1P+N, RCBO, B, C curve, ETM8RF, Residual Current Breaker yokhala ndi chitetezo chokwanira, din njanji
Kufotokozera Zamalonda
ETM8RF mndandanda wa RCBO umagwira ntchito pagawo lamagetsi otsika kwambiri pamsika, zomanga za anthu monga nyumba ndi nyumba, mphamvu, kulumikizana, zomangamanga, njira yogawa zowunikira kapena kugawa magalimoto ndi magawo ena.Amapereka chitetezo chotuluka, chitetezo chachifupi, chitetezo chochulukirapo, komanso chitetezo chodzipatula, chomwe chingateteze munthu kuti asavulaze chifukwa cha kutayikira kwapano, makamaka pomwe amatha kuteteza dera ndi zida ku ngozi yachiwiri yomwe imachitika chifukwa chakuchulukirachulukira komanso kufupika. dera.
ETM8RF mndandanda RCBO ikugwirizana ndi IEC 61009-1standard.
Kuphwanya mphamvu ya ETM8RF ndi 10KA, kapena 6KA
Mtundu wodutsa wafupipafupi ndi B, C curve.
Zomwe zidavoteledwa ndi 6A, 10A, 16A, 20A, 25A, 32A, 40A.Zomwe zidavotera zimagwirizana ndi malo osiyanasiyana pogwiritsa ntchito mwachitsanzo, pole 10 mpaka 16 ampere nthawi zambiri imagwiritsidwa ntchito powunikira, 20 ampere mpaka 33 ampere nthawi zambiri imagwiritsidwa ntchito kukhitchini ndi bafa, imagwiritsidwanso ntchito ngati chowongolera mpweya ndi zida zina.
Mphamvu ya Residual Current, kapena Earth Leakage tripping ndi 10mA, 30mA, 100mA, pomwe 10mA ndi 30mA imagwiritsidwa ntchito makamaka pozungulira zipinda zosambira ndi khitchini kuteteza munthu kuti asagwedezeke ndi magetsi.
Mtundu wodutsa wa Residual current ndi AC kapena A class.Kuyenda kwa kalasi ya AC kumatsimikiziridwa ndi sinusoidal, mafunde osinthasintha, kaya agwiritsidwe ntchito mwachangu kapena akuwonjezeka pang'onopang'ono.Kuyenda kwa kalasi kumatsimikiziridwa ndi ma sinusoidal, mafunde osinthika otsalira komanso mafunde otsalira a DC, kaya ayikidwa mwachangu kapena akuwonjezeka pang'onopang'ono.
Mphamvu yamagetsi: 230V / 240V (Gawo & Ndale)
Pali chizindikiro cha udindo chomwe chili pazogulitsa, Red yayatsidwa, Green yazimitsa.
Ma terminals a RCBO ndi chitetezo cha IP20 chomwe chimapangidwira kuti chala ndi chala chigwire bwino kuti chitetezeke pakukhazikitsa.
ETM8RF RCBO imatha kugwira ntchito modalirika m'malo ovuta, kutentha kozungulira kuyambira -25°C mpaka 55°C.
Moyo wamagetsi ukhoza kugwira ntchito mpaka 8000 ndi moyo wamakina mpaka 20000, pomwe chofunikira cha IEC ndi ntchito 4000 zokha ndi ntchito 10000.
Mtundu wake wokwera uyenera kukwera pa din njanji EN60715 35mm.
RCBO ndi chiyani?
RCBO imayimira Residual Current Breaker yokhala ndi chitetezo cha Over-Current.RCBO imaphatikiza magwiridwe antchito a MCB ndi RCD/RCCB.Pakakhala kutayikira kwakanthawi, RCBO imayendetsa dera lonse.Chifukwa chake, zida zamkati zamaginito / zotenthetsera zimayendetsa chipangizo chamagetsi pomwe dera ladzaza.
1. Residual Current, kapena Earth Leakage - Zimachitika pakaduka mwangozi kuzungulira kudzera pa waya wopanda magetsi kapena ngozi za DIY monga kuboola chingwe pokweza mbedza ya chithunzi kapena kudula chingwe ndi chotchera udzu.Pamenepa magetsi amayenera kupita kwinakwake ndikusankha njira yosavuta yodutsa pa chotchera udzu kapena kubowola kupita kwa munthu kuchititsa kugwedezeka kwamagetsi.
