JCRD2-125 RCD: Kuteteza Miyoyo ndi Katundu Ndi Chitetezo Chamagetsi

M'nthawi yomwe magetsi akhala gawo lofunika kwambiri pa moyo wathu watsiku ndi tsiku, kufunikira kwa chitetezo chamagetsi sikungapitirire. Pogwiritsa ntchito kuwonjezereka kwa zipangizo zamagetsi ndi machitidwe m'malo okhala ndi malonda, chiopsezo cha zoopsa zamagetsi chimakweranso. Pofuna kuchepetsa zoopsazi, opanga apanga zida zapamwamba zotetezera magetsi, chimodzi mwazo ndiChithunzi cha JCRD2-125(Residual Current Circuit Breaker) - chipangizo chopulumutsa moyo chomwe chimapangidwa kuti chiteteze ogwiritsa ntchito ndi katundu kuti asagwedezeke ndi magetsi ndi moto womwe ukhoza kuchitika.

Kumvetsetsa JCRD2-125 RCD

JCRD2-125 RCD ndi chophwanya tcheru chamakono chomwe chimagwira ntchito pa mfundo yotsalira yotsalira. Amapangidwa makamaka kuti aziyang'anira dera lamagetsi chifukwa cha kusalinganika kulikonse kapena kusokonezeka kwa njira yamakono. Pakachitika kusalinganika komwe kwapezeka, monga kutayikira kwapano mpaka pansi, RCD imaphwanya mwachangu dera kuti iteteze kuvulaza anthu komanso kuwonongeka kwa katundu.

Chipangizochi chimapezeka m'mitundu iwiri: Mtundu AC ndi Mtundu A RCCB (Residual Current Circuit Breaker with Integral Overcurrent Protection). Mitundu yonseyi idapangidwa kuti iteteze ku kugwedezeka kwamagetsi ndi zoopsa zamoto koma zimasiyana pakuyankhira kwawo kumitundu ina yapano.

Lembani AC RCD

Mitundu ya AC RCDs ndiyomwe imayikidwa kwambiri mnyumba. Amapangidwa kuti ateteze zida zomwe zimalimbana ndi mphamvu, mphamvu, kapena inductive komanso zopanda zida zilizonse zamagetsi. Ma RCD awa alibe kuchedwa kwa nthawi ndipo amagwira ntchito nthawi yomweyo atazindikira kusalinganika kwa sinusoidal residual current.

Lembani A RCD

Mtundu A RCDs, kumbali ina, amatha kuzindikira zonse zotsalira za sinusoidal zotsalira komanso zotsalira zomwe zikugwedezeka mwachindunji mpaka 6 mA. Izi zimawapangitsa kukhala oyenera kugwiritsa ntchito pomwe zida zaposachedwa zitha kukhalapo, monga m'makina opangira mphamvu zongowonjezwdwa kapena malo opangira magalimoto amagetsi.

Zofunika Kwambiri ndi Ubwino

JCRD2-125 RCD ili ndi zinthu zingapo zochititsa chidwi zomwe zimapangitsa kuti ikhale yogwira mtima komanso yodalirika. Nazi zina mwazinthu zake zazikulu:

Mtundu wa Electromagnetic: RCD imagwiritsa ntchito mfundo yamagetsi kuti izindikire ndikuyankha mafunde otsalira, kuonetsetsa chitetezo chachangu komanso cholondola.

Chitetezo cha Kutuluka kwa Dziko:Poyang'anira kayendedwe kamakono, RCD imatha kuzindikira ndikuchotsa dera ngati dziko lapansi likutha, kuteteza kugwedezeka kwa magetsi ndi zoopsa zamoto.

Kuphwanya Mphamvu: Ndi mphamvu yosweka mpaka 6kA, JCRD2-125 imatha kuthana ndi mafunde amphamvu kwambiri, kupereka chitetezo champhamvu kumayendedwe afupiafupi komanso mochulukira.

Zovoteledwa Panopa Zosankha: Imapezeka m'mitundu yosiyanasiyana kuyambira 25A mpaka 100A (25A, 32A, 40A, 63A, 80A, 100A),RCDzitha kupangidwa kuti zigwirizane ndi machitidwe osiyanasiyana amagetsi ndi katundu.

Kumverera kwa Tripping: Chipangizochi chimapereka kukhudzika kwa 30mA, 100mA, ndi 300mA, kupereka chitetezo chowonjezera kukhudzana mwachindunji, kukhudzana kosalunjika, ndi zoopsa zamoto, motero.

Positive Status Indication Contact: Kulumikizana koyenera kumathandizira kutsimikizira momwe RCD ikuyendera.

35mm DIN Rail Mounting: The RCD akhoza wokwera pa muyezo 35mm DIN njanji, kupereka unsembe kusinthasintha ndi yosavuta kugwiritsa ntchito.

