Kukosha kweRudzi rweB RCDs muMazuvano Magetsi Zvishandiso: Kuve nechokwadi chekuchengetedza muAC uye DC Circuits.

Type B Residual Current Devices (RCDs)midziyo yakakosha yekuchengetedza inobatsira kudzivirira kuvhundutswa kwemagetsi nemoto mumasisitimu anoshandisa direct current (DC) kana ane masaisai emagetsi asiri akajairwa. Kusiyana nemaRCD enguva dzose anongoshanda nealternating current (AC), Type B RCDs inokwanisa kuona nekumisa zvikanganiso mumaseketi ese eAC neDC. Izvi zvinoita kuti zvive zvakakosha pakushandisa magetsi matsva semagetsi emagetsi ekuchaja zviteshi, solar panel, wind turbines, uye zvimwe midziyo inoshandisa DC magetsi kana ine mafungu emagetsi asina kujairika.

Type B RCDs inopa dziviriro iri nani uye chengetedzo mumasisitimu emagetsi emazuva ano uko DC uye mafungu asina-standard akajairika. Iwo akagadzirwa kuti adzime otomatiki magetsi kana aona kusaenzana kana kukanganisa, kudzivirira mamiriro angangoita njodzi. Sezvo kudiwa kwemasisitimu emagetsi anogona kudzokororwa uye mota dzemagetsi dzichiramba dzichikura, Type B RCDs dzave kukosha pakuona kuchengetedzeka kweaya matekinoroji matsva. Vanobatsira kudzivirira kuvhundutswa kwemagetsi, moto, uye kukuvadzwa kwemidziyo yakaoma nekukurumidza kuona uye kumisa chero kukanganisa muhurongwa hwemagetsi. Pakazere, Type B RCDs kufambira mberi kwakakosha mukuchengetedzwa kwemagetsi, kubatsira kuchengetedza vanhu nemidziyo munyika nekuwedzera kushandiswa kwesimba reDC uye masaisai emagetsi asiri akajairwa.

Zvimiro zve JCRB2-100 Rudzi rweB RCDs

Iyo JCRB2-100 Type B RCDs maturusi epamberi ekuchengetedza magetsi akagadzirirwa kupa dziviriro yakazara kubva kumhando dzakasiyana dzekukanganisa mumasisitimu emagetsi emazuva ano. Zvimiro zvavo zvakakosha zvinosanganisira:

Kufamba Sensitivity: 30mA

Iko kugumbuka kwekunzwa kwe30mA paJCRB2-100 Type B RCDs zvinoreva kuti mudziyo unozodzima magetsi ega kana ukaona kubuda kwemagetsi kunosvika makumi matatu emamilimita (mA) kana kupfuura. Iyi nhanho yekunzwa yakakosha pakuona yakakwira mwero wedziviriro kubva kune inogona kuitika magetsi kana moto unokonzerwa nekutadza kwepasi kana kuvuza kwemvura. Kubuda kwe30mA kana kudarika kunogona kuve nengozi zvakanyanya, zvichigona kukonzera kukuvara kwakanyanya kana kufa kana kukasiiwa. Nekugumburwa panguva iyi yakaderera yekudonha, iyo JCRB2-100 inobatsira kudzivirira mamiriro ane njodzi akadaro kuti asaitike, nekukasira kucheka simba kutadza kusati kwakonzera kukuvadza.

2-Pole / Single Phase

Iyo JCRB2-100 Type B RCDs dzakagadzirwa se 2-pole zvishandiso, zvinoreva kuti dzakagadzirirwa kushandiswa mune imwechete-chikamu masisitimu emagetsi. Single-phase masisitimu anowanzo kuwanikwa mudzimba dzekugara, mahofisi madiki, uye zvivakwa zvakareruka zvekutengesa. Mune izvi zvigadziriso, imwe-chikamu simba rinowanzo shandiswa pakugonesa magetsi, midziyo, uye mamwe madiki madiki emagetsi. Iyo 2-pole kumisikidzwa yeJCRB2-100 inobvumira kuti itarise nekudzivirira ese ari maviri mhenyu uye asina kwaakarerekera conductors muchikamu chimwe-chikamu chedunhu, kuve nechokwadi chekuchengetedzwa kwakazara kubva pane kukanganisa kunogona kuitika pane chero mutsara. Izvi zvinoita kuti mudziyo unyatsokodzera kuchengetedza imwe-chikamu kuisirwa, uko kwakawanda munzvimbo dzakawanda dzemazuva ese.

Chiyero chezvino: 63A

Iyo JCRB2-100 Rudzi rweB RCDs ine chiyero chazvino che63 amps (A). Chiyero ichi chinoratidza huwandu hwemagetsi emagetsi anogona kushandiswa zvakachengetedzeka pasi pemamiriro ekushanda pasina kugumburwa kana kuremerwa. Mune mamwe mazwi, iyo JCRB2-100 inogona kushandiswa kuchengetedza maseketi emagetsi ane mitoro inosvika 63 amps. Ichi chiyero chemazuva ano chinoita kuti chigadziro chikodzere kune zvakasiyana-siyana zvekugara uye chiedza chekutengesa zvikumbiro, apo mitoro yemagetsi inowanzowira mukati meiyi. Nekudaro, zvakakosha kuti uzive kuti kunyangwe iyo yazvino iri mukati meiyo 63A chiyero, iyo JCRB2-100 icharamba ichifamba kana ikaona kubuda kwe30mA kana kupfuura, sezvo iyi iri nhanho yekunzwa yekudzivirira kukanganisa.

