Yini imiphelo yokuqunga kwezilungelelo eziqoqo kwamandla?

Ukungabi noma fusho kwezinhlobo zintathu zokusetshenziswa kwamandla kwenza iziphumo eziningi ezingavulekile, kubandakanya ukongeza kwamandla ekugcineni kwezindlela, ukongeza kwamandla ekugcineni kwezitrafomethi zokwahlisa, ukuncipiswa kwezindlela zokuhlisa kwamandla kwezitrafomethi, ukudala kwe-zero-sequence current kwezitrafomethi, ukulahleka kwezimali zokusebenza ngendlela elungile, nokuncipiswa kwe-efficiency yezimotela. Kangakanani ukuthi ukungabi noma fusho kwezinhlobo zintathu zokusetshenziswa kwamandla kuthintelwe? Isigaba esilandelayo seNantong Zhifeng Electric Technology Co., Ltd. sikhombisa ngokuhlelwa iziphumo zokungabi noma fusho kwezinhlobo zintathu nezindlela zokuthuthukisa.

Iziphumo zokungabi noma fusho kwezinhlobo zintathu zokusetshenziswa kwamandla:

1. Ukongeza kwamandla ekugcineni kwezindlela

Kunethikholethi yamathrii-feyisi nengxenyana ezingane, xa ikhurrenti iphumelela kuzwire yesikholethi, iphumelela kwezinhloso zokusebenza kuyakhiwa ngokuthi kunezimpedansi, futhi le kuyakhiwa phezu kwekhurrenti. Xa inxenye yaphansi yekhahlelwe yasiphiwe ngenkqubo yamathrii-feyisi nengxenyana ezingane, ukungcono kwezilayini ezingxenyana kuyakhiwa ukungcono kwezilayini zokusebenza. Ngokwesibonelo esingenakulwandle, ikhurrenti iphumelela kuzwire zenxenyana. Lokhu kuyakhiwa kwezinhloso ezilayini noma kwezinhloso zenxenyana, ngakho kuyakhula kwezinhloso zizonke kuzwire zekhahlelwe.

2. Kukhanya kwezinhloso zokusebenza kwezitrafomethi zokwahlisa

Isitrafomethi sokwahlisa yisiphequluli esikhulu kuzinhloso zokusebenza kwenxenye yaphansi yekhahlelwe. Xa isebenza ngaphansi kwezimo zokungcono kwezilayini zokusebenza, kuyakhiwa ukhanya kwezinhloso zokusebenza kwisekhahlelwe ngokuthi izinhloso zokusebenza kwisekhahlelwe ziyathinta ngokulinganisa kwezimo zokungcono.

3. Ukuncipha Kwesayizi Phakathi Kwemikhawulo

Kwesivakalisi esivumelana nezinhlobo zokulayisha, izinhlobo zokulayishwa kwesivakalisi kubasekile kakhulu kuzindlela zokusebenza ngokulinganile, nezinhlobo zokulayisha efanayo kanye nezindlela zokulingana nezinye izinhlobo. Isiphumo esikhulu esikwaziwa yisivakalisi kubukekelwe ngokulingana nezinhlobo. Uma isivakalisi sebenza ngaphansi kwezindlela ezingalinganiyo, izinhlobo ezimvimbi zinezindlela ezingaphezulu, okungenzeka ukuncipha okuphumelelwa yisivakalisi. Ubuncinci bokuncipha kubukekela ngokulingana nezindlela ezingalinganiyo. Ukuwukhulu kwezingalingano, ukuncipha kwezinhlobo kungaphezulu. Ngakho, uma kusebenzwa ngaphansi kwezindlela ezingalinganiyo, amandla wokuphumla yisivakalisi akwazi ukufinyelela kwezindlela, amandla wokugcina akwazi ukuncipha, kanye nezindlela zokusebenza ngaphandle kwezinga elilinganileyo. Uma isivakalisi sebenza ngaphandle kwezinga elilinganileyo, kungenzeka kakhulu ukuthi kuthinte isivakalisi, okungase kuthinte isivakalisi ngokuphezulu.

