Imowudi yokuqalisa
Imowudi yokuqala yenqanaba lesithathu le-asynchronous motor
1, ukuqala ngqo. Nangona kunjalo, xa i-motor ye-asynchronous yesigaba sesithathu iqala ngokuthe ngqo, i-current inokufikelela kumaxesha angama-6-7 i-current rated current, enempembelelo enkulu kwigridi yamandla, ngakumbi i-motor-power-power.
I-2, ukuqala kombane ocuthiweyo. Imbabala isiqalo ikakhulu ibandakanya eshushu autoot buck isiqalo kunye star unxantathu buck isiqalo.
Ukuqala kwe-autobuck eshushu kuthetha ukuba i-motor voltage iyancitshiswa kwaye i-current current iyancipha ngexesha elifanayo xa i-autotransformer iqaliswa. Ngokuqhelekileyo iyancipha ukuya malunga ne-55% -75% yombane olinganisiweyo. Inzuzo kukuba i-voltage yokuqala inokutshintshwa ngokulula ngokutshintsha inani leempompo ze-autotransformer. Ukungalungi yimfuneko yokusebenzisa i-autotransformer, ixabiso likhulu.
Unxantathu weNkwenkwezi inyathelo-ezantsi ukuqala ubhekisa kwindlela yokutshintsha umbane wokuqalisa ngokuguqula imowudi yoqhagamshelo lwemoto, ukuze kuncitshiswe isiqalo sangoku, esinokusetyenziswa kuphela kwimowudi yoqhagamshelo eqhelekileyo yoqhagamshelo lonxantathu lwenjini. Xa uqalwa, indlela yokudlulisa i-motor isetyenziselwa ukwenza imo ye-motor wiring efana neenkwenkwezi, ngeli xesha, i-voltage yesigaba ngasinye se-motor iyancitshiswa ukuya kwisinye kwisithathu sophawu lwengcambu, isantya semoto sifikelela malunga nama-80 ekhulwini. isantya esilinganiselweyo, kunye ne-relay yolawulo itshintsha imo ye-wiring ye-motor kunxantathu, kwaye i-motor iqala ukusebenza ngokuqhelekileyo. Inzuzo kukuba inokugcina i-autotransformer, ukunciphisa iindleko, kwaye indlela yocingo ilula kwaye ukuthembeka kukhulu. Ukungalungi kukuba umlinganiselo wokuqalisa i-voltage awukwazi ukutshintshwa, kwaye i-motor ayikwazi ukusetyenziswa kwi-star connection.
I-3, ukuqala kwe-resistor frequency. Ukuqala kokuxhathisa okubuthathaka kuthetha ukuba ukuxhathisa okunovakalelo rhoqo kuqhagamshelwe kuthotho kwisekethe ephambili xa kuqalwa i-motor, ngaloo ndlela kuncitshiswa isiqalo sangoku. Isichasi esinovakalelo rhoqo sinokutshintsha isiqalo sangoku ngokutyibilikayo kwaye sinempembelelo encinci kwigridi yamandla, ke yeyona ndlela ilungileyo yokuqalisa. Nangona kunjalo, i-resistors-sensitive-sensitive-high-power-frequency-sensitive resistors ikwimo yee-inductors, ngoko ke baya kuvelisa i-electromagnetic eddy yangoku esetyenziswayo, eya kunciphisa amandla ombane wegridi.
