Njengoko sonke sisazi, ngenxa yokhuseleko, i-voltage ephakathi kunye nephezulu ye-voltage yangoku kwizikhululo zokuvavanya i-transformer ininzi ibekwe kwiqonga phakathi kwe-medium transformer kunye ne-transformer evavanyiweyo. Ngenxa yokuba ubude beqonga buphakathi kwe-2-4m, akulula kakhulu ukutshintsha uluhlu loqhagamshelwano ukuze unyuke kwaye uhle eqongeni.

Kwiminyaka yakutshanje, kukho iindlela ezininzi zokusombulula le ngxaki kwishishini lasekhaya, elinganelisiyo

(1) I-transformer yangoku ihlukaniswe ngamacandelo angama-2-3 ngexesha lokuqala kunye namacandelo angama-3-4 okwesibini. Eyesibini inokutshintshwa ngokutshintsha itephu. Inciphisa inani lokutshintsha kanye, kodwa emva kwayo yonke into, kufuneka itshintshe umgca kunye nokucima iqonga kanye, oko kwandisa into engakhuselekanga kubasebenzi bovavanyo.

(2) Ingasetyenziswa njengesixhobo sokutshintsha itephu yombane esisiseko sombane. Umtshintshi kunye ne-transformer yangoku izimeleyo enye kwenye kwaye idibene nebar yobhedu. Ukutshintsha kwamandla ombane aphezulu kuneendleko eziphezulu, izinga eliphezulu lokungaphumeleli kunye nokuthembeka okulambathayo. Ukukhutshwa okuyingxenye kungaphezulu kwe-50pc. Akukho kukhutshwa ngokuyinxenye.

(3) Abanye abavelisi baye benza izixhobo zokudityaniswa kwe-transformer yangoku kunye nempompo yokutshintsha. Ijongeka icwecwe, kodwa uninzi lwazo lonakaliswe ngenxa yokungaphumeleli kokutshintsha ngexesha lewaranti, okukhokelela ekumisweni kwemveliso.

Kwiminyaka yakutshanje, inkampani yethu iphuhlise uhlobo olutsha lwe-transformer yangoku ngokweemfuno zabasebenzisi bamanye amazwe

(1) Ngokupheleleyo kuluhlu lwesibini lokutshintsha, ekutshintsheni komthwalo, kwisigxina sokulawula umbane wesibini, kukulungele kakhulu ukusebenzisa, kwaye ugcina iswitshi ephambili ngesantya esiphezulu sokungaphumeleli.

(2) Ukuhambelana ne-analyzer yamandla: i-second rated current yi-1a, kungekhona i-5A. Ukusebenzisa i-analyzer yamandla, i-second rated current ingaba yi-1a. Ukuthatha i-W-3000 ye-analyzer yamandla njengomzekelo, eli phepha lichaza ukulungelelaniswa kolu hlobo lwe-transformer yangoku kunye ne-analyzer yamandla: i-channel yangoku ye-W-3000 yokuhlaziya amandla ineendlela ezimbini ezinkulu kunye ezincinci, kwaye i-channel yangoku encinci ikhethiwe. Ireyithi yangoku i-5mA, i-10mA, i-20mA, i-50mA, i-100mA, i-200mA, i-500mA, i-1A kunye ne-2a, kunye ne-9 gear iyonke, enokutshintsha ngokuzenzekelayo ngokufaka igalelo langoku. Iyakwazi ukulungiswa kwi-transformer yangoku ye-second 1a.

I-impedance yegalelo ye-channel encinci yangoku ye-W-3000 analyzer yamandla yi-0.5 Ω, kunye ne-impedance yesiphaluka sesibini i-0.3 Ω kakhulu, ngoko ke isiphumo esilinganisiweyo kufuneka sibe yi-0.6-0.8va.

(3) Ngenxa yokulinganiselwa kwezobuchwepheshe, uluhlu lwangoku olulinganisiweyo: IMAX / Imin ≤ 400, jonga iThebhile 1 kunye netafile 2 ngeenkcukacha.

