Inqaba yeCapacitor
Ukuze kuphuculwe ukuthembeka kunye nokukhuselwa kwenkqubo yokusebenza kwamandla, kuyimfuneko ukwenza uvavanyo lokunyuka kweqondo lokushisa kwiinguqu ezinkulu. Ngaphambi kokugqitywa okanye uxhulumaniso lwegridi ye-transformers enkulu, iimvavanyo zokunyuka kweqondo lokushisa zifunwa ngokubanzi kumenzi we-transformer okanye umatshini wokulungisa kunye nokuhlola inkqubo yamandla.
Ukuze kuphuculwe ukuthembeka kunye nokukhuselwa kwenkqubo yokusebenza kwamandla, kuyimfuneko ukwenza uvavanyo lokunyuka kweqondo lokushisa kwiinguqu ezinkulu. Ngaphambi kokugqitywa okanye uxhulumaniso lwegridi ye-transformers enkulu, iimvavanyo zokunyuka kweqondo lokushisa zifunwa ngokubanzi kumenzi we-transformer okanye umatshini wokulungisa kunye nokuhlola inkqubo yamandla. Ixabiso lokunyuka kweqondo lokushisa kwecandelo ngalinye le-transformer yenye yeempawu zeempawu ze-transformer, kwaye i-transformer iya kumelana novavanyo lokunyuka kweqondo lokushisa phantsi kweemeko ezichaziweyo. Injongo yovavanyo lokunyuka kweqondo lokushisa kukufumana ixabiso lokunyuka kweqondo lokushisa kwinqanaba ngalinye le-transformer kunye nokuqinisekisa idatha yoyilo lwe-transformer ukuqinisekisa ukuba ukunyuka kwayo kweqondo lokushisa kuhambelana nemida echazwe kwimigangatho efanelekileyo.
Indlela yesekethe emfutshane idla ngokusetyenziswa kuvavanyo lokunyuka kobushushu kwi-oyile enkulu entywiliselwe isiguquli. Indlela ye-short-circuit kumjikelezo omfutshane kwelinye icala le-transformer kunye nokubonelela ngamandla kwelinye icala. Isekethe yovavanyo iyafana ngokupheleleyo novavanyo lomthwalo [2]. Unikezelo lwamandla ovavanyo lunokufumaneka ngokuthe ngqo kwigridi yamandla okanye lubonelelwe ngeseti yayo yokuvavanya ijenereyitha. Ngenxa yokuba i-transformer evavanyiweyo inomthamo omkhulu, ikwadinga unikezelo lwamandla ovavanyo olukhulu. Ekubeni i-impedance ye-short-circuit ye-transformer ikakhulu i-reactance, i-transformer evavanyiweyo enomthamo omkhulu eneneni ngumthwalo omkhulu we-inductive, ngoko ke indlela yembuyekezo yebhanki ye-capacitor ingasetyenziswa xa kusenziwa uvavanyo lokunyuka kobushushu, oko kukuthi, i-capacitive reactive current of Ibhanki ye-capacitor isetyenziselwa ukubuyisela i-inductive reactive current ye-transformer evavanyiweyo, kunye nomthamo wokunikezelwa kwamandla okuvavanya kunokumiselwa ngokuhambelana nomthamo osebenzayo welahleko we-transformer evavanyiweyo. Oku kunciphisa kakhulu umthamo wonikezelo lwamandla ovavanyo olufunekayo kwaye lugcina utyalo-mali lweseti epheleleyo yezixhobo zovavanyo.
Umgaqo wesakhiwo osisiseko, umgaqo wolawulo lwesibini kunye nokufezekiswa kwayo kwembuyekezo ye-capacitor tower ye-transformer enkulu yovavanyo lokunyuka kobushushu. Inkqubo ithatha isilawuli esicwangcisiweyo samva nje se-PLC kunye nesixhumi se-pneumatic, esingenako ukuguquguquka kunye nokuthembeka nje ukulungelelanisa inqanaba lombane kunye nomthamo wembuyekezo yembuyekezo ye-capacitor tower, kodwa ineempawu zokhuseleko oluphezulu, ubukrelekrele obuphezulu kunye nokusebenza ngokulula. Inkqubo inokuhlangabezana neemfuno zovavanyo lokunyuka kobushushu kwiinguqu ezinkulu ezinamaqondo ombane ahlukeneyo kunye namandla.
INHLOKO-UHLOBO-1
I-voltage ephezulu ehambelana ne-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.
