Njengoba sonke sazi, ngenxa yokuphepha, ama-voltage aphakathi nendawo naphezulu eziteshini zokuhlola i-transformer abekwa kakhulu endaweni yesikhulumi phakathi kwe-medium transformer kanye ne-transformer ehloliwe. Ngenxa yokuthi ubude beplathifomu buphakathi kuka-2-4m, akulula kakhulu ukushintsha mathupha ububanzi bokuxhumana ukuze wehle uphinde wehle endaweni.

Eminyakeni yamuva, kunezindlela eziningana zokuxazulula le nkinga embonini yasekhaya, engagculisi

(1) I-transformer yamanje ihlukaniswe ngezigaba ezingu-2-3 ngesikhathi sokuqala kanye nezigaba ezingu-3-4 okwesibili. Okwesibili kungashintshwa ngokuthepha ukushintsha. Yehlisa inani lokushintshwa kanye, kodwa ngemuva kwakho konke, kufanele iguqule ulayini uvule futhi uvale ipulatifomu kanye, okwandisa isici esingaphephile kubasebenzi bokuhlola.

(2) Ingasetshenziswa njengenguquko kagesi eyisisekelo ephezulu kampompi kampompi. I-switch kanye ne-transformer yamanje izimele komunye nomunye futhi ixhunywe nge-copper bar. Ukushintsha kwamandla kagesi aphezulu kunezindleko eziphezulu, izinga eliphezulu lokuhluleka kanye nokwethenjwa okuphansi. Ukukhishwa kwengxenye kungaphezu kwama-50pc. Akukho ukukhipha ingxenye.

(3) Abanye abakhiqizi benze okokusebenza kokuhlanganisa kwe-transformer yamanje kanye ne-tap change. Kubukeka kuhlangene, kodwa eziningi zazo zonakele ngenxa yokwehluleka kokushintsha ngesikhathi sewaranti, okuholela ekumisweni kokukhiqiza.

Eminyakeni yamuva, inkampani yethu ithuthukise uhlobo olusha lwe-transformer yamanje ngokwezidingo zabasebenzisi bangaphandle

(1) Ngokuphelele ebangeni lesibili lokushintsha, ekushintsheni komthwalo, ekushintsheni kokulawula ugesi kwesibili, kulula kakhulu ukukusebenzisa, futhi kulondoloza iswishi eyinhloko ngezinga eliphezulu lokuhluleka.

(2) Ukuhambisana nesihlaziyi samandla: isilinganiso sesibili samanje singu-1a, hhayi u-5A. Ngokusebenzisa isihlaziyi samandla, isilinganiso sesibili samanje singaba ngu-1a. Ukuthatha i-W-3000 power analyzer njengesibonelo, leli phepha lichaza ukuguquguquka kwalolu hlobo lwe-transformer yamanje kanye ne-analyzer yamandla: isiteshi samanje se-W-3000 sokuhlaziya amandla sineziteshi ezimbili ezinkulu nezincane, futhi isiteshi samanje esincane sikhethiwe. Isilinganiso samanje singu-5mA, 10mA, 20mA, 50mA, 100mA, 200mA, 500mA, 1A kanye no-2a, namagiya angu-9 esewonke, angashintsha ngokuzenzakalelayo ngokufaka kwamanje. Ingashintshwa ku-transformer yamanje ye-secondary 1a.

I-impedance yokufaka yesiteshi esincane samanje se-W-3000 sokuhlaziya amandla ngu-0.5 Ω, futhi i-impedance yesifunda yesibili ngu-0.3 Ω okungenani, ngakho-ke okukhiphayo okulinganiselwe kufanele kube ngu-0.6-0.8va.

(3) Ngenxa yemikhawulo yezobuchwepheshe, uhla lwamanje olulinganiselwe: IMAX / Imin ≤ 400, bheka Ithebula 1 kanye nethebula 2 ukuze uthole imininingwane.

