Ukudibanisa imoto yesigaba esithathu

Kubunjineli bamandla kukho iindlela ezimbini ezilula zokudibanisa imoto yesigaba esithathu. Zihluke kakhulu phakathi kwazo, kwaye ukhetho lwabo luxhomekeke kwiimeko zokusebenza kunye nohlobo lwenjini.

Uhlobo lokuqala lusebenzisa uxhumano lwezithuthi ezintathu olubizwa ngokuthi "unxantathu". Kuquka ukujoyina i-stator windings kwiinkalo. Enyanisweni, ukuphela kokuqala kweemoto ukuqala ukuxhuma kunxulumene nesibini. Olu hlobo lwenxibelelwano luthatha ukuvela kwamanqanaba aphezulu okuqala kwaye ivumela injini ukuba inike amandla apheleleyo epaspoti.

Udidi lwesibini lwenxibelelwano lubizwa ngokuthi "inkwenkwezi". Xa uyisebenzisa, iiphelo ze-windings zixhunyiwe kunye, kwaye amandla atyiswa ekuqaleni kwawo. Olu xhotho lweemoto zesigaba esithathu luyakuncipha, kodwa injini ivelisa amandla angaphantsi kwesigxina kunokuba ixhunywe "ngxantathu".

Eyona ndlela ichanekileyo ukuxhunyezwa okudibeneyo. Isetyenziswe ikakhulu kwiinjinjini eziphezulu, kodwa iyafaneleka kwiimeko zasekhaya, kuba ikhusela injini ekungenakudinganiselwe okungaphezulu, kwaye ngexesha elifanayo linika amandla apheleleyo atshawayo kwipaspoti. Injini iqalisa ukusebenzisa uxhumano lweenkwenkwezi. Ngexesha elifanayo, ayiyi kuba nemithwalo enzima evela emanzini aphezulu. Emva kokuba iinguqulelo zifikelele kwixabiso lokutyunjwa, utshintsho oluya kutsho "unxantathu" luqhubeka, oluqhubeka lude luphele ekupheleni komsebenzi. Olu dlelwane lwemoto yesigaba esithathu luquka ukusetyenziswa kwexesha elide okanye inkwenkwezi ekhethekileyo.

Ngokwahlukileyo kubalulekile ukuba uqaphele ukuba ezininzi iinjini zichithe kakubi kumaconsi ombane okanye iisekethe ezifutshane. Ngoko ke, xa kuphuhliswa iiprojekthi zokudibanisa imoto yesithathu, ngokuqhelekileyo isiphaluka siquka i-fuse-links okanye iindlela ezikhuselekileyo zokukhusela.

Ngokuqhelekileyo, abantu abaninzi bajamelene nemeko apho kukho imoto yesigaba esithathu, kwaye inethiwekhi yombane inesigaba esisodwa kuphela. Kwiimeko ezinjalo, imoto yesigaba esithathu ixhunyiwe kwi-network-phase network usebenzisa i-capacitors. Baxhunyiwe kwi-terminal yokuphefumula ekhululekile kwaye baxhunyiwe kwinethiwekhi. Kufuneka kukhunjulwe ingqalelo ukuba amandla okuxhobisa ama-capacitor kufuneka ahluke ngokukhawuleza ngejinjini. Ngoko ke, zidibaniswe ngokufanayo komnye nomnye ngendlela, xa uguquliwe, zombini i-capacitors inethiwekhi, kwaye xa ufikelela kwisantya sokusebenza, isisombululo sesibini kufuneka sitshintshwe.

Ngoko ke, xa imoto yesigaba esithathu ixhunyiwe kwi-network-phase network, i-capacitor, isebenzayo rhoqo, ibizwa ngokuba yisebenzayo, kwaye leyo inqatshelwe ibizwa ngokuba yiyokuqala. Kule meko, umthamo wokuqalisa umbane kufuneka ube malunga nokuphindwe kathathu kwekhono lomsebenzi. I-capacitor yokuqala ixhunywe ngekhompini ehlukeneyo, egcinwa de iinjinisi zifikelela kwisantya sokubeka.

Kubalulekile ukuphawula ukuba ngale nxibane, injini ilahlekelwa ngaphezu kwe-60% yamandla ayo, kwaye ukuba idibaniswe isebenzisa "icebo" lecebo, ngoko ukulahleka okunjalo kunokunyuka ngesinye isiqingatha. Ngoko ke, kwiimeko ezinjalo kucetyiswa ukuba kusetyenziswe isicandelongo "soxantathu", ukwenzela ukuba ukulahlekelwa kwamandla kukuncinci.
