Chenjezo kwa ma leakage circuit breakers

Kuyika

1. Musanakhazikitse, fufuzani ngati deta pa nameplate ya kutayikirawowononga derazimagwirizana ndi zofunikira zogwiritsira ntchito.
2. Musati kukhazikitsa pafupi kwambiri basi mkulu-panopa ndi AC contactor.
3. Pamene mphamvu yogwiritsira ntchito magetsi oyendetsa magetsi ndi aakulu kuposa 15mA, chipolopolo cha zida zotetezedwa ndi icho chiyenera kukhala chokhazikika.
4. Njira yoperekera mphamvu, magetsi ndi mawonekedwe apansi a dongosolo ayenera kuganiziridwa bwino.
5. Mukayika chowotcha chowotcha ndi chitetezo chachifupi, payenera kukhala mtunda wokwanira wa arcing.
6. Dongosolo loyang'anira kugwirizana kwakunja kwa chophatikizira chophatikizira chophatikizira chotayirira chiyenera kugwiritsa ntchito waya wamkuwa wokhala ndi gawo laling'ono la osachepera 1.5mm².
7. Pambuyo poyendetsa dera lotayirira, njira zotetezera zoyambira zoyambira zoyambira zotsika kwambiri kapena zida sizingachotsedwe.Panthawi imodzimodziyo, mzere wosalowerera wa mbali ya katundu wa woyendetsa dera suyenera kugawidwa ndi maulendo ena kuti asagwire ntchito bwino.
8. Waya wosalowerera ndale ndi waya woteteza pansi ayenera kukhala wosiyana kwambiri panthawi ya kukhazikitsa.Waya wosalowerera ndale wa mawaya atatu-waya-waya anayi ndi-pole-pole leakage circuit breaker iyenera kulumikizidwa ndi chophwanya dera.Waya wosalowerera ndale womwe umadutsa pawotchinga wozungulira sungagwiritsidwenso ntchito ngati waya wotchingira pansi, komanso sungathe kukhazikitsidwa mobwerezabwereza kapena kulumikizidwa ndi mpanda wa zida zamagetsi.Waya woteteza pansi sayenera kulumikizidwa ndi chophwanyira chowotcha.
9. Mtundu wachitetezo cha chotchinga chowotchera uyenera kukhala chozungulira chodziyimira pawokha ndipo sungathe kulumikizidwa ndi magetsi kumayendedwe ena.Zowonongeka zowonongeka sizingagwiritsidwe ntchito mofanana kuteteza dera lomwelo kapena zipangizo zamagetsi.
10. Pambuyo pa kukhazikitsa, gwiritsani ntchito batani loyesa kuti muwone ngati chowotcha dera lotayirira lingathe kugwira ntchito modalirika.Nthawi zonse, iyenera kuyesedwa kupitilira katatu ndipo imatha kugwira ntchito bwino.

Wiring

1. Wiring ayenera kuchitidwa molingana ndi mphamvu zamagetsi ndi zizindikiro zonyamula katundu pa chowotcha dera lotayirira, ndipo ziwirizo siziyenera kusinthidwa.
2. Mzere wachitetezo suyenera kudutsa pa zero-sequence current transformer.Pamene dongosolo la magawo atatu lawaya kapena gawo limodzi la mawaya atatu likutengera, chingwe chachitetezo chiyenera kulumikizidwa ndi mzere wa thunthu lachitetezo kumapeto kwa chowotcha chowotcha, ndipo sayenera kudutsa ziro. panopa mutual inductance pakati.Chipangizo.
3. Pazigawo zounikira zagawo limodzi, magawo atatu a magawo anayi ogawa mawaya ndi mizere ina kapena zipangizo zomwe zimagwiritsa ntchito mzere wosalowerera ndale, mzere wosalowerera uyenera kudutsa pa zero-sequence current transformer.
4. Mu dongosolo lomwe gawo losalowerera ndale la transformer limakhazikitsidwa mwachindunji, pamene chowotcha dera lotayirira chikayikidwa, mzere wosalowerera womwe umagwira ntchito ukhoza kugwiritsidwa ntchito ngati mzere wosalowerera ndale pambuyo podutsa zero sequence current transformer.Mawaya osalowerera omwe amagwira ntchito a mizere ina amalumikizidwa.
5. Zipangizo zamagetsi zimatha kulumikizidwa kokha ku mbali yonyamula katundu wa dera lotayirira.Mapeto amodzi saloledwa kuti agwirizane ndi mbali yonyamula katundu ndi mapeto ena kumbali ya magetsi.
6. Muzitsulo zitatu zazitsulo zinayi kapena katatu kagawo kakang'ono kakang'ono kamene kamakhala kosakanikirana ndi magawo atatu, yesetsani kugwirizanitsa magawo atatu.

Mbiri Yakampani

Malingaliro a kampani Changan Group Co., Ltd.ndi wopanga mphamvu ndi kutumiza kunja kwazipangizo zamagetsi zamagetsi.Tadzipereka kukonza moyo wabwino komanso chilengedwe kudzera mu gulu la akatswiri a R&D, kasamalidwe kapamwamba komanso ntchito zogwira mtima.
