Qhov kaum xyoo tom ntej yog lub hnub nyoog golden ntawm kev txuag hluav taws xob. Kev txuag kev siv hluav taws xob npog siv ntau yam, nrog rau kev siv hluav taws xob, kev txuag hluav taws xob, kev txuag hluav taws xob thiab txua hluav taws xob thiab kev siv technology ntawm kev lag luam xws li hlau thiab hlau, nonferrous metals, petroleum thiab petrochemicals, chemicals thiab cov khoom siv hauv tsev. Nws tau muab faib ua peb qhov tseem ceeb: kev tsim, kev tsim vaj tse thiab cov tshuab electromechanical. Tsav lub zog txuag yog qhov tseem ceeb ntawm cov hluav taws xob muaj kev txuag.
Peb qhov kev sib tham ntawm cov txheej txheem kev sib tham rau "Kev Tsim Kho Hluav Taws Xob thiab Kev Tiv Thaiv Kev Nyab Xeeb Kev Lag Luam Tag Nrho" tau tag nrho cov kev kawm tiav thiab yuav tsum tau muab los qhia thaum lub xyoo. Nws tau kwv yees tias Tuam Tshoj txoj kev tiv thaiv ntawm kev tiv thaiv ib puag ncig yuav nce 3.1 trillion rau lub sij hawm 12th tsib xyoos, qhov nce ntawm 121% ntawm qhov kev nqis peev ntawm 1.54 trillion yuan thaum lub sij hawm 11th tsib lub xyoos.
Tuam Tshoj tus ntau hom tsav lub zog qiv nyiaj rau 60% mus rau 70% ntawm Tuam Tshoj lub tag nrho industrial hwj chim noj, yog li lub zeem muag ntawm lub zog hluav taws xob txuag loj heev. Txawm li cas los xij, kev sib tw ua lag luam ntawm lub zog ntawm kev txuag hluav taws xob tau yog cov kev khaus thiab kev limhiam hauv ntau lub tshuab kev txuag hluav taws xob.
Raws li cov yeeb yam, tam sim no loj sub-sectors ntawm lub zog kev txuag hluav taws xob thiab teev cov tuam txhab, suav nrog cov hluav taws xob cog cua txias tshuab, hluav taws xob cog khoom nruab nrab, cov kev ntsuas thiab kev cia khoom, kev hloov tsheb, kev txuag hluav taws xob, kev siv hluav taws xob, kev siv hluav taws xob thiab lwm yam thiab lwm yam kev lag luam.
Txoj kev ua lag luam zeem muag ntawm qhov inverter yog tsim nyog. Nws yog taw tes qhia hais tias lub peev txheej lag luam rau cov neeg ua haujlwm siab-kev siab siab yog siab li 60 billion yuan.
Nyob rau hauv cov nqe lus ntawm zaus converters, muaj ib tug xov tooj ntawm teev tuam txhab, ua ntej ntawm tag nrho cov nyob rau hauv lub high-voltage inverter lag luam nrog lossis loj thov, nrog Hekang inverter, Rongxin Shares, Zhiguang Electric thiab Jinzi Tianzheng.
Qee lub tuam txhab tau tshwm sim nyob rau hauv daim ntawv ntawm cov neeg siv cov neeg taug kev, xws li Jiuzhou Electric thiab cov hwj chim, tag nrho cov uas muaj siab, nruab nrab thiab tsis tshua muaj hluav taws xob inverters. Tsis tas li ntawd, Kelu Electronics kuj muaj kev sib qhia hauv qhov no. Cov nruab nrab thiab tsis tshua muaj siab qis, tab sis feem cuam ntawm cov nyiaj tau los hauv kev khiav hauj lwm yog me me.
Peb zoo siab tshaj txog Jiuzhou Electric thiab Hekang zaus hloov dua siab tshiab. Tus qub muaj siab, nruab nrab thiab qis low-voltage full-range inverters. Nyob rau hauv 2009, cov nyiaj inverter tau 183 lab, accounting rau 48.59% ntawm cov nyiaj ua lag luam loj. Lub tom kawg yog kev lag luam tus thawj coj thiab tus txheem setter. , nrog 6kV thiab 10kV universal high-voltage inverter, vector tswj high-voltage inverter, synchronous tshuab high-voltage inverter. Ib tug brokerage hluav taws xob kev lag luam analyst ntse.
Cov tshuab hluav taws xob muaj txiaj ntsig zoo siab tsis txaus siv vim yog qhov tshwj xeeb ntawm lawv txoj cai nyiam. Nws qhia tau hais tias txij li tus nqi ntawm cov tshuab hluav taws xob ua haujlwm siab dua li cov qauv ntawm cov khoom qub, qhov nyiaj pabcuam nyiaj txiag yuav txo qhov sib txawv nruab nrab ntawm ob, yog li ua kom cov khw muag khoom muaj zog.
Nyob rau hauv cov nqe lus ntawm high-efficiency motors, nws tau sau ob peb lub kaus poom xws li Wolong Electric, Dunan Ib puag ncig, Tuobang, thiab Lapu Le Automation.
Qhov kev lag luam no tau them sai sai rau cov tuam txhab ua haujlwm nrog kev ua haujlwm zoo. Piv txwv, Wolong Electric yog tus thawj coj hauv kev lag luam sib txawv. Nws muaj servo tswj thiab txawv txav ntau zog tshuab, synchronous lub caij nplooj ntoos hlav hlau tshuab, high voltage qib traction transformer manufacturing tshuab, linear motor ntev stator thiab nws cov winding. High-end technology xws li technology. Ntawm lawv, nws high-power high-voltage inverter tau tiav ntau lawm. Cov kws lij choj saum toj no tau piav qhia tias Wolong Electric yog npaj los tsim cov txheej txheem lithium-ion roj teeb, uas yuav tsim kev txaus ntshai.
Txawm li cas los xij, kev sib tw ua lag luam ntawm lub zog ntawm kev txuag hluav taws xob tau yog cov kev khaus thiab kev limhiam hauv ntau lub tshuab kev txuag hluav taws xob.
Siv Rongxin Co., Ltd. ua piv txwv, nws yog ib qho chaw ua lag luam hauv high-power zog hauv hluav taws xob-txuag thiab noj-txo cov khoom. Ntawm lawv, high-voltage inverter thiab fais fab hauv hluav taws xob muaj zog-voltage dynamic reactive fais fab tuag taus ntaus ntawv (SVC) tsim thiab siv thiab ua yog qhov tseem ceeb ntawm cov nyiaj tau los. Los ntawm cov kev txiav txim ntawm cov kev txiav txim hauv thawj ib nrab ntawm 2010, SVC tau lees paub txog 47%, tab sis nws txoj kev sib tw ua lag luam tau pib khaus.
Tam sim no, ntau lub tuam txhab tau tsim SVC, nyob rau hauv uas daim phiaj yuav tsum tau ntau tshaj ntawm SVC, thiab Rongxin lub SVC competitor nyob rau hauv lub lag luam grid yog lub koom haum ntawm hluav taws xob fais fab; lub ntsiab rivals hauv cov kev lag luam hauv Circuit Court yog CSR Zhuzhou Times thiab Siyuan Electric. Thaum tam sim no, cov teeb meem ntawm SVC nyob rau hauv kev lag luam siv hlau hlau yog li ntawm 70%, thiab cov lag luam competing rau kev sib tw yog tsis pub dhau kaum; lub SVC peev xwm yuav tsum tau nyob rau hauv cov cua fais fab lag luam me me, kev them nyiaj raug ntau yam, thiab kev sib tw yog tsiv.
