Zambiri za ogwiritsa ntchito
Kampani yoponya ma valve pachipata makamaka imapanga zinthu za valve.Zida zopangira zida za kampaniyi zikuphatikizanso ng'anjo yamagetsi ya 2-ton medium-frequency induction, yomwe imayendetsedwa ndi 2000 kVA (10KV/0.75 kVA) akatswiri opanga magetsi osinthira magetsi.Okonzeka ndi 2 capacitance makabati chipukuta misozi voliyumu 600 kVA, 1-tani wapakatikati pafupipafupi kupatsidwa mphamvu ng'anjo, 800 kVA (10KV/0.4KV) thiransifoma luso ndi akatswiri, ndi capacitance chipukuta nduna ndi buku la 300 kVA .Chithunzi cha dongosolo lamagetsi ndi motere:

Zomwe zimagwira ntchito
Mphamvu yowoneka ya ng'anjo yapakatikati yokhala ndi chosinthira cha 2000KVA ndi 700KVA-2100KVA, mphamvu yogwira ndi P=280KW-1930KW, katundu wokhazikika ndi Q=687KAR-830KAR, chinthu champhamvu ndi PF=0.4-0.92, ndi yomwe ikugwira ntchitoⅰ = 538 A-1660 A, mphamvu yowonekera ya ng'anjo yapakatikati yokhala ndi thiransifoma ya 800KVA ndi 200KVA-836KVA.Mphamvu yogwira ndi P=60KW-750KW, katundu wokhazikika ndi Q=190KAR-360KAR, mphamvu ndi PF=0.3-0.9, ndi panopa i=288 A-1200 A. Chifukwa capacitor compensation cabinet sangathe kuikidwa kugwira ntchito (malipiro amoto amalephera, pamene capacitor ikugwiritsidwa ntchito pamanja, phokoso la capacitor ndilosazolowereka, maulendo oyendetsa dera, capacitor amapakidwa, mafuta atayikira, osweka, ndipo sangathe kugwiritsidwa ntchito), mphamvu ya mwezi uliwonse. PF=0.78, ndipo chiwongola dzanja cha pamwezi chimasinthidwa kupitilira 32,000 yuan.

Kusanthula Mkhalidwe Wamagetsi
Katundu wamkulu wamagetsi apakatikati amagetsi owongolera ng'anjo yamagetsi ndi 6-pulse rectification.Zida zokonzanso zimasinthira AC kukhala DC pomwe ikupanga ma harmonics ambiri.Ma gwero amtundu wa harmonic amalowetsedwa mu gululi, ndipo kutsekeka kwa gululi kumapanga voteji ya harmonic, kuchititsa grid voteji Kupotoka kwamakono kumakhudza mphamvu yamagetsi ndi chitetezo cha ntchito, kumawonjezera kutayika kwa mzere ndi kuchepetsa mphamvu, ndikuwonjezera mphamvu.Banki yamphamvu yolipirirayo ikayamba kugwira ntchito, chifukwa mawonekedwe a banki a capacitor ndi ochepa, ma harmonic ambiri amalowetsedwa mu banki ya capacitor, ndipo kuchuluka kwa capacitive pano Kuwonjezeka kofulumira kumakhudza kwambiri moyo wake wautumiki.Komano, pamene harmonic capacitive zimachitikira banki capacitor ndi wofanana harmonic inductive zimachitikira dongosolo ndi mndandanda resonance zimachitika, harmonic panopa kwambiri anakulitsa (2-10 nthawi), chifukwa kutenthedwa ndi kuwonongeka kwa capacitor.Kuphatikiza apo, ma harmonics amapangitsa kuti mafunde a sinusoidal a DC asinthe, zomwe zimapangitsa kuti pakhale nsonga yamtundu wa sawtooth, zomwe zimakhala zosavuta kutulutsa pang'ono muzinthu zoteteza.Kutulutsa kwapang'onopang'ono kwa nthawi yayitali kumathandiziranso kukalamba kwa zinthu zoziziritsa kukhosi ndikupangitsa kuwonongeka kwa capacitor mosavuta.Chifukwa chake, capacitor reactive power compensation cabinet siyingagwiritsidwe ntchito polipira ng'anjo yapakatikati ya ng'anjo yapakatikati, ndipo chida cholipirira mphamvu chogwiritsa ntchito fyuluta chokhala ndi pulse current kupondereza chiyenera kusankhidwa.

