Kubunjineli bombane, iinkcukacha zokufakela ukusabalalisa iingcingo zokumisa ikhabhinethi zihambelana ngqo nezixhobo kunye nokhuseleko lwabasebenzi. Ukudibanisa umgangatho wesizwe we-GB/T 7251.1-2023 kunye neemeko eziphathekayo, iingongoma eziphambili zezi zilandelayo:
1. Iikhrayitheriya zokuKhetha iiNcingo zoMhlaba
Mthubi -izibhengezo zobhedu eziluhlaza kufuneka zisetyenziswe, kwaye indawo enqamlezileyo -indawo yecandelo kufuneka iphindwe kabini{2}}itshekishwe: umthamo wangoku wokuthwala ubalwa kusetyenziswa ifomula S=I / (K × J) ukuqinisekisa ukuba akukho kunyibilika phantsi kweemeko zokusebenza ezinzima; iimfuno zamandla oomatshini zifuna ukuba izitsibi zocango lwekhabhathi zibe Khulu okanye zilingane ne-4mm², kwaye iingcingo eziphambili zokumisa zibe Khulu okanye zilingane ne-16mm². Kwiprojekthi, ukusetyenziswa kakubi kocingo lwe-2.5mm² kwisekethe ye-16A kubangele i-carbonization ye-insulation, igxininisa ukubaluleka kokukhetha okuthobelayo. Kwimodeli yokubala yemeko eqhelekileyo, umzekelo, xa intambo ye-35mm² ingcwatywe kwi-40℃, umthamo wangoku okhuselekileyo wokuthwala kufuneka ulungiswe kubushushu (140A → 132A → 119A).
2. Izikhokelo zoFakelo
1) I-Bracket Prefabrication: Izibiyeli kufuneka zihlukaniswe i-1-1.5 yeemitha ngaphandle kodonga, i-250-300 mm ukusuka emhlabeni, kwaye igcine i-10-15 mm isithuba ukusuka eludongeni.
I-2) Inkcazo ye-Welding: I-Flat steel overlaps Enkulu kunokuba okanye ilingana namaxesha ama-2 ububanzi kufuneka idityaniswe kumacala amathathu, kwaye i-welding yentsimbi ejikelezileyo Inkulu kunokuba okanye ilingana namaxesha ama-6 ububanzi kufuneka idityaniswe macala omabini. Iiwelds kufuneka ziphathwe ngokhuseleko lomhlwa.
3) I-Crimping: Iingcingo ezininzi -zemicu kufuneka zicolwe kusetyenziswa iilugi zobhedu. Ukufa kufuneka kuhambelane ne-GB / T 14315-2008. Umzekelo, i-hexagonal die kufuneka isetyenziswe kwi-35 mm² ucingo (i-indentation Enkulu kuno okanye ilingana no-0.4 mm). Emva kwe-crimping, iingcingo kufuneka ziphumelele uvavanyo lwe-tensile.
I-4) UQinisekiso oluqhubekayo: Ikhabhinethi kunye ne-busbar yomhlaba kufuneka idibaniswe kwiindawo ezininzi, kunye nokuchasana okungaphantsi okanye okulinganayo no-0.1 Ω.
5) Iimpawu zokuMakisha: Intambo yonke kufuneka ipeyintwe ngemigca etyheli{1}}eluhlaza, kwaye iitheminali kufuneka zibhalwe ngokusisigxina.
6) Iimeko eziKhethekileyo: Inkqubo yokumisa kabini kufuneka isetyenziswe kwiindawo ezinobungqina obuqhumayo -, ngokumelana okuNgaphantsi okanye okulingana no-4 Ω.
3. IiNdawo zoKwamkelwa eziPhambili
1) Umsebenzi ofihliweyo: Gxininisa ekuhloleni umgangatho we-welding phakathi kwekhabhinethi ephantsi kunye nesiseko sentsimbi yentsimbi;
2) I-Equipotential Bonding: Isiseko sesekethe sesibini kufuneka siqhagamshelwe kwi-bar grounding busbar;
3) Ukuqinisekiswa kwezinto eziphathekayo: Khangela isatifikethi somqhubi kunye nobukhulu bokugquma (umzekelo, i-zinc coating Enkulu okanye ilingana ne-40μm);
4) Uvavanyo oluSebenzayo: Ukongeza kuvavanyo oluqhubekayo, i-2000V / 1min yamandla ombane wokumelana novavanyo olufunekayo.
4. Amanqaku oLawulo oluPhambili kunye noLondolozo
I-1) Ukuhlolwa kwekota: Vavanya ukuchasana komhlaba kwaye uhlolisise iingcingo ze-jumper ze-hinge emnyango;
2) Unyango{1}}lokuthintela ukudleka: Faka ipeyinti ekhuselayo{2}}ethintela ukubola kwisixhobo sangaphandle rhoqo emva kweminyaka emibini, kwaye ngonyaka kwiindawo eziselunxwemeni;
I-3) Ukuphuculwa kweNkqubo: Xa ukwandiswa kwamandla kudlula ixabiso lokuqala lokuyila nge-30%, ikhebula elisezantsi kufuneka liphuculwe ngaxeshanye.
Ukulandela ngokungqongqo iinkqubo ezisemgangathweni kunye nokuphunyezwa kolawulo{0}}loluphu oluvaliweyo kwinqanaba ngalinye, ukusuka ekukhetheni ukuya kulungiso, kuya kuqinisekisa ukhuseleko oluluqilima lombane.
