"Cob phum txhua tus cag hlau" yuav ua rau txoj kev sib tw Hong Kong "smashing tsheb"
Hong koob lub tsheb thauj mus los, feem ntau hu ua "smashing cars", tau nyob rau hauv Hong Kong txij thaum 1904 thiab muaj keeb kwm txog ntau tshaj 100 xyoo. Lawv tseem nyiam cov pej xeem Hong Kong thiab cov neeg tuaj ncig xyuas tebchaws. Lawv mus txhua hnub nyob rau hauv txoj kev ntawm Hong Kong thiab yog tag nrho ntawm kev loj hlob. Ib qho tseem ceeb tshaj plaws yog tias nws muaj "core" uas yog ib txwm me. Qhov "core" tau hloov kho dua los ntawm Yongji Electric Company ntawm Tuam Tshoj CRRC.
Nyob rau lub Ib Hlis 28, 2016, lub tuam txhab hluav taws xob nyob ruaj khov uas tsim los ntawm CRRC Yongji Tsav Lag Luam rau Hong Kong Tram dhau qhov kev soj ntsuam ntawm University Jiaotong University, Southwest Jiaotong University, China CRRC-related units thiab Hong Kong Tramways Co., Ltd. tus kws tshaj lij pom tau hais tias cov qauv tsim tau mus txog qib siab ntawm cov hluav taws xob hluav taws xob thiab muaj cov kev cai rau kev tsav tsheb thiab kev ua haujlwm.
Thawj fais fab tsav tsheb ntawm Hong koob hluav taws xob tsheb ciav hlau yog ib qho DC tsav hluav taws xob uas siv los ntawm DC motor. Nyob rau hauv 2008, Yongji Electric Company tsim lub AC asynchronous hluav taws xob tsav system raws li cov cai ntawm Hong koob Tram Company. Nws tuaj yeem ua haujlwm zoo zog, traction fais fab thiab lub tswv yim txij nkawm thaum uas txhim kho txoj kev cia siab ntawm qhov system. Thawj AC asynchronous hluav taws xob tsav tsheb tau xa mus rau tus neeg siv nyob rau hauv lub Plaub Hlis 2009. Qhov no kuj yog thawj zaug uas ib puas xyoo ntawm "smashing tsheb" tau ua ib qho kev txhim kho tshiab ntawm qhov hluav taws xob tsav. Txog rau tam sim no, Yongji Electric tau npaj muaj 71 teeb meem ntawm cov cuab yeej asynchronous traction rau Hong Kong Tramways, uas siab tswj lub vitality ntawm "brakes".
Nrog rau kev nce tsheb hauv online ntawm AC asynchronous systems, lub peev xwm ntawm Hong koob Fais Railway DC fais fab chaw nres tsheb yog maj tsis tuaj yeem txhawb ntxiv AC asynchronous systems khiav hauv online tib lub sijhawm. Rau qhov kawg no, thaum xyoo 2015, Yongji Electric Co., Ltd. pib tsim ib qho kev txuag thiab txuag hluav taws xob AC daim kom ruaj khov kho hluav taws xob rau Hong koob trams. Tam sim no, qhov system ua tiav tsab ntawv pov thawj, hom kev xeem, hauv kev sib koom hauv kev sib koom hauv av thiab los ntawm kev txheeb xyuas, yuav ua tiav cov kev ntsuas kev lag luam.
Tam sim no, tsuas yog ob peb lub tuam txhab xws li Alstom ntawm Fabkis muaj kev paub nyob rau hauv daim ntawv thov kev lag luam ntawm cov cuab yeej magnet traction tshuab, thiab kev txhim kho ntawm cov kev sib tshuam sab nrauv sab nraud synchronous lub cev muaj zog thiab daim txiag zeb txuas mus tas li tseem nyob hauv nws cov me nyuam, thiab tsis tau thov mus rau lub nroog cov tsheb ciav hlau. teb. Hong Kong Tram Permanent Hlau Hluav Taws Xob Drive System yog ib qho khoom tshiab tsim los ntawm Yongji Electric Company hauv cheeb tsam ntawm railcars tom qab mastering ruaj khov magnet tswj technologies xws li hluav taws xob tsheb thiab marine propulsion systems.
Cov tshuab hluav taws xob tsis tu ncua muaj kev pom zoo xws li me me, lub cev nyhav, kev ua haujlwm siab, qis qis, kev ruaj khov thiab kev nyab xeeb, thiab tsim nyog rau cov tsheb nqaj hlau. Muaj ntau qhov kev tshawb nrhiav thiab kev ua haujlwm hauv tsev thiab sab nrauv qhia tias nws yog qhov zoo tshaj hauv cov tsheb thauj mus los hauv nroog loj yog tias nws yog cov khoom zoo thiab txuag txuag. Raws li kev khiav hauj lwm hauv kev khiav hauj lwm tib, lub tshuab hluav taws xob nyob sab nraud tuaj yeem txuag tau ntau tshaj 20% zog piv nrog lub asynchronous traction system. Nce raws li cov kev ua kom rov qab ua tau zoo dua. Nrog rau lub sijhawm tamsim no Hong koob khiav 10 xuab moos ib hnub, cov lus qhia txog 120 mais, txhua xyoo siv hluav taws xob asynchronous traction yog 50,000 degrees, thiab cov khoom ntiag tug uas muaj peev xwm txuag tau txuag tsawg kawg yog 9000 degrees ib xyoo.
