Ishishini lokugcina amandla liyinxalenye ebalulekileyo yenkqubo yamandla yanamhlanje. I-inverter idlala indima ezininzi kwinkqubo yokugcina amandla yanamhlanje, kubandakanya ukuguqulwa kwamandla, ulawulo kunye nonxibelelwano, ukhuseleko lokuzahlula, ulawulo lwamandla, ukutshaja nokukhupha amandla kwicala ngalinye, ulawulo olukrelekrele, ukhuseleko oluninzi kunye nokuhambelana okuqinileyo, okwenza i-inverter ibe yenye yezona zinto zibalulekileyo zenkqubo yokugcina amandla.
Ii-inverters zokugcina amandla zihlala zenziwe ziinkqubo zokufaka, zokukhupha kunye nezolawulo. Ii-capacitors zidlala indima kwi-inverter, kubandakanya ukuzinza kunye nokucoca i-voltage, ukugcinwa kunye nokukhululwa kwamandla, ukuphucula amandla, ukhuseleko kunye nokwenza i-DC pulsation ibe bushelelezi. Le misebenzi kunye iqinisekisa ukusebenza okuzinzileyo kunye nokusebenza kakuhle kwe-inverter. Kwiinkqubo zokugcina amandla, inokuphucula ukusebenza kunye nokuzinza kwenkqubo iyonke.
Iingenelo zee-capacitors ze-YMIN kwii-inverters
Uxinano oluphezulu lomthamo:
I-inverter ifumana umbane oveliswa zizixhobo zamandla avuselelekayo ezifana neepaneli zelanga okanye ii-wind turbines kwaye iwuguqula ube luhlobo lombane oluhlangabezana neemfuno. Kule nkqubo, ekubeni umthwalo wamandla unokwanda ngoko nangoko, i-inverter kufuneka ibe namandla okulawula amandla ukuqinisekisa umbane ophuma kakuhle.
Ii-capacitor ze-electrolytic ze-aluminium ze-YMINZinenzuzo yokuba nomthamo ophezulu wombane, onokugcina itshaja engaphezulu ngomthamo ofanayo, zihlangabezana ngokupheleleyo neemfuno zamandla ombane anokunyuka ngoko nangoko. Ekusebenzeni kwe-inverter, olu phawu luqinisekisa ukukhutshwa kwamandla ombane okugudileyo.
Ukumelana okuphezulu kombane ojikelezayo:
Ngexesha lokusebenza kwe-inverter, ukuba ukulungiswa kwamandla akwenziwanga, umbane kwimveliso yawo unokuba nenani elikhulu lezinto ze-harmonic. Ii-capacitors ze-YMIN aluminium electrolytic, ezinokumelana kwazo okulinganayo okuphantsi (ESR) kunye neempawu zazo eziphezulu ze-frequency, zinokunciphisa ngokufanelekileyo umxholo we-harmonic, kungekuphela nje ukuhlangabezana neemfuno zomthwalo zamandla e-AC asemgangathweni ophezulu, kodwa nokuqinisekisa ukuba i-inverter iyahambelana nemigangatho efanelekileyo yokufikelela kwigridi, ukunciphisa ukuphazamiseka kunye nempembelelo embi kwigridi.
Ukongeza, kwicala lokufaka i-DC ye-inverter, ii-capacitors ze-YMIN, ezinobuninzi be-capacitance kunye nokusebenza kakuhle kokucoca, zinokucoca ingxolo kunye nokuphazamiseka kumbane we-DC ongenayo, ziqinisekise ukuba umsinga wokufaka ucocekile, ngaloo ndlela zinciphisa impembelelo yeempawu zokuphazamiseka kwiindawo ezilandelayo zesekethe ye-inverter kwaye ziphucule ngokupheleleyo uzinzo kunye nokusebenza kakuhle kwenkqubo.
Inzuzo yokumelana nombane ophezulu:
Ngenxa yotshintsho kubunzulu bokukhanya, i-output voltage yenkqubo ye-photovoltaic isenokungazinzi, kwaye izixhobo ze-power semiconductor kwi-inverter nazo ziya kuvelisa i-voltage kunye ne-current spikes ngexesha lenkqubo yokutshintsha. Ezi spikes zinokubangela umonakalo kwizixhobo zamandla. Ke ngoko, i-buffer capacitor idlala indima ebalulekileyo ekutsaleni i-voltage kunye ne-current spikes kwaye ikhusele izixhobo zamandla kwi-voltage egqithisileyo okanye i-current shocks. Kwangaxeshanye, i-capacitor inokwenza utshintsho kwi-voltage kunye ne-current lube lula, inciphise ukulahleka kwamandla ngexesha lenkqubo yokutshintsha, kwaye ngaloo ndlela iphucule ukusebenza kakuhle kokuguqulwa kunye nokuzinza ngokubanzi kwe-inverter.
YMINIngcebiso yokukhetha i-capacitor kwi-inverter:
Shwankathela:
Ii-capacitor ze-YMINZiphucule ngokupheleleyo ukusebenza kwee-inverters kwiinkqubo zokugcina amandla ngeempawu zazo ezibalaseleyo ezifana nokumelana nombane ophezulu, uxinano oluphezulu lomthamo, i-ESR ephantsi, kunye nokumelana nombane onamandla we-ripple. Ayinciphisi nje kuphela ilahleko kwinkqubo yokuguqula amandla ngokusebenzisa iimpawu ezibalaseleyo zokucoca kunye nokulawula umbane, kodwa ikwanokulungisa umbane ngokuzinzileyo, umbane kunye nokuphindaphinda ukuqinisekisa imveliso ethembekileyo ngakumbi yenkqubo. Kwangaxeshanye, ii-capacitors zikhawuleza zifunxe ukuthuthumela okwethutyana kunye nokubetha kombane okuthambileyo, ziphucula ukuchasana nokuphazamiseka kwenkqubo kunye nozinzo. Ukongeza, ii-capacitors ze-YMIN zixhasa ngokufanelekileyo ukugcinwa kunye nokukhululwa kwamandla ngexesha lenkqubo yokutshaja nokukhupha, zikhulisa ukusebenza kakuhle kokusetyenziswa kwamandla kwenkqubo yokugcina amandla kwaye zinceda yonke inkqubo ukuba ifikelele ekusebenzeni kakuhle kokuguqula, ukuzinza okuqinileyo, kunye nokulahleka kwamandla okuphantsi.
