Kutheni kusetyenziswa ukhuseleko lokwahluka kwiimoto ezinkulu ezine-voltage ephezulu?

Xa kuthelekiswa nezinto ezincinci nezincinciiimoto eziphakathi,iimoto ezine-voltage ephezuluzibiza kakhulu, kwaye iimeko zokusetyenziswa kwazo zibalulekile kwaye zikhethekile. Nokuba kukulahlwa komzimba wemoto emva kwempazamo okanye ezinye iingxaki ezivela kwimpazamo, inokuba yingozi kakhulu kunokuba sinokuyicinga. Ngenxa yesi sizathu, izixhobo zokukhusela umahluko zisetyenziselwa iimoto ezine-voltage ephezulu ezisetyenziswa kwiimeko ezithile ezikhethekileyo, injongo yazo kukufumanisa iingxaki ngexesha elifanelekileyo nangokufanelekileyo kunye nokuthintela ukonakala ngakumbi kweengxaki.
Ukhuselo lokwahluka yindlela yokukhusela esebenza kakuhle kakhulu ekusebenzeni ngokukhuselekileyo kwezixhobo zombane. Isebenzisa iimpawu zokuqalisa izenzo zokhuseleko ngomahluko wevektha phakathi komsinga wokufaka kunye nomsinga wokuphuma weizixhobo zombane, nto leyo eyenza ukuba naluphi na uthungelwano lombane olunezikhewu ezimbini, ijenereyitha, imotha, itransformer kunye nezinye izixhobo zombane zibe nezicelo zakudala kakhulu.

Ukhuseleko lokwahluka lusetyenziswa kakhulu kwiimoto ezinkulu ezine-voltage ephezulu. Umzekelo, iimoto ezine-voltage ephezulu ezisetyenziswa kwizixhobo zamandla eziphambili kunye nezixhobo zokungenisa umoya eziphambili kufuneka zixhotyiswe ngezixhobo zokukhusela ukwahluka ukuqinisekisa ukusebenza ngokukhuselekileyo nangokuthembekileyo kwenkqubo kunye nokuphepha ilahleko ezinkulu kwezoqoqosho kunye neengozi zokhuseleko ezibangelwa kukuvalwa okungalindelekanga.
Ii-stator windings zeemoto ezinkulu ezine-high-voltage zihlala zisebenzisa uqhagamshelo lweenkwenkwezi, kunye nee-output terminals ezintathu ngokungagqibekanga. Xa kuqaliswa ukhuselo lomahluko, imoto kufuneka ibe nee-output terminals ezi-6. Isixhobo sokukhusela umahluko esisetyenziswa kwimoto sisebenza ngolu hlobo lulandelayo: fumana i-start and end currents yemoto, kwaye uthelekise umahluko wesigaba kunye ne-amplitude phakathi kwe-start and end currents. Phantsi kweemeko eziqhelekileyo, umahluko kwi-amplitude kunye nesigaba phakathi kwe-start and end currents yi-zero, oko kukuthi, i-current egeleza kwimoto ilingana ne-current egeleza iphuma kwimoto; xa kwenzeka i-short circuit fault efana ne-phase-to-phase, turn-to-turn okanye to ground ngaphakathi kwimoto, i-differential current iveliswa phakathi kwezi zimbini kwaye ifikelela kwixabiso elithile, umsebenzi wokukhusela uyavuselelwa.
