Ua tau zoo thiab ruaj khov 300 kVA ncoo -mounted transformer rau kev txhim khu kev qha sab nraum zoov fais fab.
01 General
1.1 Project Description
Hauv 2024, ib tus neeg siv khoom Canadian tau txais a300 kVA peb-theem ncoo-mounted transformer, tsim thiab tsim nyob rau hauv tag nrho ua raws li CSA Standard C227.4:21. Chav tsev yog npaj rau sab nraum zoov ncoo-mounting ntawm lub hauv paus pob zeb thiab yog haum rau siv nyob rau hauv zoo grounded systems.
Qhov no transformer nta ib tug tuag- pem hauv ntej tsim rau kev nyab xeeb thiab kev cia siab nyob rau hauv sab nraum zoov installation. Nws siv ONAN txias thiab ntxhia roj rau rwb thaiv tsev. Aluminium windings muab qhov sib npaug zoo ntawm kev ua haujlwm, qhov hnyav, thiab tus nqi. Lub transformer yog ntsuas 300 kVA, 60 Hz. Thawj qhov hluav taws xob yog 12.47 kV. Qhov nruab nrab voltage yog 0.208 kV. Pawg vector yog YNyn0.
300 kVA uapad mounted transformerLub tsev nyob tsis muaj -load tap changer (NLTC). Lub kais hloov pauv yog ntawm lub hau thiab cov ciaj ntswj, muab ± 2 × 2.5% tapping ntau yam, raws li CSA C227.4 Clause 5.1.9, ua kom muaj kev ua haujlwm yooj yim thiab txhim khu kev qha.
Chav tsev kuj tseem suav nrog 5-legged core kev tsim kho rau kev ruaj ntseg thiab txo cov hlau nplaum hauv GrdY-GrdY txuas nrog. Grounding yog muab los ntawm tooj liab grounding bracket bolted rau hauv av bar, ua raws li CSA C227.4, thiab tso cai rau kev ruaj ntseg txuas ntawm kev ua hauj lwm hauv av clamps.
Tsim los rau kev ua haujlwm siab, lub tshuab hluav taws xob no ua tiav 98.94% kev ua haujlwm, tsis muaj -load poob Tsawg dua lossis sib npaug ntawm 705 W thiab qhov poob qis dua lossis sib npaug li 4000 W. Ua kom muaj kev tiv thaiv sab nraum zoov, nws los nrog tus qauv CSA- ua raws cov khoom siv thiab sawv cev rau kev txhim khu kev qha, ruaj ruaj rau Canadian tis network.

02 Kev tsim khoom
2.1 Core
Lub tsib-limb core muab qhov sib nqus zoo sib nqus hauv qhov me me. Nws yog zoo meej rau ncoo -mounted transformers. Cov duab compact txuag chaw thiab nqi. Txoj kev sib nqus ua tau zoo txo qis lub zog poob thiab pab lub transformer ua haujlwm zoo dua hauv cov chaw nruj. Txhua txheej steel yog stacked nrog kev saib xyuas. Cov nplooj ntawv yog 0.30-0.35 mm tuab thiab muaj 2-4.8% silicon. Cov khoom no pab txo qis eddy tam sim no thiab hysteresis poob.
2.2 Cua txias
Tag nrho cov coils tau ua tib zoo raug mob nrog txhuas ntawv ci thiab hlau. Lawv kis tau cua sov zoo thiab ua kom poob qis. Nrog kev tswj hwm impedance thiab kev ua haujlwm siab, cov tshuab hloov pauv no ua haujlwm tau zoo thiab npaj txhij rau pad-mounted installations. Featuring YNyn0 peb -theem layout, txhua theem yog tes- raug mob los ntawm cov kws tshaj lij los xyuas kom muaj kev sib txuas nruab nrab thiab sib npaug sib nqus.
2.3 Tank
Lub 300 kVA ncoo mounted transformer nyob rau hauv enclosures yuav tsum me me - steel kaw tso tsheb hlau luam nrog bolted npog. Tus qauv tsim yuav tsum xyuas kom muaj kev ncaj ncees nyob rau hauv kev ntsuas 50 kPa, tsis muaj qhov to lossis qhov tsis sib haum xeeb mus tas li ntau dua 0.25% ntawm cov kab pheeb ces kaum. Tank yuav tsum yog huab cua- thiab tamper- tiv taus, nruab nrog cov pentahead bolts rau CSA C227.4 qhov yuav tsum tau ua.
2.4 Kev sib dhos zaum kawg
Thaum lub sij hawm transformer los ua ke txheej txheem, peb tsis tsuas yog ua hauj lwm nyob rau hauv ib tug huv chav tsev nrog tas li kub thiab av noo, tab sis kuj tau tsim ib tug txheej txheem kev khiav hauj lwm system. Los ntawm kev sib dhos transformer mus rau kev sib txuas ua ke, txhua kauj ruam yog coj los ntawm cov txheej txheem meej, ua kom tiav, ua kom tiav qhov tseeb thiab raug nyob rau hauv ib puag ncig lean. Qhov kev tsom xam ntawm ob qho tib si ib puag ncig thiab cov txheej txheem ua kom peb cov khoom lag luam muaj kev tswj hwm qib siab ntawm kev ua haujlwm zoo.
