Distribution Transformer Loading Guide
Fais fab transformers yog ib qho tseem ceeb ntawm cov hluav taws xob faib hluav taws xob. Lawv yog lub luag haujlwm los txo qhov hluav taws xob los ntawm cov kab hluav taws xob hluav taws xob siab mus rau qhov qis qis uas yuav tsum tau muaj los ntawm cov tsev thiab cov lag luam. Transformers yog tsim los tswj cov nqi zog. Nws yog ib qho tseem ceeb uas yuav tau ua raws li qee cov lus qhia thaum thauj cov khoom xa tawm kom ntseeg tau tias lawv ua haujlwm tau zoo thiab nyab xeeb.
1. Muaj peev xwm thauj khoom siab tshaj plaws
Thawj kauj ruam hauv kev thauj khoom ntawm lub tshuab hluav taws xob faib khoom yog los txiav txim siab nws lub peev xwm siab tshaj plaws. Transformers raug ntsuas los ntawm lawv qhov ntsuas kVA (kilovolt-ampere). Qhov kev ntsuas no yog qhov siab tshaj plaws uas lub tshuab hloov pauv tuaj yeem ua haujlwm raws li kev ua haujlwm ib txwm muaj. Tshaj qhov ntsuas no tuaj yeem ua rau lub tshuab hluav taws xob overheat, uas tuaj yeem ua rau cov cuab yeej tsis ua haujlwm thiab txawm tias hluav taws kub.
2. Load Profile
Nws yog ib qho tseem ceeb kom nkag siab txog qhov load profile ntawm lub transformer thaum txiav txim siab yuav ua li cas thauj nws. Load profile yog hais txog tus nqi ntawm cov khoom thauj uas lub transformer yuav nqa ntawm lub sijhawm sib txawv ntawm hnub. Piv txwv li, lub transformer uas yog loaded hnyav thaum nruab hnub yuav muaj ib tug tsawg load thaum hmo ntuj. Kev nkag siab txog cov ntaub ntawv thauj khoom pab txiav txim siab seb lub tshuab hloov pauv puas yog qhov loj me rau cov khoom thauj nws yuav nqa.
3. Sib npaug Load
Transformers yog tsim los nqa cov loads uas sib npaug ntawm txhua theem. Cov loads tsis sib npaug tuaj yeem tsim kev ntxhov siab ntxiv, ua rau cov khoom siv tsis ua haujlwm. Txhawm rau kom ntseeg tau tias cov khoom sib npaug, nws yog ib qho tseem ceeb uas yuav tsum ntsuas qhov amperage ntawm txhua theem thiab kho raws li qhov tsim nyog.
4. Kub
Qhov ntsuas kub ntawm transformer ua haujlwm yog qhov tseem ceeb hauv kev txiav txim siab nws cov load. Qhov ntsuas kub siab tuaj yeem ua rau cov rwb thaiv tsev tsis ua haujlwm thiab txo cov kev pab cuam lub neej. Qhov kub ntawm lub transformer tuaj yeem ntsuas tau los ntawm kev siv cov ntsuas kub, xws li thermal imaging koob yees duab. Thaum lub sijhawm thauj khoom siab tshaj plaws, qhov ntsuas kub yuav tsum tau saib xyuas kom ntseeg tau tias nws tseem nyob hauv qhov kev txwv.
5. Kev tu
Kev saib xyuas kom zoo ntawm transformers yog qhov tseem ceeb hauv kev ua kom lawv ua haujlwm zoo thiab ua haujlwm zoo. Kev saib xyuas suav nrog kev tshuaj xyuas qhov muag, kuaj roj thiab tshuaj xyuas, thiab kuaj hluav taws xob. Kev saib xyuas tsis tu ncua tuaj yeem pab txheeb xyuas cov teeb meem muaj peev xwm thiab tiv thaiv kom tsis txhob muaj teeb meem loj dua.
Xaus
Kev thauj khoom ntawm lub tshuab hluav taws xob faib khoom yog ib txoj haujlwm tseem ceeb uas yuav tsum tau ua kom zoo. Ua raws li cov lus qhia no yuav pab xyuas kom lub transformer ua haujlwm zoo thiab nyab xeeb. Kev tswj xyuas kom zoo ntawm cov khoom siv hluav taws xob yog qhov tseem ceeb los tswj kev ncaj ncees ntawm cov hluav taws xob faib hluav taws xob thiab tiv thaiv cov khoom siv tsis ua haujlwm. Kev saib xyuas tsis tu ncua tuaj yeem pab txheeb xyuas cov teeb meem ntxov thiab tiv thaiv kev kho tus nqi.
