CNHWX-12 BIRTA LA SAMEEYEY EE QAFSKA XIRAN
Waxqabadka shay ee sanduuqa qafiska giraanta isku dhafka ah ee aasaasiga ah iyo sare kama hooseeyo S304 birta aan lahayn ama walxaha GRC (fiber-glass xoojiyey sibidhka) iyo agabyada kale. Qolfoofku waa inuu lahaadaa awood farsamo oo ku filan, waana in aan la beddelin ama aanu dhaawacmin inta lagu jiro qaadista, gaadiidka iyo rakibidda. Heerka ilaalinta ee sanduuqa dibadda waa inuusan ka hooseynin IP43. Haddii shayga qafiska giraantu uu yahay bir, dhumucda magacu waa ≥ 2mm, weecan cabbirka la ogolyahayna waxa uu buuxinayaa shuruudaha saxda ah ee Heerka B ee "Gb/T 708 Cabirrada, Qaababka, Miisaanka iyo weecashooyinka la ogol yahay ee Birta Qabow-duuban iyo Birta Dharbaaxo".
Sanduuqa dibadda ee birta ah waa in lagu daaweeyaa tignoolajiyada daahan ka-hortagga daxalka. Dahaarku waa inuu noqdaa mid isku mid ah oo dhumucdiisuna ay joogto tahay. Dahaarka waa inuu lahaadaa adhesion xooggan.
Dulmar
Horumarka iyo horumarka joogtada ah ee bulshada, dalkeeyga koronto ee magaalooyinka waxaa ku dhacay isbedel aad u weyn. Magaalooyinka badankoodu waxay samaysteen ama samaynayaan meelo badan oo koronto badan leh. Waagii hore, korontada ka imanaysa 12/24kV khadadka hoose [ama xadadka laanta] si ay u toosiyaan isticmaalayaasha waxay awoodi waayeen inay buuxiyaan shuruudaha horumarinta magaalooyinka. Natiijo ahaan, hab cusub oo koronto ayaa soo baxay si uu koronta ugu siiyo isticmaaleyaasha iyada oo loo marayo furayaasha. Si kastaba ha ahaatee, iyadoo la xoojinayo cufnaanta magaalooyinka, qaar ka mid ah beddelka madaniga ah ee asalka ah ayaa lagu xaddiday dhulka iyo qorsheynta magaalada. Sidaa darteed, sanduuqa giraanta sare ee korantada sare ee dibadda ayaa soo baxay. Alaabtani uma baahna dhismo madani ah waxayna qabsataa aag yar. Qaabeynta ayaa ah mid aad u jilicsan oo habka korontadu waa mid la isku halleyn karo. Waqtiga dhismaha, rakibidda iyo wax-ka-hortagga ayaa si weyn loo soo gaabiyay, qiimaha guudna waa la dhimay.
Iyada oo horumarinta warshadaha casriga ah, heerka otomaatiga iyo sirdoonka qalabka kontoroolka korantada ayaa sii kordhaya oo sarreeya. Farsamada elektiroonigga ah ee casriga ah, tignoolajiyada dareemayaasha, tignoolajiyada isgaarsiinta, iyo tignoolajiyada shabakada kombuyuutarka ayaa loo isticmaalaa si loola socdo, loo ilaaliyo, loona kormeero qalabka korontada ee xaaladaha caadiga ah iyo shilalka. Isku dhafka xakamaynta iyo cabbirka si loo gaaro maamul wanaagsan ayaa noqday isbeddel lama huraan ah iyo jihada horumarineed.
Sanduuqa giraanta korantada sare ee dibadda (standardized) wuxuu qaataa oo wax ka bartaa tikniyoolajiyada horumarsan ee ajnabiga ah, isku dhafka 12/24kV golaha beddelka, jebinta wareegga, beddelka culeyska, beddelka korantada ee 12/24kv PT, xarunta beddelka FTU, RTU, isgaarsiinta Xakamaynta Terminalka (CCu). Qiyaasta 12/24kV iyo mitirka otomaatiga ah, sahayda tamarta USP iyo qalabyada tilmaamaya ayaa lagu rakibay oo laga saarayaa sanduuqa birta ah ee la saari karo, shaabadaysan iyo qoyaanka aan caddayn, taas oo ogaanaysa nidaamka aasaasiga ah iyo sare ee shabakada qaybinta magaalooyinka. Isku-dhafka iyo isku-dhafka moodeelka ah waxay soo gaabinayaan wareegga dhismaha waxayna si weyn u wanaajiyaan isku halaynta shaqada koronto ee magaalooyinka.
Tilmaamaha ugu muhiimsan ee alaabta
Alaabtu waxay qabataa dahaarka gaaska waxaana lagu qalabayn karaa xalalka aasaasiga ah sida jebiyaasha wareegga, furayaasha xamuulka, iyo qalabka korantada ee la isku daray. Alaabtani waa naqshad isdhexgalka aasaasiga ah iyo kan sare ee ku salaysan heerarka otomaatiga ah ee shabakada qaybinta ee ugu dambeeyay, isku dhafka DTU, dareenka garaadka, ogaanshaha internetka iyo qaybaha kale ee caqliga leh, waxayna ku habboon tahay codsiyada nidaamka otomaatiga ah ee shabakada qaybinta kala duwan.
