Plaub Kev Kho Mob Ntawm Mitsubishi of Elevator
Plaub Qhov Kev Kho Mob ntawm Mitsubishi of Elevator
Fault 1: HOPE elevator muaj E7, DC overvoltage thiab undervoltage. Xyuas tias qhov kub thiab txias fuse ntawm lub hwj chim board (P203722B000G01) tau raug hlawv, thiab xyuas ntxiv tias tsis muaj teeb meem nrog lub capacitor, IGBT, thiab lub cev muaj zog coil. Hloov qhov kub thiab txias fuse tiv thaiv ntawm 154 degrees 2A thiab 220 ohms, hloov nws, thiab tom qab ntawd siv hluav taws xob thiab hlawv nws. Tom qab ntawd nws tau pom tias nws yog tshwm sim los ntawm ib tug luv luv Circuit Court nyob rau hauv lub TR1 field-effect transistor ntawm lub hwj chim board (P203722B000G01).
Qhov txhaum 2: Tom qab khiav lub HOPE elevator rau lub sijhawm, IGBT raug hlawv. Qhov hluav taws xob tau kuaj xyuas thiab tsis muaj teeb meem. Tom qab hloov qhov zaus hloov pauv hloov pauv, qhov hloov pauv zaus zaus tau luv luv dua nyob rau hauv ib hlis, ua rau E-board hlawv tawm. Tom qab hloov qhov zaus hloov dua siab tshiab module thiab E-board, nws tsis ntev ua ntej lawv hlawv dua. Tom qab ua qhov kev soj ntsuam kom ntxaws, nws tau pom tias lub rooj tsav xwm tiv thaiv surge (p203724b000g01) ntawm qhov zaus hloov pauv hloov pauv tau poob qis. Tom qab hloov lub anti surge board, E-board, thiab zaus hloov dua siab tshiab module, zaus hloov dua siab tshiab module tsis tau hlawv dua.
Fault 3: Lub 89 relay tsis ua haujlwm, thiab lub elevator kev nyab xeeb Circuit Court txuas nrog. Sab nraud Circuit Court yog qhov qub, tab sis nws tsis tuaj yeem pib (lub 89 relay tsis ua haujlwm, thiab 89 qhov taw qhia teeb tsis nyob). Ua ntej, ib zaug ntxiv lees paub qhov kev ua haujlwm ib txwm ua ntawm 29 kev nyab xeeb Circuit Court. Peb tsis tuaj yeem xav tias qhov kev nyab xeeb Circuit Court yog qhov qub vim tias lub teeb qhia 29 tau qhib. Kev ruaj ntseg Circuit Court yog ncaj qha nkag mus rau lub rooj tsavxwm P1 los ntawm 79 lub davhlau ya nyob twg hloov thiab txwv tam sim no. Yog li ntawd, qee zaum qis voltage kuj tuaj yeem nkag mus rau P1 pawg thawj coj saib, ua rau muaj qhov tsis zoo ntawm qhov kev nyab xeeb Circuit Court yog qhov qub. Txawm li cas los xij, qis voltage tsis tuaj yeem thawb qhov kev txiav txim ntawm 89 relay. Yog li thaum lub luv luv Circuit Court kev ruaj ntseg tsis loj heev, nws yuav tsis hlawv lub fuse, tab sis ua rau qhov tshwm sim no. Peb tuaj yeem ntsuas qhov kev tiv thaiv hauv av ntawm kev nyab xeeb Circuit Court thiab txiav txim siab qhov voltage ntawm txhua qhov chaw ntawm kev nyab xeeb Circuit Court. Yog hais tias qhov kev nyab xeeb Circuit Court yog ib txwm, peb tab tom kuaj xyuas seb W1C-P09 tus pin ntawm P1 board outputs tsawg voltage thiab raug txiav. Yog hais tias qhov kev nyab xeeb Circuit Court yog ib txwm, peb tab tom kuaj xyuas seb W1C-P09 tus pin ntawm P1 board outputs tsawg voltage. Raws li cov zis ntawm P1 board ntawm qhov taw tes no tau yooj yim puas, tsuav yog peb saib cov zis transistor thiab xaim ntawm lub rooj tsavxwm p1, feem ntau peb tuaj yeem pom qhov ua txhaum.
Fault 4: Thaum lub qhov rooj kaw ib nrab thiab qhib dua, kev sib txuas ntawm lub phaj tiv thaiv kev nyab xeeb ntawm lub qhov rooj yuav tawg lossis luv luv vim yog lub qhov rooj nquag txav. Qhov no yog tshwm sim los ntawm kev cuam tshuam ntawm kev tiv thaiv kev ruaj ntseg phaj thaiv thaum lub qhov rooj txav mus, ua rau lub qhov rooj kaw ib nrab thiab qhib dua. Los ntawm kev ntsuas qhov txuas ntxiv ntawm 420 thiab 30, 420 thiab 30A, nws tuaj yeem txiav txim siab tias qhov teeb meem nyob rau sab nraud. Qhov kev ua txhaum no feem ntau tshwm sim los ntawm cov xov hlau tawg ntawm cov phaj tiv thaiv kev nyab xeeb thiab cov ntaub thaiv lub teeb, nrog rau kev sib cuag tsis zoo lossis kev hloov tsis raug ntawm kev tiv thaiv kev tiv thaiv phaj. Lub elevator muaj qhov khoov ntawm lub teeb kab hlau rhuav thiab lub ntsaws rau sab xis ntawm lub teeb kab hlau rhuav, thiab cov xov hlau sab hauv tsis zoo. Cov hlau tawg no yog ib qho txhaum ntawm lub teeb kab hlau rhuav.
