Uyini umehluko phakathi kwebhokisi lokuhlanganisa le-AC ne-DC?

I-AC (Alternating Current) kanye ne-DC (Direct Current)amabhokisi okuhlanganisasebenzisa izinjongo ezihlukene ezinhlelweni zikagesi, ikakhulukazi ezinhlelweni zamandla avuselelekayo afana nokufakwa kwe-solar photovoltaic (PV).

Amabhokisi okuhlanganisa i-AC asetshenziselwa ukuhlanganisa amasekhethi e-AC amaningi asuka kuma-solar inverters noma eminye imithombo ye-AC. Lawa masekhethi aphatha i-alternating current, okuwuhlobo lwamanje oluvame ukusetshenziswa ezinhlelweni zikagesi zasendlini nezohwebo.

Ibhokisi le-DC Combiner:Amabhokisi okuhlanganisa ama-DC, ngakolunye uhlangothi, asetshenziselwa ukuhlanganisa izintambo eziningi ze-DC noma amaphaneli elanga ngaphambi kokuba axhunywe ku-inverter yelanga. Lezi zintambo noma ama-arrays akhiqiza amandla aqondile, okuwuhlobo lwamanje olukhiqizwa ama-solar panel.

Amabhokisi enhlanganisela ye-AC ngokuvamile aphatha amazinga aphansi kagesi ngenxa yokuthi abhekana nokuphumayo okuvela eziguquguqukayo, eziguqula i-DC iye ku-AC ngama-voltage afanele ukuxhumana kwegridi (isb., 120V, 240V, 480V).

I-DC Combiner Box: Amabhokisi enhlanganisela ye-DC kufanele aphathe amazinga kagesi aphezulu ngoba abhekene nokuphuma kwe-DC okungaphekiwe okuvela kumaphaneli elanga, okungasukela kumakhulu amaningana ama-volts kuye kwangaphezu kuka-1,000 volts kuye ngokucushwa nosayizi wesistimu.

Izingxenye ezisebhokisini lesihlanganisi se-AC, njengama-circuit breaker noma ama-fuse, ngokuvamile zilinganiselwe izinhlelo zokusebenza ze-AC futhi zingaba nokucaciswa okuhlukile uma kuqhathaniswa nalezo ezisetshenziswa kumabhokisi okuhlanganisa e-DC.

Ibhokisi Lenhlanganisela Ye-DC: Izingxenye ezisebhokisini lokuhlanganisa i-DC, okuhlanganisa ama-fuse, ama-circuit breaker, nezivikeli zokuhlinza, kufanele zakhelwe ngokuqondile futhi zilinganiselwe izinhlelo zokusebenza ze-DC ngenxa yezimpawu ezihlukile zikagesi we-DC.

Ukucatshangelwa kokuphepha:

Ukucatshangelwa kokuphepha kwamabhokisi esihlanganisi se-AC kugxile ekuvikeleni kumasekethe adlulele kakhulu namafushane, kanye nokuhlinzeka ngezindlela zokuhlukanisa nokunqamula njengoba kudingwa amakhodi kagesi.

Ngokungeziwe ekuvikelweni okudlulele kanye nokufushane kwesekethe, izinyathelo zokuphepha zamabhokisi enhlanganisela ye-DC futhi zihlanganisa ukuvikela ngokumelene nokufaka i-arcing nokwehluleka kokufakwa ngenxa yamandla aphezulu aphezulu ahilelekile.

Ngamafuphi, i-AC kanyeAmabhokisi okuhlanganisa ama-DCziyahlukahluka ngokuya ngohlobo lwamanje abaluphathayo, amazinga kagesi, ukukhethwa kwengxenye, nokucatshangelwa kokuphepha. Badlala indima ehlukile ezinhlelweni zamandla avuselelekayo futhi kufanele zikhethwe futhi zifakwe ngokufanele ngokuya ngezidingo ezithile zohlelo.
