Electronic Current Transformer

Lub hauv paus ntsiab lus ntawm tam sim no transformer yog raws li lub hauv paus ntsiab lus ntawm electromagnetic induction. Tam sim no transformer muaj ib tug kaw core thiab winding. Tus naj npawb ntawm cov lem nyob rau hauv thawj winding yog heev me me, thiab nws yog strung nyob rau hauv txoj kab tam sim no uas yuav tsum tau ntsuas, yog li nws feem ntau muaj tag nrho cov tam sim no ntws los ntawm txoj kab, thiab tus naj npawb ntawm lem nyob rau hauv lub thib ob winding kuj loj. , thiab nws txuas nrog rau hauv lub ntsuas ntsuas thiab lub voj kev tiv thaiv. Thaum lub transformer tam sim no ua haujlwm, nws lub voj thib ob yog ib txwm kaw, yog li lub impedance ntawm series coil ntawm lub ntsuas ntsuas thiab lub voj tiv thaiv me me heev. Lub xeev ua hauj lwm ntawm tam sim no transformer yog ze rau lub luv luv Circuit Court.

Txhawb kev kos duab customization

Raws li kev siv sib txawv, tam sim no transformers tuaj yeem muab faib ua ob pawg:

Ntsuas tam sim no transformer (los yog ntsuas winding ntawm tam sim no transformer): nyob rau hauv ib txwm ua hauj lwm tam sim no ntau yam, muab cov ntaub ntawv tam sim no ntawm daim phiaj fais fab rau cov ntsuas thiab ntsuas cov cuab yeej.

Kev tiv thaiv tam sim no transformer (los yog kev tiv thaiv winding ntawm tam sim no transformer): nyob rau hauv lub xeev ntawm lub hwj chim daim phiaj txhaum, muab kev tiv thaiv relay thiab lwm yam khoom siv nrog lub hwj chim daim phiaj tam sim no cov ntaub ntawv.

Cov kev cai tseem ceeb

Rated peev: Lub zog pom meej siv thaum cov ntsuas theem nrab tam sim no dhau los ntawm qhov ntsuas thib ob. Rated muaj peev xwm yuav qhia tau hais tias nyob rau hauv cov nqe lus ntawm lub zog VA, los yog nyob rau hauv cov nqe lus ntawm theem nrab rated load impedance Ω.

Primary rated tam sim no: Lub load tam sim no tso cai rau dhau los ntawm thawj winding ntawm tam sim no transformer. Thawj qhov ntsuas tam sim no ntawm lub tshuab hluav taws xob tam sim no rau lub zog hluav taws xob yog 5 ~ 25000A, thiab qhov tseeb tam sim no transformer rau cov cuab yeej ntsuas yog 0.1 ~ 50000A. Tam sim no transformer tuaj yeem khiav tau ntev ntawm qhov ntsuas tam sim no. Thaum lub load tam sim no tshaj qhov ntsuas tam sim no, nws yog hu ua overload. Lub sij hawm ntev overloading ntawm lub transformer tam sim no yuav hlawv lub winding los yog txo cov kev pab cuam lub neej.

Secondary tam sim no ntsuam xyuas: Thawj induced tam sim no yog tso cai los ntawm lub thib ob winding ntawm lub tam sim no transformer.

Rated tam sim no ratio (variable ratio): tus piv ntawm thawj rated tam sim no mus rau theem nrab rated tam sim no.

Rated voltage: Qhov siab tshaj plaws voltage uas thawj winding tuaj yeem tiv taus hauv av tau ntev (tus nqi zoo yog nyob rau hauv kV), uas yuav tsum tsis txhob qis dua qhov ntsuas theem voltage ntawm cov kab txuas. Qhov ntsuas hluav taws xob ntawm lub tshuab hluav taws xob tam sim no tau muab faib ua ntau theem xws li 0.5, 3,6,10,35,110,220,330,500 kV.

10% ntau yam: Qhov ntau yam ntawm cov thawj tam sim no rau tus nqi ntsuas thaum qhov kev ua yuam kev tam sim no ntawm qhov hloov pauv tam sim no yog -10% raws li qhov teev thib ob thiab cov khoom siv fais fab. Qhov 10% ntau yog ib qho kev qhia txog kev tiv thaiv relay.

Qib raug: qhia qib ntawm qhov kev hloov pauv qhov yuam kev (qhov sib piv thiab lub kaum sib txawv). Qhov tseeb theem ntawm lub transformer tam sim no tau muab faib ua {{0}}}001 ~ 1 ntau theem, thiab qhov tseeb tau zoo dua qub piv nrog cov thawj. Cov cuab yeej hluav taws xob siv hauv cov chaw tsim hluav taws xob, cov chaw tsim hluav taws xob, thiab cov khoom siv hluav taws xob ntawm lub vaj huam sib luag tswj feem ntau yog 0.5 lossis 0.2; Rau cov khoom siv, kev tiv thaiv kab relay feem ntau tsis tsawg dua 1 qib; Thaum siv rau kev ntsuas hluav taws xob, nyob ntawm qhov ntsuas qhov muaj peev xwm lossis kev siv hluav taws xob raws li cov cai ntawm cov kev cai xaiv (saib thawj cov lus qhuab qhia).

Qhov sib txawv ntawm qhov sib txawv: qhov yuam kev ntawm lub transformer muaj ob feem: qhov sib txawv ntawm qhov sib txawv thiab lub kaum sab xis sib txawv. Qhov kev ua yuam kev piv txwv, hu ua qhov sib txawv ntawm qhov sib txawv, feem ntau qhia los ntawm lub cim f, uas yog sib npaug ntawm qhov sib txawv ntawm qhov tseeb thib ob tam sim no thiab cov thawj tam sim no hloov mus rau theem nrab, thiab qhov piv ntawm thawj tam sim no hloov mus rau qhov Secondary sab, qhia raws li ib feem pua.

Lub kaum sab xis sib txawv: lub kaum sab xis qhov yuam kev yog hu ua lub kaum sib txawv, feem ntau qhia los ntawm lub cim δ, uas yog theem sib txawv ntawm cov vector thib ob thiab thawj vector tam sim no tom qab kev sib hloov 180 degree. Nws tau teev tseg tias qhov thib ob tam sim no vector ua ntej ntawm thawj qhov tam sim no vector δ yog qhov zoo, qhov rov qab yog qhov tsis zoo, thiab feeb (') yog siv los ua chav ntsuas.

Thermal stability thiab dynamic stability muaj ntau yam: Thaum lub hwj chim system tsis ua hauj lwm, tam sim no transformer yuav raug thermal nyhuv thiab electrodynamic nyhuv ntawm cov loj loj tam sim no tshwm sim los ntawm lub luv luv-circuit tam sim no, thiab tam sim no transformer yuav tsum muaj peev xwm tiv tsis tau puas. . Qhov no muaj peev xwm yog qhia los ntawm thermal stability thiab dynamic stability ntau. Qhov sib piv thermal stability yog qhov sib piv ntawm cov tam sim no uas tsis ua rau lub tshav kub ntawm lub tam sim no transformer kom tshaj qhov tso cai txwv tsis pub dhau 1s ntawm lub thermal stability tam sim no thiab cov ntsuas tam sim no ntawm transformer tam sim no. dynamic stability yam yog qhov piv ntawm qhov siab tshaj tam sim no tam sim no uas tam sim no transformer tuaj yeem tiv taus rau nws cov ntsuas tam sim no.
