COV KEV CEEB TOOM RAU KEV SIV COV ROJ-IMMERSED TEST TRANSFORMERS

Cov kev ceev faj rau kev siv cov roj-immersed kuaj transformers yog raws li nram no:

1. Txuas lub voj voog ua haujlwm raws li qhov kev sim uas xav tau. Lub plhaub ntawm lub tshuab hloov pauv roj thiab lub plhaub ntawm lub thawv tswj (rooj) yuav tsum tau grounded kom ntseeg tau. X-kawg (tus Tsov tus tw siab voltage) ntawm lub winding siab ntawm lub tshuab hloov pauv roj thiab F-kawg ntawm lub winding ntsuas yuav tsum tau grounded kom ntseeg tau.

2. Thaum ua qhov kev sim cascade, lub davhlau ya nyob twg X ntawm qhov thib ob thiab thib peb qis-voltage windings, lub davhlau ya nyob twg F ntawm qhov ntsuas winding thiab lub davhlau ya nyob twg X (high-voltage tw) ntawm qhov siab-voltage winding yog txuas nrog lub casing ntawm qhov kev sim transformer ntawm theem no. Lub casing sab nraud ntawm qhov thib ob- thiab thib peb-theem roj-immersed kev sim transformers yuav tsum tau grounded los ntawm kev txhawb nqa insulating.

3. Ua ntej qhib lub hwj chim, lub zog tswj hwm ntawm lub thawv tswj hwm roj-immersed kuaj transformer (chav tsev) yuav tsum tau kho kom xoom ua ntej qhib lub hwj chim, kaw lub qhov hloov, thiab pib txhawb lub zog.

4. Tig lub log tes ntawm lub regulator kom sib npaug zos kom nce lub siab los ntawm xoom. Cov txheej txheem txhawb nqa yog: txoj kev txhawb nqa sai, uas yog 20s kauj ruam-rau-kauj ruam txhawb nqa; txoj kev txhawb nqa qeeb, uas yog 60s kauj ruam-rau-kauj ruam txhawb nqa; txoj kev txhawb nqa qeeb heev rau kev xaiv.

Tom qab lub zog hluav taws xob nce ntawm xoom mus rau 75% ntawm qhov ntsuas hluav taws xob uas koj xav tau hauv qee txoj kev txhawb nqa thiab qhov ceev, nws nce mus rau qhov ntsuas hluav taws xob uas koj xav tau ntawm qhov ceev ntawm 2% ntawm qhov ntsuas hluav taws xob ib ob, thiab ua tib zoo mloog qhov ntsuas ntawm lub 'meter' thiab qhov xwm txheej ntawm cov khoom sim. Yog tias qhov qhia ntawm lub cuab yeej ntsuas thiab qhov xwm txheej ntawm cov khoom sim pom tias tsis zoo thaum lub sijhawm nce qib ntawm lub tshuab hloov pauv roj lossis thaum lub sijhawm sim, lub siab yuav tsum txo qis tam sim ntawd, lub zog fais fab yuav tsum raug txiav tawm, thiab qhov xwm txheej yuav tsum tau kuaj xyuas.

5. Tom qab qhov kev sim, lub zog tswj hluav taws xob yuav tsum rov qab mus rau qhov chaw xoom ntawm qhov ceev tas li hauv ob peb feeb, thiab tom qab ntawd lub zog fais fab yuav tsum raug txiav tawm.

6. Tsis txhob siv ntau tshaj qhov ntsuas uas tau teev tseg. Tsuas yog thaum tsim nyog rau kev sim xwb, tsis txhob cia muaj zog tag nrho lossis tsis muaj zog.

7. Thaum ua qhov kev sim siab siab, ntxiv rau kev paub txog phau ntawv qhia khoom, nws tseem yog qhov tsim nyog los ua raws li cov qauv hauv tebchaws thiab cov txheej txheem ua haujlwm. Saib GB311-83 "Kev sib koom tes rwb thaiv tsev ntawm cov khoom siv hluav taws xob siab thiab kev hloov pauv, kev siv tshuab ntsuas hluav taws xob siab"; "Cov txheej txheem sim tiv thaiv cov khoom siv hluav taws xob" thiab lwm yam.
