Transformer Kais Changer Hluav Taws Xob Tswj
Transformers yog cov khoom siv tsis tseem ceeb hauv cov tshuab hluav taws xob hluav taws xob, ua rau kev hloov pauv thiab xa hluav taws xob hluav taws xob kom tau raws li kev xav tau ntawm lub zog sib txawv ntawm cov xwm txheej sib txawv. Thaum lub sij hawm transformer ua hauj lwm, kom haum raws li qhov sib txawv load xav tau thiab voltage sib txawv ntawm transformer windings, nws yog tsim nyog los kho tus transformer transformation piv nrog ib tug kais changer. Kais changers tuaj nyob rau hauv ob lub ntsiab: off-load tap changers (OLTC), uas yuav ua tau thaum lub transformer khiav, thiab on-load kais changers (LTC), uas yuav tsum tau muaj zog cuam tshuam rau lub lag luam.
Rau transformers nrog ntau tus kais sib piv, tus kais hloov pauv yog siv los kho qhov hloov pauv qhov voltage piv. Cov cuab yeej no ua haujlwm los ntawm kev hloov kho cov kev sib txuas ntawm transformer windings los hloov qhov voltage piv. Cov hauv qab no muab cov ncauj lus kom ntxaws qhia txog kev tswj hluav taws xob ntawm transformer kais changers.
Txoj Cai Ua Haujlwm ntawm Transformer Kais Changers
Lub transformer kais hloov pauv yog lub tshuab hluav taws xob tswj kev hloov pauv, feem ntau muaj nyob rau hauv phau ntawv los yog hluav taws xob cov ntaub ntawv. Lub kais hloov lub tshuab ua haujlwm los ntawm kev hloov pauv kev sib txuas ntawm lub tshuab hluav taws xob windings los kho qhov voltage piv. Lub hauv paus ntsiab lus ua haujlwm yog nyob ntawm ob lub ntsiab lus tseem ceeb:
Lub tshuab hluav taws xob ntawm lub tshuab hluav taws xob hloov hluav taws xob muaj cov kais hloov lub cev, lub zog siv hluav taws xob, thiab kev ua haujlwm mechanism.
Lub tshuab fais fab feem ntau siv lub tshuab hluav taws xob lossis hluav taws xob los tsav lub kais hloov pauv, ua kom lub tshuab hloov pauv hloov pauv thiab kho qhov ntsuas qhov sib piv. Lub tshuab ua haujlwm tso cai rau kev cuam tshuam los ntawm tes, tes, lossis cov nyees khawm los hloov cov kev taw qhia thiab txoj hauj lwm ntawm lub hwj chim mechanism.
Lub kais hloov lub cev yog tsim los tiv taus hluav taws xob loj thiab kev ntxhov siab, nrog rau tej yam kev mob xws li kev vibrations thiab shocks. Tsis tas li ntawd, cov khoom siv sab hauv feem ntau raug kaw los tiv thaiv plua plav, noo noo, thiab corrosion.
Kev tswj hluav taws xob ntawm lub tshuab hluav taws xob hloov pauv muaj xws li cov khoom sib txuas, txwv cov keyboards, cables, thiab relays. Tus contactor hloov lub xeev ntawm tus kais hloov pauv siv cov neeg kho tshuab. Txwv cov keyboards nres tus kais hloov pauv los ntawm kev tig dhau ntawm ib txoj haujlwm tshwj xeeb, muab cov lus tawm tswv yim rau tus contactor kom cia li nres lub tshuab tsav tsheb. Cables yog siv rau hluav taws xob teeb liab kis tau tus mob thiab lub hwj chim mov, thaum relays nthuav kev tswj ntau yam ntawm hluav taws xob teeb liab.
Hauv kev tswj hluav taws xob, cov khoom siv hluav taws xob ua lub luag haujlwm tseem ceeb hauv kev nthuav tawm cov cim hluav taws xob (tam sim no lossis voltage) los tswj cov khoom siv hluav taws xob ntau dua. Nyob rau hauv transformer kais changers, relays ua raws li intermediaries, xa cov kev ua hauj lwm teeb liab mus rau lub hwj chim mechanism, uas tsav tus kais changer los kho qhov voltage piv.
