Chida Chamakono Transformer

Monga tonse tikudziwira, chifukwa cha chitetezo, zosintha zapakatikati ndi zapamwamba zamagetsi zamakono m'malo oyesera a transformer nthawi zambiri zimayikidwa papulatifomu pakati pa thiransifoma yapakatikati ndi chosinthira choyesedwa. Chifukwa kutalika kwa nsanja kuli pakati pa 2-4m, ndikovuta kwambiri kusintha pamanja mawonekedwe olumikizira kuti apite mmwamba ndi pansi.

M'zaka zaposachedwa, pali njira zingapo zothetsera vutoli m'makampani apakhomo, zomwe sizokhutiritsa

(1) Transformer yamakono imagawidwa m'magawo a 2-3 nthawi yoyamba ndi magawo 3-4 panthawi yachiwiri. Yachiwiri ikhoza kusinthidwa ndi chosinthira chapampopi. Amachepetsa chiwerengero cha kusintha kamodzi, koma pambuyo pake, amayenera kusintha mzere ndi kuchoka pa nsanja kamodzi, zomwe zimawonjezera chinthu chosatetezeka kwa ogwira ntchito zoyesa.

(2) Itha kugwiritsidwa ntchito ngati chosinthira chamagetsi chachikulu chamagetsi chamagetsi. Chosinthira ndi thiransifoma yamakono ndizodziyimira pawokha ndipo zimalumikizidwa ndi bar yamkuwa. Kusintha kwamphamvu kwamagetsi kumakhala ndi mtengo wokwera, kulephera kwakukulu komanso kusadalirika kodalirika. Kutulutsa pang'ono kuli pamwamba pa 50pc. Palibe kutulutsa pang'ono.

(3) Opanga ena apanga zida zophatikizira za thiransifoma yamakono ndi tap chosinthira. Zikuwoneka ngati zazing'ono, koma zambiri zimawonongeka chifukwa cha kulephera kwa kusinthana panthawi ya chitsimikizo, zomwe zimapangitsa kuyimitsidwa.

M'zaka zaposachedwapa, kampani yathu yapanga mtundu watsopano wa thiransifoma wamakono malinga ndi zofunikira za ogwiritsa ntchito akunja

(1) Kwathunthu mumtundu wachiwiri wosinthira, pakusintha kwa katundu, pakusintha kwamagetsi kwachiwiri, ndikosavuta kugwiritsa ntchito, ndikusunga chosinthira choyambirira ndi kulephera kwakukulu.

(2) Kugwirizana ndi mphamvu analyzer: yachiwiri oveteredwa panopa ndi 1a, osati 5A. Pogwiritsa ntchito chowunikira mphamvu, chowerengera chachiwiri chikhoza kukhala 1a. Kutengera chitsanzo cha W-3000 mphamvu analyzer, pepala ili likufotokoza kusinthika kwa mtundu uwu wa thiransifoma yamakono ndi magetsi analyzer: njira yamakono ya W-3000 mphamvu analyzer ali ndi njira ziwiri zazikulu ndi zazing'ono, ndipo njira yaing'ono yamakono imasankhidwa. Zomwe zidavoteledwa ndi 5mA, 10mA, 20mA, 50mA, 100mA, 200mA, 500mA, 1A ndi 2a, zokhala ndi magiya 9 onse, omwe amatha kusuntha zokha ndi zomwe zidalowa. Itha kusinthidwa kukhala thiransifoma yamakono ya sekondale 1a.

Kulowetsedwa kwa njira yaying'ono yamakono ya W-3000 analyzer mphamvu ndi 0.5 Ω, ndipo yachiwiri dera impedance ndi 0.3 Ω kwambiri, kotero oveteredwa linanena bungwe ayenera kukhala 0.6-0.8va.

(3) Chifukwa cha zolephera zaukadaulo, kuchuluka kwazomwe zidavotera: IMAX / Imin ≤ 400, onani Table 1 ndi tebulo 2 kuti mumve zambiri.

