Mafotokozedwe Akatundu

Mitundu yayikulu ndikugwiritsa ntchito ng'anjo zomira pansi pamadzi

Ng'anjo ya arc yomwe ili pansi pamadzi ndi ng'anjo yamagetsi yamagetsi yomwe imawononga mphamvu zambiri.Makamaka imakhala ndi chipolopolo cha ng'anjo, chivundikiro cha ng'anjo, ng'anjo ya ng'anjo, ukonde waufupi, njira yoziziritsira madzi, utsi wotulutsa utsi ndi njira yochotsera fumbi, chipolopolo cha electrode, makina osindikizira ndi kukweza ma electrode, makina otsegula ndi kutsitsa, chogwirizira, chowotcha, makina oyendetsa madzi amadzimadzi. arc ng'anjo transformer ndi zipangizo zosiyanasiyana zamagetsi
Malinga ndi mawonekedwe a ng'anjo ya ng'anjo yomizidwa pansi pamadzi, 70% ya ng'anjo ya arc imapangidwa ndi kachitidwe kakang'ono ka maukonde, ndipo kuwonongeka kwa ng'anjo yomizidwa m'madzi kumawonetsedwa m'chithunzi pansipa.

Poyerekeza ndi chiwongola dzanja champhamvu kwambiri, ubwino wa chipukuta misozi chochepa kwambiri umasonyezedwa m'zinthu zotsatirazi kuwonjezera pa kukonza mphamvu yamagetsi:
(1) Sinthani kuchuluka kwa magwiritsidwe ntchito a ma transfoma ndi mizere yapamwamba kwambiri, ndikuwonjezera mphamvu yolowera yosungunuka.Pakusungunula kwa arc, kupangidwa kwa mphamvu zowonongeka kumayambitsidwa ndi arc current.Malo olipira amapititsidwa patsogolo ku netiweki yaifupi, ndipo maukonde ambiri amfupi amalipidwa kwanuko.Kugwiritsa ntchito mphamvu kwamphamvu, onjezerani mphamvu yamagetsi yamagetsi, onjezerani kutulutsa kwa thiransifoma, ndikuwonjezera mphamvu yolumikizira yosungunulira.Mphamvu yosungunuka ya zinthuzo ndi ntchito yamagetsi a electrode ndi kukana kwenikweni kwa zinthu, zomwe zingathe kufotokozedwa ngati P = U 2 / Z zakuthupi.Chifukwa cha kusintha kwa mphamvu ya thiransifoma, mphamvu yowonjezera ya thiransifoma ku ng'anjo ikuwonjezeka, kuti azindikire kuwonjezeka kwa kupanga ndi kuchepetsa kugwiritsidwa ntchito.
(2) Malipiro osagwirizana kuti apititse patsogolo mikhalidwe yamphamvu ndi yofooka ya magawo atatu.Popeza masanjidwe a magawo atatu afupikitsa maukonde ndi thupi la ng'anjo ndi zida za ng'anjo nthawi zonse zimakhala zosagwirizana, madontho osiyanasiyana amagetsi ndi mphamvu zosiyanasiyana za magawo atatuwa amatsogolera ku magawo amphamvu komanso ofooka.kupanga gawo.Kulumikizana kofanana kwa gawo limodzi kumatengera kubwezeredwa kwamphamvu kwamphamvu, mphamvu yolipirira gawo lililonse imasinthidwa momveka bwino, kachulukidwe ka mphamvu ya ng'anjo ya ng'anjo ndi kufanana kwa phindu kumapangidwa bwino, mphamvu yogwira ntchito ya ma elekitirodi agawo atatu imagwirizana, magetsi a electrode ndi oyenerera, ndipo chakudya chamagulu atatu chimakhala chokwanira, kuwongolera magawo atatu Magawo amphamvu ndi ofooka a magawowa amatha kukwaniritsa cholinga chowonjezera kupanga ndi kuchepetsa kumwa.Panthawi imodzimodziyo, ikhoza kupititsa patsogolo zochitika zosagwirizana ndi magawo atatuwa, kukonza malo ogwirira ntchito a ng'anjo, ndikutalikitsa moyo wautumiki wa ng'anjo.
(3) Kuchepetsa ma harmonics apamwamba, kuchepetsa kuvulaza kwa ma harmonics ku zipangizo zonse zamagetsi, ndikuchepetsanso kuwonongeka kwa ma transformer ndi maukonde.
(4) Mphamvu yamagetsi yasinthidwa.Chifukwa chake, mayunitsi ena atengera njira zolipirira mphamvu zokhazikika kumapeto kwamagetsi otsika kuti athetse mavuto omwe ali pamwambawa.Kulipira kumapeto kwa gridi yaifupi kumatha kupititsa patsogolo mphamvu yamagetsi amtundu waufupi komanso kuchepetsa kugwiritsa ntchito mphamvu.Kuchuluka kwa mphamvu yogwiritsira ntchito mphamvu komanso kusalinganika kwa netiweki yaifupi kumbali yotsika ya thiransifoma ya ng'anjo, poganizira kusintha kwamphamvu kwa mphamvu yamagetsi ndikugwiritsa ntchito kusintha kwaukadaulo kwa chipukuta misozi champhamvu pamalopo, ndizodalirika mwaukadaulo. ndi okhwima, ndi kuyankhula mwachuma, zolowetsa ndi zotuluka zimayenderana mwachindunji.Pa mbali yotsika ya ng'anjo ya arc yomwe ili pansi pamadzi, mphamvu yowonongeka pamalopo imayendetsedwa chifukwa cha kugwiritsira ntchito mphamvu kwafupipafupi komanso zochitika zitatu zosagwirizana ndi kutalika kosagwirizana, kaya zikuwongolera mphamvu, kuyamwa. ma harmonics, kapena kuonjezera kupanga ndi kuchepetsa kumwa.Onse ali ndi ubwino wosayerekezeka wa chipukuta misozi champhamvu chamagetsi.Komabe, chifukwa cha kuchuluka kwa masiwichi osinthika muukadaulo wosinthira chipukuta misozi (monga kugwiritsa ntchito AC contactor switching), mtengo wosinthira masiwichi ndi wokwera, ndipo nthawi yomweyo, chifukwa cha malo ogwirira ntchito ovuta, moyo wautumiki ndi okhudzidwa kwambiri.Moyo wautumiki wamalipiro otsika-voltage ndi kusintha kwachikhalidwe ndizovuta kupitilira chaka chimodzi, chifukwa chake zimabweretsa kukonzanso kwakukulu kubizinesi, ndipo nthawi yobwezeretsa ndalama imatalikitsidwa.Chifukwa cha kukwera mtengo kotsatira kukonzanso, phindu lonse silili labwino.

