JCRD2-125 RCD: Kuchengetedza Hupenyu uye Zvivakwa neKucheka-Edge Kuchengetedzwa Kwemagetsi.

Munguva iyo magetsi azova chikamu chakakosha chehupenyu hwedu hwezuva nezuva, kukosha kwekuchengetedzwa kwemagetsi hakugone kuwedzeredzwa. Nekuwedzera kwekushandiswa kwemidziyo yemagetsi uye masisitimu mune zvese zvekugara uye zvekutengesa, njodzi yenjodzi dzemagetsi inokwirawo. Kuti kuderedze njodzi idzi, vagadziri vakagadzira epamberi magetsi ekuchengetedza maturusi, imwe yacho ndeyeJCRD2-125 RCD(Residual Current Circuit Breaker) - chishandiso chinoponesa hupenyu chakagadzirirwa kuchengetedza vashandisi uye zvivakwa kubva kumagetsi emagetsi uye inogona kuitika moto.

Kunzwisisa iyo JCRD2-125 RCD

Iyo JCRD2-125 RCD ndeye inonzwa yazvino breaker inoshanda pamusimboti wekusara ikozvino kuonekwa. Iyo yakanyatsogadzirirwa kutarisa dunhu remagetsi kune chero kusaenzana kana kukanganisa munzira yazvino. Muchiitiko chekusaenzana kwakaonekwa, sekudonha ikozvino pasi, RCD inokurumidza kutyora dunhu kudzivirira kukuvadza kune vanhu uye kukanganisa pfuma.

Mudziyo uyu unowanikwa mumhando mbiri: Type AC uye Type A RCCB (Residual Current Circuit Breaker ine Integral Overcurrent Protection). Mhando mbiri idzi dzakagadzirirwa kudzivirira kuvhundutsa kwemagetsi uye njodzi dzemoto asi dzinosiyana mumhinduro yadzo kune chaiwo marudzi ezvino.

Tora AC RCD

Type AC RCDs ndiwo anonyanya kuiswa mudzimba. Iwo akagadzirirwa kuchengetedza michina inopikisa, capacitive, kana inductive uye isina chero zvinhu zvemagetsi. Aya maRCD haana nguva yekunonoka uye anoshanda pakarepo pakuona kusaenzana mune alternating sinusoidal residual current.

Nyora A RCD

Type A RCDs, kune rumwe rutivi, inokwanisa kuona ese ari maviri alternating sinusoidal residual current uye residual pulsating direct current kusvika ku6 mA. Izvi zvinoita kuti dzive dzakakodzera maapplication uko yakananga maficha ezvino angave aripo, senge mune renewable magetsi masisitimu kana magetsi emagetsi ekuchaja zviteshi.

Key Features uye Benefits

Iyo JCRD2-125 RCD inozvirumbidza zvakasiyana-siyana zvezvinhu zvinokatyamadza zvinowedzera kushanda kwayo uye kuvimbika. Heano mamwe ezvaanonyanya kukosha:

Earth Leakage Protection:Nekutarisa kuyerera kwazvino, iyo RCD inogona kuona nekubvisa dunhu kana nyika ichidonha, kudzivirira kuvhunduka kwemagetsi uye njodzi dzemoto.

Breaking Capacity: Nekutyoka kweanosvika 6kA, JCRD2-125 inokwanisa kubata yakakwira kukanganisa mafambiro, ichipa dziviriro yakasimba kubva kumaseketi mapfupi uye kuwandisa.

Rated Current Options: Inowanikwa mumhando dzakasiyana siyana dzemazuva ano kubva pa25A kusvika 100A (25A, 32A, 40A, 63A, 80A, 100A), iyoRCDinogona kugadzirwa kuti ienderane nemasisitimu emagetsi akasiyana uye mitoro.

Tripping Sensitivity: Chishandiso chinopa kugumburwa kwekunzwa kwe30mA, 100mA, uye 300mA, ichipa imwe dziviriro kubva pakubata kwakananga, kubatwa zvisina kunanga, uye njodzi dzemoto, zvichiteerana.

