25 kVA Transformer Light Ncej-13.8/0.24 kV|Guyane 2025

01 General

1.1 Project Background

Xyoo 2025, peb cov neeg siv khoom ntev ntev hauv Guyana tau tso lwm qhov kev txiav txim ntau, suav nrog 50 units ntawm 25 kVA ib zaug -theem ncej- mounted transformers, nrog rau 50 kVA thiab 100 kVA qauv. Qhov kev yuav khoom rov qab no qhia txog lawv txoj kev ntseeg txuas ntxiv hauv qhov zoo thiab kev ua tau zoo ntawm peb cov khoom. Nrog rau kev thov kom muaj hluav taws xob nyob deb nroog, kev hloov kho vaj tse, thiab kev siv hluav taws xob tsis zoo, cov 25 kVA transformers yog qhov tshwj xeeb tshaj yog rau cov cheeb tsam qis uas muaj kev ruaj ntseg, kev cia siab, thiab kev ua haujlwm tseem ceeb.

Cov transformers no ua raws li IEEE & ANSI C57.12.00 tus qauv, muaj 13.8 kV thawj qhov hluav taws xob thiab 120/240 V dual cov zis tawm, ua nrog tooj liab windings, 2% impedance, thiab ± 2 × 2.5% tsis muaj -load tap changer. Nrog rau txoj kev ua kom txias ntawm ONAN, lawv muab kev lag luam txhim khu kev qha ntawm 60 Hz, tsis muaj -load poob ntawm 98 W thiab thauj khoom poob ntawm 289 W, ua rau lawv muaj zog- kev daws teeb meem zoo rau cov khoom siv hluav taws xob hauv thaj chaw deb. Lawv tuaj yeem ua haujlwm raws li lub teeb ncej transformers hauv cov teeb pom kev zoo rau pej xeem, chaw nres tsheb, lossis txoj kev- theem kev faib tawm, qhov loj me me thiab kev ua tau zoo yog qhov tseem ceeb.

Nrog rau ntau xyoo ntawm kev paub hauv kev tsim khoom siv hluav taws xob, peb tshwj xeeb hauv kev tsim thiab tsim ib qho -theem ncej- mounted transformers, muab cov kev daws teeb meem zoo heev kom tau raws li ntau hom kev thov. Peb cov khoom siv dav siv thoob plaws North thiab South America, txhawb nqa los ntawm kev ua raws li cov qauv thoob ntiaj teb, kev tswj xyuas zoo, thiab kev pabcuam teb.

02 Kev tsim khoom

2.1 Core

Txhawm rau txhim kho kev ua haujlwm ntawm lub zog thiab kev cia siab rau kev ua haujlwm, cov koob no siv lub zog-txuag lub qhov txhab uas paub txog kev poob qis, tsis muaj suab nrov, thiab ua haujlwm ntev. Lub hauv paus tseem ceeb yog coated rau kev tiv thaiv - noo noo thiab tiv thaiv - kev tiv thaiv corrosion, ua kom muaj kev ruaj ntseg hauv qhov chaw sab nraum zoov.

2.2 Cua txias

Featuring ob lub HV bushings thiab peb LV bushings, no transformer siv tooj liab ntawv ci rau lub siab-voltage winding thiab tooj liab conductor hlau rau qhov tsawg-voltage sab. Tag nrho cov coils tau siv lub tshuab nqus tsev kom qhuav thiab rwb thaiv tsev kho mob kom ntseeg tau tias lub zog dielectric thiab kev ua haujlwm ruaj khov hauv cov huab cua sab nraum zoov.

2.3 Tank

Lub tank yog tsim los ntawm siab - zoo me me hlau thiab coated nrog epoxy xim rau superior corrosion kuj. Nws nta lub kaw lus tsim uas dhau qhov kev ntsuam xyuas airtightness, ua kom muaj kev sib khi zoo heev los tiv thaiv cov roj xau thiab ya raws. Ntsuas 885mm nyob rau hauv qhov siab, 660mm nyob rau hauv dav, thiab 580mm nyob rau hauv ntev, nws txhawb ONAN txias kom ruaj khov transformer ua hauj lwm thiab npaum kub dissipation.

Thaum lub sij hawm sib dhos, lub siab -voltage bushings yog mounted rau saum thiab siv lub qhov muag ntsia liaj qhov rooj hom ntsuas ntawm 18 kV nrog ib tug xob laim impulse withstand voltage ntawm 125 kV, muab zoo heev creepage nrug thiab hluav taws xob rwb thaiv tsev. Qhov qis-voltage bushings yog sab-mounted, ntsuas ntawm 250 A. Lub siab nyem valve tseem raug teeb tsa, nrog rau kev tso tawm ntau ntawm 0.03 ± 0.01 MPa, ua kom muaj kev nyab xeeb nyob rau hauv qhov kub thiab txias lossis txawv txav sab hauv.
