Instrument Tam sim no Transformer

Raws li peb txhua tus paub, rau kev nyab xeeb, nruab nrab thiab siab voltage tam sim no transformers nyob rau hauv transformer xeem chaw nres tsheb feem ntau yog muab tso rau hauv lub platform ntawm nruab nrab transformer thiab cov transformer kuaj. Vim tias qhov siab ntawm lub platform yog nyob nruab nrab ntawm 2-4m, nws tsis yooj yim heev rau manually hloov qhov kev sib txuas ntau mus nce thiab nqis ntawm lub platform.

Nyob rau hauv xyoo tas los no, muaj ntau txoj hauv kev los daws qhov teeb meem no hauv kev lag luam hauv tsev, uas tsis txaus siab

(1) Tam sim no transformer muab faib ua 2-3 ntu ntawm thawj zaug thiab 3-4 ntu ntawm lub sijhawm thib ob. Qhov thib ob tuaj yeem hloov tau los ntawm kais hloov pauv. Nws txo tus naj npawb ntawm kev hloov ib zaug, tab sis tom qab tag nrho, nws yuav tsum tau hloov cov kab ntawm thiab tawm ntawm lub platform ib zaug, uas ua rau muaj qhov tsis zoo rau cov neeg ua haujlwm xeem.

(2) Nws tuaj yeem siv ua hluav taws xob thawj qhov hluav taws xob siab hloov pauv hloov pauv. Hloov thiab tam sim no transformer yog ywj siab ntawm ib leeg thiab txuas nrog tooj liab bar. High voltage hloov tau tus nqi siab, siab tsis ua hauj lwm tus nqi thiab tsis muaj kev cia siab rau. Qhov kev tso tawm ib nrab yog siab dua 50pc. Tsis muaj kev tso tawm ib nrab.

(3) Qee lub tuam txhab tau tsim cov khoom siv sib xyaw ua ke ntawm tam sim no transformer thiab kais hloov pauv. Nws zoo nkaus li compact, tab sis feem ntau ntawm lawv raug puas vim hloov tsis ua hauj lwm thaum lub sij hawm warranty, uas ua rau ntau lawm nres.

Nyob rau hauv xyoo tas los no, peb lub tuam txhab tau tsim ib hom tshiab ntawm tam sim no transformer raws li cov kev cai ntawm cov neeg siv txawv teb chaws

(1) Ua tiav hauv qhov kev hloov pauv theem nrab, ntawm kev hloov pauv hloov, hauv kev hloov hluav taws xob theem nrab, nws yooj yim heev rau siv, thiab txuag lub hauv paus hloov nrog qhov tsis ua haujlwm siab.

(2) Compatibility nrog lub hwj chim analyzer: theem nrab ntsuas tam sim no yog 1a, tsis yog 5A. Siv lub zog ntsuas hluav taws xob, qhov ntsuas thib ob tuaj yeem yog 1a. Siv W-3000 lub zog ntsuas hluav taws xob ua piv txwv, daim ntawv no piav qhia txog kev hloov pauv ntawm qhov hloov pauv tam sim no thiab lub zog ntsuas hluav taws xob: cov channel tam sim no ntawm W-3000 lub zog ntsuas hluav taws xob muaj ob qhov loj thiab me me, thiab cov channel me me tam sim no raug xaiv. Qhov ntsuas tam sim no yog 5mA, 10mA, 20mA, 50mA, 100mA, 200mA, 500mA, 1A thiab 2a, nrog rau 9 lub zog hauv tag nrho, uas tuaj yeem hloov pauv nrog cov tswv yim tam sim no. Nws tuaj yeem hloov kho rau tam sim no transformer ntawm theem nrab 1a.

Lub input impedance ntawm me me tam sim no channel ntawm W-3000 lub hwj chim analyzer yog 0.5 Ω, thiab lub thib ob Circuit Court impedance yog 0.3 Ω feem ntau, yog li qhov ntsuas tso zis yuav tsum yog 0.6-0.8va.

(3) Vim muaj kev txwv, qhov ntsuas tam sim no: IMAX / Imin ≤ 400, saib Table 1 thiab rooj 2 kom paub meej.

