Cov laj thawj rau qhov kev sim cuam tshuam ntawm qhov tshiabtransformerlos yog overhauled transformer ua ntej nws yuav raug muab tso rau hauv lub lag luam yog raws li nram no:
(1) Tshawb xyuas cov rwb thaiv tsev ntawm lub transformer thiab nws cov Circuit Court rau qhov tsis muaj zog lossis qhov tsis xws luag. Thaum tsis muaj-load transformer yog rub tawm, kev khiav hauj lwm overvoltage yuav raug generated. Thaum lub ntsiab lus nruab nrab ntawm lub zog hluav taws xob tsis yog hauv av los yog hauv av los ntawm arc suppression coil, lub overvoltage amplitude tuaj yeem ncav cuag 4-4.5 npaug ntawm theem voltage. Thaum lub ntsiab lus nruab nrab yog ncaj qha hauv av, lub overvoltage amplitude tuaj yeem ncav cuag 3 zaug ntawm theem voltage. Txhawm rau kuaj seb lub zog hluav taws xob hluav taws xob puas tuaj yeem tiv taus qhov hluav taws xob tag nrho lossis kev khiav hauj lwm overvoltage, nws yog ib qho tsim nyog yuav tsum tsis txhob muaj qhov ntsuas hluav taws xob tag nrho ua ntej lub tshuab hloov pauv. Yog hais tias lub transformer thiab nws cov Circuit Court muaj cov rwb thaiv tsev tsis muaj zog, lawv yuav raug cuam tshuam los ntawm kev khiav hauj lwm overvoltage tawg.
(2) Tshawb xyuas seb qhov kev tiv thaiv kev sib txawv ntawm qhov sib txawv ntawm qhov sib txawv puas ua haujlwm tsis raug. Thaum lub zog hluav taws xob muab tso rau hauv qhov tsis muaj qhov hloov pauv, qhov excitation inrush tam sim no yuav raug tsim tawm, thiab nws cov nqi tuaj yeem ncav cuag 6-8 npaug ntawm qhov ntsuas tam sim no. Excitation inrush tam sim no pib lwj sai dua, feem ntau yog O.5-1s tuaj yeem txo tau rau 0.25-0.5 npaug ntawm qhov ntsuas tam sim no, tab sis tag nrho cov attenuation tau ua tiav rau lub sijhawm ntev, transformers me me thiab nruab nrab ntawm ob peb vib nas this, cov transformers loj tuaj yeem ncav cuag 10-20s, yog li thawj zaug attenuation ntawm excitation inrush tam sim no, feem ntau ua rau qhov sib txawv tiv thaiv kev ua haujlwm tsis zoo, uas ua rau cov transformer tsis tuaj yeem muab tso rau hauv. Yog li ntawd, thaum tsis muaj load cuam tshuam kaw, nyob rau hauv qhov kev txiav txim ntawm excitation inrush tam sim no, kev sib txuas, cov yam ntxwv thiab teeb tsa tus nqi ntawm qhov kev tiv thaiv sib txawv tuaj yeem raug kuaj xyuas, thiab kev ntsuam xyuas thiab kev txiav txim siab seb qhov kev tiv thaiv puas tuaj yeem muab tso rau hauv.
(3) Tshawb xyuas lub zog txhua yam ntawm transformer. Vim hais tias cov excitation inrush tam sim no generates ib tug ntau ntawm hluav taws xob hwj chim, nyob rau hauv thiaj li yuav xyuas cov neeg kho tshuab lub zog ntawm lub transformer, nws yog tsim nyog los ua tsis-load cuam tshuam kev ntsuam xyuas.
Raws li cov kev cai, tus naj npawb ntawm tag nrho-voltage tsis-load cuam tshuam kev xeem, cov khoom tshiab tawm tswv yim, yuav tsum muaj kev cuam tshuam tas li 5 zaug; Tom qab kev kho dua tshiab tau muab tso rau hauv kev ua haujlwm, nws yuav tsum raug cuam tshuam rau 3 zaug sib law liag. Txhua lub sijhawm cuam tshuam tsis pub tsawg dua 5min, ua ntej kev ua haujlwm yuav tsum raug xa mus rau qhov chaw saib xyuas lub tshuab hloov pauv, xyuas qhov hloov pauv hloov pauv tsis muaj qhov sib txawv, yog tias muaj qhov tsis txaus ntseeg yuav tsum nres tam sim ntawd.
Cia khiav rau ntau tshaj 10 feeb tom qab qhov cuam tshuam thawj zaug thiab tos ntev dua 5 feeb ua ntej qhov cuam tshuam tom ntej.
Raws li yog vim li cas qhov kev kwv yees tshwj xeeb teem rau 5 zaug yog qhov tshwj xeeb yog qhov xaus ntawm kev xav txog txhua yam muaj zog overvoltage excitation inrush tam sim no