Magawo aukadaulo

● Magawo atatu amalipidwa padera kuti achepetse kusagwirizana kwa magawo atatu ndikuwonjezera bwino kupanga ndi kuchepetsa kudya.Sinthani bwino kwambiri kutsika kwamagetsi ndi kuponderezana kwamagetsi 3, 5, 7 kuipitsidwa kwamtundu wa harmonic ndikuzindikira kusintha kwaulere nthawi iliyonse.
●Kudalirika kosinthira ndikwambiri, ndipo nthawi zosinthira zosinthira popanda kulephera zimatha kufikira mamiliyoni angapo.Ndi kambirimbiri moyo wa masiwichi wamba.Chifukwa chakusintha kwa vacuum kwanthawi yayitali, kukana kwake ndikwabwino, ndipo kumatha kufika kambirimbiri kuposa momwe zimakhalira popanda kuwonongeka.Palibe inrush yapano mukalowetsa, palibe overvoltage ikadulidwa.
●Kudalirika kwakukulu, kopanda kukonza komanso osayang'aniridwa
●Mapangidwe apamwamba achitetezo osagwiritsa ntchito fusesi amapewa kuwonongeka kwa ma capacitor ndi ma vacuum contactors kwambiri.Kupititsa patsogolo kwambiri mphamvu yogwiritsira ntchito magetsi.