(4) Iphutha: ngokukhula kobubanzi bamanje, izinga lokunemba liyakhuphuka lisuka ku-0.2 liye ku-0.01. Lesi sici silungele ukuhlolwa kwe-transformer. Njengoba sonke sazi, ngoba isici samandla sokuhlolwa okungekho umthwalo silandelana ngo-0.2, i-transformer enembayo ephezulu ayidingeki. Ngalesi sikhathi, ububanzi obuphansi be-50A nangaphansi busetshenziswa, futhi ukunemba kwanele. Isici samandla sokuhlolwa komthwalo siphansi kakhulu (kufika ku-0.02-0.01), esidinga ukunemba okuphezulu kwe-transformer. Ngalesi sikhathi, isigaba esiphezulu sebanga le-100A nangaphezulu sisetshenziswa, futhi ukunemba kuphezulu kakhulu, kuze kufike ezingeni le-0.01.

Uma i-IMAX / Imin ≤ 400, amazinga okunemba ezilinganiso zamanje ezihlukahlukene aboniswa kuThebula 1 nakuthebula 2

Siyazi ukuthi ifomula yephutha lesilinganiso sokulahlekelwa kwe-transformer: Δ P% = 0.0291 δ TG φ% (1) Lapho u-δ ekhona umehluko (iyunithi: iminithi) φ yomehluko we-engeli phakathi kwesiguquli samanje nesiguquli se-voltage i-engeli yesici samandla ngesikhathi ukuhlolwa. Uhlu lwamanje oluncane luyi-5 / 1a-50 / 1a, olusetshenziselwa kakhulu ukuhlola okungekho umthwalo. I-Cos φ icishe ibe ngu-0.2 lapho ukuhlolwa okungenamthwalo, okungukuthi, i-TG φ ingu-1.9. Umehluko omkhulu we-angular wezinga eliphansi kakhulu elingu-0.2 ngu-± 10. I-voltage transformer efanisiwe ingasetshenziswa njengezinga elingu-0.01, umehluko omkhulu we-engeli ngu-± 0.3, futhi umehluko omkhulu δ phakathi kwawo ngu-± 10.3. Inani lithathelwa indawo ifomula (1) Δ P% =0.0291 × (± 10.3,) × 1.9% = ± 0.57%, okuyiphutha elikhulu lesigaba 0.2. Uma kusetshenziswa igiya elingu-0.1 iphutha lisewuhhafu, okumele kuthiwe linemba kakhulu. Isilinganiso samanje esisetshenziswa ekuhlolweni komthwalo singaphezu kuka-100/1a, futhi izinga lokunemba lingu-0.01. Isibonelo, i-35/10kv, i-3150kva transformer, ekalwe okwamanje ku-35kV ohlangothini i-52A, futhi igiya elingu-100/1a lizokhethwa. 657ed23jst

Izindleko zalo mkhiqizo zingaphansi kwesamba se-transformer yamanje kanye nesiguquli saso sompompi sebanga lokushintsha eliyisisekelo. Wonke amazinga kagesi angasetshenziswa. Lobu buchwepheshe busekelwe enguqukweni emisha ye-electromagnetic current transformer ngokwayo, esikhundleni sokusebenzisa iamplifier kagesi ukushintsha ububanzi okwesibili, njengomsele wenkampani yaseSwitzerland i-haefely. Le modeli ingeyokuqala emhlabeni, ukukhiqizwa okukhethekile, kanti abanye ngeke. Uma kuqhathaniswa ne-haefield, izinzuzo ze-transformer yethu yamanje zimi kanje:

(1) Ukusebenza kwezindleko eziphezulu. Ukuhlolwa kwe-transformer kungenziwa futhi ekushintsheni kwebanga lesibili elikude, ngezindleko ezingaba ngu-1/10 waseSwitzerland.

(2) Ukwethembeka okuphezulu. Ngaphandle kwe-amplifier kagesi, ukwethembeka okuphezulu. Izinto zikagesi zonakaliswa kalula amandla kagesi endaweni yaselabhorethri yamandla kagesi aphezulu. Uma yonakele, ingathunyelwa kuphela eSwitzerland ukuze ilungiswe, engakwazi ukulungiswa eChina. Abasebenzisi basekhaya be-transformer yamanje entsha baboniswa kuthebula elilandelayo:
