Khoom nta thiab Scope ntawm kev siv

JLSZV35 series peb-theem sab nraum zoov, qhuav-hom, dav-load ua ke transformer (nrog metering lub thawv), chav tsev Cheebtsam ntawm cov khoom yog insulated los ntawm sab nraum zoov epoxy resin casting, thiab chav tsev Cheebtsam yog sib sau ua ke rau hauv ib tug (los yog cais) qauv, yog li cov khoom muaj Nws muaj qhov zoo ntawm kev tiv thaiv ultraviolet, tiv thaiv kev laus, tiv thaiv nag thiab lwm yam.Cov khoom siv tuaj yeem siv rau ib qho, ob npaug thiab triple tam sim no piv, thiab qhov siab precision ntawm 0.2S ua kom qhov ntsuas qhov tseeb hauv qhov dav dav.Muab ob npaug rau thiab triple tam sim no piv tau txais tus qauv kais thib ob.
Peb-theem ob lub ntsiab lus fais fab ntsuas lub thawv (combination transformer)
Peb-theem peb-xaim ua ke transformer (ob lub ntsiab lus) muaj ob-theem voltage transformers (PT) thiab ob lub tam sim no transformers (CT).Ob lub PT thiab CT yog electromagnetic, thiab ob lub PT windings txuas nrog V / V.Ib qho kev ntsuas peb-theem yog tsim, thiab lub hauv paus windings ntawm ob lub CTs txuas nrog rau theem A thiab C ntawm kab sib txuas.Muaj ib lub hauv av ntsia hlau welded rau hauv qab mounting bracket.
Peb-theem peb-theem fais fab ntsuas lub thawv (combination transformer)
Peb-theem peb-theem hluav taws xob ntsuas lub thawv (combined transformer) Y / Y 0 kev sib txuas metering lub thawv yog cov khoom tsim tshiab tau txhim kho los ntawm peb-theem ob lub ntsiab lus VV kev sib txuas, vim tias nrog kev txhim kho txuas ntxiv ntawm lub neej niaj hnub no, lub zog. Daim phiaj xwm txheej thauj khoom kuj tseem txhim kho thiab hloov pauv tas li, piv txwv li: ib-theem kev kho ntawm cov hluav taws xob railways, hluav taws xob rauv smelting, rectification thiab electrolysis, thiab lwm yam, nrog rau kev sib haum xeeb hauv daim phiaj hluav taws xob, thiab qhov tsis sib xws ntawm theem loads tuaj yeem ua rau. tsis zoo ib yam los yog harmonics nyob rau hauv V / V kev twb kev txuas.Kev ntsuas tsis raug vim tias yoj tsis muaj channel (raws li qhov ntsuas qhov tseeb, Y / Y 0 txoj kev sib txuas tuaj yeem nce cov nyiaj tau los ntawm 3% -15%), yog li peb lub Hoobkas tau tsim tshiab Y / Y 0 txoj kev sib txuas ntawm lub thawv metering kom hloov mus rau qhov kev ua haujlwm nyuaj.Nws tuaj yeem ua kom muaj kev ntsuas qhov tseeb thiab koom tes nrog kev hloov kho tam sim no ntawm kev tswj hluav taws xob hluav taws xob.Lub thawv metering muaj cov yam ntxwv ntawm kev ntsuas hloov tau.Piv txwv li, ib-theem watt-teev meter tuaj yeem saib xyuas kev ua haujlwm ntawm txhua theem thauj khoom kom pom cov teeb meem hauv lub sijhawm.Yog hais tias lub load hloov tau zoo heev, thov siv S-chav kawm (kev ntsuas ntau ntawm 1%-120% ntawm qhov ntsuas tam sim no) tam sim no transformer siv nrog rau 1.5A-6A dav-load watt-teev meter, thiaj li zam qhov teeb meem ntawm kev hloov pauv tsis tu ncua..
Lub thawv ntsuas yog txuas nrog lub qhov hluav taws xob thib ob ntawm qhov sib xyaw ua ke transformer.Lub thawv ntsuas tau nruab nrog peb-theem nquag watt-teev meter thiab reactive watt-teev meter txhua, lossis peb-theem active thiab reactive sib xyaw ua ke lub zog ntsuas, uas tuaj yeem pom meej ntawm lub qhov rais saib lub thawv.Nyeem cov lej.
(1) JLSZV-35 series ua ke transformers tau sib sau ua ke los ntawm cov khoom qhuav qhuav, thiab tsis muaj teeb meem roj to, yog li tsis muaj roj yog pom tau;
(2) Qhov hluav taws xob thiab tam sim no yog tag nrho cov cam khwb cia nrog resin, zoo li lub tsev thaiv cov qauv, uas yog ib qho yooj yim los hloov, yooj yim los tswj, thiab txuag nqi;
(3) Cov khoom muaj siab precision, thiab tam sim no transformer tuaj yeem ncav cuag 0.2S qib, uas paub txog kev ntsuas dav dav;
(4) Kev siv cov ntaub ntawv ua rau cov khoom muaj siab dynamic thiab thermal stability;
(5) Qhov voltage tuaj yeem nruab nrog 220V auxiliary winding los muab lub zog rau cov keyboards, thiab lwm yam.

