Isishwankathelo samanqaku aphambili oyilo lwezakhiwo zeemfumba zokutshaja isithuthi sombane

1. Iimfuno zobugcisa zokuhlawula iimfumba

Ngokwendlela yokutshaja,ev ukutshaja iimfumbazahlulwe zaba zintlobo ezintathu: iimfumba zokutshaja ze-AC,DC ukutshaja iimfumba, kunye ne-AC kunye ne-DC edibeneyo yokutshaja iimfumba.izikhululo zokutshaja ze-DCzifakwa ngokubanzi koohola bendlela, kwizikhululo zokutshaja nakwezinye iindawo;Izikhululo zokutshaja ze-ACzidla ngokufakelwa kwiindawo zokuhlala, iindawo zokupaka iimoto, iindawo zokupaka iindlela, iindawo zeenkonzo zikahola wendlela kunye nezinye iindawo. Ngokweemfuno zeState Grid Q/GDW 485-2010 standard, iimfumba yokutshaja imoto yombaneumzimba kufuneka uhlangabezane nezi meko zilandelayo zobugcisa.

Iimeko zokusingqongileyo:

(1) Ubushushu bendawo yokusebenza: -20°C~+50°C;

(2) Ukufuma okuhambelanayo: 5% ~ 95%;

(3) Ukuphakama: ≤2000m;

(4) Umthamo wenyikima: ukukhawulezisa okuthe tyaba komhlaba yi-0.3g, ukukhawulezisa okuthe nkqo komhlaba yi-0.15g, kwaye izixhobo kufuneka zikwazi ukumelana namaza amathathu e-sine asebenza ngaxeshanye, kwaye into yokhuseleko kufuneka ibe nkulu kune-1.67.

Iimfuno zokuxhathisa kokusingqongileyo:

(1) Inqanaba lokhuseleko lweev itshajaiqokobhe kufuneka ifikelele: IP32 yangaphakathi; IP54 ngaphandle, kwaye ixhotyiswe ngemvula eyimfuneko kunye nezixhobo zokukhusela ilanga.

(2) Iimfuno ezintathu zokuchasana (ubungqina bokufuma, ukungunda, ukutshiza ityuwa): ukhuseleko lwebhodi yesekethe eprintiweyo, izihlanganisi kunye nezinye iisekethe kwitshaja kufuneka ziphathwe ngokhuseleko lokufuma, ukubola, kunye nokukhusela ityuwa, ukwenzela ukuba itshaja ikwazi ukusebenza ngokuqhelekileyo kwindawo efumileyo yangaphandle kunye netyuwa.

(3) I-Anti-rust (i-anti-oxidation) ukhuseleko: Iqokobhe lentsimbi yeisikhululo sokutshaja evkunye nesibiyeli sentsimbi esiveziweyo kunye namalungu kufuneka athathe amanyathelo aphindwe kabini achasene nomhlwa, kwaye iqokobhe lesinyithi elingenantsimbi kufuneka nalo libe nefilimu ekhuselayo yokulwa ne-oxidation okanye unyango lokuchasana ne-oxidation.

(4) Iqokobhe leev ukutshaja imfumbaiya kukwazi ukumelana novavanyo lwamandla empembelelo oluchazwe kwi-8.2.10 kwi-GB 7251.3-2005.

2. Iimpawu zesakhiwo seshiti lentsimbi yokutshaja igobolondo lemfumba

Iinqwaba yokutshajangokubanzi yenziwe ngumzimba wemfumba otshajayo, aisiseko sokutshaja, isixhobo sokulawula ukhuseleko, isixhobo sokulinganisa, isixhobo sokuswayipha ikhadi, kunye ne-interface yokusebenzisana nekhompyutha yomntu, njengoko kuboniswe kumzobo ongezantsi.

Iphephaisakhiwo metal ukutshaja imfumbayenziwe ngepleyiti yentsimbi ephantsi kwekhabhoni enobunzima obumalunga ne-1.5mm, kwaye indlela yokucubungula ithatha i-sheet metal tower punching, igoba, kunye nenkqubo yokwenza i-welding. Ezinye iintlobo zeemfumba zokutshaja zenzelwe kunye nesakhiwo esiphindwe kabini ngokuqwalasela iimfuno zokukhusela ngaphandle kunye nokushisa ukushisa. Ubume ngokubanzi bemveliso ubukhulu becala buxande, isakhelo sidityanisiwe sisonke, ukuze kuqinisekiswe ubuhle bembonakalo, indawo ejikelezileyo yongezwa kwindawo, kwaye ukuze kuqinisekiswe amandla ayo onke.iimfumba zokutshaja isithuthi sombane, ngokuqhelekileyo idityaniswe ngee-stiffeners okanye iipleyiti zokuqinisa.

