Iyiphi Ithonya Isilinganiso Sokuguqulwa Esinalo Kuhlelo Lwamandla?

Iyini isilinganiso se-transformer?

 

Isilinganiso sokuguqulwa kwe-transformer sibhekisela kusilinganiso se-voltage phakathi kokugoqa kwe-high-voltage (HV) kanye nokugoqa kwe-low-voltage (LV). Ngokukhethekile, simelela isilinganiso se-voltage elinganisiwe ohlangothini oluyinhloko (ngokuvamile olubizwa ngokuthi uhlangothi lwe-high-voltage noma lokufaka) ku-voltage elinganisiwe ohlangothini lwesibili (ngokuvamile olubizwa ngokuthi uhlangothi lwe-low-voltage noma lokukhipha).

 

Ngokwezibalo, isilinganiso sokuguqulwa (K) se-transformer singachazwa kanje:

 

K=I-Voltage Elinganisiwe ohlangothini lwe-High Voltage/I-Voltage Elinganisiwe ohlangothini lwe-Low Voltage

 

 

Ungabala kanjani isilinganiso sokuguqulwa kwe-transformer?

 

 

Kunezindlela eziningana zokubala zesilinganiso sokuguqulwa kwama-transformer:

 

 

1. Ukubala Isilinganiso Sokujika Ngokujika Kwekhoyili Okuyinhloko Kuya Kwesibili:

 

Ifomula: Isilinganiso Sokuguqula = Ukujika Kwekhoyili Eyinhloko ÷ Ukujika Kwekhoyili Yesibili

 

Isibonelo: Uma i-transformer inamajika ayi-1,000 kukhoyili yayo eyinhloko kanye namajika angu-2,000 kukhoyili yayo yesibili, isilinganiso se-Transformer singu-1:2.

 

 

2. Ukubala Isilinganiso Sokuguqulwa ngama-Voltage Okufaka Nokukhipha:

 

Ifomula: Isilinganiso Se-Voltage = I-Voltage Eyinhloko ÷ I-Voltage Yesibili

 

Isibonelo: Uma i-transformer ine-voltage eyinhloko engu-220V kanye ne-voltage yesibili engu-110 V, isilinganiso se-voltage singu-2:1.

 

 

3. Ukubala Isilinganiso Sokuguqulwa Ngamandla Alinganiswe Ngokuguqulwa:

 

Ifomula: Isilinganiso soguquko=isibonakaliso sempande (umthamo olinganisiwe we-transformer x i-voltage yokufaka) ÷ i-voltage yokuphuma

 

Isibonelo: Uma i-transformer inamandla alinganiselwe angu-1,000 VA, i-voltage yokufaka engu-220 V, kanye ne-voltage yokuphuma engu-110 V, isilinganiso sokuguqulwa singu-2:1.

 

 

4. Ubudlelwano Phakathi Kwesilinganiso Sokujika kanye Nesilinganiso Se-Voltage

 

Amandla e-electromotive abangelwa yi-induced (EMF) ekugoqeni okuyinhloko (ohlangothini lokufaka) kanye nasekugoqeni kwesibili (ohlangothini lokukhipha) kwe-transformer alingana ngqo nenani lamajika ekugoqeni ngakunye. Ngakho-ke, isilinganiso se-voltage yokufaka ohlangothini oluyinhloko ne-voltage yokukhipha ohlangothini lwesibili silingana nesilinganiso samajika.

 

 

Uma kubalwa isilinganiso se-transformer, indlela efanele ingakhethwa ngokusekelwe kumapharamitha angempela e-transformer kanye nezimo.

 

Umthelela Wesilinganiso Sokuguqula Kuhlelo Lwamandla

 

 

1. Ukuqina Kwe-Voltage

 

Izinguquko kusilinganiso se-transformer zithinta ngqo ukuzinza kwe-voltage kwezinhlelo zamandla. Ngokukhethekile, isilinganiso sokuguqulwa esikhulayo siholela ekukhuphukeni kwe-voltage, kuyilapho isilinganiso esinciphile sibangela ukwehla kwe-voltage. Emisebenzini engokoqobo, ubukhulu bokuhlukahluka kwesilinganiso sokuguqulwa kumele bulawulwe ngokunembile ukuqinisekisa ukuthi ukuzinza kwe-voltage yesistimu kuhlala ngaphakathi kwemingcele eyamukelekayo.

 

 

2. Amandla Okudlulisa Amandla

 

Ukulungiswa kwesilinganiso se-transformer nakho kuthinta ikhono lokudlulisa amandla lesistimu. Isilinganiso sokuguqulwa esincishisiwe sinciphisa ugesi olinganiselwe we-transformer, okungase kwehlise umthamo womthwalo. Ngesikhathi esifanayo, amandla asabelayo ohlelweni athintwa ukuguqulwa kwesilinganiso. Ngenxa yalokho, imiphumela kumthamo wokudlulisa amandla kumele ihlolwe kahle ngesikhathi sokulungiswa kwesilinganiso.

 

 

3. Izingozi Zokuphepha

 

Ama-transformer ezinhlelweni zamandla ngokuvamile asebenzisa ama-core acwebezelayo ekwakheni ama-winding. Ukushintsha isilinganiso sokuguqulwa kudinga ukulungisa i-total magnetic flux ye-core. Ukusebenza kabi kobuchwepheshe kungabangela i-core flux ngokweqile, okudala izingozi zokuphepha njengokwehluleka kokufakwa kwe-insulation noma ukushisa ngokweqile kwemishini.

 

 

4. Imithelela Ezimweni Ezikhethekile Zokusebenza

 

Ezimweni ezithile (isb., ukuhlolwa nokugcinwa kwesistimu yamandla ngesikhathi sokwakhiwa), ukushintsha isilinganiso se-transformer kungadingeka ukuze kuthuthukiswe ukusebenza kwesistimu. Kodwa-ke, izinguquko ezinjalo zidinga ukuhlolwa okujulile kwemiphumela yazo ekuzinzeni nasekuphepheni kokusebenza kwesistimu yamandla iyonke.

 

 

Isilinganiso sokuguqulwa kumele sikhethwe ngokuhambisana namazinga kagesi wegridi, amaphethini okushintshashintsha komthwalo, kanye nezidingo zokusebenza kwezomnotho. Njengepharamitha ebalulekile ekwakhiweni kwesistimu yamandla, ukusebenza, kanye nokuvikelwa, ukumiswa okunengqondo kwesilinganiso se-transformer kuthinta ngqo ukuzinza kwamandla kagesi, ukwenziwa ngcono kokusebenza kahle kwamandla, kanye nokuphepha kwemishini. Ukulungiswa kwesilinganiso sokuguqulwa kudinga ukucatshangelwa okuphelele kwe-topology yegridi, izici zomthwalo, kanye nemikhawulo yokuthunyelwa kwezomnotho ukuze kuncishiswe izingozi ezingaba khona njengemisinga ejikelezayo kanye nokuwa kwamandla kagesi.
