Tsheb generator ntaus ntawv thiab lub hauv paus ntsiab lus ntawm kev ua haujlwm
Lub tshuab hluav taws xob yog qhov tseem ceeb ntawm cov cuab yeej ntawm txhua lub tsheb. Lub luag haujlwm tseem ceeb ntawm chav tsev no yog kev tsim hluav taws xob los muab nws nrog tag nrho cov kab ke ntawm lub tsheb thiab rov them lub roj teeb. Lub zog rotational ntawm lub crankshaft yog hloov mus rau hauv hluav taws xob.
Lub tshuab hluav taws xob txuas nrog lub crankshaft siv txoj siv sia siv - lub tshuab hluav taws xob siv. Nws yog muab tso rau ntawm lub crankshaft pulley thiab ntawm lub tshuab hluav taws xob pulley, thiab sai li sai tau thaum lub cav pib thiab cov pistons pib txav, qhov kev txav no tau pauv mus rau lub tshuab hluav taws xob rub thiab nws pib tsim hluav taws xob.
Tam sim no generated li cas? Txhua yam yog yooj yim heev, qhov tseem ceeb ntawm lub tshuab hluav taws xob yog lub stator thiab lub rotor - lub rotor rotates, lub stator yog ib feem ruaj khov rau lub puab casing ntawm lub tshuab hluav taws xob. Lub rotor tseem hu ua lub tshuab hluav taws xob armature, nws muaj cov ncej uas nkag mus rau lub tshuab hluav taws xob npog thiab txuas rau nws nrog cov kabmob, yog li ntawd cov ncej tsis overheat thaum lub sijhawm tig. Lub tshuab hluav taws xob ncej bearing tsis dhau lub sijhawm, thiab qhov no yog qhov tsis ua haujlwm loj, nws yuav tsum tau hloov raws sijhawm, txwv tsis pub lub tshuab hluav taws xob yuav tsum tau hloov tag nrho.
Ib los yog ob lub impellers muab tso rau ntawm lub rotor ncej, ntawm uas muaj ib tug excitation winding. Lub stator kuj muaj ib lub voj voog thiab hlau daim hlau - lub stator core. Cov cuab yeej ntawm cov ntsiab lus no yuav txawv, tab sis zoo li lub rotor yuav zoo li lub tog raj kheej me me tso rau ntawm cov menyuam; nyob rau hauv nws cov hlau phaj muaj ob peb coils nrog winding.
Thaum koj tig tus yuam sij hauv qhov hluav taws xob hloov ib nrab tig, qhov hluav taws xob yog siv rau lub rotor winding, nws raug xa mus rau lub rotor los ntawm lub tshuab hluav taws xob txhuam thiab cov ntiv tes xoo - cov hlau me me ntawm lub rotor ncej.
Qhov tshwm sim yog magnetic teb. Thaum kev sib hloov ntawm lub crankshaft pib xa mus rau lub rotor, ib qho kev hloov hluav taws xob tshwm nyob rau hauv stator winding.
Qhov voltage tsis tas li, nws qhov amplitude hloov pauv tas li, yog li nws yuav tsum tau sib npaug raws li qhov xav tau. Qhov no yog ua tiav siv lub tshuab rectifier - ob peb lub diodes uas txuas nrog stator winding. Lub luag haujlwm tseem ceeb yog ua los ntawm tus tswj hwm qhov hluav taws xob, nws txoj haujlwm yog tswj hwm qhov hluav taws xob ntawm qhov tsis tu ncua, tab sis yog tias nws pib nce, ces ib feem ntawm nws tau xa rov qab mus rau lub winding.
Cov tshuab hluav taws xob niaj hnub siv cov kab hluav taws xob sib txuas ua kom cov qib voltage tsis tu ncua nyob rau hauv txhua yam mob. Tsis tas li ntawd, cov kev cai yooj yim rau lub tshuab hluav taws xob teeb kuj tseem siv tau:
- tswj kev ua haujlwm ruaj khov ntawm txhua lub tshuab;
- roj teeb them txawm nyob rau hauv qis ceev;
- tswj qhov hluav taws xob nyob rau hauv qhov xav tau qib.
Ntawd yog, peb pom tias txawm hais tias lub tswv yim tiam tam sim no nws tus kheej tsis tau hloov pauv - lub hauv paus ntsiab lus ntawm electromagnetic induction yog siv - tab sis cov kev xav tau rau kev ua tau zoo tam sim no tau nce los tswj kev ua haujlwm ruaj khov ntawm on-board network thiab cov neeg siv hluav taws xob ntau. Qhov no tau ua tiav los ntawm kev siv cov conductors tshiab, diodes, rectifier units, thiab kev txhim kho cov txheej txheem txuas ntxiv.
