Kodi njira zisanu zotetezera magetsi za ma switchgear okwera kwambiri ndi ziti?

Lingaliro la kupewa zisanu:

1. Anti-katundu kutsegula ndi kutseka cholumikizira;

2. Pewani kutsegulidwa kwabodza ndi kutseka kwa ophwanya dera;

3. Anti-katundu kutseka grounding lophimba;

4. Katundu kufala pamene odana grounding lophimba chatsekedwa;

5. Pewani kulowa m'malo molakwika.

Chotsekera kasanu ndi loko yoyikidwa kuti ikwaniritse njira zisanu zopewera zomwe zili pamwambapa.Kuti akwaniritse ntchito yeniyeni ya kupewa zisanu, iyeneranso kugwirizana ndi microcomputer kachitidwe kasanu kapewedwe kapena kudzera mwa ogwira ntchito okhwima malamulo asanu oletsa ntchito.

"Njira zisanu zodzitetezera pamagetsi" za ma switchgear okwera kwambiri:

"Interlocking" ya high-voltage switchgear ndi njira yofunikira yowonetsetsa kuti gridi yamagetsi ikugwira ntchito bwino, kuonetsetsa chitetezo cha zida ndi ogwira ntchito, ndikupewa kusokoneza.GB3906-1991 "3 ~ 35 kV AC Metal-enclosed Switchgear" yapereka makonzedwe omveka bwino pa izi.Kawirikawiri, "kulowetsedwa" kumatanthauzidwa kuti: kuteteza kutsekula konyenga ndi kutseka kwa wodutsa dera;kuteteza kutsegula ndi kutseka kwa disconnector ndi katundu;kuletsa kupachikidwa (kutseka) kwa waya wapansi (chosinthira) ndi mphamvu;kuteteza kutseka kwa waya pansi (kusintha) ndi mphamvu;kuletsa kulowa malo okhala molakwika.Zomwe zili pamwambazi zoletsa kusokoneza magetsi zimatchedwa "zoletsa zisanu"."Zisanu zopewera" Zida nthawi zambiri zimagawidwa m'makina, magetsi ndi magulu athunthu.Pakadali pano, pali mitundu yambiri yama switchgear okwera kwambiri pamsika, ambiri omwe ali ndi njira yolumikizira shaft yabwino.

1. Pambuyo pa trolley ya vacuum circuit breaker mu high-voltage switch cabinet imatsekedwa pa malo oyesera, woyendetsa dera la trolley sangathe kulowa ntchito.(Letsani kutseka ndi katundu).

2. Pamene chosinthira pansi mu kabati ya high-voltage switch chatsekedwa, trolley circuit breaker sangathe kutsekedwa.(Letsani kutseka ndi waya woyika pansi).

3. Pamene chotchinga chamagetsi mumagetsi othamanga kwambiri chatsekedwa, chitseko chakumbuyo cha gulu ndi kabati chimatsekedwa ndi chitseko cha kabati ndi makina opangira mpeni.(Letsani kulowa malo okhalamo molakwika).

4. Chowotcha chopukutira mu kabati yamagetsi okwera kwambiri chimatsekedwa panthawi yogwira ntchito, ndipo chotchinga chotsekera sichingagwire ntchito.(Letsani kupachika kwa waya pansi).

5. Wowononga dera la vacuum mu kabati yamagetsi apamwamba sangathe kuchoka pamalo ogwirira ntchito a trolley circuit breaker pamene yatsekedwa.
