2 Pole RCD yotsalira yotsalira yamtundu wa AC kapena Type A RCCB JCRD2-125

JCR2-125 RCD ndi chophwanya tcheru chamakono chomwe chimapangidwira kuteteza wogwiritsa ntchito ndi katundu wawo ku mphamvu yamagetsi ndi moto womwe ukhoza kuchitika pophwanya zomwe zikuchitika momwe zimadutsa pa bokosi la ogula / gawo logawa pakakhala kusalinganika kapena kusokonezeka kwa njira yamakono.

Pemphani Mawu Mwachangu

Tsatanetsatane wa Zamalonda

Chiyambi:

Chida chotsalira-current (RCD), residual-current circuit breaker (RCCB) ndi chipangizo chotetezera magetsi chomwe chimathyola mwachangu dera lamagetsi ndikutayikira pansi.Ndiko kuteteza zida ndi kuchepetsa chiopsezo cha kuwonongeka kwakukulu kwa kugwedezeka kwamagetsi kosalekeza.Kuvulala kungachitikebe nthawi zina, mwachitsanzo ngati munthu alandira kugwedezeka kwakanthawi dera lamagetsi lisanakhazikike, kugwa pambuyo pochita mantha, kapena ngati munthuyo agwira ma conductor onse awiri panthawi imodzi.

JCR2-125 adapangidwa kuti azitha kulumikiza dera ngati pali kutayikira pano.

Zipangizo zamakono za JCR2-125 Zotsalira (RCDs) zimakutetezani kuti musalandire zoopsa zamagetsi.Chitetezo cha RCD chimapulumutsa moyo komanso chimateteza ku moto.Mukakhudza waya wopanda kanthu kapena zinthu zina zapagulu la ogula, zimalepheretsa wogwiritsa ntchitoyo kuti asavulazidwe.Ngati choyikira chidula chingwe, zida zotsalira zimazimitsa mphamvu yomwe ikuyenda padziko lapansi.RCD ingagwiritsidwe ntchito ngati chipangizo chomwe chikubwera chomwe chimadyetsa magetsi kumagetsi.Pakachitika magetsi, RCD imatuluka ndikuchotsa zoperekera kwa ophwanya madera.

Chipangizo chotsalira chamakono kapena chodziwika bwino kuti RCD ndi chida chofunikira kwambiri pachitetezo chamagetsi.RCD imagwiritsidwa ntchito makamaka kuteteza munthu ku mantha amagetsi owopsa.Ngati pali vuto ndi chipangizo m'nyumba, RCD imachita chifukwa cha kukwera kwa mphamvu ndikuchotsa magetsi.RCD idapangidwa kuti iyankhe mwachangu.Chipangizo chamakono chotsalira chimayang'anira mphamvu yamagetsi ndi nthawi yomweyo ya zochitika zosazolowereka zomwe chipangizochi chimachita mofulumira.

Ma RCD amapezeka m'njira zosiyanasiyana ndipo amachita mosiyana kutengera kupezeka kwa zigawo za DC kapena ma frequency osiyanasiyana.Mulingo wachitetezo chomwe amapereka pamafunde amoyo ndiakulu kuposa fuse wamba kapena chowombera mlengalenga.Ma RCD otsatirawa amapezeka ndi zizindikilo zake ndipo wopanga kapena woyikira akuyenera kusankha chipangizo choyenera kugwiritsa ntchito.

Type S (Nthawi Yachedwa)

A Type S RCD ndi chipangizo chotsalira cha sinusoidal chomwe chimaphatikizapo kuchedwa kwa nthawi.Itha kukhazikitsidwa kumtunda kuchokera ku Type AC RCD kuti ipereke kusankha.RCD yochedwa nthawi siyingagwiritsidwe ntchito powonjezera chitetezo chifukwa sichigwira ntchito mkati mwa nthawi yofunikira ya 40 mS.

Mtundu AC

Mitundu ya AC RCDs (General Type), yomwe nthawi zambiri imayikidwa m'nyumba, idapangidwa kuti igwiritsidwe ntchito posinthana ndi sinusoidal residual current kuti iteteze zida zomwe zimalimbana ndi mphamvu, mphamvu kapena inductive komanso zopanda zida zilizonse zamagetsi.

General Type RCDs alibe kuchedwa kwa nthawi ndipo amagwira ntchito nthawi yomweyo pozindikira kusalinganika.

Mtundu A

Ma RCD a Type A amagwiritsidwa ntchito posinthana ndi sinusoidal residual current komanso potsalira pakali pano mpaka 6 mA.

Kodi ndimayesa bwanji Mitundu yosiyanasiyana ya RCD?
Palibe zofunikira zina kuti woyikirayo ayang'ane ngati akugwira ntchito moyenera pomwe akugwiritsa ntchito DC yotsalira.Kuyesa uku kumachitika panthawi yopanga ndipo kumatchedwa kuyesa kwamtundu, komwe sikuli kosiyana ndi momwe timadalira pakali pano ophwanya madera omwe ali ndi vuto.Mitundu ya A, B ndi F RCDs imayesedwa mofanana ndi AC RCD.Tsatanetsatane wa njira yoyeserera komanso nthawi yayitali yolumikizira imapezeka mu IET Guidance Note 3.
Nanga bwanji nditapeza mtundu wa AC RCD ndikuwunika zamagetsi panthawi yoyika lipoti lamagetsi?
Ngati woyang'anira akuda nkhawa kuti zotsalira za DC zomwe zatsalira zitha kukhudza magwiridwe antchito a Type AC RCDs, kasitomala ayenera kudziwitsidwa.Wofuna chithandizo ayenera kudziwitsidwa za zoopsa zomwe zingatheke komanso kuwunika kuchuluka kwa zotsalira zotsalira za DC ziyenera kupangidwa kuti adziwe ngati RCD ndi yoyenera kugwiritsidwa ntchito.Kutengera kuchuluka kwa zolakwika za DC zotsalira, RCD yomwe idachititsidwa khungu ndi zotsalira za DC zotsalira sizingagwire ntchito zomwe zitha kukhala zowopsa ngati kusakhala ndi RCD yoyikidwira poyamba.
Kudalirika kwapantchito kwa RCDs
Maphunziro ambiri okhudzana ndi kudalirika kwa ntchito achitika pa ma RCD omwe adayikidwa m'malo osiyanasiyana omwe amapereka chidziwitso pazovuta zomwe chilengedwe komanso zinthu zakunja zimatha kukhala nazo pakugwira ntchito kwa RCD.