(4) Kev ua yuam kev: nrog qhov nce ntawm qhov tam sim no, qhov tseeb qib nce ntawm 0.2 txog 0.01. Cov yam ntxwv no tsuas yog tsim nyog rau kev sim transformer. Raws li peb txhua tus paub, vim hais tias lub hwj chim ntawm qhov tsis muaj kev ntsuas yog nyob rau hauv qhov kev txiav txim ntawm 0.2, high-precision transformer tsis xav tau. Lub sijhawm no, qhov qis qis ntawm 50A thiab qis dua yog siv, thiab qhov tseeb txaus. Lub zog ntawm qhov ntsuas qhov ntsuas yog qhov tsawg heev (txog 0.02-0.01), uas yuav tsum muaj qhov tseeb ntawm qhov hloov pauv. Lub sijhawm no, qhov siab ntawm ntu ntawm 100A thiab siab dua yog siv, thiab qhov tseeb yog qhov siab heev, mus txog 0.01 qib.

Thaum IMAX / Imin ≤ 400, qhov tseeb theem ntawm ntau qhov sib piv tam sim no tau qhia hauv Table 1 thiab rooj 2

Peb paub tias cov qauv ntawm transformer poob kev ntsuas qhov yuam kev: Δ P% = 0.0291 δ TG φ% (1) Qhov twg δ yog qhov sib txawv (unit: feeb) φ ntawm lub kaum sab xis sib txawv ntawm tam sim no transformer thiab voltage transformer yog lub hwj chim yam lub kaum sab xis thaum lub sij hawm kev xeem. Qhov ntau ntawm cov tam sim no me me yog 5 / 1a-50 / 1a, uas yog siv rau kev kuaj tsis muaj load. Cos φ yog hais txog 0.2 thaum tsis muaj-load test, uas yog, TG φ yog 1.9. Qhov siab tshaj plaws angular sib txawv ntawm qib qis tshaj 0.2 yog ± 10. Qhov sib txuam voltage transformer siv tau raws li qib 0.01, qhov siab tshaj plaws lub kaum sab xis sib txawv yog ± 0.3, thiab qhov siab tshaj qhov sib txawv δ ntawm lawv yog ± 10.3. Tus nqi yog hloov mus rau hauv cov mis (1) Δ P% = 0.0291 × (± 10.3,) × 1.9% = ± 0.57%, uas yog qhov yuam kev siab tshaj plaws ntawm chav kawm 0.2. Yog tias siv 0.1 iav, qhov yuam kev tseem yog ib nrab, uas yuav tsum tau hais tias yog qhov tseeb heev. Qhov piv txwv tam sim no siv hauv kev ntsuas load yog siab dua 100/1a, thiab qhov tseeb yog 0.01. Piv txwv li, 35/10kv, 3150kva transformer, ntsuas tam sim no ntawm 35kV sab yog 52A, thiab 100/1a iav yuav tsum raug xaiv. 657e23 ib

Tus nqi ntawm cov khoom no yog tsawg tshaj li qhov sib npaug ntawm qhov tam sim no transformer thiab nws cov kais hloov pauv ntawm thawj qhov kev hloov pauv. Txhua qib voltage tuaj yeem siv tau. Cov thev naus laus zis no yog ua raws li kev hloov pauv hloov tshiab ntawm electromagnetic tam sim no transformer nws tus kheej, tsis yog siv hluav taws xob amplifier los hloov ntau yam hauv lub sijhawm thib ob, zoo li lub tuam txhab Swiss haefely trench. Cov qauv no yog thawj zaug hauv ntiaj teb, kev tsim khoom tshwj xeeb, thiab lwm tus yuav tsis. Piv nrog rau haefield, qhov zoo ntawm peb tam sim no transformer tshiab yog raws li nram no:

(1) Kev ua haujlwm siab heev. Kev ntsuas transformer kuj tseem tuaj yeem ua nyob rau hauv qhov chaw taws teeb thib ob hloov pauv, nrog rau tus nqi kwv yees li 1/10 ntawm Switzerland.

(2) Kev ntseeg siab. Tsis muaj hluav taws xob amplifier, kev ntseeg siab. Cov khoom siv hluav taws xob tau yooj yim puas tsuaj los ntawm qhov hluav taws xob hauv qhov chaw kuaj hluav taws xob siab. Yog tias nws puas lawm, nws tsuas yog xa mus rau Switzerland kho, uas tsis tuaj yeem kho hauv Suav teb. Cov neeg siv khoom siv hluav taws xob tshiab tam sim no tau qhia hauv cov lus hauv qab no:
