Txhaum thiab txij nkawm ntawm high voltage squage tawb three-phase asynchronous engine

Txhaum thiab txij nkawm ntawm high voltage squage tawb three-phase asynchronous engine

Ib lub tshuab hluav taws xob siab yog lub cav uas ua haujlwm ntawm qhov hluav taws xob 50 Hz, ib qho tsis muaj zog ntawm 3 kV, 6 kV, thiab 10 kV AC three-phase voltage. Nws muaj ntau txoj kev cais tawm tswv yim rau cov tshuab hluav taws xob muaj zog, xws li me me thiab nruab nrab, qhov loj thiab loj tshaj loj; los ntawm A, E, B, F, H, thiab C motors nyob rau hauv cov nqe lus ntawm rwb thaiv tsev; General-purpose high-voltage motors thiab high-voltage motors nrog tshwj xeeb cov qauv thiab kev siv.

Lub cav yuav tsum tau piav qhia nyob rau hauv daim ntawv no yog lub ntsiab lus-qib high-pressure squirrel-tawb rau peb theem asynchronous engine.

Qhov high-voltage nas-pob zeb peb-theem asynchronous lub cev ua tau los ntawm cov hauv paus ntawm electromagnetic induction. Nyob rau hauv qhov kev txiav txim siab ntawm siab electromagnetic teb thiab nws tus kheej cov kev mob, sab nrauv ib puag ncig thiab kev khiav hauj lwm rau cov xwm txheej, lub cav yuav raug tsim tawm hauv ib lub sij hawm ntawm kev khiav hauj lwm. Ntau cov hluav taws xob thiab cov neeg kho tshuab tsis tiav.

1 high voltage motor feem ntau tsis

1.1 Lub cev muaj hlau thaiv tsis ua hauj lwm yog qhov tsawg, qhov rai thaiv hluav taws xob tsis ua hauj lwm thiab ua kom tsis muaj teeb meem

Vim lub voj ib puag ncig, lub rwb thaiv tsev ntawm lub cav yog cov ntxooj, thiab qhov raug thaiv tus nqi tsis muaj raws li cov cai ntawm cov cai; vim cov plua tshauv loj, cov khoom sib nqus zom zaws rau ntawm lub coil, ua rau tshwm ntsej muag drilling, ua rau lub rwb thaiv tsev ntawm qhov stator winding kom tawg mus rau hauv av; lub teeb meem ntawm lub cev muaj hlau yog nyob ntawm Lub chaw kub cua nyob sab nraum qab ntawm cov tub ntxhais hlau tub ntxhais thiab muaj hnub nyoog tom qab ua haujlwm ntev. Cov roj hmab thaiv ntawm cov hlau lead yog crispy, deteriorated thiab peeled tawm. Kev quab yuam sab nraud thiab cov neeg kho tshuab ua rau lub plab ua rau lub plhaub taum pauv mus rau lub cev los yog lub cev qoj hlau xoob, ua rau cov neeg pluag tsis zoo los yog tawg ntawm lub cev qia hlau thiab cov kab mob loj heev. .

1.2 Lub cev muaj zog stator slot wedge xoob, kawg banding txhaum tsis ua hauj lwm

Tus stator wedge ntawm lub cev yog xoob thiab qhov xaus ntawm qhov tsis khov tsis yog khi. Thaum lub tshuab pib lub zog thaum pib thiab khiav, lub kauj vab yog ib qho chaw txav chaw, thiab lub suab paj nruag electromagnetic ntawm lub cev loj, thiab muaj paug tshwm sim tshwm sim.

1.3 Rotor tsis ua haujlwm

Cov teebmeem ntawm thermal effect force, electromagnetic force thiab txhua yam centrifugal force tsim thaum lub sijhawm ua haujlwm thiab ua haujlwm dhau ntawm kev tsav ua lwm yam kev nyuaj siab, uas ua rau lub suab paj nruag luv luv ntawm lub taub hau squirrel-cage rotor mus rau welded rau lub vib voos weld, lub rotor tooj liab lub voos yog loosened nyob rau hauv lub zawj. Tus stator tam sim no viav yog loj, lub zog kev vibration yog mob hnyav, lub tshuab electromagnetic ntawm lub zog nce thiab qhov paug tshwm sim tshwm sim.

1.4 kev tsav tsheb tsis ua haujlwm

Cov kab no tsis tau muab ntsia thwj, qhov kev kam ua haujlwm dhau los yog qis heev, thiab cov roj tsis zoo ntxiv. Thaum lub sijhawm ua haujlwm, cov kabmob ua kom sov siab, qhov kub nce siab yog siab dhau lawm, qhov kev vibration loj, thiab lub suab ntawm cov kabmob yog txawv txav.