Kev teeb tsa thiab kev xaim

1. Lub thawv high-voltage metering yuav tsum tau muab tso rau kab rov tav, qhov siab ntawm lub installation ntawm tus ncej yuav tsum tsis txhob qis dua 300mm los ntawm hauv av, thiab lub watt-teev meter yuav tsum yog ntsug thiab tsis inclined ntawm yuav.
2. Cov khoom siv hluav taws xob kawg (thawj kab nkag sab) ntawm lub thawv high-voltage metering yuav tsum tau nruab nrog zinc oxide ntes ntawm cov theem voltage, thiab nws cov av tiv thaiv tsawg dua lossis sib npaug ntawm 10Ω los tiv thaiv ntau yam xob laim overvoltages, kev khiav hauj lwm overvoltages, thiab lub hwj chim zaus transient overvoltages, thiaj li tiv thaiv cov khoom siv hluav taws xob thiab cov khoom siv hluav taws xob hauv kab.
3. Rau kev xaim, ntu ntu A, B, C ntawm daim phiaj hluav taws xob yuav tsum raug txheeb xyuas nrog lub siab-voltage hluav taws xob lub zog ntsuas lub thawv, thiab theem ntu A, B, thiab C ntawm cov pas nrig conductive yuav tsum tau txuas nrog ( Cov theem ua ntu zus yuav tsum yog qhov zoo), P1 cov kab nkag, P2 tawm kab.
4. Muab ob npaug rau txoj kev sib txuas: hloov cov kab txuas txuas ntxiv: txuas S1-S2 rau qhov sib piv me me (S3 luv), txuas S1-S3 rau ntau qhov sib piv (S2 luv).
5. Thaum qhov sib piv yog ib qho, qhov thib ob S2 ntawm qhov tam sim no transformer thiab theem nrab b ntawm qhov voltage transformer txuas nrog hauv av.Thaum cov hloov pauv tam sim no hloov pauv ob npaug nrog qhov sib piv me me, S2 thiab qhov hluav taws xob hloov hluav taws xob b txuas nrog rau hauv av (S3 yog khoob), thaum siv qhov sib hloov loj, S3 txuas nrog rau hauv av ntawm qhov hluav taws xob transformer b. (S2 yog luv).
6. Thaum cov kab hluav taws xob high-voltage yog txhuas, nws yuav tsum tau txuas nrog tooj liab-aluminium hloov clips, tag nrho cov chassis yuav tsum tau grounded, tam sim no transformer yuav tsum tsis txhob qhib rau lub sij hawm thib ob, thiab voltage transformer yuav tsum tsis txhob luv. -circuited rau lub sijhawm thib ob.
7. Tom qab lub thawv ntsuas hluav taws xob high-voltage raug teeb tsa, sim thiab soj ntsuam nrog kev thauj khoom kom pom tias lub ntsuas hluav taws xob nquag thiab reactive zog tig ib txwm.
8. Tom qab cov kev xeem thiab kev soj ntsuam saum toj no, nws tuaj yeem raug muab tso rau hauv kev ua haujlwm tom qab dhau qhov kev xeem.
