Malinga ndi IEC60228, ma conductor chingwe amagawidwa m'mitundu inayi, mtundu woyamba, wachiwiri, wachisanu ndi wachisanu ndi chimodzi.Mtundu woyamba ndi woyendetsa wolimba, mtundu wachiwiri ndi woyendetsa wokhotakhota, mtundu woyamba ndi wachiwiri umapangidwa kuti ugwiritsidwe ntchito pazingwe zokhazikika, zachisanu ndi zisanu ndi chimodzi zimapangidwira kuti zigwiritsidwe ntchito pazingwe zosinthika ndi zingwe, ndipo yachiwiri. Mtundu umapangidwira makondakitala a zingwe zosinthika ndi zingwe.Sikisi ndi yofewa kuposa yachisanu.
1. Kondakitala wokhazikika:
Waya wamkuwa wopangidwa ndi zitsulo kapena wosakulungidwa, waya wosatsekedwa wa aluminiyamu kapena waya wazitsulo zopangira zida zowongolera.
Zoyendetsa zamkuwa zolimba ziyenera kukhala zozungulira, 25mm2 ndi pamwamba pazitsulo zamkuwa zolimba zimapangidwira zingwe zapadera, osati zingwe zonse;Kwa oyendetsa aluminiyamu olimba, gawo la 16mm2 ndi pansi lidzakhala lozungulira, la 25mm2 ndi pamwamba, likhale lozungulira pazingwe zamtundu umodzi, ndipo zikhoza kukhala zozungulira kapena zooneka ngati zingwe zamitundu yambiri.
2. Kondakitala wa stranded:
Pofuna kuonjezera kusinthasintha kapena kupindika kwa chingwe, chingwe chachitsulo chokhala ndi gawo lalikulu la mtanda chimapangidwa ndi kupotoza mawaya angapo amodzi ndi awiri ang'onoang'ono.Waya wopindika ndi mawaya angapo amodzi amakhala ndi kusinthasintha kwabwino komanso kupindika kwakukulu.Chingwe cha waya chikapindika, mbali zamkati ndi zakunja za mzere wapakati wa waya zimatha kusuntha ndikubwezerana.Mukapinda, sizimayambitsa kusinthika kwa pulasitiki kwa woyendetsa, kotero kuti waya ndi wofewa.Kugwira ntchito ndi kukhazikika kumakhala bwino kwambiri.
Mawonekedwe a pachimake amatha kugawidwa m'mitundu iwiri, yokhazikika yokhazikika komanso yosakhazikika.Tanthauzo la ma kondakitala nthawi zonse ndi: kutsekeka kwa ma conductor mokhazikika, kukhazikika komanso zigawo zotsatizana m'njira zosiyanasiyana kumatchedwa kukhazikika pafupipafupi.Ithanso kugawidwa m'njira zokhazikika komanso zomangira zachilendo.Zotsirizirazi zimatanthawuza kusanjikiza-kwa-wosanjikiza Kutsekeka kokhazikika komwe kumakhala ndi ma diameter osiyana a waya, pomwe akale amatanthauza kuti ma diameter a mawaya omwe ali nawo ndi ofanana;Kumangirira kokhazikika kumathanso kugawidwa m'makona osavuta okhazikika komanso chingwe chokhazikika.Zotsirizirazi zikutanthawuza kuti mawaya omwe amapanga stranding nthawi zonse sali amodzi, koma amapotozedwa muzitsulo ndi mawaya ochepetsetsa malinga ndi malamulo, kenako amapindika muzitsulo., kupotoza kotereku kumagwiritsidwa ntchito kwambiri kusuntha pakati pa chingwe chotchinga cha rabara kuti chikhale chosinthika.Zomangika mosakhazikika (zomanga mtolo), mawaya onse amapindika mbali imodzi.
2.1 Makondakitala ozungulira osaphatikizana:
Gawo lamtanda la kondakitala wozungulira wozungulira wa aluminiyamu nthawi zambiri sichepera 10mm2.Mawaya amodzi mu kondakitala ayenera kukhala ndi mainchesi ofanana, ndipo kuchuluka kwa mawaya amodzi ndi kukana kwa DC kwa woyendetsa kuyenera kukwaniritsa miyezo.
2.2 Makondakitala ozungulira ozungulira ndi ma conductor owoneka bwino:
The mtanda gawo la zolimba stranded kuzungulira zotayidwa kondakitala sayenera kukhala zosakwana 16mm2, mtanda gawo la stranded mkuwa kapena aluminiyamu okonda sayenera kukhala zosakwana 25mm2, ndi m'mimba mwake chiŵerengero cha mawaya awiri osiyana limodzi kondakitala yemweyo sayenera upambana 2. , ndi chiwerengero cha mawaya amodzi ndi DC kukana kwa kondakitala ayenera kutsatira malamulo muyezo.
3. Kondakitala wofewa:
Makondakitala azikhala ndi waya wamkuwa wopukutidwa komanso wosapukutidwa.Mawaya ang'onoang'ono a kondakitala ayenera kukhala ndi mainchesi omwewo, m'mimba mwake mwa mawaya amodzi omwe ali mu kondakitala sayenera kupitirira mtengo womwe watchulidwa, m'mimba mwake wa kondakitala wachisanu ndi chimodzi ndi woonda kuposa wachisanu wachisanu wa waya umodzi, ndi woyendetsa. kukaniza sikuyenera kupitirira mtengo wapamwamba wotchulidwa muyeso.
