Ntawm Load Kais Changer Roj Immersed Fais Fab Transformer Technical Application

Hais txog cov roj-immersed transformer nrog on-load voltage kev cai, txhawm rau txhim kho qhov zoo ntawm lub zog, lub load-regulated voltage yog siv los txo cov kab poob. Vim tias qhov kev hloov pauv ntawm cov roj-immersed transformer, qhov tsis ua haujlwm ntawm lub cev tsis tuaj yeem hloov pauv. Txhawm rau kom tsis txhob muaj hluav taws xob tawg, lub kaw lus yuav tsum muaj peev xwm tuag txaus. Hauv kev tsim thiab kev npaj tsis muaj txiaj ntsig ntawm daim phiaj, nws yog ib qho tsim nyog yuav tsum tau ua tib zoo xav txog kev nce qhov voltage ntawm daim phiaj. Lub kaw lus paub txog cov txheej txheem sib npaug thiab sib npaug ntawm lub zog tsis muaj zog, ua kom muaj peev xwm txaus thaum muaj xwm txheej ceev, cuam tshuam qhov hluav taws xob los ntawm kev hloov pauv, thiab zam qhov hluav taws xob loj. Thaum lub kaw lus muaj kev kub ntxhov loj thiab qhov hluav taws xob poob qis heev, tus neeg tswj hwm yuav tsum ua raws sijhawm los txiav tawm qhov kev hloov pauv thiab ib feem ntawm cov khoom thauj, tshem tawm qhov tsis txaus ntawm lub zog tsis muaj zog thiab tsis muaj zog hauv lub cev, lossis teeb tsa lub tshuab tsis siv neeg. shedding ntaus ntawv los tswj qhov system. Roj immersed transformer tswj, kev kub ceev kev khiav hauj lwm thiab kev txwv bureaus offset no cov teebmeem. Kev sib koom ua ke ib nrab txhim kho mus rau hauv lub network-wide lossis loj network sib tsoo.

Raws li Cov Lus Qhia Txog Kev Siv Hluav Taws Xob, ntxiv rau 220 kV, kuj tseem muaj cov hluav taws xob nkag mus rau kev txhim kho cov hloov roj-immersed transformers thiab hloov roj-immersed transformers (piv txwv li, tsheb npav junctions ntawm kev xa thiab tau txais sab ntawm cov chaw nres tsheb fais fab nrog loj. output variations). txuas ntxiv. Ntawm lawv, daim phiaj hluav taws xob yuav hloov tau zoo heev. Feem ntau, nws tsis haum rau kho qhov load voltage. Load voltage hloov. Hais txog qhov muaj hluav taws xob siab thiab muaj peev xwm loj, nws tau nruab nrog cov ceg hloov pauv hloov pauv hloov pauv (nrog rau cov kauj ruam-up load hloov submerged transformers thiab xov hlau thauj khoom hloov submerged transformers) txhawm rau txhim kho kev ntseeg tau thiab tiv thaiv resonant tshaj-voltage kom deb li deb tau yam tsis muaj av, tsuas yog thaum tsim nyog. tuaj yeem hloov kho hauv huab cua voltage hom. Cov roj siab immersed transformer rau tag nrho cov kev hloov pauv voltage yog tiv thaiv los ntawm zinc oxide surge arrester rau absorbing voltage.

Thaum ob lub tshuab hloov pauv ua haujlwm nyob rau hauv tib lub sijhawm, qhov ntsuas tam sim no ntawm cov roj-immersed transformer ntawm 85 feem pua ​​​​ntawm cov keyboards qis dua qhov kev tso cai hloov. Qhov ntsuas load tam sim no ntawm cov roj-immersed transformer rau 85 feem pua ​​​​ntawm cov keyboards yog siab tshaj qhov tso cai hloov. Nyob rau tib lub sijhawm, txhawm rau txhawm rau txhawm rau txhawm rau hloov pauv ntawm ob lub roj-immersed transformers thaum lub sijhawm hloov kho, yuav tsum muaj kev tiv thaiv asynchronous txhim khu kev qha. Ua tib zoo ua raws li Kev Tswj Xyuas Kev Tswj Xyuas Hluav Taws Xob Voltage Failure Regulations. Nyob rau hauv cov roj-immersed hom, muaj voltage tswj transformer tswj nyob rau hauv lub voltage tswj ntau yam. Lub zog xa hluav taws xob hauv txhua qib tuaj yeem them nyiaj rau qhov kev txiav tawm thaum qhov hluav taws xob theem ntawm qhov zoo ntawm lub davhlau ya nyob twg hloov pauv raws li kev hloov pauv ntawm kev thauj khoom thiab ntws, kom paub txog qhov kev pom zoo ntawm kev tswj hwm qhov system voltage thiab reactive zog.
