Dry Type Transformer Temperature Setting & Operation Guide

Txheej txheem cej luam

Windings ntawm qhuav- hom transformers ua kom sov thaum ua haujlwm. Qhov kub thiab txias (txhais tau tias qhov sib txawv ntawm qhov hloov pauv qhov kub thiab txias, ntsuas hauv Kelvin) ncaj qha txiav txim siab lub neej ntawm rwb thaiv tsev thiab kev nyab xeeb ntawm kev ua haujlwm. Raws li lub teb chaws tus qauv GB / T 1094.11, qhov tsim nyog ntsuas kub thiab nruj tswj qhov kub thiab txias yog qhov tseem ceeb los xyuas kom meej lub sij hawm ntev -, txhim khu kev qha lag luam ntawm cov cuab yeej xws li 1000 kva qhuav hom transformers thiabqhuav hom kauj ruam down transformers. JINSHANMEN TECHNOLOGY CO., LTD tshwj xeeb hauv R&D thiab kev tsim cov roj-immersed fais fab transformers, qhuav-hom fais fab transformers, mining explosion-proof transformers, thiab amorphous alloy fais fab kis thiab xa khoom, xa cov khoom siv tau zoo, lub zog- txuag cov neeg siv khoom thoob ntiaj teb.

I. Temperature Rise Limits (los ntawm Chav Kawm Rwb Thaiv Tsev)        

Qhov ntsuas kub nce siab yog txiav txim siab los ntawm cov rwb thaiv tsev cov cua sov hauv chav kawm (raws li tus qauv ambient yam tsawg dua lossis sib npaug li 40 degree):

- Chav Kawm F Rwb thaiv tsev: Cov kev xaiv siv dav tshaj plaws, suav txog ntau dua 90% ntawm kev ua lag luam, tsim nyog rau feem ntau cov ntawv thov sab hauv; 1000 kva qhuav hom transformers feem ntau siv Class F rwb thaiv tsev.

- Chav H rwb thaiv tsev: Tsim los rau qhov hnyav ib puag ncig xws li siab - qhov chaw ua haujlwm kub thiab qhov cua tsis zoo hauv cov chav faib hluav taws xob hauv av; qhuav hom kauj ruam down transformers tuaj yeem nruab nrog Class H rwb thaiv tsev rau siab - kub ua haujlwm.

- Core Temperature Rise: Tsawg dua lossis sib npaug li 60K rau Class F rwb thaiv tsev thiab Tsawg dua lossis sib npaug rau 80K rau Class H rwb thaiv tsev.

II. Standard Temperature Controller Settings

Thaum configuring kub controllers rau 1000 kva qhuav hom transformers thiab qhuav hom kauj ruam down transformers, qhov pom zoo qhov ntsuas kub yog raws li nram no:

- Chav F (Qhov kub siab tshaj plaws: 155 degree)

Ceeb Toom Thaum Ntxov: 120℃(raws li qhov kub thiab txias ntawm 80K)

Ntxuam ua kom muaj zog: 130℃(alarm triggered)

Kev tiv thaiv kev mus ncig: 150 degree

- Chav H (Qhov kub siab tshaj plaws: 180 degree)

Ceeb Toom Thaum Ntxov: 140℃(raws li qhov kub thiab txias ntawm 100K)

Ntxuam ua kom muaj zog: 150℃(alarm triggered)

Kev tiv thaiv kev mus ncig: 170 degree

III. Peb qhov kev pheej hmoo ntawm kev kub ntxhov siab

1. Kev txo qis hauv rwb thaiv tsev lub neej (rau-Txoj Cai Kawm Qib Siab): Rau txhua txhua 6℃nce hauv kev khiav hauj lwm kub, lub rwb thaiv tsev lub neej yog halved. Ntev -lub sij hawm overheating tuaj yeem txo qhov kev ua haujlwm ntawm 20 xyoo mus rau tsawg dua 10 xyoo.

