Iimeko zokusingqongileyo
1. Ubushushu bomoya okhoyo awukho ngaphezulu kwe +40℃kwaye ungabi ngaphantsi kwe -5℃.Iqondo lobushushu eliphakathi kwiiyure ezingama-24 aliyi kuba ngaphezulu kwe +35℃.
2. Ufakelo lwangaphakathi kunye nokusetyenziswa, ukuphakama kwendawo yokusetyenziswa akuyi kudlula i-2000m.
3. Umswakama ohambelana nomoya ojikelezayo awudluli i-50% xa iqondo lokushisa eliphezulu liyi +40℃, kunye nomswakama ophezulu ophezulu uvumelekile kwiqondo lokushisa eliphantsi: (umzekelo, 90% kwi +20℃), kufuneka kuthathelwe ingqalelo ukuba ubushushu bunokutshintsha Impembelelo yengozi yokujiya.
4. Xa izixhobo zifakwe, ukuthambekela ukusuka kwinqwelo-moya ethe nkqo akufanele kudlule i-5°.
5. Isixhobo kufuneka sifakwe kwiindawo apho kungekho kungcangcazela okukhulu kunye neempembelelo, kunye neendawo apho amacandelo ombane angenawo umhlwa.
6. Xa umsebenzisi eneemfuno ezizodwa, inokusombulula ngokubonisana nomenzi.
Umzekelo kunye nentsingiselo yawo
Ezona Parameters zobuGcisa
1. Iiparamitha ezisisiseko zombane ziboniswe kwiThebhile 1

2. Iskim sesekethe esincedisayo
Uyilo lwesekethe encedisayo luhlulwe lube ngamacandelo amabini: isicwangciso sokubonelela ngombane kunye nesicwangciso seplanti yamandla.
3. Ibhasi engundoqo
Xa umlinganiselo wangoku uyi-1500A nangaphantsi, kusetyenziswa ibhasi enye yobhedu.Xa umlinganiselo wangoku ungaphezu kwe-1500A, ibhasi ephindwe kabini yobhedu isetyenziswa.Imiphezulu egqitheneyo yeebhasi zonke ziphathwa nge-tin lining.
4. Ukukhethwa kwamacandelo ombane
a.Ikhabhinethi yeGGD ithatha ubukhulu becala amacandelo ombane angaphezulu anokuveliswa ngobuninzi eTshayina.Njenge DW17, DZ20, DW15, njl.
b.I-1ID13BX kunye ne-HS13BX i-rotary-operated knife switches zizinto ezikhethekileyo ezenzelwe yi-NLS ukuhlangabezana neemfuno zesakhiwo esikhethekileyo sekhabhinethi yeGGD.Itshintsha indlela yokusebenza yendlela kwaye igcina izibonelelo zeemveliso ezindala.Luhlobo olutsha olusebenzayo lwecandelo lombane.
c.Ngokomzekelo, xa isebe loyilo likhetha amacandelo ombane amatsha kunye nokusebenza kakuhle kunye nobuchwepheshe obuphezulu ngokweemfuno zabasebenzisi, kuba ikhabhinethi ye-GGD ine-flexibility efanelekileyo yokufakela, ngokuqhelekileyo ayiyi kubangela ubunzima bokuvelisa kunye nokufakwa ngenxa yezinto ezihlaziyiweyo zombane.
d.Ukuze kuphuculwe ngakumbi ukuzinza kwesekethe, inkxaso yebhasi yeKhabhinethi yeGGD ithatha uhlobo oluzinikeleyo lwe-ZMJ oludityanisiweyo lwebhasi kunye nenkxaso ye-insulating.I-clamp ye-busbar yenziwe nge-high-high-high-flame-retardant PPO imathiriyeli edibeneyo ye-PPO, enegunya eliphezulu lokugquma, ukusebenza kakuhle kokuzicima, kunye nesakhiwo esisodwa.Inokudibaniswa lula ibe yibhasi enye okanye i-double busbar clamp ngokulungelelanisa ibhloko yokwakha.Inkxaso yokukhusela i-sleeve-uhlobo olubunjiweyo olubunjiweyo olunexabiso eliphantsi kunye namandla aphezulu, okusombulula iziphene zomgama onganeleyo we-creepage yeemveliso ezindala.
Oda Imiyalelo
Xa uodola, umsebenzisi kufuneka anike le datha ilandelayo:
1. Imodeli epheleleyo yemveliso (kubandakanywa nenombolo yesikim sesekethe engundoqo kunye nenombolo yesikim sesekethe encedisayo).
2. Umzobo wokulandelelana kwenkqubo yesekethe engundoqo.
3. Umzobo weskimu sombane wesekethe encedisayo.
4. Uluhlu lwamacandelo kwikhabhinethi.
5. Ezinye iimfuno ezikhethekileyo ezingahambelani neemeko eziqhelekileyo zokusetyenziswa kwemveliso.
