Isku xidhka siman ee hababka sawir-qaadista Aaladaha dhulka dhigaya iyo kirishbooyada ilaalinta ee nidaamyada sawir-qaadista waa inay u hoggaansamaan IEC60364-7-712:2017, taasoo bixisa macluumaad dheeraad ah. Meesha ugu yar ee iskutallaabtu waa inay buuxisaa shuruudaha IEC60364-5-54, IEC61643-12 iyo GB/T21714.3-2015. Haddii xariijimaha isku dhejinta siman loo isticmaalo sida kirishbooyada, aaggooda ugu yar ee iskutallaabtu waa inay ahaadaan fiilooyin naxaas ah oo ah 50mm, ama kirishbooyada awooda hadda qaadaya oo u dhigma. Haddii xariijinta isku dheelitirka siman ee la filayo inay qabato hillaaca hadda jira, aagga ugu yar ee iskutallaabtu waa inuu noqdaa 16mm silig biin ah, ama awood u dhiganta hadda. kirishbooy. If the equipotential bonding strip is expected to conduct only induced lightning current, its minimum cross-sectional area shall be 6mm copper wire or equivalent current-carrying capacity kirishbooy. Meesha ugu yar ee isku-tallaabta ah ee kirishbooyada isku xira ee ku xiraya qaybaha korantada ee xariijinta isku dheelitirka waa inay noqotaa 6mm silig naxaas ah, ama awood u dhigma hadda kirishbooy. Maqnaanshaha nidaamka sawir-qaadista ee ku xiran nidaamka ilaalinta hillaaca, meesha ugu yar ee isku-tallaabta ah ee isku-xireyaasha isku xira ee ku xiran xargaha isku xirka ee kala duwan iyo kirishtaannada ku xiran nidaamka dhulka waa inay ahaadaan 6mm silig naxaas ah, ama hadda u dhigma - qaadiyaasha awoodda qaada. Fiiro gaar ah: Shuruudaha ugu yar ee qaybta isdhaafka ee kirishbooyada ayaa ku kala duwan wadamada qaarkood. Kala duwanaanshahan waxaa lagu sharaxay GB/T 217143-2015. Qaybta LPS ee la filayo inay ku socoto qayb ka mid ah hillaaca hadda waa inay u hoggaansamaan IEC 62561 (dhammaan qaybaha). Marka nidaamka sawir-qaadista lagu ilaaliyo nidaamka ilaalinta hillaaca, fogaanta ugu yar ee badbaadada leh waa in la ilaaliyaa inta u dhaxaysa nidaamka ilaalinta hillaaca iyo qaababka birta ee nidaamka sawir-qaadista si looga hortago qayb ka mid ah iftiinka iftiinka ee ku qulqulaya dhismayaashan. Meesha ugu yar ee isku-tallaabta ah ee dhammaan kondhomiyeyaasha isku-xidhka isku-dhafan waa 6mm, marka laga reebo kormeerayaasha dhulka ee fasalka 1-aad ee ilaalinta ee golaha qaybinta ugu weyn. Haddii qaybaha sawir-qaadista ay ilaalinayaan nidaamka ilaalinta hillaaca laakiin fogaanta kala-soocidda badbaadada ah lama sii wadi karo inta u dhaxaysa labada, xiriir toos ah waa in lagu daraa inta u dhaxaysa nidaamka ilaalinta iftiinka dibadda iyo qaabka birta ah ee sawirka sawirka. Xidhiidhkani waa inuu awood u yeeshaa inuu u adkaysto qaar ka mid ah hadda hillaaca. Meesha ugu yar ee isdhaafsiga ah ee kormeeraha isku xidhka siman waa inuu buuxiyaa shuruudaha IEC60364-5-541EC61643-12 iyo GB/T217143-2015. Meesha ugu yar ee iskutallaabta ah ee dhammaan daalacayaasha isku xidhka siman waa inay ahaadaan 16mm, marka laga reebo xargaha isku xidhka siman ee loogu talagalay in lagu dejiyo beddelka.