2. Txo Load-Ntev Peev Xwm: Thaum ambient kub tshaj 40 degree, lub transformer yuav tsum ua hauj lwm ntawm ib tug derated muaj peev xwm tiv thaiv tripping. Kev saib xyuas tshwj xeeb yuav tsum tau them rau cov khoom thauj khoom ntawm hom qhuav kauj ruam down transformers.

3. Kev siv hluav taws xob ntau ntxiv: Winding kuj nce li ntawm 4% rau txhua txhua 10℃qhov kub thiab txias, ua rau ntau dua tooj liab poob thiab nce mus ntev - nqi hluav taws xob.

IV. Common Uas Tshaj - Kub

Overloading: Thaum lub load tshaj tawm tshaj 100%, lub transformer qhov kub thiab txias nce los ntawm 6-8℃rau txhua 10% nce nyob rau hauv load. Lub load factor ntawm1000 kva qhuav hom transformersyuav tsum tau saib xyuas thiab tswj kom nruj.

Cov cua kub tsis zoo: Cov teeb meem tshwm sim muaj xws li kiv cua ua haujlwm tsis zoo, plua plav thaiv, qhov cua tsis txaus, lossis qhov kub ntawm qhov kub siab tshaj 40 degree.

Peb-Phase Imbalance: Qhov sib txawv tam sim no tshaj 10% ntawm theem tuaj yeem ua rau muaj cua sov hauv zos.

Loose Wiring: Oxidized los yog xoob terminals nce kev tiv thaiv, ua rau lub zos overheating uas hloov mus rau windings.

V. Kev ntsuas kub thiab kev saib xyuas zoo tshaj plaws

1. Hierarchical Early Warning (Intelligent Temperature Controller)

Theem 1 (80% ntawm qhov ntsuas kub nce siab): Saib xyuas qhov hloov pauv ntawm cov khoom thauj

Theem 2 (90% ntawm qhov ntsuas kub nce): Ua kom cua txias txias

Theem 3 (Tsuas Kub Rise Limited): Ua kom muaj kev tiv thaiv kev mus los los tiv thaiv cov khoom puas

2. Kev tshuaj xyuas txhua hnub

Txhua Hnub: Txheeb xyuas peb -theem tam sim no tshuav nyiaj li cas (kev sib txawv yuav tsum yog <10%)

Txhua lub limtiam: Tshuab cov plua plav tawm ntawm cov cua uas siv cov cua huv huv (tsis txhob ntxuav dej kom nruj)

Txhua hli: Tshawb xyuas cov kiv cua ua haujlwm thiab xyuas qhov tseeb ntawm qhov ntsuas kub

3. Kev kuaj tsis tu ncua

Txhua Rau Rau Lub Hlis: Ntsuas cov rwb thaiv tsev tiv thaiv siv 2500V megohmmeter (kev nyeem ntawv ntau dua lossis sib npaug rau 1000MΩ ntawm 20℃yog suav tias tsim nyog)

Ib xyoos ib zaug: Ua kev ntsuas kev tiv thaiv kev tiv thaiv thiab ntsuas kub nce siab (ua raws li kev ntsuas ntsuas rau 4-8 teev)

VI. Xaus

Temperature Setting Core: Class F transformers - tswb ntawm 130℃/ mus ncig ntawm 150 degree; Class H transformers - tswb ntawm 150℃/ mus ncig ntawm 170 degree.

Ob qho tib si 1000 kva qhuav hom transformers thiab qhuav hom kauj ruam down transformers yuav tsum ua raws li GB / T 1094.11, nrog kub nce nruj tswj nyob rau hauv cov kev txwv.

Kev ua haujlwm txhua hnub thiab kev saib xyuas yuav tsum tsom mus rau hierarchical kub tswj kev ceeb toom ntxov, kev tu plua plav tsis tu ncua, thiab peb - kev saib xyuas cov theem - cov kev coj ua no txhawb nqa lub neej ntawm cov cuab yeej thiab txo qis kev siv hluav taws xob.