Umphandle wemfumba ucwangciswe ngokubanzi ngezalathi zephaneli, amaqhosha ephaneli,ujongano lokutshajakunye nemingxuma yokutshatyalaliswa kobushushu, njl., umnyango ongasemva okanye icala lixhotyiswe nge-lock anti-theft lock, kwaye inqwaba igxininiswe kwisiseko sofakelo ngeebholiti ze-anchor.

Iifasteners ngokubanzi zenziwe nge-electro-galvanized okanye insimbi engenasici. Ukuze kuqinisekiswe ukuba iisikhululo sokushaja imoto yombaneUmzimba unokumelana nokugqwala okuthile, imfumba yokutshaja itshizwa ngokubanzi ngomgubo wangaphandle wokugquma okanye ipeyinti yangaphandle iyonke ukuqinisekisa ubomi bayo benkonzo.

3. Uyilo lwe-anti-corrosion yesakhiwo se-sheet metalinqwaba yokutshaja

(1) Ukubonakala kwesakhiwo semfumba yemfumba yokutshaja akufanele kuqulunqwe ngeekona ezibukhali.

(2) Kucetyiswa ukuba isiciko esiphezulu seev ukutshaja imfumbainothambeka olungaphezulu kwe-5° ukuthintela ukufumba kwamanzi ngaphezulu.

(3) Isitshizisi sisetyenziselwa ukuphelisa umswakama kwiimveliso ezitywiniweyo ukuthintela ukujiya. Kwiimveliso ezineemfuno zokulahla ubushushu kunye nemingxuma evulekileyo yokuchitha ubushushu, isilawuli sokufuma + isifudumezi kufuneka sisetyenziselwe ukukhupha amanzi ukuthintela ukujiya.

4IP54 ingangeni manziiimfuno.

(5) Kwizakhiwo ezitywiniweyo ezitywiniweyo ezifana ne-stiffeners yepaneli yomnyango, ukutshiza akunakungena ngaphakathi kwesakhiwo sokutywina, kwaye uyilo luphuculwe ngokutshiza kunye nokudibanisa, okanye i-galvanized sheet welding, okanye i-electrophoresis kunye nokutshiza emva kwe-welding.

(6) Ulwakhiwo oludityanisiweyo kufuneka lugweme izithuba ezimxinwa kunye nezithuba ezimxinwa ezingenakungena ngemipu yokutshiza.

(7) Imingxuma yokulahla ubushushu kufuneka iyilwe njengamacandelo kangangoko kunokwenzeka ukuphepha i-welds emxinwa kunye ne-interlayers.

(8) Intonga yokutshixa ethengiweyo kunye nehenjisi kufuneka yenziwe nge-304 yentsimbi engenasici kangangoko, kwaye ixesha lokumelana nokutshiza ityuwa elingathathi hlangothi akufanele libe ngaphantsi kwe-96h GB 2423.17.

(9) I-nameplate igxininiswe ngeerivethi ezingaboniyo ezingangeni manzi okanye intlama yokuncamathelisa, kwaye unyango olungenamanzi kufuneka lwenziwe xa lufuna ukulungiswa ngezikrufu.

(10) Ukukhethwa kwazo zonke i-fasteners kufuneka ziphathwe nge-zinc-nickel alloy plating okanye i-304 insimbi engenasici, i-zinc-nickel alloy fasteners idibana novavanyo lwe-salt spray olungathathi hlangothi lwe-96h ngaphandle kwe-rust emhlophe, kwaye zonke i-fasteners eziveziweyo zenziwe nge-304 yensimbi engenasici.

(11) Izibophelelo ze-zinc-nickel alloy akufanele zisetyenziswe ngokubambisana nensimbi engenasici.

(12) Umngxuma iankile wofakelo lweiposi yokutshaja imoto eviya kucutshungulwa kwangaphambili, kwaye umngxuma awuyi kugrunjwa emva kokubekwa kwemfumba yokutshaja. Umngxuma wokungena osemazantsi emfumba yokutshaja kufuneka uvalwe ngodaka olungatshiyo ukuthintela ukufuma okungaphezulu ekungeneni kwingqumba ukusuka kumngxuma wokungena. Emva kokufakwa, i-silicone sealant ingasetyenziswa phakathi kwemfumba kunye netafile yokufakela i-samente ukuqinisa ukutywinwa kwezantsi kwemfumba.

Emva kokufunda ezi mfuno zobugcisa zingasentla kunye noyilo oluchasene nomhlwa kwigobolondo lentsimbi yokutshaja, ngoku uyazi ukuba kutheni ixabiso lemfumba yokutshaja enegunya elifanayo lokutshaja liya kwahluka kakhulu?
