Kho thiab kho ntawm nruab nrab zaus fais fab mov system

Qhov nruab nrab zaus fais fab mov muab faib ua peb ntu: cov dej system, hydraulic system thiab hluav taws xob system. Lub hom phiaj yog nyob rau hauv kev saib xyuas ntawm lub tshuab hluav taws xob.

Kev xyaum tau ua pov thawj tias feem ntau ntawm qhov tsis raug ntawm qhov nruab nrab zaus fais fab mov yog ncaj qha cuam tshuam rau txoj kev dej. Yog li ntawd, txoj kev hauv dej yuav tsum muaj cov dej zoo, dej siab, dej kub, thiab dej ntws yuav tsum ua kom tau raws li cov khoom siv.

Kev saib xyuas hluav taws xob: Lub tshuab hluav taws xob yuav tsum tau hloov kho tsis tu ncua. Vim hais tias qhov tseem ceeb ntawm kev sib txuas yog ib qho yooj yim los tsim kom muaj cua sov, uas tuaj yeem ua rau ignition (tshwj xeeb tshaj yog cov kab nrog cov kab hluav taws xob nkag siab tshaj 660V los yog cov rectifier feem txais yuav series boost hom), ntau yam tsis paub meej tshwm sim.

Raws li ib txwm muaj, qhov txhaum ntawm qhov nruab nrab zaus fais fab mov tuaj yeem muab faib ua ob pawg: tsis tuaj yeem pib thiab tsis tuaj yeem ua haujlwm li qub tom qab pib. Raws li lub hauv paus ntsiab lus dav dav, thaum muaj teeb meem tshwm sim, tag nrho cov kab ke yuav tsum raug tshuaj xyuas tag nrho thaum lub zog tsis ua haujlwm, uas suav nrog cov hauv qab no:

(1) Fais fab mov: Siv lub multimeter los xyuas seb puas muaj hluav taws xob tom qab lub ntsiab hloov hluav taws xob (contactor) thiab tswj fuse, uas yuav txiav txim siab qhov muaj feem cuam tshuam ntawm cov khoom no.

(2) Rectifier: Lub rectifier txais yuav peb-theem kev tswj xyuas tag nrho cov choj rectifier Circuit Court, rau thyristors, rau pulse transformers thiab rau pawg ntawm kev tiv thaiv-capacitance absorbing ntsiab.

Txoj hauv kev yooj yim los ntsuas lub thyristor yog ntsuas nws cov cathode-anode thiab lub rooj vag-cathode tsis kam nrog multimeter hluav taws xob thaiv (200Ω block), thiab thyristor tsis tas yuav raug tshem tawm thaum ntsuas. Raws li ib txwm muaj, qhov kev tiv thaiv anode-cathode yuav tsum tsis muaj kawg, thiab lub rooj vag-cathode kuj yuav tsum nyob nruab nrab ntawm 10-35Ω. Loj dhau los yog me me qhia tau hais tias lub rooj vag ntawm thyristor no ua tsis tau, thiab nws tsis tuaj yeem ua rau kev coj ua.

(3) Inverter: Lub inverter suav nrog 4 (8) ceev thyristors thiab 4 (8) pulse transformers, uas tuaj yeem kuaj xyuas raws li cov txheej txheem saum toj no.

(4) Transformer: Txhua winding ntawm txhua transformer yuav tsum tau txuas nrog. Feem ntau, qhov tsis kam ntawm thawj sab yog txog kaum ntawm ohms, thiab qhov kev tawm tsam thib ob yog ob peb ohms. Nws yuav tsum tau muab sau tseg tias thawj sab ntawm qhov nruab nrab zaus voltage transformer yog txuas nrog rau lub load, yog li nws tus nqi kuj yog xoom.

(5) Capacitors: Capacitors txuas nrog rau qhov sib npaug nrog cov khoom thauj tuaj yeem raug punctured. Capacitor feem ntau yog ntsia rau hauv pawg ntawm lub capacitor khib. Cov pab pawg ntawm cov capacitors yuav tsum tau punctured yuav tsum tau txiav txim ua ntej thaum kuaj. Tshem tawm qhov kev sib txuas ntawm lub npav npav ntawm txhua pab pawg ntawm cov capacitors thiab lub tsheb npav tseem ceeb, thiab ntsuas qhov kev tawm tsam ntawm ob lub npav npav ntawm txhua pawg ntawm cov capacitors. Feem ntau, nws yuav tsum yog infinite. Tom qab paub meej tias cov pab pawg tsis zoo, tshem tawm cov phaj tooj liab ntawm txhua lub capacitor ua rau lub tsheb npav, thiab xyuas txhua lub capacitor kom pom lub capacitor tawg. Txhua lub capacitor yog tsim los ntawm ntau lub cores. Lub plhaub yog ib tug ncej, thiab lwm tus ncej yog coj mus rau qhov kawg cap los ntawm ib tug insulator. Feem ntau, tsuas yog ib qho tseem ceeb tau tawg. Yog tias cov hlau lead ntawm lub insulator dhia tawm, lub capacitor tuaj yeem siv txuas ntxiv mus. Lwm qhov txhaum ntawm lub capacitor yog cov roj to, uas feem ntau tsis cuam tshuam rau kev siv, tab sis xyuam xim rau kev tiv thaiv hluav taws.

Lub kaum sab xis steel qhov twg lub capacitor raug ntsia yog insulated los ntawm lub capacitor ncej. Yog hais tias lub rwb thaiv tsev puas yuav ua rau hauv lub ntsiab Circuit Court, ntsuas qhov kev tiv thaiv ntawm lub plhaub capacitor thiab lub capacitor thav duab kom txiav txim siab qhov rwb thaiv tsev ntawm qhov no.

1. Dej-txias cable: Lub luag haujlwm ntawm cov dej txias cable yog txuas rau nruab nrab zaus fais fab mov thiab induction coil. Lub zog torsion, qaij thiab twists nrog lub tshuab ua kom sov lub cev, yog li nws yooj yim rau kev tawg ntawm qhov hloov pauv tau yooj yim (feem ntau yog qhov kev sib txuas ntawm lub qhov cub lub cev) tom qab lub sijhawm ntev. Tom qab cov dej-txias cable raug txiav tawm, lub zog nruab nrab zaus tsis tuaj yeem pib ua haujlwm. Thaum paub meej tias lub cable puas lawm, thawj zaug disconnect tus dej-txias cable los ntawm lub capacitor tso zis tooj liab bar, thiab ntsuas qhov tsis kam ntawm cable nrog ib tug multimeter (200Ω block). Tus nqi tiv thaiv yog xoom thaum nws zoo li qub, thiab nws yog infinite thaum nws raug rho tawm. Thaum ntsuas nrog lub multimeter, lub qhov cub lub cev yuav tsum tig mus rau qhov chaw pov tseg kom cov dej-txias cable poob, kom qhov tawg tuaj yeem sib cais tag nrho, yog li nws tuaj yeem raug txiav txim siab tias nws puas tawg los yog tsis.