Dongosolo la chithandizo chamalipiro amphamvu
Zolinga zaulamuliro
Mapangidwe a zida zolipirira zosefera amakwaniritsa zofunikira pakuponderezedwa kwa ma harmonic ndi kasamalidwe kamphamvu koletsa mphamvu.
Pansi pa machitidwe a 0.75KV ndi 0.4KV, zida zolipirira zosefera zitayikidwa, kugunda kwapano kumaponderezedwa, ndipo mphamvu yapakati pamwezi imaposa 0.95.Kulowetsa kwa lupu yamalipiro a fyuluta sikungapangitse kugunda kwapakatikati kapena kuchulukira kwamphamvu komanso kupitilira apo.

Malingaliro opangira
Malinga ndi momwe kampaniyo ilili, kampani yathu yapanga mndandanda watsatanetsatane wanthawi yayitali wa ng'anjo yamagetsi yogwiritsira ntchito mphamvu zolipirira zosefera.Ganizirani mozama za katundu wamagetsi ndi kuponderezedwa kwa harmonic, ndikuyika zosefera zolipirira mphamvu zotsika-voltage pansi pa voltage ya 0.75KV ndi 0.4KV thiransifoma ya kampaniyo kuti ipondereze ma harmonics, kubwezera mphamvu zotakataka, ndikuwongolera mphamvu yamagetsi.Pakugwira ntchito kwa ng'anjo yapakati pafupipafupi, chipangizo chowongolera chimapanga ma 6K + 1 ma harmonics, ndipo mndandanda wa Fourier umagwiritsidwa ntchito kuwola ndikusintha zomwe zilipo kuti apange ma harmonics 5 a 250HZ ndi ma harmonics 7 pamwamba pa 350HZ.Chifukwa chake, popanga chipukuta misozi chosagwira ntchito cha ng'anjo yafupipafupi, ziyenera kuwonetseredwa kuti gawo lanthambi lolipiridwa ndi fyuluta limalipira mphamvu yosagwira ntchito popondereza ma harmonics opitilira 250HZ ndi 350HZ, ndikuwonjezera mphamvu.

ntchito yopanga
Mphamvu yokwanira ya ng'anjo yapakatikati ya 2-ton yofanana ndi thiransifoma ya 2000 kVA imalipidwa kuchokera pa 0.78 mpaka 0.95.Chipangizo cholipirira zosefera chiyenera kukhala ndi mphamvu ya 820 kVA, ndipo chimasinthidwa kukhala magulu 6 a mphamvu, iliyonse yomwe imagwirizana ndi mapiritsi omwe ali pansi pamagetsi a thiransifoma kuti alipire.Mphamvu yosinthira magulu a kalasi ndi 60KVAR, yomwe imatha kukwaniritsa zofunikira zosiyanasiyana za ng'anjo yapakati pafupipafupi.Mphamvu yokwanira ya ng'anjo yapakatikati ya tani imodzi yofananira ndi thiransifoma ya 800 kVA imalipidwa kuchokera pa 0.78 mpaka pafupifupi 0.95.Zida zolipirira zosefera ziyenera kukhala ndi mphamvu ya 360 kVA, yomwe imatha kusinthidwa kukhala magulu 6 amphamvu, ndipo mphamvu yosinthira yosinthidwa ndi 50 kVA, yomwe imatha kukwaniritsa zofunikira zosiyanasiyana zamagetsi pang'anjo yapakati pafupipafupi.Mapangidwe amtunduwu amatsimikizira kwathunthu kuti mphamvu yosinthidwa ndiyokwera kuposa 0.95.
