I-6-220kV isiguquli seHV esintywiliselwe ngeoli

Isiguquli samandla

Isiguquli samandla sisixhobo sombane esingaguqukiyo esisetyenziselwa ukuguqula ixabiso elithile lombane we-AC (okhoyo) kwelinye okanye amaxabiso ahlukeneyo ombane ombane (okwangoku) anezandi ezifanayo.

Isixhobo esimiyo esinamajiko-jiko amabini okanye ngaphezulu, ukuze kudluliswe amandla ombane, siguqula amandla ombane e-AC kunye nokukhoyo kwenkqubo enye kumbane kunye nokukhoyo kwenye inkqubo ngokufakelwa kombane ngesantya esifanayo. Ngokuqhelekileyo, amaxabiso ale misinga kunye ne-voltages ahlukile.

Isiguquli sisixhobo sombane esingaguqukiyo esisetyenziselwa ukuguqula amandla ombane e-AC kunye nawangoku kunye nokuhambisa amandla ombane e-AC. Ifezekisa ukuhanjiswa kwamandla ombane ngokusekelwe kumgaqo wokungeniswa kwe-electromagnetic. Abaguquli banokuhlulwa babe ngabaguquli bamandla, abaguquli bokuvavanya, abaguquli bezixhobo, kunye nabaguquli benjongo ekhethekileyo ngokusekelwe ekusebenziseni kwabo: abaguquli bamandla zixhobo eziyimfuneko zokuhanjiswa kwamandla kunye nokusabalalisa, kunye nokuhanjiswa komsebenzisi wamandla; Izixhobo zokuqhuba uvavanyo lwe-voltage standstand (boost) kwisixhobo sombane kusetyenziswa ii-test transformers; Iziguquli zesixhobo zisetyenziselwa ukulinganisa umbane kunye nokukhuselwa kwe-relay kwiinkqubo zokusabalalisa (PT, CT); Iinguqu zenjongo ezikhethekileyo ziquka ukunyibilikisa iziguquli zesithando somlilo, iziguquli ze-welding, iziguquli ze-electrolytic rectifier, ii-voltage ezincinci ezilawulayo, njl.

Isiguquli samandla sisixhobo sombane esingaguqukiyo esisetyenziselwa ukuguqula ixabiso elithile lombane we-AC (okhoyo) kwelinye okanye amaxabiso ahlukeneyo ombane ombane (okwangoku) anezandi ezifanayo. Xa i-alternating current isetyenziswa kwi-primary winding, i-alternating magnetic flux yenziwa. Ukuguquguquka kwamagnetic okutshintshisanayo kubangelwa kumoya ojikelezayo wesibini ngesiphumo sokuqhuba kazibuthe kumbindi wentsimbi, okukhokelela kumandla ombane otshintshanayo. Ukuphakama kwamandla e-electromotive okwesibini kunxulumene nenani lokujika kwi-windings yokuqala kunye neyesibini, oko kukuthi, i-voltage ihambelana ngokuthe ngqo nenani lokujika. Umsebenzi oyintloko kukudlulisa amandla ombane, ngoko ke, umthamo olinganisiweyo yipharamitha yayo ephambili. Umthamo olinganisiweyo lixabiso eliqhelekileyo elisetyenziselwa ukumela amandla, obonisa ubungakanani bamandla ombane adlulisiweyo, abonakaliswe kwi-kVA okanye i-MVA. Xa i-voltage elinganisiweyo isetyenziswe kwi-transformer, isetyenziselwa ukumisela i-current rated current engadluli kumda wokunyuka kweqondo lokushisa phantsi kweemeko ezichaziweyo. Esona siguquli samandla sisebenza ngamandla sisiguquli sentsimbi esisiseko se-amorphous, enenzuzo enkulu yokuba nexabiso eliphantsi kakhulu elingenamthwalo. Ingaba ixabiso lokugqibela elingalahlekiyo lingaqinisekiswa ngumba ongundoqo oza kuqwalaselwa kuyo yonke inkqubo yoyilo. Xa ulungiselela ukwakhiwa kwemveliso, ngaphezu kokuqwalasela ukuba i-amorphous alloy iron core ngokwayo ayixhomekeke kumandla angaphandle, kuyafuneka ukuba ukhethe ngokuchanekileyo nangengqiqo imilinganiselo yeempawu ze-amorphous alloy ngexesha lokubala.

INHLOKO-UHLOBO-1

I-voltage ephezulu ye-capacitor parallel capacitor ilungele uqhagamshelo oluhambelanayo kwiinkqubo zamandla ze-AC kunye ne-frequency frequency (50Hz okanye 60Hz) ye-1kV nangaphezulu. Zisetyenziselwa ukubuyisela amandla asebenzayo, ukuphucula amandla ombane, ukuphucula umgangatho wamandla ombane, ukunciphisa ilahleko yomgca, kunye nokusetyenziswa ngokupheleleyo kokuveliswa kwamandla kunye nezixhobo zokubonelela.
