Transformers txo qis qhov sib kis tau zoo heev rau hauv voltage tsawg dua 10 000 volts, uas yog tsim rau kev faib khoom.
Dab tsi yog cov kauj ruam-down voltages ntawm substation?
Lub kauj ruam-down substation tuaj yeem hloov pauv qhov hluav taws xob xa mus rau qhov hluav taws xob subtransmission, feem ntau 69 kV. Cov kab hluav taws xob subtransmission tuaj yeem ua lub hauv paus rau cov chaw faib khoom.
YYuav ua li cas hom transformer siv nyob rau hauv substation?
Substation transformers feem ntau muaj nrog ib qho ntawm 3 cov kua sib txawv: Mineral roj los yog silicone transformer rojThawj qhov hluav taws xob ntawm lub tshuab hluav taws xob substation feem ntau yog nyob ntawm 2.4 kV txog 69 kV nyob rau hauv 225 txog 20, 000 kVA qhov ntau thiab tsawg, tab sis 600 volt txog 35 kV qhov ntsuas hluav taws xob theem nrab kuj muaj.
Vim li cas kauj ruam-down transformer siv hauv substation?
Ntawm cov chaw faib khoom, lawv yog siv los txo qhov hluav taws xob los ntawm cov kab sib kis. … Txawm nyob rau hauv kev lag luam, qhov yuav tsum tau txo qis voltage yog tau raws li customized step-down transformers.
Lub luag haujlwm tseem ceeb ntawm kauj ruam nqis transformer yog dab tsi?
Transformers raug cais los ntawm lawv txoj haujlwm, uas yog nce lossis nqis. Cov kauj ruam-up transformers nce qhov voltage ntawm cov khoom tam sim no, thaum cov kauj ruam-down transformers txo cov khoom tam sim no qhov voltage.

Under-Frequency Load Shedding (UFLS) yog ib qho txheej txheem los tswj lub zog ruaj khov los ntawm kev tshem tawm cov khoom dhau ntawm qee qhov ntawm lub cev… Lub tswv yim muaj peev xwm txhim kho qhov zaus teb ntawm cov koog pov txwv . Dab tsi yog qhov undervoltage load shedding?
Yuav ua rau lub log qis qis ua rau skidding?
Stopping Sijhawm Log Tsheb uas tsis muaj zog siv sijhawm ntev dua los nres, tshwj xeeb tshaj yog nyob rau ntawm txoj kev ntub dej. … Cov log tsheb qis yuav plam yooj yim dua rau ntawm cov dej khov thiab cov chaw ntub dej, tab sis lawv kuj tseem yuav hla mus ntxiv rau ntawm txoj kev qhuav .
Rau chav tsev transformer hv voltage yuav tsum yog?
Kev piav qhia: HV voltage yog qhov qis, sib npaug ntawm lub tshuab hluav taws xob tso zis hluav taws xob, piv txwv li feem ntau nruab nrab ntawm 11 thiab 23.5 kV LV voltage feem ntau yog 11 kV nominal, txawm hais tias nyob rau Qee qhov sib xyaw ua ke roj turbine chaw nres tsheb 6.
Yuav ua li cas qis qis ua rau lub cav lub teeb?
Cov dej txias qis hauv lub tshuab hluav taws xob ntawm koj lub tsheb tuaj yeem ua rau lub teeb pom kev tsis zoo (MIL), tseem hu ua "check engine" lub teeb. Cov dej txias qis tuaj yeem cuam tshuam rau qhov kub thiab txias ntawm lub cav, uas tiv thaiv los ntawm kev tiv thaiv kab mob .
Nyob rau hauv ib qho alternator qhov zaus ntawm voltage generated nyob ntawm?
Cov zis zaus ntawm lub tshuab hloov pauv yog txiav txim siab los ntawm ob yam, rotor ceev thiab tus lej ntawm tus ncej . Ntawm dab tsi yog qhov generated alternator voltage nyob ntawm seb? Lub tshuab hluav taws xob tsuas yog muab lub zog tawm raws li qhov xav tau los ntawm qhov system.
