Udindo Wofunikira wa JCR2-125 Residual Current Devices (RCDs) mu Elec

It ndichifukwa chake chitetezo chamagetsi nthawi zambiri chimakhala chokwera kwambiri padziko lonse lapansi laukadaulo. Mabwalo amagetsi amatha kukhala othandiza pazifukwa zosiyanasiyana pagulu koma amabweranso ndi zoopsa zosiyanasiyana zomwe zitha kuzindikirika ngati sizikuthandizidwa bwino. Ili ndiye gawo lomwe amaseweraZida Zotsalira Zamakono (RCDs)ndi Zotsalira Zatsopano Zapakhomo (RCCBs). Izi zimapangidwira kuteteza anthu ndi katundu ku zoopsa zamagetsi mwa kudula dera mofulumira pamene gawo losavomerezeka kapena kutayikira kulipo. Chitsanzo chimodzi cha chipangizo choterocho ndiChithunzi cha JCR2-125, zomwe zapangidwa mwadala ndi kupangidwa kuti zichepetse mwayi wolandira kugwedezeka kwamagetsi kwakupha ndikuchepetsa kuopsa kwa moto wamagetsi.

Kumvetsa Chithunzi cha JCR2-125

JCR2-125 RCD ndi chipangizo chamagetsi chomwe chimakhala chaukadaulo kwambiri popeza ntchito yake yayikulu ndikuwunika mafunde akutuluka kuti ateteze ogwiritsa ntchito. Ngati pali kutayikira pakali pano zikutanthauza kuti gawo lina la mayeso likuyambitsa njira zomwe sizimayembekezereka monga kudzera m'thupi kapena kuwonongeka kwa insulation. JCR2-125 imapangidwa makamaka kuti ichoke mudera muzochitika monga njira yodzitetezera ku kuvulala kapena kutayika.

Zina zazikulu za JCR2-125 RCD wophwanya dera latsopano akufotokozedwa motere:

JCR2-125 RCD imabwera ndi zinthu zingapo zofunika kwambiri zomwe zimapangitsa kuti ikhale yogwira mtima komanso yodalirika pakuwonetsetsa chitetezo chamagetsi: JCR2-125 RCD imabwera ndi zinthu zingapo zofunika kwambiri zomwe zimapangitsa kuti ikhale yogwira mtima komanso yodalirika pakuwonetsetsa chitetezo chamagetsi:

Mtundu wa Electromagnetic:Imawonetsetsanso kuti pali kuthyoka mwachangu komanso moyenera kwa dera pomwe mafunde akutuluka azindikirika.

Chitetezo cha Earth Leakage:Amachepetsa chiopsezo cha kuwonongeka kwa magetsi zomwe zingayambitse kugwedezeka kwa magetsi kapena moto.

Kuthamanga Kwambiri:Ili ndi mphamvu yosweka mpaka 6kA, yomwe imapangitsa kuti ikhale yokhoza kusokoneza osati kudzera pamakono abwino komanso vuto lalikulu panthawi imodzimodzi popanda kuwonongeka.

Zambiri Zovotera:Zopezeka mumitundu yosiyanasiyana monga 25 amps, 32 amps, 40 amps, 63 amps, 80 amps, ndi 100 amps zimayiyika pamalo ogwirira ntchito zosiyanasiyana.

Kukhudzika Kwapaulendo:Zotulutsa zitatu zomwe ndi 30mA, 100mA, ndi 300mA kuti zikwaniritse zofunikira zachitetezo pakutuluka kuchokera pazida.

Kutsata Miyezo:Imatsatira zofunikira za kudalirika ndi chitetezo cha IEC 61008-1 ndi EN61008-1.

Positive Status Indication Contact:N'zotheka kugwiritsa ntchito zizindikiro zomveka bwino komanso zosavuta kuzizindikira zogwirizana ndi momwe chipangizocho chikuyendera.

Kusinthasintha kwa kukhazikitsa:Itha kukhazikitsidwa ku njanji ya 35mm DIN ndipo ili ndi mwayi wolumikizidwa pamwamba kapena pansi, ndikupangitsa kuti ikhale yosavuta kuyiyika.

Mapangidwe Amphamvu:Imakhala ndi moyo wogwiritsa ntchito nthawi 2000 komanso nthawi yogwiritsa ntchito magetsi nthawi 2000, chifukwa cha mbali zonse ziwiri komanso moyo wothandiza.

Mu kafukufukuyu, pali ma RCD osiyanasiyana, ndipo pansipa pali mitundu ya ma RCD ndi ntchito zawo.

Mitundu yosiyanasiyana yapano yotsalira imagwiritsidwa ntchito kugawa ma RCD kutengera kukhudzika kwawo. JCR2-125 imapereka mitundu yonse ya AC ndi Type A RCDs, iliyonse yoyenerera kugwiritsa ntchito: JCR2-125 imapereka mitundu yonse ya AC ndi Type A RCDs, iliyonse yoyenera kugwiritsa ntchito:

Lembani AC RCDs

Pomaliza, lolani mtundu wa AC RCDs uzindikire sinusoidal residual alternating current. Izi zimapezeka nthawi zambiri m'nyumba zotetezera zida zomwe sizingagwirizane, zolimba, kapena zogwiritsa ntchito popanda kugwiritsa ntchito zamagetsi. Amapewa kugwedezeka mopitilira muyeso komanso amapereka chiwongolero chanthawi yomweyo pakangowoneka kusalinganika.

