GusobanukirwaAbarinda DC Surge: Ni ngombwa kugira ngo umutekano w'amashanyarazi ugerweho
Muri iki gihe, hamwe n’uko ibikoresho by’ikoranabuhanga n’ingufu zisubira birushaho gukundwa, akamaro ko kurinda ingufu z’amashanyarazi ntigakwiye gusuzugurwa. DC surge protector (DC SPD) ni kimwe mu bintu by’ingenzi mu kurinda izi gahunda. Iyi nkuru irasuzuma byimbitse icyo DC surge protector isobanura, imikorere n’ikoreshwa ryayo, yibanda ku ruhare igira mu gutuma ingufu z’amashanyarazi ziramba kandi zizewe.
Ikirinda DC surge ni iki?
Utwuma dukingira umuriro wa DC twagenewe kurinda ibikoresho by'amashanyarazi ubwiyongere bw'amashanyarazi buterwa n'inkuba, ibikorwa byo guhinduranya, cyangwa ibindi bintu by'agateganyo. Bitandukanye n'utwuma dusanzwe dukingira umuriro wa AC dukoreshwa mu ngo no mu bucuruzi, utwuma dukingira umuriro wa DC twagenewe gukoreshwa muri DC. Ibi bituma tuba ingenzi mu kurinda sisitemu z'amashanyarazi zikomoka ku mirasire y'izuba, sisitemu zo kubika ingufu za bateri, n'ibindi bikoresho bikoresha DC.
Ibikoresho byo kurinda DC surge bikora bite?
Imashini irinda umuvuduko wa DC (SPD) ikora ikoresheje uburyo bwo gukuramo ingufu nyinshi ku bikoresho by’ikoranabuhanga. Iyo umuriro ubaye mwinshi, igikoresho kibona ubwiyongere bw’amashanyarazi hanyuma kigatangiza uburyo bwo kurinda, akenshi gikoresha ibice nka metal oxide varistors (MOVs) cyangwa imiyoboro isohora umwuka (GDTs). Ibi bice bikurura ingufu nyinshi hanyuma bikayohereza ku butaka, bikayibuza kugera ku bikoresho bihujwe.
Ubusanzwe ubushobozi bw'icyuma gikingira umuvuduko wa DC bupimirwa ku muvuduko wacyo wo gufunga, igihe cyo gusubiza, n'ubushobozi bwo kwinjiza ingufu. Uko umuvuduko wa clamping uba muto, ni ko uburinzi burushaho kuba bwiza, kuko bivuze ko igikoresho gishobora kugabanya umuvuduko wa volteji ugera ku gikoresho. Byongeye kandi, igihe cyo gusubiza vuba nacyo ni ingenzi kugira ngo bigabanye igihe cyo guhura n'umuvuduko.
Gukoresha uburyo bwo kurinda DC surge
Ibikoresho birinda umuvuduko wa DC ni ingenzi mu bikorwa bitandukanye, cyane cyane muri sisitemu y'ingufu zishobora kuvugururwa. Dore bimwe mu bice by'ingenzi bikunze gukoreshwa n'ibikoresho birinda umuvuduko wa DC:
1. Sisitemu zo kubyaza ingufu z'izuba: Uko ingufu z'izuba zigenda zirushaho gukundwa n'abantu benshi, niko gukenera uburyo bwo kurinda ingufu z'izuba neza muri sisitemu za photovoltaic (PV) bigenda byiyongera. Ibikoresho byo kurinda ingufu z'izuba bya DC (SPDs) bishyirwa ku rwego rwa inverter na combiner box kugira ngo hirindwe kwiyongera kw'izuba bishobora kwangiza panels z'izuba na inverters.
2. Sisitemu yo kubika ingufu za bateri: Kubera ko hari uburyo bwinshi bwo kubika ingufu, ni ngombwa kurinda sisitemu za bateri kwiyongera k'umuvuduko w'amashanyarazi. Ibikoresho bikingira umuvuduko wa DC (SPDs) birinda kwangirika kw'umuvuduko ushobora kubaho mu gihe cyo gusharija no gusohora umuriro, bigatuma bateri ihora ikora neza kandi irambye.
3. Itumanaho: Mu itumanaho, DC SPDs zikoreshwa mu kurinda ibikoresho by’ingenzi nka za routers, switches, n’imiyoboro y’itumanaho amashanyarazi ashobora guhagarika serivisi bigatuma ibikoresho binanirwa.
4. Ibinyabiziga bikoresha amashanyarazi (EV): Uko imodoka zikoresha amashanyarazi ziyongera, ni nako hakenewe uburinzi bw'amashanyarazi ku bigo bikoresha amashanyarazi (EV charger stations). Ibikoresho bikingira amashanyarazi bya DC (SPDs) bifasha mu kurinda ibikorwa remezo byo gusharija amashanyarazi ku ngufu zishobora kwiyongera mu gihe cyo gusharija.
Muri make
Muri make, ibikoresho birinda umuvuduko wa DC bigira uruhare runini mu kurinda sisitemu z'amashanyarazi kwiyongera k'amashanyarazi kwangiza. Hamwe n'iterambere rikomeje mu ikoranabuhanga no kwiyongera kw'uburyo bwo kwishingikiriza ku bikoresho bikoresha DC, akamaro ko gushyira mu bikorwa ingamba zinoze zo kurinda umuvuduko ntigashobora kwirengagizwa. Mu gushora imari mu bikoresho birinda umuvuduko wa DC byiza, abantu ku giti cyabo n'ibigo bashobora kwemeza ko sisitemu zabo z'amashanyarazi zirangwa n'umutekano, icyizere, no kuramba, amaherezo bikagabanya igihe cyo kudakora n'ikiguzi cyo kubungabunga. Uko tugenda tugana ahazaza h'amashanyarazi, gusobanukirwa no gukoresha uburyo bwo kurinda umuvuduko wa DC ni ingenzi ku muntu wese ufite uruhare mu gushushanya, gushyiraho, cyangwa kubungabunga sisitemu z'amashanyarazi.
