Nyob rau hauv tsab xov xwm peb yuav tham txog ABB zaus converters, uas yog siv los tswj fais fab motors. Nrog kev pab los ntawm cov cuab yeej zoo li no, koj tuaj yeem hloov kho lub sijhawm thiab nrawm, thiab qhov tseem ceeb tshaj plaws, tshem tawm tag nrho cov teeb meem tshwm sim xws li pib tam sim no. Thaum hloov tam sim no ncaj qha mus rau alternating tam sim no, nthwv dej (square, sinusoidal) yog tsim los ntawm inverter. Raws li nrog rau lwm qhov chaw siv hluav taws xob, lub zaus hloov pauv yuav tsum muaj kev ruaj ntseg thiab yuav tsum muab tam sim no txaus los txhawb lub zog ntawm tag nrho cov kab ke.
Vim li cas peb thiaj xav tau cov hloov pauv zaus
Nws yog ib qho tsim nyog sau cia tias ABB zaus hloov pauv tau tau txais txiaj ntsig dav niaj hnub no, lawv tau siv ntau hauv kev lag luam. Hauv kev tsim khoom, nws yog ib qho tseem ceeb kom khaws cov drives kom tsawg li sai tau. Vim li no, tag nrho cov khoom ntawm cov zaus hloov pauv tau nruab rau hauv lub tsev nyob ze. Tau kawg, qhov kev npaj ntawm cov khoom no muaj nws qhov tsis zoo - kev ua tsis tiav ntawm tag nrho cov cuab yeej yuav tshwm sim.
Cov khoom siv yuav tsum tau ua kom yooj yim rau pib lub cav thiab tom qab ntawd tswj nws. Cov "hlwb" muaj ntau qhov chaw uas tso cai rau koj los hloov kho kom zoo. Peb yuav tham txog qhov no thiab ntau ntxiv tom qab hauv tsab xov xwm, thiab qhov tseem ceeb tshaj plaws, peb yuav txiav txim siab nthuav dav cov lej yuam kev ntawm ABB zaus converters.
Kho ntawm chastotnikov
Raws li kev kho ntawm chastotnikov, feem ntau ua tsis tau zoo los tsim nws yog tias chav tswj tsis raug. Tab sis muaj cov qauv uas tsim los ntawm lub hauv paus modular. Raws li txoj cai, cov no yog cov khoom siv uas nws lub zog yog 100 kW lossis ntau dua. Yog li ntawd, daim duab ua haujlwm tau yooj yim heev thiab cov peev txheej tau nce ntxiv. Qhov tseem ceeb tshaj plaws uas yuav ua kom muaj kev ua haujlwm zoo ntawm lub cuab yeej yog kev kuaj mob raws sijhawm. Nws tseem tsim nyog sau cia tias lub cuab yeej yog qhov nyuaj heev, thiab cov teeb meem yuav tshwm sim thaum lub sijhawm ua haujlwm.
zaus converters yog cov khoom siv rhiab heev vim cov khoom siv tau muaj kev nyuaj siab heev. Feem ntau, teeb meem nyob hauv software. Qhov ntau dua nta ib lub cuab yeej muab, qhov ntau dua nws yuav ua tsis tiav. Kev kho cov cuab yeej yog qhov nyuaj thiab kim, tab sis koj tuaj yeem kho qee qhov kev puas tsuaj ntawm koj tus kheej yog tias koj paub yuav ua li cas tuav cov hlau thiab cov ntsia hlau.
Bug fixes
Lub tshuab cua txias hauv lub tshuab hloov zaus ua lub luag haujlwm tseem ceeb. Qhov tseeb, qhov no yog "qhov mob taw tes" ntawm tag nrho ABB zaus converter. Rautxhawm rau ua kom lub neej muaj xwm txheej ceev, koj yuav tsum tau tshuab lub tshuab radiator nrog compressed cua tsawg kawg ib hlis ib zaug. Tab sis nws yuav zoo dua yog tias koj tshuab los ntawm tag nrho cov ntaub ntawv kom tsis txhob muaj cov hmoov av txawm nyob rau ntawm lub rooj tsavxwm. Tom qab tag nrho, xav txog qhov tseeb tias cov plua plav ua hluav taws xob zoo li qub, muaj peev xwm ua rau nws. Thiab zoo li qub yog tus yeeb ncuab phem tshaj plaws ntawm cov khoom siv semiconductor. Nws tseem tsim nyog sau cia qhov tseeb tias chastotniki rau peb-theem hluav taws xob motors ntshai ntawm overloads. Yog li ntawd, kev ua haujlwm yuav tsum tau ua kom maj mam thiab raug raws li qhov ua tau.