ukuhlanjwa kwe-zero-sequence current ngotransformer yedistribusi

Xa itrafomha yokuvela isebenza ngemimo yokuqalwa kwezingxenye eziqulatha, ikhurrenti yokuqala engaphezu kwezingxenye eziqulatha iphumelelwa. Lokhu ikhurrenti kuyindlela enguququke kweqembu lokusebenza kwezingxenye eziqulatha; ngokuthandwayo kweqembu, ngokuthandwayo ikhurrenti yokuqala engaphezu kwezingxenye eziqulatha. Uma ikhurrenti yokuqala engaphezu kwezingxenye eziqulatha ikhona kumaphoyisa itrafomha yokuvela, ikhurrenti yokuqala engaphezu kwezingxenye eziqulatha izokweqwa kumakoti kwayo. (Akukho ikhurrenti yokuqala engaphezu kwezingxenye eziqulatha ekabanjinini eliphezulu.) Lokhu kuthinte ukuthi ikhurrenti yokuqala engaphezu kwezingxenye eziqulatha iyase kwezindawo eziphakeme kwayo nezinto zokuvumela izinkulungwane. Ngoba ikhurrenti yokuqala engaphezu kwezingxenye eziqulatha ingaphansi kwezingxenye eziyinkulu, ikhurrenti yokuqala engaphezu kwezingxenye eziqulatha iyase kwezindawo eziphakeme kwayo nezinto zokuvumela izinkulungwane. Ngokuthi ikhurrenti yokuqala engaphezu kwezingxenye eziqulatha iyase kwezindawo eziphakeme kwayo nezinto zokuvumela izinkulungwane, ikhurrenti yokuqala engaphezu kwezingxenye eziqulatha iyase kwezindawo eziphakeme kwayo nezinto zokuvumela izinkulungwane. Izingxenye ezinhlelweyo zitrafomha yokuvela ziyase kweqembu lokusebenza kwezingxenye eziqulatha, lapho kuthinta ukuthi itrafomha iyase kweqembu lokusebenza kwezingxenye eziqulatha. Ngokudla, ukuthi ikhurrenti yokuqala engaphezu kwezingxenye eziqulatha ikhona kuthinta ukuthi itrafomha yokuvela iyase kweqembu lokusebenza kwezingxenye eziqulatha.

5. Isiphikiswano kwemisebenzi emiselweni yokusebenza kwamagadetsi aphakeme

Ithransifomha yokuvela yadizaynwe ngokwesivinini sokusebenza kweziload ezingaphandle kwezinye, nezindlela zokusebenza, izivivinyo nezimpilili zokungenela kwezinye zingaphandle kwezinye. Xa ithransifomha yokuvela isebenza ngokwesivinini sokusebenza kweziload ezingaphandle kwezinye, amandla wokusebenza kwezinye ayalingana, futhi izindlela zokulahla kwezinye kwezinye zingaphandle kwezinye; ngakho ke amandla wokusebenza kwezinye kwezithrhisifomha ayalingana. Uma ithransifomha yokuvela isebenza ngokwesivinini sokusebenza kweziload ezingaphandle kwezinye, amandla wokusebenza kwezinye kwezinye kuzo zingalingana, futhi izindlela zokulahla kwezinye kwezithrhisifomha kuzo zingaphandle kwezinye, okungenzeka ukuthi kubaluleke kweziload ezingaphandle kwezinye kwezithrhisifomha.

Kwesikhashana, xa isithuthi soludzindlela sisebenza ngekutshe kanjani kweemoto zokusebenza, iindlela zokusebenza zasekhanda zineempawu ezahlukene, okwenza ukuba kune ntla yemali ebuya kwiindawo zokugcinwa. Oku kwenza ukuba kube khona ukwehluka kwezindlela zokugcinwa, okwenza ukuba kwehlukane izindlela zokusebenza. Isindlela yeemoto ephakeme iphantsula, ngelixa isindlela ephantsula iphantsula. Ukunikezela amandla ngekutshe kanjani kweemoto zokusebenza kungenxa yokwenza ukuba izinto zokusebenza zibe yimali, ngelixa izinto zokusebenza zibe yimali kune ndlela yemoto ephantsula. Ngoko, ukusebenzisa iindlela zokusebenza zasekhanda zineempawu ezahlukene kungenxa yokwenza ukuba kube khona ingxenye yemali yezinto zokusebenza.

6. Ukuncipha kwezinhlanzelo zemali zemoto

Lapho ithransifomha yokuvela iphepha ngemoto yesithathu enezimbali, kubangela ukungenaniswa kwemoto yesithathu kumandla wokukhishwa. Ngoba umandla ongenanayo uyinqanaba le-positive-sequence, le-negative-sequence, nosilinda le-zero-sequence, lapho lemandla alandelayo athathwa kumotola yemali, le-negative-sequence ikhiqiza ummandla womkhonto ophindaphinda okuphambene no odaliwe ngu-positive-sequence, wokwenza umehhito wokulinda. Kodwa, ngoba umkhonto wase-positive-sequence uphakeme kakhulu kunase-negative-sequence, umotola yemali isabelapha emhlabeni wase-positive-sequence. Ngokulinda okuthiwa kumkhonto we-negative-sequence, amandla womotola yemali ayiphelela ukuba yinkimbinkimbi, okubangela ukuncipiswa kwehlekisa lemali. Ngokufanayo, ukuphakama kwezulu nokulahleka kwezinhlobo zemali kancipisa ngokuningi kwezimbali zemoto yesithathu. Ngakho, ukusebenzisa umotola yemali ngenkimbinkimbi yezimbali zemoto yesithathu kungcono kakhulu.