Positive Status Indication Contact: Chimiro chakanaka chechiratidzo chekubata chinobvumira kuonesa kuri nyore kweiyo RCD mamiriro ekushanda.

35mm DIN Rail Mounting: Iyo RCD inogona kuiswa pane yakajairwa 35mm DIN njanji, ichipa kugadzika kuchinjika uye nyore kushandisa.

Installation Flexibility: Chishandiso chinopa sarudzo yekubatanidza mutsara kubva kumusoro kana pasi, inogadzirisa zvakasiyana zvekuisa zvido uye zvinodiwa.

Kutevedzera Mitemo: Iyo JCRD2-125 inoenderana neIEC 61008-1 uye EN61008-1 zviyero, kuve nechokwadi kuti inosangana nekuchengetedzwa kwenyika uye kuita zvinodiwa.

Zvido zveTechnical uye Kuita

Kuwedzera kune ayo akakosha maficha, iyo JCRD2-125 RCD inoshamisira inoshamisa tekinoroji zvirevo izvo zvinowedzera kusimudzira kuvimbika kwayo uye kuita kwayo. Izvi zvinosanganisira:

• Rated Working Voltage: 110V, 230V, 240V ~ (1P + N), zvichiita kuti ive yakakodzera kushandiswa mumagetsi akasiyana-siyana.

• Bata Position Indicator: Green=OFF, Tsvuku=ON, ichipa chiratidzo chakajeka chechimiro cheRCD.
• Terminal Connection Type: Cable/Pin-type busbar, inogara mhando dzakasiyana dzekubatanidza magetsi.

Kuedza uye In-Service Kuvimbika

Kuve nechokwadi chekuvimbika kweRCD kwakakosha pakubudirira kwavo mukudzivirira njodzi dzemagetsi. Vagadziri vanoita kuyedza kwakaomarara panguva yekugadzira, inozivikanwa semhando yekuyedza, kuti vaone mashandiro echishandiso pasi pemamiriro akasiyana. Type A, B, uye F RCDs inoyedzwa nenzira imwecheteyo seAC RCD, ine ruzivo rwemaitiro ekuyedza uye nguva dzepamusoro dzekudzima dzakatsanangurwa mumaindasitiri zviyero seIET Guidance Note 3.

Panguva yekuongorora kwemagetsi, kana muongorori akawana Type AC RCD uye achinetsekana nekukanganisika kwezvinosara zveDC ikozvino pakushanda kwayo, vanofanirwa kuzivisa mutengi nezvenjodzi dzingangoitika uye kukurudzira kuongororwa kwehuwandu hweDC yakasara yakashata. Zvichienderana nehuwandu hwekusara kweDC kukanganisa ikozvino, RCD yakapofumadzwa nayo inogona kutadza kushanda, ichiisa njodzi yakakomba yekuchengetedza.

Mhedziso

Muchidimbu, theJCRD2-125 RCDchinhu chakakosha chekuchengetedza magetsi chinopa dziviriro yakazara kubva kumagetsi uye njodzi dzemoto. Hunhu hwayo hwepamberi, hunosanganisira kucherechedzwa kwemagetsi, kuchengetedzwa kwepasi kuvuza, uye yakakura yekupwanya kugona, inoita kuti ive sarudzo yakanaka yekushandisa munzvimbo dzekugara uye dzekutengesa. Nekutevedzera kwayo zviyero zvepasirese uye maitiro akaomarara ekuyedza, JCRD2-125 RCD inopa vashandisi rugare rwepfungwa uye nedanho repamusoro revimbiso yekuchengetedza. Sezvo magetsi achiramba achiita basa rakakosha muhupenyu hwedu hwezuva nezuva, kuisa mari mumidziyo yekuchengetedza yemagetsi epamberi seJCRD2-125 RCD isarudzo ine hungwaru inogona kuponesa hupenyu nekudzivirira zvivakwa kubva kune inoparadza njodzi dzemagetsi.