IGBT-cov yawm sij tau nruab rau ntawm lub tshuab hluav taws xob. Cov yawm sij no ncaj qha tswj lub tshuab hluav taws xob, lawv hloov cov tam sim no ncaj qha mus rau qhov hloov tam sim no. Tab sis cov khoom los ntawm kev ua haujlwm yog cua sov. Nws tuaj yeem ua rau tus yuam sij kom kub dhau thiab kub hnyiab.
tub yees thiab condensers
Nws yog ib qho zoo heev los nrhiav cov kiv cua hluav taws xob uas tso cai kom txias ntawm lub tshuab hluav taws xob. Qee zaum nws yog ib qho tsim nyog los xyuas qhov kev ua tau zoo ntawm lub tshuab ua kom txias kom ntseeg tau tias qhov ua tau zoo ntawm cov cua txias ntawm ABB zaus converter. Nws yuav tsum tau muab sau tseg tias cov plua plav nyob rau hauv cov hniav yuav ua rau ib tug txo nyob rau hauv lub rotor ceev. Tab sis lub cav fais fab twb tsis tshua muaj, muaj kuab paug yuav ua rau qhov tseeb tias huab cua ntws tsis txaus rau qhov txias txias.
Lwm qhov teeb meem, uas cuam tshuam tsis yog rau chastotnikov nkaus xwb, yog electrolytic capacitors. Lawv feem ntau raug them thiab tso tawm, ua rau muaj kev hnav ntau dhau thiab kev laus. ATRaws li qhov tshwm sim, lawv cov capacitance poob qis, qhov kev cuam tshuam ntawm interpolar tshwm sim. Koj tuaj yeem kuaj pom qhov no los ntawm cov cim qhia sab nraud: lub cev tawg lossis o. Lub tshuab hloov zaus yog ib qho khoom siv nyuaj uas xav tau kev saib xyuas tas li.
Resistor hauv system
Koj tuaj yeem tswj hwm kev ua haujlwm ntawm lub converter ob leeg nrog kev pab los ntawm microcontroller thiab manually. Heev feem ntau, teeb meem tshwm sim nyob rau hauv ib tug sib txawv resistor, uas lub engine ceev yog tswj. Kev tswj kuj tseem tuaj yeem nqa tawm siv cov chaw taws teeb tswj ntawm lub inverter. Txhawm rau hloov lub faulty sab nraud resistor, nws yog txaus los hloov qhov kev xaiv hloov ntawm lub vaj huam sib luag tej thaj chaw deb nyob rau hauv qhov chaw. Lub resistor tuaj yeem hloov nws tus kheej nrog ib qho zoo sib xws. Nco ntsoov saib nws lub ntsej muag tus nqi, koj tuaj yeem pom nws hauv cov lus qhia rau ib lub cuab yeej tshwj xeeb.
tswb tswb
Ib zaus hloov pauv yog ib qho khoom siv nyuaj tswj los ntawm ib qho tshwj xeeb module. Tab sis nws tso cai rau koj los tswj thiab kuaj xyuas tag nrho cov kab ke. Feem ntau chastotniks tau nruab nrog qhov ntsuas uas qhia txog qhov yuam kev yog tias muaj. Nws yog ib qho tsim nyog sau cia tias txhawm rau tshem tawm qhov yuam kev feem ntau, nws yog txaus los xyuas cov cables thiab ceev cov terminals. Feem ntau yuam kev yog overloading. Nws tshwm sim vim muaj qhov sib txawv ntawm qhov sib txawv ntawm lub davhlau ya nyob twg thiab cov xaim.
Nws tseem tsim nyog sau cia tias qhov hloov pauv zaus rau peb-theem hluav taws xob lub cev muaj zog kuj tuaj yeem tswj tau los ntawm cov chaw taws teeb tswj. Thiab yog tias kev ncaj ncees ntawm cov xov hlau lossis kev sib txuas tau tawgplugs, qhov yuam kev yuav tshwm sim qhia qhov ua tsis tau.

Lub cev muaj zog tsis pib
Ib qho txhaum cai nrog ABB zaus hloov pauv yog qhov yuam kev uas lub cev muaj zog tsis pib. Tsuas muaj ob qho laj thawj:
- Motor failed.
- Lub kaw lus tswj tau puas lawm. Nyob rau hauv rooj plaub no, tsuas yog disassembled lub converter thiab hloov lub tswj board yuav pab tau.
Yog tias koj kho tsis tau koj tus kheej, koj yuav tsum hu rau cov kws tshaj lij. Tab sis feem ntau ntawm cov engineers, los ntawm txoj kev, ua kev kho modular - lawv hloov tag nrho cov chav nyob ib zaug, lawv tsis puzzled los ntawm kev tshawb fawb rau ib tug capacitor uas ua tsis tau tejyam. Tab sis qee zaum kev kho modular yog kim dua li yuav ABB zaus hloov pauv tshiab.
