Imo yokuqalisa yesiqalo
Imo yokuqala yemoto engenazintlu ezintathu
1, ukuqala ngokuthe ngqo. Nangona kunjalo, xa i-motor yesigaba esi-3 i-asynchronous iqala ngokuthe ngqo, i-current inokufikelela amaxesha ama-6-7 kumbane olinganisiweyo, nto leyo enefuthe elikhulu kwi-power grid, ingakumbi i-motor enamandla aphezulu.
2, ukuqala kwe-voltage encitshisiweyo. Ukuqala kwe-buck kuquka ikakhulu i-hot autoroot buck start kunye ne-star triangle buck start.
Ukuqala kwe-autobuck eshushu kuthetha ukuba i-voltage yemoto iyancipha kwaye umsinga wokuqalisa uyancipha ngexesha elinye xa i-autotransformer iqaliswa. Ngokuqhelekileyo incitshiswa ukuya kuthi ga kwi-55%-75% ye-voltage elinganisiweyo. Inzuzo kukuba i-voltage yokuqala inokutshintshwa ngokulula ngokutshintsha inani lee-taps ze-autotransformer. Ingxaki kukusebenzisa i-autotransformer, ixabiso likhulu.
Ukuqala kwe-star triangle step-down kubhekisa kwindlela yokutshintsha i-start voltage ngokutshintsha i-motor, ukuze kuncitshiswe i-start current, enokusetyenziswa kuphela kwi-common eqhelekileyo yoqhagamshelo lwe-triangle ye-motor. Xa uqalisa, indlela ye-relay isetyenziselwa ukwenza i-motor wiring mode ibe yi-star, ngeli xesha, i-voltage yesigaba ngasinye se-motor incitshiswa ukuya kwi-1/3 ye-original root sign, i-motor speed ifikelela malunga ne-80% ye-rated speed, kwaye i-control relay itshintsha i-motor wiring mode ibe yi-triangle, kwaye i-motor iqala ukusebenza ngokuqhelekileyo. Inzuzo kukuba inokonga i-autotransformer, inciphise iindleko, kwaye indlela ye-wiring ilula kwaye ukuthembeka kukhulu. Ingxaki kukuba umlinganiselo we-start voltage awunakutshintshwa, kwaye i-motor ayinakusetyenziswa kwi-star connection.
3, ukuqala kwesithinteli semvamisa. Ukuqala kokuchasana nemvamisa kuthetha ukuba ukuchasana nemvamisa kuqhagamshelwe kuthotho kwisekethe ephambili xa injini iqaliswa, ngaloo ndlela kunciphisa umsinga wokuqalisa. Isithinteli semvamisa sinokutshintsha umsinga wokuqalisa kakuhle kwaye sibe nefuthe elincinci kwigridi yamandla, ngoko ke yindlela efanelekileyo yokuqalisa. Nangona kunjalo, ii-resistor zemvamisa ezinamandla aphezulu zikwimo yee-inductors, ngoko ke ziya kuvelisa umsinga omkhulu we-electromagnetic eddy osetyenziswayo, oya kunciphisa amandla egridi.
I-Zhuo Meng Shanghai Auto Co., Ltd. izimisele ukuthengisa iinxalenye zeemoto ze-MG&MAUXS kwaye wamkelekile ukuzithenga.
