Dab tsi yog cov hauv paus ntsiab lus rau kev siv tam sim no transformers?

Kuv yuav piav qhia los ntawm ntau qhov ntev: winding division, load matching, transient yam ntxwv, circuit configuration, thiab kev khiav hauj lwm thiab kev tswj xyuas:

Metering-qib windings yuav tsum xyuas kom meej tias qhov sib xyaw ua yuam kev thiab theem ua yuam kev raws li qhov ntsuas tam sim no ua tau raws li qhov yuav tsum tau ua kom raug ntsuas qhov tseeb, thiab lawv qhov tseem ceeb sib nqus flux ntom ntom yog tsim los kuj qis. Kev tiv thaiv-qib windings tsom rau cov yam ntxwv hloov pauv hloov pauv thiab qhov cuam tshuam qhov hluav taws xob nyob rau hauv luv luv- lub sijhawm tam sim no. Cov txheej txheem tseem ceeb thiab excitation tsis ntawm ob yog txawv; Nws yog nruj me ntsis txwv tsis pub mus txuas metering windings rau kev tiv thaiv circuits, thiab tsis muaj peev xwm tiv thaiv windings yuav siv tau rau cov metering meej. Rau multi-kais, multi-winding tam sim no transformers, lub cev thaiv ntawm txhua lub voj voog yuav tsum tau sib cais kom tsis txhob cuam tshuam electromagnetic coupling.

Ua ntej, nws yuav tsum paub qhov txawv ntawm qhov ntsuas impedance thiab qhov ua haujlwm impedance. Tag nrho cov impedance ntawm lub thib ob Circuit Court, xws li meters, cables, adapter terminals, thiab connectors, yuav tsum tsis tsuas yog tsawg tshaj li qhov ntsuas load impedance, tab sis kuj cable voltage poob yuav tsum tau xam raws li nyob rau hauv lub installation nrug. Rau qhov ntev - kab hluav taws xob nyob deb, loj- ntu txuas txuas txuas ntxiv yuav tsum raug xaiv, thiab kev tiv thaiv hluav taws xob yuav tsum tau tswj. Qhov thib ob, cov chav kawm sib txawv ntawm cov tam sim no transformers (CTs) sib haum rau cov khoom sib txawv. Precision metering CTs yuav tsum ua haujlwm li ntawm 25% mus rau 75% ntawm lawv cov khoom ntsuas; Tsis tshua muaj loads yuav ua rau kom lub kaum sab xis yuam kev thiab piv piv. Tsis tas li ntawd, thaum muaj ntau yam cuab yeej txuas nrog hauv cov koob, tag nrho cov load yuav tsum raug txheeb xyuas raws li lub hauv paus ntsiab lus ntawm impedance superposition; blindly txuas lwm pab kiag li lawm nyob rau hauv series yog txwv.

Thaum lub kaw lus tau ntsib nyob ze ntawm -kawg luv luv, rov qab, lossis hloov pauv tsis siv neeg, qhov tsim nyog TPS / TPY / TPZ hom tiv thaiv tam sim no transformer yuav tsum raug xaiv raws li luv luv -circuit tam sim no ntau yam thiab luv luv- lub sijhawm luv luv. Ordinary P-chav kawm CTs tsis tuaj yeem txwv tsis pub dhau lub sijhawm saturation, ua rau muaj kev ua haujlwm tsis zoo lossis tsis ua haujlwm. Nyob rau tib lub sijhawm, qhov ntsuas qhov tseeb txwv coefficient ntawm lub transformer yuav tsum raug kuaj xyuas kom ntseeg tau tias cov tub ntxhais tsis sib zog nqus nyob rau hauv qhov system qhov siab tshaj plaws luv luv -circuit tam sim no. Rau siab -voltage systems, dynamic stability thiab thermal stability tam sim no tsis yuav tsum tau kuaj xyuas kom haum rau thawj sab luv- Circuit Court cuam tshuam lub zog.

Cov chaw hauv av muaj cov kev cai tshwj xeeb: Rau cov khoom siv sab nraum zoov thiab siab -voltage switchgear, qhov chaw nruab nrab ntawm CT yuav tsum tau teeb tsa tib lub sijhawm ntawm ib qho -point grounding point ntawm chav tswj kev tiv thaiv vaj huam sib luag / metering vaj huam sib luag. Rov qab grounding rau ntawm lub txee lossis lub thawv davhlau ya nyob twg sab yog nruj me ntsis txwv tsis pub cuam tshuam los ntawm qhov sib txawv hauv av. Rau kev tiv thaiv kev sib txawv thiab kev tiv thaiv tsheb npav sib txawv, ntxiv rau cov pa hauv av, txoj hauv kev hauv av ntawm ob sab ntawm CTs ntawm ob sab yuav tsum ua kom zoo ib yam kom tsis txhob cuam tshuam tam sim no. Tsis tas li ntawd, disconnectable isolating keyboards thiab fuses yog nruj me ntsis txwv tsis pub nyob rau hauv lub thib ob circuits. Yog tias yuav tsum tau kuaj cov terminals ntxiv, cov kev sim ntsuas lub davhlau ya nyob twg uas muaj luv luv - Circuit Court muaj nuj nqi yuav tsum raug xaiv los xyuas kom meej tias lub voj voog luv luv -circuited thaum lub sij hawm tshem tawm thiab ntsuas ntsuas.

Ua ntej, rau kev xaiv tam sim no transformer, qhov kev ua haujlwm ib txwm ua haujlwm tam sim no yuav tsum ua kom poob qis hauv 40% ~ 100% ntawm CT's rated thawj tam sim no. Thaum lub load tsis tu ncua qis dua 20% ntawm qhov ntsuas tam sim no, nws raug nquahu kom xaiv qhov qis -load tus yam ntxwv ua kom zoo dua CT los txhim kho qhov tseeb hauv qab lub teeb. Rau cov kab hluav taws xob uas muaj qhov sib txawv heev, qhov dav - cov transformers tam sim no yuav tsum tau ua ntej. Thib ob, hauv kev ua haujlwm sib luag thiab ntau yam -circuit parallel scenarios, CTs nyob rau hauv tib pab pawg yuav tsum xyuas kom meej qhov kev hloov pauv zoo ib yam, qhov tseeb, thiab cov yam ntxwv zoo siab los tiv thaiv qhov tsis sib xws tam sim no. Thib peb, ib puag ncig adaptability yog qhov tseem ceeb. Nyob rau sab nraum zoov, siab -cov av noo, plua plav, thiab corrosive ib puag ncig, kev xaiv yuav tsum yog raws li kev tiv thaiv thiab rwb thaiv tsev theem, thiab cov hlau lead hauv nruab nrab yuav tsum tau tiv thaiv kom tsis txhob muaj qhov tsis zoo uas tshwm sim los ntawm rwb thaiv tsev degradation.

LVZW-35 tam sim no transformer yog ib qho sensor siv los ntsuas qhov tam sim no loj hauv 35kV system. Nws yog tsuas yog siv nyob rau hauv substations, hluav taws xob systems thiab hluav taws xob khoom. Lub transformer txais kev sib nqus core hom, uas yog tus cwj pwm los ntawm high linearity, muaj zog tiv thaiv - muaj peev xwm cuam tshuam, me me thiab cov qauv yooj yim.