Kukhazikitsa kusinthasintha: Chipangizochi chimapereka mwayi wosankha kulumikizana kwa mzere kuchokera pamwamba kapena pansi, kutengera zomwe mumakonda komanso zofunikira.

Kutsata Miyezo: JCRD2-125 ikutsatira miyezo ya IEC 61008-1 ndi EN61008-1, kuwonetsetsa kuti ikukwaniritsa zofunikira zachitetezo ndi magwiridwe antchito padziko lonse lapansi.

Mafotokozedwe Aukadaulo ndi Magwiridwe

Kuphatikiza pazofunikira zake, JCRD2-125 RCD ili ndi ukadaulo wochititsa chidwi womwe umawonjezera kudalirika kwake komanso magwiridwe ake. Izi zikuphatikizapo:

• Adavotera Working Voltage: 110V, 230V, 240V ~ (1P + N), kupangitsa kuti ikhale yoyenera kugwiritsidwa ntchito pazinthu zosiyanasiyana zamagetsi.
• Insulation Voltage: 500V, kuwonetsetsa kuti ikugwira ntchito motetezeka ngakhale pansi pamikhalidwe yayikulu.
• Kuvoteledwa pafupipafupi: 50/60Hz, yogwirizana ndi ma frequency wamba amagetsi.
• Kuyesedwa kwa Impulse Kupirira Voltage (1.2/50): 6kV, kupereka chitetezo champhamvu ku ma voltage transients.
• Digiri ya Kuipitsa:2, yoyenera kugwiritsidwa ntchito m'malo okhala ndi kuipitsidwa kwapakati.
• Moyo Wamagetsi ndi Wamagetsi:Nthawi za 2,000 ndi nthawi za 2000, motero, kuonetsetsa kuti nthawi yayitali ndi yodalirika.
• Digiri ya Chitetezo: IP20, yopereka chitetezo choyambirira kukhudzana ndi ziwalo zowopsa.
• Ambient Kutentha: -5 ℃ ~ + 40 ℃ (ndi pafupifupi ≤35 ℃ tsiku lililonse), kulola kugwiritsidwa ntchito m'malo osiyanasiyana achilengedwe.
• Contact Position Indicator: Zobiriwira = ZOKHUDZA, Zofiira = ON, zomwe zimapereka chidziwitso chomveka bwino cha RCD.
• Mtundu Wolumikizana ndi Terminal: Busbar yamtundu wa chingwe/Pini, yokhala ndi mitundu yosiyanasiyana yolumikizira magetsi.

Kuyesa ndi Kudalirika Kwantchito

Kuwonetsetsa kudalirika kwa ma RCD ndikofunikira kuti azitha kuteteza ku zoopsa zamagetsi. Opanga amayesa mwamphamvu panthawi yopanga, yomwe imadziwika kuti kuyesa kwamtundu, kuti atsimikizire momwe chipangizocho chikuyendera pansi pamikhalidwe yosiyanasiyana. Ma RCD amtundu wa A, B, ndi F amayesedwa mofanana ndi AC RCD, ndi tsatanetsatane wa njira yoyesera komanso nthawi zodulirapo zomwe zafotokozedwa mumiyezo yamakampani monga IET Guidance Note 3.

Pakuwunika kwamagetsi, ngati woyang'anira apeza mtundu wa AC RCD ndipo akuda nkhawa ndi momwe DC yotsalira ingakhudzire ntchito yake, ayenera kudziwitsa kasitomala za zoopsa zomwe zingachitike ndikupangira kuti awone kuchuluka kwa DC yotsalira yapano. Kutengera kuchuluka kwa zotsalira zotsalira za DC, RCD yomwe imachititsidwa khungu ndi iyo imatha kulephera kugwira ntchito, ndikuyika chiwopsezo chachikulu chachitetezo.

Mapeto

Mwachidule, aChithunzi cha JCRD2-125ndi chida chofunikira kwambiri chachitetezo chamagetsi chomwe chimapereka chitetezo chokwanira pakugwedezeka kwamagetsi ndi zoopsa zamoto. Mawonekedwe ake apamwamba, kuphatikiza kuzindikira kwa ma elekitiroma, kutetezedwa kwa kutayikira kwa dziko lapansi, komanso kusweka kwakukulu, kumapangitsa kuti ikhale chisankho choyenera kugwiritsidwa ntchito m'malo okhala ndi malonda. Potsatira miyezo yapadziko lonse lapansi komanso njira zoyeserera mwamphamvu, JCRD2-125 RCD imapatsa ogwiritsa ntchito mtendere wamalingaliro komanso chitsimikizo chachitetezo chambiri. Pamene magetsi akupitiriza kugwira ntchito yofunika kwambiri pamoyo wathu watsiku ndi tsiku, kuyika ndalama pazida zamakono zotetezera magetsi monga JCRD2-125 RCD ndi chisankho chanzeru chomwe chingapulumutse miyoyo ndi kuteteza katundu ku zoopsa za magetsi.
