300 KVA Tuag Pem Hauv Ntej Transformers-12.47/0.208 KV|Canada 2024

01 General

1.1 Project Description

Xyoo 2024, ib tus neeg siv khoom Canadian tau tso cai rau yim 300 KVA tuag pem hauv ntej transformers tsim thiab tsim ua raws li CSA Standard C227.4: 21. Cov transformers no yog tsim los txhim khu kev qha nyob rau hauv sab nraum zoov, voj-fed tis systems nrog zoo hauv av networks.

A 300 kVA peb-theem ncoo-mounted transformer tau muab los ua ib feem ntawm qhov project no. Nws muaj qhov tuag- tsim qauv pem hauv ntej uas ua kom muaj kev nyab xeeb thiab ua haujlwm yooj yim. Txoj kev ua kom txias yog ONAN, muab cov cua sov kom ntseeg tau raws li txhua qhov kev thauj khoom. Lub transformer siv cov ntxhia roj rwb thaiv tsev thiab aluminium windings, muab qhov sib npaug zoo ntawm kev ua haujlwm siab thiab tus nqi. Nws tau ntsuas ntawm 300 kVA, 60 Hz, nrog thawj qhov hluav taws xob ntawm 12.47 / 4.16 kV thiab theem nrab voltage ntawm 0.208 kV.

Qhov kev sib txuas winding yog YNyn0, haum rau kev sib txuas hauv av. Tsis muaj -load kais hloov pauv (NLTC) yog muab nrog ± 2 × 2.5% tapping ntau yam. Qhov no tso cai rau kev hloov kho qhov hluav taws xob yooj yim kom phim cov kev ua haujlwm sib txawv thiab ua kom ruaj khov kev ua haujlwm. Lub transformer ua tiav 98.94% kev ua haujlwm zoo, tsis muaj-load poob Tsawg dua lossis sib npaug li 800 W thiab qhov poob qis dua lossis sib npaug li 3580 W. Nws nta CSA tus qauv- ua raws cov khoom siv thiab 5-legged core tsim rau kev ua haujlwm ruaj khov nyob rau hauv kev sib txuas hauv av Y-Y.

Qhov kev xa khoom no qhia txogSCOTECH txoj kev mob siab rau kev xa khoom siab - zoo, CSA- tau ntawv pov thawj transformers tailored rau Canadian fais fab kev lag luam.

02 Kev tsim khoom

2.1 Oil Level Indicator

Cov roj ntsuas ntsuas cia koj pom 300 KVA tuag pem hauv ntej transformers 'cov roj ntawm ib nrais muag, nyob rau lub sijhawm tiag tiag, yog li koj paub tias nws yog qhov twg nws yuav tsum nyob. Roj tsis yog rwb thaiv tsev xwb- nws tshem tawm cua sov los ntawm windings thiab cov tub ntxhais ib yam nkaus. Yog tias qib poob qis, nws tuaj yeem yog qhov xau, lossis ib yam dab tsi hauv yuav tsis raug. Nrog kev pom cues lossis sensors, cov neeg ua haujlwm tuaj yeem sau lossis tshawb xyuas sai, pab tiv thaiv kev ua tsis tiav thiab txuas lub neej ntev. Feem ntau ntsia qhov twg nws yooj yim los xyuas, nws ua rau kev soj ntsuam txhua hnub kom nyab xeeb thiab yooj yim dua.

2.2 IFD & Drain Valve

Lub Internal Fault Detector, IFD, thiab lub qhov dej ntws tawm txhua tus muaj lawv lub luag haujlwm, tab sis ua ke lawv ua kom lub transformer muaj kev nyab xeeb. IFD hnov ​​​​cov pa txawv txawv lossis cov teeb liab arc me me, ceeb toom txog cov teeb meem cua ntsawj ntshab lossis teeb meem thaum ntxov. Lub valve tso cai rau koj tshem tawm cov roj, rau kev saib xyuas tsis tu ncua lossis xwm txheej ceev. Nrog rau ob qho tib si, koj tuaj yeem ntes cov kev pheej hmoo thaum ntxov thiab tswj cov roj yam xyuam xim. Tshwj xeeb tshaj yog nyob rau hauv peb -theem transformers, ceeb toom raws sij hawm thiab tswj cov roj tuav pab ua kom txhua yam ruaj khov thiab tsis txhob muaj teeb meem loj dua hauv kab.

2.3 Siab Relief Valve & Nqus Ntsuas Ntsuas

Nyob rau hauv lub transformer, lub siab nyem valve thiab lub tshuab nqus tsev ntsuas ntsuas ua raws li ib tug me ntsis kev nyab xeeb pab neeg. Lub valve nyem- qhib thaum cov roj siab nce siab dhau; tiv thaiv tank, seals. Lub tshuab nqus tsev vacuum- qhia txog kev hloov pauv siab, qhia txog qhov kub thiab txias, nthuav dav roj, tej zaum yuav muaj teeb meem kev sib khi. Ua ke, saib nrawm muab cov neeg ua haujlwm saib tag nrho. Pom overpressure, tsis zoo siab ntxov; pab txuag rwb thaiv tsev, mechanical qhov chaw. Tshwj xeeb tshaj yog tseem ceeb nyob rau hauv peb -theem transformers, qhov twg ib qho txhaum yuav ripple los ntawm tag nrho cov chav tsev.

 

2.4 Thermometer

Tus pas ntsuas kub ntsuas cov roj thiab cov cua kub cua, qhia tias qhov kub ntawm lub transformer khiav li cas. High tshav kub hnub nyoog roj sai dua, stresses rwb thaiv tsev, thiab muaj peev xwm overwork windings. Kev saib cov ntawv nyeem pab cov neeg ua haujlwm txiav txim siab seb puas yuav txo qis, tso cua ntau dua, lossis npaj kho. Cov ntaub ntawv tuaj yeem tshawb xyuas manually lossis pub rau hauv kev saib xyuas. Rau peb -theem theem, nws yog ib qho tseem ceeb kom pom txhua theem ntawm qhov kub thiab txias, ua kom cov khoom sib npaug, tsis txhob xav tsis thoob, thiab ua kom lub zog ntws mus tsis tu ncua.
