Isihloko: Ukuqonda ukubaluleka kwee-frequency converters kwiizixhobo zokuguqula amaza
Isiqendu 1:
Abaguquli befrikhwensizidlala indima ebalulekileyo kubuchwepheshe banamhlanje, ingakumbi kwiizixhobo zefrikhwensi eziguquguqukayoNokuba siyazi okanye asiziqondi, ezi zixhobo zisijikelezile, zinika amandla usetyenziso olwahlukeneyo kumashishini afana nokuvelisa, i-HVAC (ukufudumeza, ukuphefumla, kunye ne-air conditioning), kunye neenkqubo zamandla avuselelekayo. Kule bhlog, siza kungena nzulu kwihlabathi lee-frequency converters kwaye sixoxe ngokubaluleka kwazo ekusebenzeni.izixhobo zefrikhwensi eziguquguqukayo.

Ukuqonda ukubalulekaabaguquli befrikhwensi, umntu kufuneka aqale aqonde iingcamango ezisemva kwezixhobo zokuguqula amaza.Izixhobo zokuguqula iifrikhwensiyinkqubo yombane evumela umsebenzisi ukuba alawule isantya okanye imvamisa yamandla okukhupha. Olu lawulo luphuculweyo lwenza kube lula ukusebenza kakuhle kunye nokuchaneka okukhulu kwizicelo ezininzi. Eli liphuzu elikhanyayo le-frequency converter! Zizixhobo ze-elektroniki eziguqula igalelo le-fixed frequency alternating current (AC) libe yi-variable frequency output, ezibonelela ngolawulo oluchanekileyo olufunekayo ukuze kuphuculwe ukusebenza kwenkqubo.

Kwiindawo zoshishino,abaguquli befrikhwensizisetyenziswa kakhulu ukulawula isantya seemoto zombane. Ngokulungisa isantya, isantya semoto sinokulungiswa ngokweemfuno ezithile zokusebenza. Oku kuguquguquka akuqinisekisi nje kuphela ukusebenza kakuhle koomatshini, kodwa kunciphisa nokusetyenziswa kwamandla. Umzekelo, imoto esebenza ngesantya esipheleleyo xa kuphela inxalenye yamandla efunekayo inokusebenzisa amandla amaninzi kunoko kufunekayo. Abaguquli besantya banokulawula isantya semoto kancinci kancinci ukuze bahambelane ngokuchanekileyo nesicelo, bonge amandla kwaye bandise ubomi bezixhobo.

Ukwengeza,izixhobo zefrikhwensi eziguquguqukayoezixhotyiswe ngee-frequency converters zinceda ekunciphiseni uxinzelelo loomatshini kwizixhobo. Ezi inverters ziyakwazi ukuqalisa imoto ngesantya esiphantsi kwaye ziyikhawulezise kancinci kancinci ukuya kwisantya esifunekayo, ngaloo ndlela zikhusela ekunyukeni kwamandla ngequbuliso kwaye zisuse ukuqhawuka koomatshini okunokubangela ukuguguleka nokonakala kwangethuba. Ngokunciphisa uxinzelelo loomatshini, amashishini anokuphepha ukulungiswa okubiza kakhulu kwaye agcine ukusebenza kakuhle.

Ii-frequency converters nazo zenze igalelo elikhulu kwishishini le-HVAC. Iiyunithi zokuphatha umoya, iifeni kunye neempompo kwiinkqubo ze-HVAC zidla amandla amaninzi. Nangona kunjalo, ngokusetyenziswa kwezixhobo ze-frequency eziguquguqukayo kunye nee-frequency converters, ukusetyenziswa kwamandla kunokulungiswa. I-inverter ilawula isantya sala macandelo ngokweemfuno zexesha langempela, iphephe ukusetyenziswa kwamandla okungeyomfuneko ngamaxesha emfuno ephantsi. Olu lawulo luchanekileyo alugcini nje ngokugcina amandla, kodwa lukwanciphisa amanqanaba engxolo, luphucula intuthuzelo kwaye lunciphisa iindleko zokugcina.

Iinkqubo zamandla avuselelekayo, ezifana nee-solar photovoltaics (PV) kunye nee-wind turbines, zixhomekeke kakhulu kwiabaguquli befrikhwensiukulawula amandla aveliswayo. Ezi inverters ziguqula umsinga othe ngqo (DC) ube ngumsinga otshintshanayo ukuze uhambelane neemfuno zefrikhwensi kunye nevolthi yegridi yombane. Ukongeza,abaguquli befrikhwensiukuqinisekisa ukuguqulwa kwamandla okusebenzayo, ukwandisa imveliso yamandla iyonke kunye nokuphucula ukuthembeka kwenkqubo. Njengoko imfuno yamandla avuselelekayo ikhula, abaguquli bamaza baya kuqhubeka nokudlala indima ebalulekileyo ekudibaniseni ngokungenamthungo le mithombo yamandla eguquguqukayo kwigridi.

Ukuququmbela,abaguquli befrikhwensizingumqolo wezixhobo ze-variable frequency, ezibonelela ngolawulo olusisiseko kunye nokuchaneka okufunekayo kwiintlobo ngeentlobo zezicelo. Ukusuka kulawulo lweemoto zoshishino ukuya kushishino lwe-HVAC kunye neenkqubo zamandla avuselelekayo, ezi zixhobo ziphucula ukusetyenziswa kwamandla, zinciphisa uxinzelelo loomatshini kwaye zonyusa ukusebenza kakuhle kwenkqubo iyonke. Ngokuhambela phambili kwezobuchwepheshe kunye nokuzinza phambili, ii-drive ziya kuqhubeka nokukhula, ziqhuba ubuchule kwaye zinegalelo kwikamva elisebenzisa amandla kakuhle.
