Kuve nechokwadi Chekuchengetedza Kwakaringana muDC Circuit Breakers

Mumunda wemagetsi emagetsi, kuchengetedza nguva dzose ndiyo inonyanya kukosha.Sezvo kudiwa kwesimba rinodzokororwa kuri kuramba kuchikura, kushandiswa kweiyo yakananga ikozvino (DC) kuri kuwedzera kuwanda.Nekudaro, shanduko iyi inoda varindi vane hunyanzvi kuti vave nechokwadi chekuchengetedzwa kwevashandi nemidziyo.Mune ino blog post, isu tichaongorora zvakakosha zvikamu zve aDC circuit breakeruye kuti vanoshanda sei pamwe chete kuti vape dziviriro yakavimbika.

1. AC terminal leakage yekudzivirira mudziyo:
Iyo AC yedivi reDC wedunhu breaker yakashongedzerwa neyakasara yazvino mudziyo (RCD), inozivikanwawo seyasara yazvino wedunhu breaker (RCCB).Chishandiso ichi chinotarisisa mafambiro aripo pakati pewaya mhenyu uye isina kwayakarerekera, ichiona kusaenzana kupi zvako kunokonzerwa nekukanganisa.Kana kusaenzana uku kwaonekwa, iyo RCD inokurumidza kukanganisa dunhu, ichidzivirira njodzi yekuvhunduka kwemagetsi uye kuderedza kukuvadza kunogona kuitika kune system.

2. Iyo DC terminal kukanganisa inopfuura nepa detector:
Tendeukira kudivi reDC, shandisa yakashata chiteshi detector (insulation yekutarisa mudziyo).Iyo detector inoita basa rakakosha mukuenderera mberi kwekutarisa kwemagetsi system insulation kuramba.Kana kukanganisa kukaitika uye kudzivirira kwekudzivirira kunodonha pazasi pechikumbaridzo chakafanotemerwa, chinokanganisa chiteshi chinoongorora chinokurumidza kuziva chikanganiso uye chinotangisa chiito chakakodzera kubvisa chikanganiso.Nguva dzekupindura dzekukurumidza dzinoita kuti kutadza kuwedzere, kudzivirira njodzi dzinogona kuitika uye kukuvara kwemidziyo.

3. DC terminal yekumisa inodzivirira yedunhu breaker:
Kuwedzera kune yekukanganisa chiteshi detector, iyo DC divi reDC wedunhu breaker ine zvakare yakashongedzerwa ine ivhu rekudzivirira redunhu breaker.Ichi chikamu chinobatsira kuchengetedza sisitimu kubva kune zvikanganiso zvine chekuita nepasi, senge kuputsika kwekudzivirira kana kukwirisa kunokonzerwa nemheni.Kana chikanganiso chikaonekwa, iyo pasi yekudzivirira yedunhu breaker inovhura otomatiki dunhu, inonyatso bvisa chikamu chinokanganisa kubva kuhurongwa uye kudzivirira imwe kukuvara.

Kurumidza kugadzirisa dambudziko:
Nepo DC mabreaker edunhu achipa dziviriro yakasimba, zvakakosha kucherechedza kuti kukurumidza kuita pasaiti kwakakosha pakugadzirisa matambudziko.Kunonoka kugadzirisa kukanganisa kunogona kukanganisa kushanda kwemidziyo yekudzivirira.Nokudaro, kugadzirisa nguva dzose, kuongorora, uye kupindura nokukurumidza kune chero chiratidzo chekukundikana kwakakosha kuti uve nechokwadi chekuenderera mberi kwekuvimbika kwegadziriro.

Mitemo yekudzivirira yezvikanganiso zviviri:
Izvo zvakakosha kuti unzwisise kuti kunyangwe iine izvi zvinodzivirira zvinoriumba zviripo, DC wedunhu breaker inogona kusave nechokwadi chekudzivirirwa kana paine kaviri kukanganisa.Kukanganisa kaviri kunoitika kana kukanganisa kwakawanda kuchiitika panguva imwe chete kana mukukurumidza kutevedzana.Kuoma kwekukurumidza kubvisa zvikanganiso zvakawanda kunopa matambudziko kumhinduro inoshanda yezvidziviriro masisitimu.Naizvozvo, kuve nechokwadi chekugadzirisa dhizaini, kuongororwa nguva dzose, uye matanho ekudzivirira anodiwa kuti uderedze kuitika kwekutadza kwakapetwa kaviri.

Muchidimbu:
Sezvo tekinoroji dzesimba remagetsi dzichiramba dzichishanduka, kukosha kwematanho ekudzivirira akakodzera senge DC mabreaker edunhu haagone kusimbiswa.Iko kusanganiswa kweAC side residual current device, DC side fault channel detector uye ground protection circuit breaker inobatsira kuvandudza kuchengetedzwa kwese uye kuvimbika kwemagetsi.Nekunzwisisa basa rezvikamu izvi zvakakosha uye nekukurumidza kugadzirisa kukanganisa, tinogona kugadzira yakachengeteka magetsi enzvimbo kune wese anobatanidzwa.