Daim ntawv thov ntawm Transformer Kais Changers
Transformer kais hloov pauv feem ntau yog siv nyob rau hauv ntau tus kais transformers uas yuav tsum tau hloov kho rau qhov voltage piv kom tau raws li qhov sib txawv load xav tau. Hauv kev lag luam fais fab, kais hloov pauv yog siv hauv nruab nrab thiab me me transformers thiab lwm yam khoom siv hluav taws xob siab. Piv txwv li, kais hloov pauv tuaj yeem siv rau cov tshuab hluav taws xob, hloov pauv hloov pauv, faib cov khoom siv hluav taws xob, thiab lwm yam khoom siv kom ntseeg tau tias lub zog sib kis tau zoo thiab kev hloov pauv tau zoo.
Hauv cov ntawv thov kev lag luam, transformer kais hloov pauv yog qhov tseem ceeb sib npaug. Piv txwv li, hauv kev lag luam tshuab hnyav, hluav taws xob tswj vaj huam sib luag siv cov kais hloov pauv los tswj cov hluav taws xob tawm hluav taws xob thiab lub zog. Hauv kev lag luam xws li roj hmab thiab yas, kais hloov pauv kuj tseem siv los tswj cov khoom siv hluav taws xob ntau zaus thiab hluav taws xob hluav taws xob cua sov, ua kom cov zis tam sim no thiab voltage.
Kev tu ntawm Transformer Kais Changers
Txhawm rau ua kom lub sijhawm ntev thiab ruaj khov ntawm kev hloov pauv hloov pauv hloov pauv, kev saib xyuas niaj hnub yog qhov tseem ceeb. Kev tu vaj tse feem ntau suav nrog cov hauv qab no:
1. Mechanical Cheebtsam
Cov khoom siv hluav taws xob ntawm tus kais hloov pauv muaj xws li lub cev hloov pauv lub cev, lub zog siv hluav taws xob, thiab kev ua haujlwm mechanism. Thaum lub sijhawm ua haujlwm niaj hnub, nws yog ib qho tseem ceeb uas yuav tsum tau ntxuav cov plua plav thiab cov khib nyiab los ntawm cov khoom no thiab xyuas kom lub sijhawm ua haujlwm zoo, kev sib dhos ntsug, thiab qib kom tsis txhob muaj teeb meem sib cuag lossis ua tsis raug.
Kev kho dua tshiab txhua xyoo yuav tsum koom nrog kev tshem tawm tag nrho, tu, thiab hloov cov khoom siv uas tsis zoo.
2. Cov khoom siv hluav taws xob
Cov khoom siv hluav taws xob muaj xws li contactor, txwv cov keyboards, relays, cables, thiab thaiv. Kev saib xyuas niaj hnub yuav tsum suav nrog kev txheeb xyuas ntawm cov hluav taws xob sib txuas kom ntseeg tau tias cov teeb liab ncaj ncees. Tsis tas li ntawd, cov ntsiab lus ntawm cov contactors yuav tsum tau kuaj xyuas rau hnav lossis oxidation thiab hloov raws li qhov tsim nyog. Cov hlau yuav tsum raug kuaj xyuas kom zoo, thiab cov cables yuav tsum tau kuaj xyuas qhov kev puas tsuaj, xws li tawg lossis tawg, thiab kho lossis hloov raws li xav tau kom ntseeg tau tias kev ua haujlwm ruaj khov.
3. Roj Immersion Tshooj
Rau multi-kais transformers nrog roj immersion, yuav tsum muaj kev saib xyuas tshwj xeeb. Cov roj qib yuav tsum tau khaws cia nyob rau hauv qhov kev teev tseg, thiab cov roj yuav tsum tau kuaj xyuas kom muaj xim, tsw, thiab pom tseeb. Yog tias pom muaj teeb meem, cov roj yuav tsum tau hloov kom ntseeg tau tias kev ua haujlwm ntawm lub tshuab hluav taws xob zoo. Tsis tas li ntawd, thaum lub sij hawm loj overhauls ntawm tus kais changer, cov roj immersion seem yuav tsum tau ntxuav thiab refilled.
