Shenhai Explosion-Proof
Raws li cov txheej txheem teeb tsa los ntawm cov qauv kev teeb tsa rau cov khoom siv hluav taws xob tawg, zoo li GB3836.15, cov khoom siv hluav taws xob zoo li no tuaj yeem siv TN, TT, thiab IT systems. Cov txheej txheem no yuav tsum ua raws li tag nrho cov qauv hauv lub tebchaws, suav nrog cov kev xav tau tshwj xeeb ntxiv cov khoom siv hluav taws xob tau piav qhia hauv GB3836.15 thiab GB12476.2, nrog rau kev siv cov kev tiv thaiv tsim nyog.
Siv lub zog TN, piv txwv, tshwj xeeb tshaj yog TN-S variant, uas muaj qhov sib txawv nruab nrab (N) thiab tiv thaiv (PE) tus thawj coj. Nyob rau hauv ib puag ncig txaus ntshai, cov conductors no yuav tsum tsis txhob muab merged los yog txuas ua ke. Thaum muaj kev hloov pauv ntawm TN-C rau TN-S hom, tus neeg xyuas pib tiv thaiv yuav tsum tau txuas nrog equipotential bonding system nyob rau hauv qhov chaw tsis muaj kev phom sij. Tsis tas li ntawd, nyob rau thaj chaw muaj kev phom sij, Kev saib xyuas zoo ntawm cov kab nruab nrab thiab PE tiv thaiv tus neeg xyuas pib yog qhov tseem ceeb.
