Nruab nrab zaus qhov chaw vuam tshuab ua lub luag haujlwm tseem ceeb hauv ntau yam kev lag luam, ua kom yooj yim rau cov txheej txheem vuam tau zoo thiab meej.Cov tshuab no feem ntau siv IGBT (Insulated Gate Bipolar Transistor) modules los tswj cov vuam tam sim no thiab qhov hluav taws xob, kom ntseeg tau qhov tseeb thiab zoo ib yam welds.Txawm li cas los xij, ntsib IGBT module tswb tuaj yeem cuam tshuam kev tsim khoom thiab ua rau muaj teeb meem.Hauv tsab xov xwm no, peb yuav tham txog cov laj thawj ntawm IGBT module tswb hauv nruab nrab zaus qhov chaw vuam tshuab thiab muab cov kev daws teeb meem zoo los daws cov teeb meem no.
Feem ntau ua rau IGBT Module Alarms
- Overcurrent Conditions: Ntau dhau tam sim no dhau los ntawm IGBT module tuaj yeem ua rau lub tswb nrov dhau.Qhov no tej zaum yuav tshwm sim los ntawm ib qho kev nce ceev hauv load los yog malfunction nyob rau hauv lub tam sim no tswj Circuit Court.
- Luv Circuits: Short circuits nyob rau hauv lub vuam Circuit Court lossis IGBT module nws tus kheej tuaj yeem ua rau lub tswb nrov.Cov luv luv no tuaj yeem tshwm sim los ntawm cov yam ntxwv xws li kev tiv thaiv tsis ua haujlwm, kev rwb thaiv tsev tsis zoo, lossis kev sib txuas tsis raug.
- Overtemperature: Qhov kub thiab txias tuaj yeem ua rau kev ua haujlwm ntawm IGBT modules.Overheating tuaj yeem tshwm sim vim qhov tsis txaus cua txias, ua haujlwm ntev, lossis qhov cua tsis zoo nyob ib puag ncig cov modules.
- Voltage Spikes: Cov hluav taws xob nrawm nrawm tuaj yeem ua rau muaj kev ntxhov siab ntawm IGBT modules, uas ua rau lub tswb nrov.Cov spikes no yuav tshwm sim thaum lub zog hloov pauv lossis thaum hloov cov khoom loj.
- Qhov teeb meem ntawm qhov rooj tsav tsheb: Kev tsis txaus lossis tsis raug lub rooj vag tsav tsheb tuaj yeem ua rau tsis raug hloov ntawm IGBTs, ua rau lub tswb nrov.Qhov no tuaj yeem tshwm sim los ntawm teeb meem nrog kev tswj xyuas circuitry lossis teeb liab cuam tshuam.
Kev daws teeb meem
- Tsis tu ncua: Ua raws li lub sijhawm ua haujlwm niaj hnub los tshuaj xyuas thiab ntxuav IGBT modules.Qhov no suav nrog kev kuaj xyuas cov kev sib txuas xoob, cov khoom puas, lossis cov cim qhia ntawm overheating.
- Kev soj ntsuam tam sim no: Txhim kho cov kev soj ntsuam tam sim no kom ntseeg tau tias cov vuam tam sim no nyob hauv qhov txwv tsis pub muaj kev nyab xeeb.Siv cov limiters tam sim no thiab tiv thaiv circuits los tiv thaiv cov xwm txheej overcurrent.
- Kev tiv thaiv luv luv: Siv cov txheej txheem rwb thaiv tsev kom zoo thiab tsis tu ncua xyuas cov vuam siv hluav taws xob kom muaj peev xwm luv luv.Nruab fuses thiab Circuit Court breakers los tiv thaiv qhov tshwm sim tam sim no.
- Cua txias thiab cua tshuab: Txhim kho lub tshuab cua txias los ntawm kev siv cov dab dej kub zoo, kiv cua, thiab ua kom muaj cua zoo nyob ib puag ncig IGBT modules.Saib xyuas qhov kub thiab txias thiab siv cov ntsuas kub kom ua rau lub tswb yog tias muaj cua sov dhau.
- Kev tswj hluav taws xob: Txhim kho qhov kev tswj hwm qhov hluav taws xob kom txo tau qhov voltage spikes thiab fluctuations.Surge protectors thiab voltage regulators tuaj yeem pab tswj lub zog ruaj khov rau lub tshuab vuam.
- Gate Drive Calibration: Calibrate thiab sim lub rooj vag tsav circuitry tsis tu ncua kom paub meej thiab raws sij hawm hloov ntawm IGBTs.Siv cov khoom zoo ntawm lub qhov rooj tsav tsheb thiab tiv thaiv cov teeb meem rhiab ntawm kev cuam tshuam.
IGBT module ceeb toom nyob rau hauv nruab nrab zaus qhov chaw vuam tshuab tuaj yeem hais tau zoo los ntawm kev sib xyaw ua ke ntawm kev tiv thaiv thiab cov lus teb raws sijhawm.Los ntawm kev nkag siab txog cov laj thawj ntawm cov tswb no thiab siv cov kev daws teeb meem tsim nyog, cov neeg tsim khoom tuaj yeem tswj hwm qhov kev ntseeg tau thiab kev ua haujlwm ntawm lawv cov txheej txheem vuam.Kev saib xyuas tsis tu ncua, kev tiv thaiv hluav taws xob zoo, kev tswj xyuas qhov kub thiab txias, thiab kev tswj lub rooj vag kom raug tag nrho ua rau txo qis IGBT module tswb thiab ua kom muaj kev ua haujlwm zoo hauv ntau daim ntawv thov kev lag luam.