(4) Iphutha: ngokunyuka koluhlu lwangoku, izinga lokuchaneka linyuka ukusuka kwi-0.2 ukuya kwi-0.01. Olu phawu lufanelekile nje kuvavanyo lwe-transformer. Njengoko sonke sisazi, ngenxa yokuba amandla ovavanyo lokungathwali mthwalo ngomyalelo we-0.2, i-transformer echanekileyo ephezulu ayifuni. Ngeli xesha, uluhlu oluphantsi lwe-50A nangaphantsi lusetyenziswa, kwaye ukuchaneka kwanele. Amandla ovavanyo lomthwalo aphantsi kakhulu (ukuya kwi-0.02-0.01), efuna ukuchaneka okuphezulu kwe-transformer. Ngeli xesha, icandelo eliphezulu le-100A nangaphezulu lisetyenzisiweyo, kwaye ukuchaneka kuphezulu kakhulu, ukuya kwi-0.01 kwinqanaba.

Xa i-IMAX / Imin ≤ 400, amanqanaba okuchaneka kwemilinganiselo eyahlukeneyo yangoku iboniswa kwiThebhile 1 kunye netheyibhile 2.

Siyazi ukuba ifomula yempazamo yokulinganisa ilahleko ye-transformer: Δ P% = 0.0291 δ TG φ% (1) Apho u-δ uphi umahluko (iyunithi: umzuzu) φ yomahluko we-engile phakathi kwe-engile yangoku kunye ne-voltage eguquguqukayo yi-angle factor factor ngexesha uvavanyo. Uluhlu lwangoku oluncinci luyi-5 / 1a-50 / 1a, eyona nto isetyenziselwa uvavanyo olungenamthwalo. I-Cos φ imalunga ne-0.2 xa kungekho mthwalo wovavanyo, oko kukuthi, i-TG φ yi-1.9. Umahluko omkhulu we-angular kwinqanaba eliphantsi le-0.2 ngu-± 10. I-voltage ehambelanayo ye-voltage transformer ingasetyenziswa njengenqanaba le-0.01, umahluko omkhulu we-angle ngu-± 0.3, kwaye umahluko omkhulu δ phakathi kwabo ngu-± 10.3. Ixabiso lifakwe kwifomula (1) Δ P% =0.0291 × (± 10.3,) × 1.9% = ± 0.57%, eyona mpazamo inkulu yeklasi 0.2. Ukuba i-0.1 gear isetyenzisiweyo, impazamo iseyisiqingatha, ekufuneka kuthiwa ichanekile kakhulu. Umlinganiselo wangoku osetyenziswayo kuvavanyo lomthwalo ungaphezulu kwe-100/1a, kwaye izinga lokuchaneka liyi-0.01. Umzekelo, i-35/10kv, i-3150kva i-transformer, ireyithingi yangoku kwicala le-35kV yi-52A, kunye ne-100/1a yegiya iya kukhethwa. 657ed23jst

Iindleko zale mveliso zingaphantsi kwexabiso le-transformer yangoku kunye nokutshintsha kwayo itephu yoluhlu oluphambili lokutshintsha. Onke amanqanaba ombane angasetyenziswa. Le teknoloji isekwe kwinguqulelo entsha ye-electromagnetic transformer yangoku ngokwayo, endaweni yokusebenzisa iamplifier yombane ukutshintsha uluhlu okwesibini, njengenkampani yaseSwitzerland ihaefely trench. Lo mzekelo ungowokuqala emhlabeni, imveliso ekhethekileyo, kwaye abanye abayi. Xa kuthelekiswa nehaefield, iingenelo zesiguquli sethu sangoku silandelayo:

(1) Ukusebenza kweendleko eziphezulu. Uvavanyo lwe-transformer lunokuthi luqhutywe kuluhlu lwesibini olukude, kunye neendleko malunga ne-1/10 yaseSwitzerland.

(2) Ukuthembeka okuphezulu. Ngaphandle kweamplifier yombane, ukuthembeka okuphezulu. Isixhobo sombane sonakaliswa lula ngamandla ombane kwindawo yelabhoratri yombane ophezulu. Ukuba yonakele, inokuthunyelwa kuphela eSwitzerland ukuze ilungiswe, engenakulungiswa eChina. Abasebenzisi basekhaya be-transformer yangoku entsha baboniswe kolu luhlu lulandelayo:
