1. Qhib lub thawv rau kev tshuaj xyuas ua ntej kev teeb tsa

Xyuas seb lub ntim puas zoo. Tom qab lub transformer yog unpacked, xyuas seb cov ntaub ntawv ntawm lub nameplate ntawm transformer raws li tus tsim yuav tsum tau, seb lub Hoobkas cov ntaub ntawv ua tiav, seb lub transformer puas nyob rau hauv zoo, seb puas muaj tej yam kos npe rau ntawm kev puas tsuaj rau sab nraud, seb cov khoom puas lawm. thiab puas, seb puas yog cov khoom siv hluav taws xob los yog cov khoom sib txuas yog tias muaj kev puas tsuaj, thaum kawg xyuas seb puas muaj kev puas tsuaj thiab tsis txaus ntawm cov khoom seem.

2. Transformer installation

Ua ntej kos lub hauv paus ntawm lub transformer los xyuas seb lub pre-embedded steel phaj yog qib. Yuav tsum tsis muaj qhov tshwm sim cavitation nyob rau hauv lub phaj steel los xyuas kom meej tias lub hauv paus ntawm lub transformer muaj kev poob siab zoo thiab kev ua haujlwm ntawm lub suab, txwv tsis pub lub suab nrov ntawm lub transformer tom qab kev teeb tsa yuav nce. Tom qab ntawd, siv cov menyuam txav lub tshuab hloov mus rau qhov chaw teeb tsa, tshem tawm cov menyuam, thiab kho qhov hloov pauv kom raug rau txoj haujlwm tsim, thiab kev teeb tsa theem yuam kev ua tau raws li cov qauv tsim. Thaum kawg, plaub lub voj voog luv luv yog welded rau ntawm plaub lub ces kaum ze rau ntawm lub hauv paus transformer, uas yog, nyob rau hauv pre-embedded steel phaj, thiaj li hais tias txoj hauj lwm ntawm lub transformer tsis txav thaum siv.

3. Transformer xaim

Thaum xaim, qhov kev ncua deb tsawg kawg nkaus ntawm lub cev hluav taws xob thiab lub cev hluav taws xob mus rau hauv av yuav tsum tau ua kom ntseeg tau, tshwj xeeb tshaj yog qhov kev ncua deb ntawm lub cable mus rau high-voltage coil. Lub high-tam sim no low-voltage busbar yuav tsum tau txais kev txhawb nqa nyias, thiab yuav tsum tsis txhob txuas ncaj qha mus rau lub davhlau ya nyob twg transformer kom ua rau cov neeg kho tshuab ntau dhau thiab torque. Thaum qhov tam sim no ntau dua 1000A (xws li 2000A low-voltage busbar siv nyob rau hauv qhov project no), lub busbar thiab transformer yuav tsum muaj kev sib txuas muag ntawm cov terminals los them rau qhov thermal expansion thiab contraction ntawm tus neeg xyuas pib thiab cais cov kev vibration ntawm busbar thiab transformer. Kev sib txuas hluav taws xob ntawm txhua qhov xaim yuav tsum tswj xyuas qhov kev sib cuag uas tsim nyog. Elastic cov ntsiab lus (xws li disc-shaped yas rings los yog caij nplooj ntoos hlav washers) yuav tsum tau siv. Thaum zawm cov bolts txuas, yuav tsum siv lub torque wrench. Lub torque siv tus nqi muab los ntawm cov chaw tsim khoom yog qhia hauv Table 1 qhia

4. Transformer grounding

Lub hauv paus ntsiab lus ntawm lub transformer yog nyob rau hauv lub hauv paus ntawm lub low-voltage sab, thiab coj mus rau ib tug tshwj xeeb grounding bolt, uas yog cim nrog ib tug grounding cim. Lub grounding ntawm lub transformer yuav tsum muaj kev ntseeg siab txuas nrog kev tiv thaiv grounding system los ntawm qhov no. Thaum lub transformer muaj ib tug casing, lub casing yuav tsum tau kev cob cog rua rau lub hauv paus system. Thaum sab qis-voltage txais yuav peb-theem plaub-xaim system, cov xaim nruab nrab yuav tsum muaj kev ntseeg siab txuas rau hauv av.

5. Kev tshuaj xyuas ua ntej transformer ua haujlwm

Xyuas seb tag nrho cov fasteners puas xoob, seb qhov kev sib txuas hluav taws xob puas yog thiab txhim khu kev qha, seb qhov rwb thaiv tsev qhov deb ntawm lub cev raug them thiab lub cev them rau hauv av ua tau raws li cov kev cai, yuav tsum tsis muaj qhov txawv txav ze ntawm lub transformer, thiab cov coil nto yuav tsum muaj. huv si.

6. Debugging ua ntej transformer ua haujlwm

(1) Tshawb xyuas qhov kev hloov pauv thiab kev sib txuas ntawm pawg transformer, ntsuas qhov DC tsis kam ntawm qhov siab thiab tsis tshua muaj hluav taws xob windings, thiab sib piv cov txiaj ntsig nrog lub Hoobkas kuaj cov ntaub ntawv muab los ntawm cov chaw tsim khoom.

(2) Tshawb xyuas cov rwb thaiv tsev tiv thaiv ntawm cov coils thiab coil rau hauv av. Yog hais tias lub rwb thaiv tsev tsis kam yog qis dua cov ntaub ntawv ntsuas ntawm lub Hoobkas, nws qhia tau hais tias lub transformer yog damp. Thaum lub rwb thaiv tsev tiv thaiv qis dua 1000Ω / V (kev ua haujlwm voltage), lub tshuab hloov pauv yuav tsum qhuav.

(3) Kev ntsuas qhov ntsuas hluav taws xob ntawm qhov ntsuas hluav taws xob tiv thaiv yuav tsum ua raws li cov cai. Thaum ua qhov tsis tshua muaj hluav taws xob tiv thaiv qhov ntsuas hluav taws xob, qhov ntsuas kub ntsuas TP100 yuav tsum tau muab tshem tawm, thiab lub ntsuas hluav taws xob yuav tsum tau xa rov qab mus rau nws qhov chaw nyob rau lub sijhawm tom qab qhov kev xeem dhau lawm.

(4) Thaum lub tshuab hloov pauv tau nruab nrog lub kiv cua, lub kiv cua yuav tsum muaj zog thiab ua haujlwm kom ntseeg tau tias nws ua haujlwm li qub.

7. Kev sim khiav

Tom qab lub transformer tau ua tib zoo tshuaj xyuas ua ntej muab tso rau hauv kev ua haujlwm, nws tuaj yeem ua kom muaj zog rau kev sim ua haujlwm. Thaum lub caij xeem khiav, yuav tsum tau them nyiaj tshwj xeeb los xyuas cov ntsiab lus hauv qab no. Tshawb xyuas cov suab txawv txav, suab nrov thiab kev vibrations. Puas muaj qhov txawv txav xws li tsw ntxhiab tsw? Seb puas muaj kev hloov xim los ntawm lub zos overheating. Seb qhov cua yog qhov zoo. Ntxiv rau, cov ntsiab lus hauv qab no yuav tsum tau sau tseg.

Ua ntej, txawm hais tias lub tshuab ziab khaub ncaws qhuav muaj qhov muaj zog noo noo tsis kam, nws tseem ua rau ya raws vim nws feem ntau yog cov qauv qhib, tshwj xeeb tshaj yog cov tshuab ziab khaub ncaws uas ua rau hauv kuv lub teb chaws muaj qhov rwb thaiv tsev qis (qhib rwb thaiv tsev). Yog li ntawd, cov tshuab ziab khaub ncaws qhuav tuaj yeem tsuas yog tau txais kev ntseeg siab thaum tus txheeb ze av noo qis dua 70%. Cov tshuab ziab khaub ncaws qhuav yuav tsum zam kom tsis txhob tawg mus ntev kom tsis txhob ntub dej hnyav. Thaum cov nqi hluav taws xob tiv thaiv qis dua 1000 / V (kev ua haujlwm voltage), nws txhais tau hais tias lub transformer yog dej ntub, thiab qhov kev xeem khiav yuav tsum tau nres.

Qhov thib ob, lub tshuab ziab khaub ncaws qhuav siv rau kev nce qib hauv qhov chaw nres tsheb fais fab yog txawv ntawm cov roj-immersed transformer. Kev ua haujlwm qhib-circuit nyob rau sab qis-voltage yog txwv, kom tsis txhob muaj kev puas tsuaj ntawm cov khoom siv hluav taws xob qhuav vim yog overvoltage ntawm daim phiaj sab lossis xob laim ntawm txoj kab, ua rau muaj kev sib kis ntau dhau. Txhawm rau tiv thaiv kev phom sij ntawm kev sib kis overvoltage, cov txheej txheem tiv thaiv kev tiv thaiv overvoltage surge arresters (xws li Y5CS zinc oxide ntes) yuav tsum tau muab ntsia rau ntawm qhov hluav taws xob tsheb npav ntawm lub tshuab ziab khaub ncaws.
