnetic inoita kuti nguva yekushanda igare pasi pe 0.1s. Ichishandisa 35mm standard DIN rail mounting kuti ikurumidze kuiswa,RDL8-40 Series RCBOInonyanya kushandiswa pazviitiko zvekugara, zvemabhizinesi uye zvemaindasitiri, ichigadzirisa dambudziko rinowanzo sangana nevanhu vanogumburwa nepfungwa dzakanyanya uye njodzi dzakavanzika dzekuchengetedza dzinobva pakusakwana kwepfungwa.
Kukosha kwekuchengetedzwa kweRCBO yasara yemagetsi inopwanya magetsiHazvimbovi zvinoenderana chete nekunzwa kwakanyanya, asi pakubatanidzwa kwesainzi kwekuenzanisa mamiriro ezvinhu uye kurongeka kwema parameter. Nekugadzirwa kwema parameter ehunyanzvi, People Electric RDL8-40 Series inopa dziviriro yakavimbika yemagetsi asara kune akasiyana mashandisirwo emagetsi, zvichigonesa kusarudzwa kwakarurama uye kushandiswa kwakachengeteka kwemagetsi kune vashandisi vepasi rese.
