Lowani mu labotale yathu, lowetsani mkati mwa magetsi athu, dziwani zambiri, chidwi chambiri, chokonda kwambiri, Izi ndizomwe kuyika chizindikiro kumatanthawuza, chithumwa cha mtundu.
Kuyesa ngati kukana kwapansi kumakwaniritsa zofunikira za muyezo ndikulonjeza chitetezo cha magetsi kwa anthu.
Ntchito ya grounding ndi kuti pamene kutchinjiriza kwa magetsi kulephera, kutayikira panopa adzakhala mwachindunji amapita ku dziko lapansi kudzera pansi waya ndipo sadzapweteka thupi la munthu. Choncho, ang'onoang'ono grounding kukana, otetezeka kwambiri.
Momwe mungayesere kukana kwapansi?
Timayesa pansi pa Europe standard:12A yamakono, nthawi yoyesera masekondi 5, ngati kukana kwapansi ≦ 500m, ndikoyenerera.
Tiyeni ntchito wofiira kopanira kulumikiza grounding waya.
chojambula chakuda chimagwirizanitsa thupi la kuwala komwe kumapeza magetsi mosavuta, nthawi zambiri timasankha screw.
Kenako yambani kuyesa.
Tsopano, tiyeni tiyang'ane kukana kwapansi 23MΩ, zotetezeka kwathunthu.
Pali mfundo zitatu zofunika kukana:
1. Zida za waya wakunja, waya wamkuwa, womwe uli ndi ma conductivity amphamvu komanso kukana kochepa
2. Gawo lalikulu la waya, lalikulu, kukana kochepa, malinga ndi muyezo wa IEC, gawo la waya likufunika ≥ 0,75 millimeters.,timakwaniritsa zofunikira komanso zapamwamba kuposa msika.
3. Chip board, pali gawo lomwe limalumikiza waya pansi, liyenera kumangitsa wononga, kapena lidzataya mphamvu.
Zikomo powerenga nkhaniyi, ndife liper, ndife opanga kuwala kwa LED, sitimangopanga dziko kupulumutsa mphamvu zambiri, komanso khalani otetezeka.
Tikuwonani nthawi ina.