(4) Cholakwika: ndi kuchuluka kwazomwe zikuchitika, mulingo wolondola ukuwonjezeka kuchokera ku 0.2 mpaka 0.01. Izi ndizoyenera kuyesa kwa transformer. Monga tonse tikudziwira, chifukwa mphamvu ya mayeso osanyamula katundu ili mu dongosolo la 0.2, thiransifoma yolondola kwambiri sifunikira. Panthawiyi, kutsika kwa 50A ndi pansi kumagwiritsidwa ntchito, ndipo kulondola ndikokwanira. Mphamvu yoyesera yolemetsa ndiyotsika kwambiri (mpaka 0.02-0.01), yomwe imafuna kulondola kwakukulu kwa thiransifoma. Panthawiyi, gawo lapamwamba la 100A ndi pamwamba likugwiritsidwa ntchito, ndipo kulondola kuli kwakukulu kwambiri, mpaka 0.01 mlingo.

Pamene IMAX / Imin ≤ 400, milingo yolondola yamitundu yosiyanasiyana yamakono ikuwonetsedwa mu Table 1 ndi tebulo 2.

Tikudziwa kuti njira yoyezera kutayika kwa thiransifoma cholakwika: Δ P% = 0.0291 δ TG φ% (1) Pomwe δ pali kusiyana (yunitsi: miniti) φ ya kusiyana kwa ngodya pakati pa thiransifoma yamakono ndi thiransifoma yamagetsi ndi mphamvu yamagetsi panthawi mayeso. Mitundu yaying'ono yamakono ndi 5 / 1a-50 / 1a, yomwe imagwiritsidwa ntchito kwambiri poyesa mayeso osanyamula. Cos φ ili pafupi 0.2 pamene palibe-load test, ndiye kuti, TG φ ndi 1.9. Kusiyana kwakukulu kwa angular kwa mlingo wotsika kwambiri wa 0.2 ndi ± 10. Transformer yofananira ingagwiritsidwe ntchito ngati mlingo 0.01, kusiyana kwakukulu kwa ngodya ndi ± 0.3, ndipo kusiyana kwakukulu δ pakati pawo ndi ± 10.3. Mtengowo umalowetsedwa mu chilinganizo (1) Δ P% =0.0291 × (± 10.3,) × 1.9% = ± 0.57%, chomwe ndi cholakwika chachikulu cha kalasi 0.2. Ngati zida za 0.1 zikugwiritsidwa ntchito, cholakwikacho chikadali theka, chomwe chiyenera kunenedwa kuti ndicholondola kwambiri. Chiyerekezo chapano chomwe chimagwiritsidwa ntchito poyesa katundu chili pamwamba pa 100/1a, ndipo mulingo wolondola ndi 0.01. Mwachitsanzo, 35/10kv, 3150kva thiransifoma, yovotera pa 35kV mbali ndi 52A, ndipo giya 100/1a idzasankhidwa. 657ed23jst

Mtengo wa mankhwalawa ndi wocheperako poyerekeza ndi kuchuluka kwa thiransifoma yamakono komanso chosinthira chake chosinthira choyambirira. Ma voltages onse angagwiritsidwe ntchito. Ukadaulo uwu wakhazikika pakusintha kwakusintha kwa chosinthira chamagetsi chamagetsi chokha, m'malo mogwiritsa ntchito amplifier yamagetsi kusinthanso kachiŵiri, monga ngalande ya kampani yaku Swiss haefely. Chitsanzo ichi ndi choyamba padziko lapansi, kupanga kwapadera, ndipo ena sadzatero. Poyerekeza ndi haefield, ubwino wa thiransifoma yathu yatsopano ndi motere:

(1) Kuchita zotsika mtengo. Mayeso a thiransifoma amathanso kuchitidwa pakusintha kwachiwiri kwakutali, ndi mtengo wa 1/10 waku Switzerland.

(2) Kudalirika kwambiri. Popanda amplifier zamagetsi, kudalirika kwakukulu. Zida zamagetsi zimawonongeka mosavuta ndi magetsi m'malo a labotale apamwamba kwambiri. Ngati yawonongeka, imatha kutumizidwa ku Switzerland kuti ikakonzedwe, yomwe siingathe kukonzedwanso ku China. Ogwiritsa ntchito m'nyumba a transformer yatsopano akuwonetsedwa patebulo ili:
