Dongosolo Lopereka Mphamvu Yodzipatula Yachipatala
Kugwiritsa ntchito
Tanthauzo la dongosolo lamagetsi la IT lachipatala
Yankho la kusungira mphamvu kogwirizana ndi PV DC
Kalata yoyamba imasonyeza momwe malo osalowererapo ndi nthaka ya magetsi zilili:
T - imasonyeza kuti waya wosalowerera wa magetsi uli pansi mwachindunji;
I - imasonyeza kuti waya wosalowerera wa magetsi suli pansi kapena pansi ndi impedance yayikulu;
Kalata yachiwiri imasonyeza momwe mbali ya katundu ndi nthaka zilili;
T - Gawo loyendetsa magetsi lomwe limatuluka lili pansi mwachindunji, ndipo malo oyambira sali pansi pa malo oyambira a malo operekera magetsi;
N - Gawo loyendetsa magetsi lomwe lawonekera pa chipangizo chamagetsi limalumikizidwa mwachindunji ndi malo oyambira a malo operekera magetsi;
Chilembo chachitatu C chimasonyeza kuti mzere wosalowerera (mzere wa N) umagawidwa ndi mzere woteteza wa zero (mzere wa PE); chilembo chachinayi S chimasonyeza kuti mzere wosalowerera (mzere wa N) umalekanitsidwa ndi mzere wa PE.
N’chifukwa chiyani pakufunika njira ya IT kuchipatala?
Dongosolo la TN-S: chitetezo cha magetsi chosakwanira komanso kupitirizabe
1. Mu dongosolo lokhazikitsa nthaka, pamene vuto la waya wamoyo lachitika, waya wosalowerera umafupikitsidwa kupita pansi, chotseka magetsi chimagwa, ndipo kupitiriza kwa magetsi kumakhudzidwa.
2. Zipangizo zamagetsi zilizonse zoyendetsedwa ndi makina a TN zimatulutsa kutuluka kwa madzi pang'ono, zomwe zimawopseza ogwira ntchito zachipatala ndi odwala.
3. Ngati mphamvu yotuluka ya chipangizocho yapitirira mphamvu yogwira ntchito ya chotseka magetsi choteteza mphamvu yotuluka, chotseka magetsi chidzagwa, zomwe zimakhudzanso kupitiriza kwa magetsi.
Dongosolo la IT: chitetezo chabwino cha magetsi komanso kupitiriza
1. Dongosolo la IT silinakhazikitsidwe. Pamene waya wamoyo uliwonse wakhazikika (cholakwika choyamba cha nthaka), chipangizo chowunikira kutentha chimanena za vuto la nthaka, koma chotsegula magetsi sichingagwe, ndipo dongosololi likhoza kupitiriza kugwira ntchito ndi vutolo.
2. Chifukwa chakuti dongosolo silinakhazikike, mphamvu yotulutsira madzi imapanga kuzungulira kudzera mu mphamvu yogawa ya dongosolo. Pansi pa mphamvu yochuluka ya mphamvu, mphamvu yotulutsira madzi idzakhala yochepa, ndipo mphamvu yotulutsira madzi ya dongosolo imakhala pansi pa ma microampere.
3. Pa makina azachipatala a IT, miyezo ya IEC imafuna kuti zolowetsa ndi zotulutsa ma circuit breakers a makina a IT zisagwire ntchito yoteteza kupitirira muyeso ndipo zisazimangidwe zikapitirira muyeso.