Voltage Rating: 230V AC

Iyo JCRB2-100 Type B RCDs ine voltage rating ye230V AC. Izvi zvinoreva kuti akagadzirwa kuti ashandiswe mumasisitimu emagetsi anoshanda pamhepo yezita re230 volts alternating current (AC). Iyi voltage rating yakajairika munzvimbo zhinji dzekugara uye dzakareruka dzekutengesa, zvichiita iyo JCRB2-100 yakakodzera kushandiswa munzvimbo idzi. Zvakakosha kuziva kuti mudziyo haufanire kushandiswa mumasisitimu emagetsi ane mavoltages akakwira kupfuura iwo akayerwa voltage, sezvo izvi zvinogona kukanganisa mudziyo kana kukanganisa kugona kwayo kushanda nemazvo. Nekuomerera kune 230V AC voltage rating, vashandisi vanogona kuve nechokwadi chekuti JCRB2-100 ichashanda zvakachengeteka uye zvinobudirira mukati meiyo yainoda voltage renji.

Short-Circuit Current Capacity: 10kA

Iyo pfupi-yedunhu ikozvino kugona kweJCRB2-100 Type B RCDs ndeye gumi kiloamps (kA). Chiyero ichi chinoreva huwandu hwehuwandu hwepfupi-sekiti ikozvino iyo mudziyo unogona kumira nayo isati yagona kuchengetedza kukuvara kana kutadza. Short-circuit currents inogona kuitika mumasisitimu emagetsi nekuda kwekukanganisa kana mamiriro asina kujairika, uye anogona kunge akakwira zvakanyanya uye anogona kuparadza. Nekuva nepfupi-yedunhu ikozvino kugona kwe10kA, iyo JCRB2-100 yakagadzirirwa kuramba ichishanda uye nekupa dziviriro kunyangwe paine chiitiko chakakosha chepfupi-yedunhu kukanganisa, kusvika ku10,000 amps. Ichi chiitiko chinovimbisa kuti chigadziro chinogona kuchengetedza zvakasimba hurongwa hwemagetsi uye zvikamu zvaro muchiitiko chekukanganisa kwakadaro kwepamusoro-ikozvino.

IP20 Dziviriro Rating

IJCRB2-100 Rudzi rweB RCDs ine IP20 yekudzivirira chiyero, iyo inomiririra "Ingress Protection" chiyero che 20. Ichi chinyorwa chinoratidza kuti chigadzirwa chinodzivirirwa pazvinhu zvakasimba zvakakura kudarika 12.5 millimeters muhukuru, zvakadai seminwe kana zvishandiso. Zvisinei, haipe dziviriro pamvura kana zvimwe zvinwiwa. Nekuda kweizvozvo, iyo JCRB2-100 haina kukodzera kushandiswa kwekunze kana kuisirwa munzvimbo iyo inogona kuratidzwa nehunyoro kana zvinwiwa pasina kumwe kudzivirirwa. Kuti ushandise mudziyo munzvimbo dzekunze kana dzakanyorova, inofanirwa kuiswa mukati memuvharo wakakodzera unopa dziviriro inodiwa pamvura, guruva, uye zvimwe zvakatipoteredza.

Kuteerana neIEC/EN 62423 uye IEC/EN 61008-1 Mitemo

Iyo JCRB2-100 Type B RCDs akagadzirwa uye anogadzirwa zvinoenderana nemitemo miviri yakakosha yenyika: IEC/EN 62423 uye IEC/EN 61008-1. Aya mazinga anotsanangura zvinodikanwa uye maitiro ekuyedza eResidual Current Devices (RCDs) anoshandiswa mune yakaderera-voltage kuisirwa. Kutevedzera mitemo iyi kunovimbisa kuti JCRB2-100 inosangana nekuchengetedzwa kwakasimba, kushanda, uye mazano ehutano, kuvimbisa chiyero chakafanana chekudzivirira uye kuvimbika. Nekuomerera kune aya anozivikanwa mazinga, vashandisi vanogona kuve nekuvimba mukugona kwechishandiso kushanda sezvakarongwa uye nekupa dziviriro dzinodiwa pakukanganisa kwemagetsi nenjodzi.

Pakazere, iyo JCRB2-100 Type B RCDs inopa yakawedzera chengetedzo uye kuvimbika, ichivaita chinhu chakakosha mukugara, kutengeserana, uye maindasitiri emagetsi ekuisa.

FAQ

1.Chii chinonzi Type B RCD?

Type B RCDs haifanire kuvhiringika neType B MCBs kana RCBOs dzinoonekwa mumawebhusaiti akawanda.

Type B RCDs dzakasiyana zvachose, zvisinei, zvinosuruvarisa kuti tsamba imwe chete yakashandiswa iyo inogona kutsausa. Kune Rudzi B runova hunhu hwekupisa muMCB/RCBO uye Rudzi B runotsanangura maitiro emagineti muRCCB/RCD. Izvi zvinoreva kuti saka uchawana zvigadzirwa zvakaita seRCBOs zvine maitiro maviri, zvinoti magineti eRCBO uye thermal element (iyi inogona kunge iri Type AC kana A magineti uye Type B kana C inopisa RCBO).

2.Type B RCDs inoshanda sei?

Type B RCDs dzinowanzo gadzirwa nemasisitimu maviri asara ekuona. Yekutanga inoshandisa tekinoroji ye 'fluxgate' kugonesa iyo RCD kuona yakatsetseka DC ikozvino. Yechipiri inoshandisa tekinoroji yakafanana neType AC uye Type A RCDs, inova voltage yakazvimirira.
