Iyiphi ikhebula le-DC splar elingcono kakhulu kusistimu yelanga

Ukukhetha i-DC efaneleikhebula lelangausayizi ohlelweni lwe-solar photovoltaic lubalulekile kokubili ukusebenza nokuphepha. Izintambo zidinga usayizi ofanele ngokuya nge-current kanye ne-voltage esetshenziswa ohlelweni. Intambo yelanga yase-China H1Z2Z2-K nekhebula lelanga Lekhwalithi Ephezulu 62930 IEC 131 zidumile.

Ugqinsi lwe-cable core ngokuvamile luyi-mm2. Le ndawo imelela indawo engaphezulu ye-cable core. Osayizi bezintambo abavamile bokufakwa kwe-solar photovoltaic yilezi: 2.5-4-6-10-16-25-35 mm2.

 Kunezinhlobo ezilandelayo zezintambo:

1. phakathi kwamabhethri kanye ne-inverter, 35 noma 25 mm2

2. kusuka kumaphaneli elanga ukuze kushaje isilawuli kumabhethri angu-10, 6 no-4 mm2.

3. kusukela ku-inverter kuya kugridi, 4 no-2.5 ​​mm2

Esigabeni ngasinye, kufanele usebenzise i-amperage efanele, ubude bekhebula, nokulahlekelwa kwamandla kagesi okwamukelekayo (namandla). Ukuze wazi ubukhulu be-diameter yekhebula elinemicu, bheka i-insulation yekhebula. Kunophawu ekhebulani elibonisa ukujiya komgogodla wekhebula.

62930 IEC 131 ikhebula lelanga Osayizi bekhebula bano-2.5 ​​- 4 - 6 - 10 - 16 - 25 - 35 mm2,Osayizi beCable ye-Copper eTinned Double Core Solar bano-2*2.5mm2,2*4mm2,2*6mm2.2*10mm2.China H1Z2Z2 -K osayizi be-Solar Wire bano-2.5 ​​- 4 - 6 - 10 - 16 - 25 - 35 mm2.

Lezi zintambo zibamba i-direct current (DC) ekhiqizwa ama-solar panel futhi agcinwa kumabhethri. Zihlanganisa:

Amakhebuli emojuli ye-PV:Lezi zintambo zixhuma ama-solar panel kusilawuli sokushaja, esilawula ukuhamba kwamandla ebhange lebhethri. Izintambo zemojula ye-PV ngokuvamile ziyi-10-12 AWG (i-American Wire Gauge), izintambo zelanga ezifakwe kabili eziklanyelwe ukuphatha ukuphuma kwe-DC kumaphaneli elanga.

Izintambo Zebhethri:Izintambo zebhethri zixhuma ibhange lebhethri kusilawuli sokushaja kanye ne-inverter. Banomthwalo wemfanelo wokuthwala amandla e-DC phakathi kwalezi zingxenye. Izintambo zebhethri zivamise ukuba zinkulu ngosayizi, kusukela ku-2-4/0 AWG, kuye ngomthamo wesistimu kanye namandla amanje adinga ukuwuphatha.

Amakhebuli e-Inverter:Lezi zintambo zixhuma i-inverter ebhange lebhethri, idlulisela amandla e-DC ukusuka kumabhethri kuya ku-inverter. Izintambo ezishintshashintshayo ngokuvamile zifana ngosayizi wezintambo zebhethri, ngokuvamile ezingu-2-4/0 AWG, ukuze zibambe isimanje esidingekayo phakathi kwebhange lebhethri nesiguquli.