2. Over-Curent imatenga mitundu iwiri:
a.Kuchulukirachulukira - Kumachitika pamene zida zambiri zimagwiritsidwa ntchito pozungulira, kujambula kuchuluka kwa mphamvu zomwe zimaposa mphamvu ya chingwe.
b.Dera Lalifupi - Zimachitika ngati pali kulumikizana kwachindunji pakati pa okonda amoyo komanso osalowerera ndale.Popanda kukana komwe kumaperekedwa ndi mayendedwe abwinobwino, magetsi amayenda mozungulira mozungulira ndikuchulukitsa amperage ndi masauzande ambiri m'ma milliseconds ndipo ndiwowopsa kwambiri kuposa Overload.
Pomwe RCCB idapangidwa kuti iteteze ku kutayikira kwapadziko lapansi ndipo MCB imateteza kokha kuzomwe zikuchitika, RCBO imateteza ku mitundu yonse ya zolakwika.
M'moyo weniweni, zida zamagetsi monga zotsalira zamagetsi zamagetsi (zomwe zimadziwika kuti leakage switch) zimagwiritsidwa ntchito pafupifupi malo aliwonse okhala ndi magetsi.Amagwiritsidwa ntchito makamaka kuti azindikire zotsalira zapano, kuyerekezera mtengo wotsalira wamakono ndi mtengo wamtengo wapatali, ndikuchotsa kukhudzana kwakukulu kwa dera pamene mtengo wotsalira umaposa mtengo wotchulidwa.Pamene kugwedezeka kwamagetsi kwamunthu kapena kutayikira kwa gridi kupitilira mtengo womwe watchulidwa, chotsalira chamagetsi chotsalira chimatha kuletsa magetsi olakwika munthawi yochepa kwambiri, kuteteza chitetezo cha zida zamunthu ndi zamagetsi, komanso kuteteza chitetezo chamagetsi. Kuchulukira kapena kufupika kwa mzere ndi mota, komanso Itha kugwiritsidwa ntchito posintha mizere pafupipafupi komanso kusayambika kwa ma mota, ndipo imagwiritsidwa ntchito kwambiri pamagetsi pakupanga ndi moyo.
1. Kuthamangitsidwa kwa chitetezo chodzidzimutsa kumatanthawuza chipangizo chotetezera kutayikira chomwe chili ndi ntchito yofufuza ndi kuweruza kutayikira panopa, koma alibe ntchito yodula ndi kulumikiza dera lalikulu.Chitsimikizo choteteza kutayikira chimapangidwa ndi thiransifoma yotsatizana zero, kumasula ndi kulumikizana kothandizira kuti chizituluka.Ikhoza kugwirizana ndi kusintha kwachangu kwamakono monga chitetezo chamagetsi otsika-voltage magetsi kapena kutayikira, pansi kapena chitetezo chowunikira pamsewu waukulu.Pamene pali kutayikira panopa mu dera lalikulu, popeza kukhudzana wothandiza ndi kulekana amasulidwe lophimba waukulu dera olumikizidwa mu mndandanda kupanga dera, kukhudzana wothandiza chikugwirizana ndi kulekana kumasulidwa ndi disconnects lophimba mpweya, AC contactor, etc. lupu.Othandizira othandizira amathanso kulumikizidwa ku zida zamawu ndi zowunikira kuti atulutse chizindikiro cha alamu chotuluka kuti chiwonetse momwe mzerewo ulili.2. Chophimba choteteza kutayikira chimatanthawuza kuti sichingangotsegula kapena kuzimitsa dera lalikulu monga ophwanya madera ena, komanso ali ndi ntchito yozindikira ndikuweruza kutayikira kwapano.Pamene kutayikira kapena kuwonongeka kwa insulation kumachitika m'dera lalikulu, chosinthira choteteza kutayikira chikhoza kukhazikitsidwa ndi chinthu chosinthira chomwe chimatembenuza dera lalikulu kapena kuzimitsa chifukwa cha chigamulo.Imagwirizana ndi ma fuse ndi ma relay otenthetsera kuti apange mawonekedwe osinthira otsika kwambiri.
