Main earthing dongosolo

Munthu amene adziwa pang'ono za ukachenjede magetsi, zingaoneke kuti nyumba zonse zogona ntchito chimodzimodzi mphamvu yogawa ziwembu: omwewo awiri mawaya, masiwichi ndi zitsulo.
Komabe, zambiri zovuta ndi chakuti malingaliro - basi "nsonga ya madzi oundana lapansi." Alipo madera mphamvu yogawa ndi osiyana wina ndi mzake, poyamba pa zonse, njira grounding ndi ikuyambitsa zomera ndi zida kumbali ogula. M'mawu ena, iwo ndi machitidwe osiyana earthing. Ngakhale kuti si zoonekeratu mfundo imeneyi n'kofunika kwambiri.

Pakali pano, ankagwiritsa ntchito atatu grounding dongosolo zofunika - mitundu IT, TN, TT, ndi ena ofanana zace. chizindikiro ichi ndi nkhani ndithu, koma choncho, ngati inu mukudziwa momwe decrypt izo.

Alipo dongosolo pansi

tanthauzo limeneli amatanthauza munthu kapena kasinthidwe zina za gululi alipo, amaganizira chimake ntchito ya grounding mapeto zida wosuta ali nawo monga waya pansi ndi mzere ziro, komanso ngati ndale ndi otsendereka. Ndiko kuti, lingaliro ili ndi ambulera. Malinga kuphatikiza zinthu izi, pali magulu atatu.

Mmodzi wa chachikulu - TN izi. Ndi chidule cha Terre Neutre, omwe angathe kumasuliridwa ku French monga earthed ndale.

Ndi zomveka chitukuko cha TN-C. Pano, "C" umaimira "Pamodzi". Mosiyana yoyamba kuti waya ndale grounding amaphatikizidwa mu mzere umodzi. Mbali imeneyi zimathandiza inu kuchepetsa chiwerengero cha mizere anaika, koma vuto la kum'dula pakamwa wa waya milandu m'gulu zipangizo zopezera limapezeka angathe magetsi, zomwe ndi zoopsa. Komabe, nthawi zina njira yotero ntchito, pakalibe aluso mu lathyathyathya lachitatu waya pansi: m'malo mwake pakati pa ziro ndi earthing kukhudzana jumper aikidwa. Chotero dongosolo grounding tikulimbikitsidwa kuti ntchito milandu iwiri:

- palibe njira ina zida nthaka;

- mzere uli Komanso kutetezedwa chipangizo tripping RCDs.

Amasiyana kotheratu kuphatikiza - ndi TN-S (kuchokera «osiyana» - kugawanika). Iwo ziro ndi dziko lapansi mizere osiyana.

Kenako dongosolo lalikulu - ndi TT. Amapanga akuimira awiri grounding mizere palokha: chimodzi ayipanga pa mbali thiransifoma, ndipo chachiwiri - ogula.

Potsiriza, mmodzi wa mungachite yodalirika anafotokoza dongosolo limene mizere ndale akutali anapanga, ndipo thupi zonse za magetsi ogula adzatsekeredwa chinakhazikika. Chifukwa cha zachilengedwe kutayikira panopa ndi zonyozeka kwambiri, ndipo ngakhale inu mwangozi anagunda munthu pansi zochita za magetsi angathe ngozi si adasiya pansi. Pankhaniyi n'kofunika kulamulira mtengo kukana.

Pakuti dongosolo lililonse chakuti akuoneni ulamuliro kuti earthing kukana mwina upambana 4 ohms. Choncho, dongosolo lililonse, ku chikhomo grounding ndi mawaya kutsirizitsa ndi mfundo mogwirizana, izo zili zoletsedwa ndi lamulo limeneli.
