Chiridzwa Chazvino Chachinja

Sezvo isu tese tichiziva, nekuda kwekuchengetedza, epakati uye akakwira voltage ezvino matransformer mu transformer test station anonyanya kuiswa pachikuva pakati pepakati transformer uye yakaedzwa transformer. Nekuti kureba kwepuratifomu kuri pakati pe2-4m, hazvina kunaka kuti uchinje nemaoko renji yekubatanidza kuenda kumusoro nekudzika papuratifomu.

Mumakore achangopfuura, kune nzira dzinoverengeka dzekugadzirisa dambudziko iri muindasitiri yemumba, izvo zvisingagutsi

(1) Ikozvino transformer yakakamurwa kuva 2-3 zvikamu panguva yekutanga uye 3-4 zvikamu panguva yechipiri. Yechipiri inogona kuchinjwa netap chenger. Inoderedza nhamba yekuchinja kamwe chete, asi shure kwezvose, inofanira kuchinja mutsara uye kubva papuratifomu kamwe chete, izvo zvinowedzera chinhu chisina kuchengeteka kune vashandi vekuedza.

(2) Inogona kushandiswa semagetsi ekutanga akakwira voltage tap shanduko. Iyo switch uye yazvino transformer yakazvimirira kubva kune imwe neimwe uye yakabatana nemhangura bar. High voltage switch ine mutengo wakakwira, mwero wekutadza kwakanyanya uye kusavimbika zvakanaka. Kuburitswa kwechidimbu kuri pamusoro pe50pc. Hapana chidimbu chinobuda.

(3) Vamwe vagadziri vakagadzira michina yekubatanidza yeazvino transformer uye tap shanduko. Inotaridzika compact, asi mazhinji acho akakuvadzwa nekuda kwekutadza kwekuchinja panguva yewaranti, zvichikonzera kumira kwekugadzira.

Mumakore achangopfuura, kambani yedu yakagadzira mhando nyowani yezvino transformer zvinoenderana nezvinodiwa nevashandisi vekunze

(1) Yakazara muchikamu chechipiri chekuchinja, pakuchinja kwemutoro, mune yechipiri magetsi ekudzora switching, iri nyore kushandisa, uye inochengetedza yekutanga switch ine yakanyanya kutadza mwero.

(2) Kuenderana nemagetsi analyzer: yechipiri yakayerwa ikozvino ndeye 1a, kwete 5A. Uchishandisa simba analyzer, yechipiri yakayerwa ikozvino inogona kuve 1a. Tichitora W-3000 simba analyzer semuenzaniso, bepa rino rinotsanangura kuchinjika kwemhando iyi yezvino transformer uye simba analyzer: chiteshi chezvino cheW-3000 simba analyzer chine maviri makuru uye madiki chiteshi, uye diki ikozvino chiteshi inosarudzwa. Iyo yakayerwa ikozvino 5mA, 10mA, 20mA, 50mA, 100mA, 200mA, 500mA, 1A uye 2a, ine 9 magiya akazara, ayo anogona kuchinjika otomatiki neinopinza ikozvino. Inogona kuchinjirwa kune yazvino transformer yechipiri 1a.

Iyo yekupinza impedance yediki ikozvino chiteshi cheW-3000 simba analyzer ndeye 0.5 Ω, uye yechipiri dunhu impedance ndeye 0.3 Ω zvakanyanya, saka iyo yakatemerwa inobuda inofanira kunge iri 0.6-0.8va.

(3) Nekuda kwezvisingakwanisi tekinoroji, iyo yakayerwa yazvino renji: IMAX / Imin ≤ 400, ona Tafura 1 uye tafura 2 kuti uwane ruzivo.

(4) Kukanganisa: nekuwedzera kwehuwandu hwemazuva ano, chiyero chechokwadi chinowedzera kubva ku0.2 kusvika ku0. Ichi chimiro chakangokodzera bvunzo yetransformer. Sezvo isu tese tinoziva, nekuti iyo simba chinhu cheye-yeye-yeyedzo chiri muhurongwa hwe0.2, yakakwirira-chaiyo transformer haidiwi. Panguva ino, iyo yakaderera ye50A uye pasi inoshandiswa, uye kunyatsokwana kwakakwana. Iyo simba chinhu chemutoro bvunzo yakaderera kwazvo (kusvika 0.02-0.01), iyo inoda kururamisa kwepamusoro kweshanduko. Panguva ino, chikamu chepamusoro che 100A uye pamusoro chinoshandiswa, uye kururamisa kwakanyanya kwazvo, kusvika ku 0.01 level.

Kana IMAX / Imin ≤ 400, chiyero chechokwadi chezvikamu zvakasiyana zvazvino zvinoratidzwa muTafura 1 uye tafura 2.

Tinoziva kuti fomula yekuyera kurasikirwa kwekuyera kukanganisa: Δ P% = 0.0291 δ TG φ% (1) Ipi δ musiyano (yuniti: miniti) φ yemusiyano wekona pakati pezvino transformer uye voltage transformer ndiyo simba factor angle panguva. bvunzo. Iyo mhando yediki yazvino ndeye 5 / 1a-50 / 1a, iyo inonyanya kushandiswa pasina-mutoro bvunzo. Cos φ inenge 0.2 kana pasina-mutoro bvunzo, kureva, TG φ iri 1.9. Musiyano mukuru weangular weyero yakaderera 0.2 ndeye ± 10. Iyo inofananidzwa voltage transformer inogona kushandiswa seyero 0.01, iyo yakakura angle musiyano ndeye ± 0.3, uye yakakura musiyano δ pakati pavo ± 10.3. Kukosha kunotsiviwa mufomula (1) Δ P% =0.0291 × (± 10.3,) × 1.9% = ± 0.57%, iyo ndiyo kukanganisa kukuru kwekirasi 0.2. Kana iyo 0.1 gear yakashandiswa, kukanganisa kuchiri hafu, iyo inofanira kunzi yakarurama kwazvo. Chiyero chazvino chinoshandiswa mukuyedzwa kwemutoro chiri pamusoro pe100/1a, uye chiyero chechokwadi chiri 0.01. Semuenzaniso, 35/10kv, 3150kva transformer, yakayerwa ikozvino pa35kV side i52A, uye 100/1a giya richasarudzwa. 657ed23jst

Mutengo wechigadzirwa ichi wakaderera pane huwandu hweiyozvino transformer uye yayo yepombi yekuchinja yeprimary switching renji. Ese voltage mazinga anogona kushandiswa. Iyi tekinoroji yakavakirwa pashanduko yekuvandudza yemagetsi azvino transformer pachayo, pane kushandisa magetsi amplifier kushandura renji kechipiri, sekambani yeSwitzerland haefely trench. Iyi modhi ndiyo yekutanga munyika, yakasarudzika kugadzirwa, uye vamwe havaite. Kuenzaniswa nehaefield, zvakanakira zveshanduro yedu yazvino ndeiyi:

(1) Kushanda kwemari yakakwirira. Iyo bvunzo yetransformer inogona zvakare kuitwa mune yechipiri kure kure renji switch, nemutengo ungangoita 1/10 yeSwitzerland.

(2) Kuvimbika kwepamusoro. Pasina magetsi amplifier, yakakwirira kuvimbika. Iyo yemagetsi midziyo inokuvadzwa nyore nemagetsi munzvimbo yakakwira voltage laboratory. Kana ikakuvadzwa, inogona kutumirwa kuSwitzerland kunogadziriswa, iyo isingagoni kugadziriswa muChina. Vashandisi vepamusha veshanduko nyowani yazvino vanoratidzwa patafura inotevera:
