Mng'anjo yapakati yapakati ndi chipangizo chamagetsi chomwe chimasintha mphamvu ya 50Hz AC kukhala mphamvu yapakati (300Hz mpaka 100Hz), kenako ndikusintha mphamvu ya magawo atatu a AC kukhala mphamvu ya DC, kenako ndikusintha mphamvu ya DC kukhala yosinthika yapakati pafupipafupi, yomwe imayenda kudzera mu ma capacitor ndi ma induction coil.Pangani mizere yamphamvu yamaginito yamphamvu kwambiri, kudula zitsulo mu koyilo yolowera, gwiritsani ntchito mfundo ya electromagnetic induction kuti mupange chitsulo chachikulu chachitsulo, kutentha zitsulo, ndikuzisungunulira.
The medium frequency induction ng'anjo ndi discrete system load.Panthawi yogwira ntchito, mafunde amtundu wa ma harmonic amalowetsedwa mu gridi yamagetsi, kuchititsa kuti mphamvu yamagetsi iwonongeke pamtundu wa gridi yamagetsi, kuchititsa kusinthasintha kwa magetsi mu gridi yamagetsi, komanso kukhudza khalidwe la magetsi ndi chitetezo cha zida. .Popeza malonda mphamvu ya ng'anjo wapakatikati pafupipafupi amakhala pafupipafupi wapakatikati kudzera rectification pafupipafupi Converter, gululi mphamvu adzapanga ambiri oipa mkulu-kuti harmonics pa ntchito, amene ndi mmodzi wa waukulu mkulu-kuti harmonic magwero mu mphamvu grid katundu.
Zisanu makhalidwe wapakati pafupipafupi ng'anjo
1. Sungani ndalama
Kutentha kwachangu, zokolola zambiri, kutsika kwa mpweya wa oxidation carburization, kupulumutsa zida ndi mtengo wake, ndikutalikitsa moyo wautumiki wa zida zowononga.
Chifukwa mfundo ya ng'anjo yapakatikati yopangira ma frequency ndi electromagnetic, kutentha komwe kumapangidwa ndi ng'anjo yapakatikati yamafupipafupi kumapangidwa ndi chitsulo chokha.Ogwira ntchito wamba amatha kugwira ntchito yopitilira muyeso mkati mwa mphindi khumi atagwiritsa ntchito ng'anjo yapakatikati, popanda kufunikira kopanga ng'anjo.Ogwira ntchitowo anayamba kuwombera ndi kusindikiza ng'anjo pasadakhale.Chifukwa njira yotenthetsera iyi imatenthetsa mwachangu ndipo imakhala ndi okosijeni pang'ono, kutulutsa kwa okosijeni kwapakati pafupipafupi Kutentha kwazitsulo kumakhala 0.5%, kutulutsa kwa okosijeni kwa ng'anjo ya gasi ndi 2%, ndipo ng'anjo ya malasha yaiwisi imaposa 3%.Kutentha kwapakati pafupipafupi kumapulumutsa Zopangira, poyerekeza ndi ng'anjo za malasha, tani imodzi yazitsulo imapulumutsa 20-50KG mbale zosapanga dzimbiri zosapanga dzimbiri.Mlingo wake wogwiritsa ntchito zopangira ukhoza kufika 95%.Chifukwa chotenthetseracho chimakhala chofanana komanso kusiyana kwa kutentha pakati pa pachimake kumakhala kochepa, moyo wautumiki wa kufa kwa forging umachulukitsidwa kwambiri panthawi yopanga.The forging roughness ndi otsika kuposa 50um, ndi processing luso ndi zopulumutsa mphamvu.Kutentha kwapakati pafupipafupi kumatha kupulumutsa mphamvu ndi 31.5% -54.3% poyerekeza ndi kutentha kwamafuta, ndi kutentha kwagesi Kupulumutsa Mphamvu 5% -40%.Kutentha kwabwino ndikwabwino, kuchuluka kwa zinyalala kumatha kuchepetsedwa ndi 1.5%, kuchuluka kwa zotulutsa kumatha kuwonjezeka ndi 10% -30%, ndipo moyo wautumiki wa chida cha abrasive ukhoza kukulitsidwa ndi 10% -15%.
2. Malo otetezera chilengedwe
Malo abwino kwambiri aofesi, kukonza malo amaofesi a antchito ndi mawonekedwe amakampani, kuwononga ziro, kupulumutsa mphamvu.
Poyerekeza ndi masitovu a malasha, ng'anjo zotenthetsera zotenthetsera sizingafukidwenso ndi masitovu a malasha pansi pa kutentha kwakukulu, zomwe zimatha kukwaniritsa malamulo a Environmental Protection Agency.Kuphatikiza apo, imatha kupanga mawonekedwe amtundu wakunja wa kampaniyo ndikupanga chitukuko chamakampani opanga zinthu.Kutentha kwa induction ndikotentha kwa ng'anjo yamagetsi yamagetsi kuchokera kutentha kufika pa 100 ° C, mphamvu yogwiritsira ntchito mphamvu ndi yosakwana 30 ° C, ndipo kugwiritsira ntchito ma forgings kumakhala kosakwana 30 ° C.Njira yogawanitsa chakudya
3. Kutentha zipatso
Kutentha kwamtundu umodzi, kusiyana kochepa kwa kutentha pakati pa pachimake ndi pamwamba, kuwongolera kutentha kwapamwamba
Kutentha kolowera kumapangitsa kutentha muchitsulo chokha, kotero kutentha kumakhala kofanana komanso kusiyana kwa kutentha pakati pa pachimake ndi pamwamba kumakhala kochepa.Kugwiritsa ntchito njira yowongolera kutentha kumatha kuwongolera kutentha, kuwongolera mtundu wazinthu komanso kuchuluka kwazomwe zikuchitika.
4. Mtengo
Ng'anjo yapakati yapakati imatenthetsa mwachangu, chitsulo chosungunula chimagwiritsa ntchito mphamvu yamagetsi yamagetsi yosapitirira madigiri 500, ndipo kusungunuka kwake kumakhala kokwanira komanso kofulumira.
5. Kuchita kwachitetezo
Njira yowunikira yakutali ya ng'anjo yamagetsi yapakati pafupipafupi imasankhidwa, yomwe ili yoyenera malo opangira mafakitale.Mphamvu zotsutsana ndi kusokoneza komanso chitetezo chachikulu.Palibe waya wolumikizidwa pakati pa chipangizo chogwiritsira ntchito ndi chipangizo cholamulidwa, ndiko kuti, kuwongolera kutali.Pazinthu zonse zovuta, dinani makiyi a remote control kuchokera patali.Atalandira malangizo, ng'anjo yamagetsi yapakati pafupipafupi imatha kumaliza ntchito zofananira pang'onopang'ono molingana ndi njira yabwino.Chifukwa ng'anjo yamagetsi ndi chipangizo chamagetsi chamagetsi, sichimangokhala chotetezeka, komanso chingapewe kuwonongeka kwa ng'anjo yamagetsi chifukwa cha mantha omwe amayamba chifukwa cha zolakwika zogwirira ntchito.
Chifukwa chiyani ng'anjo yapakatikati imapanga ma harmonics
Ma Harmonics adzayika pachiwopsezo chachitetezo cha gridi yamagetsi.Mwachitsanzo, mphamvu yamagetsi yamagetsi imapangitsa kuti chitsulo chiwonongeke kwambiri mu thiransifoma, chomwe chimapangitsa kuti thiransifomayo itenthe, kuchepetsa kutulutsa kwa thiransifoma, kuonjezera phokoso la thiransifoma, ndikuika pangozi moyo wautumiki wa thiransifoma. .Kumamatira kwa mafunde a harmonic kumachepetsa kusinthasintha kosalekeza kwa woyendetsa ndikuwonjezera kutayika kwa mzere.Vuto la Harmonic limakhudza magwiridwe antchito amagetsi ena pagululi, zomwe zimapangitsa kuti pakhale zolakwika pazida zowongolera zokha ndikutsimikizira muyeso wolakwika.Harmonic voliyumu ndi zamakono zimakhudza magwiridwe antchito a zida zolumikizirana zotumphukira;kusakhalitsa overvoltage ndi zosakhalitsa overvoltage chifukwa harmonics kuwononga kutchinjiriza wosanjikiza wa makina ndi zipangizo, chifukwa cha magawo atatu yochepa-wagawo zolakwika ndi kuwonongeka kwa thiransifoma;voteji ya harmonic ndi Kuchuluka kwa zomwe zikuchitika kumapangitsa kuti pakhale kumveka kwapang'onopang'ono komanso kumveka kofanana mu gululi yamagetsi, zomwe zimapangitsa ngozi zazikulu.Munthawi yonse yopangira magetsi osinthira magetsi, magetsi oyamba okhazikika a DC ndi magetsi osinthira masikweya, omwe ndi ofanana ndi kuchuluka kwa mafunde a sine okhala ndi mafunde ambiri apamwamba kwambiri.Ngakhale kuti gawo la post-siteji likufunika fyuluta, ma harmonics sangathe kusefedwa kwathunthu, zomwe ndizomwe zimayambitsa ma harmonics.
Harmonic mphamvu yapakati pafupipafupi ng'anjo
Mphamvu yotulutsa ng'anjo yapakatikati yamafupipafupi ndi yosiyana, ndipo ma harmonics amasiyananso:
1. Mphamvu yachilengedwe ya ng'anjo yapakatikati yapakati yamphamvu kwambiri ili pakati pa 0.8 ndi 0.85, mphamvu yogwiritsira ntchito mphamvu ndi yayikulu, ndipo ma harmonic ndi apamwamba.
2. Mphamvu yachirengedwe ya ng'anjo yapakati yapakati pa mphamvu yochepa imakhala pakati pa 0.88 ndi 0.92, ndipo mphamvu yowonjezera mphamvu ndiyochepa, koma ma harmonic ndi apamwamba kwambiri.
3. The ukonde mbali harmonics wa wapakatikati pafupipafupi ng'anjo makamaka 5, 7 ndi 11.
Harmonic control njira yapakati pafupipafupi ng'anjo
Zosefera zosinthidwa kamodzi za 5, 7, 11 ndi 13 zidapangidwa.Asanalipire chipukuta misozi, mphamvu ya ulalo wosungunula ng'anjo yamakasitomala wapakati ndi 0.91.Zida zolipirira zosefera zitayamba kugwira ntchito, chiwongola dzanja chachikulu ndi 0.98 capacitive.Zida zolipirira zosefera zikayamba kugwira ntchito, kuchuluka kwamagetsi osokonekera (total harmonic distortion value) ndi 2.02%.Malinga ndi mphamvu khalidwe muyezo GB/GB/T 14549-1993, ntchito voteji harmonic (10KV) mtengo ndi otsika kuposa 4.0%.Pambuyo pochita zosefera pa 5th, 7th, 11th and 13th harmonic currents, zosefera zili pafupifupi 82∽84%, zomwe zimaposa mtengo wowongolera wamakampani athu.Zosefera zolipirira ndizabwino.