Lembani A RCDs

Pomwe Type A RCDs imatha kuzindikira ma sinusoidal residual current komanso ma residual pulsating direct current ang'ono ngati 6mA yapano pa AC frequency. Izi zimawapangitsa kukhala oyenera kugwiritsidwa ntchito pomwe zida zamagetsi zimakhudzidwa makamaka pamayendedwe ovuta amagetsi popeza amapereka chitetezo chabwinoko pamakina otere poyerekeza ndi mitundu ina ya zopinga.

Kufunika kwa Kukhudzidwa Kwapaulendo

RCD tripping sensitivity imatanthawuza kuthekera kwa RCD kuyankha ku cholakwika chomwe chidayambitsa njira yoyambira, mkati mwa nthawi inayake. JCR2-125 imapereka magawo atatu okhudzidwa: JCR2-125 imapereka magawo atatu okhudzidwa:

30mA: Imavomereza njira zina zodzitchinjiriza kuti zisakhudzidwe mwachindunji ndi magawo amoyo, zomwe zimapangitsanso zida kukhala zabwino pachitetezo chamunthu payekha.

100mA: Zogwirizana ndi dongosolo la dziko lapansi kuti mupewe kuwopseza kukhudza kwachindunji ndikuchepetsa ngozi yokhudzana ndi moto wamagetsi.

300mA: Imateteza kukhudzanso kachiwiri ndipo ndiyothandiza kwambiri poteteza moto woyambitsidwa ndi magetsi.

Mfundo Zaukadaulo za JCR2-125

Mafotokozedwe aukadaulo a JCR2-125 amapangidwa kuti awonetsetse kuti magwiridwe antchito ndi chitetezo chokwanira pamagwiritsidwe osiyanasiyana: Zosintha zaukadaulo za JCR2-125 zimapangidwira kuti zitsimikizire magwiridwe antchito komanso chitetezo chokwanira pamagwiritsidwe osiyanasiyana:

Idavoteredwa Panopa: Itha kupezeka m'miyeso yotsika ngati 25A ndikufika ku 100A yokwera kwambiri pamasinthidwe apano.

Mphamvu yamagetsi Yogwira Ntchito: Imayezera 110V, 230V, ndi 240V pazosowa zapadera zadera kapena kutengera mphamvu yadera yomwe ikufunika.

Kukhudzika Kwambiri: Amabwera m'mitundu yosiyanasiyana ya mafunde monga 30mA, 100mA, ndi 300mA kuti agwirizane ndi chitetezo chomwe chikufunika.

Kuphwanya Mphamvu: Kuwonongeka kwaposachedwa mpaka 6kA kumatha kudutsa gawo lake.

Insulation Voltage: 500V resistor yokhala ndi kutchinjiriza koyenera malinga ndi miyezo ya VCR.

Ma frequency ovotera: Simangogwiritsidwa ntchito pa 50/60Hz.

Impulse Withstand Voltage: Imatha kupirira mpaka 6kV, zomwe zimakhala zopindulitsa pakakwera magetsi.

Digiri ya Chitetezo: Osatchulidwa komanso ofooka kwambiri okhala ndi chitetezo cha IP cha 20 chokha chomwe chimatanthawuza kuti chimangoteteza ku tizigawo ta zolimba ndi fumbi.

Kutentha Kozungulira: Imatha kugwira ntchito pansi pa kutentha kwa -5 madigiri centigrade kukwera mpaka kutentha kwa madigiri 40 centigrade motero imatha kumadera.

Chizindikiro cha Malo Olumikizirana: Chimapereka chizindikiro chomveka bwino cha momwe chipangizocho chilili, ndiye kuti, ON kapena ayi powunikira kapena kung'anima magetsi amtundu wofiyira, motsatana pomwe chobiriwiracho ndi chowonetsa mawonekedwe oyimilira.

Pomaliza, JCR2-125 RCD ngati chipangizo choyambirira chimagwiritsidwa ntchito masiku ano pachitetezo chamagetsi. Ndikofunikira makamaka pakutha kwake kusiyanitsa mwachangu mabwalo omwe amakhala ndi mafunde akuchucha omwe amabweretsa chiopsezo cha electrocution komanso zoopsa zamoto. Chifukwa cha magwiridwe antchito angapo a JCR2-125, monga mafunde osiyanasiyana ovotera, kusweka kwakukulu, komanso kutsata miyezo yapadziko lonse lapansi, imapereka chitetezo chokwanira ku malo okhala, mabizinesi, ndi mafakitale.

Choncho, mitundu yosiyanasiyana yaZithunzi za RCDsndi kuzindikira kusiyana pakati pawo n'kofunika kuti athe kuzindikira chipangizo chogwiritsidwa ntchito kwambiri pazochitika zinazake. Ukhale Mtundu wa AC pazosowa zatsiku ndi tsiku kapena Mtundu A wamadera omwe amafunikira chitetezo chambiri, JCR2-125 ndiyabwino osati kungoteteza katundu wanu komanso kupereka chitetezo kwa ogwiritsa ntchito. Chifukwa chake, kugwiritsa ntchito zida zopita patsogolo zotere kumathandizira kuchepetsa ziwopsezo zomwe zimabwera kuchokera kumagetsi amagetsi ndikuwongolera momwe zinthu zilili komanso ntchito.
